How can I dynamically name an array in Javascript? | <p>I am using jQuery and JSON to pull data from a database. Each row of the database is a different product and each product has a number of properties associated with it.</p>
<p>What I'm trying to do in js, is create a named array for each product containing all of the products properties. I know how to pull the data from JSON. I know how to construct the Array.</p>
<p>What I don't know is how to create an array name dynamically. Can someone help me out?</p>
<p>I am trying to name the array based on a field in the database. In the structure of my existing and working script, it's referenced as data.cssid. I'd like to use the value of data.cssid as the name of the array and then populate the array.</p>
<pre><code>$.getJSON("products.php",function(data){
$.each(data.products, function(i,data){
var data.cssid = new Array();
data.cssid[0] = data.productid;
...
etc
});
});
</code></pre>
<p>I know the code above is completely wrong, but it illustrates the idea. Where I declare "var data.cssid", I want to use the actual value of data.cssid as the name of the new array.</p>
<p>EDIT:</p>
<p>I've tried the methods mentioned here (except for eval). The code is below and is not really that different than my original post, except that I'm using a Object constructor.</p>
<pre><code>$(document).ready(function(){
$.getJSON("productscript.php",function(data){
$.each(data.products, function(i,data){
var arrayName = data.cssid;
obj[arrayName] = new Array();
obj[arrayName][0] = data.productid;
obj[arrayName][1] = data.productname;
obj[arrayName][2] = data.cssid;
obj[arrayName][3] = data.benefits;
alert(obj[arrayName]); //WORKS
alert(obj.shoe); //WORKS WHEN arrayName = shoe, otherwise undefined
});
});
});
</code></pre>
<p>The alert for the non-specific obj[arrayName] works and shows the arrays in all their magnificence.
But, when I try to access a specific array by name alert(obj.shoe), it works only when the arrayName = shoe. Next iteration it fails and it can't be accessed outside of this function.</p>
<p>I hope this helps clarify the problem and how to solve it. I really appreciate all of the input and am trying everything you guys suggest.</p>
<p>PROGRESS (THE SOLUTION):</p>
<pre><code>$(document).ready(function(){
$.getJSON("productscript.php",function(data){
$.each(data.products, function(i,data){
var arrayName = data.cssid;
window[arrayName] = new Array();
var arr = window[data.cssid];
arr[0] = data.productid;
arr[1] = data.productname;
arr[2] = data.cssid;
arr[3] = data.benefits;
alert(window[arrayName]); //WORKS
alert(arrayName); //WORKS
alert(shoe); //WORKS
});
});
});
function showAlert() {
alert(shoe); //WORKS when activated by button click
}
</code></pre>

How do I fix the 'Out of range value adjusted for column' error? | <p>I went into phpMyAdmin and changed the value for an integer(15)field to a 10-digit number, so everything should work fine. I entered the value '4085628851' and I am receiving the following error:</p>
<blockquote>
<p>Warning: #1264 Out of range value
adjusted for column 'phone' at row 1</p>
</blockquote>
<p>It then changes the value to '2147483647'.</p>
<p>After some googling, I found this article that explains how to fix the problem. <a href="http://webomania.wordpress.com/2006/10/01/out-of-range-value-adjusted-for-column-error/" rel="noreferrer">http://webomania.wordpress.com/2006/10/01/out-of-range-value-adjusted-for-column-error/</a>, but I don't know how to login to the Mysql shell. </p>

AngularJS get formatted date in ng-model | <p>I have following text input filled by model value in timestamp:</p>
<pre><code><input type="datetime" ng-model="workerDetail.dateOfBirth" class="form-control" id="date_of_birth" />

<p>It displays value in input as given timestamp. </p>
<p>I would like to convert value which is visible in input into formatted date (YYYY/MM/DD), but in model should be always as timestamp. </p>
<p>I tried to do it by this way:</p>
<pre><code>{{workerDetail.dateOfBirth | date:'MMM'}}

Change Toolbar color in Appcompat 21 | <p>I am testing out the new Appcompat 21 Material Design features. Therefore I've created a Toolbar like this:</p>
<pre><code><android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/activity_my_toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:theme="@style/ThemeOverlay.AppCompat.ActionBar"/>
</code></pre>
<p>and included it in my main layout file.</p>
<p>Then I've set it as supportActionBar like that:</p>
<pre><code>Toolbar toolBar = (Toolbar)findViewById(R.id.activity_my_toolbar);
setSupportActionBar(toolBar);
</code></pre>
<p>It's working, but somehow I can't quite figure out how to customize the toolbar. It's grey and the text on it is black. How should I change background and text color?</p>
<p>I've gone through this instructions:</p>
<p><a href="http://android-developers.blogspot.de/2014/10/appcompat-v21-material-design-for-pre.html" rel="noreferrer">http://android-developers.blogspot.de/2014/10/appcompat-v21-material-design-for-pre.html</a></p>
<p>What have I overseen to change colors?</p>
<pre><code> <style name="AppTheme" parent="Theme.AppCompat.Light">
<item name="android:windowActionBar" tools:ignore="NewApi">false</item>
<item name="windowActionBar">false</item>
</style>
</code></pre>
<p><strong>EDIT</strong>:</p>
<p>I was able to change the background color by adding these lines of code to the theme:</p>
<pre><code><item name="colorPrimary">@color/actionbar</item>
<item name="colorPrimaryDark">@color/actionbar_dark</item>
</code></pre>
<p>But they won't affect the text color. What am I missing? Instead of the black text and black menu button, I'd rather prefer a white text and white menu buttons:</p>

How to countercheck a Boost Error Code appropriately? | <p>I have a callback function which is bound to a <code>boost::asio::deadline_timer</code>. Now the function is called when the timer is cancelled or it expires. Since I need to distinguish between this two cases I need to check the passed Error code. The basic code would be like this:</p>
<pre><code>void CameraCommand::handleTimeout(const boost::system::error_code& error)
{
std::cout << "\nError: " << error.message() << "\n";
return;
}
</code></pre>
<p>Now when the Handler is called because the timer expired the error code is <code>Success</code>, when the timer is cancelled the error code is <code>Operation canceled</code>.</p>
<p>Now my question would be, how to appropriately check what happened?</p>
<p>Suggestion 1:</p>
<pre><code>if( error.message() == "Success" )
{
// Timer expired
}
else
{
// Timer cancelled
}
</code></pre>
<p>Suggestion 2:</p>
<pre><code>if( error.value() == 0 )
{
// Timer expired
}
else
{
// Timer cancelled
}
</code></pre>
<p>Now my question is - is there any way to compare the error byitself and not by value or by string? Something like ( this is made up now )</p>
<pre><code>if ( error == boost::system::error::types::success )
</code></pre>
<p>Because what I don't like about the first suggestion is that I need to create a string just for check, which is kinda unnecessary in my opinion. The second way has the disadvantge that I need to look up all the error codes if I want to check for something other?
So are there any enums or ways to check for the error or do I have one of the two suggested ways?</p> | 0 |
How to instantiate, initialize and populate an array in TypeScript? | <p>I have the following classes in TypeScript:</p>
<pre><code>class bar {
length: number;
}
class foo {
bars: bar[] = new Array();
}
</code></pre>
<p>And then I have:</p>
<pre><code>var ham = new foo();
ham.bars = [
new bar() { // <-- compiler says Expected "]" and Expected ";"
length = 1
}
];
</code></pre>
<p>Is there a way to do that in TypeScript?</p>
<p><strong>UPDATE</strong></p>
<p>I came up with another solution by having a set method to return itself:</p>
<pre><code>class bar {
length: number;
private ht: number;
height(h: number): bar {
this.ht = h; return this;
}
constructor(len: number) {
this.length = len;
}
}
class foo {
bars: bar[] = new Array();
setBars(items: bar[]) {
this.bars = items;
return this;
}
}
</code></pre>
<p>so you can initialize it as below:</p>
<pre><code>var ham = new foo();
ham.setBars(
[
new bar(1).height(2),
new bar(3)
]);

How to use "routerLinkActive" with query params in Angular 6? | <p>I have a problem in Angular: I have three links, one of them has query params (due to using a resolver). If I click the first and the third link, the <code>routerLinkActive</code> is set. If I click the second link <code>routerLinkActive</code> is set too. But if I change the query parameter inside the component <code>routerLinkActive</code> gets unset.</p>
<p>So, I need to ignore the query params. But how does it work? Can anyone help me?</p>

Create .ics file dynamically | <p>I made a website for a client where they can post events. Instead of manually creating .ics files from iCal for every event and uploading it, I though it would be better to pull it out of the database and automatically create a .ics file automatically with PHP.</p>
<p>I can pull information from the database (no problem), but when converting it to a time stamp for the calendar file it a tough one. Here's what I store in the database:</p>

Cartesian Product in c++ | <p>I have been searching for weeks on how to come up with piece of code which I could applied the cartesian product. Let's say I have two arrays : </p>

int J[3] = {0,1,2};
</code></pre>
<p>So the code will takes those two arrays in apply the rule M X J
therefore we will have the pairs (1,0)(1,1)(1,2)(2,0)(2,1)(2,2) and I want the new result to be saved into a new array where each index in the array contains a pair , for example c[0] = (1,0).

JavaFX: what is the best way to display a simple message? | <p>In my application I need to display a warning/info message, but I don't know a simple way to do that because there is no JOptionPane or similar component on JavaFX.</p>
<p>There is a Popup class, but you have to set many parameters to get a decent layout/position/background color/etc for a simple message... So I want to know if there is a simple, already implemented component to display messages, maybe in a third party library if JavaFX does not offer anything decent.</p>

How do I install python_ldap on 64 bit windows 7? | <p>I'm using python 2.7.6 and in my code I have a line:</p>

new Person{FirstName = "Friend", LastName="Number2"}

return Json(person, JsonRequestBehavior.AllowGet);

When using the plugin the AddFriend method is not available during the binding.
Is it possible to populate the JavaScript Person object by using the mapping plugin or must everything be done manually?</p> | 0 |

How to change fonts in matplotlib (python)? | <p>It sounds as an easy problem but I do not find any effective solution to change the font (not the font size) in a plot made with matplotlib in python.</p>
<p>I found a couple of tutorials to change the default font of matplotlib by modifying some files in the folders where matplotlib stores its default font - see <a href="http://blog.olgabotvinnik.com/post/35807476900/how-to-set-helvetica-as-the-default-sans-serif-font-in" rel="noreferrer">this blog post</a> - but I am looking for a less radical solution since I would like to use more than one font in my plot (text, label, axis label, etc).</p> | 0 |
Is there a way to simulate GROUP BY WITH CUBE in MySql? | <p>MySql supports GROUP BY WITH ROLLUP which will return aggregates for the last x of the n columns in the group by but does not support GROUP BY WITH CUBE to take all combinations of the n columns and take aggregates.</p>
<p>I can simulate this by doing unions of GROUP BY WITH ROLLUP queries, but MySql is materializing my subquery multiple times. I am using a group by on a large subquery, so this is suboptimal. Is there a way to solve this without temporary tables?</p> | 0 |

How to add a new row to c# DataTable in 1 line of code? | <p>Is it possible to add a new row to a datatable in c# with just 1 line of code? I'm just dummying up some data for a test and it seems pretty slow to have to write something like this:</p>
<pre><code>DataTable dt= new DataTable("results");
DataRow dr1 = dt.NewRow();
dr1[0] = "Sydney";
dt.Rows.Add(dr1);
DataRow dr2 = dt.NewRow();
dr2[0] = "Perth";
dt.Rows.Add(dr2);
DataRow dr3 = dt.NewRow();
dr3[0] = "Darwin";
dt.Rows.Add(dr3);
</code></pre>
<p>I was assuming you could do something like the code below, but I can't find the correct syntax.</p>
<pre><code>dt.Rows.Add(dt.NewRow()[0]{"Sydney"});
dt.Rows.Add(dt.NewRow()[0]{"Perth"});
dt.Rows.Add(dt.NewRow()[0]{"Darwin"});
</code></pre>
<p>And yes I know in the time I've taken to write this question I could have finished coding it the long way instead of procrastinating about it :)</p>

How to make cheat sheets in Latex? | <p>I want to make cheat sheets for my personal use. I want to use this opportunity to get a good hand on <a href="http://en.wikipedia.org/wiki/LaTeX" rel="noreferrer">LaTeX</a> too. (I am already comfortable making simple documents math related in LaTeX.)</p>
<p>Now I want to try making cheat sheets in LaTeX. But I don't know how to do it. In cheat sheets, usually the page is split into multiple rectangular sections and each one has a few commands or notes inside it. Each rectangular section has a border etc.</p>
<p>How can it be done in LaTeX? Are any packages available to do this? Do you think <a href="http://en.wikipedia.org/wiki/PGF/TikZ" rel="noreferrer">TikZ</a> will be a good idea for this?</p> | 0 |
In Python how should I test if a variable is None, True or False | <p>I have a function that can return one of three things:</p>
<ul>
<li>success (<code>True</code>)</li>
<li>failure (<code>False</code>)</li>
<li>error reading/parsing stream (<code>None</code>)</li>
</ul>
<p>My question is, if I'm not supposed to test against <code>True</code> or <code>False</code>, how should I see what the result is. Below is how I'm currently doing it:</p>
<pre><code>result = simulate(open("myfile"))
if result == None:
print "error parsing stream"
elif result == True: # shouldn't do this
print "result pass"
else:
print "result fail"
</code></pre>
<p>is it really as simple as removing the <code>== True</code> part or should I add a tri-bool data-type. I do not want the <code>simulate</code> function to throw an exception as all I want the outer program to do with an error is log it and continue. </p> | 0 |

Disabling field analyzing by default in elastic search | <p>Is it possible to enable indexing of elastic search fields selectively for a type? </p>
<p>Through the mapping settings for a specific index, one can set the property </p>
<p>{ "index" : "not_analyzed" }</p>
<p>For a specific field. Since my document has too many fields and is likely to change structure in the future, I would need a mapping where fields are not analyzed by default unless specified differently.</p>

android: Data refresh in listview after deleting from database | <p>I have an application which retrieves data from DB and displays it in a list view. I have a custom adapter for the same. So when I press the "delete" button, a delete button for each row in the list is displayed. If I press that, the particular row gets deleted in the DB and the same should be reflected in the listview also. The problem is, its not reflecting this change, I should close the app and reopen or move into some other activity and get back to see the updated results.</p>
<p>So my question is: where do I call the <code>notifyDataSetChanged()</code> method to get it updated instantly?</p>
<p>Here is my customadapter view:</p>
<pre><code>public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
MenuListItems menuListItems = menuList.get(position);
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) c
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.customlist, parent, false);
}
Button ck = (Button) convertView.findViewById(R.id.delbox);
if(i){
ck.setVisibility(View.VISIBLE);}
else{
ck.setVisibility(View.GONE);
}
ck.setTag(menuListItems.getSlno());
ck.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
final Integer Index = Integer.parseInt((String) v.getTag());
final DataHandler enter = new DataHandler(c);
DialogInterface.OnClickListener dialogClickListener = new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
switch (which){
case DialogInterface.BUTTON_POSITIVE:
//Yes button clicked
enter.open();
enter.delet(Index);
enter.close();
notifyDataSetChanged();
dialog.dismiss();
break;
case DialogInterface.BUTTON_NEGATIVE:
//No button clicked
dialog.dismiss();
break;
}
}
};
AlertDialog.Builder builder = new AlertDialog.Builder(c);
builder.setMessage("Are you sure you want to Delete?").setPositiveButton("Yes", dialogClickListener)
.setNegativeButton("No", dialogClickListener).show();
}
});
TextView id = (TextView) convertView.findViewById(R.id.tvhide);
id.setText(menuListItems.getSlno());
TextView title = (TextView) convertView.findViewById(R.id.tvtitle);
title.setText(menuListItems.getTitle());
TextView phone = (TextView) convertView.findViewById(R.id.tvpnumber);
phone.setText(menuListItems.getPhone());
// ck.setChecked(menuList.)
notifyDataSetChanged();
return convertView;

What is the point of Redux Promise and Redux Promise Middleware? | <p>I've searched high and low but can't find a clear answer.</p>
<p>I've managed to wrap my head around the mechanics of Redux, <em>but</em> when I've come to the point of API calls and async action creators, I'm stuck with middleware in context of Promises.</p>
<p>Can you help me get the mess right?</p>
<p>Cotradictory pieces of the puzzle giving me headache:</p>
<ol>
<li><p>One of YT tutorials says that natively Redux dispatch method does not support promises returned from action creators--hence the need for Redux Promise library (I know the project is probably dead now and the continuation is Redux Promise Middleware).</p></li>
<li><p>Dan says in "<a href="https://stackoverflow.com/questions/36577510/what-is-the-difference-between-redux-thunk-and-redux-promise">What is the difference between redux-thunk and redux-promise?</a>" I can use promises even without middleware--just manage them in the action creator.</p></li>
<li><p>In other answers I found examples of using thunks where the action creator returned a... <strong>promise</strong> (later is was processed in the caller /<em>dispatch(myActionCreator(params).then(...)</em>/
So a promise <strong>can</strong> be returned by a thunk <strong>WITHOUT</strong> any redux-promise lib..?</p></li>
<li><p>In "<a href="https://stackoverflow.com/questions/36577510/what-is-the-difference-between-redux-thunk-and-redux-promise?rq=1">What is the difference between redux-thunk and redux-promise?</a>", the accepted answer states Redux Thunk returns functions, whereas Redux Promise returns promises.. what the heck?</p></li>
</ol>
<p>To wrap it up: what's the point of using Redux Promise or Redux Promise Middleware? Why does Redux alone not natively support promises?</p>
<p><strong>Update:</strong></p>
<p>I've just realized that in point 3 above I overlooked <code>then()</code> being <strong>attached</strong> to <code>dispatch</code> and not <strong>included</strong> in <code>dispatch()</code> args.</p> | 0 |

dest: path.join(__dirname, 'public/upload/temp')}).single('file'));
routes(app);
app.use('/public/', express.static(path.join(__dirname, '../public')));

<p>Consuming code looks like this:</p>

ext = path.extname(req.file.name).toLowerCase(),
targetPath = path.resolve('./public/upload/' + imgUrl + ext);
if (ext === '.png' || ext === '.jpg' || ext === '.jpeg' || ext === '.gif') {

} else {
fs.unlink(tempPath, function() {
if (err) throw err;
res.json(500, {error: 'Only image files are allowed.'});

jQuery Mobile after page is shown event | <p>I'm new to jquery Mobile (I'm familiar with jquery though) and I cannot find an event that runs after the page is shown.

I've already tried the pageshow event</p>

ORDER BY ASC with Nulls at the Bottom | <p>I'm writing an SQL query that connects a schools table to a districts table. Simple One-To-Many relationship where each school is attached to one district. My query is as follows:</p>
<pre><code>SELECT
schools.id AS schoolid,
schools.name AS school,
districts.id AS districtid,
districts.name AS district
FROM sms_schools AS schools
LEFT JOIN sms_districts AS districts ON schools.districtid = districts.id
WHERE 1 = 1
ORDER BY districts.name, schools.name
</code></pre>
<p>The reason I did a left join is because not every school is attached to a district. For example one school may be home schooled that may contain all students that are home schooled. That wouldn't be in a district.</p>
<p>So what I would like to do is use the ORDER BY to order as it is by district name and then school name. The only problem is that I want the null district to be at the bottom so that I can then use a group called 'Other' at the end of my output.</p>
<p>Is it possible to order by ascending with nulls at the end of the output?</p> | 0 |

# make nose fail here
except UserNotFoundException:
assert True
</code></pre>
<p>The assert is executed if the exception is raised, but if no exception is raised, it won't be executed.</p>
<p>Is there anything I can put on the commented line above so that if no exception is raised nose will report a failure?</p> | 0 |
text-overflow: ellipsis not working | <p>This is what I tried (see <a href="http://jsfiddle.net/kaJ3L/" rel="noreferrer">here</a>):</p>
<pre><code>body {
overflow: hidden;
}
span {
border: solid 2px blue;
white-space: nowrap;
text-overflow: ellipsis;
}
</code></pre>
<p>Essentially, I want the span to shrink with ellipsis when the window is made small. What did I do wrong?</p> | 0 |
iOS 8 - UIPopoverPresentationController moving popover | <p>I am looking for an effective way to re-position a popover using the new uipopoverpresentationcontroller. I have succesfully presented the popover, and now I want to move it without dismissing and presenting again. I am having trouble using the function:</p>
<pre><code>(void)popoverPresentationController:(UIPopoverPresentationController *)popoverPresentationController
willRepositionPopoverToRect:(inout CGRect *)rect
inView:(inout UIView **)view
</code></pre>
<p>I know it's early in the game, but it anyone has an example of how to do this efficiently I would be grateful if you shared it with me. Thanks in advance. </p> | 0 |
XSLT replace double quotes in variable | <p>Just to clarify, I am using XSLT 1.0. Sorry for not specifying that at first.</p>
<p>I have an XSLT stylesheet where I'd like to replace double quotes with something safe that's safe to go into a JSON string. I'm trying to do something like the following:</p>
<pre><code><xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" omit-xml-declaration="yes" />
<xsl:strip-space elements="*" />
<xsl:template match="/message">
<xsl:variable name="body"><xsl:value-of select="body"/></xsl:variable>
{
"message" :
{
"body": "<xsl:value-of select="normalize-space($body)"/>"
}
}
</xsl:template>
</xsl:stylesheet>
</code></pre>
<p>If I have XML passed in that looks like the following, this will always work just fine:</p>
<pre><code><message>
<body>This is a normal string that will not give you any issues</body>
</message>
</code></pre>
<p>However, I'm dealing with a body that has full blown HTML in it, which isn't an issue because <code>normalize-space()</code> will take care of the HTML, but not double quotes. This breaks me:</p>
<pre><code><message>
<body>And so he quoted: "I will break him". The end.</body>
</message>
</code></pre>
<p>I really don't care if the double quotes are HTML escaped or prefixed with a backslash. I just need to make sure the end result passes a JSON parser.</p>
<p>This output passes JSON Lint and would be an appropriate solution (backslashing the quotes):</p>
<pre><code>{ "body" : "And so he quoted: \"I will break him\". The end." }
</code></pre> | 0 |
Oracle VirtualBox terminated unexpectedly, with exit code -1073741819 (0xc0000005) | <p>My VirtualBox virtual machine suddenly doesn't work, instead producing an error. I don't know what is causing this error; I searched Google for a solution, but failed. I have already reinstalled it, uninstalled, rebooted and reinstalled, but to no avail.</p>
<p>What can I do to solve this problem?</p>

Getting the value or index of Combobox item? | <p>I am trying to make my GUI display information depending on the item chosen in the combobox. <code>PySimpleGUI</code> cookbook says that I should be using <code>GetSelectedItemsIndexes()</code> method, but when I try using it:</p>
<pre><code>window.Element('_COMBOBOX_').GetSelectedItemsIndexes()
</code></pre>
<p>I get this:</p>
<blockquote>
<p>AttributeError: 'Combo' object has no attribute 'GetSelectedItemsIndexes'</p>
</blockquote>
<p>I tried type this into the console:</p>
<pre><code>dir(window.Element('_COMBOBOX_'))

Trigger syntax and IF ELSE THEN | <p>I'd like to create a trigger which count the number of rows with a specific id (id_ort).
If it found more than 5 rows, I need to increment a variable.</p>

Ansible condition when string not matching | <p>I am trying to write an Ansible playbook that only compiles Nginx if it's not already present and at the current version. However it compiles every time which is undesirable.</p>

Using javascript to set value of hidden field then access value from serverside c# code | <p>I am using a nested html unordered list styled as a drop down. When the a tag within the inner lists list item is clicked it trigger some javascript which is supposed to set the value of a hidden field to the text for the link that was clicked.</p>
<p>The javascript seems to work - I used an alert to read the value from the hidden field but then when I try to put that value in the querystring in my asp.net c# code behind - it pulls the initial value - not the javascript set value.</p>

WCF readerQuotas settings - drawbacks? | <p>If a WCF service returns a byte array in its response message, there's a chance the data will exceed the default length of 16384 bytes. When this happens, the exception will be something like</p>
<blockquote>
<p>The maximum array length quota (16384)
has been exceeded while reading XML
data. This quota may be increased by
changing the MaxArrayLength property
on the XmlDictionaryReaderQuotas
object used when creating the XML
reader.</p>
</blockquote>
<p>All the advice I've seen on the web is just to increase the settings in the <code><readerQuotas></code> element to their maximum, so something like</p>
<pre><code><readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
maxArrayLength="2147483647" maxBytesPerRead="2147483647"
maxNameTableCharCount="2147483647" />
</code></pre>
<p>on the server, and similar on the client.</p>
<p>I would like to know of any drawbacks with this approach, particularly if the size of the byte array may only occassionally get very large. Do the settings above just make WCF declare a huge array for each request? Do you have to limit the maximum size of the data returned, or can you just specify a reasonably-sized buffer and get WCF to keep going until all the data is read?</p>
<p>Thanks!</p> | 0 |

Open downloaded file on Android N using FileProvider | <p>I've got to fix our App for Android N due to the FileProvider changes. I've basically read all about this topic for the last ours, but no solution found did work out for me.</p>
<p>Here's our prior code which starts downloads from our app, stores them in the <code>Download</code> folder and calls an <code>ACTION_VIEW</code> intent as soons as the <code>DownloadManager</code> tells he's finished downloading:</p>
<pre><code>BroadcastReceiver onComplete = new BroadcastReceiver() {
public void onReceive(Context ctxt, Intent intent) {
Log.d(TAG, "Download commplete");
// Check for our download
long referenceId = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, -1);
if (mDownloadReference == referenceId) {
DownloadManager.Query query = new DownloadManager.Query();
query.setFilterById(mDownloadReference);
Cursor c = mDownloadManager.query(query);
if (c.moveToFirst()) {
int columnIndex = c.getColumnIndex(DownloadManager.COLUMN_STATUS);
if (DownloadManager.STATUS_SUCCESSFUL == c.getInt(columnIndex)) {
String localUri = c.getString(c.getColumnIndex(DownloadManager.COLUMN_LOCAL_URI));
String fileExtension = MimeTypeMap.getFileExtensionFromUrl(localUri);
String mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(fileExtension);
if (mimeType != null) {
Intent openFileIntent = new Intent(Intent.ACTION_VIEW);
openFileIntent.setDataAndTypeAndNormalize(Uri.parse(localUri), mimeType);
openFileIntent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
try {
mAcme.startActivity(openFileIntent);
}
catch (ActivityNotFoundException e) {
// Ignore if no activity was found.
}
}
}
}
}
}
};

<p>This works on Android M, but breaks on N due to the popular <code>FileUriExposedException</code>. I've now tried to fix this by using the <code>FileProvider</code>, but I cannot get it to work. It's breaking when I try to get the content URI:</p>
<p><code>Failed to find configured root that contains /file:/storage/emulated/0/Download/test.pdf</code></p>
<p>The <code>localUri</code> returned from the <code>DownloadManager</code> for the file is:</p>
<p><code>file:///storage/emulated/0/Download/test.pdf</code></p>
<p>The <code>Environment.getExternalStorageDirectory()</code> returns <code>/storage/emulated/0</code> and this is the code for the conversion:</p>
<pre><code>File file = new File(localUri);
Log.d(TAG, localUri + " - " + Environment.getExternalStorageDirectory());
Uri contentUri = FileProvider.getUriForFile(ctxt, "my.file.provider", file);
</code></pre>
<p>From <code>AndroidManifest.xml</code></p>
<pre><code> <provider
android:name="android.support.v4.content.FileProvider"
android:authorities="my.file.provider"
android:exported="false"

Log4j formatting: Is it possible to truncate stacktraces? | <p>I want to log only the first few lines of Exceptions in my program. I know, I can do something like this to print only the first 5 lines of a stacktrace:</p>
<pre><code>Throwable e = ...;
StackTraceElement[] stack = e.getStackTrace();
int maxLines = (stack.length > 4) ? 5 : stack.length;
for (int n = 0; n < maxLines; n++) {
System.err.println(stack[n].toString());
}
</code></pre>
<p>But I would rather use log4j (or slf4j over log4j to be more precise) for logging. Is there a way to tell log4j that it should only print the first 5 lines of a stacktrace?</p> | 0 |
How do I remove all tinymce instances at startup? | <p>I'm dynamically creating and destroying textareas for this purpose. However, when I create a textarea and then an instance of it in tinymce--then come back to the page again, it doesn't work. I've found that the solution is to simply remove any existing instance of that same name, but I was wondering if it's possible to just do it at startup.</p>

how to handle multiple namespaces with different URI in XSD | <p>I have an XML (first.xml) which looks like ::</p>
<pre><code> <?xml version="1.0" encoding="utf-8"?>

<saw:jobStats>...........</saw:jobStats>
<saw:detailedInfo> .....</saw:detailedInfo>
<saw:fileInfo>..........</saw:fileInfo>
</saw:jobInfo>
</code></pre>
<p>The below XML (second.xml) is same as the above but with a different namespace.</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<soap:jobInfo xmlns:soap="urn://bi.webservices/v6">
<soap:jobStats>...........</saw:jobStats>
<soap:detailedInfo> .....</saw:detailedInfo>
<soap:fileInfo>..........</saw:fileInfo>
</soap:jobInfo>
</code></pre>
<p>As I have the same element and attribute names in both the xml's I am using the same xsd file to validate both.</p>
<p>XSD file ::</p>
<pre><code> <?xml version="1.0" encoding="utf-8" ?>
<xs:schema targetNamespace="com.analytics.web/report/v1.1"

elementFormDefault="qualified"
attributeFormDefault="unqualified">
</code></pre>
<p>After including xmlns:soap="urn://bi.webservices/v6" the schema validation failed for second.xml saying unkown element "soap:jobinfo". I poked around and found the targetNamespace value should be same as the namespace URI.
Please let me know how to use the same XSD for two different namespaces having different URIs.</p> | 0 |

JMeter: How to count JSON objects in an Array using jsonpath | <p>In JMeter I want to check the number of objects in a JSON array, which I receive from the server. </p>
<p>For example, on a certain request I expect an array with 5 objects.</p>
<p>[{...},{...},{...},{...},{...}]</p>
<p>After reading this: <a href="https://stackoverflow.com/questions/13745332/count-members-with-jsonpath/20498983#20498983">count members with jsonpath?</a>, I tried using the following JSON Path Assertion:</p>
<ul>
<li>JSON Path: $</li>
<li>Expected value: hasSize(5)</li>
<li>Validate against expected value = checked</li>
</ul>
<p>However, this doesn't seem to work properly. When I actually do receive 5 objects in the array, the response assertion says it doesn't match.</p>
<p>What am I doing wrong?
Or how else can I do this?</p> | 0 |
What's the right way to reference a parameter in Doxygen? | <p>I have the following Doxygen documentation for a function:</p>
<pre><code>/**
@brief Does interesting things
@param[in] pfirst The first parameter: a barrel full of monkeys
@pre
"pfirst" must have been previously passed through BarrelFiller()
*/
</code></pre>
<p>Note that <code>pfirst</code> is a parameter, and that it is referenced in the preconditions.</p>
<p>I've surrounded it with quotation marks here because I want to stand it off from the rest of the text. But it would be nice to do this in such a way that Doxygen will highlight the command and, preferably, link it to the parameter definition. Is there a way to do this?</p>
<p>It would be especially nice if this would happen using only the default configuration (or minor alterations thereof).</p> | 0 |

Python: simple list merging based on intersections | <p>Consider there are some lists of integers as:</p>
<pre><code>#--------------------------------------
0 [0,1,3]
1 [1,0,3,4,5,10,...]
2 [2,8]
3 [3,1,0,...]
...
n []
#--------------------------------------
</code></pre>
<p>The question is to merge lists having at least one common element. So the results only for the given part will be as follows:</p>
<pre><code>#--------------------------------------
0 [0,1,3,4,5,10,...]
2 [2,8]
#--------------------------------------
</code></pre>
<p><strong>What is the most efficient way to do this on large data (elements are just numbers)?</strong>
Is <code>tree</code> structure something to think about?
I do the job now by converting lists to <code>sets</code> and iterating for intersections, but it is slow! Furthermore I have a feeling that is so-elementary! In addition, the implementation lacks something (unknown) because some lists remain unmerged sometime! Having said that, if you were proposing self-implementation please be generous and provide a simple sample code [apparently <strong>Python</strong> is my favoriate :)] or pesudo-code.<br>
<strong>Update 1:</strong>
Here is the code I was using:</p>
<pre><code>#--------------------------------------
lsts = [[0,1,3],
[1,0,3,4,5,10,11],
[2,8],
[3,1,0,16]];
#--------------------------------------
</code></pre>
<p>The function is (<strong>buggy!!</strong>):</p>
<pre><code>#--------------------------------------
def merge(lsts):
sts = [set(l) for l in lsts]
i = 0
while i < len(sts):
j = i+1
while j < len(sts):
if len(sts[i].intersection(sts[j])) > 0:
sts[i] = sts[i].union(sts[j])
sts.pop(j)
else: j += 1 #---corrected
i += 1
lst = [list(s) for s in sts]
return lst
#--------------------------------------
</code></pre>
<p>The result is:</p>
<pre><code>#--------------------------------------
>>> merge(lsts)
>>> [0, 1, 3, 4, 5, 10, 11, 16], [8, 2]]
#--------------------------------------
</code></pre>
<p><strong>Update 2:</strong>
To my experience the code given by <strong>Niklas Baumstark</strong> below showed to be a bit faster for the simple cases. Not tested the method given by "Hooked" yet, since it is completely different approach (by the way it seems interesting).
The testing procedure for all of these could be really hard or impossible to be ensured of the results. The real data set I will use is so large and complex, so it is impossible to trace any error just by repeating. That is I need to be 100% satisfied of the reliability of the method before pushing it in its place within a large code as a module. Simply for now <strong>Niklas</strong>'s method is faster and the answer for simple sets is correct of course.<br>
<strong>However how can I be sure that it works well for real large data set?</strong> Since I will not be able to trace the errors visually!</p>
<p><strong>Update 3:</strong>
Note that reliability of the method is much more important than speed for this problem. I will be hopefully able to translate the Python code to Fortran for the maximum performance finally.</p>
<p><strong>Update 4:</strong><br>
There are many interesting points in this post and generously given answers, constructive comments. I would recommend reading all thoroughly. Please accept my appreciation for the development of the question, amazing answers and constructive comments and discussion.</p> | 0 |

<p>Somehow that script is not executed at all. I don't see any of the strings that should be echoed. I am familiar with Unix commandline in Linux and Mac OS X, but I have no idea how it works under Windows. Any suggestions please?</p>
<p>EDIT: Okay, my mistake... this script is executed, but I don't fully understand what it does. I was hoping to prevent being asked for passphrase every time I push to remote repo. As it stands now I'm still asked every time.</p> | 0 |
Reset git settings | <p>When I try downloading <a href="https://git01.codeplex.com/casablanca" rel="noreferrer">this</a> git repo I keep getting <code>error: RPC failed; result=56, HTTP code = 200</code> and I think this is because I messed up some settings (i was playing about with <code>--config</code> and <code>--bare</code> today)</p>
<p>Is there a way how I can reset my git configuration to the factory settings?</p>
<p>If it helps I am on a Mac.</p> | 0 |
How do I retrieve output from Multiprocessing in Python? | <p>So, I'm trying to speed up one routine by using the Multiprocessing module in Python. I want to be able to read several .csv files by splitting the job among several cores, for that I have:</p>
<pre><code>def csvreader(string):
from numpy import genfromtxt;
time,signal=np.genfromtxt(string, delimiter=',',unpack="true")
return time,signal
</code></pre>
<p>Then I call this function by saying:</p>
<pre><code>if __name__ == '__main__':
for i in range(0,2):
p = multiprocessing.Process(target=CSVReader.csvreader, args=(string_array[i],))
p.start()
</code></pre>
<p>The thing is that this doesn't store any output. I have read all the forums online and seen that there might be a way with multiprocessing.queue but I don't understand it quite well.
Is there any simple and straightforward method?</p> | 0 |
How can I display a dialog above the keyboard | <p>I'm a newbie with android, I write an application which using the Dialog to display data when user select on one thing. This is how the dialog looks:</p>
<p><a href="https://docs.google.com/file/d/0B3NUAgD0tB0YOS16azFCWXdSVVE/edit" rel="noreferrer">https://docs.google.com/file/d/0B3NUAgD0tB0YOS16azFCWXdSVVE/edit</a></p>
<p>But when I tap on the last EditText to enter some data, the dialog still shows, when I type the first character, the dialog scrolls down. The dialog stays behind the keyboard, with some parts totally obscured.</p>
<p>Could anyone tell me how to show the whole dialog above the soft keyboard? This is how I'd like it to look:</p>
<p><a href="https://docs.google.com/file/d/0B3NUAgD0tB0YOFVQYUF0U0JvOEk/edit" rel="noreferrer">https://docs.google.com/file/d/0B3NUAgD0tB0YOFVQYUF0U0JvOEk/edit</a></p>
