What is the best way to draw skinnable "buttons" in a video game? | I'm looking for ideas on how to draw a skinnable "button" in a game application. If I use a fixed sprite non-vector image for the button background, then I can't size the button easily. If I write code to draw a resizable button (like Windows buttons are drawn), then the programmer has to get involved -- and it makes skinning difficult. Another option is to break the button into 9 smaller images (3x3) and stretch them all -- kindof like rounded corners are done in HTML. Is there another "easier" way? What's the best approach?

Productivity gains of using CASE tools for development | I was using a CASE called [MAGIC](http://www.magicsoftware.com/) for a system I'm developing, I've never used this kind of tool before and at first sight I liked, a month later I had a lot of the application generated, I felt very productive and ... I would say ... satisfied. In some way a felt uncomfortable, cause, there is no code and everything I was used to, but in the other hand I could speed up my developing. The fact is that eventually I returned to use C# because I find it more flexible to develop, I can make unit testing, use CVS, I have access to more resources and basically I had "all the control". I felt that this tool didn't give me confidence and I thought that later in the project I could not manage it due to its forced established rules of development. And also a lot of things like sending emails, using my own controls, and other things had their complication, it seemed that at some point it was not going to be as easy as initially I thought and as initially the product claims. This reminds me a very nice article called "[No Silver Bullet](http://www.virtualschool.edu/mon/SoftwareEngineering/BrooksNoSilverBullet.html)". This CASE had its advantages but on the other hand it doesn't have resources you can consult and actually the license and certification are very expensive. For me another dissapointing thing is that because of its simplistic approach for development I felt scared on first hand cause of my unexperience on these kind of tools and second cause I thought that if I continued using it maybe it would have turned to be a complex monster that I could not manage later in the project. I think it's good to use these kind of solutions to speed up things but I wonder, why aren't these programs as popular as VS.Net, J2EE, Ruby, Python, etc. if they claim to enhance productivity better than the tools I've pointed?

Building Standalone Applications in JavaScript | With the increased power of JavaScript frameworks like YUI, JQuery, and Prototype, and debugging tools like Firebug, doing an application entirely in browser-side JavaScript looks like a great way to make simple applications like puzzle games and specialized calculators. Is there any downside to this other than exposing your source code? How should you handle data storage for this kind of program? Edit: yes, Gears and cookies can be used for local storage, but you can't easily get access to files and other objects the user already has around. You also can't save data to a file for a user without having them invoke some browser feature like printing to PDF or saving page as a file.

Catching SQL Injection and other Malicious Web Requests | I am looking for a tool that can detect malicious requests (such as obvious SQL injection gets or posts) and will immediately ban the IP address of the requester/add to a blacklist. I am aware that in an ideal world our code should be able to handle such requests and treat them accordingly, but there is a lot of value in such a tool even when the site is safe from these kinds of attacks, as it can lead to saving bandwidth, preventing bloat of analytics, etc. Ideally, I'm looking for a cross-platform (`LAMP/.NET`) solution that sits at a higher level than the technology stack; perhaps at the web-server or hardware level. I'm not sure if this exists, though. Either way, I'd like to hear the community's feedback so that I can see what my options might be with regard to implementation and approach.

MOSS SSP Issue - Failed database logons from deleted SSP | We've been having some issues with a SharePoint instance in a test environment. Thankfully this is not production ;) The problems started when the disk with the SQL Server databases and search index ran out of space. Following this, the search service would not run and search settings in the SSP were not accessible. Reclaiming the disk space did not resolve the issue. So rather than restoring the VM, we decided to try to fix the issue. We created a new SSP and changed the association of all services to the new SSP. The old SSP and it's databases were then deleted. Search results for PDF files are no longer appearing, but the search works fine otherwise. MySites also works OK. Following the implementation of this change, these problems occur: > > 1) An audit failure message started appearing in the application event log, for 'DOMAIN\SPMOSSSvc' which is the MOSS farm account. > > > ``` Event Type: Failure Audit Event Source: MSSQLSERVER Event Category: (4) Event ID: 18456 Date: 8/5/2008 Time: 3:55:19 PM User: DOMAIN\SPMOSSSvc Computer: dastest01 Description: Login failed for user 'DOMAIN\SPMOSSSvc'.

Inheritance and Polymorphism - Ease of use vs Purity | In a project our team is using object lists to perform mass operations on sets of data that should all be processed in a similar way. In particular, different objects would ideally act the same, which would be very easily achieved with polymorphism. The problem I have with it is that inheritance implies the *is a* relationship, rather than the *has a* relationship. For example, several objects *have a* damage counter, but to make this easy to use in an object list, polymorphism could be used - except that would imply an *is a* relationship which wouldn't be true. (A person *is not a* damage counter.) The only solution I can think of is to have a member of the class return the proper object type when implicitly casted instead of relying on inheritance. Would it be better to forgo the *is a* / *has a* ideal in exchange for ease of programming? Edit: To be more specific, I am using C++, so using polymorphism would allow the different objects to "act the same" in the sense that the derived classes could reside within a single list and be operated upon by a virtual function of the base class. The use of an interface (or imitating them via inheritance) seems like a solution I would be willing to use.

Upgrading SQL Server 6.5 | Yes, I know. The existence of a running copy of `SQL Server 6.5` in 2008 is absurd. That stipulated, what is the best way to migrate from `6.5` to `2005`? Is there any direct path? Most of the documentation I've found deals with upgrading `6.5` to `7`. Should I forget about the native `SQL Server` upgrade utilities, script out all of the objects and data, and try to recreate from scratch? I was going to attempt the upgrade this weekend, but server issues pushed it back till next. So, any ideas would be welcomed during the course of the week. *Update. This is how I ended up doing it:* * Back up the database in question and Master on `6.5`. * Execute `SQL Server 2000`'s `instcat.sql` against `6.5`'s Master. This allows `SQL Server 2000`'s OLEDB provider to connect to `6.5`. * Use `SQL Server 2000`'s standalone `"Import and Export Data"` to create a DTS package, using `OLEDB` to connect to 6.5. This successfully copied all `6.5`'s tables to a new `2005` database (also using `OLEDB`). * Use `6.5`'s Enterprise Manager to script out all of the database's indexes and triggers to a .sql file. * Execute that .sql file against the new copy of the database, in 2005's Management Studio. * Use 6.5's Enterprise Manager to script out all of the stored procedures. * Execute that `.sql` file against the `2005` database. Several dozen sprocs had issues making them incompatible with `2005`. Mainly `non-ANSI joins` and `quoted identifier issues`. * Corrected all of those issues and re-executed the `.sql` file. * Recreated the `6.5`'s logins in `2005` and gave them appropriate permissions. There was a bit of rinse/repeat when correcting the stored procedures (there were hundreds of them to correct), but the upgrade went great otherwise. Being able to use Management Studio instead of `Query Analyzer` and `Enterprise Manager 6.5` is such an amazing difference. A few report queries that took 20-30 seconds on the `6.5 database` are now running in 1-2 seconds, without any modification, new indexes, or anything. I didn't expect that kind of immediate improvement.

Visual Studio 2008 Window layout annoyance | I'm having a weird issue with Visual Studio 2008. Every time I fire it up, the solution explorer is about an inch wide.

C# 3.0 auto-properties — useful or not? | *Note: This was posted when I was starting out C#. With 2014 knowledge, I can truly say that auto-properties are among the best things that ever happened to the C# language.* I am used to create my properties in C# using a private and a public field: ``` private string title; public string Title { get { return title; } set { title = value; } } ``` Now, with [.NET](http://en.wikipedia.org/wiki/.NET_Framework) 3.0, we got auto-properties: ``` public string Title { get; set; } ``` I know this is more a philosophical/subjective questions, but is there any reason to use these auto-properties except from saving five lines of code for each field? My personal gripe is that those properties are hiding stuff from me, and I am not a big fan of black magic. In fact, the hidden private field does not even show up in the debugger, which is OK given the fact that the get/set functions do nothing. But when I want to actually implement some getter/setter logic, I have to use the private/public pair anyway. I see the benefit that I save a lot of code (one vs six lines) without losing the ability to change the getter/setter logic later, but then again I can already do that by simply declaring a public field "Public string Title" without the need of the { get; set; } block, thus even saving more code. So, what am I missing here? Why would anyone actually want to use auto-properties?

Printing from a .NET Service | I am working on a project right now that involves receiving a message from another application, formatting the contents of that message, and sending it to a printer. The technology of choice is C# windows service. The output could be called a report, I suppose, but a reporting engine is not necessary. A simple templating engine, like StringTemplate, or even XSLT outputting HTML would be fine. The problem I'm having is finding a free way to print this kind of output from a service. Since it *seems* that it will work, I'm working on a prototype using Microsoft's RDLC, populating a local report and then rendering it as an image to a memory stream, which I will then print. Issues with that are: * Multi-page printing will be a big headache. * Still have to use PrintDocument to print the memory stream, which is unsupported in a Windows Service (though it may work - haven't gotten that far with the prototype yet) * If the data coming across changes, I have to change the dataset and the class that the data is being deserialized into. bad bad bad. Has anyone had to do anything remotely like this? Any advice? I already posted a question about printing HTML without user input, and after wasting about 3 days on that, I have come to the conclusion that it cannot be done, at least not with any freely available tool. All help is appreciated. EDIT: We are on version 2.0 of the .NET framework.

If you have a Java application that is consuming CPU when it isn't doing anything, how do you determine what it is doing? | I am calling a vendor's Java API, and on some servers it appears that the JVM goes into a low priority polling loop after logging into the API (CPU at 100% usage). The same app on other servers does not exhibit this behavior. This happens on WebSphere and Tomcat. The environment is tricky to set up so it is difficult to try to do something like profiling within Eclipse. Is there a way to profile (or some other method of inspecting) an existing Java app running in Tomcat to find out what methods are being executed while it's in this spinwait kind of state? The app is only executing one method when it gets in this state (vendor's method). Vendor can't replicate the behavior (of course). --- Update: Using JConsole I was able to determine who was running and what they were doing. It took me a few hours to then figure out why it was doing it. The problem ended up being that the vendor's API jar that was being used did not match exactly to the the database configuration that it was using. It was defaulting to having tracing and performance monitoring enabled on the servers that had the slight mis-match in configuration. I used a different jar and all is well. So thanks, Joshua, for your answer. JConsole was extremely easy to setup and use to monitor an existing application. @Cringe - I did some experimenting with some of the options you suggested. I had some problems with getting JProfiler set up, it looks good (but pricey). Going forward I went ahead and added the Eclipse Profiler plugin and I'll be looking over the different open source profilers to compare functionality.

How to return a page of results from SQL? | Many applications have grids that display data from a database table one page at a time. Many of them also let the user pick the number of records per page, sort by any column, and navigate back and forth through the results. What's a good algorithm to implement this pattern without bringing the entire table to the client and then filtering the data on the client. How do you bring just the records you want to display to the user? Does LINQ simplify the solution?

Fonts on the Web | The collection of fonts available to a web developer is depressingly limited. I remember reading long ago about TrueDoc, as a way of shipping fonts alongside a website - but it seems to have languished. Has anybody used this, or something similar? Is it supported by enough browsers? Am I missing a good solution? Note that a responsible web developer does not use fonts that are only available on Windows (and *especially* ones that are only available on Vista), nor do they use a technology that isn't supported by at least the majority of browsers. --- **Update:** As several people have pointed out, there's nothing wrong with providing a list of fallback fonts for people who don't have the specific font you use. I do in fact always do this, and didn't mean to suggest that this was wrong. While my question was badly phrased, what I meant was that a designer should not make too many assumptions about what the client will have available. You should plan for how all users will see your site, not just for people using your own preferred setup.

HowTo Disable WebBrowser 'Click Sound' in your app only | The 'click sound' in question is actually a system wide preference, so I only want it to be disabled when my application has focus and then re-enable when the application closes/loses focus. Originally, I wanted to ask this question here on stackoverflow, but I was not yet in the beta. So, after googling for the answer and finding only a little bit of information on it I came up with the following and decided to post it here now that I'm in the beta. ``` using System; using Microsoft.Win32; namespace HowTo { class WebClickSound { /// <summary> /// Enables or disables the web browser navigating click sound. /// </summary> public static bool Enabled { get { RegistryKey key = Registry.CurrentUser.OpenSubKey(@"AppEvents\Schemes\Apps\Explorer\Navigating\.Current"); string keyValue = (string)key.GetValue(null); return String.IsNullOrEmpty(keyValue) == false && keyValue != "\"\""; } set { string keyValue; if (value) { keyValue = "%SystemRoot%\\Media\\"; if (Environment.OSVersion.Version.Major == 5 && Environment.OSVersion.Version.Minor > 0) { // XP keyValue += "Windows XP Start.wav"; } else if (Environment.OSVersion.Version.Major == 6) { // Vista keyValue += "Windows Navigation Start.wav"; } else { // Don't know the file name so I won't be able to re-enable it return; } } else { keyValue = "\"\""; } // Open and set the key that points to the file RegistryKey key = Registry.CurrentUser.OpenSubKey(@"AppEvents\Schemes\Apps\Explorer\Navigating\.Current", true); key.SetValue(null, keyValue, RegistryValueKind.ExpandString); isEnabled = value; } } } } ``` Then in the main form we use the above code in these 3 events: * Activated * Deactivated * FormClosing ``` private void Form1_Activated(object sender, EventArgs e) { // Disable the sound when the program has focus WebClickSound.Enabled = false; } private void Form1_Deactivate(object sender, EventArgs e) { // Enable the sound when the program is out of focus WebClickSound.Enabled = true; } private void Form1_FormClosing(object sender, FormClosingEventArgs e) { // Enable the sound on app exit WebClickSound.Enabled = true; } ``` The one problem I see currently is if the program crashes they won't have the click sound until they re-launch my application, but they wouldn't know to do that. What do you guys think? Is this a good solution? What improvements can be made?

Using Visual Studio to develop for C++ for Unix | Does anyone have battle stories to share trying to use Visual Studio to develop applications for Unix? And I'm not talking using .NET with a Mono or Wine virtual platform running beneath. Our company has about 20 developers all running Windows XP/Vista and developing primarily for Linux & Solaris. Until recently we all logged into a main Linux server and modified/built code the good old fashioned way: Emacs, Vi, dtpad - take your pick. Then someone said, "hey - we're living in the Dark Ages, we should be using an IDE". So we tried out a few and decided that Visual Studio was the only one that would meet our performance needs (yes, I'm sure that IDE X is a very nice IDE, but we chose VS). The problem is, how do you setup your environment to have the files available locally to VS, but also available to a build server? We settled with writing a Visual Studio plugin - it writes our files locally and to the build server whenever we hit "Save" and we have a bit fat "sync" button that we can push when our files change on the server side (for when we update to the latest files from our source control server). The plugin also uses Visual Studio's external build system feature that ultimately just ssh's into the build server and calls our local "make" utility (which is Boost Build v2 - has great dependency checking, but is *really* slow to start as a result i.e. 30-60 seconds to begin). The results are piped back into Visual Studio so the developer can click on the error and be taken to the appropriate line of code (quite slick actually). The build server uses GCC and cross-compiles all of our Solaris builds. But even after we've done all this, I can't help but sigh whenever I start to write code in Visual Studio. I click a file, start typing, and VS chugs to catch up with me. Is there anything more annoying than having to stop and wait for your tools? Are the benefits worth the frustration? Thoughts, stories, help?

Is there a way to make a constructor only visible to a parent class in C#? | I have a collection of classes that inherit from an abstract class I created. I'd like to use the abstract class as a factory for creating instances of concrete implementations of my abstract class. Is there any way to hide a constructor from all code except a parent class. I'd like to do this basically ``` public abstract class AbstractClass { public static AbstractClass MakeAbstractClass(string args) { if (args == "a") return new ConcreteClassA(); if (args == "b") return new ConcreteClassB(); } } public class ConcreteClassA : AbstractClass { } public class ConcreteClassB : AbstractClass { } ``` But I want to prevent anyone from directly instantiating the 2 concrete classes. I want to ensure that only the MakeAbstractClass() method can instantiate the base classes. Is there any way to do this? **UPDATE** I don't need to access any specific methods of ConcreteClassA or B from outside of the Abstract class. I only need the public methods my Abstract class provides. I don't really need to prevent the Concrete classes from being instantiated, I'm just trying to avoid it since they provide no new public interfaces, just different implementations of some very specific things internal to the abstract class. To me, the simplest solution is to [make child classes as samjudson mentioned](https://stackoverflow.com/questions/20185/is-there-a-way-to-make-a-constructor-only-visible-to-a-parent-class-in-c#20200). I'd like to avoid this however since it would make my abstract class' file a lot bigger than I'd like it to be. I'd rather keep classes split out over a few files for organization. I guess there's no easy solution to this...

LINQ to SQL strings to enums | LINQ to SQL allows table mappings to automatically convert back and forth to Enums by specifying the type for the column - this works for strings or integers. Is there a way to make the conversion case insensitive or add a custom mapping class or extenstion method into the mix so that I can specify what the string should look like in more detail. Reasons for doing so might be in order to supply a nicer naming convention inside some new funky C# code in a system where the data schema is already set (and is being relied upon by some legacy apps) so the actual text in the database can't be changed.

Capture MouseDown event for .NET TextBox | Is there any way to capture the MouseDown even from the .NET 2.0 TextBox control? I know the inherited Control class has the event, but it's not exposed in TextBox. Is there a way to override the event handler? I also tried the OpenNETCF TextBox2 control which does have the MouseDown event exposed, but no matter what I do, it doesn't fire the handler. Any suggestions? --- > > What kind of crazy mobile device do > you have that has a mouse? :) > > > Yes, windows mobile does not have an actual mouse, but you are mistaken that Windows Mobile .NET do not support the Mouse events. A click or move on the screen is still considered a "Mouse" event. It was done this way so that code could port over from full Windows easily. And this is not a Windows Mobile specific issue. The TextBox control on Windows does not have native mouse events either. I just happened to be using Windows Mobile in this case. Edit: And on a side note...as Windows Mobile is built of the WindowsCE core which is often used for embedded desktop systems and Slim Terminal Services clients or "WinTerms" it has support for a hardware mouse and has for a long time. Most devices just don't have the ports to plug one in. --- > > According to the .Net Framework, the > MouseDown Event Handler on a TextBox > is supported. What happens when you > try to run the code? > > > Actually, that's only there because it inherits it from "Control", as does *every* other Form control. It is, however, overridden (and changed to private I believe) in the TextBox class. So it will not show up in IntelliSense in Visual Studio. However, you actually can write the code: ``` textBox1.MouseDown += new System.Windows.Forms.MouseEventHandler(this.textBox1_MouseDown); ``` and it will compile and run just fine, the only problem is that textBox1\_MouseDown() will not be fired when you tap the TextBox control. I assume this is because of the Event being overridden internally. I don't even want to change what's happening on the event internally, I just want to add my own event handler to that event so I can fire some custom code as you could with any other event.

We are strictly talking unit tests that need to be run as frequently as possible.* --- **Response roundup:** Thanks for the great responses so far. Most advice seems to be don't worry about the speed -- concentrate on quality and just selectively run them if they are too slow.

XPATHS and Default Namespaces | What is the story behind XPath and support for namespaces? Did XPath as a specification precede namespaces? If I have a document where elements have been given a default namespace: ``` <foo xmlns="uri" /> ``` It appears as though some of the XPath processor libraries won't recognize `//foo` because of the namespace whereas others will. The option my team has thought about is to add a namespace prefix using regular expressions to the XPath (you can add a namespace prefix via XmlNameTable) but this seems brittle since XPath is such a flexible language when it comes to node tests. Is there a standard that applies to this? My approach is a bit hackish but it seems to work fine; I remove the `xmlns` declaration with a search/replace and then apply XPath. ``` string readyForXpath = Regex.Replace(xmldocument, "xmlns=\".+\"", String.Empty ); ``` Is that a fair approach or has anyone solved this differently?

Center text output from Graphics.DrawString() | I'm using the .NETCF (Windows Mobile) `Graphics` class and the `DrawString()` method to render a single character to the screen. The problem is that I can't seem to get it centred properly. No matter what I set for the Y coordinate of the location of the string render, it always comes out lower than that and the larger the text size the greater the Y offset. For example, at text size 12, the offset is about 4, but at 32 the offset is about 10. I want the character to vertically take up most of the rectangle it's being drawn in and be centred horizontally. Here's my basic code. `this` is referencing the user control it's being drawn in. ``` Graphics g = this.CreateGraphics(); float padx = ((float)this.Size.Width) * (0.05F); float pady = ((float)this.Size.Height) * (0.05F); float width = ((float)this.Size.Width) - 2 * padx; float height = ((float)this.Size.Height) - 2 * pady; float emSize = height; g.DrawString(letter, new Font(FontFamily.GenericSansSerif, emSize, FontStyle.Regular), new SolidBrush(Color.Black), padx, pady); ``` Yes, I know there is the label control that I could use instead and set the centring with that, but I actually do need to do this manually with the `Graphics` class.

I would really like to avoid using cursors to iterate on the list of users (but that's my fall back option). I'm using SQL Server 2005. **Edit: @Lee:** Unfortunately the InStage1 = 1 was a simplification.

Why do we need entity objects? | I really need to see some honest, thoughtful debate on the merits of the currently accepted ***enterprise application*** design paradigm. I am not convinced that entity objects should exist. By entity objects I mean the typical things we tend to build for our applications, like "Person", "Account", "Order", etc. My current design philosophy is this: * All database access must be accomplished via stored procedures. * Whenever you need data, call a stored procedure and iterate over a SqlDataReader or the rows in a DataTable (Note: I have also built enterprise applications with Java EE, java folks please substitute the equvalent for my .NET examples) I am not anti-OO. I write lots of classes for different purposes, just not entities. I will admit that a large portion of the classes I write are static helper classes. I am not building toys. I'm talking about large, high volume transactional applications deployed across multiple machines. Web applications, windows services, web services, b2b interaction, you name it. I have used OR Mappers. I have written a few. I have used the Java EE stack, CSLA, and a few other equivalents. I have not only used them but actively developed and maintained these applications in production environments. I have come to the battle-tested conclusion that entity objects are getting in our way, and our lives would be *so* much easier without them. Consider this simple example: you get a support call about a certain page in your application that is not working correctly, maybe one of the fields is not being persisted like it should be. With my model, the developer assigned to find the problem opens *exactly 3 files*. An ASPX, an ASPX.CS and a SQL file with the stored procedure. The problem, which might be a missing parameter to the stored procedure call, takes minutes to solve. But with any entity model, you will invariably fire up the debugger, start stepping through code, and you may end up with 15-20 files open in Visual Studio. By the time you step down to the bottom of the stack, you forgot where you started. We can only keep so many things in our heads at one time. Software is incredibly complex without adding any unnecessary layers. Development complexity and troubleshooting are just one side of my gripe. Now let's talk about scalability. Do developers realize that each and every time they write or modify any code that interacts with the database, they need to do a throrough analysis of the exact impact on the database? And not just the development copy, I mean a mimic of production, so you can see that the additional column you now require for your object just invalidated the current query plan and a report that was running in 1 second will now take 2 minutes, just because you added a single column to the select list? And it turns out that the index you now require is so big that the DBA is going to have to modify the physical layout of your files? If you let people get too far away from the physical data store with an abstraction, they will create havoc with an application that needs to scale. I am not a zealot. I can be convinced if I am wrong, and maybe I am, since there is such a strong push towards Linq to Sql, ADO.NET EF, Hibernate, Java EE, etc. Please think through your responses, if I am missing something I really want to know what it is, and why I should change my thinking. ***[Edit]*** It looks like this question is suddenly active again, so now that we have the new comment feature I have commented directly on several answers. Thanks for the replies, I think this is a healthy discussion. I probably should have been more clear that I am talking about enterprise applications. I really can't comment on, say, a game that's running on someone's desktop, or a mobile app. One thing I have to put up here at the top in response to several similar answers: orthogonality and separation of concerns often get cited as reasons to go entity/ORM. Stored procedures, to me, are the best example of separation of concerns that I can think of. If you disallow all other access to the database, other than via stored procedures, you could in theory redesign your entire data model and not break any code, so long as you maintained the inputs and outputs of the stored procedures. They are a perfect example of programming by contract (just so long as you avoid "select \*" and document the result sets). Ask someone who's been in the industry for a long time and has worked with long-lived applications: how many application and UI layers have come and gone while a database has lived on? How hard is it to tune and refactor a database when there are 4 or 5 different persistence layers generating SQL to get at the data? You can't change anything! ORMs or any code that generates SQL ***lock your database in stone***.

Automating WSDL.exe in a Custom Build | I have a web application written in C# that consumes several internal web services. We have a development tier, a testing tier, and a production tier. Also, we use the `WSDL.exe` command to generate a `Proxies.cs` file for a given tier's web services. When we are ready to deploy our code up the stack from development to test or test to production, we need to run the `WSDL.exe` command to point to the appropriate version of the web services. Is there a generally accepted way to automate this?

How to encourage someone to learn programming? | I have a friend that has a little bit of a holiday coming up and they want ideas on what they should do during the holiday, I plan to suggest programming to them, what are the pros and cons that I need to mention? I'll add to the list below as people reply, I apologise if I duplicate any entries. **Pros I have so far** 1. Minimal money requirement (they already have a computer) 2. Will help them to think in new ways 3. (Rob Cooper) Great challenge, every day really is a fresh challenge in some way, shape or form. Not many jobs can truly offer that. 4. (Rob Cooper) I like the way it makes me think.. I look at EVERYTHING more logically as my skills improve.. This helps with general living as well as programming. 5. (Rob Cooper) Money is/can be pretty good. 6. (Rob Cooper) Its a pretty portable trade.. With collaboration tech as it is, you can pretty much work anywhere in the world so long as you have an Internet connection. 7. (Rob Cooper) It's an exciting industry to work in, theres massive amounts of tech to work and play with! 8. (Quarrelsome) Jetpacks. Programming is Technology and the more time we spend with technology the closer we get to having Jetpacks. (*Teifion: This is a really cool analogy!*) 9. (Saj) Profitable way of Exercising Brain Muscles. 10. (Saj) It makes you look brilliant to some audience. 11. (Saj) Makes you tech-smart. 12. (Saj) Makes you eligible to the future world. 13. (Saj) It's easy, fun, not in a math way.. 14. (kiwiBastard) If the person likes problem solving then programming is no better example. 15. (kiwiBastard) Brilliant sense of achivement when you can interact with something you have designed and coded 16. (kiwiBastard) Great way to meet chicks/chaps - erm, maybe not that one (*Teifion: I dunno where you do programming but I want to come visit some time*) 17. (epatel) Learning how to program is like learning spell casting at Hogwarts . The computer will be your servant forever... **Cons I have so far** 1. Can be frustrating when it's not working 2. Not physical exercise 3. (Rob Cooper) There are a lot of people doing it just for the money. They have no love for the craft and just appear lazy, annoying and sometimes it can really grind my gears seeing an industry and workforce I enjoy so much being diluted with crap. Which can often reflect badly on all of us. 4. (Rob Cooper) Not so sure about the initial cost.. Yeah you can get started with Java or something at low cost, but for me, locally, the vast demand is for .NET developers, which can be costly getting up and running with. However, this is rapidly/has not becoming the case with the amount of work put in by MS with releasing pretty damn good Express editions of their main development product line. 5. (Rob Cooper) Its a lifelong career.. I truly feel you never really become a "master" by nature of the industry, you stop for 1-2 years. You're behind the times.. Some people do not like the pace. 6. (Rob Cooper) Some geeks can be hard to work with.. While I think the general geek movement is really changing for the better, you will always have the classic "I am more intelligent than you" geeks that can really just be a pain in the ass for all! 7. (Saj) Can cause virtual damage. 8. (Saj) Can make one throw their computer away. 9. (Saj) Can make one only virtually available to the world.

Telligent's Community Server | The company I work for is wanting to add blog functionality to our website and they were looking to spend an awful amount of money to have some crap being built on top of a CMS they purchased (sitecore). I pointed them to Telligent's Community Server and we had a sales like meeting today to get the Marketing folks on board. My question is if anyone has had issues working with Community Server, skinning it and extending it? I wanted to explain a bit why I am thinking Community Server, the company is wanting multiple blogs with multiple authors. I want to be out of the admin part of this as much as possible and didn't think there were too many engines that having multiple blogs didn't mean db work. I also like the other functionality that Community Server provides and think the company will find it useful, particularly the media section as right now we have some really shotty way of dealing with whitepapers and stuff. edit: We are actually using the Sitecore blog module for a single blog on our intranet (which is actually what the CMS is serving). Some reasoning for why I don't like it for our public site are they are on different servers, it doesn't support multiple authors, there is no built in syndication, it is a little flimsy feeling to me from looking at the source and I personally think the other features of Community Server make its price tag worth it. another edit: Need to stick to .net software that run on sql server in my company's case, but I don't mind seeing recommendations for others. ExpressionEngine looks promising, will try it out on my personal box.

Which scripting language to support in an existing codebase? | I'm looking at adding scripting functionality to an existing codebase and am weighing up the pros/cons of various packages. Lua is probably the most obvious choice, but I was wondering if people have any other suggestions based on their experience. Scripts will be triggered upon certain events and may stay resident for a period of time. For example upon startup a script may define several options which the program presents to the user as a number of buttons. Upon selecting one of these buttons the program will notify the script where further events may occur. These are the only real requirements; 1. Must be a cross-platform library that is compilable from source 2. Scripts must be able to call registered code-side functions 3. Code must be able to call script-side functions 4. Be used within a C/C++ codebase.

How print Flex components in FireFox3? | Thanks to FireFox's buggy implementation of ActiveX components (it really should take an image of them when printing) Flex components (in our case charts) don't print in FX. They print fine in IE7, even IE6. We need these charts to print, but they also have dynamic content. I don't really want to draw them again as images when the user prints - the Flex component should do it.
