• Game Technologies: DirectX, XNA, XACT, etc. Dream Build Play -- Rules Question

  My game I was going to enter into this contest is going to be based off the Spacewar starter kit, and use a huge amount of the code from it, but the game itself has almost nothing to do with Spacewar itself. It has nothing to do with space at all and the gameplay is totally different, but the codebase is still being used to develop it, as there is a lot of good code in there. The rules, however, are unclear as to whether this is acceptable... "The only requirement: Your game must be derived from the version of Spacewar that’s a part of XNA Game Studio Express. Use as much or as little of the Spacewar Starter Kit as you like. Just remember that the relationship to the Spacewar Starter Kit must be obvious to our judges ." ...Show All

• Visual C# Windows Service Problem

  Hello, I’m hoping someone at MS can help me. I’ve created a C# Windows Service project whose service main function instantiates a class library that spawns a new thread to create a new process with which to launch osk.exe (the Windows on-screen keyboard). The purpose for creating this service is to have the on-screen keyboard appear immediately after startup (before the login screen) on a system that will have no keyboard hardware. I had first built a test program (C# console application) to call the class library and test its functionality and it worked fine. Then I created the Service Project including its installer classes and installed the service with installutil. [Incidentally, all three projects—the class ...Show All

• .NET Development VB.NET client consuming AXIS web service - returning NULL

  Hi I have a web service hosted in WSAD developed in JAVA working on Axis 1.x platform. This web service receives an XML input and returns an XML output. I am trying to consume the web service from a .NET client. I tried to create the proxy class to invoke the web service referred to by above WSDL by using the wsdl.exe utility of .NET. I have written a seperate piece of code to invoke this proxy class and to invoke the web service in turn. Now, when I am invoking the web service from the caller class, I am passing the XML, but the return object is NULL. On inspection of the actual input to the web service, I found that the XML being passed to web service as SOAP body is getting distorted. The < of XML is getting converted to "&a ...Show All

• SQL Server Batch Jobs

  Is there a forum, documentation, link, or anything that talks about batch jobs, what they are, how to create them, run them, etc Basically, everything I need to know about batch jobs thx, Kat Hi Jens, I've been working with version 2000. Running a batch job to me is different for instance than running a proc (I think)... typically a batch job runs overnight because it takes a long time. I'm not sure what the definition of a batch job is. I believe it is a script that is run that takes a long time. Any ideas Kat ...Show All

• Visual Studio 2008 (Pre-release) Publish error

  I am trying to specify that Publish requires .NET 3.0 as a prerequisite but get an error compiling: Error 77 No 'PublicKey' or 'Hash' attribute specified for file 'NETFX30\Dotnetfx3_x64.exe' in item '.NET Framework 3.0'. I understand that publish was not allowed for the CTP's but I thought that was resolved now the framework is released. Thanks John Thanks Rob I intend to get a cert and that should handle the unknown publisher part. Currently the user is presented with four dialogs. One for the setup.exe app, where the dialog is the Run/Save dialog for download; similar one for the NET 3.0 framework but it is identified as from our web site, no NET 3.0 or 'Microsoft' info; the ...Show All

• .NET Development easy Regex.Replace() question

  I am using Regex.Replace(string, string, string) in this way: Regex.Replace("Gloria Estefan (1993) - Yesterday", "^Gloria Estefan (1993)", "Gloria Estefan"); So I want to change the artist name so it doesn't include the year anymore. The problem is that this doesn't work because of brackets! So this would work: Regex.Replace("Gloria Estefan - Yesterday", "^Gloria Estefan", "Beatles"); How can I make it work in all circumstances (brackets or no brackets).. I would prefer using Regex.Replace to something else, because it makes it easy to assure that text is replaced only if it appears at the beginning of the string (^). thank you..!

• Visual Studio Team System Error: No Pending Changes - But there are changes!

  Hello, Sometimes we're experiencing the following annoying behaviour with our TeamFoundation Server (RTM) and the TeamExplorer: A file was checked out and changed, and if I try to check in the changes ("Check in pending changes..."), TeamExplorer says "Error: No Pending Changes" and does nothing. This is not safely reproducible though. But it still gives our team a really bad feeling about migrating to TeamSystem (we're at it right now, and we're running into several small glitches). Whatever, right-clicking the directory and selecting "Refresh" solves the problem. Has anybody else experienced this problem and knows why or when it appears Best regards, Martin Hi, we have ...Show All

• Visual Basic Could someone point me in the right direction?

  Not even sure where to start. Need to subtract quantity from inventory table when quantity is added to invoice table. Start with transaction stored procedure Any guidance would be appreciated. Does the SQL db you are using support Triggers, you could use a trigger to update all the rows, similar to a stored procedure but is fired on an event such as INSERT or UPDATE to a table. Sample from MySQL: DELIMITER | CREATE TRIGGER testref BEFORE INSERT ON test1 FOR EACH ROW BEGIN INSERT INTO test2 SET a2 = NEW.a1; UPDATE test3 SET b3 = b3 + 1 WHERE a3 = NEW.a1; END; | DELIMITER ; In the above BEFORE can be AFTER, INSERT can be UPDATE or REPLACE and you can have multiple triggers.

• .NET Development Malware affecting JIT or CLR...

  I have a HP8230-notebook with VS2005 installed where I maintain and develop numerous .Net Framework 2.0 applications programmed in VB. As I use the same computer to browse various programmer's forums and also travelling websites I have found that from time to time "something" happens to my computer that suddenly and irrevocably slows down startup time for my managed applications when I browse on the Web. I suspect it is some kind of malware, but neither Norton Antiviris 2006 nor my installed antispywares report anything abnormal. Symtoms are: - increased startup time for my managed applications by a factor of 5-7 times, - increased application closedown time by same rate, - increased time to load child windows within the ...Show All

• Visual Studio Express Editions How can I make a non-.net application with visual c++?

  More specifically: How can I make a Form application without the .net framework and what decides the difference between wether or not a program requires .net framework to run In the Project Properties you can choose Common Language Runtime support. Set it to no and your exe will not depent on .Net Framework. It still might need the c/c++ runtime. See here: http://www.microsoft.com/downloads/details.aspx familyid=32BC1BEE-A3F9-4C13-9C99-220B62A191EE&displaylang=en To avoid this choose C/C++ - Code generation from the project properties. Choose Multi Threaded (/MT) to statically link the runtime and not depend on the runtime dlls. -- SvenC ...Show All

• Smart Device Development Databinding to Datagrid

  I have a group of items in a datatable (approx. 11,000). I'm trying to bind this datatable to a datagrid in my mobile app (using sql mobile 2005, vs.net 2005) but i keep getting the "storage memory is critically low error". I'm deploying to an emulator. What's the trick to loading large datasets in mobile applications. Do I need to adjust the projects settings somehow. I just don't get it. The trick it not to load large DataSets into memory as it would run out. Remember your application is limited to 32MB virtual memory (vs. 2 GB on desktop) and it’s not all free from the start. Consider using SqlCeResultSet instead - it would only load visible rows, all 10 or so of them. In this case, however, you’re running ...Show All

• .NET Development Referencing Assemblies Through Code

  How can I reference an assembly through my code, I don't think it can be part of a project, this is related to my previous thread about 3 days ago, but I prefer to keep different questions in different threads. Anyways, Upon running my game, it will build a .exe, from the contents of a .cfg file, I need the .exe that it outputs, to be able to reference my main Game, I need it to be able to change variables and stuff, they are mostly all set to public and what not... Two ways to do this. You could let your main form generate events, install event handlers when you load and initialize your dynamic assembly. Or have a class in your assembly implement an interface. ...Show All

• Visual Studio 2008 (Pre-release) Namespace 'var' could not be found...

  Am evaluating LinQ. I created a LinQ Windows Application using the LinQ Preview template without any problems. Would very much like to use it. I then tried to use LinQ in one of my existing projects. However I get the following error when using "var" when trying to compile var x = "string" ; The type or namespace name 'var' could not be found. (are you missing a using directive or an assembly reference) I think I have added all the LinQ using directives and references. Not that familiar with C#. Would appreciate any help.
