• Game Technologies: DirectX, XNA, XACT, etc. 2d display in direct3d

  I'm looking for some help in drawing a texture (or anything really) that is fixed to the screen. Like text in the sdk samples, you can move around in 3d but the text is fixed. My goal is to create a heads up display for a 3d fps. I just started learning direcx 9 abt 2.5 weeks ago but have the basics down - except this. If anyone could point me to a sample it would be great. Thanks in advance  oh btw i'm using c++ I've seen people using quads in 3d and setting the projection to orthonormal to create this effect. There is a good reason for this - it allows you to apply a vertex ...Show All

• Visual Basic ConnectionStrings in Class Libraries

  I have created a class library that has DataSets in it. When you configure a DataSet in Visual Studio 2005, the connection string goes in the app.config file: < connectionStrings > < add name = " AClassLibrary.My.MySettings.MyDBConnectionString " connectionString = " Data Source=.;Initial Catalog=Northwind;Integrated Security=True " /> </ connectionStrings > - fine, so in theory you can configure it at runtime. Except, of course, that this configuration setting must go in the host applications' web.config or app.config. However, if you copy the connection string above into the host config file, my class library ca ...Show All

• Visual C# regularexpressionvalidator - Does it allow look ahead?

  I have a regularexpressionvalidator which is using the following expression: ^\$ ( =[1-9])( :\d{7,10}|\d(\d{1,2}) ( (1)(,\d{3}){2}|(,\d{3}){2,3}))(\.\d{2}) $ It is supposed to check for a value between 1000000 and $9,999,999,999.00, with or without commas, $ or decimal. It works when I try it in a regular expression tester but won't work in the the validator. I am wondering if maybe the regularexpressionvalidator doesn't allow for look ahead. ...Show All

• .NET Development Increasing the runtime heap?

  Hi I've got an issue with OutOfMemory exceptions occuring in an application. I know the gen 0 heap size is based on the L2 cache of the CPU running the system, but even when I try to run my process on a system that has a megabyte of it, it gets the exception not even halfway in. Normally, I'd just take it for granted that I was wasting too much memory too quickly, but the problem is - I need all of the memory I'm trying to allocate, and I need it all right away. Even if I insert GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect() and a Thread.Sleep(500); into my allocation loop, not enough is being collected for me to continue on. S ...Show All

• Visual C# How this code work(C# 2.0)? It shouldn't!

  What makes you think that, there is no ambiguity possible, the compiler can directly deduce the best function member to call, 3 is an int parameter and there is a non-generic method F1 taking an int as argument, non-generics takes precedence over generic parameters, overload resolution solved, point. make your call g1a.F1(3L); and you will get a compiler error, as now there aint no method taking a long. change it to G1 g1a = new G1 (); g1a.F1(3L); And the first method will be called. Willy This works because the design has changed.  According to a newsgroup post back in early april by Rick Byers (msft):, ...Show All
