• Game Technologies: DirectX, XNA, XACT, etc. GeForce4 MX 4000: No vertex or pixel shader support

  It seems that 3D objects will not render for me. I get a black screen. I posted about this in an other thread but it really wasn't on topic. The spacewar demo does not render on this machine. I get a black screen with the overlay display visible. I have tried several of the demos posted here as well as the simple how to in the help file. None of these work. Someone suggested that my video card has no shader support. I did some checking and discovered that this card infact does not support programmable vertex and pixel shaders.

• Visual C++ Return value incorrect

  Hi, I've got a very weird thing in my program, const bool getRunning() const { Lock(); bool t = m_bRunning; Unlock(); return t;} Where m_bRunning == true; it returns false. ( lock and unlock handles the thread safety ) after the Unlock(), t contains true. but the return value is always false. even weirder, with code optimalisation on, the function isnt even reachable. it just skips it. //DEBUG 0041B5FE call Gameye::CApplicationInfo::getRunning (411677h) 0041B603 movzx ecx,al 0041B606 cmp ecx,1 ECX contains 205 after this.

• Silverlight (formerly WPF/E) Squeezing objects

• SQL Server SQL 2005 Server DDL Trigger Errors

  Greetings! I've been working on a SQL 2005 project, and have really been excited about the new DDL triggers. I managed to implement some database-level DDL triggers successfully. However, I keep getting an error when I try to create a server-level DDL trigger. For several of the event groups, I keep getting the following error: Msg 1082, Level 15, State 1, Procedure tr_Server_Audit_Security, Line 44 "DROP_SERVER_ROLE_MEMBER" does not support synchronous trigger registration. I can't figure this one out for the life of me. Here's a sample of the trigger I'm trying to create (BTW, this code works for database triggers, with some slight mods of course): create trigger tr_Server_Audit_Security on all server  for drop_server_role ...Show All

• Windows Forms Getting Error "The type name 'ClientCaseInfoControl' does not exist in the type 'ClientAdjuster.ClientAdjuster'"

  I have written my first user control in Visual Studio .NET 2005.

• Visual Basic Null Reference Exception

  I am having a problem with a multi-form application I am writing in VB .Net 2003. When I transition back from one form to my startup form, I get an intermittent Null Reference Exception. Sometimes it will work, moving back and forth from form to form with no problems for 15-20 minutes, and sometimes it will crash everytime. I have tried putting a try-catch block around the instantiation of the main form. It does not catch anything. The exception points to line 2 of the startup form, which reads: Public Class frmWelcome Not much to cause a problem there, I would have thought. I am attaching the code for bringing up the welcome screen in hopes that someone will see something I am not thinking of. Try Dim welcome As New frm ...Show All
