• Visual C++ Compiler bug?

  I get incorrect results when running this app built release. It should print "a=1, b=2" but in release it prints "a=1, b=1". Correct results is obtained if the  member function "function" is put into the cpp file so that the compiler can't inline it. Is this a known compiler bug I'm using  version 7.1.3088. (This is an artificial example to show the phenomenon) /Staffan main.h: #include <iostream> #include "test.h" using namespace std; void print(int a, int b){     cout<<"a= "<<a<<", b= "<<b<<endl; } void main(){     Test test;     print(test.funct ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Picking Problem

  To solve the problem that I exposed in the other threat, I'm making changes to the Directx 9.0 's pick example. I've Tried this to move the position of the mesh: D3DXMATRIX matTranslation; D3DXMatrixTranslation( &matTranslation, 0.0f, 1.0f, 0.0f ); m_pd3dDevice->SetTransform( D3DTS_WORLD, &matTranslation ); m_pObject->Render( m_pd3dDevice ); The problem is that when I call the pick function, it doesn't consider the new world coordinates and it calculates the intersection as if the mesh continues placed in the old world coordinates. How can I make the pick function calculate the intersection in the n ...Show All

• Visual Studio Team System Getting sharepoint back after Beta 3R migration

  OK, I've got Beta 3 Refresh up and running, but the sharepoint sites didn't take kindly to the database migration (apparently). When I try to open a project site, I get an error message: The virtual server that is referenced here is not in the config database. So, presumably something is amiss in the shareport configuration.  So far though, I'm having a hard time finding my way through the Sharepoint configuration site. So - Which virtual server is referenced here   Exactly which options in the WSS config screens would I use to find it/configure it In the WSS config screens, I see the following virtual servers: Default Web Site&nb ...Show All

• Visual Studio Express Editions Intellisense Elements Missing

  Hi all, Hopefully someone can help with this matter. I was attempting to bind a data table to a Checkedlistbox and display a selected field. As far as i was aware i could use the Datasource method to do this and then the displayMember method to set the filed i wish to display in the list. When looking through the intellisense options for the checkedlistbox I could find neither of these options. However, if i just typed them in and used them as normal, the code works fine. Does anyone know why the methods are missing from the intellisense and how (if possible) i can go about resolving this.   Many thanks in advance Gran ...Show All

• .NET Development Timeouts

  My application uses WebServices to transmit data to/from a Windows Form client. We are having a problem on several machines now, where communication with the web service just halts. After 10 - 15 minutes of usage, all web service call just start timing out. Using a trace, we see that no data is ever leaving the client machine and browsing the web still works fine. It seems that all the machines that exhibit this behavior have multiple NICs in them. But the puzzling thing is how the application just stops communicating. Also, if you close the app entirely and go back in it works fine for a period of time again. Any help ...Show All

• Visual Studio Team System Control Gallery Component in Visual Studio 2005 Team System?

  Hi, I have a simple question: does Visual Studio 2005 Team System contain a component like the Control Gallery on www.asp.net The thread: http://forums.asp.net/902167/ShowPost.aspx indicates that it does. But the descriptions here indicate that it mainly offers a Source Control system.
