I cannot run some Nehe''s applications. In some cases I received ERROR ''initialization failed'' after message: Would You Like to Run in Fullscreen mode YES/NO. I have Win 2000, Visual C++. What to do? May be someone will help me?

Debug the application and find the point where InitGL (or whatever) returns error.

Excuse my poor english!

-----------------------------------------------------------------
int WINAPI WinMain(.....) .....

......

if (MessageBox(NULL,"Would You Like To Run In Fullscreen Mode?", "Start FullScreen?",MB_YESNO|MB_ICONQUESTION)==IDNO)
{
fullscreen=FALSE;
}
// Create Our OpenGL Window
-----------------------------------------------------------------
APPLICATION RETURNS ERROR IN THIS PLACE:
-----------------------------------------------------------------
if (!CreateGLWindow("Lionel Brits & NeHe''s 3D World Tutorial",640,480,16,fullscreen))
{
return 0; // Quit If Window Was Not Created
}
while(!done)
............
-----------------------------------------------------------------

There''s lots of places CreateGLWindow can fail. Start the app from the debugger, choose to run it in windowed mode so it doesn''t overlap with your debugger, and set a breakpoint at the top of CreateGLWindow and step through it, and identify the line in that function that fails.

It is in:
----------------------------------------------------------------
BOOL CreateGLWindow(char* title, int width, int height, int bits, bool fullscreenflag)
........

in:

if (!InitGL()) {
KillGLWindow(); MessageBox(NULL,"Initialization Failed.","ERROR",MB_OK|MB_ICONEXCLAMATION);
return FALSE;
}
return TRUE;

where in int InitGL(GLvoid) the (!LoadGLTextures()) returns 0

after that there is message "Initialization Failed."

''lo,

if not, you should put the texture in a subdirectory "Data" in the directory where your .exe is.

./lessonXX.exe
./data/texture.bmp

scuse my english too.

It seems your LoadGLTextures function returns FALSE. So check the path of the texture(s) and check the LoadGLTextures function. The error also could be that u have only the exe (or the program) and you doesnt have the textures.
