In my main.cpp I declare HWND hWnd; HINSTANCE hInstance; I get the instance and they window is made just fine. In a .h file declare externs to them. When I try to use them hWnd works fine but hInstance is always NULL. Any ideas? Thanks. InFerN0 Not all who wander are lost...

I take it you are saving the value of hInstance passed by WinMain in your global hInstance. Coz if you create your window from the winmain function directly (e.g. no function calls) you will use the passed hInstance fine only within winmain itself.

Remember: If you have your source file like this:


HWND hWnd;
HINSTANCE hInstance;

int APIENTRY
WinMain( HINSTANCE hInstance, HINSTANCE prevInstance, LPSTR lpCmdLine, int nCmdShow)
{
//Window creation code
}


WinMain''s hInstance is in scope, not the global hInstance. So the window creation will work fine, but if you try to access hInstance from another function, it will equal whatever value it was initialised to (e.g. NULL).

Waassaap!!

basically,

    HINSTANCE hInstance;int WINAPI WinMain(HINSTANCE hInstance,/*etc...*/){    hInstance = hInstance;}/////////////////////////////////////////HINSTANCE hInstance;int WINAPI WinMain(HINSTANCE hInst,/*etc...*/){    hInstance = hInst;    

in the first one, you''re simply assigning the hInstance from the parameter list to itself, because it''s in scope.. the second one will work fine..
