return(0);
} break;
case WM_PAINT: // called when window needs painting
{

hdc = BeginPaint(hwnd,&ps);
EndPaint(hwnd,&ps);
return(0);
} break;

while(1)
{
if (PeekMessage(&msg,NULL,0,0,PM_REMOVE))
{
// test whether this is a quit
if (msg.message == WM_QUIT) break;
// translate accelrator keys
TranslateMessage(&msg);
// send the message to thw window proc
DispatchMessage(&msg);
} // end if
// main game processing goes here
} // end while
// return to Windows like this
return(msg.wParam);
} // end WinMain

Link to Gdi32.lib
RE: Need help with code by Reaper on 09-05-2005 at 03:36 PM
umm, how
RE: Need help with code by Stigmata on 09-05-2005 at 03:45 PM
#include <Gdi32.lib>
RE: Need help with code by Reaper on 09-05-2005 at 03:48 PM
Gdi32.lib: No such file or directory.
RE: Need help with code by Stigmata on 09-05-2005 at 03:50 PM

#pragma comment(lib, "gdi32.lib")

It's not a header

That'll work
Or, if you're using Visual C++6, open the Project Settings (Alt+F7), go to the Link tab, and add 'gdi32.lib' to the end of the list (for all configs btw).

nop dont work. its odd, without using gdi32.lib in visual c++it works. but dev c++ doesnt work with or without it in
RE: Need help with code by RaceProUK on 09-05-2005 at 08:25 PM
It works in VC++ because that automatically links to gdi32.lib - it's a default. And that #pragma is specific to C++ as well - other preprocessors will have different ways of linking.
I see Dev-C++ uses a port of GCC. In that case, you'll need to find the command line and add '-lgdi32' to it.
