int WINAPI WinMain(don't know the exact params off the top of my head) or int main()

[Felipeb18]

What do u mean?

[B1ackAnge1]

instead of
int WINAPI Main(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nShowCmd)


use:

int WINAPI WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nShowCmd)

Ive already tried this.
But I think its something wrong with the header because any code that i put using windows.h is giving the same error
