try using a better subject title. most people here are asking how to do things, so calling your post ''how do i?'' doesn''t attract the eye in the same way as ''going fullscreen'' would.

in answer to you question, I don''t know.

For the same reasons why it''s ''bad'' to make any other variable global. Encapsulation is ''good''. Not knowing who or what will access it, from where and in what fashion, is ''bad''.

I think you would succeed with

ShowWindow(hWnd, SW_MAXIMIZE)

As others have already said, global variables are generally
dangerous because you can''t control who can access them.

In other words, you will learn not to use globals after you first
spend some hours searching for who the hell is overwriting
that variable...

What are you talking about? Maximizing a window, or going fullscreen with DirectX, OpenGL, etc.?
How old are you?

I got this function from somewhere:

  
bool DDrawFullScreen()
{
	HRESULT ddrval;

	ddrval=DirectDrawCreate(NULL,&dDraw,NULL);
	if (ddrval!=DD_OK) return false;

	ddrval=dDraw->SetCooperativeLevel(hwnd,DDSCL_EXCLUSIVE|DDSCL_FULLSCREEN);
	if (ddrval!=DD_OK) return false;

	ddrval=dDraw->SetDisplayMode(scr_x, scr_y, 32);
	if (ddrval!=DD_OK ) return false;

	// Workaround for RIVA 128

	ddrval=dDraw->SetCooperativeLevel(hwnd,DDSCL_EXCLUSIVE|DDSCL_FULLSCREEN);
	if (ddrval != DD_OK) return false;

	return true;
}

dDraw is of type LPDIRECTDRAW, you should store it until you''re switching back to windows:

  
void DDShut()
{
  dDraw->Release();
  dDraw = NULL;
}
