How do you center a window?

What CW_ command do you use to make the window centered in the screen? Thanks.

Assuming you're using the Win32 API, the following function function might do the trick.

Code:

---

/*
 *  Centers a window in the screen.
 */
void CenterWindowInScreen( HWND hwnd )
{
  if ( !IsWindow(hwnd) ) return;

  RECT rcWindow;
  GetWindowRect(hwnd,&rcWindow);
  int width  = rcWindow.right - rcWindow.left;
  int height  = rcWindow.bottom - rcWindow.top;
  int centerX =( GetSystemMetrics(SM_CXSCREEN) - width)/2;
  int centerY =( GetSystemMetrics(SM_CYSCREEN) - height)/2;
  SetWindowPos(hwnd,HWND_TOP,centerX,centerY,0,0,
SWP_NOSIZE|SWP_NOZORDER);
}

Am I missing a header file or somthing?

My bad. It's a typo. Fixed.

Okay, thanks!
