Center Dialog - Win32

I want a function in my InitDialog:

case WM_INITDIALOG:
 
     CenterDialog(hWndDlg);
     .
     .
     .

thing is... I don't know how.

I have played with system metric stuff, but no success.

Thanks!

You can do that like

void CenterWindow (HWND hwnd) {

      RECT rc;

      GetWindowRect(&rc);

      int nWidth = rc.right - rc.left;
      int nHeight = rc.bottom - rc.top;

      int X = ((int) GetSystemMetrics(SM_CXFULLSCREEN) - nWidth) /2;       // center window horizontally
    int Y = ((int) GetSystemMetrics(SM_CYFULLSCREEN) - nHeight) /2;      // and vertically


      MoveWindow(hwnd,X,Y,nWidth,nHeight,TRUE);
}

In case others are reading this, jkr's above comment works great! He made a type though:

change:

GetWindowRect(&rc);

to

 GetWindowRect(hwnd, &rc);

and you got a winner!

Thanks.
