Problem in getting size of a window

Hi,
I have a program with a picture control window. The line in the .rc file is as follows:
CONTROL "",IDC_CNTRLWIND,"Static",SS_WHITERECT | NOT WS_VISIBLE,69,0,215,149

Now I am trying to get the picture coordinates in my program using the following code:

Code:

---

CWnd * wnd = (CWnd *)GetDlgItem(IDC_CNTRLWIND_G3);
        CRect rect;
        wnd->GetWindowRect(&rect);

        XMIN = rect.left;
        YMIN = rect.top;
        XMAX = rect.right;
        YMAX = rect.bottom;

---

The problem is when I run the program the values that I get are:
XMIN = 392
YMIN = 123
XMAX = 715
YMAX = 365

which are not even close to the original coordinates for the window. I was wondering if anybody would have any idea what can cause such a problem. It should be noted that the dialog containing the picture control is used in a tab. Thanks

Try GetClientRect().

That does not help because I need the absolute coordinate since I want to do something special when the mouse button is clicked inside the rectangle.

The coordinates you specify in the resource script are not pixel values but dialog units and so will no correspond directly to the pixel coordinate values returned by GetClientRect. For more information regarding dialog units and their conversion, consult msdn for the following functions:

GetDialogBaseUnits.
MapDialogRect

I don't know if there are mfc analogues of these api functions.

If the problem is actually mapping screen to client coordinates and vice versa then ScreenToClient and ClientToScreen may be of some interest.
