I have a dialog with an OCX control.

 

BOOL CMyDialog::OnInitDialog()

{

    SetFlag(xtResizeNoSizeIcon);

   CXTResizeDialog::OnInitDialog();

 

    SetResize(...);

    SetResize(IDC_OCX_CONTROL, ...);

   

    // This solves the problem:

    // CRect rect;

    // GetClientRect(rect);

    // int cx = rect.Width();

    // int cy = rect.Height();

    // SendMessage(WM_SIZE, SIZE_RESTORED, MAKELPARAM(cx, cy));

    return TRUE;

}

 

The OCX will not be sized properly until a WM_SIZE message is sent! What could be the cause?
