DOCUMENT:Q140585 06-MAY-2001 [visualc] TITLE :PRB: Resizing CPropertySheet in OnInitDialog Does Not Work PRODUCT :Microsoft C Compiler PROD/VER:winnt:4.0 OPER/SYS: KEYWORDS:kbcode kbMFC kbPropSheet KbUIDesign kbVC400 kbGrpDSMFCATL ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - The Microsoft Foundation Classes (MFC), used with: - Microsoft Visual C++, 32-bit Editions, version 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== If you create a class derived from CPropertySheet and use ClassWizard to add a handler for OnInitDialog(), the TODO comment will be added before the call to CPropertySheet::OnInitDialog(). If you replace the comment with calls to MoveWindow() or SetWindowPos() to resize the sheet, this will not work. Also, GetWindowRect() or GetClientRect() will not return the correct information if called before OnInitDialog(). This is the code generated by ClassWizard: BOOL CMySheet::OnInitDialog() { // TODO: Add your specialized code here and/or call the base class return CPropertySheet::OnInitDialog(); } CAUSE ===== CPropertySheet::OnInitDialog causes the CPropertySheet to resize. Therefore, any call to MoveWindow() or SetWindowPos() has no effect if it comes before CPropertySheet::OnInitDialog(). RESOLUTION ========== Call CPropertySheet::OnInitDialog() first, before resizing the sheet, as in the following code. Sample Code ----------- // This code shows how to resize a modeless CPropertySheet and // add a button. // CMySheet is derived from CPropertySheet BOOL CMySheet::OnInitDialog() { CPropertySheet::OnInitDialog(); RECT rc; GetWindowRect (&rc); // Increase the height of the CPropertySheet by 30 rc.bottom += 30; // Increase the width of CPropertySheet by 50 rc.right +=50; // Resize the CPropertySheet MoveWindow (rc.left, rc.top, rc.right-rc.left, rc.bottom-rc.top); // Convert to client coordinates ScreenToClient (&rc); // m_Button is of type CButton and is a member of CMySheet m_Button.Create ("&MyButton", WS_CHILD | WS_VISIBLE | WS_TABSTOP, CRect (5, rc.bottom-30, 80, rc.bottom-5), this, IDC_MYBUTTON); return TRUE; } STATUS ====== This behavior is by design.
