The exception you get is probably about the hWnd being 0. From where are you calling this? What function?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Peter Weyzen Staff Engineer [SoonR Inc.](http://www.soonr.com)Thanks i call the function which to change CPropertypage's title,when i click the button in the CPropertypage(others)! Main.h
CPropertySheet m_sheet; CAboutDlg m_about;Main.cppBOOL COptionDlg::OnInitDialog() { ..... m_sheet.AddPage(&m_about); m_sheet.Create(this, WS_CHILD|WS_VISIBLE,WS_EX_CONTROLPARENT); m_sheet.SetWindowPos(NULL, 4, 4,25, 50, SWP_NOSIZE | SWP_NOZORDER | SWP_NOACTIVATE); .... }CAbout.cpp //the CAboutDlg was Createdvoid CAboutDlg::UpdateUI() { CPropertySheet* pSheet = (CPropertySheet*)GetParent();//Exception }hi -
Thanks for you reply! but SetWindowText is not ok!
CPropertySheet* pSheet = (CPropertySheet*)this->GetParent(); //Exception!!!//addition to the above code COptionDlg* dlg = (COptionDlg*)this->GetParentOwner(); TCHAR buf[MAX_PATH]; TC_ITEM TabCtrlItem;hi -
Just check if the CAboutDlg is derived from CDialog or CPropertyPage. It should be CPropertyPaeg and must have done CPropertyPage but I am just asking to check it once more. so we can think of other options. Regards Anil
