HI I use (Microsoft FlexGrid Control, version 6.0) which is active x control . It’s very useful, but some member functions are unclear . Now I’m interested in how useing two functions and maybe they will be the keys of the rest functions . 1 – void AddItem(LPCTSTR Item, const VARIANT& index) to add new rwo BUT HOW??? 2 - long GetRowData(long index) to get data from specific row BUT HOW??? I put this qustion befor and one told me look for (MsFlxGrd.hlp) I tried to find it but there is no file like this Thank you very much … AHMAD ALWASHALI

Hi every one I use try and catch to initial some things or destroy when some thing wrong. It’s works fine ,but an debug assertion occurred when destroy window. My code like this : BOOL MyDlg::OnInitDialog() { m_dat = new CDaoDatabase; try { m_dat->Open("dat.mdb"); } catch (CDaoException* e){ delete m_dat; m_dat=NULL; e->ReportError(); e->Delete(); CDialog::OnCancel(); } } I hope for any one can help me to avoid that debug assertion and tell me more about it ... Thank you,,, AHMAD ALWASHALI

HI I’m confused between pointer to CWnd and handle also to CWnd .What’s the difference between handle and pointer in CWnd object .For example when I want to chat text color in text box control : HBRUSH CMyDlg::OnCtlColor(CDC*pDC,CWnd*pWnd,UINTCtlColor) { HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor); ////////////////////////////////////////////// CWnd* wnd=GetDlgItem(IDC_EDIT1); if(wnd==pWnd) // using pointers { pDC->SetTextColor(RGB(255,0,0)); } /////////////////////////////////////////////// return hbr; } this code doesn’t chang text color .But when I use handles like this example : HBRUSH CMyDlg::OnCtlColor(CDC*pDC,CWnd*pWnd,UINT nCtlColor) { HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor); //////////////////////////////////////////////// CWnd* wnd=GetDlgItem(IDC_EDIT1); if(wnd->m_hWnd==pWnd->m_hWnd) // using handles { pDC->SetTextColor(RGB(255,0,0)); } /////////////////////////////////////////////////// return hbr; } now this code do what I want to chang text color . Can any one tell me what difference between pointers and handles in CWnd objects ? Thank you … AHMAD ALWASHALI
