:-O Please, Can anybody helps me ? I want to catch the CWnd pointer for the current dialog to use it in the CButton::Create() method. I tried to use "this" instead of CWnd in the OnButtonClick() its works ok, but when I tried to use "this" inside Custom Class (I created it) it doesn't work because the "this" pointer was pointing to the Current class.So " How can I get CWnd pointer for the current dialog ? " Thank you at all. Dr Abudawood

Thank you very much MR\ Mike I will test it in MFC. Dr Abudawood

:) Now I got the answer. after your help it was very easy as next: void CTestScrolDlg::AdjustColSize(int ColNo,CString s) { //Global variable Array width[ColNo] int Gab = 15; int size=m_ListControl.GetStringWidth(s)+Gab; if( width[ColNo] < size ) { m_ListControl.SetColumnWidth(ColNo,size); width[ColNo]=size; } };) Dr Abudawood

:-O Tanke you very mush Mr .Michael Dunn for your help. And I'll try to do your advice. Dr Abudawood

:confused:How can I calculate the required size of text which can be placed in one column of CListCtrl object and fits in. when I tried to use the next code, some text did not appear all, I get three dots at the end of the appeared text on the column. Can you help me please what is wrong with code ? void CMyDialogDlg::AdjustColSize(int ColNo,CString s) { CClientDC dc(this); CSize sz; CFont *f = m_ListControl.GetFont(); dc.SelectObject(f); sz = dc.GetTextExtent(s,_tcslen(s)); sz.cx += GetSystemMetrics(SM_CXBORDER); if( width[ColNo] < sz.cx ) { m_ListControl.SetColumnWidth(ColNo,sz.cx); width[ColNo]=sz.cx; } } Dr Abudawood
