I am working on a CDHTMLDialog based application where I ahve added a CListCtrl as shown below. The list control has only one column. IDD_TEST_DIALOG DIALOGEX 0, 0, 419, 286 STYLE DS_SETFONT | DS_FIXEDSYS | DS_CENTER | WS_MINIMIZEBOX | WS_POPUP | WS_VISIBLE | WS_CAPTION | WS_SYSMENU | WS_THICKFRAME EXSTYLE WS_EX_APPWINDOW FONT 8, "MS Shell Dlg", 0, 0, 0x1 BEGIN CONTROL "",IDC_LIST_TEXT,"SysListView32",LVS_REPORT | LVS_OWNERDATA | LVS_NOSORTHEADER | NOT WS_VISIBLE | WS_BORDER | WS_TABSTOP,20,143,397,136 END The problem is that I can drag the colum header to extreme left and the column goes hidden. To bring it back I will have to again drag the column header to the right. I want to prevent resizing of this column so that the user cannot drag this completely to the left and make it hidden. I did try the following code but it is not working. void CMyTestDlg::OnHDNEndtrackListLog(NMHDR *pNMHDR, LRESULT *pResult) { LPNMHEADER phdr = reinterpret_cast<LPNMHEADER>(pNMHDR); // TODO: Add your control notification handler code here if(m_ListCtrl.GetColumnWidth(0) < 100) { m_ListCtrl.SetColumnWidth(0, 500); } *pResult = 0; } Since I have very less time to implement this, I request you kindly give me some examples from MFC Dialog based applications.
