HWND problem with ListControl

[krugger]

Hi; I am building an SDI application which requires a list control found on Tabs of a DialogBar. I managed to initialise the list control to some value. However, users of the tool are required to log-in and the list control is supposed to fill dynamically according to their log. I tried some piece of code to get it done but i got an ENORMOUS assertion error. This is what i get when i move to debug mode: _AFXCMN_INLINE int CListCtrl::InsertColumn(int nCol, const LVCOLUMN* pColumn) { ASSERT(::IsWindow(m_hWnd)); return (int) ::SendMessage(m_hWnd, LVM_INSERTCOLUMN, nCol, (LPARAM)pColumn); } Can someone please help me to understand what this means and possibly how to overcome it. I badly need this. Thank you; Krugger

It simplely means that the listcontrol was not created.. are you trying to insert something out of the scopeof the listcontrol variable or out of the dialog ???
