I am making a SDI application in that i have used splitter control in that splitter contol i have made a  list control using this code
CListCtrl& lc = GetListCtrl();
lc.ModifyStyle(0,LVS_REPORT);
lc.InsertColumn(0, _T("Name"), LVCFMT_LEFT,50);
LVCOLUMN col;
col.mask = LVCF_FMT | LVCF_TEXT;
col.pszText = _T("Monitor Type");
col.fmt = LVCFMT_LEFT;
lc.InsertColumn(1, &col);
lc.SetColumnWidth(1,150);
lc.InsertColumn(2, _T("Host(Url)"), LVCFMT_LEFT,150);

In my application when i click a toolbar button a dialog box opens up and the user has to fill the value in that dialog boxes columns and when the user will press the save button then those values will be saved in previous list control

Now the prolem is i am calling object of that list ctrl class in my dialog boxes class its giving an error degub assertion failed when i run the program
and when i use dialog variables in list ctrl class it does not add up the values to list ctrl
how to do it

and have you traced at which like exactly you are getting assertion failure by debugging or may be by putting messageboxes in between. ?

I suspect your dialog window and listcontrol is not FULLY created when you are trying to add items to your control..

you may check with IsWindow function if window/control is fully ceated..

like this :

if(IsWindow(obj->lc.m_hWnd))
   obj->lc.InserItem(0,strName);

Otherwise try adding item on some button click and check if you are getting assertion or not...
