CListCtrl width of columns question

Hi,
I have a CListCtrl in a dialog which has 4 columns.
When I created the columns I set each column width, but what I realy want is that each column will have the width of the widest item in the column.
I can see that I can get this effect by double-clicking on the separators of the header of the list, But I need to do this from the code (after finishing inserting all the items).

Can someone help ?
Thanks,
Iris.

Have you tried with CListCtrl::SetColumnWidth

CListCtrl::SetColumnWidth
This method changes the width of a column in report view or list view.

BOOL SetColumnWidth(
int nCol,
int cx );
Parameters
nCol
Specifies the index of the column whose width is to be set. In list view, this parameter must be ?1.
cx
Specifies the new width of the column. Can be either LVSCW_AUTOSIZE, LVSCW_AUTOSIZE_USEHEADER or LVM_SETCOLUMNWIDTH.
Return Value
Nonzero if it is successful; otherwise, it is zero.

i think that u need to check the longest string and use
SetColumn or SetColumnWidth to change the width accordingly to the longest string item in this column

something like that:
     LV_ITEM lvItem;
     int nWidth = 0;

     int nColumnCount = 3;
     int nStringWidth, nItemCount = 10;

     for (int j=0; j<nColumnCount ; j++)
     {
          for (int i=0; i<nItemCount; i++)
          {
               lvItem.iItem = i;
               lvItem.iSubItem = j;
               lvItem.mask = LVIF_TEXT;
               m_list.GetItem(&lvItem);
               nStringWidth = m_list.GetStringWidth(lvItem.pszText);
               nWidth = nStringWidth > nWidth ? nStringWidth : nWidth;
          }

          LV_COLUMN lvc;
          lvc.cx = nWidth;
          m_list.SetColumn(j, &lvc);
     }
     m_list.UpdateData();
