1)  I want to programmatically enable editing of current SELECTED/FOCUSED list item (in CListCntrl). How to do it (with input focus)?

2)  How to enable editing of a specific column within a row (in multi-column list control)?
-----

For example in AppWizrd when you create a list control (in a dialog) you can set a property flag ("Edit lable" check box) in property page.

I want to do it at run time programmatically. I tried the following, but is not working:

Failed method 1:
-------------------------
//begin in-place editing of the newly inserted row
CEdit * pEdit = m_ListCtrl.EditLabel( m_ListCtrl.GetItemCount( )  );
if (NULL != pEdit )
pEdit->SetFocus();

Failed method   2:
------------------------------
//Insert items
LV_ITEM lvi;
lvi.mask = LVIF_TEXT | LVIF_STATE;
lvi.iItem = m_ListCtrl.GetItemCount( );
lvi.iSubItem = 0;
lvi.iImage = 0;
lvi.stateMask =  LVIS_CUT | LVIS_DROPHILITED | LVIS_FOCUSED | LVIS_SELECTED |  LVS_EDITLABELS | LVS_SHOWSELALWAYS ;
lvi.state = LVIS_FOCUSED | LVIS_SELECTED ;
       
lvi.pszText = "";
//insert this item now!            m_ListCtrl.InsertItem(&lvi);
//make this new item selected/in-focus
m_ListCtrl.SetItemState(m_ListCtrl.GetItemCount( ), LVIS_FOCUSED | LVIS_SELECTED, LVIS_SELECTED);
            UpdateData(FALSE);

//send begin lable edit message
m_ListCtrl.PostMessage(WM_NOTIFY, IDC_LISTCTRL, (LPARAM)&msgHdr);
//or this line!!!!!!!!!!!!!!!! (alternatively)            ::SendMessage(m_ListEmailUserNames.GetSafeHwnd(), LVN_BEGINLABELEDIT, IDC_LISTCTRL,  (LPARAM)&lvi);

GetItemCount will always be one greater than the highest available item-index for the list ctrl !

Using that for item-index, hence, will never address any valid index !

I could edit my item by issuing EditLabel(correct index). In fact, try subclassing the edit control in OnBeginLabelEdit and the editing feature looks slick !
