At this time I using the MS VC++.NET 2003. But VC++ 6.0 i will get Wrapper Class of MSCOMM but i will not get in VC++.NET.

1. Create a MFC application having care of enabling the ActiveX controls check of the Advanced features tab of the MFC Application Wizard window.
2. Select Project->Add Class item of Visual Studio Main menu.
3. Choose the MFC node on the treview in the newly appeared window.
4. Select MFC Class From ActiveX Control.
5. Click button Add.
6. Choose Microsoft Communication Control... in the newly appeared list.
7. Click button Add.

for (int row = 0, endRow = the_list.GetItemCount(); row < endRow; row++) //Iterate thorough the rows
{
  for (int col = 0; col < column_count; col++) //Iterate the "columns of this row"
  {
    CString Text;
    Text = the_list.GetItemText(row, col);
    if (Text.CompareNoCase(the_text_to_search_for) == 0)
    { //This "cell" contains the text we are searching for, let's select this row for example
      the_list.SetItemState(row, LVIS_SELECTED, LVIS_SELECTED);
      break; //break from the column iteration since we already found the string, no need to look for more
    }

Its nice,only one problem is there how can i use it for full application i mean for all ListCtrl those are used in Application.
