Method or data member not found error for listsubitems in VB6

I am getting the error "Method or Data Member not found" for ListSubItems whenever I try to compile the project. I have added the SP6 component, MSCOMCTL.OCX. But still I am getting this error. In the drop down ListSubItems is not available.

Public Function SetBoldToListItemInListView(lv As ListView, lvwItem As ListItem, bBold As Boolean) As Boolean
    Dim i As Integer
    On Error GoTo EH

    ResetBoldInListView Not bBold, lv  
    lvwItem.EnsureVisible

    For i = 1 To lvwItem.ListSubItems.Count
        lvwItem.ListSubItems(i).Bold = True
    Next  

    lvwItem.Bold = True 
    lvwItem.Selected = True 
    lv.Refresh  
    SetBoldToListItemInListView = True

ExitProc:
    On Error Resume Next  
    Exit Function

EH:    
    Error_Handler "Support / CheckUncheckItemsInListView"
    Resume ExitProc
End Function
