Public Const LVM_FIRST = &H1000 
Public Const LVM_SETCOLUMNWIDTH = (LVM_FIRST + 30)

Public Const LVSCW_AUTOSIZE_USERHEADER = -2 
Public Const LVM_GETHEADER = (LVM_FIRST + 31) 

Declare Function SendMessage Lib "user32.dll" Alias _

ByVal lParam As Long) As Long 


Public Sub ResizeHeader(boolFirstColVisible As Boolean, lstv As ListView)

For lColumn = lCounter To lstv.ColumnHeaders.Count - 1 
SendMessage lstv.hWnd, _
