ListView Control

Flat Column Headers

To make the column headers flat, all you need to do is add the code below to a module, and call SetFlatHeaders with the hWnd of the ListView control.

Private Const GWL_STYLE = (-16)
Private Const LVM_FIRST = &H1000 '// ListView messages
Private Const LVM_GETHEADER = (LVM_FIRST + 31)
Private Const HDS_BUTTONS = &H2
Private Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long
Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As Long
Private Declare Function SendMessageLong Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Long) As Long

Public Sub SetFlatHeaders(lTreeViewhWnd As Long)
Dim lS As Long
Dim lhWnd As Long

   ' Set the Buttons mode of the ListView's header control:
   lhWnd = SendMessageLong(lTreeViewhWnd, LVM_GETHEADER, 0, 0)
   If (lhWnd <> 0) Then
      lS = GetWindowLong(lhWnd, GWL_STYLE)
      '// change this to lS = lS Or HDS_BUTTONS to make them normal again
      lS = lS And Not HDS_BUTTONS
      SetWindowLong lhWnd, GWL_STYLE, lS
   End If
  
End Sub
