将VB5中的ToolBar变成平面的   
　           
'make a new project
'with a toolbar on it (name = toolbar1)
'insert the next code
'press F5

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal HWnd As Long, ByVal wMsg As Long, ByVal wParam As Integer, ByVal lParam As Long) As Long
Private Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" (ByVal hWnd1 As Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, ByVal lpsz2 As String) As Long
Const WM_USER = &H400
Const TB_SETSTYLE = WM_USER + 56
Const TB_GETSTYLE = WM_USER + 57
Const TBSTYLE_FLAT = &H800

Private Sub SetToolBarFlat(tlbTemp As Toolbar)
Dim lngStyle As Long
Dim lngResult As Long
Dim lngHWND As Long

lngHWND = FindWindowEx(tlbTemp.HWnd, 0&, "ToolbarWindow32", vbNullString)
lngStyle = SendMessage(lngHWND, TB_GETSTYLE, &O0, &O0)
lngStyle = lngStyle Or TBSTYLE_FLAT
lngResult = SendMessage(lngHWND, TB_SETSTYLE, 0, lngStyle)
tlbTemp.Refresh

End Sub

Private Sub Form_Load
Call SetToolbarFlat(Toolbar1)

End Sub
(在VB6以上版本中ToolBar已经可以设置成平面的了，所以上面的范例不再起作用)
