VB skin++ MDI窗口禁止最大化、最小化按钮
如题，我用了skin++，但是MDI窗口没法用API禁止最大化、最小化按钮了，求教 --------------------编程问答-------------------- 你是怎么禁止的?贴一下失败的代码 --------------------编程问答-------------------- 最好不显示最大化、最小化按钮 --------------------编程问答-------------------- 失败的API代码：-------------------------------------------------------------------------------------
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
Const WS_MINIMIZEBOX = &H20000
Const WS_MAXIMIZEBOX = &H10000
Const GWL_STYLE = (-16)
Private Sub MDIForm_Load()
Dim L As Long
L = GetWindowLong(Me.hwnd, GWL_STYLE)
L = L And Not (WS_MINIMIZEBOX)
L = L And Not (WS_MAXIMIZEBOX)
L = SetWindowLong(Me.hwnd, GWL_STYLE, L)
End Sub

'以下去掉系统菜单中的最大化，最小化和还原

DrawMenuBar Me.hwnd
Call RemoveMenu(hMenu, nCount - 7, MF_DISABLED Or MF_BYPOSITION)

End Sub
--------------------编程问答-------------------- 直接
-------------------------------------------------------------------------------------
Private Sub MDIForm_Resize()
On Error Resume Next
Me.WindowState = 0
Me.Height = H
Me.Width = W
End Sub

补充：VB , API
