如何让鼠标在VB窗体上点击时无效,即操作焦点作用在操作系统上!

如题所述

Const LWA_COLORKEY = &H1
Const LWA_ALPHA = &H2
Const GWL_EXSTYLE = (-20)
Const WS_EX_LAYERED = &H80000
Const WS_EX_TRANSPARENT As Long = &H20&
Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As Long
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 SetLayeredWindowAttributes Lib "user32" (ByVal hwnd As Long, ByVal crKey As Long, ByVal bAlpha As Byte, ByVal dwFlags As Long) As Long
Private Sub Form_Load()

Dim Ret As Long
Ret = GetWindowLong(Me.hwnd, GWL_EXSTYLE)
Ret = Ret Or WS_EX_LAYERED Or WS_EX_TRANSPARENT
SetWindowLong Me.hwnd, GWL_EXSTYLE, Ret
SetLayeredWindowAttributes Me.hwnd, 0, 255, LWA_ALPHA

End Sub

是这个吗
