شفافیت(Transparency)

چگونه من می توانم شفافیت یک صفحه در ویژوال بیسیک را تغییر دهیم؟:20:

Private Const GWL_EXSTYLE = (-20)
Private Const WS_EX_LAYERED = &H80000
Private Const LWA_ALPHA = &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 SetLayeredWindowAttributes Lib _
"user32" (ByVal hWnd As Long, ByVal crKey As Long, _
ByVal bAlpha As Byte, ByVal dwFlags As Long) As Long
Private Function TranslucentForm(frm As Form, TranslucenceLevel As Byte) As Boolean
SetWindowLong frm.hWnd, GWL_EXSTYLE, WS_EX_LAYERED
SetLayeredWindowAttributes frm.hWnd, 0, TranslucenceLevel, LWA_ALPHA
TranslucentForm = Err.LastDllError = 0
End Function
Private Sub Form_Load()
TranslucentForm Me, 100
End Sub

ممنون از کمک شما
