Menjadikan Form Semi Transparan

Bagaimana cara membuat form semi transparan menggunakan Visual Basic 6.0. Simaklah kodenya di bawah ini:
Option Explicit 

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 color As Long, ByVal x As Byte, ByVal alpha As Long) As Boolean

Const
LWA_BOTH = 3
Const LWA_ALPHA = 2
Const LWA_COLORKEY = 1
Const GWL_EXSTYLE = -20
Const WS_EX_LAYERED = &H80000

Dim
iTransparant As Integer

Sub
MakeTransparan(hWndBro As Long, iTransp As Integer)
On Error Resume Next

Dim
ret As Long
ret = GetWindowLong(hWndBro, GWL_EXSTYLE)

SetWindowLong hWndBro, GWL_EXSTYLE, ret Or WS_EX_LAYERED
SetLayeredWindowAttributes hWndBro, RGB(255, 255, 0), iTransp, LWA_ALPHA
Exit Sub

End Sub

Contoh penggunaan membuat form semi transparan
Option Explicit 

Private Sub
Form_Load()
On Error Resume Next
MakeTransparan Me.hWnd, 75
End Sub
