Membuat Form Transparan

Tips kali ini adalah bagaimana Membuat Form Transparant dengan Visual Basic, disini kita menggunakan Fungsi API yaitu GetWindowLong, SetWindowLong dan SetLayeredWindowAttributes. Saya rasa tidak perlu penjelasan yang detail untuk hal ini sobat bisa langsung melihat penampakannya dibawah ini
Bagaimana dengan Codingnya ikuti Langkah - Langkah Berikut :


  • Buat Project Baru Standart Exe
Ketik Coding dibawah ini pada Form Project Sobat


Option Explicit


Private Const WS_EX_LAYERED = &H80000
Private Const GWL_EXSTYLE = (-20)
Private Const LWA_COLORKEY = &H1
Private Const LWA_ALPHA = &H2


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 crColor As Long, ByVal nAlpha As Byte, ByVal dwFlags As Long) As Long


Private Sub Form_Load()
Call SetWindowLong(Me.hwnd, GWL_EXSTYLE, GetWindowLong(Me.hwnd, GWL_EXSTYLE) Or WS_EX_LAYERED)
Call SetLayeredWindowAttributes(Me.hwnd, RGB(255, 0, 255), 128, LWA_ALPHA Or LWA_COLORKEY)
End Sub


Untuk ketajaman transparant sobat bisa menggati Angka - Angka yang berwarna merah dengan angka yang lain (maximal value 255).




Atau Ada Cara Kedua

Sisipkan Kode Ini Di Module




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 Declare Function UpdateLayeredWindow Lib "user32" (ByVal hWnd As Long, ByVal hdcDst As Long, pptDst As Any, psize As Any, ByVal hdcSrc As Long, pptSrc As Any, crKey As Long, ByVal pblend As Long, ByVal dwFlags As Long) As Long
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 Const GWL_EXSTYLE = (-20)
Private Const LWA_COLORKEY = &H1
Private Const LWA_ALPHA = &H2
Private Const ULW_COLORKEY = &H1
Private Const ULW_ALPHA = &H2
Private Const ULW_OPAQUE = &H4
Private Const WS_EX_LAYERED = &H80000

Public Function isTransparent(ByVal hWnd As Long) As Boolean
On Error Resume Next
Dim Msg As Long
Msg = GetWindowLong(hWnd, GWL_EXSTYLE)
If (Msg And WS_EX_LAYERED) = WS_EX_LAYERED Then
isTransparent = True
Else
isTransparent = False
End If
If Err Then
isTransparent = False
End If
End Function

Public Function MakeTransparent(ByVal hWnd As Long, Perc As Integer) As Long
Dim Msg As Long
On Error Resume Next
If Perc < 0 Or Perc > 255 Then
MakeTransparent = 1
Else
Msg = GetWindowLong(hWnd, GWL_EXSTYLE)
Msg = Msg Or WS_EX_LAYERED
SetWindowLong hWnd, GWL_EXSTYLE, Msg
SetLayeredWindowAttributes hWnd, 0, Perc, LWA_ALPHA
MakeTransparent = 0
End If
If Err Then
MakeTransparent = 2
End If
End Function

Public Function MakeOpaque(ByVal hWnd As Long) As Long
Dim Msg As Long
On Error Resume Next
Msg = GetWindowLong(hWnd, GWL_EXSTYLE)
Msg = Msg And Not WS_EX_LAYERED
SetWindowLong hWnd, GWL_EXSTYLE, Msg
SetLayeredWindowAttributes hWnd, 0, 0, LWA_ALPHA
MakeOpaque = 0
If Err Then
MakeOpaque = 2
End If
End Function
"

LAlu Di Form

Private Sub Form_Load()
MakeTransparent Me.hWnd, 200
'ubah nilainya untuk mengatur tingkat
'ke-transparan-annya. range (0-255)
'0 form akan menghilang total
'255 form akan normal / terlihat jelas
End Sub
