Membuat Form transparan di Visual Basic 6.0

Postingan kali ini saya akan berbagi ilmu, bagai mana cara membuat sebuah form terlihat transparan saat dijalankan.

1. Buka aplikasi Visual basic 6.0 dan buka sebuah project baru dan sebuah form
   
   
2. tambah sebuah module dengan cara plilih menu bar Project danpilih Add Module lalu pilih Open.
   
   
3. setelah terbuka module yang kita buat tadi masukan listing dibawah ini kedalam module :
   Declare Function ReleaseCapture Lib "user32" () As Long
   Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
   
   Public Const HTCAPTION = 2
   Public Const WM_NCLBUTTONDOWN = &HA1
   
   
   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 MakeTransparent(ByVal hwnd As Long, Perc As Integer) As Long
   Dim Msg As Long
   On Error Resume Next
   If 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
   
   
4. stelah dimasukan ke module, kembali ke form dan tmbahkan 2 buah timer dan satu buah common button dengan caption "Keluar".
   
   
5. masukan listing dibawah ini di timer1 : Private Sub Timer1_Timer()
   If JmlPersen < jmlpersen =" JmlPersen" jmlpersen =" 230" interval =" 0">
6. kemudian masukan listing ini di timer 2 : Private Sub Timer2_Timer()
   If JmlPersen > 0 Then
   JmlPersen = JmlPersen - 10
   Else
   Unload Me
   Exit Sub
   End If
   MakeTransparent Me.hwnd, JmlPersen
   End Sub
   
   
7. Masukan Listing ini di form load : MakeTransparent Me.hwnd, 0
   JmlPersen = 0
   Me.Timer1.Interval = 50
   
   
8. Dan masukan listing ini di command button1 di event click:
   Me.Timer1.Interval = 0
   Me.Timer2.Interval = 50
   
   
9. dan masukanlisting ini di General-Declaration :
   Dim JmlPersen As Integer
   
   
10. dan jalan kan programnya
