that u place in ur module to make tha background clear

[-TM-]

Here you go.

Option Explicit

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 < 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

To use have something like this.

Private Sub Form_Load()

MakeTransparent Me.hwnd, 200

End Sub

Or you can use this code

Const LWA_ALPHA = &H2
Const GWL_EXSTYLE = (-20)
Const WS_EX_LAYERED = &H80000
Public lngresult As Long
Public Const LWA_COLORKEY = 1
Option Explicit
Public Const SWP_NOMOVE = 2
Public Const SWP_NOSIZE = 1
Public Const FLAGS = SWP_NOMOVE Or SWP_NOSIZE
Public Const HWND_TOPMOST = -1
Public Const HWND_NOTOPMOST = -2
Private m_lngRetVal As Long

Public Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hWnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long
Declare Function SetLayeredWindowAttributes Lib "user32" (ByVal hWnd As Long, ByVal crKey As Long, ByVal bAlpha As Byte, ByVal dwFlags As Long) As Long

Public Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hWnd As Long, ByVal nIndex As Long) As Long

Declare Function SetWindowPos Lib "user32" _
(ByVal hWnd As Long, _
ByVal hWndInsertAfter As Long, _
ByVal x As Long, _
ByVal Y As Long, _
ByVal cx As Long, _
ByVal cy As Long, _
ByVal wFlags As Long) As Long



Public Sub maketrans()
lngresult = GetWindowLong(Form1.hWnd, GWL_EXSTYLE)
lngresult = SetWindowLong(Form1.hWnd, GWL_EXSTYLE, lngresult Or WS_EX_LAYERED)
SetLayeredWindowAttributes Form1.hWnd, RGB(255, 255, 255), 128, LWA_COLORKEY 'Change the 255, 255, 255 for the background color that ur 'using (here white), so white will be transparent (ALL things that have white 'background).
End Sub

Public Sub nomaketrans()
SetWindowLong Form1.hWnd, GWL_EXSTYLE, WS_EX_LAYERED
SetLayeredWindowAttributes Form1.hWnd, 255, 255, LWA_ALPHA 'Same Here (U can find LWA_ALPHA on top)
End Sub

And in the form this code
