Transparent background

How do I make a picture to have a transparent background ??

You could use an Imagebox or have the Picture's border style to None.

Or this code which will make any control (with a hwnd) transparent:

Code:

---

Private Const WS_EX_TRANSPARENT = &H20&
Private Const GWL_EXSTYLE = (-20)

Private Declare Function SetWindowLong Lib "user32" _
  Alias "SetWindowLongA" (ByVal hwnd As Long, _
  ByVal nIndex As Long, ByVal dwNewLong As Long) As Long


Public Function MakePictureTransparent(PicCtl As Object) As Boolean

On Error Resume Next
PicCtl.BackColor = PicCtl.Parent.BackColor
SetWindowLong PicCtl.hwnd, GWL_EXSTYLE, WS_EX_TRANSPARENT
MakePictureTransparent = Err.LastDllError = 0

End Function


Usage

MakePictureTransparent Picture1
