Semi Transparent Form using VB6

Question

Is it possible to create a form that is semi transparent, It should be visible over any open windows, not hidden behind ? Please guide!

Answer 1

Sure, see Karl Peterson's "Translucent" example: http://vb.mvps.org/samples/Translucent/

To keep the form visible over other windows, you want to use the SetWindowPos API function.

Private 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

Private Const HWND_TOPMOST = -1
Private Const SWP_NOMOVE = &H2
Private Const SWP_NOSIZE = &H1
Private Const OnTopFlags = SWP_NOMOVE Or SWP_NOSIZE

Public Sub FormOnTop(frm As Form)
    Call SetWindowPos(frm.hWnd, HWND_TOPMOST, 0&, 0&, 0&, 0&, OnTopFlags)
End Sub
