Opaque Form

[SeanK]

Does any know how to make a form Opaque or translucent (NOT transparent)?

[Hack]

Const LWA_COLORKEY = &H1
Const LWA_ALPHA = &H2
Const GWL_EXSTYLE = (-20)
Const WS_EX_LAYERED = &H80000
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 crKey As Long, ByVal bAlpha As Byte, ByVal dwFlags As Long) As Long
Private Sub Form_Load()
    'KPD-Team 2000
    'URL: [url]http://www.allapi.net/[/url]
    'E-Mail: [email][email protected][/email]
    Dim Ret As Long
    'Set the window style to 'Layered'
    Ret = GetWindowLong(Me.hWnd, GWL_EXSTYLE)
    Ret = Ret Or WS_EX_LAYERED
    SetWindowLong Me.hWnd, GWL_EXSTYLE, Ret
    'Set the opacity of the layered window to 128
    SetLayeredWindowAttributes Me.hWnd, 0, 128, LWA_ALPHA
End Sub

How on earth do you find somehting like this out. The only way must be to spend hours reading an api manual.

This is excellent and something I have been looking for for ages.
thanks Hack.

Is it possible to make just the form transparent or semi transparent without affecting the controls on it?

I'mnot perfectly sure bout this but shouldn't you be able to pass the hWnd of the controls in the place of Me.hWnd and set it to the value for normal forms? I can't remember if all controls have a hWnd cos i'm not at my PC with VB on so I can't check but I think they do.

So I couldn't be of anymore help.
