    Posted: 27 October 2008 at 5:08am
Transparency doesn't work with transparent usercontrols(ocx)?



All controls and the usercontrol are set to transparent.
The usercontrol itself is transparent, but not the controls on it, as you can see on the second screenshot.
Is there a way to solve this problem?

You can try to use a tabworkspace as background for the usercontrol, adding a single line in the resize event like:
tabworkspace.move 0 ,0 , usercontrol.scalewidth,usercontrol.scaleheight

i think that will work

Thank you.
Your solution only works correct, if the UserControl fills the whole TabPage.
But if the UserControl is only a part of the TabPage, then you will notice a problem with the gradient of the color.

Hmm, yes you are right.

If you are willing to do some ugly stuff here's a horrific 'workaround'

In your UC place this code 

Sub Init(X As Single, Y As Single, Width As Single, Height As Single)

    TabControlPage1.Move 0 - X, 0 - Y, Width, Height

    Dim myControl As Control



    For Each myControl In UserControl.Controls



        If Not TypeOf myControl Is XtremeSuiteControls.TabControlPage Then

            On Error Resume Next

            myControl.Left = myControl.Left + X

            myControl.Top = myControl.Top + Y

            On Error GoTo 0

        End If



    Next



End Sub

Then in your calling form something like 

Private Sub Form_Load()

    myControl.Init myControl.Left, myControl.Top, TabControlPage1.Width, TabControlPage1.Height

End Sub


But only if you really must.
Any other workaround or real solution will be better
