Well it has been 10 years and in an attempt to use the SkinFramework again I have found that this performance problem still exists!  How can I prevent the ListBox control from drawing the scrollbar after each item is added to it?  I have the control's Visible property set to False, and the Form's AutoRedraw property set to False.

Have you tried turning off the autoredraw for the form?

me.AutoRedraw = False
'load listbox
me.AutoRedraw = True

Haven't had a chance to try it, but I think it'll work.

I was referring to a standard VB6 listbox control, so your code sample won't work.
 
Neither hiding the Listbox control, nor calling LockWindowUpdate on it improves the poor performance.
 
However, I did find a workaround that appears to solve the problem:
        SkinFramework1.RemoveWindow Listbox1.hWnd
        ' fill listbox code goes here
        SkinFramework1.ApplyWindow Listbox1.hWnd
Do you see any potential problem or side effect with this approach?

Hi,
 
Guess ListBox redraw Scrollbar on each change.
 
Just add
 m_wndListBox.SetRedraw(FALSE);
 m_wndListBox.SetRedraw(TRUE);
 
around populating and you will get same 1sec.

I have a listbox that gets populated with 10,000+ items.  This typically takes only 1 second, but if the application is skinned it takes 8 seconds!  Why should skinning the app effect the performance of seemingly unrelated tasks?
