I’m using Prof-UIS 2.64.
I’ve downloaded SkinScrollWnd sample for skinning common MFC controls. And everything works fine except one thing: when I click multiple times (fast) on scrollbar’s arrows it’s lagging – the scrollbar’s gripper is not moving. For single scrollbars this problem exists too.

What can I do?

Thank you for your previous assistance.

I have a CView derived class that uses CExtScrollBar derived scroll bars. I want to embed the view class in a CExtTabPageContainerWnd. When I do this, the view class displays correctly but the scroll bars do not appear.

The same happens when I use CScrollBar derived scroll bars.

When I instantiate the view in a stand-alone window everything displays ok, including the scroll bars.

Is there a messaging sink / redirection or other form of declaration associated with the CExtTabPageContainerWnd that I have omitted?

Here is the simplest possible test project with the tab page container:

Could you please insert your view creation code into it and then send us modified version of this project?

I’m not sure, but this problem related to all scrollbars in 2.64. All examples with scrollbars having this behavior.

We published different versions of SkinScrollWnd-based samples many times in both Prof-UIS forums. Please tell us the exact URL of the sample you have downloaded so we check the problem.
