1) The g_PaintManager->PaintDocumentClientAreaBkgnd() method doesn’t support scrolling.
2) It is not completely clear what the problem is. Which icon is not displayed? Would you send us some screenshot(s) or a test project?

HI, I solved the problem about icon in CTreeCtrl, was my problem.
The problem of the mouse persist and I not understand why. I’m using VC8 - ProfUIS 2.5.4. I have a CTreeCtrl*** inside of CExtControlBar.
If I start my exe inside of VC, the mouse is display correctly (when is over CTreeCtrl), indipendently if I compile in Debug or in Release. If I start the program outside af VC (double click on exe icon), the mouse in not displayed when is over CTreeCtrl. Have you experience of similar error in ProfUIS?
Unfortunately I cannot send you my proyect because is very big and it has integration with database and other object.
***
I have created CTreeCtrl as a child window of CWnd derived class, this class is created as child of CExtControlBar.
I appreciate any help.
Tx a lot

No, we have never encountered the similar problems before and no our customers reported about these problems. We have several samples in Prof-UIS and they are working correctly. Would you try to create a small project and reproduce the problem?

I seen g_PaintManager->PaintDocumentClientAreaBkgnd() method doesn’t support scrolling. There is a method I can use to implement it?

All the background painting methods in all paint managers were designed for painting non-scrollable content. So, you should do the following:
1) Redraw your view window when you receive the WM_HSCROLL and WM_VSCROLL messages.
2) Handle the WM_PAINT message and invoke the paint manager for painting the background like you need.
3) In the the WM_PAINT message handler, invoke the dc.SetViewPortOrg( 0, 0 ) code before calling the paint manager’s API.
