How to update AutoCAD-View?

[Anonymous]

My Problem:
I draw a entity for example a polyline. I change the color of the line. Then I open a CDialog with DoModal().
The PROBLEM: The color of line is not changed! After closing the dialog the color is changed.
I think its a problem with actualize the autocad view.
This function does not work:

CView* pActiveView = acedGetAcadFrame()->GetActiveFrame()->GetActiveView();
pActiveView->UpdateData(FALSE);
pActiveView->UpdateWindow();

Could somebody help me? How can I update the view before opening the Dialog?

Thanks for help!
