Always have problem on resize the common controls with full drag. Too many refreshes cause screen flashing during sizing. Seems like it has something to do with the Class style.
Any idea on how to make resizing smoother.

Yes this is caused by that fact many controls have CS_VREDRAW and CS_HREDRAW style. I also had the same problem with Extended combo box. I placed it on rebar control and when I resize it it flashes. It is not simple to change it but you can still try. You should get WNDCLASSEX structure of specific control class with GetClassInfoEx. Do not forget to fill cbsize of this structure prior to using it. Then change style and class name. Register you class. Then when creating control use you class which has the same attributes but another style.

I guess we are out of luck when dealing with common controls in the dialog box resouce. Unless we create them on the fly.
