A TrackBar control does not repaint itself until it gets the focus. So, if you enable run time changes of appearance, and you have one, you'll have to set and reset the focus in order to show it properly.

As I have already developed and using DLL(MFC/NON MFC) created in VC 6.0.
So Is there any advantages if I covert this into ATL COM

And if I m capable of doing so..i.e. Converting DLL(MFC/NON MFC) into ATL COM application
then Whats type of care must have to be taken Like ...........
1> Global and local variable .or
2> Public/protected members of CLASS .or
3> Exported functions of DLL
