Remarks

CComControl is a set of useful control helper functions and essential data members for ATL controls. When you create a standard control or a DHTML control using the ATL Control Wizard, the wizard will automatically derive your class from CComControl. CComControl derives most of its methods from CComControlBase.

For more information about creating a control, see the ATL Tutorial. For more information about the ATL Project Wizard, see the article Creating an ATL Project.

For a demonstration of CComControl methods and data members, see the CIRC sample.
