Report Control - An Outlook 2000-Style SuperGrid Control



Click here for larger image

Environment: VC6, Windows 98, NT4 (IE4), Windows 2000.

This ReportCtrl control is an Outlook 98/2000 style SuperGrid control. I've seen many implementations, most of them based on the standard CListCtrl. All implementations have their specific weaknesses. This implementation tries to overcome some of the weaknesses, although for some purposes it may introduce others.

The documentation is sparse, because I do not have much time to write documentation. However, the included demo is a great help in understanding how to use the features of the control and many features are demonstrated in a practical manner. The interfaces of the controls highly resemble the interfaces of similiar MFC controls, like the list control and header control. So, for the more experienced MFC coder, it should not be a big problem to understand how to use the control in their own projects...
