I am writing an application with Measurement Studio and Visual C++ that will allow the user to create graphs on the fly. I need to give them the capability to select a graph and resize it in a manner consistent with most other Windows programs (i.e. resize handles). I have tried various implementations of the CRectTracker class and can get it to work for Microsoft controls, but I can not get it to work with the CNiGraph (the only one I have tried so far). The code runs but I never get the selection box or handles around the control. Is there a way to do this and is there an example anywhere that I can go from? Any help would be appreciated.
