What is the proper way to end a program where an error is detected with system data in the Init or InitDialog methods? I define some fonts in the InitDialog method and then delete them in the Cancel method. If on the detected error condition, I invoke the cancel method after presenting an error message, I get an invalid argument on the DeleteFont() request. Also, if I have a method defined to get control from a ConnectPosChanged() request, that also gives me an error on the dialog requests dealing with changed Edit control elements. These items do not give an error if I do not attempt to call the Cancel method before the Init or InitDialog methods have returned.
