MSVC++ 6.0, ATL
I'm battling a persistant problem i cannot seem to get around. I have built an ActiveX control using ATL. Using the ATL wizard I have added a connection-point to use events. When using the control in VB I have discovered that if I try to do certain things in VB in the event function I get Access violation exception. Typically this happens when I try to manipulate frames and window properties or trying to display a messagebox. It only happens when I run the built .exe, not when I run it in debug thru VB. As it is nearly impossible to do run-time debugging of VB programs (MSVBVM60.DLL = no debug info) I cannot zero in on the exact reason for the GPF. Is this a known problem? Has any one else experienced it? If you need more info as to my program, just ask. My workaround now is to use i timer-control and flags to do the operations that are not possible from the event-callbacks. This is, for apparent reasons, not an ideal sollution.
