I am using the crystal reports viewer control, and the eventhandler() function to try and handle some of the crystal events.

The eventhandler() function is returning .t. , but my custom code for the events doesn't seem to fire.

I have included the code below, I am paticularly unsure about the newobject/addobject lines, as the eventhandler() function does not accept my object variables, unless I include the newobject lines.


the code defining the class is as follows

do form menu.scx
read events

DEFINE CLASS myclass AS session

and the code for the form is as follows



*!* If the CRViewer is added to the form, with out any report to preview
*!* Visual FoxPro will give an error stating that the "OLECONTROL may be corrupt"
*!* This has to do with the drawing method of certain types of controls being designed
*!* more specifically for Visual Basic. To get around this add the Smart Viewer
*!* to the form when you want to view the report and preview right away. If the
*!* preview method is not called you will get an error.
