Hi,
I'm using visual studio 2010 with crystal reports (Support Pack 12 (v.13.0.12.1494).
Most of my crystal reports use data from an access database, for an unknown reason I cannot print or export my reports because I'm always presented with the following error "crystal report print Attempted to read or write protected memory. This is often an indication that other memory is corrupt." The application then crashes!
I have a MainForm(startup form) -> projectListForm -> reportForm(crystal report)
In my mainForm's Load event, I'm connecting to the access database that the crystal report also connects too, if I remove this connection in the MainForm then I can actually Export and Print from crystal report when I open the report form;
Also if I set my startup form to the reportForm, the Export and Print work without a problem.
I would greatly appreciate any help I can get!
Thank you,
The exception detail is :
System.AccessViolationException was unhandled
Message=Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
