I am getting the following error with crystal reports within VS2010 C#:
System.Runtime.InteropServices.COMException (0x80004005): Invalid export type.
from this code which fails on the second line:
reportDocument.ExportOptions.ExportDestinationType = ExportDestinationType.DiskFile;
reportDocument.Export();
The full error is:
System.Runtime.InteropServices.COMException (0x80004005): Invalid export type.
