Well this is odd...
I have a Microsoft Report in my application which usually works... however on the odd occasion (when we need it most!) it throws the rather spurious error 'The source of the report definition has not been specified'.
The application itself generates hundreds of single (1 or 2 pages per account) reports, saves them to disc and emails them OK.
We then try to bulk print the rest of the reports for accounts that have no email address. This generates the above error!
Printing a single account or a small range of accounts works OK.
Also, this does not happen on every machine. We even completely wiped one machine and reinstalled windows but it still fails.
Anyone got any ideas?
Thanks in advance.
