"User Cancelled" Error while viewing Crystal report

Hi,
I have a Crystal Reports v10 Report that has been working fine
for the past X years. It is invoked by a VB6 app using the
Report Viewer. For some reason, sometimes when the report is
executed, it displays the message "User Cancelled" immediately
after the viewer window is opened, even though the user did not
cancel the report. None of the code has changed, neither has the
report.

Does anyone have any clue as to why this message should appear?

Very urgent, Thanks in Advance...

Regards,
AnandhSometimes I see this message when there is an issue with the print spooler on the computer where the report is being generated. Try going to Control Panel > Administrative Tools > Services and then restarting the Print Spooler service. After doing this, reboot the computer.

If this doesn't work, then it isn't the print spooler causing the problem.

Good Luck! :)

" the object invoked has disconnected from its clients"

I′m configuing a transacional replicationand after concluding it does not function, it is in the status initiating and later it gives the message: " the object invoked has disconnected from its clients"
Can you help me?
I have never heard of this error wrt replication.
The following article indicates it is a windows issue and the resolutions hopefully will help: http://www.kbalertz.com/Feedback_293631.aspx
Another poster upgraded his MDAC version to 2.8 and claims this solved his issue, although upgrading MDAC would not seem to be connected to the above article. Anyway, please let us know if you go down either route and how it works out.
