Windows permission problem

rbuser

Hi there,

I have a Delphi COM object which generates ReportBuilder report as PDF file.
The COM object gets created and called from a ASP page.

I am getting a error: Cannot generate report. Canvas does not allow drawing.
I assigned the anonymous web user IUSR_COMPUTERNAME as
a member of administrator of the local machine, then the report works.

This gives me an impression that it is a permission issue, but the problem
only
occurs to certain report, not all reports.

The question is does RB generate any temp file during report creation? e.g.
to Windows
temp folder which requires write permission?

Thanks a lot for any help!

Regards,
Ian

Hi Ian,

Which version of ReportBuilder are you using?

The exception 'Canvas does not allow drawing' occurs when RB cannont access
the printer. Typically this is thrown when there is not a default printer
installed. However, if you are running as a service, this may mean that the
service might not have the same security rights as the current user. This
would also cause a problem.

In order to deal with these issues, we enhanced RB 6.0+ so you can set the
printer name to 'Screen' and then ReportBuilder does not need access to an
actual print driver. My advice is to consider upgrading to our latest
version of ReportBuilder, version 9.01.

I am using RB version 6.03 Enterprise

The solution without upgrading to new version:

Install a printer on the server.
So RB could get a printer handle while creating PDF file.
