RSClientPrint.Print

I am having an issue with the RSClientPrint control. We have a .net Proxy
class (ASP.NET handler) which is being called by the RSClientPrint.Print
command, bringing the data from Reporting Services and relaying it back to
the control after regex'ing all the urls to point back to our proxy. The
main reason for this is that Reporting Services will not be available from
the client machine as it's hidden behind a firewall.
When executing the Print function, The printer dialog box is displayed,
which when accepted prints the report just as expected, however once the job
has been sent to the printer an `unknown error` is thrown by the Print
Method which is caught by the activex control, which displays an error
message in the screen stating the print failed. Even though the print
succeeds.
The before and after shot are displayed here:
= = = = = =
BEFORE: RSClientPrint.Print("http://{ourwebmachinename}/ReportServer",
"%2fFolder+1%2fFolder+2%2fReport+1&name=administrator", "Report 1")
AFTER:
RSClientPrint.Print("http://{ourwebmachinename}/{ourapp}/ReportServer.ashx",
"%2fFolder+1%2fFolder+2%2fReport+1&name=administrator", "Report 1")
= = = = = =
Removing our proxy and pointing it directly to Reporting Services works
fine, I am wondering why this message is being displayed at all, and the
really frustrating part is that it is a meaningless error.
What I am looking for is an answer to the following:
1. What exactly is the print method doing?
2. At what points could it fail?
3. Has anyone encountered a similar problem, and how have they resolved it?
Thanks for your TimeHello James,
It seems the data returned by your proxy is a little different from that of
reportserver.
You may want to use some tool to catch the HTTP data and compare with the
one from server. Once the preview mode is initiated or the report is
printed, the control instructs the Report Server to print the report using
the EMF rendering extension.
Thanks & Regards,
