Crystal Reports "Load Failed" from web form Grrrrr

Hi there. I'm a bit of a newbie, and I would appreciate any help that
anyone can give me on an error I'm getting with Crystal Reports.

Every time I attempt to view a report using the Crystal Report Viewer,
I get a "Load Report Failed" error, and I'm not sure what I can do to
resolve it.

I know it's not the connection to the data -- I'm able to get a
datagrid to display the data just fine after filling a dataset. I
tried searching the Crystal Decisions support site, and all of their
"load failed" info has to do with DLLs not being in the right place,
or permissions on the actual .RPT file, but all of that seems to be
in order.

These are the lines of code that keep kicking on me.


crReportDocument.Database.Tables(0).SetDataSource(DS)
CrystalReportViewer1.ReportSource =
crReportDocument

DS and crReportDocument are Dim-ed earlier like this:

[i:8f42c70c71] Dim crReportDocument As New CrystalReport1
Dim DS As DataSet[/i:8f42c70c71]

Any help would be greatly appreciated.

Thanks,

Jeff
 
This is the message I found on other forum:

Hello.

I think I have the same problem, and am pretty sure I have it narrowed
down. While the CrystalReportViewer object has the correct login
information set, the ReportDocument object does not have the password
set. For some reason it never gets set even if I explicitly set it.

I'm ready to call Crystal Decisions on this one...

Looks like it's not only you having this problem.

Thanks for the quick reply. Actually I'm not having logon issues. Mine
seems to be failing to load the report document itself. As I said,
logon to the database seems to work, since I can absolutely get the
very same dataset to populate a datagrid.

Here's the code on the page, in case anyone can see where I'm going
wrong. (I've XXXXX'd out the server and initial catalog names in the
connection string.)
