Hi there,

I try to generate a simple report with Crystal Reports for .NET.
I've already done some reports from xml files or from databases, but my problem is now to use an ADO.NET DataSet as a data source.

I have my .xsd file to describe the structure and I fill the dataset this way :
-        Dim DSLicences As New Odyssee.AcroDroits.DataSetLicences
-        DSLicences.LicenceWeb.AddLicenceWebRow(11, 13, #12/13/2004#, 11, 13)

Then I set the datasource in the report :
-        Dim MyReport As New LicencesReport
-        MyReport.SetDataSource(DSLicences)

And finally give it to the viewer that is on my Form :
-        CRViewer.ReportSource = MyReport
-        CRViewer.Refresh()

I always get an error message when I put my data fields on my report (.rpt) file : "Error while loading database informations"...

Please Help !!

Yes, the DataSet is filled and I can see its content as needed or even write it to an xml.

I think this is a similar problem, and might provide a solution:

Err Msg: "Failed to load database information"

What version of Crystal Reports are you using?

Well thank you,
I was almost sure it was a programming problem, but I re-installed properly some of the dll's (including Crdb_ado.dll, which I think was of a different version or something else) and it worked !!!

You won 250 points Bob, thanks again !
