I would advise that you create your dataset with vb.net and just pass it to the crystal report.  

It's possible to create a crystal report that connects to oracle, but if your results are based on user values that's going to be more difficult or impossible (depending on the specifics) to do.  It will be much more efficient to handle the user values in your application and send the completed dataset to crystal.

Here's a walkthru for doing this: http://support.businessobjects.com/communityCS/TechnicalPapers/rtm_reportingoffadonetdatasets.pdf.asp

Query Engine Error can mean just about anything.  

Make sure your dataset is being populated correctly - maybe attach it to a datagrid or something to verify that the correct data is being pulled in.

well...i can't prove much but with the same steps on a different type of database, such as Access

i can pull everything out correctly, into the crystal report without any errors. so, i doubt that the dataset has any problems in it.

Are you using the Oracle provider to access your Oracle database?

Not the OleDb provider, the OracleDataAdapter, OracleCommand, OracleConnection, etc.

Do you have Visual Studio.NET 2003?  It has the OracleDataAdapter.

Okay, back to business.

What was the full error when you tried to connect Crystal Reports to the dataset?
