Yes, it is easy to report from a dataset object (well, it's easy after you do it once or twice...) The first step is to temporarily populate you DataSet with actual data you plan on reporting from. Then save it to an XML Schema file using DataSet.WriteXmlSchema(). Once you've done that you don't need that code anymore.

Next, you want to create the report and for the data source, choose ADO.NET and open the schema file you just saved. CR reads the schema file to determine the fields you want to report from. Finish building your report using this schema file as the data source.

Last, in your live application open the report and pass the fully populated dataset to the report using the SetDataSource() method. CR takes this data and prints it on your report.

Caution: The schema file must match the DataSet exactly. The slightest change will cause CR to not recognize your dataset. If you have to modify the dataset in anyway, then go through the steps to re-create the schema file and have CR read it again using Database | Set Location menu option.

You only need to refresh the scema file if the underlying data structure changes. If you're just loading different data (but using the same fields), then you're okay to just keep passing the new dataset to the report.

Yes, you can assign any value to a text field.

Imports CrystalDecisions.CrystalReports.Engine
Dim MyText as TextObject
MyText = CType(ReportDocument.ReportDefinition.ReportObjects("Text3"), TextObject)
MyText.Text = "'" & ds.Table(0).Row(0).Item(0).ToString() & "'"

Make sure you surround and strings with the single quote, otherwise you get an error because it thinks you are trying to pass it a variable name.
