Dear friends, good morning, I am a newbie in VB.net and I am developing an application that extracts records from an Excel file (I do not use conventional databases). I have come to store the information of these Excel records in a table of a Dataset. I need to know how to dump the data from the "Client" table of the Dataset " Base.xsd " to the report previously created / configured with Crystal Reports. The report is called rptCartas.rpt and as I mentioned it I have assigned the corresponding fields (from the Customers table, from the Dataset) in its respective place within the report. Attached picture of my code and the error message: thanks for any help.
