Hi,
there is a crystal report and a .net application.
The report is added to the application.
There are fields of my dataSet on the report.
When I open the report with CR and click the "Preview" of my page I get this message:
"ADO.net(XML): Please enter connection information ... "
There are two possibilities: the visual studio data class name or browse the xsd- file.
When I choose the vs dataclass (ApplicationName.DataSet) I get an error message: Logon failed. Details: Object reference not set to an instance of an object"
When I browse the the xsd-file and I click "finish" it's okay.
But the problem is: there is a database field (of my dataSet), that is empty. In my application I can show this database field with a dataGrid or a MessageBox- without problems and with the correct value.
But why doesn't print in the report?
Thank you for your help!
