Invalid log on parameter

[lutzs]

Hi,
there is a dataset in my application. I add a column of this
dataset in my crystal report.
I start the program and I will print this report. I get this error message by click the button:
"Unable to connect: invalid log on paramter"

The error is in line:
oRpt.PrintOptions.PrinterName = @"\\PRINTER";
oRpt.PrintOptions.PaperSource = PaperSource.Auto;
oRpt.PrintOptions.PaperSize = PaperSize.PaperA4;

ReportDocument crReportDocument = new ReportDocument();

// this is the report with the dataset column
crReportDocument.Load("C:\\header.rpt"

// this is the error-line
crReportDocument.PrintToPrinter(1, true, 1, 1);

// print another report
oRpt.PrintToPrinter(1,true,1,1);


What can I do?
There exists a database connection.

Thank, Stephanie

Are you passing the Report (and it's Database Tables) appropriate LogOn information.
I've dealt with the generation of a number of Crystal reports through code (Delphi and C#) that run against a SQL Server database.
In order to load data into the report you need to prep the information required to log on successfully to the database / tables (ie. server-name, database-name, user-name and password).
I hope that this sets you off in the right direction.
