Exporting crystal report as PDF from C# Invalid Credentials

I have been trying for hours to a bit of functionality to work. I am trying to programmatically generate a pdf from a crystal report and email it to a user. I am able to make that work if I choose a crystal report that doesn't require a database connection, but the minute I try to connect to a report when login credentials are required it fails. I have tried countless things such as the SetDatabaseLogon method as well as using the TableLogonInfo class and looping through the tables in the report. No matter what I do I continue to receive the error message below

Logon failed.
Details: 28000:[Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'sa'.Error in File J:\WINDOWS\TEMP\hotpositions {01D7DA6A-BF42-4248-9297-D846B93BFA3F}.rpt:
Unable to connect: incorrect log on parameters.

Here is some of the code below, like I said I also tried the tablelogoninfo method as well to no avail. Please let me know if you see anything glaring. Of course I have modified the actual database info here since it is sensitive. Thanks for any help you can provide

 ReportDocument crystalReport = new ReportDocument();
            crystalReport.Load(Server.MapPath("~/reporttemplates/hotpositions.rpt"));
            crystalReport.SetDatabaseLogon("sa", "password", "servername", "databasename", true);
            CrystalReportViewer1.ReportSource = crystalReport;

            using (MailMessage mm = new MailMessage("aries@ariesdatabase.com", "mporter@nextmedicalstaffing.com"))
            {
                mm.Subject = "Crystal Report PDF example";
                mm.Body = "Crystal Report PDF example";
                mm.Attachments.Add(new Attachment(crystalReport.ExportToStream(ExportFormatType.PortableDocFormat), "Report.pdf"));
                mm.IsBodyHtml = true;
                SmtpClient smtp = new SmtpClient();
                smtp.Host = "localhost";
                smtp.Send(mm);
            }

Does the report have a subreport?

If so you have to do the same for each subreport.

does the report open in the viewer?

there are no sub reports, and it will show in a viewer, but it pops up with the login credential screen asking me to enter. For some reason the code is not passing through the login credentials to the right area, there is some sort of disconnect.

You are setting integrated security ( I believe the last flag = true is for that). Change it to false and try again.

If you want to use integrated security then the easiest way is to remove the code which is setting the connection information and to point the report to use an ODBC DSN file which is using integrated security.

I just switched to false and it still failed with the same error message. That sounded like a good option, unfortunately it still didn't correct the issue. Thanks for the input though.

You may need to set also the location for the tables

Ok so I added a reportviewer and used the foreach statement to credential each TableLogOnInfo in the crystalreportviewer object. That actually worked. How do you apply those same credentials to a ReportDocument object, I believe that is where I am running into the issue, obviously it works for the viewer and that made the difference there so somehow I need to do the same thing to the reportdocument object if possible.

I finally figured it out. I kept trying to use the actual name of the server in the servername field. It actually wants the name of the ODBC Datasource from the control panel.

ConnectionInfo cnInfo = new ConnectionInfo();
            cnInfo.DatabaseName = "databasename";
            cnInfo.ServerName = "dsnodbcname";
            cnInfo.UserID = "sa";
            cnInfo.Password = "password";
            cnInfo.IntegratedSecurity = false;
           
            foreach (CrystalDecisions.CrystalReports.Engine.Table tbl in  crystalReport.Database.Tables)
            {
                TableLogOnInfo logonIfo = tbl.LogOnInfo;
                logonIfo.ConnectionInfo = cnInfo;
                tbl.ApplyLogOnInfo(logonIfo);
            }

Just wanted to share in case someone else ran into this issue
