i ran into a problem with my Crystal Reports. instead of using the usual Typed Dataset approach, where you use Report.SetDataSource(DataSet), i decided that was too much hastle and it seems faster and simpler just to design the query in the Crystal Reports 'wizard', and then supply parameters and set the record filter appropriately. what i didn't know was that it was insanely complicated to direct the report to a different database path at runtime (such as most users would have in their deployment environment, whether for Access or SQL server).
i was using Report.SetDataBaseLogon("admin", "") etc and all sorts of variations but none of them were working. I kept getting Logon Failed
exceptions. Apparently you need to iterate through each table used in the report and set the source database for each one. Not only that, but neither of the following lines of code has any effect:
Report.Database.Tables[i].SetDataSource("admin", "", DbPath, "")
Report.Database.Tables[i].LogOnInfo.ConnectionInfo.ServerName = DbPath
apparently you have to create a TableLogOnInfo object and use ApplyLogOnInfo() with that on each table.
here is what does work:
TableLogOnInfo t = new TableLogOnInfo();
t.ConnectionInfo.ServerName = dbPath;
for(int i=0; i<rpt.Database.Tables.Count; i++)
