I tried the above code. I have one Windows Form and a single Crystal report file (cr.rpt) in my project folder. I'm using Oracle 10G as the database. But I'm getting an error saying that "Logon Failed". ([Error Description]Image: http://pho.to/Zv6t)

Pls do help.

Finally found the solution from here

The only thing is, I need to set Database credentials at runtime for the Crystal Report to work fine.

cryRpt.SetDatabaseLogon("user", "password", "server", "database")

This usual problem happens only to the Older version of CrystalReports caller from VB to .Net world.

Nothing to worry. Please use like this.........

connectionInfo.DatabaseName = "MahendrenDataBase"

connectionInfo.ServerName ="SystemDSN";//Create a system dsn.

connectionInfo.UserID = "UID";

connectionInfo.Password="Pwd"
