Hi kindly include database logon paramets so every time your code is executed it will be automatically logged in.

Try
 
MyCommand.Connection = cn
MyCommand.CommandText = "SELECT * FROM maintable where irsno=" + irsn
MyCommand.CommandType = CommandType.Text
myDA.SelectCommand = MyCommand
myDA.Fill(myDS, "maintable")
 
myDA.SelectCommand.CommandText = "Select fullname from usertbl where username='" + Login.txtuser.Text + "'"
myDA.Fill(myDS, "usertbl")
 
myDS.EnforceConstraints = False

'''''INCLUDE THIS'''''''''''''''''''''''''''''''''''''''''''
rpt.SetDatabaseLogon("database_name", "database_password")

rpt.SetDataSource(myDS)
CrystalReportViewer1.ReportSource = rpt
'rpt.PrintOptions.PrinterName = "EPSON LX-300+ /II"
'rpt.PrintToPrinter(1, False, 0, 0)
Catch Excep As Exception
MessageBox.Show(Excep.Message, "Error", MessageBoxButtons.OK,
MessageBoxIcon.Error)
End Try
