Crystal report -- invalid log on parameter error - crystal-reports

Question

I have a crystal report which was working fine on my local machine but when I moved it to my server it's giving me a "Incorrect Log on parameters".
Code is below. It's called from a .net application
Dim CR As New ReportDocument
Dim str As String = Application.StartupPath
If PrintDialog1.ShowDialog() <> Windows.Forms.DialogResult.OK Then Exit Sub
CR.Load(Application.StartupPath & "\CR Reports\BookPickByConsignee.rpt")
CR.SetParameterValue("param_picknumber", Me.txtpickNumber.Text.Trim())
CR.DataSourceConnections.Item(0).SetConnection(Configuration.ConfigurationSettings.AppSettings("DatabaseServer").ToString(), Configuration.ConfigurationSettings.AppSettings("DatabaseName").ToString(), Configuration.ConfigurationSettings.AppSettings("UserName").ToString(), Configuration.ConfigurationSettings.AppSettings("Password").ToString())
'CR.DataSourceConnections.Item(0).SetLogon("sa", "pwd")
' CR.SetDatabaseLogon("sa", "pwd")
CR.PrintOptions.PrinterName = PrintDialog1.PrinterSettings.PrinterName
CR.PrintToPrinter(Me.txtCopies.Text, True, 1, 100)
CR.Close()

You can use the following code to apply certain connection details for a report at run time.
Sorry, code in c#.
Please use that method just after loading report rpt file, instead of CR.DataSourceConnections.Item(0).SetConnection and pass required connection details to method, it will work.
public static void CrystalReportLogOn(ReportDocument reportParameters,
string serverName,
string databaseName,
string userName,
string password)
{
TableLogOnInfo logOnInfo;
ReportDocument subRd;
Sections sects;
ReportObjects ros;
SubreportObject sro;
if (reportParameters == null)
{
throw new ArgumentNullException("reportParameters");
}
try
{
foreach (CrystalDecisions.CrystalReports.Engine.Table t in reportParameters.Database.Tables)
{
logOnInfo = t.LogOnInfo;
logOnInfo.ReportName = reportParameters.Name;
logOnInfo.ConnectionInfo.ServerName = serverName;
logOnInfo.ConnectionInfo.DatabaseName = databaseName;
logOnInfo.ConnectionInfo.UserID = userName;
logOnInfo.ConnectionInfo.Password = password;
logOnInfo.TableName = t.Name;
t.ApplyLogOnInfo(logOnInfo);
t.Location = t.Name;
}
}
catch
{
throw;
}
sects = reportParameters.ReportDefinition.Sections;
foreach (Section sect in sects)
{
ros = sect.ReportObjects;
foreach (ReportObject ro in ros)
{
if (ro.Kind == ReportObjectKind.SubreportObject)
{
sro = (SubreportObject)ro;
subRd = sro.OpenSubreport(sro.SubreportName);
try
{
foreach (CrystalDecisions.CrystalReports.Engine.Table t in subRd.Database.Tables)
{
logOnInfo = t.LogOnInfo;
logOnInfo.ReportName = reportParameters.Name;
logOnInfo.ConnectionInfo.ServerName = serverName;
logOnInfo.ConnectionInfo.DatabaseName = databaseName;
logOnInfo.ConnectionInfo.UserID = userName;
logOnInfo.ConnectionInfo.Password = password;
logOnInfo.TableName = t.Name;
t.ApplyLogOnInfo(logOnInfo);
}
}
catch
{
throw;
}
}
}
}
}
