CR11R2: two Databases - doesn't work

Question

Hi!
I've developed a CR-Viewer with .NET 2.0 and CR11 Release 2. The Viewer works fine with reports which have only one datasource (ODBC) with one database. But a few reports of us have one datasource with two databases.
The first database-Name is IMS and the second fibgs.
Our Viewer needs to update the Connection (ODBC-Name, Database-Name, DB-User and password) for each table.
The info of table.LogOnInfo.ConnectionInfo.DatabaseName is always IMS and thats not correct. The tables/views which are in the database fibgs aren't available after the Datasource was updated.
So my question is: How can I get the correct Database name of each table. (In Crystal Reports the correct name is shown).
Thanks a lot!

Hi!
Thanks! But my problem is, to find out which table is part of which database. I've already have two datasources. Here my code, perhaps it is better to understand:
foreach (CrystalDecisions.CrystalReports.Engine.Table tbl in cr.Database.Tables)
            li = tbl.LogOnInfo;
            string oldDbName = li.ConnectionInfo.DatabaseName.ToUpper();
            if (oldDbName.Length >= 2)
                //Here is the problem => always IMS!!!
                if (oldDbName.Substring(0, 3) == "IMS") 
                    // IMS-Table
                    try
                        li.ConnectionInfo = p_ImsCi;                       
                    catch (Exception ex)
                        MessageBox.Show("Fehler bei der Zuweisung der
iMS-Verbindungsinformationen bei
Tabelle " + tbl.Name + "." + Environment.NewLine + ex.Message);
                else
                    // GYPSILON-Table
                    if (p_GypCi.DatabaseName != "" & p_GypCi.ServerName != "")
                        try
                            li.ConnectionInfo = p_GypCi;                           
                        catch (Exception ex)
                            MessageBox.Show("Fehler bei der Zuweisung der
Gypsilon-Verbindungsinformationen
bei Tabelle " + tbl.Name + "." + Environment.NewLine + ex.Message);
                    else
                        MessageBox.Show("Die Logon-Informationen für die
FiBu-Datenbank sind unvollständig.",
"iMS Report Viewer", MessageBoxButtons.OK, MessageBoxIcon.Information);
                        return false;
                // Nun weisen wir li wieder der Tabelle zu
                try { tbl.ApplyLogOnInfo(li); }
                catch (Exception ex)
                    MessageBox.Show(tbl.Name.ToString() + " " +
ex.Message + Environment.NewLine +
"(ApplyLogOnInfo->" + tbl.Name + " )");
            else
                // Alter Datenbankname hat weniger als 3 Zeichen -> FEHLER
                MessageBox.Show("Die Logon-Informationen für folgende
Datenbank sind unbekannt: '" + li.ConnectionInfo.DatabaseName +
"' '" + li.ConnectionInfo.ServerName + "' '" +
li.ConnectionInfo.Type + "'", "iMS Report Viewer",
MessageBoxButtons.OK, MessageBoxIcon.Information);
                return false;
            //check connectivity
            bool StatusConnectivity = false;
            try
                StatusConnectivity = tbl.TestConnectivity();               
            catch (Exception ex)
                MessageBox.Show("Fehler bei der Verbindungsprüfung." +
Environment.NewLine +
ex.Message + " -> " + tbl.Location + "(" +
tbl.LogOnInfo.ConnectionInfo.DatabaseName + " " +
tbl.LogOnInfo.ConnectionInfo.ServerName + ")" +
Environment.NewLine);
We've got about 300 reports and a couple of them have two databases in one ODBC-Connection.
Any other idea? Thanks!!!
