Using ApplyLogOnInfo (lost information)

Question

Hi.
I am using:
Crystal Reports 2008 ver. 12.0.0.683(sp0)
Visual studio 2005 (vb)
SQL2005 & Oracle (db)
The problem is that when the following line is executed, the database name and all information reverts back to the original information (database name,etc) .
(when i try to change connection SQL to Oracle db, and Oracle to SQL).
crTable.ApplyLogOnInfo(crTableLogOnInfo)
Vb code:
Dim crTableLogOnInfo As New TableLogOnInfo
Dim crConnectionInfo As CrystalDecisions.Shared.ConnectionInfo = New
CrystalDecisions.Shared.ConnectionInfo()
With crConnectionInfo
    Select Case intProvider
    Case databaseProvider.sqlServer
            .ServerName = "server"
            .DatabaseName = "DB"
            .UserID = "sa"
            .Password = ""
    Case databaseProvider.Oracle
            .LogonProperties.Clear()
            .Attributes.Collection.Clear()
            'setup the attributes for the connection
            dbAttributes.Collection.Set("Server", "ORCL")
            dbAttributes.Collection.Set("Trusted_Connection", False)
            .ServerName = "ORCL"
            .DatabaseName = ""
            .UserID = "us"
            .Password = "pwd"
            .Attributes.Collection.Set("Database DLL", "crdb_oracle.dll")
            .Attributes.Collection.Set("QE_DatabaseName", "")
            '.Attributes.Collection.Set("QE_DatabaseType", "Servidor de Oracle")
            .Attributes.Collection.Set("QE_SQLDB", True)
            .Attributes.Collection.Set("SSO Enabled", False)
            .Attributes.Collection.Set("QE_LogonProperties", dbAttributes)
            .LogonProperties = dbAttributes.Collection
            .Type = CrystalDecisions.Shared.ConnectionInfoType.CRQE
        End Select
    End With
For Each crTable In crTables
    crTableLogOnInfo = crTable.LogOnInfo
    crTableLogOnInfo.ConnectionInfo = crConnectionInfo
    crTable.ApplyLogOnInfo(crTableLogOnInfo)
next*
Don't return error, ApplyLogOnInfo.

Understood re. the actual issue. However I wonder if what you asked in the other post may be a clue to the solution. E.g.;
When I save the report,(cr designer new connection Oracle), after 90% dont't have problems
when i use the report on my application.
Please elaborate on the above. Are you trying to say that this work 90% of the time and fails 10% of the time? If that is so, then that is quite different than the report reverting to an incorrect conenction.
Do you now something about OracleReport() ¿? (Crsytal library¿?)
Again, what does the above mean?
