R – Crystal Reports 8.5 Concurrent Licenses Issue with vb6

What is the value of your selected variable?

Table.SetLogOnInfo ConnName, DBName, user, pass
DomainName = selected
'Set parameter Fields

If it is not a string, then that might be the problem. Crystal expects a string variable and when it doesn't receive what it expects, it throws errors.

You need to wipe the tables and change the configuration of access to the database, see the example below. In the first line of code I put an example if necessary to change the connection driver, in my case the report was pointing to a PostgreSQL database and programativamente needed change to connect to a SQL SERVER.

myReportObject.Database.Tables(1).DllName = "crdb_ado.dll"       'Connect to SQL with OLEDB
For Index = 1 To myReportObject.Database.Tables.Count
    With myReportObject.Database.Tables(Index)

        .ConnectionProperties.DeleteAll

         .ConnectionProperties.Add "Provider", "SQLOLEDB"
         .ConnectionProperties.Add "Data Source", mySqlIP
         .ConnectionProperties.Add "Initial Catalog", myDB
         .ConnectionProperties.Add "User ID", usr_id
         .ConnectionProperties.Add "Password", pass
         .ConnectionProperties.Add "Integrated Security", 0

    End With
