Hi,
I have a .NET 1.0/VS 2003 application with Crystal reports that uses a MS Access DB. I'm migrating it to .NET 4.0/VS2010. The 32-bit application works fine, but the 64-bit doesn't. To begin with, I found out that the OLE DB driver that I used doesn't (and wont) exist in 64-bit version, so I installed the recommended "Microsoft Access Database Engine 2010 Redistributable". Windows forms application succesfully connects to DB, but Crystal Reports doesn't - any attempt to display a report in the report viewer component fails with the message "Failed to load database information...". I attached the screenshot, along with CR debugging files.
Here is the code I use to connect Windows forms to the database (the old connection is commented out):
ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Password="""";" + //@"Provider=Microsoft.Jet.OLEDB.4.0;Password="""";" + @"User ID=Admin;Data Source=" + DatabasePath + ";Mode=Share Deny None;" + @"Jet OLEDB:Database Password=""my_password""";
This is the code I use to connect CR to the database:
foreach (Table t in rpt.Database.Tables)
{ TableLogOnInfo logOnInfo = new TableLogOnInfo(); logOnInfo = t.LogOnInfo; ConnectionInfo connectionInfo = new ConnectionInfo(); connectionInfo = logOnInfo.ConnectionInfo; connectionInfo.DatabaseName = DatabasePath ; connectionInfo.ServerName = DatabasePath ; connectionInfo.Password = "my_password"; t.ApplyLogOnInfo(logOnInfo);
} .lyLogOnInfo(logOnInfo);
I must say that due to the lack of documentation I'm not sure if the second piece of code is correct (beyond that it works fine on 32-bit OS) and which DB driver it uses.
I'd appreciate any help (other than to change the DB, which is not possible at the moment).
