I have a C# Windows form application loaded into a becckhoff PLC/PC. The system was designed to have an external SQL server providing the data to generate a Crystal report.
it worked just fine. Now both the server and the application are housed inside the Beckhoff PLC and I can't generate the Report anymore.
It tells me.
Failed to open the connection
database vendor code 17
What should I be looking for in my c# code?
or should I worry about the SQL data base
?
