Message: Data source name not found and no default driver specified
Explanation:
If you are connecting via the String tab and you have not specified a DSN, make sure to specify a DRIVER.
If you are connecting via the String tab and there is a space ahead of the DRIVER parameter, try removing it. Certain versions of SQL Anywhere have a problem with that.
If you are connecting via the String tab and you have specified a DSN, make sure it exists.
If you are using the 64-bit version of SQL Anywhere to run Foxhound, check to see if the ODBC DSN for the target database only works with the 32-bit version of SQL Anywhere, or vice versa.
Also check for the message "The specified DSN contains an architecture mismatch between the Driver and Application".
