I assume you mean an ODBC Data Source? If so, all you need to do is
remove the registry keys for it. The IDBC Database is stored in the
Registry. there is one entry in SOFTWARE\ODBC\ODBC.INI\ODBC Data
Sources for each DSN, and the properties are in a key for that DSN at
SOFTWARE\ODBC\ODBC.INI. For User DSN set to Registry.CurrentUser. For
System DSN, set to Registry.LocalMachine.
