Using C# to Add ODBC System DSN to Connect to System ODBC DatasourceHow to add an ODBC System DSN data source on the fly with C# without having to enter Windows Control Panel to configure DSN manually.
This snippet creates a wrapper function to the Microsoft ODBC interface to add ODBC System DSN. You can extend this to include other database drivers in addition to MS Access 2000.
What is ODBC System DSN?
ODBC stands for Open Database Connectivity and is a standard interface for accessing database management systems. ODBC allows applications to access many different database implementations without writing special code for each one.
