>I need to fill a combobox with the system DSN's. I can use a win32 API or walk the registry. Anyone have any advice on this? Not sure what API to use to do this but I do see the values in HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBC.INI\

...and the API will walk the registry...

the only concern is that it will not pick up User DSNs this way - there are separate API calls defined for each type of DSN, which correspond to different locations in the registry.
