>>In the function declaration, does it return a BOOL or a DWORD. If it's a BOOL then 0 does indeed mean that the function failed. However, many functions return 0 (ERROR_SUCCESS) if they're not returning handles, etc.

But I want to be able to programmatically create the DSN if it does not exist on a user's computer. I have been able to check successfully for the existence (or not) of a DSN.

Without the declaration, it's pretty much of a guess, unless there's an error that a function like GetLastError() would return. Quite possibly it's expecting so of those values to be passed by reference rather than value. That might cause it as well.
