Can't get GetDllDirectory() to work?

Can't get GetDllDirectory() to work?

Can't get GetDllDirectory() to work?

(OP)
Hi again,
Now that I can get my program to compile, I always get 0 returned from GetDllDirectory() and the string parameter is an empty string.  When I do GetLastError() it reports "The operation completed successfully".

If I replace the GetDllDirectory() with GetModuleFileName(), it actually returns the whole path & filename of the executing program.

So:
1.  Why is GetDllDirectory() returning 0 (meaning an error), but then GetLastError() says everything is fine?
2.  Why am I getting back an empty string instead of something like "C:\Program Files\..."?

RE: Can't get GetDllDirectory() to work?

What OS?

You must call SetDllDirectory first.
In MSDN:
The GetDllDirectory function retrieves the application-specific portion of the search path used to locate DLLs for the application.

For detail.
Look for GetDllDirectory and SetDllDirectory in MSDN.

Too late for the program I was writing, but good to know.  Thanks.
