Re: GetExtension not working

[User (Legacy)]

Actually, it looks like raw_GetExtension receieves a char pointer (LPSTR), 

not a BSTR. 

I tried just about everything: CString, BSTR, character array, etc. and I 

always got the same error code. I copied in the code Josh posted verbatim 

and I still got the same thing. I created a small sample app and tried 

everything but with no difference in results (the code I used is at the end 

of this e-mail.) 

I'm stumped. I've got all the latest versions of the DLL's registered. 

(I'm acutally trying to use GetExtension as a workaround for another problem 

I'm having. I'll post that problem in a new thread...)
