Hi Plamen

I guess this is the issue described here:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclang/html/vclrfstringliteralshavepropertypeofconstchar[].asp

Interestingly at this link ...
http://support.microsoft.com/default.aspx?scid=%2Fservicedesks%2Fwebcasts%2Fen%2Ftranscripts%2Fwct032003.asp
... it says "You need to compile this code at a command prompt without
using any specific compiler switches" - but you tried that and it
didn't fix the problem - I assume that that unofficial document is out
of sync with your version of VC7.1.

I think it should be straightforward to refactor the TempStr function
to not use string literals, I'll look into this and get back to you.

Eric
