appending LOWORD(lParam) to string

How can I append a LOWORD(lParam) to a string ( it's of type string not char *)

I'd convert the LPARAM to a 'char *' using itoa() and then work from there. I'm not familiar with 'string' types so I can't help you there.

sprintf or ostringstream

Thanks alot for reply, I think I'll stick with sprintf().
