Remy, I have the same problem as schandler, and I tried your solution
although the problem now is that I get ONLY the text entered through my
application windows and I can't capture any text entered through any other
running application, so please find below my code for the dll and my project
and please let me know what exactly I am doing wrong...

Regards
