One problem: if the user doesn't have riched32.dll installed, it won't work.
I just tried it and it failed...

See the WIN32 reference, wich windows version do you have?

You missed my point, which is that your app is going to have
to check that riched32.dll is installed. That is, you can't
just assume that it will be on all systems, even if it does
get installed with Windows. Remember that files can get
corrupted or deleted by users by mistake...

ah, ok.
well, this was just an example not an application...
however, yes, in a real application every one has to look for every external file before calling it

I hope I didn't offend you... I was just pointing that out for
the benefit of any lurkers here, that's all.

Good work Ricardo!
Question:
you load a DLL with: LoadLibrary_("RICHED32.DLL")but you don't use the
'FreeLibrary_("RICHED32.DLL")' command at the end of your code.

Is this not needed? I'm worried about memory leaks.

Have a nice day...

This is not necessary as an application ALWAYS free unnucessary stuffs at end (Thanks to Windows)..
