calling a dll from excel macro

[Stefan]

I'm trying to call a function from a dll in an excel macro, however,
every time I run the macro Excel crashes with no explanation why...
The function excepts three strings, does an encryption and returns a
string back..

any ideas of what I'm doing wrong? I must have some fundamental
errors...

thanks.

I guess it would have been helpful to post the declaration of the DLL
function and the call you are making to it, and tell us the version of
Excel and the address at which it crashes.
