asp.net webservice (c++) linking dll problem

Hello,
I am writing a webservice for some older c++ classes.
I build these unmanaged classes as a dll,
and in my webservice I add a reference to this dll.
I include the necessary headerfiles, and when I call a function from my
old project, everything compiles and links fine.

When I debug, I can see the webservice-functions in my browser,
but they don't work when I invoke them... (The page cannot be displayed)

Are there any restrictions on the dll you use?

When using a .lib, I get the same problems...
thx in advance
