inukisoft, el siguiente código me ha servido ene veces para hacer lo que tu deseas, esta hecho en VB 6.0, pero debes compilarlo como DLL, luego Registrarlo en IIS 4.0 o 5.0 da lo mismo.
Espero que te sirva, si no envíame un email y te paso el código.
es mas simple de lo que imaginas, tranquilo.

Acá va el código del Form
