Simple MathLink question

Hi all,

I have never written anything that uses MathLink and was wondering if
someone who has done so could share it.

I have Mathematica 3.0.1 and use MicroSoft Visual C++ 6.0.

I will be teching a course which uses Mathematica for demonstration and
would like to include such an example.

Any ideas?

Also, has anyone done any engineering type applications with Mathematica
in areas of signal processing, image analysis or general engineering
and science applications that they would be willing to share?

Sorry for the long wishlist.
