Illustrator Macros/Scripting

Hey guys is it possible to create macros in illustrator, or how would this be achieved via the scripting.

Basically i have a c# application that contains alot of pictureboxes all with images in them. i want to be able to right click an image and select vectorise. Which will send the image to illustrator live trace the image, resize it, then copy the resulting image back into my c# app.

How would this be best done

thanks
