shell integration

Ok here is the deal, I have made a program that uses Microsoft agent, I got fed up with all the other ones out there that did not do what i want. I do not want a windows ( i have got that done) i do not want something other than the Characters little icon. and all i want it to do is read the clipboard. I have all that is listed done now. but i would like to add one last thing. I want shell integration. so when i slect some text in explorer (or anywhere elce if i can ) and have the option to "read" there, and then have the slected text passed to my program as a string. when i have it in a string and my program can see it,i can make it play, but i need help wiht the shell integration part.

Thanks all to that read.

And Thanks more to that help me. :-)

I was thinking there was a api command or something like that. :)
