Shashank, Thanks for replying and for the thread pointers. I'm not sure if the code snippets are exactly what I need or not, since I'm not sure exactly what I need. But, I would be interested to see the code you offered. Thanks for providing me with a place to start! Also, can you recomend any Framework(s)? I have no experience with tthem...
