Hello Experts

I am very new in Mobile Programing. I used "asmscntrl.dll" for sending sms in my own mobile. but i need some code like:

- My phone is attached with my pc
- My friend make a call (which number is saved in my mobile) in my moblie or send a message
- My vb program will automatically recieve his call and send feedback message to my friend's mobile.

How can i do that by "asmscntrll.dll" or if i need any other resource plz reply...
