Visual BAsic communications with a microcontroller

Can anyone please teach me how to communicate to a microcontroller particularly with ATMEL89S52 and PIC16F877 using Visual Basic or Java.

Some websites and articles on the web can be useful also so if you happen to know one,kindly refer it to me.

Thank you in advance!!!

Just started working on this myself. heres some goodies to get you started.
