Expert Advisor to VB.NET DLL

Hi,

I'm a vb.net coder so simply looking for a sample VB.NET library/DLL that can connect to MT4.  The VB.NET Library needs 3 functions connected to the ExpertAdvisor:  

A function to receive each tick into the DLL (so i can then log the information into my database)

A function that either checks the DLL for Orders to execute each tick / or the ability for vb.net to send an order to be executed in MT4 (either or?)

A function to either check the DLL for open orders to close each tick or for the DLL to send an instruction to close an open order.

Thanks! 

Andrew
