Sorry, no geniuses here that I'm aware of - just people who have a bit more experience. :)

I'd suggest you look into the MSComm control.

There is one more question,that's i need to display some data from a sensor...so i need to retrive the data from a data packet and the it have divided into three section which are start byte,follow by the byte expecting and lastly follow by the information that i wanted..
the start byte is for differentiate the different level of data...the byte is needed for the first data is 1 byte,follow by 1 byte and lastly is 3 bytes..
how should I do the conversion to make it to become binary ? the start byte address is 0xAA in Hex...

thanks for the helping !! :-)

I'm afraid I didn't really understand the question.

However, this simple routine will convert a byte to a binary string, which may be part of what you need.

Public Function Bin(ByVal ByteValue As Byte) As String
  Dim I As Long, BitValue As Long, BitWeight As Long
  For I = 0 To 7
    BitWeight = 2 ^ (7 - I)
    BitValue = ByteValue \ BitWeight
    Bin = Bin & Format(BitValue)
    ByteValue = ByteValue - BitValue * BitWeight
  Next
End Function
