    Bit masking problem

    I am trying to bit mask the first 6 bits of a byte (8 bits) so the binary looks like 00000011 which I think is &3 ( in hex).

    It says here that you just use the AND operator and then the hex.
    I am using this:
    Dim VPCuff1 As Integer = (buffer(2) and &3) * 256 + buffer(3)

    buffer() is a byte array (0-15 bytes). I get an error on the: &3 (hex part). When I use something like &HFF00 it doesn't give me an error.

    Any thoughts???

    I don't think &3 is valid... perhaps &H3. ???
