    Passing Hex values


    He All,

    How can I pass hex values as string into a function.
    For example I want to pass (5A C9 02)(any number of) as a single string,
    where the receiptant is a string variable

    Thanks in advance
    Suneera

    Suneera, You can use the hex function to convert a number into a string of
    hexadecimal digits. Hex(5949698) will return the string "5AC902". Hope
    this helps! --Sam

    If I understand correctly...

    Dim s As String
    s=Chr$(CLng("&H5A")) & Chr$(CLng("&HC9")) & Chr$(CLng("&H02")) ...
    Call MySub(s)

    If you have control over the called routine I'd suggest changing it to a
    byte array instead. Strings in VB are stored as unicode so you are
    converting ascii->unicode->ascii and that slows things down and can lead to
    some strange issues like:
    If chr$(130)<chr$(255) Then Msgbox "you never get to this!"
