    CHR(&H00) vs. CHR$(&H00)

    In VB6, I use CHR$(&H00) to create a Null Character.
    In VB.Net VS2008 CHR(&H00) creats a Null.
    I'm trying to send a Hex(00) to a serial device, but the VB.Net function only sends a null, not a null character.
    How can I accomplish this with VB.Net?

    Use ControlChars.NullChar constant.
    #define true ((rand() % 2)? true: false) // Debug THAT!

    As I've said on a different forum, ControlChars.NullChar will not give any different result because a null character is a null character. The issue lies elsewhere, probably with string handling.

    Send 0x00 byte instead?
    #define true ((rand() % 2)? true: false) // Debug THAT!
