    Hey guyz,

    I'm using the MSComm component in VB for communication with a serial device. The serial device operates on hex commands. I've tried adding a text field to my app. and directly writing in the hex commands. The problem is when I enter the following hex value:

    010A00000000020108F7

    VB sees this as a string and not a series of hex values. Does anyone know how to convert from the Hex string to the actual hex value in VB

    Any help appreciated,
    thanks

    Maybe you need to Dim a string and each hex byte you want to send, you need to convert it to a character and add it to the string.

    Dim sCommand as String

    'To put the command 01 0A 00 into the string..

    sCommand = sCommand & Chr(&H01)
    sCommand = sCommand & Chr(&H0A)
    sCommand = sCommand & Chr(&H00)

    then set the data for the comm control to sCommand.
