Extract Weight Value from String

P: 2
I use this code to capture weight from Avery weigher indicator through serial com

Expand|Select|Wrap|Line Numbers
  1.  Private Sub Read_Click()
  2. 'send the Print command and read the weight value.
  3. NETComm6.Output = "p" & Chr(13) 'send PRINT command to the scale.
  4. Dim Buffer As String 'define Buffer
  5.     Buffer$ = Buffer$ & NETComm6.InputData 'wait for the data come into the serial port
  6.     WtInfo = Buffer
  7. End Sub
  8.  
And i got this
80 00 000S99291235 F80 00 000S99291236 E80 00 000S99291237 D80 00 000S99291238 K80 00 000S9929123

How can I extract the 80 kg to my table field

Thank you

You can break that string into its various parts by using the split() function. If that is a space (it might be some other unprintable character) you can do it like this:
Expand|Select|Wrap|Line Numbers
  1. dim Wtarray as variant
  2. dim Weight as integer  // ?? or whatever is right data type
  3. Wtarray=split(WtInfo)
  4. Weight = Wtarray(0)   // assuming the weight is in the 1st position

Thank you for your reply

There is no "80 kg" within the string. If you specify in your question specifically what it is you are trying to achieve then we can help you. I suspect Jim's answer is a more sensible solution than what you're using but without the details you have as to what it is you actually want it's impossible to say.
