How about a timer component?, or counting the data then saving it?.

no problem at all.. y can't u count the received data .? i presume u know how to open a file (or is that the question

ops: ?) it would be better to buffer the entire data first (for 10 receives) then flush them to file , rather that (opennig and ) writing at each receive.

If your are having trouble with VB, maybe look at powerbasic.com, the PC/CC program is more like a DOS console program.

not clear what u intend ..
replace label1.text to text1.txt
the file open command is like file number = Open <filename> <filemode> , u may have to refer msdn

receiving is as simple as (taken from working program):

Code:

Private Sub MSComm1_OnComm()
  Text1.Text = Text1.Text + MSComm1.Input
End Sub

but the most common problem is that people forget to change Rtreshhold to 1. Default value of 0 means no received characters would be returned to program. To change this setting go to MSComm properties...
