It does not seem to be working.
Here is what I have:
Myshell.DataAvailable:
Window1.outEdt.Text = Window1.outEdt.Text + " " + Me.ReadAll
Myshell.Completed:
Window1.StateLbl.Caption = "State: Complete"
RunBtn.Action:
Dim S As New Myshell
S.Mode = 2
StateLbl.Caption = "State: Running"
s.Execute "Writer"
Writer writes the numbers 0 to 20 to stdout at .5 second intervals.
When the Run button is clicked, StateLbl changes to "State: Running" but
nothing else happens. It appears that neither Myshell event is firing.
(I've put breaks in them which are never reached.)

This is what the Shell is for. You can open an Interactive shell (Mode
= 2), start your tool and monitor the Shell's DataAvailable and
Completed Events to accept the data from the tool's stdout (and even
send to the tool over stdin if needed) and display it however needed.
Create a new Shell Class called myShell in your project Add an instance
of myShell to your main window (now called myShell1 or you can rename
it) Select the myShell1 instance and change the mode to 2 Check the
Events for myShell1 and you will see the "DataAvailable" and "Completed"
events.
Add Code to the DataAvailable event to catch and process your tool's
stdout output.
Add Code to the Completed event that handles the tool's finishing and
exiting In your main window, call myShell1.Execute "the tool command and
args"
This should get you what you're looking for unless your tool is running
and you're trying to attach to it. In that case, you might try
redirecting stdout to a file in your tool, using a Shell and executing
"tail -f /tmp/the_stdout_file" as the Shell's command instead of your
tool and then using the same info above.
