Thanks to you too Tim,
Unfortunately your solution doesn't work either. The shell never quits
running, and no events are fired either.
I tried instantiating in code, or by adding the class to a window, but
neither seem to work.

Hi all,
I need to execute a small program, using RB's Shell class. This program
can read its data either from file or from stdin.
I would really like to have it read from stdin, but the problem is this:
when it executes without the name of a file on the command line, it just
sits there, waiting for input from stdin. There's no output to catch in
order to know when to execute the shell.write command, and doing this:
shell.execute "thatfile.exe"
shell.write "some text to be processed"
...obviously does not work
Is there someone who can give me a hint?
Hi Ronald,
First - make sure the Shell's Mode is 2
Second - since you seem to be on Windows, set the timeout value to -1
Third, use the much maligned App.DoEvents() to pause without bogging the
interface
Dim myShell As New Shell
myShell.Mode = 2
If TargetWin32 Then
myShell.Timeout = -1 // Not required if not Windows
End If
myShell.Execute "thatfile.exe"
App.DoEvents(1000) // wait one second - may need to adjust
myShell.WriteLine "some text to be processed"
Do
App.DoEvents(10)
Loop Until Not myShell.IsRunning
// Handle results here...
Since I created the myShell instance in code in this sample instead of by
dropping a Shell class into our project, we don't have easy access to the
"Completed" event. Thus the Do ... Loop Until to monitor the
myShell.IsRunning flag. If you do add a Shell to your project in the IDE
and then subclass it, you won't need the Do ... Loop Until as the
Completed event will fire when the execution completes and you can put
your finish up code inside of that event.
HTH,
Tim
