Full Threaded Shellicious
I couldn't resist adding some features to Shellicious. You can now run shell commands either asynchronously (as before) or synchronously, like so:
Private WithEvents _s As New Shell Private _IsExecutionComplete As Boolean = False Public Sub Main() _s.UseNewThread = True _s.Execute("C:LongRunningConsoleApp.exe") Do While Not _IsExecutionComplete '-- do other work here.. Thread.Sleep(20) Loop Console.WriteLine("Exiting Sub Main()..") Console.ReadLine() End Sub Private Sub OutputLine(ByVal LineText As String) Handles _s.OutputLine Console.WriteLine(LineText) End Sub Private Sub ExecutionComplete(ByVal TimedOut As Boolean) _ Handles _s.ExecutionComplete _IsExecutionComplete = True Console.WriteLine("execution complete; did we time out? " & TimedOut) If _s.ExitCode <> 0 Then Console.WriteLine(_s.Error) End If Console.WriteLine(_s.ExecutionTime) Console.WriteLine(_s.ExitCode) End Sub
I updated the code in the original post. And this time I remembered to give the threads names, which always helps in debugging:
The thread 'ShellErrorThread' (0xca4) has exited with code 0 (0x0). The thread 'ShellOutputThread' (0x934) has exited with code 0 (0x0). The thread 'ShellLaunchThread' (0x5c0) has exited with code 0 (0x0).
So far so good. The synchronous behavior respects the same .MaximumWaitSeconds property as before, and there's a new .CancelExecution method if you want to bail out on demand.
