I have read several questions in StackOverflow about redirecting output/errors from application but It could not help me.
I have developed an executable in C# code. It recovers software from system registry and call a webservice to save it to our database.
Inside the executable we are printing messages with
Console.WriteLine("Message from Executable");
On the other hand we have a CRM application and I have written two win forms that call psexec.exe with the desired parameters and this .exe is remotely copied and launched on target machine.
If you use direct psexec call with that parameters in cmd.exe, we can see the psexec execution banners and OUR executable output
Something like:
PsExec v1.98 - Execute processes remotely
Copyright (C) 2001-2010
Mark Russinovich Sysinternals - www.sysinternals.com
Enterprise software @ 2012
Message from application
Starting task in machine "XXXXXXX"
Recovering software list from registry
Program.exe exited on MACHINE with error code 0.
When I make the psexec call with .NET, I cant recover my application output, It just shows:
PsExec v1.98 - Execute processes remotely
Copyright (C) 2001-2010
Mark Russinovich Sysinternals - www.sysinternals.com
Program.exe exited on MACHINE with error code 0.
I am assigning to Process class a delegate who is recovering async data from process, but this information, is not there.
I paste some code to see If you can find the reason my C# Console application output does not appear:
The command I launch is:
Dim CmdExe As String = "\\#MAQUINA# -u #USUARIO# -p #CLAVE# -s -c -f """ + executionPath + """"
Parametes -s (Run as system) -c (Copy local file to remote system) -f (force overwrite)
Private Sub LanzarProceso()
CheckForIllegalCrossThreadCalls = False
Dim Proceso As New Process
AddHandler Proceso.OutputDataReceived, AddressOf CallbackProcesoAsync
AddHandler Proceso.ErrorDataReceived, AddressOf ErrorDataReceivedAsync
Dim startInfo As New ProcessStartInfo
startInfo.FileName = execFile
startInfo.Arguments = CmdExe.Replace("#MAQUINA#", txtFiltroMaquina.Text).Replace _
("#USUARIO#", txtUsuario.Text.Trim).Replace _
("#CLAVE#", txtClave.Text.Trim)
Proceso.EnableRaisingEvents = True
startInfo.UseShellExecute = False
startInfo.RedirectStandardOutput = True
startInfo.RedirectStandardError = True
startInfo.CreateNoWindow = False
Proceso.StartInfo = startInfo
Proceso.Start()
Proceso.BeginOutputReadLine()
Proceso.BeginErrorReadLine()
Proceso.WaitForExit()
End Sub
Delegates handling data:
Private Sub CallbackProcesoAsync(sender As Object, args As System.Diagnostics.DataReceivedEventArgs)
If Not args.Data Is Nothing AndAlso Not String.IsNullOrEmpty(args.Data) Then
If Not listtask.InvokeRequired Then
listtask.Items.Add(args.Data.ToString)
Else
Dim d As New TextToControl(AddressOf AddToControl)
listtask.Invoke(d, args.Data.ToString)
End If
End If
End Sub
Private Sub ErrorDataReceivedAsync(sender As Object, args As System.Diagnostics.DataReceivedEventArgs)
If Not args.Data Is Nothing AndAlso Not String.IsNullOrEmpty(args.Data) Then
If Not listtask.InvokeRequired Then
listtask.Items.Add(args.Data.ToString)
Else
Dim d As New TextToControl(AddressOf AddToControl)
listtask.Invoke(d, args.Data.ToString)
End If
End If
End Sub
I checked the program is finishing correctly. THe c# executable has
Enviroment.Exit(0);
at the end of the execution
Ok, the best workaround I found to get all the output between psexec and my c# application after execution is:
Dim CmdExe As String ="\#MAQUINA# -u #USUARIO# -p #CLAVE# -s -c -f """ + executionPath + """ > outputFileCode.txt"
This allow me to parse the standard output without having to change anything or calling my program directly, because I can`t do it.
