I run a command with psexec, but I need to keep the command window open, or redirect the output to a variable.  Here is the code I have, what can I do to make that happen?

 Private Sub Button23_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button23.Click
        '*********sys info button********************************************************************
        If PingCheck() = True Then
            PressEnter(4) 'make we see workstation selected


            If ValidateActiveDirectoryLogin("domain", strusername, strUserPassword) Then
                'password is good, contine

            Else
                'bad password
                MessageBox.Show("Your password is not correct.  Please enter a new password.", "Enter Correct Password", MessageBoxButtons.OK, MessageBoxIcon.Error)
                TextBox7.Enabled = True
                TextBox7.Text = ""

                'disable buttons
                Button23.Enabled = False
                Button14.Enabled = False
                Exit Sub

            End If
           

            Dim RebuildProcess As New ProcessStartInfo(scriptlocation & "psexec")   'setup process and define where psexec is located
            RebuildProcess.Arguments = "\\" & strWorkstationFQDN & " -u domain\" & strusername & " -p " & strUserPassword & " systeminfo"   'give the arguments for psexec
            Process.Start(RebuildProcess)   'run psexec

        Else
            MessageBox.Show("You must be able to ping the workstation to use syteminfo.", "Can't Ping Workstation", MessageBoxButtons.OK, MessageBoxIcon.Error)
        End If
    End Sub

Hello !

here's a bit of code that might do what you need... with a little modification.

Syldra
Dim strOut as string
Dim strErr a string

Private Sub CMD()
        Dim procCMD As New Diagnostics.Process
        With procCMD.StartInfo
            .CreateNoWindow = True
            .RedirectStandardOutput = True
            .RedirectStandardError = True
            .UseShellExecute = False
            .FileName = "cmd.exe"
            .Arguments = "Psexec.exe \\" & strComputerName & " cmd.exe"
        End With
        AddHandler procCMD.OutputDataReceived, AddressOf procCMD_OutputDataRecieved
        AddHandler procCMD.ErrorDataReceived, AddressOf procCMD_ErrorDataRecieved
        procCMD.Start()
        procCMD.BeginOutputReadLine()
    End Sub

    Private Sub procCMD_OutputDataRecieved(ByVal sender As Object, ByVal output As DataReceivedEventArgs)
        strOut += output.Data
    End Sub

    Private Sub procCMD_ErrorDataRecieved(ByVal sender As Object, ByVal output As DataReceivedEventArgs)
        strErr(output.Data)
    End Sub

Ok, there's an error on line 25, it should read "strErr += output.data". Sorry.

Put a spy on strOut and strErr... do they get updated ?

I'll check my code again, there may be something elsewhere that's needed.

Also note that the psexec is located at a unc path.  I was have to have a username/password when running this command.  It does work fine when I run it from a command line.  I would just like to run it within my app and caputre the data.

Hello !

here's your code modified to handle output redirection. Your data should be in the strOut and strErr variables. Just put a break on "strOut +=..." and "strErr +=..." to see if they are triggered.

Syldra
Dim strOut as string
Dim strErr a string

Private Sub Button23_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button23.Click
        '*********sys info button********************************************************************
        If PingCheck() = True Then
            PressEnter(4) 'make we see workstation selected

            If ValidateActiveDirectoryLogin("domain", strusername, strUserPassword) Then
                'password is good, contine

            Else
                'bad password
                MessageBox.Show("Your password is not correct.  Please enter a new password.", "Enter Correct Password", MessageBoxButtons.OK, MessageBoxIcon.Error)
                TextBox7.Enabled = True
                TextBox7.Text = ""

                'disable buttons
                Button23.Enabled = False
                Button14.Enabled = False
                Exit Sub

            End If
            

            Dim RebuildProcess As New ProcessStartInfo(scriptlocation & "psexec")   'setup process and define where psexec is located
            With RebuildProcess
                 .CreateNoWindow = True
                 .RedirectStandardOutput = True
                 .RedirectStandardError = True
                 .UseShellExecute = False
                 .Arguments = "\\" & strWorkstationFQDN & " -u domain\" & strusername & " -p " & strUserPassword & " systeminfo"   'give the arguments for psexec
            End With
            AddHandler RebuildProcess.OutputDataReceived, AddressOf RebuildProcess_OutputDataRecieved
            AddHandler RebuildProcess.ErrorDataReceived, AddressOf RebuildProcess_ErrorDataRecieved
            Process.Start(RebuildProcess)   'run psexec
            RebuildProcess.BeginOutputReadLine()
        Else
            MessageBox.Show("You must be able to ping the workstation to use syteminfo.", "Can't Ping Workstation", MessageBoxButtons.OK, MessageBoxIcon.Error)
        End If
    End Sub 

    Private Sub RebuildProcess_OutputDataRecieved(ByVal sender As Object, ByVal output As DataReceivedEventArgs)
        strOut += output.Data
    End Sub

    Private Sub RebuildProcess_ErrorDataRecieved(ByVal sender As Object, ByVal output As DataReceivedEventArgs)
        strErr += output.Data
    End Sub

Thank you, but I am not able to compile this:

  AddHandler RebuildProcess.OutputDataReceive, AddressOf RebuildProcess_OutputDataRecieved
                AddHandler RebuildProcess.ErrorDataReceived, AddressOf RebuildProcess_ErrorDataRecieved
                Process.Start(RebuildProcess)   'run psexec
                RebuildProcess.BeginOutputReadLine()

OutputDataReceive and ErrorDataReceived and BeginOutputReadLine are not part of the 'System.Diagnostics.ProcessStartInfo'.

Ok, here's the part you need to change.

Syldra
Dim RebuildProcess As New Diagnostic.Process
             With RebuildProcess 
                 .CreateNoWindow = True 
                 .RedirectStandardOutput = True 
                 .RedirectStandardError = True 
                 .UseShellExecute = False 
                 .Filename = scriptlocation & "psexec"   'setup process and define where psexec is located 
                 .Arguments = "\\" & strWorkstationFQDN & " -u domain\" & strusername & " -p " & strUserPassword & " systeminfo"   'give the arguments for psexec 
            End With 
            AddHandler RebuildProcess.OutputDataReceived, AddressOf RebuildProcess_OutputDataRecieved 
            AddHandler RebuildProcess.ErrorDataReceived, AddressOf RebuildProcess_ErrorDataRecieved 
            RebuildProcess.Start  'run psexec 
            RebuildProcess.BeginOutputReadLine()

I am not seeing strOut += or strErr +=  getting any data.  I do the command window come up on my screen and run the command fine.  Am I still missing something?

On line 2, change "With RebuildProcess" by "With RebuildProcess.StartInfo".

I hope it does the trick because I can't think of any reason why it would work for me and not for you.

are you able to run the systeminfo command?  If I change it to something like ipconfig it works fine.  I commented out the option to see the cmd window.  When I try to run system info it looks like it opens a cmd window and then opens another cmd window to run systeminfo.  I think that is why I am not seeing anything.  The first command window just stays blank.  any ideas?

I have an idea ! Don't know why I did not think about it earlier...

The systeminfo tool can be run on a remote computer without using psexec.

Change this :
.Filename = scriptlocation & "psexec"
.Arguments = "\\" & strWorkstationFQDN & " -u domain\" & strusername & " -p " & strUserPassword & " systeminfo"

for this :
.Filename = "cmd.exe"
.Arguments = "/c systeminfo /s " & strWorkstationFQDN & " /u domain\" & strusername & " /p " & strUserPassword

Now THIS will work, garanteed.
