im trying to get the windows license status from cmd by running this code
Dim oProcess As New Process()
Dim oStartInfo As New ProcessStartInfo("cmd.exe", " /c cscript ""%windir%\system32\slmgr.vbs"" /xpr | findstr ""The machine""")
oStartInfo.CreateNoWindow = True
oStartInfo.WindowStyle = ProcessWindowStyle.Hidden
oStartInfo.UseShellExecute = False
oStartInfo.RedirectStandardOutput = True
oProcess.StartInfo = oStartInfo
oProcess.Start()
Dim sOutput As String
Using oStreamReader As System.IO.StreamReader = oProcess.StandardOutput
sOutput = oStreamReader.ReadToEnd()
End Using
TextBox4.Text = sOutput
Select Case sOutput
Case Is = "The machine is permanently activated."
TextBox4.Text = "activated"
End Select
the code is working okay but the result that appears on my textbox4 is : The machine is permanently activated. i need to take this result to case statement
Select Case sOutput
Case Is = "The machine is permanently activated."
TextBox4.Text = "activated"
all i need if i get The machine is permanently activated. status from cmd then show in textbox4 word ( activated )
It could be that the output contains a space or a line break at the end. Call Trim() on the string to remove any leading or trailing spaces and/or line breaks.
Select Case sOutput.Trim()

I'm currently writing a sub in vb.net that is supposed to create and/or erase tasks in the task scheduler that comes with windows 10. The creation part works fine, but when I try to erase the task I get this error in the visual studio console: "The process tried to write to a nonexistent pipe", and the task is (of course) still there. I've looked for a solution but can't find anything similar. Here is the code:
Private Sub SimpleButton2_Click(sender As Object, e As EventArgs) Handles sbAutoRun.Click
Dim CMDThread As New Threading.Thread(AddressOf CMDAutomate)
CMDThread.Start()
End Sub
Private Sub CMDAutomate()
Dim myprocess As New Process
Dim StartInfo As New System.Diagnostics.ProcessStartInfo
Dim sTime As String = teAutoRun.Time.ToString("HH:mm")
Dim sCmdCommand As String = "SCHTASKS /CREATE /SC DAILY /TN ""MyTasks\task"" /TR ""'" & My.Application.Info.DirectoryPath & "\program.exe' Auto"" /ST " & sTime & " /RL HIGHEST"
Dim sCmdCommand2 As String = "SCHTASKS /DELETE /TN ""MyTasks\task"""
My.Settings.AutoRun = ceAutoRun.Checked
StartInfo.FileName = "cmd" 'starts cmd window
StartInfo.RedirectStandardInput = True
StartInfo.RedirectStandardOutput = True
StartInfo.CreateNoWindow = True '<---- if you want to not create a window
StartInfo.UseShellExecute = False 'required to redirect
myprocess.StartInfo = StartInfo
myprocess.Start()
Dim SR As System.IO.StreamReader = myprocess.StandardOutput
Dim SW As System.IO.StreamWriter = myprocess.StandardInput
If My.Settings.AutoRun And Not My.Settings.AutoRunExists Then
SW.WriteLine(sCmdCommand)
My.Settings.AutoRunExists = True
Console.WriteLine(sCmdCommand)
ElseIf My.Settings.AutoRun And My.Settings.AutoRunExists Then
SW.WriteLine(sCmdCommand2)
SW.WriteLine("y")
SW.WriteLine(sCmdCommand)
Else
SW.WriteLine(sCmdCommand2)
SW.WriteLine("y")
My.Settings.AutoRunExists = False
Console.WriteLine(sCmdCommand2)
End If
SW.WriteLine("exit") 'exits command prompt window
SW.Close()
SR.Close()
My.Settings.Save()
End Sub
Thanks..
Ps: The commands work fine when entered by hand in the cmd.
Update: Changed this
sCmdCommand2 As String = "SCHTASKS /DELETE /TN ""MyTasks\task"""
SW.WriteLine(sCmdCommand2)
SW.WriteLine("y")
and wrote it like this
sCmdCommand2 As String = "SCHTASKS /DELETE /TN ""MyTasks\task"" /F"
SW.WriteLine(sCmdCommand2)
Now it works fine.
I'm trying to hide cmd windows with vb.net without success.
Dim oProcess As New Process()
Dim oStartInfo As New ProcessStartInfo("cmd.exe", " /c cscript ""%windir%\system32\slmgr.vbs"" /xpr | findstr ""The machine""")
oStartInfo.WindowStyle = ProcessWindowStyle.Minimized
oStartInfo.WindowStyle = ProcessWindowStyle.Hidden
oStartInfo.UseShellExecute = False
oStartInfo.RedirectStandardOutput = True
oProcess.StartInfo = oStartInfo
oProcess.Start()
Dim sOutput As String
Using oStreamReader As System.IO.StreamReader = oProcess.StandardOutput
sOutput = oStreamReader.ReadToEnd()
End Using
TextBox4.Text = sOutput
any help please what is the mistake in my code ?
You must set the CreateNoWindow property as well.
oStartInfo.CreateNoWindow = True
Also, this is just redundant:
oStartInfo.WindowStyle = ProcessWindowStyle.Minimized '<-- Remove this line.
oStartInfo.WindowStyle = ProcessWindowStyle.Hidden
Setting WindowStyle to minimized won't affect anything since you change it to Hidden right after. When you use the = operator you replace a variable's or property's current value with a new one.
I need to know, if you could help me, how to insert commands in vb then they run in cmd and i get the output.
I need to do "net localgroup Administradores a58465 /add" and get the error message if there is one.
Solution: `Dim myProcess As Process = New Process
Dim s As String
myProcess.StartInfo.FileName = "c:\windows\system32\cmd.exe"
myProcess.StartInfo.UseShellExecute = False
myProcess.StartInfo.CreateNoWindow = True
myProcess.StartInfo.RedirectStandardInput = True
myProcess.StartInfo.RedirectStandardOutput = True
myProcess.StartInfo.RedirectStandardError = True
myProcess.Start()
Dim sIn As System.IO.StreamWriter = myProcess.StandardInput
Dim sOut As System.IO.StreamReader = myProcess.StandardOutput
Dim sErr As System.IO.StreamReader = myProcess.StandardError
'sIn.AutoFlush = True
sIn.Write("cls" & System.Environment.NewLine)
sIn.Write("net user" & System.Environment.NewLine)
sIn.Write("exit" & System.Environment.NewLine)
s = sOut.ReadToEnd()
If Not myProcess.HasExited Then
myProcess.Kill()
End If
LB1.Text = s
LB1.Visible = True
sIn.Close()
sOut.Close()
sErr.Close()
myProcess.Close()`
Check out Process.Start. http://msdn.microsoft.com/en-us/library/0w4h05yb(v=vs.110).aspx
Also look for the ProcessStartInfo class, which will give you options on how to kick off an external process.
Console input and output can be made available to your program through ProcessStartInfo.
I'm working on a Project by VB.net and i'm using CMD to excute commands i want to Know how to copy the Results of the CMD into a textbox on my Main Form
Take a look at the accepted answer here: Get the output of a shell Command in VB.net. That is probably what you need.
Also, here is a version of the code that puts the result into the textbox:
Dim oProcess As New Process()
Dim oStartInfo As New ProcessStartInfo("ApplicationName.exe", "arguments")
oStartInfo.UseShellExecute = False
oStartInfo.RedirectStandardOutput = True
oProcess.StartInfo = oStartInfo
oProcess.Start()
Dim sOutput As String
Using oStreamReader As System.IO.StreamReader = oProcess.StandardOutput
sOutput = oStreamReader.ReadToEnd()
End Using
txtOutput.Text = sOutput 'txtOutput being the output textbox.
I hope this helps.
Dim proc As New Process
proc.StartInfo.FileName = "C:\ipconfig.bat"
proc.StartInfo.UseShellExecute = False
proc.StartInfo.RedirectStandardOutput = True
proc.Start()
proc.WaitForExit()
Dim output() As String = proc.StandardOutput.ReadToEnd.Split(CChar(vbLf))
For Each ln As String In output
RichTextBox1.AppendText(ln & vbNewLine)
lstScan.Items.Add(ln & vbNewLine)
Next
'Created a file in batch with 2 lines as shown below:
echo off
ipconfig
' save this file as ipconfig.bat or whatever name u want.
' if you didn't want that you could use any command on there like this:
echo off
dir/s
or
echo off
cd\
dir/s
pause
I have a Process.Start command that I would like to see the output of, but the new window is opening and closing too quickly for me to see anything. Here is the code I have so far that I'm working with:
System.Diagnostics.Process.Start(Environment.GetEnvironmentVariable("VS110COMNTOOLS") & "..\Ide\MSTEST.EXE", "/Testsettings: """ & rwSettings & "" & " /Testcontainer: """ & rwContainer & "" & " /Resultsfile: """ & rwResults & "")
Unfortunately as I try to debug this if I allow this to run it flashes up the window but doesn't let me see what the error is, or if it's running successfully at all. I'm using VS2012 so I might just not be looking at the right view when I'm debugging.
Here is some code taen out of the middle of some logic, so it is not standalone. You can use ProcessStartInfo() and Process() to have more control:
Dim start_info As New ProcessStartInfo("sqlcmd", cmd)
start_info.UseShellExecute = False
start_info.CreateNoWindow = True
start_info.RedirectStandardOutput = True
start_info.RedirectStandardError = True
' Make the process and set its start information.
Dim proc As New Process()
proc.StartInfo = start_info
Dim dt As Date = Now()
' Start the process.
proc.Start()
' Attach to stdout and stderr.
Dim std_out As StreamReader = proc.StandardOutput() ' will not continue until process stops
Dim std_err As StreamReader = proc.StandardError()
' Retrive the results.
Dim sOut As String = std_out.ReadToEnd()
Dim sErr As String = std_err.ReadToEnd()
