Redirect output of shell commands to file - shell

I am running following command from Command Prompt
dir > c:\log.txt 2>&1
The out is directed to c:\log.txt file successfully.
Then, running the same command using CreateProcessA as below and nothing happens
Public Function ExecCmd(cmdline$)
Dim proc As PROCESS_INFORMATION
Dim start As STARTUPINFO
Dim ret As Long
start.cb = Len(start)
start.dwFlags = 1
start.wShowWindow = 1
ret& = CreateProcessA(vbNullString, cmdline$, 0&, 0&, 1&, NORMAL_PRIORITY_CLASS, 0&, vbNullString, start, proc)
ret = WaitForSingleObject(proc.hProcess, INFINITE)
Call GetExitCodeProcess(proc.hProcess, ret&)
Call CloseHandle(proc.hThread)
Call CloseHandle(proc.hProcess)
ExecCmd = ret&
End Function
Here cmdline$ is passed as dir > c:\log.txt 2>&1
I have tried Batch file - How to redirect output from exe after it has terminated? and Display & Redirect Output
Please suggest what is wrong here

Why don't you use the shell function? Here is an example of how to redirect the output:
Option Explicit
Private Sub Form_Load()
ExecCmd "dir >c:\log.txt 2>&1"
End Sub
Private Sub ExecCmd(cmdline As String)
Shell "cmd /c " & cmdline, vbHide
End Sub

i need to add list to this command according to https://sevenzip.osdn.jp/chm/cmdline/commands/list.htm so that file names gets displayed in output data
The following Microsoft article describes two methods that read the output of a command: WSH: Running Programs
The simplest uses the StdOut property of the WshExec object:
Set objShell = WScript.CreateObject("WScript.Shell")
Set objExecObject = objShell.Exec("cmd /c ping -n 3 -w 1000 157.59.0.1")
Do While Not objExecObject.StdOut.AtEndOfStream
strText = objExecObject.StdOut.ReadLine()
If Instr(strText, "Reply") > 0 Then
Wscript.Echo "Reply received."
Exit Do
End If
Loop
You can replace the ping command here with your 7z command and read StdOut to see what your command returned.
Since you are doing this in VB6, you can add a reference (Projects menu > References) to Windows Script Host Object Model library and instantiate the objects with the proper types directly:
Dim objShell As New WshShell
Dim objExecObject As WshExec
Dim strText As String
Set objExecObject = objShell.Exec("cmd /c ping -n 3 -w 1000 127.0.0.1")
Do While Not objExecObject.StdOut.AtEndOfStream
strText = objExecObject.StdOut.ReadLine()
If InStr(strText, "Reply") > 0 Then
Debug.Print "Reply received: " & strText
Exit Do
End If
Loop
With this approach you don't need the DOSCommand.cls, you can simply use the WshShell object for all your operations.
Your Command22_Click would look like this:
Private Sub Command22_Click()
On Error GoTo errore
Dim objShell As New WshShell
Dim objExecObject As WshExec
Dim strText As String
Set objExecObject = objShell.Exec(text6.Text)
Do While Not objExecObject.StdOut.AtEndOfStream
strText = objExecObject.StdOut.ReadLine()
' Parse the text your 7z command returned here
If InStr(strText, "41_gfx7.rom") > 0 Then
Text1.Text = Text1.Text & strText & vbCrLf
Exit Do
End If
Loop
Exit Sub
errore:
MsgBox (Err.Description & " - " & Err.Source & " - " & CStr(Err.Number))

Read VBScript window for answer and execute into Batch

exit
I have (above) batch file that runs CURL and writes output into a txt file.
And this (below) vbs file reads the content and shows message.
As you can see there is a start command in my batch file.
If I click Yes in vbs window I want to execute that start command.
If I click No in vbs window I want to go to exit.

End Select

It it possible to do that? If so how?

VBS Run cmd.exe output to a variable; not text file

This is what I have so far. It works; outputing the folder path to temp to a text file.
What I really want, is to output the data to a variable. Every example I see online, show how to do this using something like:
set objScriptExec = wshShell.Exec (strCommand)
followed by
strresult = LCase(objScriptExec.StdOut.ReadAll. // code
I want this to run with Run, not Exec, because I want the command prompt windows to be hidden as I will performing many commands with the code below. How can I capture that output to a variable?
Set wsShell = CreateObject("WScript.Shell")
strCommand = "cmd /c echo %temp% > %temp%\test.txt"
wsShell.Run strcommand,0,True
This may be done with the Windows Script Host Exec command. StdOut, StdIn, and StdErr may all be accessed, and ERRORLEVEL is available when the command completes.
Dim strMessage, strScript, strStdErr, strStdOut
Dim oExec, oWshShell, intErrorLevel
Dim ComSpec
Set oWshShell = CreateObject("WScript.Shell")
ComSpec = oWshShell.ExpandEnvironmentStrings("%comspec%")
intErrorLevel = 0
strScript = ComSpec & " /C echo %temp%"
On Error Resume Next
Set oExec = oWshShell.Exec (strScript)
If (Err.Number <> 0) Then
strMessage = "Error: " & Err.Message
intErrorLevel = 1
Else
Do While oExec.Status = 0
Do While Not oExec.StdOut.AtEndOfStream
strStdOut = strStdOut & oExec.StdOut.ReadLine & vbCrLf
Loop
Do While Not oExec.StdErr.AtEndOfStream
strStdErr = strStdErr & oExec.StdErr.ReadLine & vbCrLf
Loop
WScript.Sleep 0
Loop
intErrorLevel = oExec.ExitCode
strMessage = strStdOut & strStdErr & CStr(intErrorLevel)
End If
WScript.Echo (strMessage)
NOTE: Replacing "ReadLine" above with "Read(1)" accomplishes the same thing, but adds an ability to process characters rather than whole lines.
Of course Wscript.Shell would be a lot easier, but, since you want more fine grain control of your session, consider using Win32_Process. Usually, one uses this to control the placement of a new window, but, in your case, you want it hidden, so I set startupInfo.ShowWindow = 0 which means SW_HIDE. The following declares a VBScript function called RunCmd and which will run a command in an invisible window saving the output to a text file and then return the contents of the text file to the caller. As an example, I invoke RunCmd with the HOSTNAME command:
Function RunCmd(strCmd)
Dim wmiService
Set wmiService = GetObject("winmgmts:\\.\root\cimv2")
Dim startupInfo
Set startupInfo = wmiService.Get("Win32_ProcessStartup")
Dim fso
Set fso = CreateObject("Scripting.FileSystemObject")
Dim cwd
cwd = fso.GetAbsolutePathname(".")
startupInfo.SpawnInstance_
startupInfo.ShowWindow = 0
' startupInfo.X = 50
' startupInfo.y = 50
' startupInfo.XSize = 150
' startupInfo.YSize = 50
' startupInfo.Title = "Hello"
' startupInfo.XCountChars = 36
' startupInfo.YCountChars = 1
Dim objNewProcess
Set objNewProcess = wmiService.Get("Win32_Process")
Dim intPID
Dim errRtn
errRtn = objNewProcess.Create("cmd.exe /c """ & strCmd & """ > out.txt", cwd, startupInfo, intPID)
Dim f
Set f = fso.OpenTextFile("out.txt", 1)
RunCmd = f.ReadAll
f.Close
End Function
MsgBox RunCmd("HOSTNAME")

Visual Basic for Applications (VBA) Shell

I'd like to invoke a script on my linux server using VBA in Excel. To do this, I'm using a local copy of Putty that's in the path.
I've successfully written a single command to create a putty session and log in to the server, I'm just unsure how to pass another command after this has been opened in the shell.
Any Ideas?
The below subroutine works, but causes a problem when the second command is attempted.
Cheers

Shell process' standard output reading in Visual Basic 6

First, let me say that I'm not a Visual Basic 6 expert...
My need is to:
launch from a VB6 client code an exeternal .exe file
wait for the process to finish and - during its execution - read the messages coming from its standard output "on the fly" (so that I can print it on a text-filed widget or similars).
I'm wondering if it is even possible to do that in VB6...after a long search on the Internet I didn't come up with anything. Found a lot of examples of how to use the Shell function, but it seems to force me to read the stdout all at once when the process' execution is over, but I want to poll the process for "fresh" messages as they become available.
Any code snippets/suggestions/references are really appreciated.
Thanks in advance!
Use CreatePipe() to create an anonymous pipe that you can pass to CreateProcess().
You can then read from this pipe as required (either using polling or overlapped/async I/O.
This should give you enough info to find a good example.
You can always use Exec method of WshShell to do the job.
I prefer to use a home-grown API based solution cExec.cls much simpler than Bob Riemersma's user control (but not as versatile).
You can also create a batch file that has all the commands that you need to run, and then from VB6 call the batch file by executing
Shell "C:\YourPath\BatchFileName.bat > OutputFileName.txt" 'Overwrites OutputFilename.txt everytime
once you execute that, then open OutputFileName.txt and you will find all of the messages and output that was generated during the batch process. You can then read it in VB6 in a simple open "filename" for input as #1
You should also notice that if you use double GreaterThan symbols, the the output file will not be overwritten every time the batch runs. Instead, it will get appended with the new lines of output.
Shell "C:\YourPath\BatchFileName.bat >> OutputFileName.txt" 'This will append to OutputFileName.txt
