CreateProcessAsUser or LogonUser

byka

How can I use the CreateProcessAsUser or LogonUser when staring the process:

Dim ps As New System.Diagnostics.Process
ps.StartInfo.UseShellExecute = False
ps.StartInfo.Domain = Domain
ps.StartInfo.UserName = UserName

        Dim pword As New System.Security.SecureString()
        For Each c As Char In Password
            pword.AppendChar(c)
        Next
        ps.StartInfo.Password = pword
        ps.StartInfo.LoadUserProfile = False


        'This Works:
        ps.StartInfo.WorkingDirectory = ApplicationWorkingDir
        ps.StartInfo.FileName = "cmd.exe"
      
        'Win2012 run as admin
         ps.StartInfo.Verb = "runas"
       
       
        If BatchSize = String.Empty Then
            ps.StartInfo.Arguments = "/c  bcp " + DbTable + " in " + SourceFile + " -m " + MaxErrors + " -f " & FMTFile & " -e " & ErrorFile & " -o " & LogFile & " -S " & ServerName & " -T "
        Else
            ps.StartInfo.Arguments = "/c bcp " + DbTable + " in " + SourceFile + " -m " + MaxErrors + " -f " & FMTFile & " -b" & BatchSize & " -e " & ErrorFile & " -o " & LogFile & " -S " & ServerName & " -T"
        End If

        ps.StartInfo.WindowStyle = ProcessWindowStyle.Hidden
        ps.Start()

        ps.WaitForExit()

What kind of app are you writing and where is this process being started? Is this a Windows Forms app, console app, WPF, Windows Service, ASP.NET, ... ?? Is the process being created locally, meaning on the same machine as the code you've shown or is it being created on a remote machine? ....and you STILL do not have to run CMD and do not need the "RunAs" verb line. It's nice to see you don't listen to the answers you've been given.

To quote Dave: "On top of everything else, in order for the Hidden window option to work you have to change the UseShellExecute property to True." - in which case the verb won't work. Calling BCP from .net on Windows 2012 - Visual Basic Discussion Boards - CodeProject[^]

it's a console application running on a server from a scheduler. I need to start a process as specific user with access to cmd.exe and pass userID in my process

The default task scheduler[^] contains options to run your app under another account. So, I assume you are not using that task-scheduler?

You mean that it should display a console-window where the user can execute additional commands? You don't need to start CMD just to execute an application that you would normally start using the CMD-prompt.

Maybe this explanation will help : scheduler running under user account with no permission to C: drive. Application account should have some permission to C:drive in order to access cmd.exe I need to add code ( CreateProcessAsUser or LogonUser) for application user in order to call cmd.exe

Dave Kreskowiak

OK, this is a bit better but there's still lots of detail missing. You're writing the scheduler app? Is this written as a standard console or Windows Forms application or is it a service? Does the application this scheduler is launching have to show up as a window that the user can type in? Why must you call CMD instead of just launching BCP directly?

An answer to the question would have helped too. Are you or are you not using the default task scheduler? If yes, simply define the account you want to run under in the settings.

..sounds safer to give the user the permissions he/she actually needs. The user you are impersonating prolly has some more priviliges than just "cmd.exe".

If you're using the default task scheduler, supply credentials that have appropriate permissions. If you've baked your own task scheduler, run it as a service, using credentials that have appropriate permissions. Either way, the wheel, axle, transmission, and engine have already been invented. You just need to paint the car.

You're writing the scheduler app? - Yes Is this written as a standard console or Windows Forms application or is it a service? - Consolse application Does the application this scheduler is launching have to show up as a window that the user can type in? - No Why must you call CMD instead of just launching BCP directly?- you mean call bcp.exe instead of cmd?

yes.

That's not an answer to the question. WHY do you think you must call CMD instead of just launching BCP directly?
