Well with one exception, with that basic example the user’s environmental variables will not be set – so for example if from that newly launched command prompt process you type “Echo %USERNAME%” then it will show that the %USERNAME% variable is currently set to the local system account. As soon as CreateProcessAsUser is called, the process will be started and will appear on the user’s screen and act just like any other program. Obviously this example launches command prompt but you can replace C:\Windows\System32\cmd.exe with whatever application you want to launch. If Not UserTokenHandle = IntPtr.Zero Then WindowsApi.CreateProcessAsUser(UserTokenHandle, "C:\Windows\System32\cmd.exe", IntPtr.Zero, IntPtr.Zero, IntPtr.Zero, False, 0, IntPtr.Zero, Nothing, StartInfo, ProcInfo) StartInfo.cb = CUInt(Runtime.InteropServices. PROCESS_INFORMATIONĭim StartInfo As New WindowsApi. WindowsApi.WTSQueryUserToken( WindowsApi.WTSGetActiveConsoleSessionId, UserTokenHandle)ĭim ProcInfo As New WindowsApi. Here is the most basic example I could come up with (needs error handling etc):ĭim UserTokenHandle As IntPtr = IntPtr.Zero Oh and you don’t need to mark your service as an Interactive service and the user will not get switched to the ‘services’ desktop when they try to interact with the newly launched process. I’ve seen plenty of other different ways of doing this, some unnecessarily complex, but this method I am going to demonstrate seems to be by far the most simple and elegant. I’m using it as part of an installation package for a program that we deploy via SCCM (which therefore gets run from the SCCM Agent service) to run a one off job that needs to be executed as the currently logged on user to avoid them needing to log out and back on before the newly deployed application will work correctly (and no its not just HKCU registry edits or anything like that which could be done in an easier way). I think of this as a quick and dirty way of doing it if you can’t do it a more ‘proper’ way. The only reason for posting this method is because in some scenarios that ideal method is not always possible or not warranted. Turns out it is actually very easy…įirstly, I do not really recommend this method because ideally you should have a process running in the user’s session already that communicates with your service via Named Pipes, TCP/IP, or whatever – this process can receive a command from your service and launch/do whatever you want and it will already be running in the user’s session and security context.

NET, see my book Visual Basic 2005 Programmer's Reference.Launching a process that the currently logged on user can see on their desktop session (and interact with) from a Windows service is a popular topic – and there are a wide variety of answers out there when someone asks how to do this, some people say it is not even possible on Windows Vista or Windows 7.

You should be able to use similar code in earlier versions of VB. ' Make the process and set its start information.ĭim std_out As StreamReader = proc.StandardOutput()ĭim std_err As StreamReader = proc.StandardError() Private Sub btnRun_Click(.) Handles btnRun.Clickĭim start_info As New ProcessStartInfo(txtProgram.Text) Then start the process.Īttach StreamReaders to the Process's StandardOutput and StandardError streams, read their contents, and display the results. Next create a Process object and set its StartInfo property to the ProcessStartInfo object. Use its properties to indicate that the DOS program should not use ShellExecute, should not create a separate window, and should redirect standard output and standard error.
