Powershell waitforexit example

Author: Creedderign On: 30.05.2017

I'm trying to run a program from PowerShell, wait for the exit, then get access to the ExitCode, but not having much luck.

I don't want to use -Wait with Start-Process, as I need some processing to carry on in the background. Running this script will cause notepad to be started. After this is closed manually, the exit code will be printed, and it will start again, without using -wait. No ExitCode is provided when this is quit:. I need to be able to perform additional processing between starting the program and waiting for it to quit, so I can't make use of -Wait.

Any idea how I can do this and still have access to the. ExitCode property from this process? There are two things to remember here.

One is to add the -PassThru argument and two is to add the -Wait argument. You need to add the wait argument because of this defect http: Once you do this a process object is passed back and you can look at the ExitCode property of that object.

While trying out the final suggestion above, I discovered an even simpler solution. All I had to do was cache the process handle.

CarlR This is a quirk of the implementation of the. The implementation of the ExitCode property first checks if the process has exited. For some reason, the code that performs that check not only looks at the HasExited property but also verifies that the proces handle is present in the proces object and throws an exception if it is not.

PowerShell intercepts that exception and returns null. Accessing the Handle property causes the process object to retrieve the process handle and store it internally. Once the handle is stored in the process object, the ExitCode property works as expected. Or try adding this Greg Vogel 51 5. Handle after starting the process with Start-Process.
