achselschweisz / CreateProcessAsUser

Creates a process in a different Windows session

CreateProcessAsUser

This uses the Win32 apis to:

1. Find the currently active user session
2. Spawn a new process in that session

This allows a process running in a different session (such as a windows service) to start a process with a graphical user interface that the user must see.

Note that the process must have the appropriate (admin) privileges for this to work correctly.

Usage

using murrayju.ProcessExtensions;
// ...
ProcessExtensions.StartProcessAsCurrentUser("calc.exe");

Parameters

The second argument is used to pass the command line arguments as a string. Depending on the target application, argv[0] might be expected to be the executable name, or it might be the first parameter. See this stack overflow answer for details. When in doubt, try it both ways.
