Displaying a window on a login screen using C # in Windows XP

Question

I am trying to create a service with C # that starts a process that can appear on the login screen in Windows XP.

I found code that does this in C ++. C ++ code is for a service that creates another process with the STARTUPINFO.lpDesktop parameter set to "WinSta0 \ WinLogon". The created process is then displayed on the Windows login screen. It seems I can’t find a way to specify the "desktop" of the new process in C # using the System.Diagnostic.Process class.

Does anyone know how to do this using C #?

Answer 1

The solution was to call the C ++ Win32 API CreateProcess function from kernel32.dll from C # code. This site really helped in getting the right function signature for C #:

I think you will have to write it in C ++, compile it into a DLL, and then call the DLL from your managed code.
