Virtual Developer Workshop: Containerized Development with Docker
This article was contributed by Elmue.
Environment: Windows NT/2000/XP
This program demonstrates the use of these API commands:
Try this demo with an Administrator Account and a normal User or Guest Account! This program logs all commands it receives and executes into the logfile C:\DemoService.txt.
This program is used in two modes:
- Service.exe (without parameters) runs the program with the GUI (see screenshot)
- Service.exe /Service runs it as a Service (Windows calls Service.exe with the "/Service" parameter if the already installed Service is started)
In a Service, it is not possible to set a normal Timer (SetTimer()) because the service does not own a window and can't receive Window Messages.
For demonstration, I set a waitable timer that writes every five seconds to the log file, even when no user is logged on.
