I want to open a balloon tooltip using windows service. I can do it in Windows Forms. Is it possible using windows service ?
I have implemented this service before and used a named pipe. Basically you create two applications.
The windows service pushes messages towards the clients that are connected, could be multiple users on the systems running the winforms app.
The winforms app listens to messages on the pipe. Once the message comes in you can make the balloon pop up.
Here is a cool test project: https://www.codeproject.com/Tips/492231/Csharp-Async-Named-Pipes
Happy coding!
