问题描述
我工作的应用程序（C＃2.0）。我在它执行单一实例。一切安好。如果我再次运行应用程序，它显示消息框，说：实例已在运行。
I am working on the application (C# 2.0). I have implemented single instance in it. Everything is fine.If i run the application again, it shows messagebox saying "instance is already running".
其实我并不想通过显示消息框，该消息。
Actually i don't want to show the message through messagebox.
我想显示使用已经运行实例的气球提示该信息（它有通知系统托盘图标）。
I want to show this message using Balloon tip of already running instance (it has notify icon in system tray).
我怎样才能做到这一点？
How can i achieve this?
在此先感谢。
推荐答案
您需要的<一个形式href="http://www.google.co.uk/search?rlz=1C1GGLS%5Fen-GBGB300GB305&sourceid=chrome&ie=UTF-8&q=c%23+interprocess+communication"相对=nofollow>进程间通信，发信号给另一个实例，它应该显示消息框。
You need a form of interprocess communication, to signal to the other instance that it should display the messagebox.
在这种情况下，你可以去比告诉现有的实例，以显示该消息一筹，而是告诉它来恢复它的主窗口（即unminimise）。
In this instance, you could go one better than telling the existing instance to display the message, and instead tell it to restore it's main window (i.e. "unminimise").
