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").
