如何防止我的应用程序的多个实例 [英] How to prevent multiple instances of my application

问题描述

我在 Visual Basic 中发现了一个错误.在实践中，我的申请完成后，点击正常启动的可执行文件，但是如果我再次点击可执行文件(exe)，莫名其妙地打开了第二个窗口，让两个进程不必要地启动.我想知道是否有办法在某些设置中启动应用程序一次并且仅当您已经启动并且用户再次单击它时，控件而不是启动.你能做到吗?

I discovered a bug in visual basic. In practice, after completing my application, clicking on the executable file that starts normally, but if I click again on the executable file (exe), inexplicably opens a second window, getting two processes started unnecessarily. I was wondering if there was a way, maybe in some settings, to start the application once and only if you have already started and the user clicks on it again, the controls and not the start. You can do this?
