C#显示隐藏窗口
我正在为excel开发一个外接程序。在某种程度上，我可以接收异步事件。如果在这些事件中隐藏，我需要能够显示Excel窗口 我能够存储C#显示隐藏窗口,c#,windows,hwnd,C#,Windows,Hwnd,我正在为excel开发一个外接程序。在某种程度上，我可以接收异步事件。如果在这些事件中隐藏，我需要能够显示Excel窗口 我能够存储Hwnd属性，我认为它必须是一个不可变的int/reference来标识我的Excel窗口 有人能详细说明一下这个Hwnd吗？并解释如何使用C#显示隐藏窗口 提前感谢各位；） 更新：很快，这就是解决我问题的代码： /// <summary>Enumeration of the different ways of showing a window
