Windows如何强制“最小化" Windows操作系统?桌面快捷方式打开状态? [英] How does Windows force "minimized" state from a desktop shortcut?

问题描述

我有一个旨在最小化系统托盘的应用程序.那里没有问题.

I have an application that is designed to minimize to the system tray. No issues there.

我遇到的问题是，当我设置可执行文件的桌面快捷方式并启动它时，我无法确定Windows正在做什么以强制最小化状态，例如:

The problem I am having is that I cannot determine what Windows is doing to force the minimized state when I set up a desktop shortcut to that executable and launch it, such as:

我将一些调试输出放入窗体的构造函数中，并通过快捷方式启动.我没有命令行参数，而WindowState的检查结果为Normal.然而，该应用程序开始最小化到任务栏.

I put some debug outputs in the form's constructor and launched via the shortcut. I get no command line arguments and a check of WindowState yields Normal. Yet the app starts minimized to the taskbar.

但是，这很麻烦:我希望它开始最小化到系统托盘，就像在屏幕上显示表单并且用户将其最小化一样.当然，并非总是如此，只是在使用最小化"快捷方式时，或者在用户单击表单上的最小化"时.

However, that's the rub: I want it to start minimized to the system tray, just as it would if the form were on-screen and the user minimized it. Not all the time, just when a "minimize" shortcut is used, or when the user clicks Minimize on the form, of course.

出于好奇...我的初始测试存在缺陷，因为我签入了构造函数.将测试放在Load方法中会产生一个Minimized状态，然后我可以对此状态做出反应并调用我的代码以执行最小化托盘"操作.

for the curious...my initial testing was flawed because I checked in the constructor. Placing the test in the Load method produced a Minimized state, to which I could then react and call my code to perform the "minimize-to-tray".

推荐答案

Windows正在使用最小化主窗口的参数启动该过程.

Windows is starting the process with parameters to minimize the main window.

在C#中，您可以通过设置

In C#, you can do the same by setting WindowStyle (MSDN) at ProcessStartInfo for use in Process.Start().

在原生世界中，您将使用 CreateProcess(MSDN) API并传递

In the native world, you would use the CreateProcess (MSDN) API and pass a STARTUPINFO, setting wShowWindow to SW_MINIMIZE.

要查询窗口状态，请使用 Form.WindowState .

To query the window state, use GetWindowInfo (MSDN), look at dwStyle and check if WS_MINIMIZEis set. In C#, this should be in Form.WindowState.
