如何隐藏/显示任务栏？ [英] How can I Hide/Show Taskbar?

问题描述

大家好，

Hi everyone,

private static void SetVisibility(bool show)
        {
            // get taskbar window
            IntPtr taskBarWnd = FindWindow("Shell_TrayWnd", null);

            // try it the WinXP way first...
            IntPtr startWnd = FindWindowEx(taskBarWnd, IntPtr.Zero, "Button", "Start");
            if (startWnd == IntPtr.Zero)
            {
                // ok, let's try the Vista easy way...
                startWnd = FindWindow("Button", null);

                if (startWnd == IntPtr.Zero)
                {
                    // no chance, we need to to it the hard way...
                    startWnd = GetVistaStartMenuWnd(taskBarWnd);
                }
            }

            ShowWindow(taskBarWnd, show ? SW_SHOW : SW_HIDE);
            ShowWindow(startWnd, show ? SW_SHOW : SW_HIDE);
        }

使用该功能，我可以隐藏任务栏，但它不再显示。

对于隐藏任务栏我正在使用Form DeActive Event，而对于Show Taskbar我正在使用Form_Closing Event。但它不起作用..



有什么问题？我该如何解决？



感谢您的回答，祝您有个美好的一天......

With that function, I can hide Taskbar, but it isn't showing again.
For Hide Taskbar I'm using Form DeActive Event, and for Show Taskbar I'm using Form_Closing Event. But it is not work..

What is the problem? How can I solve?

Thanks for answers, have a good day...

推荐答案

Long我曾经使用过.net Forms，但是我记得有一个内置的选项可以在任务栏中显示/隐藏windown，例如： this.ShowInTaskbar = false;



因为你已经进入WinAPI了。如果需要，我强烈建议加倍思考和研究。如果你仍然认为winapi是最好的方法，请阅读： https://msdn.microsoft.com/en-us/library/windows/desktop/ff700543(v=vs.85).aspx [ ^ ]你想这样做应该可以解决问题：

Long time I used .net Forms, but as I remember there was an built in option to show/hide windown in taskbar somethink like: this.ShowInTaskbar = false;

As you already got into WinAPI for doing that. I strongly suggest to double think and research if it's needed. If you still think winapi is the best approach, read this: https://msdn.microsoft.com/en-us/library/windows/desktop/ff700543(v=vs.85).aspx[^] you somethink like this should do the trick:

SetWindowLong(handle, GWL_EXSTYLE, GetWindowLong(handle, GWL_EXSTYLE) | WS_EX_APPWINDOW);

SetWindowLong(handle, GWL_EXSTYLE, GetWindowLong(handle, GWL_EXSTYLE) & ~WS_EX_APPWINDOW);

想法是获取当前窗口样式并添加或删除所需的标志（还可以阅读有关按位操作以及添加/删除标志的方式）。

The idea is to get the current window style and add or remove flags you want (also read about bitwise operations and how adding/removing flags works).
