问题描述

在 Vista 和 Windows 7 上隐藏任务栏时，开始按钮(也称为 Start Orb)不会被隐藏.我一直在寻找解决方案，我找到了一个，但它似乎比必要的复杂.这篇 CodeProject 文章 描述了(并包含代码)您枚举所有子项的解决方案包含开始菜单的进程中所有线程的窗口.

When hiding the Task Bar on Vista and Windows 7 the Start Button (also known as the Start Orb) doesn't get hidden. I've been looking for a solution to this and I've found one but it seems more complex than necessary. This CodeProject article describes (and contains code for) a solution where you enumerate all child windows of all threads in the process that contains the start menu.

有没有人找到更简单的解决方案?

Has anyone found a simpler solution?

仅供参考.隐藏任务栏(不隐藏球体)的代码如下.首先进行必要的 Win32 导入和声明.

Just for reference. The code for hiding the Task Bar (without hiding the Orb) is as follows. First do the necessary Win32 imports and declarations.

[DllImport("user32.dll")]
private static extern IntPtr FindWindow(string className, string windowText);

[DllImport("user32.dll")]
private static extern int ShowWindow(IntPtr hwnd, int command);


private const int SW_HIDE = 0;
private const int SW_SHOW = 1;

然后，在某个方法中，使用正确的参数调用它们

Then, in a method somewhere, call them with the right arguments

IntPtr hwndTaskBar = FindWindow("Shell_TrayWnd", "");
ShowWindow(this.hwndTaskBar, SW_HIDE);

推荐答案

我能够组合出一个不需要所有线程枚举的解决方案.以下是相关部分.

I was able to put together a solution that didn't require all the thread enumeration. Here are the relevant parts.

如果你声明 FindWindowEx 如下

[DllImport("user32.dll")]
private static extern IntPtr FindWindowEx(
       IntPtr parentHwnd,
       IntPtr childAfterHwnd,
       IntPtr className,
       string windowText);

然后您可以像这样访问 Start Orb 的窗口句柄:

You can then access the window handle for the Start Orb like this:

IntPtr hwndOrb = FindWindowEx(IntPtr.Zero, IntPtr.Zero, (IntPtr)0xC017, null);

并像这样禁用 Start Orb:

and disable the Start Orb like this:

ShowWindow(hwndOrb, SW_HIDE);

这个方法的关键是我们使用 IntPtr 类型作为 className 变量，而不是 FindWindowEx 函数中的字符串.这允许我们使用这个函数的一部分，它采用 ATOM 类型而不是 string.我能够从这篇文章中看出要使用的特定 ATOM 位于 0xC017 处:隐藏 Vista Start Orb

The key to this method is that we use the IntPtr type for the className variable instead of a string in the FindWindowEx function. This allows us to use the portion of this function that takes an ATOM type rather than a string. I was able to discern that the particular ATOM to use is at 0xC017 from this post: Hide Vista Start Orb

希望这个简化的版本可以帮助一些人.

Hope this simplified version helps some people.

更新:我创建了这个新的代码项目页面来记录这个过程.

UPDATE: I created this new Code Project Page to document this process.
