如何切换/切换Windows XP从“显示”到“自动隐藏”(反之亦然)？

基本上，我想做一个简单的切换程序（将Map到一些键盘快捷键），如果在正常模式下，将屏幕设置为自动隐藏模式（反之，如果在自动隐藏模式下，将屏幕设置为正常显示模式）。
你知道如何在C#中实现它吗？（或者Win32 C++，但任何实际上可以做到这一点的东西都很好。
谢谢，希望我说得够清楚了.

我真的不想要任何全屏应用程序，将重叠的屏幕，只有无窗口的程序，切换显示模式和退出。我从自动隐藏切换到正常视图定期，并希望简化它。（使用Win7。）

编辑。例如

  1. #include <windows.h>
  3. int CALLBACK WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
  4. {
  5.     SetWindowPos(FindWindow(L"Shell_traywnd", NULL ), 0, 0, 0, 0, 0, 0x40);
  6. }

字符串
不会这样做，它只显示已经可见=true的隐藏，但不会将其切换到/从自动隐藏。（同样适用于0x 80。）

当上面的代码实现时，只需通过以下方式将任务栏设置为自动隐藏：SetTaskbarState(AppBarStates.AutoHide);
通过以下方式获取当前状态：

  1. AppBarStates currentState = GetTaskbarState();

隐藏密码

这是一个比C#更与WIN32 API相关的问题。你可以使用this（当然需要翻译成dot net）来隐藏任务栏。
您可以使用http://www.pinvoke.net将WIN32 API调用转换为dot net。

将自动隐藏设置为隐藏

您可以通过使用描述here的键操作注册表来实现这一点。
这应该是一个简单的任务，祝你好运。

对于所有从谷歌来到这里并使用Windows 10的人来说，像我一样，来自@Quispie和@nicruo的答案是可以的，但需要额外的if。
原因是类名因版本而异（显然，因为我不再有任何其他Windows，但10）。

  1. msgData.hWnd = FindWindow("System_TrayWnd", null);
  2. if (msgData.hWnd == IntPtr.Zero)
  3.     msgData.hWnd = FindWindow("Shell_TrayWnd", null);
