使用LowLevelKeyboardHook使用Alt Tab或者使用RegisterHotKey来Win Some Ubounded Key来使用Alt Tab键入快捷方式.只有使用LowLevelKeyboardHook的Win键才会出现问题.
在下面的示例中,当检测到Win Tab组合时,我接管了Win up事件.这样就可以使得以后的按键行为就像Win键仍然处于关闭状态.
private static IntPtr HookCallback(int nCode,IntPtr wParam,IntPtr lParam)
{
if (nCode != HC_ACTION)
return CallNextHookEx(_hookID,nCode,wParam,lParam);
var keyInfo = (Kbdllhookstruct)Marshal.PtrToStructure(lParam,typeof(Kbdllhookstruct));
if (keyInfo.VkCode == VK_LWIN)
{
if (wParam == (IntPtr)WM_KEYDOWN) {
_isWinDown = true;
} else {
_isWinDown = false;
if (_isWinTabDetected) {
_isWinTabDetected = false;
return (IntPtr)1;
}
}
}
else if (keyInfo.VkCode == VK_TAB && _isWinDown) {
_isWinTabDetected = true;
if (wParam == (IntPtr)WM_KEYDOWN) {
return (IntPtr)1;
} else {
_isWinTabDetected = true;
Console.WriteLine("WIN + TAB Pressed");
return (IntPtr)1;
}
}
return CallNextHookEx(_hookID,lParam);
}
}
}
您可以在这里找到完整的代码(请注意,它应该在一个空的WinForms项目中替换您的Program.cs以运行)：https://gist.github.com/christianrondeau/bdd03a3dc32a7a718d62 – 按Win Tab,每次按下快捷方式时,窗体标题应该更新.
Note that the intent of hooking into this specific combination is to provide an Alt + Tab alternative without replacing Alt + Tab itself. An answer providing the ability to launching custom code using Win + Tab will also be accepted.
这是我的想法,我找不到文档.所有这些都可能成功地回答我的问题.
>告诉Windows“取消”Win而不实际触发它
>防止Windows启动“开始”菜单一次
>直接钩在Windows的Win事件中,而不是手动钩入击键(这将是我的第一选择,如果存在)
解决方法
当您的应用失去焦点时,请慎重并注销此KB钩子！
[DllImport("user32.dll")]
static extern short GetAsyncKeyState(System.Windows.Forms.Keys vKey);
private static IntPtr HookCallback(int nCode,IntPtr lParam)
{
if (nCode == HC_ACTION)
{
var keyInfo = (Kbdllhookstruct) Marshal.PtrToStructure(lParam,typeof (Kbdllhookstruct));
if ((int) wParam == WM_KEYDOWN
&& keyInfo.VkCode == VK_TAB
&& (GetAsyncKeyState(Keys.LWin) < 0 || GetAsyncKeyState(Keys.RWin) < 0))
{
_mainForm.Text = "Win + Tab was pressed " + (++_winTabPressCounter) + " times";
return (IntPtr) 1;
}
}
return CallNextHookEx(_hookID,lParam);
}
在发现这种技术之前,我尝试过几件事情.
