基本上，我要做的是让GetKeyboardLayoutName返回其他进程的键盘ID（KLID）。默认情况下，它仅重新设置应用程序窗口的键盘ID。我也尝试了GetKeyboardLayout，但它不幸地返回了一个HKL（它接受了另一个窗口的hwnd）。
或者，如果有办法将HKL转换为KLID，那也会很棒，但我怀疑是否有这样的事情。
那么，我怎样才能做到这一点？我希望能够将获得的KLID用作LoadKeyboardLayout函数的参数。

我找到了一种解决方法，以便能够检索另一个应用程序的键盘布局。这个过程很简单：
使用GetKeyboardLayout在其他应用中获取键盘语言的HKL。要获取其他应用程序的句柄，可以使用GetForegroundWindow获取窗口的句柄，然后使用GetWindowThreadProcessId获取具有先前检索的窗口句柄的进程句柄。
使用ActivateKeyboardLayout将以前提取的HKL设置为我的应用程序的键盘句柄。
获取我的应用程序的键盘语言ID（KLID）。
最后，我的应用程序将使用与其他应用程序相同的键盘语言，从我的应用程序中，我可以轻松地提取KLID。 这是我在项目中使用的示例代码。希望它也能帮到你。
using System.Runtime.InteropServices;
...
StringBuilder Input = new StringBuilder(9);
[DllImport("user32.dll")]
static extern uint GetKeyboardLayoutList(int nBuff, [Out] IntPtr[] lpList);
[DllImport("user32.dll")]
private static extern IntPtr LoadKeyboardLayout(string pwszKLID, uint Flags);
[DllImport("user32.dll")]
static extern bool GetKeyboardLayoutName([Out] StringBuilder pwszKLID);
[DllImport("user32.dll")]
static extern IntPtr GetKeyboardLayout(uint idThread);
[DllImport("user32.dll")]
private static extern IntPtr GetForegroundWindow();
[DllImport("user32.dll")]
static extern uint GetWindowThreadProcessId(IntPtr hWnd, IntPtr ProcessId);
[DllImport("user32.dll")]
public static extern int ActivateKeyboardLayout(int HKL, int flags);
private static extern bool PostMessage(int hhwnd, uint msg, IntPtr wparam, IntPtr lparam);
private static uint WM_INPUTLANGCHANGEREQUEST = 0x0050;
private static int HWND_BROADCAST = 0xffff;
private static uint KLF_ACTIVATE = 1;
...
public StringBuilder GetInput()
{
IntPtr layout = GetKeyboardLayout(GetWindowThreadProcessId(GetForegroundWindow(), IntPtr.Zero));
ActivateKeyboardLayout((int)layout, 100);
GetKeyboardLayoutName(Input);
return Input;
}
public void SetInput(string InputID)
{
PostMessage(HWND_BROADCAST, WM_INPUTLANGCHANGEREQUEST, IntPtr.Zero, LoadKeyboardLayout(InputID, KLF_ACTIVATE));
}
方法GetInput()返回一个StringBuilder，可以使用ToString()将其转换为字符串，然后使用SetInput()等方法设置键盘语言。

我只是想留下这个，以防其他人需要知道每个代码代表什么。我花了几个小时手工制作这份清单。它是每个布局代码到我的Windows 7版本可用的布局名称的映射。我不得不手工输入名字，所以请原谅任何错别字。代码以编程方式收集。
