无法获取当前的键盘布局 [英] can't get current keyboard layout

问题描述

我尝试使用 GetKeyboardLayoutName()和 GetKeyboardLayout()来获取当前的键盘布局，但是它们都为我提供了默认布局，并且更改布局不会影响输出！

I have tried GetKeyboardLayoutName() and GetKeyboardLayout() for getting the current keyboard layout, but they both give me the default layout and changing the layout doesn't affect the output!

while(1)
{
    Sleep(5);
    for(int i = 8; i < 191; i++)
    {
        if(GetAsyncKeyState(i)&1 ==1)
        {
            TCHAR szKeyboard[KL_NAMELENGTH];
            GetKeyboardLayoutName(szKeyboard);

            if(GetAsyncKeyState(i)&1 ==1)
            {
                TCHAR szKeyboard[KL_NAMELENGTH];
                GetKeyboardLayoutName(szKeyboard);
                cout << szKeyboard << endl ;
            }
        }
    }
}

当默认布局设置为英语时，它总是给我"00000409"，而当我将布局更改为波斯语时，我希望它是"00000429".

It always gives me "00000409" when the default layout is set to English, while I expect it to be "00000429" when I change the layout to Farsi.

我的第一个问题是，我过去经常通过搜索找到所有答案.但是现在，经过数小时的搜索却一无所获之后，我现在开始发疯了.

My first question here, I used to find all my answers by just searching. But right now I'm driving crazy after hours of searching around and getting nothing...

推荐答案

您需要注意的一件事是:: GetKeyboardLayout(..)将传递的线程标识符的lang作为参数.

one thing that you need to notice is that ::GetKeyboardLayout (..) gets the lang for the passed thread identifer as a param.

每个输入线程可以具有不同的输入语言环境lang. 例如，如果您将IE放在前台，然后按Alt + Shift，则将lang更改为UK. (您可以在任务栏中看到它)

each input thread can have different input locale lang. for instance if you put lets IE in the foreground and press Alt+Shift the lang changes to UK. ( you can see it in the taskbar )

现在，如果您将Alt + Tab转到另一个窗口(该窗口将处于foregorund中)，您将看到lang不必留在英国.

now if you will Alt+Tab to another window ( which will be in foregorund ) you will see that lang dont have to stay UK.

所以您需要检查的是您要传递的线程ID.

so what you need to check is what is the thread id you are passing.

看看下面的代码，它将为您提供当前活动窗口的语言:

look at this code it will get you the lang for the current active window:

GUITHREADINFO Gti;
::ZeroMemory ( &Gti,sizeof(GUITHREADINFO));
Gti.cbSize = sizeof( GUITHREADINFO );
::GetGUIThreadInfo(0,&Gti);
DWORD dwThread = ::GetWindowThreadProcessId(Gti.hwndActive,0);
HKL lang = ::GetKeyboardLayout(dwThread);

要使用GUITHREADINFO，您需要定义WINVER 0x500. 在所有包含之前将其放在stdafx.h中.

to use GUITHREADINFO you need to define WINVER 0x500. put this in the stdafx.h before all the include.

#ifdef WINVER
#undef WINVER
#endif 
#define WINVER 0x500
