Get current active Language keyboard

Question

I want get active language keyboard

for get active language i use this function :

WCHAR name[256];

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

LANGID language = (LANGID)(((UINT)lang) & 0x0000FFFF); // bottom 16 bit of HKL is LANGID
LCID locale = MAKELCID(language, SORT_DEFAULT);

GetLocaleInfo(locale, LOCALE_SLANGUAGE, name, 256);

return CString(name);

but this function retrieve One last with the last change (not new language), but i want to get new language, what is problem? what is wrong?

Please clarify what you mean by "active language keyboard". Please also explain the steps to see that it only shows the last change. — Robert Andrzejuk, Jan 20 '18 at 15:24

From the doucmentation (GetKeyboardLayout function), when a 0 is used as a default parameter it gets the keyboard layout from the current thread:

HKL lang = ::GetKeyboardLayout(0);

To create a language id, the following macro is used:

#define MAKELANGID(p, s)       ((((WORD  )(s)) << 10) | (WORD  )(p))

Also defined are the following helper macros:

#define PRIMARYLANGID(lgid)    ((WORD  )(lgid) & 0x3ff)
#define SUBLANGID(lgid)        ((WORD  )(lgid) >> 10)

So I just fixed up the code to be:

LANGID language = PRIMARYLANGID(lang);

And it works correctly for me.

To listen to keyboard changes the WM_INPUTLANGCHANGE message should be processed.

Actually you have to have a message loop in the thread specified otherwise changes to the language are not detected until you restart the app, a console app is a good example.[2]

@Mr.DeveloperCplus Did this help? – Robert Andrzejuk Jan 24 '18 at 14:29
tanks for your help, But actually this not correct answer and when I change language it's tell me language is English, But isn't, I want use this code in Key-logger. – Mr.DeveloperCplus Jan 27 '18 at 09:01
if put this code in while loop with condition true it demonstrate first language – Mr.DeveloperCplus Jan 27 '18 at 09:12

If you did a for, do, while loop - it is wrong. You need a message pump loop. https://stackoverflow.com/a/2223270/2504757. But You need a window id for this to work correctly. This should be done in a GUI app, not a console app. – Robert Andrzejuk Jan 27 '18 at 10:04
