I am trying to get the key-value for a particular scan-code in various languages
int the following way
Layout: English United States (US keyboard)
16 - Q
17 - W
18 - E
19 - R
20 - T
21 - Y
Layout: French (France Keyboard)
16 - A
17 - Z
18 - E
19 - R
20 - T
21 - Y
for this, I use the following code:
#include "pch.h"
#include "iostream"
#include <windows.h>
using namespace std;
int main()
{
int scancode[6] = { 16,17,18,19,20,21};
int bufferLength = 10;
char buffer[10] ;
while (1)
{
int i = 0;
for (i = 0; i < 6 ; i++)
{
unsigned int extended = scancode[i] & 0xffff00;
unsigned int lParam = 0;
if (extended)
{
if (extended == 0xE11D00)
{
lParam = 0x45 << 16;
}
else
{
lParam = (0x100 | (scancode[i] & 0xff)) << 16;
}
}
else {
lParam = scancode[i] << 16;
if (scancode[i] == 0x45)
{
lParam |= (0x1 << 24);
}
}
GetKeyNameTextA(lParam, buffer, bufferLength);
printf("%s \n", buffer);
}
}
return 0;
}
This code gives me the localized key values but if I change the layout at run time the key values are not changed. They remain the same as before, to get the changed values I have to run it again. Can anyone suggest me a fix for it?? Also suggest if there is an alternative way to acheive this..
Use LoadKeyboardLayout and send WM_INPUTLANGCHANGEREQUEST to change the keyboard layout as follows:
#include <iostream>
#include <string>
#include <windows.h>
int main()
{
HKL hkl = LoadKeyboardLayout(L"0000080c", KLF_ACTIVATE);
PostMessage(GetConsoleWindow(), WM_INPUTLANGCHANGEREQUEST, 0, (LPARAM)hkl);
std::string str;
while(std::cin >> str)
if(str == "0")
break;
return 0;
}
