I know how to do it in other languages, but not sure what best practice is for C++. As for exact tools, what's your recommendation? I am starting with windows.h

something along theses lines:

Code

#include <iostream>
#include <Windows.h>

int main() {
    // Get the current keyboard layout
    HKL keyboardLayout = GetKeyboardLayout(0);

    // Simulate a key press event
    INPUT input;
    input.type = INPUT_KEYBOARD;
    input.ki.wVk = VK_A;  // Press the 'A' key
    input.ki.dwFlags = 0;
    SendInput(1, &input, sizeof(INPUT));

    // Sleep to give the system some time to process the input
    Sleep(100);

    // Simulate a key release event
    input.ki.dwFlags = KEYEVENTF_KEYUP;
    SendInput(1, &input, sizeof(INPUT));

    // Get the keyboard state
    BYTE keyboardState[256];
    GetKeyboardState(keyboardState);

    // Buffer to store the Unicode result
    WCHAR result[2]; // Assuming a single Unicode character result

    // Call ToUnicodeEx to translate the virtual key code to Unicode
    int resultLength = ToUnicodeEx(VK_A, 0, keyboardState, result, 2, 0, keyboardLayout);

    // Check if the translation was successful
    if (resultLength > 0) {
        std::wcout << L"Unicode character: " << result[0] << std::endl;
    } else {
        std::wcout << L"Translation failed." << std::endl;
    }

    return 0;
}
