特殊字符keybd_event C++

Question

I have a string with special character, like this std::string test = "hello é -"; I want write this string with keybd_event but special characters wasn't good display. I do this :

std::string result = "Hello é -";
int taille = result.size ();

for (int i = 0 ; i < taille ; i++)
{
    keybd_event(VkKeyScan(result.at(i)),0x9e,0 , 0);
    keybd_event(VkKeyScan(result.at(i)),0x9e, KEYEVENTF_KEYUP,0);
}

I did some research and found std::wstring for unicode but even with that it doesn't work, any idea ?

Answer 1

You need to use SendInput() instead of keybd_event() , eg:

std::wstring result = L"Hello é -";
int taille = result.size ();

std::vector<INPUT> inputs(taille);

for (int i = 0; i < taille; ++i)
{
    INPUT &input = inputs[i];
    input.type = INPUT_KEYBOARD;
    input.ki.wVk = 0;
    input.ki.wScan = result.at(i);
    input.ki.dwFlags = KEYEVENTF_UNICODE;
    input.ki.time = 0;
    input.ki.dwExtraInfo = GetMessageExtraInfo();
}

SendInput(inputs.size(), &inputs[0], sizeof(INPUT));
