使用Sendinput以及GetAsyncKeyState来模拟按键延时

Code:

#include <windows.h>
#include <tchar.h>
#include <iostream>

BOOL flag = TRUE;

DWORD WINAPI ThreadProc2(LPVOID lpParameter)
{
    INPUT input[];
    ZeroMemory(&input, sizeof(input));
    input[].ki.wVk = input[].ki.wVk = 0x45;
    input[].type = input[].type = INPUT_KEYBOARD;
    while (true)
    {
        if (GetAsyncKeyState(VK_NUMPAD0) & 0x8000)
        {
            flag = TRUE;
            SetForegroundWindow(HWND(0x00060A3E)); //HWND is used for testing
            input[].ki.dwFlags = ;
            input[].ki.dwFlags = KEYEVENTF_KEYUP;
            SendInput(, input, sizeof(INPUT));
            Sleep();
            while (flag)
            {
                input[].ki.dwFlags = ;
                input[].ki.dwFlags = KEYEVENTF_KEYUP;
                SendInput(, input, sizeof(INPUT));
                Sleep();
            }

        }
    }
}

DWORD WINAPI ThreadProc1(LPVOID lpParameter)
{
    while (true)
    {
        if (GetAsyncKeyState(VK_NUMPAD0) & 0x8000)
        {
            Sleep();
            flag = FALSE;

        }
        else if (GetAsyncKeyState(VK_END) & 0x8000)
        {
            exit();
        }
    }

}

int main()
{
    DWORD tid1 = ;
    DWORD tid2 = ;
    HANDLE hThread1 = CreateThread(NULL, , ThreadProc1, NULL, , &tid1);
    HANDLE hThread2 = CreateThread(NULL, , ThreadProc2, NULL, , &tid2);

    getchar();
    return ;
}

使用了两个线程，一个用于重复发送SendInput，一个用于计时
