c++ - TrySubmitThreadpoolCallback 未声明的标识符

Question

环境

Win10、VC6.0

问题

当我使用windows默认线程池提交worker时， 它编译错误。我用的是VC6.0，包含了Windows.h 但它找不到该功能。请帮助我。

main.cpp

#include "main.h"

int KeyMap[128];



int main()
{
    ScriptHeadTail* pSht = (ScriptHeadTail*)KeyMap[101];
    if (pSht != NULL){
        TrySubmitThreadpoolCallback(ProcessHook, (LPVOID)(pSht->head), NULL);
    }

    Sleep(1000);

    return 1;
}


VOID CALLBACK ProcessHook(PTP_CALLBACK_INSTANCE instance, PVOID lParam)
{
    ExecuteScript* pScript = (ExecuteScript*)lpParam;
    while (pScript != NULL){
        switch (pScript->type)
        {
            case KEYBOARD :
            {
                printf("send key : %d\n", pScript->value);
                break;
            }
            case LBUTTON :
            {
                printf("left button down : %d\n", pScript->value);
                break;
            }
            case RBUTTON :
            {
                break;
            }
            case IDLE :
            {
                Sleep(pScript->value);
                break;
            }
        }
        pScript = pScript->next;
    }
    return 1;
}

ma​​in.h

#include <Windows.h>
#include <stdio.h>


struct ExecuteScript
{
    int type;
    int value;
    ExecuteScript* next;
};

struct ScriptHeadTail
{
    ExecuteScript* head;
    ExecuteScript* tail;
};

BOOL Init(LPCSTR configFile);
BOOL LoadConfigFile(const char* configFile);
VOID CALLBACK ProcessHook(PTP_CALLBACK_INSTANCE instance, PVOID lParam);

const int ASCII_LEN = 128;
const int KEYBOARD = 1;
const int LBUTTON = 2;
const int RBUTTON = 3;
const int IDLE = 4;

结果

该 API 是在 Windows Vista 中引入的。 VC 6 支持的最新 Windows SDK 适用于 Windows Server 2003，它比 Vista 更旧。

最好的修复方法是将 Visual C++ 升级到某个较新的版本。
