控制台程序的 定时器 和 消息循环

SetTimer实现定时器，需要Windows消息循环！！！

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

void CALLBACK TimerProc(HWND   hwnd,UINT   uMsg,UINT   idEvent,DWORD   dwTime) 
{ 
    std::cout<<"hello "<<std::endl; 
} 

void main() 
{ 
    int timerID = 1; 
    MSG msg; 
    
    SetTimer(NULL,timerID,1000,TimerProc); 
    
    while ((GetMessage(&msg, NULL, NULL, NULL) != 0) && (GetMessage(&msg, NULL, NULL, NULL) != -1))
    { 
        if (msg.message == WM_TIMER) 
        { 
            std::cout<<"i got the message."<<std::endl; 
            TranslateMessage(&msg); 
            DispatchMessage(&msg); 
        } 
    } 
}
