如何获得毫秒级的系统时间?

Question

SYSTEMTIME systime;
GetLocalTime(&systime);
TCHAR tcsystime[1024];
_stprintf(tcsystime,"%d/%d/%d,%d:%d:%d:%d  ",systime.wYear,systime.wMonth,systime.wDay,systime.wHour,systime.wMinute,systime.wSecond,systime.wMilliseconds);

Answer 1

//Decription: delay timeS
void CIdeApp::let_msg_go_and_wait(DWORD dwMS)
{
    DWORD dwStart; 
    MSG msg;    dwStart=::GetTickCount();
cont_wait:
    while ( ::PeekMessage( &msg, NULL, 0, 0, PM_REMOVE ) )
    {
        if ( msg.message==WM_QUIT )
        {
            ::PostQuitMessage(-1);
            break;
        }
        if (!AfxGetApp()->PreTranslateMessage(&msg))
        {
            ::TranslateMessage(&msg);
            ::DispatchMessage(&msg);
        }
    }
    AfxGetApp()->OnIdle(0);
    AfxGetApp()->OnIdle(1);
    if (dwMS==0) return;
    if ((::GetTickCount()-dwStart)<dwMS) goto cont_wait;
}
这是消息处理的时间delay,应该可以！

另外CSDN上也有个例子

给分吧，人家计算CPU频率，然后计算时钟周期，没有比这更准的了！标题最后一栏，管理~
