Windows 7上的命名事件 [英] Named Events on Windows 7

问题描述

嘿朋友

有人在Windows 7中使用过命名事件吗?

在命名事件中挣扎，只能在XP上运行，而不能在Windows 7上运行.

Hey Friends

Has anybody used Named Events in Windows 7 ?

Struggling with Named Events, Works on XP , but not on Windows 7.

SharedEvent = CreateEvent(NULL, FALSE, FALSE, "ProblemWithWin7Events");

    if (SharedEvent == NULL)
    {

        AfxMessageBox("Cannot create named event!");
    }

    AfxBeginThread(ThreadProc,this);

并在线程中等待事件发信号

and in Thread Waiting for the Event to Signal

DWORD       WaitStatus;

    for(int vl_iIndex = 1; vl_iIndex <=1000;vl_iIndex ++)
    {
        WaitStatus = WaitForSingleObject(SharedEvent, INFINITE);

        if (WaitStatus != WAIT_OBJECT_0)
        {
            TRACE("%d WaitForSingleObject Failed\n",vl_iIndex );
        }
        else
        {

            TRACE("%d WaitForSingleObject Works\n",vl_iIndex );
        }
    }

还创建了一个按钮来通知事件

Also created a Button to Signal the Event

void CTestApplicationForEventsDlg::OnBnClickedSignalEvent()
{
    HANDLE vl_hEvent = OpenEvent(SYNCHRONIZE ,FALSE,"ProblemWithWin7Events");

    if(vl_hEvent ==NULL)
    {
        AfxMessageBox("Could not Open Event");
        return;
    }
    ::SetEvent(vl_hEvent);
}

知道我在做什么错吗?

关于

Any idea of what i am doing wrong ?

推荐答案

是否可以尝试使用EVENT_ALL_ACCESS而不是SYNCHRONIZE，如下所示?

Can you try using EVENT_ALL_ACCESS instead of SYNCHRONIZE as shown below??

HANDLE vl_hEvent = OpenEvent(EVENT_ALL_ACCESS, FALSE,"ProblemWithWin7Events");

是的，更改OpenEvent参数(访问参数，第一个参数)解决了该问题，非常感谢大家在这里为我提供帮助.

yeah changing OpenEvent Parameter (Access Parameter , the First Parameter) solved the problem, thanks a lot all of you for helping me out here.

HANDLE vl_hEvent = OpenEvent(EVENT_ALL_ACCESS, FALSE,"ProblemWithWin7Events");
