Named Events on Windows 7

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);

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 );
        }
    }

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);
}

Any idea of what i am doing wrong ?
