3、假定这个新增按钮名称为"OpenQQ"，在菜单的SystemIdle事件增加以下代码：

\'此段代码用于显示OpenQQ的未读消息
Static OpenQQ As RibbonMenu.Button
Static LastTime As Date
If OpenQQ Is Nothing Then
    OpenQQ = ConfigBar.Items("OpenQQ")
End If
Dim txt As String
If QQClient.Ready
    If QQClient.UnreadCount > 0 Then
        txt = "(" & QQClient.UnreadCount & "条)"
    End If
End If
If OpenQQ.Text <> txt Then
    OpenQQ.Text = txt
End If
If OpenQQ.Text > "" Then
    Dim ntp As timeSpan = Date.Now - LastTime
    If ntp.TotalSeconds >= 0.5 Then
        LastTime = Date.Now
        If OpenQQ.ForeColor = Color.Red Then
            OpenQQ.ForeColor = Color.Transparent
        Else
            OpenQQ.ForeColor = Color.Red
        End If
    End If
End If
