我很高兴看到在VB 2005中我不再需要创建一个表单，如果我想要像我在VB6中那样使用计时器。我注意到，似乎有一个Timer 组件以及两个不同的计时器类从（System.Threading& System.Timers）中选择 。 br /> 如何确定哪种最适合任何特定的应用程序？ 我目前的应用程序是一种实时数据采集&控制 系统，我需要每100ms左右轮询一次外部设备。 TIA Phil。

I''m glad to see that in VB 2005 I no longer have to create a form if I want a timer like I did in VB6. I notice though, that there seems to be a Timer component as well as two different timer classes to choose from(System.Threading & System.Timers). How does one decide which is most appropriate for any particular application? My current application is a sort of real-time data acquisition & control system, and I need to poll an external device every 100ms or so. TIA Phil.

嗨菲尔， 由于您当前的应用程序是实时数据采集和控制 系统，您应该使用基于服务器的计时器，即System.Timers.Timer。 希望这会有所帮助。 如果您有任何疑问，请随时告诉我。 此致， Linda Liu Microsoft在线社区支持 ================== ================================ 通过电子邮件收到我的帖子通知？请参阅 msdn.microsoft / subscripti ... ult.aspx＃notif ications。 注意：MSDN托管新闻组支持服务是针对非紧急问题 如果社区或微软支持人员在1个工作日内做出初步回复是可以接受的。请注意，每个跟随 的响应可能需要大约2个工作日作为支持 专业人士与您合作可能需要进一步调查才能达到 最有效的分辨率。该产品不适用于需要紧急，实时或基于电话的交互或复杂的b $ b项目分析和转储分析问题的情况。这种性质的问题最好通过联系 Microsoft客户支持服务（CSS）处理 href =msdn.microsoft/subscriptions/support/default.aspx\"target =_ blank> msdn.microsoft/subscripti...t/default.aspx 。 ======================================== ========== 此帖子按原样提供。没有保证，也没有授予任何权利。 Hi Phil, Since that your current application is a real-time data acquisition&control system, you should use the server-based timer, i.e. System.Timers.Timer.
