问题描述

大家好，


我现在正试图通过工作人员

线程上的Timer控件来更新状态指示器。状态指示器只是主窗体上的标签，但是我很难确定如何实现单独的工作程序

线程或异步委托更改标签内容基于

计时器控件的标记。那里有什么好的例子，你可以吗？
把我指向一两个？


谢谢，

Michael C.

解决方案

似乎问题是在SqlClient上发出SqlCommands似乎

完全接管当前线程。我以为我可以通过一个简单的Timer控件在UI线程上完成这一切，但这不会发生在''。关于如何在SqlCommand期间让我的Timer控件切换到
执行的任何

想法？这将是一个比单独的线程更简单和更好的解决方案。但如果有必要的话，我愿意接受一个单独的工作线程。


提前谢谢，

Michael C.

感谢您的链接。他的书中有相同的示例代码（Windows

C＃中的表单编程）。问题是它没有解决我的实际问题，

这就是我正在执行的SQL查询似乎阻止了Timer（）控件

Tick事件从执行。即使我在

单独的线程上运行状态更新代码，就像在他的书中一样......我如何让我的Timer（）勾选为

它应该是到？


谢谢，

Hi all,

I''m now trying to update a status indicator via a Timer control on a worker
thread. The status indicator is just a label on the main form, but I''m
having trouble figuring out exactly how to implement a separate worker
thread or asynchronous delegate that changes the label contents based on the
Timer control''s ticks. Are there any good examples out there and can you
point me to one or two?

Thanks,
Michael C.

解决方案

It seems that the issue is that issuing SqlCommands on a SqlClient seems to
take over the current thread completely. I thought I could do this all on
the UI thread with a simple Timer control, but that ain''t happenin''. Any
ideas on how I can get my Timer control to Tick during SqlCommand
executions? That would be a much simpler and preferable solution than a
separate thread. But I''m open to a separate worker thread if necessary.

Thanks in advance,
Michael C.

Thanks for the link. He has the same example code in his book (Windows
Forms Programming in C#). Problem is that it doesn''t solve my real problem,
which is that the SQL Query I''m executing seems to block the Timer() control
Tick event from ever executing. Even when I run the status update code on a
separate thread like in his book... How can I make my Timer() Tick like
it''s supposed to?

Thanks,
Michael C.
