多线程问题......帮助 [英] multi-threading problem...help
问题描述
好的，
我有一个线程，我在用户点击开始时启动：
ThreadStart myThreadDelegate = new ThreadStart
ThreadFunction1.getOneAtATime）;
线程thr1 =新线程（myThreadDelegate）;
thr1.Start（）;
进程开始包含一个非常大的函数，它在一个连续循环的
中（这里只是为了演示我的问题）：
foreach（字符串发票）在Class1.invoiceHolder中）
{
//不断显示状态栏
//不断更新图像控制如果托盘有纸或不是。
//不断更新显示发票信息的标签
}
好的，
这需要在这个循环中一次运行几天......但是，如上所述，我在线程中有了它的b $ b，应用程序就会退出。
我之前发过一个问题并得到了答案
"控件创建者在其他线程中启动的
进程不应触及初始化线程（创建不良结果）。好的，
我明白了，但是当我开始运行这个帖子时，它必须给
用户更新。
好的，我看了在Control.Invoke并没有得到它。我的意思是，我/ b $ b无法弄清楚如何使用它（精神障碍）。这是我的问题的答案吗？ （问题是，如果我没有在单独的线程中启动这个巨大的进程，当它在这个循环中启动时，计算机开始
爬行）。 br />
帮助表示赞赏。
谢谢，

Ok,
I have a thread that I start when user clicks to start:
ThreadStart myThreadDelegate = new ThreadStart
ThreadFunction1.getOneAtATime);
Thread thr1 = new Thread(myThreadDelegate);
thr1.Start();
The process started contains a Very large function that is in a
continuous loop (here is part of it just to demonstrate my problem):
foreach (string invoice in Class1.invoiceHolder)
{
//Constantly show a status bar
//Constantly update image control of "if tray has paper or not".
//Constantly update labels displaying info about Invoices
}
Ok,
This will need to run for days at a time in this loop...HOWEVER, I had
it in the Thread, as mentioned, and the app would just quit.
I had posted a question to this before and got the answer that
"Controls created by the initializing thread should not be touched by
processes started in other threads (creates undesirable results". Ok,
I get that, but when this thread I start runs, it MUST give updates to
users.
Ok, I have looked at Control.Invoke and don''t get it. I mean that, I
couldn''t figure out how to use it (mental block). Is that the answer to
my problem? (Problem being, that if I don''t start this giant process in
a separate thread, when it starts in this loop, the computer starts to
crawl).
Help is appreciated.
Thanks,
Trint
推荐答案
我应该启动两个线程，一个执行工作，一个（使用计时器）
每隔xxx时间更新一次用户状态。
但是......你为什么不做一个与前端通信的服务？
QueueMessage或其他技术？
I whould start two thread, one that do the work, and one (using timers)
that updates the status to the user every xxx time.
But... why don''t you do a service that comunicate with a front-end with
QueueMessage or other tecnics?
不错，但是他们已经批准了表格上的控件外观
。
我确实需要这个大功能虽然在一个新的线程中。
谢谢。
Not a bad idea, but they have already approved the look of the controls
on the forms.
I do need to have this large function in a new thread though.
Thanks.
你好Trint ..
这篇文章是在VB中并且解释了很多关于线程并在它们之间传递
的值，看它是否有帮助

Hi Trint..
This article is in VB and explains pretty much about threads and passing
values between them, see if it helps
