请帮助多线程 [英] please help on multithreading
问题描述
我有一个使用多线程的严重问题。一个示例应用程序
显示我的问题可以在这里下载：
http://graphicsxp.free.fr/WindowsApplication11.zip
问题是我需要从
$调用控件上的操作b $ b委托，否则它不起作用。但是每次我完成
操作时，我必须更新进度条和progresslabel，但是这个
不能在委托中完成，因为它不起作用。 br />
在示例中我刚刚做了一个循环来增加进度条，但实际上
的进度条更新和操作
控件（tabcontro，datagrid ..）应该嵌套，因此问题！
请查看示例，以便更清楚地了解我在尝试什么
来实现。
感谢您的帮助:)

Ken，
感谢您的链接，但它几乎就是我已经做过的事情。请查看我的示例应用程序。
。你能告诉我你是否第一眼看到了什么'b $ b错了？
谢谢
你好，
我仍然在努力修复这个问题。有人看过我的
代码吗？
如果有人能发现我做错了，我会很感激。
问候
Hi,
I have a serious issue using multithreading. A sample application
showing my issue can be downloaded here:
http://graphicsxp.free.fr/WindowsApplication11.zip
The problem is that I need to call operations on Controls from a
delegate, otherwise it does not work. However each time I''ve done an
operation, I must update the progressbar and progresslabel, but this
cannot be done in the delegate as it does not work.
In the sample I''ve just done a loop to increase the progressbar, but
obviously in reality the progressbar updates and the operations on
controls (tabcontro, datagrid..) should be nested, hence the issue!
Please have a look at the sample for a clearer idea of what i''m trying
to achieve.
Thanks for your help:)

Ken,
Thanks for the link but it''s pretty much what i do already. please have
a look at my sample application. Can you just tell me if you see what''s
wrong at first sight ?
thank you
Hello,

I would be gratefull if someone could spot what I''m doing wrong.
