多线程和进度条帮助 [英] Multithreading and progress bar help

问题描述

亲爱的专家，我想开发一个使用google

搜索网络服务的客户端应用程序。

在我的MainForm中我有一个检索所有搜索结果的方法例如

GetGoogleResults（）。

现在我希望在另一种形式中有一个很好的进度条，例如ProgressForm来执行搜索操作。

。 br />
i尝试这样做，但进度条不能工作，GUI冻结。

我知道如何处理单线程但我不知道如何在

多线程中做到这一点。

谁能给我一个如何做到这一点的例子。

谢谢

Dear experts, i want to develop an client application that consume the google
search web service.
In my MainForm i have a method to retrieve all the search result e.g.
GetGoogleResults().
Now i want to have a nice progress bar in another form e.g ProgressForm to
perform the search action.
i tried to do it but the progress bar won''t work and the GUI freezed.
I knew how to do with the single threading but i don''t know how to do it in
multiple threading.
Could anyone give me an example of how to do that.
Thank you
