How to run function in background in VB.NET?
提问by SharkTheDark
I am developing app in VB.NET that should have HTML requests and getting responses as string.
我正在 VB.NET 中开发应用程序，该应用程序应该具有 HTML 请求并以字符串形式获取响应。
Now I am using this code:
现在我正在使用此代码：
Dim URL as String = "http://domain.com/page.php"
Dim webClient As System.Net.WebClient = New System.Net.WebClient()
Dim result As String = webClient.DownloadString(URLL)
But when I run this code, my program froze for a little bit, until this URL content is loaded.
但是当我运行这段代码时，我的程序冻结了一点，直到加载了这个 URL 内容。
I searched over google and I didn't find anything about this. I tried using Classes and Modules, but with both of those it's frizzing again.
我在谷歌上搜索，我没有找到任何关于这个的信息。我尝试使用类和模块，但使用这两个它再次毛躁。
Can someone explain me how to run this in background, so program won't froze, and when it get's downloaded to return data?
有人可以解释我如何在后台运行它，这样程序就不会冻结，并且何时下载以返回数据？
Thanks.
谢谢。

I believe what you're looking for is the BackgroundWorker Class. This will allow you to spin the request off on a separate thread without freezing the UI. It's a pretty common thing.

Here's a couple of examples:
