WebBrowser网站超时

这适用于Visual Studio Express 2012中的Desktop C＃应用程序。

我使用webBrowser控件登录到各种网站，但发现一些没有响应和超时。

我怀疑它可能是webBrowser控件固有地运行IE7，但发现这些网站在运行IE7作为本机浏览器的旧PC上运行良好。 我是否需要设置webBrowser中的某些内容以允许诸如下面代码中的网站来处理响应？

下面的代码导航到我遇到问题的网站。 如果在本机浏览器中输入Login和Password的任何值，它会立即响应并抛出错误，但在webBrowser中它会在那里等待响应并最终超时。

任何帮助将不胜感激！

我经常使用WenBrowserControl工作，甚至不记得有一次我没有任何问题，尤其是控件的browermode。 以下是帮助我解决许多这些问题的一些步骤：

1）强制应用程序使用InternetExplorer设置：首先，我建议您尝试为您的应用程序添加注册表项

 HKLM\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION 

和

 HKLM\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION` 

使用值9000强制应用程序中的控件使用IE9设置。 在这里，您可以找到使我了解此问题的问题。 它的描述非常详细。

2）Internet Explorer中的设置：超时问题对我来说就像IE的一些安全function阻塞了一些东西。 在我的意见中，Internet Explorer对网站内容有相关规定。 尝试将超时的网站添加到IE的Internetsettings下的安全站点。 还要尝试降低安全站点的安全性/阻止function。

如果你有任何进一步的请告诉我。

这是完整的工作代码：
