web瀏覽器的網站超時

Question

這是在Visual Studio Express的2012

我使用WebBrowser控件登錄到不同的網站，但發現一些不響應並且超時桌面C＃應用程序。

我懷疑它可能是固有運行IE7的webBrowser控件，但發現這些網站在運行IE7的舊PC上運行良好，作爲本機瀏覽器。我需要設置webBrowser中是否存在某些網站，例如下面代碼中的網站來處理回覆？

下面的代碼導航到我遇到問題的網站。如果您在本機瀏覽器中輸入登錄名和密碼的任何值，它會立即響應並引發錯誤，但在webBrowser中，它位於此處等待響應並最終超時。

任何幫助將不勝感激！

Answer 2

我與WenBrowserControl經常工作，真的不記得，甚至有一次，我沒有任何問題，特別是與控制的browermode。以下是一些步驟，幫助我解決很多這樣的問題：

1）強制應用程序使用InternetExplorer的設置： 首先我建議你嘗試下

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

，並增加了對您的應用程序的註冊表項

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

與值9000這迫使您的應用程序中的控件使用IE9設置。 Here你可以找到將我帶到這個解決方案的問題。其描述非常詳細。

2）在Internet Explorer中的設置： 超時問題尋找我喜歡IE的某些安全功能阻塞的東西。在我看來，Internet Explorer對網站內容有相當規定。嘗試將超時網站添加到IE的Internetsettings下的安全網站中。也嘗試減少安全站點的安全/阻止功能。

請讓我知道，如果你有任何進一步的。
