如何使用Vb.NET Forms配置“Gecko”应用

Question

我已经给出了将Gecko浏览器组件集成到现有winform控件的任务，但是im面临的问题是如何配置dll，我尝试使用不同的版本作为好了，但没有运气，在点它不会加载的dll，并给出了错误

Unable to find an entry point named 'NS_Alloc' in DLL 'xul'.

我从给定链路单独下载。 Xulrunner 最新的，也是29，但它说，

An error occurred creating the form. See Exception.InnerException for details. The error is: Unable to load DLL 'xul': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

Imports System.IO 

进口的System.Xml 进口壁虎 进口的Microsoft.Win32

公共类Form1中

Public Sub New() 
    InitializeComponent() 
    'D:\xulrunner\bin 
    Xpcom.Initialize("D:\\xulrunner\\") 'xulrunner 
    'Xpcom.Initialize("C:\Program Files (x86)\Mozilla Firefox\") 
End Sub 

结束类别

请帮助我，如果任何人已经完成了。

最后，我成功地做到这一点，

在写作的时候，我选择GeckoFX-33.0和XULRunner 33.1.最新版本，

• 拆开GeckoFX-330.zip，你会得到以下文件：

• GeckoFx文件

• 引用添加到上面显示的dll文件，单击浏览并选择 的Geckofx-Core.dll和Geckofx-Winforms.dll

• 在工具箱中，右键单击，然后选择“选择项”，选择 Geckofx-Winforms.dll和壁虎WinForm控件将在 显示工具箱
• 将一个GeckoWebBrowser控制WinForm设计，让我们 称之为“浏览”

• 在Form1.cs文件，添加如下代码： 终于CODE：
