Question

我已经完成了将Gecko浏览器组件集成到现有winform控件的任务，但我面临的问题是如何配置dll，我也尝试使用不同的版本，但没有运气，它不加载DLL并给出错误

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

我已从指定链接单独下载。 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

导入System.Xml 进口壁虎导入Microsoft.Win32

Public Class Form1

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

结束班

如果有人已经做过，请帮助我。

最后我设法这样做了，

在撰写本文时，我选择了最新版本GeckoFX-33.0和XULRunner 33.1.，

打开GeckoFX-330.zip的包装，你会得到以下文件：
GeckoFx文件
如上所示添加对dll的引用，单击“浏览”并选择 Geckofx-Core.dll和Geckofx-Winforms.dll
在工具箱中，右键单击，然后选择“选择项目”，选择 Geckofx-Winforms.dll和Gecko winform控件将显示在工具箱
将GeckoWebBrowser控件拖到winform设计器中，然后让我们称之为“浏览”

在form1.cs文件中，添加以下代码：和最终代码：

            using System;
        using System.Collections.Generic;
        using System.ComponentModel;
        using System.Data;
        using System.Drawing;
        using System.Linq;
        using System.Text;
        using System.Windows.Forms;
        using System.Drawing.Printing;

        namespace GECKO_FORMS
        {
            public partial class Form1 : Form
            {
                Bitmap bitmap;
                Bitmap memoryImage;
                public Form1()
                {
                    InitializeComponent();
                    Gecko.Xpcom.Initialize(@"D:\\xulrunner\bin\\");
                }              
                private void cmdbrowse_Click(object sender, EventArgs e)
                {
                    try
                    {
                        if (browse.IsBusy == false)
                        {
                            browse.Navigate(textBox1.Text);
                        }
                        else
                        {
                            lbox.Items.Add(browse.StatusText);
                            lbox.Items.Add(browse.History);
                        }               
                    }
                    catch (Exception ex)
                    {
                        MessageBox.Show(ex.Message);
                    }
                }

                private void cmdstop_Click(object sender, EventArgs e)
                {
                    browse.Stop();
                }

                                                                private void browse_ProgressChanged(object sender, Gecko.GeckoProgressEventArgs e)
{
    lbox.Items.Add(e.CurrentProgress + " of " + e.MaximumProgress);
}
                                                                                                                                private void CaptureScreen()
{
    Graphics myGraphics = this.CreateGraphics();
    Size s = this.Size;
    memoryImage = new Bitmap(s.Width, s.Height, myGraphics);
    Graphics memoryGraphics = Graphics.FromImage(memoryImage);
    memoryGraphics.CopyFromScreen(this.Location.X, this.Location.Y, 0, 0, s);
}

                                                                                                                                                                                                                                                                                                                                                                                                                                private void cmdprint_Click(object sender, EventArgs e)
{
    try
    {
        CaptureScreen();
        pDoc.Print();
        ////Add a Panel control.
        //Panel panel = new Panel();
        //this.Controls.Add(panel);
        ////Create a Bitmap of size same as that of the Form.
        //Graphics grp = panel.CreateGraphics();
        //Size formSize = this.ClientSize;
        //bitmap = new Bitmap(formSize.Width, formSize.Height, grp);
        //grp = Graphics.FromImage(bitmap);

        ////Copy screen area that that the Panel covers.
        //Point panelLocation = PointToScreen(panel.Location);
        //grp.CopyFromScreen(panelLocation.X, panelLocation.Y, 0, 0, formSize);

        ////Show the Print Preview Dialog.
        //ppd.Document = pDoc;
        //ppd.PrintPreviewControl.Zoom = 1;
        //ppd.ShowDialog();
    }
    catch (Exception ex)
    {
    }
}        

                                                                private void pDoc_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
    e.Graphics.DrawImage(bitmap, 0, 0);
}
            }
        }
