How to handle downloading in GeckoFX 29

Question

How can I handle downloading in GeckoFx I\'m using version 29 I\'ve found some ways like adding event of
LauncherDialog_Download(

Answer 1

In form load after your

browser.navigate("http://www.domain.com");

Use this:

LauncherDialog.Download += LauncherDialog_Download;

Create LauncherDialog_Download

void LauncherDialog_Download(object sender, LauncherDialogEvent e)
    {
        nsILocalFile objTarget = Xpcom.CreateInstance("@mozilla.org/file/local;1");

        using (nsAString tmp = new nsAString(@Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + "\temp.tmp"))
        {
            objTarget.InitWithPath(tmp);
        }

        //Save file dialog
        Stream myStream;
        SaveFileDialog saveFileDialog1 = new SaveFileDialog();

        saveFileDialog1.Filter = "All files (*.*)|*.*";
        saveFileDialog1.FilterIndex = 2;
        saveFileDialog1.RestoreDirectory = true;
        saveFileDialog1.FileName = e.Filename;

        if (saveFileDialog1.ShowDialog() == DialogResult.OK)
        {
            if ((myStream = saveFileDialog1.OpenFile()) != null)
            {
                nsIURI source = IOService.CreateNsIUri(e.Url);
                nsIURI dest = IOService.CreateNsIUri(new Uri(@saveFileDialog1.FileName).AbsoluteUri);
                nsAStringBase t = (nsAStringBase)new nsAString(System.IO.Path.GetFileName(@saveFileDialog1.FileName));

                nsIWebBrowserPersist persist = Xpcom.CreateInstance("@mozilla.org/embedding/browser/nsWebBrowserPersist;1");
                nsIDownloadManager DownloadMan = null;
                DownloadMan = Xpcom.CreateInstance("@mozilla.org/download-manager;1");
                nsIDownload download = DownloadMan.AddDownload(0, source, dest, t, e.Mime, 0, null, (nsICancelable)persist, false);

                if (download != null)
                {
                    persist.SetPersistFlagsAttribute(2 | 32 | 16384);
                    persist.SetProgressListenerAttribute((nsIWebProgressListener)download);
                    persist.SaveURI(source, null, null, null, null, (nsISupports)dest, null);
                }

                myStream.Close();
            }
        }
    }

The above code also triggers saveFileDialog so your program will ask where you want to save the file.

Tested and working with GeckoFX 31 and 33 but should work in 29 as well. If it doesn't, download the latest GeckoFX from here.

And Xulrunner from here.
