VB.net Web浏览器 - 添加书签

Question

我有一个网络浏览器，我试图保持最小化以保持其快速运行（我有firefox gecko浏览器引擎，即使这对我认为这个问题并不重要。）但是有一个我要添加的东西，那就是书签。现在我有大量凌乱的代码，但每次点击书签按钮时我都无法创建新的工具条按钮。所以我做的是添加了适当的设置和6个工具条按钮。现在这限制了我6个书签。这真的很糟糕。我的代码在这里：

Imports System.IO

Public Class tabForm
    Dim ico As Image = Nothing

        ToolStripButton6.Text = My.Settings.mark66
        ToolStripButton6.Visible = True
    End If
  End Sub
End Class

这就是全部。但正如我之前所说，我只能添加6个书签。有什么办法可以添加无限数量的书签。我试过这样的事情：

Private Sub Bookmark()
  Dim mark As New ToolStripButton
  mark.DisplayStyle = Text
  mark.Parent = ToolStrip1 'This didn't work
End Sub

但是，如果我确实能够实现这一目标，我会将其导入到该页面？请帮忙。

我终于找到了答案。如果有人想知道链接在哪里：

度过愉快的一天。

Answer 1

创建一个名为favorite的类和一个名为favorites的收藏夹类型为system.collections.specialized.stringcollection

public class favorite
    inherits toolstripsplitbutton
    public mytitle as string
    public myurl as string
    public myimg as image
    public mybrowser as webbrowser

    public sub new(title as string, url as string, browser as webbrowser)
        mybase.new()

        mytitle = title
        myurl = url
        'create a getfavicon function - Google :)
        myimg = GetFavicon(myurl)
        mybrowser = browser
        me.text = mytitle
        me.tooltiptext = mytitle + " : " + myurl
        me.image = myimg
    end sub

    private sub Favorite_Click(sender as object, e as eventargs) handles me.click
        browser.navigate(myurl)
    end sub

然后在您的表单代码中添加一个子

public sub AddFav() handles '>>the add favorite button<<.click
    my.settings.favorites.add(webbrowser.documenttitle + "|" + webbrowser.url.tostring)
    my.settings.save()
end sub

public sub RefreshFavs()
    for each fav as string in my.settings.favorites
        dim favarray as array = fav.split(new char() {"|"c})
        dim x as new favorite(favarray(0), favarray(favarray.count - 1, webbrowser)
        mytoolstrip.items.add(x)
    next
end sub

简单的解释：

AddFav（） - 使用页面标题和网址

保存收藏夹

RefreshFavs（） - 通过＆＃34; |＆＃34;分割每个设置。标题和网址分开的

Class Favorite（） - 允许您添加一个拆分按钮，用于将链接的浏览器导航到它的myurl变量。

希望这会有所帮助。抱歉，如果它有点粗糙，我不得不从记忆中回忆起它。
