Web Browser in C# - Code. Project. Contents. This was my first project in C#. This article describes how to implement some of the features of a Web Browser application like managing tabs, viewing the favicon of a particular website, managing Favorites websites and Links Bar, viewing the History, searching on Google or Live Search, saving settings between application runs, viewing the source and properties of a website, printing the content of page, and others.
ยท Example: A Simple Web Browser Now that we know how to generate and reference an ActiveX Assembly that wraps an ActiveX control as a Windows Forms control, we'll put together a short example that uses an ActiveX. C# has a Web. Browser control that does all the work of rendering web pages. In my main form, I added a Tab. Control control named browser. Tab. Control with only one Tab. Page which represents the "New" tab. When the user clicks the "New" tab, then a new tab is created. The add. New. Tab() method shows how to add a new tab in your web browser. New. Tab(). Tab. Page tpage = new Tab. Page(). tpage. Border. Style = Border. Style. Fixed. 3D. browser. Tab. Control. Tab. Pages. Insert(. browser. Tab. Control. Tab. Count - 1, tpage). Web. Browser browser = new Web. Browser(). browser. Navigate(home. Page). Controls. Add(browser). Dock = Dock. Style. Fill. browser. Tab. Control. Select. Tab(tpage). Progress. Changed += new. Web. Browser. Progress. Changed. Event. Handler(Form. Progress. Changed). Document. Completed += new. Web. Browser. Document. Completed. Event. Handler(Form. 1_Document. Completed). browser. Navigating +=. new Web. Browser. Navigating. Event. Handler(Form. Navigating). browser. Can. Go. Back. Changed +=. Event. Handler(browser_Can. ![]() Go. Back. Changed). Can. Go. Forward. Changed +=. new Event. Handler(browser_Can. Go. Forward. Changed). The example below shows how to get the current tab: private Web. Browser get. Current. Browser(). return (Web. Browser)browser. Tab. Control. Selected. Tab. Controls[0]. A favicon is a 1. X1. 6, 3. 2X3. 2, or 6. X6. 4 pixel square icon associated with a website. This icon is called favicon. What you have to do in order to get the favicon of a particular website is to make a request to http: //websitename/favicon. You can get the icon from the response stream and use it in your application. For websites that don't have a favicon, I have used a default icon. Image favicon(String u, string file). Uri url = new Uri(u). String iconurl = "http: //" + url. Host + "/favicon. Web. Request request = Web. Request. Create(iconurl). Web. Response response = request. Get. Response(). Stream s = response. Get. Response. Stream(). Image. From. Stream(s). Exception ex). return Image. From. File(file). For the Links Bar, I used a Tool. Strip control. A link button is represented by a Tool. Strip. Button with the favicon image, and the website name as the text displayed on the button. The links are stored in an XML file that looks like this: < favorits> < linkurl="http: //www. Google/< link> < linkurl="http: //www. Code. Project< /link> < linkurl="http: //www. Youtube/Edu< /link> < /favorits> The add. New. Link() method shows how to add a new link. First, you open the XML file containing the links, then add a new Xml. Element, setting the url attribute with the address of the website and the inner text of this element with the name you want this link to appear on the links bar. Then, you add a Tool. Strip. Button to the links bar. The Tool. Strip. Button control has a constructor that takes four arguments: public Tool. Strip. Button(string text, Image image, Event. Handler on. Click, string name). Link(String url, string name). Xml. Document my. Xml = new Xml. Document(). Xml. Element el = my. Xml. Create. Element("link"). Set. Attribute("url", url). Inner. Text = name. File. Exists(links. Xml)). Xml. Element root = my. Xml. Create. Element("links"). Xml. Append. Child(root). Append. Child(el). Xml. Load(links. Xml). Xml. Document. Element. Append. Child(el). Bar. Visible == true). Tool. Strip. Button b =. Tool. Strip. Button(el. Inner. Text, get. Favicon(url). items_Click, el. Get. Attribute("url")). Tool. Tip. Text = el. Get. Attribute("url"). Mouse. Up += new Mouse. Event. Handler(b_Mouse. Up). link. Bar. Items. Add(b). my. Xml. Save(links. Xml). }The Tool. Strip. Button control doesn't have a Context. Menu so if you want to add a context menu, you need to do some tricks. Here is my idea for solving this problem. In the designer view, I added a Context. Menu control named link. Context. Menu and added some items on this context menu. When the user right- clicks a link, then this context menu is shown at the position where the mouse is. Then, you retain the website address and the name of this link (button that sent this event). For retaining the last address and name, I used two variables: adress and name. So, when the user clicks a context menu item, you can use these variables. Mouse. Up(object sender, Mouse. Event. Args e). Tool. Strip. Button b = (Tool. Strip. Button)sender. Tool. Tip. Text. name = b. Text. if (e. Button == Mouse. Buttons. Right). link. Context. Menu. Show(Mouse. Position). }Each context menu item has a click event handler. Below is an example of opening the link in a new window: privatevoid open. In. New. Window. Tool. Strip. Menu. Item_Click(object sender, Event. Args e). WBrowser new_form = new WBrowser(). Show(). new_form. Current. Browser(). Navigate(adress). For storing History and Favorites, I used two XML files: history. Visited="1. 9. 0. Visited="1. 9. 0. Visited="1. 3. 0. Google- images< /favorit> < favoriturl="http: //www. Yahoo!< /favorit> < /favorites> For showing History and Favorites, I used a Tree. View control. Here is an example of showing history based on the site name: privatevoid show. History(). history. Tree. View. Nodes. Clear(). Xml. Document my. Xml = new Xml. Document(). File. Exists(history. Xml)). my. Xml. Load(history. Xml). Date. Time now=Date. Time. Now. if (combo. Box. 1. Text. Equals("View By Site")). Tree. View. Show. Root. Lines = true. Xml. Element el in my. Xml. Document. Element. Child. Nodes). Uri site=new Uri(el. Get. Attribute("url")). Tree. View. Nodes. Contains. Key(site. Host. To. String())). Tree. View. Nodes. Add(site. Host. To. String(). site. Host. To. String(),0,0). Tree. Node node =new Tree. Node(el. Get. Attribute("url"), 3, 3). Tool. Tip. Text = el. Get. Attribute("url") +. Last Visited: " +. Get. Attribute("last. Visited") +. "\n. Times Visited: " +. Get. Attribute("times"). Name = el. Get. Attribute("url"). Context. Menu. Strip = hist. Context. Menu. history. Tree. View. Nodes[site. Host. To. String()]. Nodes. Add(node). For adding a website to Favorites, I created a form named Add. Fovorites which will be treated as a dialog. The constructor of this class takes a string argument representing the current web address. When the user clicks the "Add to favorites" button, the Add. Favorites dialog will appear. The user can choose whether to add a favorite or a link. Strip. Button. 8_Click(object sender, Event. Args e). if (get. Current. Browser(). Url != null). Add. Favorites dlg =. new Add. Favorites(get. Current. Browser(). Url. To. String()). Dialog. Result res = dlg. Show. Dialog(). if (res == Dialog. Result. OK). {. if (dlg. File == "Favorites"). Favorit(get. Current. Browser(). Url. To. String(). dlg. fav. Name). else add. Link(get. Current. Browser(). Url. To. String(). Name). dlg. Close(). The add. Favorit() method is listed below. It is similar to the add. Link method, except it opens another XML file containing the favorite website, and it adds a Tree. Node in fav. Tree. View. privatevoid add. Favorit(String url, string name). Xml. Document my. Xml = new Xml. Document(). Xml. Element el = my. Xml. Create. Element("favorit"). Set. Attribute("url", url). Inner. Text = name. File. Exists(fav. Xml)). Xml. Element root = my. Xml. Create. Element("favorites"). Xml. Append. Child(root). Append. Child(el). Xml. Load(fav. Xml). Xml. Document. Element. Append. Child(el). Panel. Visible == true). Tree. Node node = new Tree. Node(el. Inner. Text. Index(el. Get. Attribute("url")). Index(el. Get. Attribute("url"))). Tool. Tip. Text = el. Get. Attribute("url"). Name = el. Get. Attribute("url"). Context. Menu. Strip = fav. Context. Menu. fav. Tree. View. Nodes. NET Web. Browser control - get active contextmenu. Similar Questions.
