This is a simple web browser I made in C# using visual studios 2008

First off start a new "Windows Forms Application" in visual studio.

The controls you'll need are:

Control-------Name of control------Text Displayed

ToolStrip         toolStrip                 (none)

-button1            backButton             Back
-button2             forwardButton             Forward
-separator         separator                 (none)
-label             urlLabel                 URL:
-textBox             urlTextBox             *Starting Url* http://www.google.com/
-button3             goButton                 GO

ToolStrip2         statusStrip             (none)
-label1             doneLabel                 Done
-label2             openingLabel             Opening
-progressBar         progressBar             (none)

WebBrowser         webBrowser             (none)

ToolStrip

To add tools to your tool strip, if you don't know how, you simple click the drop down arrow to right of the repeat image on the toolstrip, and select the tool you want.

Go into the urlTextBox properties and set the Width of the textbox to 400.

If you have an image for you backButton, forwardButton, or goButton then go a head and use it, but if you don't just go in to the DisplayStyle Property and select Text. This should display what typed int the Text property.

Set the Enabled Property to false for both the backButton and the forwardButton.

This is what your toolStip Should look like:

(I Changed the Background color of the toolStrip from its defualt color for this tutorial so that its easyer to see)

StatusStrip

All you need to do right now is change the Alignment Property of the progressBar to Right, and set the Visible

Property of the doneLabel, openingLabel, and progressBar to False.

This is what your statusStip Should look like:

(I Changed the Background color of the statusStrip from its defualt color for this tutorial so that its easyer to see)

WebBrowser

The webBrowser's Dock Property should have been Fill by default but if its not then change it to Fill.

The Code

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;

namespace WebBrowser

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

// Declared Variables

private string[] SiteMemoryArray = new string[100];

private int count = 0;

// Page Load

private void Form1_Load(object sender, EventArgs e)

{

webBrowser.Navigate("http://www.google.com/");// Goes To A Preset Site At Run Time

SiteMemoryArray[count] = urlTextBox.Text;// Saves URL To Memory

}



// Code For The ToolStrip 

// URL TextBox 

private void urlTextBox_Click(object sender, EventArgs e)

{

urlTextBox.SelectAll();// Selects All The Text In The urlTexBox

}

// GO Button

private void goButton_Click(object sender, EventArgs e)

{

webBrowser.Navigate(urlTextBox.Text);// Navigates To The Site Typed In The urlTextBox

}



// Back Button

private void backButton_Click(object sender, EventArgs e)

{

if (count > 0)// Checks To Make Sure The Count Variable Is More Then 0

{

count = count - 1;// Subtracts 1 From Count Variable 

urlTextBox.Text = SiteMemoryArray[count];// Replace The Text In The urlTextBox With
                                         // The Last URl

webBrowser.Navigate(urlTextBox.Text);// Navigates To The Site Typed In The urlTextBox

forwardButton.Enabled = true;// Enables The forwarButton

}

}

// Forward Button

private void forwardButton_Click(object sender, EventArgs e)

{

if (count < 100)// Checks To Make Sure The Count Variable Is Less Then 100

{

count = count + 1;// Adds 1 To Count Variable

urlTextBox.Text = SiteMemoryArray[count];// Replace The Text In The urlTextBox With
                                         // The Next URl

webBrowser.Navigate(urlTextBox.Text);// Navigates To The Site Typed In The urlTextBox

backButton.Enabled = true;// Enables The backButton

count = count + 1;// Adds 1 To Count Variable 

// Checks To See If The Next Variable In The SiteMemoryArray Is Null
if (SiteMemoryArray[count] == null)
{

forwardButton.Enabled = false;// Disables The forwarButton

}

count = count - 1;Subtracts 1 From Count Variable 

}

}

// Web Browser

// Before Navigating

private void webBrowser_Navigating(object sender, WebBrowserNavigatingEventArgs e)

{

doneLabel.Visible = false;// Sets The Visible Property of The donLabel To False

progressBar.Step = 10;// Sets The Step Value The progressBar to 10

progressBar.PerformStep();// Preforms The Step Rasing The progressBar Value From 0 to 10

}

// After Navigating

private void webBrowser_Navigated(object sender, WebBrowserNavigatedEventArgs e)

{

progressBar.Step = 80;// Sets The Step Value The progressBar to 80

progressBar.PerformStep();// Preforms The Step Rasing The progressBar Value From 10 to 90

urlTextBox.Text = webBrowser.Url.ToString();// Replace The Text In The urlTextBox
                                            // With The URl Currently Loading

openingLabel.Text = "Openning: " + urlTextBox.Text;// Displays The Message Opening: And
                                                   // The Current URL 

openingLabel.Visible = true;// Sets The Visible Property of The openingLabel To True

}

// After The Site Has Finished Loading

private void webBrowser_DocumentCompleted(object sender,
    WebBrowserDocumentCompletedEventArgs e)

{

progressBar.Step = 10;// Sets The Step Value The progressBar to 10

progressBar.PerformStep();// Preforms The Step Rasing The progressBar Value From 90 to 100

progressBar.Visible = false;// Sets The Visible Property of The progressBar To False

openingLabel.Visible = false;// Sets The Visible Property of The openingLabel To False

doneLabel.Visible = true;// Sets The Visible Property of The doneLabel To True

// Checks To Make Sure The Same URL Is Not Being Enter Twice In A Row
if (SiteMemoryArray[count].ToString() != webBrowser.Url.ToString())   
{

count = count + 1;// Adds 1 To Count Variable

SiteMemoryArray[count] = urlTextBox.Text;// Saves The Site URL To Memory

}

if (count > 0)// Checks To See If The Count Is More Then 0
{
  backButton.Enabled = true;// Enables The backButton
}
else
{
  backButton.Enabled = false;// Disables The backButton
}
}
}
