In previous article we learned How to Open Firefox Browser using selenium 'WebDriver'.

For opening or launching Internet Explorer (IE) is different from Open FireFox. In that we need one extra EXE file named 'IEDriverServer.exe' file and also set 'IE' Options object to give Startup URL.

If you Do not have 'IEDriverServer.exe' file file at that time Code gives us an error like :

The IEDriverServer.exe file does not exist in the current directory or in a directory on the PATH environment variable.

But basically it is very simple.

Here are steps to learn How to Open IE Browser :


STEP 1 : First create new 'WebSite' after creating new 'WebSite' add new page. On this previous article your learn this.

STEP 2 : Now, you need special Executable (EXE) file named "IEDriverServer.exe". You can download this file from this URL :
http://selenium-release.storage.googleapis.com/index.html. You can choose latest version folder on this link. Or you can also get this file from our project zip file, In our project we have both 32 and 64 bit zip file. You can get that file from zip file.

STEP 3 : After downloading file, Add new folder in your website or project named it 'EXEFiles' and copy your downloaded file 'IEDriverServer.exe' in this folder.

STEP 4 :  Open your new page code file like 'Default.aspx.cs' file. Import selenium 'namespaces' and write following code on 'Open Internet Explorer Browser' button click event.

Code File :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Selenium;
using OpenQA;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void btnOpenIEBrowser_Click(object sender, EventArgs e)
    {
        string STR_IE_DRIVER = Server.MapPath("EXEFiles"); //Set Path for EXE file

        var objIEOptions = new OpenQA.Selenium.IE.InternetExplorerOptions() // Set Options
        {
            InitialBrowserUrl = "www.google.com",
            IntroduceInstabilityByIgnoringProtectedModeSettings = true
        };

        //Create object for open IE
        OpenQA.Selenium.IE.InternetExplorerDriver objFF = new OpenQA.Selenium.IE.InternetExplorerDriver(STR_IE_DRIVER, objIEOptions);
    }
}

Explanation : In this code you can see that First we set path of 'IEDriverServer.exe' file, in which folder we save this file. After that, we create object of 'InternetExplorerOptions' class and set properties like 'InitialBrowserUrl' and 'IntroduceInstabilityByIgnoringProtectedModeSettings'.

This 'InitialBrowserUrl'  property use for By default when IE open this URL is open in IE. After that, we create object of 'InternetExplorerDriver' class to open IE. You can see that in constructor of 'InternetExplorerDriver' class we supply 'IE_DRIVER' Path and 'IE OPTION' object.

STEP 5 : Run the website. After Default page is appeared in browser, this website may run in any browser. You click on 'Open Internet Explorer Browser' button. It will Open Internet Explorer Successfully.
