Open new IE after closed ERROR!

P: n/a
Hi All, I am trying to open a new instance of IE at the start of my C# application.

When user press Start Recording... My applicaiton will close that specific instance of IE and Open a fresh IE, but if that instance is closed manually, then the App must still be able to open a new fresh IE...

It give me the following erro message:

An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in ieObjTest.exe

Here is my Code.

using SHDocVw;
using System.Diagnostics;

InternetExplorer browser;
protected Process[] processes;
protected Process browserProcess;

public frmSiteAlert()

// detect if IE is already running ?
processes = Process.GetProcessesByName("IEXPLORE");

if(processes.Length >= 1)
MessageBox.Show(processes.Length + " Running Copies of internet Explorer has been Detected... ");

// Get the Screen resolution
this.Size = new Size(getScreenWidth(), getScreenHeight()* 30/100);
this.MinimumSize = new Size(200, getScreenHeight()* 30/100);
// Display the form in the top let corner of the screen.
this.StartPosition = FormStartPosition.Manual;

static void Main()
Application.Run(new frmSiteAlert());

public void openBrowser()
browser = new InternetExplorer();
browserProcess = Process.GetCurrentProcess();
if (browser != null)
browser.Height = getScreenHeight() *70/100-30;
browser.Width = this.Width;
browser.Top = getScreenHeight()*30/100;
//opened = true;
browser.Visible = true;
object obj = null;
browser.Navigate("about:blank", ref obj, ref obj, ref obj, ref obj);

// When Start Recording is pressedd
private void miStartRecording_Click(object sender, System.EventArgs e)

/// HERE THE BROGRAM BREAKS !!!!!!!!!!!!!!!

private int getScreenWidth()
int screenWidth = Screen.PrimaryScreen.Bounds.Width;
return screenWidth;

private int getScreenHeight()
int screenHeight = Screen.PrimaryScreen.Bounds.Height;
return screenHeight;
