How to get default browser icon in C #?

Question

I have a button that says "Open in browser." I would like to rename it to “Open” and show the default browser icon next to it.

If the default browser is firefox, then I want the Firefox icon in my button. If the default browser is chrome, then I want a chrome icon.

How can I get the default browser icon?

If it is different for each version of windows, I need window version 7.

I changed the code a bit and here is my version.

using System; using Microsoft.Win32; using System.Drawing; namespace Namespace { public static class DefaultSystemBrowser { private static bool initialized = false; private static string path = null; public static string Path { get { CheckForErrors(); return path; } } public static Icon Icon { get { CheckForErrors(); return Icon.ExtractAssociatedIcon( path ); } } public static Bitmap Bitmap { get { CheckForErrors(); return Icon.ExtractAssociatedIcon( path ).ToBitmap(); } } private static void CheckForErrors() { if ( !initialized ) throw new InvalidOperationException( "You can't use DefaultSystemBrowser class before you call Determine()." ); if ( ErrorMessage != null ) throw new InvalidOperationException( "You can't use DefaultSystemBrowser class if call to Determine() resulted in error." ); } /// <summary> /// Null if no error occured, error description otherwise. /// </summary> public static string ErrorMessage { get; private set; } /// <summary> /// Finds out all information about current default browser. You can call this method every time you want to find out default browser. /// </summary> public static void Determine() { path = String.Empty; initialized = true; RegistryKey regKey = null; ErrorMessage = null; try { //set the registry key we want to open regKey = Registry.ClassesRoot.OpenSubKey( "HTTP\\shell\\open\\command", false ); //get rid of the enclosing quotes path = regKey.GetValue( null ).ToString().ToLower().Replace( "" + (char) 34, "" ); //check to see if the value ends with .exe (this way we can remove any command line arguments) if ( !path.EndsWith( "exe" ) ) //get rid of all command line arguments (anything after the .exe must go) path = path.Substring( 0, path.LastIndexOf( ".exe" ) + 4 ); initialized = true; } catch ( Exception ex ) { ErrorMessage = string.Format( "ERROR: An exception of type: {0} occurred in method: {1} in the following module: {2}", ex.GetType(), ex.TargetSite, typeof( DefaultSystemBrowser ) ); } finally { //check and see if the key is still open, if so //then close it if ( regKey != null ) regKey.Close(); } } } } 

This is how I use the code:

  DefaultSystemBrowser.Determine(); if ( DefaultSystemBrowser.ErrorMessage == null ) { btnOpenInBrowser.Image = DefaultSystemBrowser.Bitmap; } else { btnOpenInBrowser.Image = Properties.Resources.firefox_24_noshadow; }

Insert an empty htm or html file into your application (or create one)

Then call the Icon.ExtractAssociatedIcon method in this file.

It will return the default browser icon.
