When you are ready, continue on..

Requirements

• Minimal knowledge on csharp language
• Microsoft .NET framework installed
• Development IDE ( SharpDevelop ) installed
• Completed the walkthrough in previous articles

I wrote these codes with .NET framework 2.0 installed on my machine.
However it should work on .NET framework 1.0+ (not tested)

Ok.. let’s begin,

• Startup your SharpDevelop IDE
• Create New Window Application project, let’s call it PMozilla (Portable Mozilla)
• You should have Program.ch and a few other created automatically
• Add new class AppStarter.ch
• Copy and paste the following code and save it
  File: AppStarter.ch

using System;
using System.Diagnostics;
using System.ComponentModel;
 
namespace PMozilla
{
 ///
 /// Description of AppStarter
 ///
 public class AppStarter
 {
  Process proc = null;
  public AppStarter()
  {
   proc = new Process();
  }
 
  public void startFirefox()
  {
   try {
    proc.StartInfo.FileName = "./Firefox/firefox.exe";
    proc.StartInfo.Arguments = "-profile ./_profiles/firefox";
    proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
    proc.StartInfo.CreateNoWindow = true;
    proc.Start();
   }
   catch (Win32Exception e)
   {
    e.GetBaseException();
   }
  }
  public void startThunderbird()
  {
   try {
    proc.StartInfo.FileName = "./Thunderbird/thunderbird.exe";
    proc.StartInfo.Arguments = "-profile ./_profiles/thunderbird";
    proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
    proc.StartInfo.CreateNoWindow = true;
    proc.Start();
   }
   catch (Win32Exception e)
   {
    e.GetBaseException();
   }
  }
 }
}

• Replace Program.ch with the following codes
  File: Program.ch

using System;
using System.Windows.Forms;
 
namespace PMozilla
{
 ///
 /// Class with program entry point.
 ///
 internal sealed class Program
 {
  ///
  /// Program entry point.
  ///
  [STAThread]
  private static void Main(string[] args)
  {
   AppStarter ast = new AppStarter();
   ast.startFirefox();
  }
 }
}

• Save project
• Build project, make sure there’s no error
• Now go to your project debug Directory (ie. PMozilla\bin\Debug)
• You should see PMozilla.exe
• Copy this file and paste it in your portable firefox directory. Put it outside directory containing firefox.exe
• Rename PMozilla.exe to Firefox.exe
• Now double click on a new Firefox.exe
• A portable Firefox should start.

Create another one for Thunderbird

• Go back to your IDE and open the same project if it’s closed
• Modify Program.ch
• Replace ast.startFirefox(); (line 18) to ast.startThunderbird();
• Now, Save project
• Build project, make sure there’s no error
• Now go to your project debug Directory (ie. PMozilla\bin\Debug)
• You should see PMozilla.exe
• Copy this file and paste it in your portable thunderbird directory. Put it outside directory containing thunderbird.exe
• Rename PMozilla.exe to Thunderbird.exe
• Now double click on a new Thunderbird.exe
• A portable Thunderbird should start.
