This is the example of a Client Chooser, you can do it better, add more option o whatever you want.

This picture shows 2 clients, 1 open and logged in and other only open.

You can do a class player with all its attributes, to do it more simple. If you have some problems interpreting the code comment, and maybe you need to eliminate some things . So all do you need is the Object c, if you want to do a healer you can pass the object to the constructor of a FormHealer for example and use it. Now you can work easily in XP and seven. Your main form will look like this.

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;

using MXbotALFA.Objetos;

using MXbotALFA.Util;

namespace MXbotALFA.Forms

{

	public partial class MainMx : Form

	{

		private Cliente c;

		public MainMx(Cliente c)

		{

			this.c = c;

			InitializeComponent();

		}

		private void MainMx_Load(object sender, EventArgs e)

		{

			this.Text = "MXbot ~ "+c.getNombre;

		}

	}

}
