You all know AutoIt MsgBox maker. How about C# MsgBox maker. Didn't know you can do one? If not, here's an example:

Well, let's get started.

Code:

using System;
  using System.Drawing;
  using System.Collections;
  using System.ComponentModel;
  using System.Windows.Forms;
  using System.Data;

  public class MainForm : System.Windows.Forms.Form
  {
    private System.ComponentModel.Container components;

    public MainForm()
    {
      InitializeComponent();
      BackColor = Color.Tomato;
      Opacity = 0.5d;
      Text = "[You must be registered and logged in to see this link.]
      Cursor = Cursors.WaitCursor;
      this.Paint += new System.Windows.Forms.PaintEventHandler(this.Form1_Paint);
    }

    protected override void Dispose( bool disposing )
    {
      if( disposing )
      {
        if (components != null)
        {
          components.Dispose();
        }
      }
      base.Dispose( disposing );
    }

    private void InitializeComponent()
    {
      this.AutoScaleBaseSize = new System.Drawing.Size(5, 13);
      this.ClientSize = new System.Drawing.Size(292, 273);
      this.Text = "Form1";
    }
    [STAThread]
    static void Main()
    {
      Application.Run(new MainForm());
    }

    private void Form1_Paint(object sender, System.Windows.Forms.PaintEventArgs e)
    {
      Graphics g = e.Graphics;
      g.DrawString("[You must be registered and logged in to see this link.]
        new Font("Times New Roman", 20),
        new SolidBrush(Color.Black), 40, 10);
    }
  }

Simple, right?

Very, very simple.
