{
	private TextBox _maxZoomFactorTextBox;
	private GcZoom _gcZoom1 = new GcZoom();

	public GcZoomDemo()
	{
		InitializeComponent();

		_gcZoom1.Target = this;

		_maxZoomFactorTextBox.TextChanged += maxZoomFactorTextBox_TextChanged;
	}

	void maxZoomFactorTextBox_TextChanged(object sender, EventArgs e)
	{
		string value = _maxZoomFactorTextBox.Text.Trim();

		try
		{
			float maxFactor = (float)Convert.ToDouble(value);
			_gcZoom1.MaxZoomFactor = maxFactor;
		}
		catch
		{
			_gcZoom1.MaxZoomFactor = 2f;
		}
	}

	private void InitializeComponent()
	{
		_maxZoomFactorTextBox = new TextBox();
		_maxZoomFactorTextBox.Location = new Point(160, 80);
		this.Controls.Add(_maxZoomFactorTextBox);
	}
}

Public Class GcZoomDemo
	Inherits Form
	Private _maxZoomFactorTextBox As TextBox
	Private _gcZoom1 As New GcZoom()

	Public Sub New()

	End Sub

	Private Sub maxZoomFactorTextBox_TextChanged(sender As Object, e As EventArgs)
 		Dim value As String = _maxZoomFactorTextBox.Text.Trim()

		Try
			Dim maxFactor As Single = CSng(Convert.ToDouble(value))
			_gcZoom1.MaxZoomFactor = maxFactor
		Catch
	 		_gcZoom1.MaxZoomFactor = 2.0F
		End Try
	End Sub

	Private Sub InitializeComponent()
