Getting the Associated Zoom

You can get the associated C1Zoom by a specific form programmatically by using the GetC1Zoom static method of C1ApplicationZoom class. It always works even if the current application has a C1ApplicationZoom instance or not.

[C#]

using C1.Win.TouchToolKit;

private void button1_Click(object sender, EventArgs e)
{
  Form2 subForm = new Form2();
  C1Zoom c1Zoom = C1ApplicationZoom.GetC1Zoom(subForm);
  if (c1Zoom == null)
  {
    MessageBox.Show("There is no C1Zoom.");
  }
  else
  {
    MessageBox.Show("There is a C1Zoom.");
    c1Zoom.AboutBox();
  }
  subForm.Show();
}

[Visual Basic]

Imports C1.Win.TouchToolKit

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
  Dim subForm As New Form2()
  Dim c1Zoom As C1Zoom = C1ApplicationZoom.GetC1Zoom(subForm)
  If c1Zoom Is Nothing Then
    MessageBox.Show("There is no C1Zoom.")
  Else
    MessageBox.Show("There is a C1Zoom.")
    c1Zoom.AboutBox()
  End If
  subForm.Show()
End Sub
