try
{
    Quaternion tempQuaternion = new Quaternion(axis, angle);
    QuaternionWText.Text = tempQuaternion.W.ToString();
    QuaternionXText.Text = tempQuaternion.X.ToString();
    QuaternionYText.Text = tempQuaternion.Y.ToString();
    QuaternionZText.Text = tempQuaternion.Z.ToString();
}
catch
{
    MessageBox.Show("Set non-null values for the axis Vector3D.");
}

'convert to quaternion and update display
Try
    Dim tempQuaternion As New Quaternion(axis, angle)
    QuaternionWText.Text = tempQuaternion.W.ToString()
    QuaternionXText.Text = tempQuaternion.X.ToString()
    QuaternionYText.Text = tempQuaternion.Y.ToString()
    QuaternionZText.Text = tempQuaternion.Z.ToString()
Catch
    MessageBox.Show("Set non-null values for the axis Vector3D.")
End Try
