Home Zoom using two forms
 I have a multiple forms in my project. Form1 contains a pictureBox that displays a jpeg. In Form2 I have a trackBar that I would like to control the zoom level of the image in Form1. To keep it simple I only need 2 or 3 zoom levels. I've set the pictureBox to public in the Designer view. However, when I try to reference the pictureBox in Form2 it says it doesn't exist. Below is the code I'm using to call Form2 in Form1 Form2 dataWindow = new Form2(); dataWindow.ShowDialog();  So in short the two things I need help with is: 1) Changing the properties of pictureBox1 from a separate form. 2) Creating a simple Zoom Formula.
