Accessing Controls on Another Winform

I'm new with C#, and have a question about Winforms. If I have 2 winforms, let's say Form1 which contains 2 CheckBox controls and a Button. Upon pressing the button I call Form1.hide() and show Form2. Form2 needs to check Form1's checkboxes to see which are select and then print to the screen "Checkbox 1 is selected" (for example). How can I access the Checkbox controls on Form1 when it is hidden (therefore still retaining the values I assume). Also if I have a back button on Form2, how can I show Form1 again. Currently to show Form2 I have this code: if (nextForm == null) nextForm = new Form2(); nextForm.Refresh(); nextForm.Show(); this.Hide(); I define nextForm as: private Form2 nextForm; Thanks in advance for any help.

Don't think forms as "forms" but objects. They are just classes. So your question is "how can two objects communicate". Somehow the other objects needs to have reference to the other. You can, for example, pass it to the constructor nextForm = new Form2(this);
