Hi all,

I'm fairly new to C# and have run into a problem. I have one form mainForm which creates a new form optionsForm when a button is clicked.

private void button_Click(object sender, EventArgs e)
Options optionsForm = new Options(this);
DialogResult result = optionsForm.ShowDialog(this);

In the optionsForm, I've tried to pass mainForm by reference so I could access its objects.

private form_VisionSystem mainForm = null;
public Options(Form callingForm)
mainForm = callingForm as form_VisionSystem;


I would like to access an object from mainForm and that object's methods from optionsForm. Is this possible, and if so how could I go about achieving this.

Any help would be greatly appreciated.
