GUI Programming With Multiple Forms 2/4
The initial form has a main() method
Assuming: Form1 is the initial form:
public class Form1 : System.Windows.Forms.Form
{ ...
[STAThread]
static void Main()
{
Application.Run(new Form1());
}
...
}

GUI Programming With Multiple Forms 3/4
Create an instance of other forms before displaying it or working with any
controls or properties
public class Form1 : System.Windows.Forms.Form {
Form2 form2 = new Form2();
...
form2.setSomeProperty(value);
Value v = form2.getSomeProperty();
...
form2.show();
...
}

GUI Programming With Multiple Forms 4/4
Pass the reference of your form to any code that needs access to your form
Assuming: Form2 needs to set some property in Form1:
public class Form2 : System.Windows.Forms.Form {
private Form1 form1=null;
public void setForm1(Form1 form) {
this.form1= form;
}
/*this method is called by Form1 like this:
private void goToF2Button_Click(object sender, System.EventArgs e) {
f2.setValueOnForm2(this.textBox1.Text);
f2.setForm1(this);
f2.Show();
}*/
private void goToF1button_Click(...) {
if (form1 == null) {Error(); return;}
form1.setPropertyOnForm(value);
form1.Show();
}
}
