Passing values between two classes

Question

Hi I am currently working on a project that requires me to pass a DateTime value from MainForm to Appointments.

I have a combo box which I want to pass the date from that to another form to put into a textbox.

Answer 1

There are two requirements for one object (A) to set the value of another one (B):

1. The value or a proper setter function in B must be public.

2. The instance of A needs a reference to teh isntance of B

So the big question is: Where are appointements stored? Are those classes created by the main form? Is there some form of application wide storage that all Forms share*? Are both forms, if so when and how is Appointments created?

*WinForms lacks proper support for application wide variables that all forms share, but you can get something close by using static variables.

 // In Class1 :
public  class Class1
    {
       public static string TheName = "";
    }
}

// In Form1 :

  private void button1_Click(object sender, EventArgs e)
        {
            Class1.TheName = this.textBox1.Text;
            Form Frm = new Form2();
            Frm.Show();
        }

// In Form2 :
 private void Form2_Load(object sender, EventArgs e)
        {
            this.textBox1.Text = Class1.TheName;
        }
