Passing values between two classes RRS feed

  • 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.

  • 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.

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