Cannot transfer data between different Forms

Hello guys... I am new to this forum and new to DotNet too..I am on C# track and currently facing the problem described below.I am practicing on VS2002 and 1.1 framework and my OS is windows XP. As i am new to this forum, i dont know this query has been asked by anyone before..if yes then please send me the link to the page..ThankYou Problem: I am having two Forms in my application(Form1 and Form2).Form1 is startup form.Form1 contains a richtextbox and a button.This button opens Form2.Form2 contains a datetimepicker and a button. Now what i want to do is, when i click the button of Form2, i want the richtextbox to show the date (datetimepicker.text). i dont know how to pass data from 1 form to another..please help me as soon as possible.. Thankyou; Logically _Yours;

there can be many solutions to this.two of them are

sol1. Create a data class wch contains a static property to hold the datepicker's value. Set the property in Form2 and get its value in Form1.

sol2.
create a public function in the Form1 wch accepts instance of Form2

public void ShowDate(Form2 form2){

richTextBox1.Text = form2.DATE;// Date is a public property in Form2 wch return datepicker's
value
}

Pass the parent form in the constructor of the Form2
// in Form1
Form f = new Form2(this);

// In Form2

private Form1 parentForm = null;

public Form2(Form1 parent){

InitializeComponent();
parentForm = parent;
}

From Form2 pass instance of Form2 in public function created in the Form1.

parentForm.ShowDate(this);

then u can access all the control/properties of Form2 in Form1.

confuse?
