1,2,3 i already know. 4 I'm already try. but it only can take text already fix in textbox only. so when use key in textbox, it will not bring it to next page.

This is a example which demonstrate how to change text of label1 on form2 from form1

Form2 f = new Form2();
f.label1.Text = textBox1.Text;
this.Hide();
f.Show();

before writing this code you to change label1 from private to public to do that
1. first click on "show all files" on solution explorer
2.Open code window of form2.designer.cs and you find

private  System.Windows.Forms.Label label1;

to

public  System.Windows.Forms.Label label1;

similarly you can able to pass any variable to other form but variable must declare as public to get access

I hope it will help you
