Question

I am stuck in a deep problem right now. Plz help me with this….

I created a FORM call it form1. It contains a textbox T1. I started it running…
inside form1 there is a thread running which does some process P which is a member of a different CLASS call it class2.
To run the process P, I need a value from textbox T1. HOW DO I DO THAT?

Let me tell you, what I tried already.
I created instance of form1 in class2, and then tried to read textbox (T1) value. But that was empty, I figured out that reason…. rest, I tried with the property… Again failed…

PLZ help me with this. I am stuck since hours….

    Assuming Class1 is the class which does some process in thread. Create the property which corresponds to type of your main form. In this case, its called Form1. 



     class Class1
        {
    //his is the property
            public Form1 MyMainForm { get; set; }

            public  void    ShowText()
            {

//here the control is accesses 
//((TextBox)MyMainForm.Controls.Find("textBox1",true)[0])
                MessageBox.Show(((TextBox)MyMainForm.Controls.Find("textBox1",true)[0]).Text);
            }
        }

    im assuming ShowText() method is called on new thread, when button is clicked.

     private void button1_Click(object sender, EventArgs e)
            {
    //craete instance of class1
                Class1 c = new Class1();
    //set the  property            
    c.MyMainForm = this;
    //start the method is new thread
                ThreadStart ts=new ThreadStart(c.ShowText);
                Thread t=new Thread(ts);
                t.Start();
            }
