1. //for functions from another forms
   Main_Form main_form = this.Owner as Main_Form;
   main_form.FUNCTION_FROM_MAIN_FORM
   //for data from another forms
   Main_From.VAR_From_Main_Form -->all VARs should be public static
2. You completely fucked my program by mixing up which form was receiving the value. I had to start over from scratch. Thanks.
3. you just passed username what if based on username and pasword it retrieves rest of information like name etc in other form textboxes
4. Am I the only one that thinks that the example works in the opposite way that he says it should work? at 2:09, he said whatever value he entered in Form2 will pop up in Form 1 after clicking the button; however, when he clicked, it sends the information from Form 1 to Form 2 instead.  This got me confused at first because I couldn't understand why he was declaring a variable in the Form 2 method that would be accepting the  text rather than sending the text.
