    menus interaction

    Hi:

    I created 2 menus named: Form1, Form2 in the same solution,respectively.
    so I created a reference of Form2 and a button in Form1.
    Form2 myForm = new Form2();

    Now, the button event is myForm.Show();

    When I ran it, click the button I got Form2, so I closed the Form2, but the problem appeared if I clicked button again, it gave me such message:
    can't access a disposed object named "Form2",
    Object name:"Form2.ShowDialog"

    But if I changed to:
    myForm.ShowDialog, then no problem

    what happened??

    Thank you

    My guess is that closing Form2 disposes ( destroys ) the form. So you might need to create a new Form2 every time.

    She was so Blonde, she spent 20 minutes looking at the orange juice can because it said "Concentrate."

    When in doubt, read the FAQ.
    Then ask a smart question.

    My guess ...

    >> so I closed the Form2

    It sounds like you closed the form manually then clicked a button that references something in that form you just closed.

    Don't close that form next time, see what happens & let us know

    Ok, things are like that:
    I click the button on Form1 to pop up Form2,
    there is a reference of Form2:
    Form myForm2 = new Form2();
    inside the button event:
    myForm2.Show();
    when I ran it:
    Form2 appeared:
    there was a close button on the Form2's right top corner, so i closed, but when I clicked that button again, then I got that kind of error, why I can't click that "X" button:

    but after I changed to myForm2.ShowDialog(). then no problem.
    Strange..

    and what is the command if I control the Form2 by Form1, let's say when I click the button on Form1, then one label is created on Form2.
    I am quite newbie on C#
