Hiding a form without calling FormClosing method

Question

I have two forms and I have linked it up so that when the second form is closed the first is closed too (using the FormClosing method).

The problem with this is that when I wish to hide the second form it automatically closes the first. Is there a way in which a form can be hidden without actually calling the FormClosing method?

The FormClosing method still seems to be called when "Visible = false" and "Hide()" are used.

Thanks.

Answer 1

I changed my program so that it is started as below:

        MainForm mainForm = new MainForm();
        mainForm.Show();
        Application.Run();

Instead of:

        Application.Run(new MainForm());

In each of the forms I have added a FormClosing event which checks to see if the user has opted to close the application. If this is the case a prompt is shown to the user to ask for their confirmation:

    private void ImageSelect_FormClosing(object sender, FormClosingEventArgs e)
    {
        if (e.CloseReason == CloseReason.UserClosing)
        {
            if (DialogResult.No == MessageBox.Show("Are you sure you wish to exit?", "Exit Confirmation", MessageBoxButtons.YesNo))
                e.Cancel = true;
            else { Application.Exit(); }
        }
    }

The application now can be closed from any form in the application.

Answer 2

call Hide() on the form or Visible=false, but onsider in this case the the form remains in memory and all allocated resources by that form remain in the memory.

If this is a problem for you, I would suggest to revise your architecture.

Answer 3

You want to use form.Hide().

This just conceals the form from the user without actually closing it.

Answer 4

this.Hide();

or

this.Visible = false;

Answer 5

If you use WinForms forms the method Hide() should be the one which you are looking for.
