showing a form twice

godzooky

i have a stupid problem. i show my form, close it and try to show it again, but i get an error saying i'm trying to access a disposed object. how can i prevent that? i must be missing something obvious. thanks.

You're trying to reuse a disposed reference. This occurs because you have created an object which has subsequently been disposed. What you need to do is something like the following:

private void CreateMyForm()
{
  using (MyForm myForm = new MyForm()) 
  {
    myForm.Show();
  }
}

Then call CreateMyForm whenever you want to create an instance of this form.

You can use GC::KeepAlive(yourForm)

I've had a similar problem. My solution was to catch the FormClosing event, and when e.CloseReason == CloseReason.UserClosing, set e.Cancel to true and Hide the form.
