Error calling a form that has been Closed with this.Close();

[Fuzz13]

I have a program that uses a custom message box. There is only the OK button on it which I originally coded with:

this.close();

but then if I ever tried to load the message box again it said "can not access disposed form".

I then set it instead to just hide the form when the ok button was clicked, which works, but I am not sure if it is running unnecessary resources?

Can anyone make a suggestion on whether I'll be ok having the form hidden (the form contains one small graphic and 3 labels if that makes a difference) or is there a way to close that form but still be able to call it again from the parent form?

Thanks.

If you close() a form, its done. You would have to start all over.
Hide()'ing the form is a better method if it gets used regularly. If the form is hardly ever used, it MIGHT be better to close/dispose/start over with a new one when you need it.

"If you close() a form, its done."
I think that says it most perfectly. I went ahead and used the hide method. Thank you for explaining that for me.
