how to avoid create child form twice

[pei_world]

I have a parent form as container, and also have a child form.
suitation is that, when I click a button from parent form, childform created
and show,
I want to know how to do something like this:
first time create the child form and show it, on the second time, just show
it again without re-creating it.
thanks
