Please learn to cross-post properly, by including all newsgroups in

Setting e.Cancel to true in the FormClosing-event should do the trick.

You need something else, you need a flag to know when the form is closing
from the code or is the user trying to close it.

bool canClose = false;

void form_Closing(.. .. )
{
e.Cancel = !canClose;
}

so if you want to close the form you do:

canClose =true;
Close();
