yes

a explanation: When I first start my Windows.Forms application, I can close it by clicking the "X" in the upper right. After running for a while, this button no longer works. it is a bug (at least it seems like) then I added a separate button, and call the close method on the window directly, and I would want to disabled the "X". Paola

it is possible to render disabled (o not visible) the button of closing (x) on the form caption, leaving the title bar visible ?? Thanks, Paola
