Right, but I'm saying, this will not change. It's not possible to extend a control beyond the window. It makes even less sense to resize the window to match text inside the control.
I think you might actually be talking about HEIGHT, not WIDTH. Can you clarify this? "Wider" is a qualification of width, not height. If you want the box to be TALLER, you should say so. This is already possible with the automatic editbox sizing, or multiline, as suggested above.
Well I go by length and width but yes I am refereing to hight of the box,also I already tried that and it did not seem to work I clicked on Tools options display and lines and it was already set to auto but when I tried a test by typing in a long sentence the hight of the box did not change, the sentence simply went passed the point of being seen.
