Assuming you mean a standard  textbox in a userform, it can be pretty
much be set up any way you want it to, so some examples would be:

TextBox1.MultiLine = True
TextBox1.WordWrap = True
TextBox1.MaxLength = 360 'i.e. maximum number of characters
TextBox1.BackColor = RGB(255, 255, 255) 'background color
TextBox1.ForeColor = RGB(0, 0, 0) 'font color

etc.

If that's not what you mean, please clarify. I didn't understand
what you meant by "and not keep running  box" . . . ?
