Ok much easier to see now, and didn't see the question before... can you post what your text box has as properties from the designer?
Form.vb [Design] -- visual designer
Form.vb -- actual code
Form.Designer.vb <-- That one (it will be a child-tree of Form.vb)... You may have to click the button to 'see all files'
It will look something like attached (note: don't change thins in here unless you know what it is doing)
