>In a search form, I have several HTML controls that I would like to align. By default, the content of a listbox justifies the length of the listbox control. The same applies for the INPUT control. Is there a style I can apply in order to force a fixed length?

Couldn't you use a style that incorporates the use of a non-proporational font like Courier New and then ensure the length is set to be as wide as the largest number of characters you use?
