    ListBox Item Objects: what is displayed?

    I'm going to be using a ListBox in my managed C++ application, and have a
    question. Why are the Items you Add to a ListBox in the form of generic
    Object*'s? I believe a ListBox displays a table of selectable options via
    multiple lines (or columns) of TEXT, so why doesn't Add merely take a
    String* ? How does it know what to display (i.e., the text of each Item
    listing) with a generic Object* (or do all Object's have some Text property
    ListBox knows to display to represent it)? Put more to the point, if I Add
    an Item which ISN'T a String*, what does the ListBox display?

    Thanks in advance! : )

      You should look up DisplayMember and ValueMember, which are listbox
      properties. I have never used it myself but you can use that to control what
      is displayed in the listbox.
