SUMMARY
=======

The documentation for the SortOrder Property of a ListView control states that
you can "sort from the beginning of the alphabet (A-Z), the earliest date, or
the lowest number." This is incorrect. All sorting is done only on the textual
representation of the items being sorted. This means, for example, that the
number "11000" will be sorted before the number "2000" if a sort is done in
ascending order. This can also affect the sorting of dates, depending on the
format of the date in the text property of the ListItem object.

MORE INFORMATION
================

This sorting functionality is provided by the Comctl32.dll file that ships with
all 32-bit Windows operating systems. Comctl32.ocx wraps this .dll file to
provide Windows 95-style common controls to Visual Basic programmers. If a
series of documents is created and sorted in Explorer, it will show the same
behavior noted in this article and demonstrated in the Step To Reproduce sample
below. When in ascending order, numbers will be sorted before alphabetic
characters, and A will be sorted before Z. Special characters such as accents,
umlauts, tildes, and carets are sorted immediately after the character preceding
them, without the corresponding special character. These rules are reversed when
sorting is done in descending order.

Steps To Reproduce Behavior:
----------------------------

1. Start Visual Basic 4.0, 32-bit version. Form1 is created by default.

2. Add a single ListView control to the form.

3. Add this code to the form:

         Private Sub Form_Click()
             ListView1.SortOrder = 0
             ListView1.Sorted = True
             MsgBox "Sorted in ascending order"
         End Sub

         Private Sub Form_Load()
             Dim i As ListItem

             Set i = ListView1.ListItems.Add(, , "2000")
             Set i = ListView1.ListItems.Add(, , "11000")
         End Sub

4. Press F5 or select Start from the Run menu to run the application. Click once
   on the form and dismiss the "Sorted in ascending order message box". Observe
   that the number "11000" has been sorted before the number "2000".

Microsoft has confirmed this to be a documentation error in the products
mentioned at the beginning of this article. This error has been corrected in the
documentation for Visual Basic 5.0 and 6.0
