Sending the DDE topic WWW_ListWindows to IExplore (Internet Explorer)
returns an array of DWORDS containing a sequence of integers 1-n, not the
HWNDs of windows opened by the Browser as implied in the documentation.
Back to the top
What is being returned is a sequence corresponding to the number of
instances of the Browser that are currently opened. For instance, if three
instances of Internet Explorer are running, then the WWW_ListWindows topic
will return, to the caller, an array of DWORD's containing the integers 1,
2, 3.

The WWW_ListWindows topic can only be used to determine the number of
instances of the browser that are running. To determine the windows owned
for each instance, an API call such as FindWindows() must be used. General
information on finding and enumerating windows is available in the MSDN
article "Win32 Window Hierarchy and Styles" by Kyle Marsh.
