and commands to DDE Server applications. Many popular Windows applications
provide support for DDE, including Microsoft Word, Microsoft Excel, ACT!,
WinFax, Netscape and many others. It could be used,
for example, to communicate with Netscape to tell the browser to reload
the page or with Excel to populate a cell with data
