DDE Link
How can I get Windows XP DDE link to link up to Window NT 4.0 DDE Link in and Excel Spreadsheet. The Excel Speadsheet on the XP machine is using Office XP and the Excel Speadsheet on the Windows NT 4.0 PC is Office 97. Also if this can be done how do I setup the links on each machine the NT 4.0 Machine will be the host and the XP machine will be the client
