From: Henrik Volkers on
First startingpoint: search the NI Dev Zone&nbsp;&nbsp; with DDE you get (for example) <a href="http://zone.ni.com/devzone/conceptd.nsf/webmain/14134D7CE042EDBF86256A3A006BD87C" target="_blank">http://zone.ni.com/devzone/conceptd.nsf/webmain/14134D7CE042EDBF86256A3A006BD87C</a>
Contact the manufactor, ask for DDE examples (even some C or VB examples can help)
RTFM
