Can I ask why you want to use DDE? Microsoft stopped development on DDE quite a while a go and it never worked very well in the first place, imho. LabVIEW still has DDE functions but they're no longer on the palette. They're in vi.lib>platform>dde.llb but I recall ever seeing any Excel examples. LabVIEW 7 does ship with an example called Write Table to Excel that uses ActiveX. NI also sells the <A href="http://sine.ni.com/apps/we/nioc.vp?cid=5769&lang=US";>Report Generation Toolkit for Microsoft Office</A> that takes a lot of pain away from working with Excel. You can also search this forum for mention of Excel and find a lot of discussion and examples. Other examples can be found <A href="<http://zone.ni.com/devzone/devzone.nsf/webcategories/C3E56C69D399361E86256AB7006A9149?opendocument&node=DZ53003_US";>here</A>. Lastly, Export Waveforms to Spreadsheet File and Write To Spreadsheet functions give you the ability to create text files that Excel can import. I usually prefer this because I don't have to have Excel installed on the same computer that's creating the file.
