sarguru,

Do you _have_to_ use DDE?  DDE is old and slow and not reliable.  Using the ActiveX interface would be a better option.  Check out the ExcelExamples.llb under examples folder in LabVIEW.

You will have to use the Advise VIs for reading data.  Look at the examples which ship with LabVIEW: 

examples\comm\ddeexamp.llb

Especially the Advise Client.VI.
