Hello Ajit, You might want to look through the <a href="http://digital.ni.com/manuals.nsf/webAdvsearch/8D930295FFBF9F7686256D2C00624728?OpenDocument&vid=niwc&node=132100_US";>Using External Code in LabVIEW</a> manual, which gives a good explanation and examples of how to use the Call Library Function Node.
I am still a little confused as to what you are trying to test. Are you trying to test your dll, run your testfile through LabVIEW, or both? If you could provide some more details as to what you want to examine, I would be more than happy to help you further. Good Luck! Jeremy L National Instruments
