gram was called through its executable using "system exec.vi". The data acquisition screen is coming with function key options for RUN and STOP functions using F8 and F9 function keys. Is there any possibilities to call these function keys from labview 6.0From LabVIEW, you might be able to call Window API functions to first set focus to the 'Multichannel Analyser' window and then to simulate an F8 or F9 key press. Of hand, I can't remember the exact syntax for doing this so you might have to do some research. I know this would involve calling a Windows DLL with the Call Library Function node.
If your 'Multichannel Analyser' is an Automation Server you should be able to call it directly from LabVIEW. You could then send commands and retrieve data from the analyser by using invoke node and property node methods. This idea is similar to calling Excel, Access, etc. from LabVIEW....
