Hello Asif,

I suggest you to post your question in  the LabVIEW forum, this one is for another software of NI, LabWindows/CVI. Good luck!

• Define "open"
• Define "step 7"
• Define "software"
• What button?
• Do what?

 (Are you talking about this? Please be much more specific!)

You can launch other applications by running their executable. Check out this example using the System Exec VI to launch an executable.

You can also use System exec to Start a file and it will open in its default program. Give it a try with your PDF.

The first question I have is.. why?  What's the point of using the DSC module if you're looking to open the third party software anyway?  Isn't that performing the same task twice?

After that, again, "define" is important.  Are you just wanting to open the program?  If so, use a sysexec call.  But, that's going to look pretty shoddy.

Instead of telling us the steps required to get to your potential solution, describe the problem.  "I have x hardware.  My goal is to show y information.  I have z software available for this task."  It's more likely we'll find a cleaner solution that isn't a direct answer of your question.  The questions you've asked are leading to something incredibly janky.

Hi Asif,

please don't create double posts/threads on the same topic.

I merged your threads…

(When you create double posts by using copy&paste you should atleast try to remove typos… ;))

You make an Event structure that handles your button presses. In the relevant event, you use a System exec with e.g. "cmd /c start [pdf-path]"
