LV Runtime Description

[bfarley]

I'm looking for a short (one paragraph) description of what the lab view runtime consists of and what its purpose is

Thanks,

Straight from the LabVIEW Help:

"You must install the LabVIEW Run-Time Engine on any computer on which you want to run LabVIEW applications or shared libraries. The LabVIEW Run-Time Engine includes the libraries and other files necessary to execute LabVIEW-built applications and shared libraries. All client computers running LabVIEW-built applications and shared libraries must also have the LabVIEW Run-Time Engine installed."

Thanks, let me be a little more specific. Is the runtime "in control" of an application or is it just a library of overhead routines called by a LV executable? I read somewhere that the LV Application builder produces true Win32 binaries - but that doesn't see mto square with LV havig a "run time engine"

Thanks,

A built LV executable calls the routines in the run-time engine. You can have multiple executables with a single instance of the run-time engine installed. The .exe files are smaller as a result. Once upon a time, the building process included the run-time engine and this resulted in some pretty big files. You can think of the run-time engine as the LabVIEW development system with the "development" part - no editing, re-compiling. The actual exe file is your compiled LabVIEW VIs saved without diagrams. If you change the extension of an exe to llb, you can actually use VI Library Manager to see which VIs are in there.
