Return Code of a Labview Standalone Executable

[jcr]

Does a standalone executable built with Labview return a RETURN CODE?

If yes, is there any way control the value of this RETURN CODE?

No. Executables don't return anything. I would look into returning a value from a LabVIEW DLL instead of using an executable. LabVIEW DLL's can be created from Tools>>Build Application of Shared Library(DLL) function in LabVIEW 6.0 or later.

Hi,

In general, I would agree, but executables (.exe) can contain functions. For
example, create a Call Library Function, and type LabVIEW.exe in the Library
name... This is an executable, and does have functions, that do return
values.

It's just one big mess, dll's ocx, tbl, exe, com etc. (e.g. try browsing to
a dll when selecting a ActiveX automation reference, or selecting a ocx in a
Call Library Function... To use a protocol, the file need to have several
required functions, e.g. DllRegisterService for dll's). In general, a return
value it the value of the eax register (on processor level), but this cannot
be controlled in labview. So creating a LV dll is good advice.

Regards,

Wiebe.
