Open VI Reference Function in an Executable

[Kamilan]

Hi All,

Is it possible to call a sub-VI (which within itself calls other sub-VIs not included in the executable source files) from an executable (LabVIEW 2011).

I have no problems calling the sub-VI via "Open VI reference" when runing the main vi as is. As soon as i build the execuable, search for the intended subVI the exe"looks for a few items" then stalls.

The subVI controls a few comports, and prompts the user to take some actions. The SubVI requires an input from the Main VI and when completed outputs a cluster of for the Main VI to continue.

Hi,

File path's use to be the most common issue when building .exe's.

Add a debugging dialog popup window displaying the path.

Hi Roger,

Do you mean the file path to the subVI or the exe?

Thanks

Hi All,

Firstly the main error was "1031 ~ VI Reference type does not match VI connector pane."

Secondly, the subVI had a dependency on "Space Constant.vi" which is stored in the vi.lib, The Main executable did not have "Space Constant" in its vi.lib.

SOULTION

1. Added a "space constanst" to the executable project.

2. Ensured that the Refnum type was not "strict" (also ensure refnum matches VI pane)

becuase I am using a cluster, if the main cluster changes for any reason, you must update the inputs and outputs of your subVIs. This was achieved may making the cluster a control type def. However, because some subVIs are independent from the main, I have to ensure I use the lastest controls when building independent subVIs.

This allowed me to run the subVI.

Thanks.
