Why is Execution Property not reporting correctly?

[Mark_L]

I read the Execution property but it does not seem to report the setting correctly.

What am I doing wrong?

The next question I have will be how to set it programmatically.  

[Sam_Sharp]

If you look at the help for the ReentrancyType property, it says that it returns either:
0 - Share clones between instances
or
1 - Preallocate clone for each instance

This means that non-reentrant isn't even an option. There is an additional boolean property for whether the VI is reentrant (and if enabled, one of those options above applies to determine the type).

See here: http://zone.ni.com/reference/en-XX/help/371361R-01/lvprop/vi_exeis_reentrant/

Excellent.  Thank you. 

Next, I need to figure out how to script changing the Execution Type for all the VIs in a directory.

In addition to what Sam said, you may notice that this property is not settable while the vi is running.

To change it, you need to open a reference to the vi (while not running) in another vi, where you are allowed to use this property in Write mode.

Of course, you can do this only at development time and not in an exe, where this property is always Read Only.

Ok, I did not seen your last reply.

Build a list of all vi paths and open them with Open VI Reference.

[Mark_L]

It works. 

Thank you very much to both of you.

Here is my example if it is helpful for others.
