The most complex VI file

[Mefistotelis]

I sorted all the extracted LV14 files by size, and one stands out.

Size of Block Diagram in XML form: 15MB

And the size is not due to some binary blob stored inside - no, the is just a lot of parts in the block diagram heap.

Amount of XML tags:

# xmllint --xpath "count(//*)" ex_allChanPropsMod_BDHb.xml
234903

File: vi.lib/Platform/express/ex_EditUserDefinedProperties/ex_allChanPropsMod.vi

And its content isn't even that impressive:

There are just a lot of cases hiding in the "Case Structure", and a lot of copies of the same chunk of diagram within each case.

Also the file seem to have syntax errors? Is it normal that some library files from NI doesn't even compile?

The DAQmx objects depend on the VISA version installed on the PC. Somewhere between 2010 and 2015 there was a change and recompilation was required.
