text content of variant indicator ?

[Olivier Zimmermann]

Bonjour,

How can I get the text content displayed by a variant indicator, to write it to file for example ?

Hi OZ,

Communications>>>ActiveX>>>Variant to data
will convert a variant to any LV data type. Just wire a constant (i.e. string constant) of the correct type to the top and it will adapt to produce the data type you need.

Use the new LV 6.1 vi called convert to XML, this will expose the text
inside a variant indicator so that you can process it.

This produces the error "Incompatible variant data type". If anyone does know the answer I'd be most grtaeful.

When using LV 6i, I 've been looking for a way to programmatically read
the text displayed by a variant control/indicator. I tried using a
home-made type converter... but it seems there is no easy way, with that
version of LV.

Now with LV 6.1, you can use "Data Manipulation \ XML \ Flatten To
XML.vi" to obtain this text ; it is quite easy to parse then.


Anybody knows some other ways...? - oz

Hi,

I've spend a lot of time looking for this. Hacking into the data structure,
and converting it to string for each item seems the only way.
