get variant attribute

[max]

I m using LV 6.0.2, the function "get variant attribute" does not work. I
get nothing out of it: no error, no values.
Any idea?!

Actually I could need exactly the string that is shown in a variant
indicator/control.

e.g.:

'Cluster': cluster of 2 elements
'Array': 1-D array of
'Numeric': double
'Boolean': boolean

'Array' -> (2.000E+0, 2.000E+0)
'Boolean' -> FALSE


Has anybody an idea how I can get this as a string?
Thank You.

Max

Max,

To get a Variant attribute, you must first set one. These were designed to send more than one data element over DataSocket (so a string will be the main data item and a boolean will be an attribute). See the DataSocket with Properties examples that ship with LabVIEW 6.

The reason you can't get an attrivute of the vairant is because your variant doesn't have any. Use "Set Variant Attribute" to add an attribute to your variant, and then you should be able to read it back later using the "Get Variant Attribute".

Shouldn't the function "To vairant" set these attributes automatically from the names of the variables?

When I make an array called "Wavelength" and include tha values 0,1,2 in the array and use "to variant", the result is:

'Wavelength' -> [3]
(0, 1, 2)

When I use "set attribute", name it "Wavelenth" and put in an array with values 0,1,2 I gat

1 Attribute(s):
   'Wavelength' -> [3]
(0, 1, 2)

Not a whole lot of difference, if you ask me. The "to variant" function should do this automatically and save programmers a lot of trouble.
