Using the property loader to load strings into an array

Hi,

I would like to use the property loader to load several strings from a text file. These strings will then be put into an array. I have found a partial solution to this, but it requires the array element to be used. For example:-

Text File

START

<Step Name>

<Locals>

arrayString[0]    "Element 1"

arrayString[1]    "Element 2"

END

 

Property Loader

Selected:

Locals.arrayString[0]

Locals.arrayString[1]

This is not very flexible as every time a new string is added to the text file, the array size needs to be redimensioned and the property loader needs a new entry.

Is there a way of not having to specify the array element in the property loader and having the array re-size itself based on the data loaded into it? ( I tried the below code and it does not work, is there something similar I can do? )

 

Text File

START

<Step Name>

<Locals>

arrayString "Element 1" "Element 2" "Element 3"

END

 

Property Loader

Selected:

Locals.arrayString

Thanks

Hi Kevin,

Try this example from Antonio http://forums.ni.com/ni/board/message?board.id=330&message.id=8043&requireLogin=False

I think this facility was added at TestStand 3.5.

Hi Ray,

That's exactly what I needed to know.

Thanks

What I did is to define the array as a string on the Properties TXT file:

TestSeq.SoakTimeTXT "{\"20\",\"20\",\"0\",\"20\",\"0\"}"

and then at the post expression of the property loader step put this text into array format with the syntax below:

FileGlobals.TestSeq.SoakTimeArray = Evaluate(FileGlobals.TestSeq.SoakTimeTXT),

After this the variable FileGlobals.TestSeq.SoakTimeArray = {20,20,0,20,0}

I think this is a good option for small 1D arrays.
