Write/read arrays of clusters to/from file

[Thomas Åberg]

Hi,

I have a problem when trying to read an array of clusters from a file.
I have a multiple set of parameters stored as an array of clusters that I
want to be able to write to a file and later read back.

Is there any special things to do when handling arrays of clusters?

If I do the same operation without putting the cluster in an array
everything works ok.

There's nothing special you have to do.

I just did this exact thing a few weeks ago. I'm not sure how much I can
help -- it depends entirely on how you wrote to your file. I just used plain
text and created a comma-delimted file.

My cluster array's clusters included all sorts of data types (including other
arrays). What I did was to create one huge array in the beginning, and then
parsed it (I knew one array element from another because I timestamped them
when they were created, so it acts like an ID number). Then I just rebuilt
the cluster/arrays.

Hello Umesh,

LabVIEW 8.0 makes it a little easier read and write cluster data to a file.  If you have the cluster that you would like to use, you can just connect a control or constant version of this cluster to the Create/Open/Replace Datalog vi.  You can then create an indicator from the Read VI.  This will give you an array of data from the datalog file.
