problem with data loading from subvi to another vi

[nkf]

Hello

i have a problem with data loading from a subvi to another vi, the situation is i create a cluster and contained 4 arrays in a subvi,

now i want to pass the data that contained by these arrays to another cluster inside main vi.

I load the subvi to main vi and directly connect the two clusters, but i found no data came out from the subvi. so how can i do for this

problem.

thanks

how did you load the data in your main vi?  can you post your VIs or do a screen capture of them?

Hi,

if your clusters are different you have to use "unbundle" and "bundle" cluster functions to extract each array from the source cluster and copy it to directly into the array element of the destination cluster.

see some labview examples

thanks

Hi,

if I understood well your problem is a little bit different: you have to send data from a cluster to a listbox (I did't see any other cluster in your main vi).

See this example.

are you trying to load Data Storage into Main VI?  where in Main VI did you want to display it?

hi, i am using version  6.1, i can not open your sample that you attached, can you attach another one for me, thanks

oh yeah, i realized i made a mistake, actually i hope insert the data to that 2D array and then display the things in the multicolumn listboxes, now i found i could not get anything from the subvi, therefore, i can not link them together.

thanks

one thing i just noticed in your subVI, is it suppose to be an infinity loop?  nothing is returned because your loop never finishes (so the subVI never finishes), you might want to use shared/global variable to synchonize between the VIs

oh, can you give me some detail information for that, thanks.

oh, actually it should not be a infinity loop, do you mean  the problem is because it does not have a terminal in my loop.
