Size of a Teststand container

[R1M]

Hello,

We have a Teststand sequence that manage a set of data in a container.

This container should be filled in from a DLL in CVI.

We are able to send CVI a pointer to the container, to create a copy of the container structure in a C structure, fill in the C structure and then memcpy data to TSStand container (through the pointer).

All is OK excepted when one side or the other updates structure (add, remove, move an element): very difficult to check consistency.

I found this thread https://forums.ni.com/t5/NI-TestStand/Best-way-to-pass-an-array-between-TestStand-to-CVI/m-p/1530686... but it said it is an old method (for TS <3.0). Is there a better method to do the job?

Hello R1M,

I advice you to consult these 2 papers:

* How To Create a DLL from a LabWindows™/CVI Instrument Driver

* Using Dynamic Link Libraries with NI LabWindows™/CVI™

The easiest way in my opinion to handle struct and match it with container is to add a .fp file (part 4 of the second link).

Hope it will please you.

Bye!

it looks interesting.

To be tested in coming days.

Is there any update on this topic? We have not found the method to integrate the structure in a .fp.

[R1M]

1) What is this warning for? Does it means it is not possible to pass through .fp structures containing structures (struct in C language)?

(see attached picture from help)

2) how should .fp be integrated in the .seq?

[R1M]

We can't find the solution: no way to share a structure between CVI and Teststand, with consistency checks (minimum is size, maximum is full list of nodes).

Is there a chance to have a solution, or a consistent example, in a short time?
