Search 1D Array complexity

[SPM]

Well, I've tried to save LVOOP objects as variant attributes, but I suspect that not all the data members of the objects are getting stored properly in the attributes. For instance, I have a private member called "name" that never comes back initialized, even though it goes in initialized. Also, I'm getting the base class back rather than the derived class I put in. So I suspect that variant attributes don't get along too well with LVOOP.

Any confirmation or refutation appreciated. Will cook up a simple example and post.

Thanks,
- Steve.

OK, here's a simple example. Run the "Run Me" VI, then clear, set, and get.

It occurs to me that the problem can be worked around by using an array to store the objects and saving an index to the array as a variant attribute.

Update: Tried the workaround and it still doesn't work. It looks like the derived class of the object and the private data are being lost in the tunnel out of the case structure in the registry VI.

Update: Found the problem. Putting the loop inside a case structure doesn't work for some reason. Moving it outside the error case works.

Why? Beats me...

Take a *really close* look at your "Set" case on Registry.vi.

There's a wire that runs out from the edge of your case structure to the edge of the while loop. Right click on it and choose "Clean up wire".  What you'll discover is that your output isn't actually wired to the thing you think it is wired to.

Thanks, Aristos. I got that one yesterday.

But it wasn't what was causing the problem.
