I have an idea. Should we move this thread and other potential CR candidates to a special "CR in-development" area to better facilitate this? I think there is enough momentum here to justify this. After a bunch of thrashing, we can produce some decent CR code. Thoughts?

Qualified Name Array To Single String.vi takes a VI's qualified name, given as an array of strings, and converts it to a single colon-delimited string. This VI may be useful for working with VIs owned by any library type, and it is used as a subVI of the other two VIs in this .zip file.

Is This Control Of This LabVIEW Class.vi takes a control refnum and a LabVIEW class refnum and tells whether the control is an instance of the given LabVIEW class. It returns true for regular class controls/indicators and for XControls of the class.

Is This Control Of LabVIEW Object Class.vi is the same as the previous, except it does not take a class refnum for input. LabVIEW Object is the built-in class that is the ancestor of all other LabVIEW classes, and this VI specifically checks to see if the given control is an instance of this class.

I'm pretty sure I saw outline mode just a few days ago. It was probably when clicking on search results...

I have a better idea. Why doesn't someone start a wiki article that answers this question since it's been the 1000th time someone has asked this on the forums. We currently have a calling a VI category which has bits and pieces but no one comprehensive article. There realy is many ways to call a VI let us list the ways and what are the differences. An overview article is really necessary here.

In the LV User Group Meeting during VIP 2007 (last week's NI congress in Germany), the NI people told us that LV 8.5.1 will be released "in a couple of months".

Sure, and probably some time after that you will see LV 9.0. Oh and probably sometime after that you will see 9.1 then 9.1.1 then 10.0 then... So?

Threaded and outline mode was removed because it causes more problems to 95% of the people than the benefit it offered the few that liked it.

Welcome to the forums, but what's with the attached image? You can't possibly think that's friendly.

I understand (or at least I think I would understand, if I cared to delve into it ) the reasons for it, but having a runtime-engine that's pushing 100 MB...

I prefer at least to always remind everyone that the 24MB run-time works just fine thank you.

I would recommend this for a Code Repository candidate. Please consider.

What kind of "callback" VI are you referring to, i.e. how specifically is the VI being called?

-D

Using the Register Event Callback node.

Ok, this may be a bug, I (or LabVIEW) may be retarted, or fill in the blank. How do you debug callback VI's? I assumed that you could just put a breakpoint in the callback VI and the instance would break, but it doesn't. Any ideas?

It never ceases to amaze me where LAVA threads end up... but still, looking for LAVA lurkers out there. Just post and say Hi.

crelf, you're talking to an NI employee. They don't work like system integrators.

I tried to extend Michael's code in a simple-minded way to handle multiple events, by adding another element to the RegEvents terminal. Suddenly I was no longer allowed to connect to the dynamic events terminals! I could still select any event I wanted for RegEvents, as long as there was only one event. I don't see why this should be...

Sorry Dave. Here's how to add more items. We won't get into why this happens. Suffice to say that the registration refnum is typed to the data and because the uninitialized shift register is well, uninitialized, it retains the datatype. You need to type the wire by feeding in the registration refnum data from the outside of the while loop. We can't wire anything from outside the loop because this Facade vi runs only one iteration and the shift register retains the value from the previous run. To make a long story short here's what to do in 3 steps:

BTW, you don't HAVE to change your display name... just thought some people might want a space between their first and last name.

I’ve always wondered who all these people are that visit the LAVA Forums but never post. There’s about 7000 registered members but only a handful post irregularly. I know many of you subscribe via RSS and never visit the site. Now’s your time to shine, lurkers! Just pop a comment here, no reason to be shy. Let us know who you are, where you’re from, what you do, whatever. It will help you get to know some of the other lurkers. . For those of you still scratching your heads as to what a lurker is, a lurker is a person that decides to stay shy in either a chat room, a forum or a blog, by not contributing their comments and electing to just watch the babble ensue in front of them. Now that made no sense, but I’m sure you got it.

And yes, if you are one of those regulars you can comment too.

Just want to let you know that as a courtesy to normal members. I am allowing you to change your display name once. The opportunity do do this expires on Sunday night. Some display names are ugly because of a previous login limitation prohibiting spaces or underscores. I have lifted this limitation so now you can beautify your display name and use spaces or underscores or whatever.

Note: this is a one-time deal. Make sure you are sure of the new name because you won't be able to change it starting Monday.

You can change your name in your control panel. on the left side select Change Display name.

It seems that based on AQ's earlier post, there is no solution other than to create 9 VI's.

Here you go.

Edit: Sorry, just realized you need the status of the file not the control. Hmm.

I can only get this across with some real code. Find attached a working Xcontrol that does this in 8.2.1.

Edit: In my rush i forgot to add the destroy code, but i think you can take it from there.

You can use the Init ability, only make sure you use a dummy registration (as I showed in my Nugget and NI in their example) in the Init.

If there's the need for the event registration write the correct control reference to the event registration (if I'm right that's exactly what I did in the Boolean XControl).

Ton

yes, this should work if you use a null ctrl refnum constant.
