Are you trying to close the VI interactively, or programmatically?

Scripting properties and methods are not supported in the run-time engine, so a built EXE does not have the ability to perform VI inspection.

Sure, here you go. Saved in LabVIEW 2012.

"I'm guessing your bug is here, and I bet it gets fixed if we refactor to remove that second event structure."

I have said almost those exact words on more than one occasion.

Open your main VI, press Ctrl-F, select "Objects", and specify a MathScript Node as the item to search for. Assuming your application doesn't call any dynamic VIs, and you have the "Search Scope" set to <All VIs in Application Instance>, this should find all the MathScript Nodes in your application.

I just updated my OpenG libraries in LabVIEW 2013 and everything looks good. For posterity, the new palette object names I observed were:

OpenG Array Palette

Empty Array? (OpenG)

OpenG File Palette

Build Path (OpenG)

Strip Path (OpenG)

OpenG Time Palette

Tick Count (ms) (OpenG)

Wait (ms) (OpenG)

Wait Until Next ms Multiple (OpenG)

With Jim's changes, all 6 of these OpenG VIs are now droppable with Quick Drop, and they display the proper owning palette when you right-click them.

Thanks for implementing the fix, Jim!

(Please lobby to make this public in the next version of LV)

I have added a link to this post to the CAR, and indicated that we should prioritize this over some of the other CARs I've filed about moving private stuff to public/scripting.

I discovered another reason, independent of Quick Drop, that these duplicate palette name issues should be fixed. When you right-click on a subVI, you don't get taken to the correct owning palette for identically named items. Right-clicking on an OpenG File VI should show the OpenG File palette, like this:

When doing this on the "Build Path" OpenG VI, it shows the File I/O palette instead:

Would you consider this a Quick Drop bug (that brackets in a VI Window Title would cause a failure of QD)? Might want to generate a Hash of the name and use it as the UID/reference for each item that appears in the list, rather than reference by name.

I suppose you could consider it a "bug", although this is the first time in Quick Drop's six-year history that I've heard of somebody wanting to include a bracketed suffix in a palette object name and have it *not* refer to the owning library.

Speaking of libraries, I just confirmed with Stephen that, if you namespace an existing VI with a library, but leave the VI's location and name on disk unchanged, then existing code that links to that VI should automatically relink to the newly-namespaced VI without issue. We've used this trick at NI on several occasions when adding library namespacing to existing APIs...I see no reason why it wouldn't work for the OpenG libraries as well.

So again, the very low-budget solution to this issue would be to figure out the OpenG palette objects that share names with core LabVIEW functions (it looks like there are about 6 of them from the discussion above) and add an "(OpenG)" suffix to their window titles. The more elegant solution would probably be to add libraries to namespace the OpenG VIs.

And looking forward, I've never particularly liked palette VIs that have different palette names than their VI filenames (the exception being Merge VIs). Hindsight is 20/20, but I probably would have just named these VIs something like "Build Path (OpenG).vi", with no custom window title/palette object name, from the start.

Would it create any problems (for Quick Drop) to use brackets in the VIs window title so that it looks a little more like what Quick Drop adds to LVLIB members?

Unfortunately, brackets in palette object names are treated special by Quick Drop, so suffixing with "[OpenG]" would not work. Any other delimeters (parentheses, braces, etc.) should work fine, though. I think I'd prefer if we kept brackets as a library name designation, so if you did suffix the OpenG object names, I'd prefer it be with parentheses.

How would it appear in Quick Drop? Would the user be able to visibly distinguish between the OpenG Build Path and the built-in Build Path?  For example, would (or could?) Quick Drop show "OpenG.lvlib:Build Path" or maybe "Build Path (OpenG.lvlib)" / "Build Path (OpenG)".

Palette VIs that are namespaced with libraries (or classes) appear with the library name in brackets, like so:

Quick Drop will list multiple identically-named objects if they are namespaced differently. So one possible solution would be for OpenG to include all of their palette VIs in a library...this would cause both "Build Path" and "OpenG.lvlib:Build Path" to appear in Quick Drop as separate objects.

Assuming OpenG does not want to start including palette objects in libraries, I thought the renaming option was a simpler and more viable solution.

I've been making a pass through all the LabVIEW palette content on my system, looking for duplicate names between palette objects. Since Quick Drop will only list a single object of a given name, I think it makes sense that all unique palette objects should have unique names. I have come across three OpenG VIs that have identical names to built-in LabVIEW functions (and thus, cannot currently be dropped with Quick Drop):

Empty Array? - user.lib_OpenG.libarrayarray.llbEmpty Array__ogtk.vi

Build Path - user.lib_OpenG.libfilefile.llbBuild Path__ogtk.vi

Strip Path - user.lib_OpenG.libfilefile.llbStrip Path__ogtk.vi

Currently, these VIs use window titles to define their palette entry names. Would it be possible to update the window titles of these VIs to have different names than the core LabVIEW functions, thereby allowing these three OpenG items to be droppable from Quick Drop?

Maybe that's it, maybe they used the High Resolution Relative Seconds to get a more accurate time?  Most likely this is not the fix because I think the high resolution time is Windows only which is why it isn't on the palette yet (just speculation).

High Resolution Relative Seconds.vi works on all desktop platforms, and it also works in RT.

Tree:FocusItem doesn't seem to work for me in 2012 SP1 (12.0.1f3) - I get an Invalid Property error: The property is not valid for this class.

Argh, you're right. When I checked this morning I was awash in several open LabVIEWs and checked the wrong one. The "Focus Item" property of the TreeControl class is only available in LabVIEW 2013 and later. I have updated my post above to reflect this. Sorry about that.

I'm ok with that but will the Focus Row property be public?

The FocusRow and FocusItem properties are still private in LabVIEW 2013. I will add them to our internal list of properties to consider moving to public/scripting in LabVIEW 2014.

Nice to see this will be in 2013.  Are you saying that this will be publicly available or that the focus row will automatically be set to the value?

From what I could tell, we were *supposed* to see the focus row be correctly set while editing in 2013, but from my preliminary tests, it appears to still be a problem in 2013, and will thus still require the programmatic workaround.

It sent me a password, but it doesn't seem to work.

In my case, the password they sent me had a lowercase "L" that looked like an uppercase "I". Once I figured that out, it worked for me.

LabVIEW Limericks? 

Yes, Jack asked me to do some again. I promise I won't forget the lines to any this year.

I did get a chance to fix this issue for Quick Drop Ctrl-I in LabVIEW 2013. The issue has not yet been addressed for Ctrl-Shift-I.
