Darren's Weekly Nugget 02/08/2010

Hey Darren,

Nice nugget.

I'm trying to reproduce it, and I get error 1136. Any idea what that's about?

Thanks

[Darren]

Your tree needs to have an item in it called 'a' before you run the VI.

Any plans on glyphs in multiple columns for the MCL, like in your example finder?

That sounds like a good idea for the Idea Exchange.

[ErnieH]

Its there.

But if it is already available, just post it to your users. In addition, publish all your special ini settings. Also, make SBRIO more available for purchase in small quantities. That's it for now. Thanks.

One additional thing:

I once created an 'upgrade tool' that would show the contents of a folder and subfolders in a tree control.

I wanted to display the system icon for each registered file type that  was displayed in the tool.  I used a private method of LabVIEW (Get Shell Icon of File) to retrieve the glyph, then loaded this into the symbols array of the tree.

I've attached the low level VI that retrieves the shell icon, but the VI is password protected. ( vi in LabVIEW 8.6)

This type of VI might be a nice addition to the standard LabVIEW libs, or may even already exist (I couldn't find it).

I just noticed this Nugget.  A while ago I had created a toolkit that extracts the icons from exes and associated files in windows and converts them to LabVIEW image types for use in tree controls and for extracting images for VI icon generation.  At the time I hadn't come across this nice private method.  If any of you are interested, here is the VIPM package for it.  Let me know if you find it useful.  A description of it is here: IconExpress

How did you get access to the "Custom item Symbols.Set Symbol" property?....any reason you did not just upload the vi?

Set Symbol is a method, not a property. I guess it's not so obvious when using implicit invoke nodes, like in the screenshot.

Darren,

Thanks for the quick response!. Yes, it's odd you cannot tell what alot of things are from the diagram icons. Also browsing the vast list of properties is not easy either, using the search works, but I notice that the 'displayed' property label, will sometimes not be exactly the selected description label.

Ah, the joys in the easy life of LV coding.

Regards
