Darren's Weekly Nugget 02/23/2009

Another thing I really don't get is that the maximum nuber of undo's is set
to 8 by default... I usually put it to 80 or something...

YESSSSSSS! I have been wondering if there was some way to do this. I had been forgetting to look for it and now I have found it. I always hated rebuilding something because I couldn't undo enough times.KUDOS!

On the other hand, maybe I should just learn to never make a mistake...

What happens when you open the ini file and put it higher? I bet
the limit is just a numeric control limit, but it might be a hard coded
limit in the undo routines.

Wiebe,

I think U are correct.

Even when I changed the INI settings to 999, in LV Tools>>Options>>Environment, it showed only 99. So I think this value must be having a conditional check (for >99) inside the undo routines when it is read from the LV INI file.

Here it has been stated that this might work...

Emagine how the LabVIEW community feld when "undo" was introduced in LV 5!
And you you'd feel before if you acidentally pressed "del" while you're
brand new state machine's outer loop was selected, while in a huury for
making that deadline.

But if you put 999 in the ini file, LabVIEW might use 999 undo steps, and
when you open the options dialog, it could be trunckated by the data range
of the control. The only way to check is to make 999 changes, and then test
how many of them you can undo 😉 . Sound like a good fryday afternoon
activity!

Wiebe.

Really this is dead-chilling upto my back bone, Wiebe!

You guys were really pathetic in those days.

Partha,

Actually it was difficult for many of us to learn to use undo.  We had been without it for so long, we did not even think in terms of being able to undo.  I would forget that it was even available.

Of course I would not want to be without it now.

For the good of (G), I wonder if one of these might be in order:
1) "Remove Empty Cases" removes empty cases and cases with just wires.  Developers would then need to use this selection more carefully.
2) Overhaul the "Rearrange Cases" dialog:  Add a Delete button and allow us to select multiple cases in that dialog.

(Note:  There are so many things I want to respond to in this thread, I'm going to respond to each one separately, mainly because I can't figure out an easy way to quote multiple replies in a single reply.  So here's my first response)

Jason,

I like both of these suggestions.  Suggestion #1 would probably be pretty difficult to implement.  Ideally, it would only remove empty cases, or cases that only contain linked wires...I don't think I'd want it to delete cases that have wires that are not connected to linked tunnels.

Suggestion #2 would be easy for me to implement if there were some way to write plug-in VIs for the LabVIEW editor.

Either way, I've filed suggestions on both of these.  Maybe we'll see them added someday.

All this talk of LabVIEW preference settings is motivation for me to write my blog entry on my Tools > Options settings.  Maybe I'll get it knocked out sometime this week.

As promised, here's my blog entry on my personal Tools > Options settings.

Thanks for pointing out Linked Input Tunnels.

That was the first I had seen or heard of them.  I must have missed it in the What's New Screen.  And I really don't recall anyone mentioning them on the forums before, other than some old threads were people were wishing for them.

I could have sworn I wrote a nugget about Linked Input Tunnels after the LabVIEW 8.6 release, but there's none to be found.  Oops!  I'll add it to my list of potential future nuggets.
