"Edit Find" coercion dots, Recommended terminals, empty Description, etc

Are there ways to use LV's automated Find capability to look for any of the following items?
Coercion dots
Connector terminals for which connection is "Recomended"
Controls or VIs for which the Description or Tip is blank
Wires that go behind objects
Wires that graphically are shown touching a terminal but that are not logically connected to it
Objects that logically are inside structures like loops and case statements but that graphically are out of view (beyond the graphical edge of the structure)
Dataflow running right to left on a wire
Variables that are written to in zero places or in more than one place
Controls and nodes whose only output terminal is unwired
Unwired Error Out terminals
I'd like to be able to search through a VI and everything inside its heirarchy for the above things - going through and noticing all their occurances could be good for a project. Some of these are pretty clearly programming errors. Some of them are bad practice, or at least the preference to avoid can be a useful strategy or check. Some of these things are perfectly legitimate to use frequently, but glancing at all the occurances of them gives an opportunity to notice otherwise hard to spot errors. AFAIK LabVIEW doesn't allow searching for them, though it would be able to recognize them.
For any of these, is there a way to Find them?

I think that almost all of the items you listed are coverd by the VI Analyzer. It will find and list all of the offenses, let you browse to each case, and produce reports if you would like.
[Set PunMode = True]
It can be customized in the event you think the "out-of-the-box" configuration warrents it being renamed "VI-ANALyzer".
[Set PunMode = Flase]

Coercion dots, Typedef. and Property Nodes

Hi,
following problem:
1. I place a simple Control (Button 1) and connect it to an Indicator (Indicator 1) -> OK
2. I place a Button as Typedef. (Button 2) and connect it to an Indicator (Indicator 2) -> Coercion dot on Indicator 2 (I don't see the point of a boolean coercion, but OK)
3. I create a property node for Indicator 1 (Value) and try to connect a constant (right-click>Create>Constant -> the constant is grayed out and the error message is 'type definition not found or contains error'
Details: The master copy for this type definition could not be found or the master copy has errors. You must find and fix the master copy, or right-click this type definition and select Disconnect.
4. I remove Button 2 and repeat step 3 -> the same thing happens
If I connect an existing boolean constant to the property node there is a coercion dot. As a matter of fact for using one Typedef. Control in a VI all other control property nodes suddenly have coercion dots even if I remove the Typedef. control. Does it mean either all controls and indicators better are typedef. or none at all?
Thanks in advance.
P.S.: the problem occurred originally in a VI with much more than two buttons...

Why this coercion dot on array indicator from strict typedef?

Why is there a coercion dot on the second control?
I created a trivial 3 element array of doubles, and created an indicator by right clicking on it in the block diagram. That's the "CreateIndicator" control.
Then I did the same thing to create a second indicator on the same output wire, and from the front panel selected it and customized it to a strict typedef, saved, and applied changes. That's the "CreateIndicatorThenCustomize" control. It has a coercion dot on it, though. Why?
Thanks to anybody who can shed some light on this for me!

Thanks, Ben!
Seems weird that this would be considered a coercion. Why do they do it this way?
Q1)
What is the falicy? Is it that you should avoid coercion dots because they force copies, and yet in this case there is no copying involved so the avoidance advice is incorrect?
Q2)
Also, different question, why is Customize Control grayed out in the front panel Edit menu, as long as another control customization panel remains open from the previous use?
Q3)
Finally, how did I miss this after all this time? Well, you probably don't know how I missed it. Actually, if you do know, it might be better to leave it unsaid anyway....
Q1 Correct!
Q2 Not being NI R&D I can only speculate that is was an expediant move to shut-down that functionality. It used to be possible to customize part of a control while customizing a control back in about LV 6. They shut it down making it more painful to do the edits within edits (you can save a control in one edit and then use "replace" to select it while editing the first)
Q3 I will leave taht question as an exercise for the reader.
take care,

How to find out that a record is empty or null

hi
how can i find out that a record is empty or null.
in other languages when a object or record is not initialized it will be null.
after initialization how can i find out its values are null. so far i tried this
declare
v_r_emp emp%rowtype := null;
BEGIN
     if (v_r_emp is null) then
     dbms_output.put_line('record is not initialized');
     end if;
END;
it seems in plsql we can assign null but cannot compare it with null clause why? if we are able of assign null we must should about to compare it with null too.
also how record can be made empty. how can we find out that a record variable is empty
please help me to understand the concept
thanks

You need to check every element in the record.

How do I change the default color (gray) that 'Edit - Find' uses?

When I search for a key word in a PDF file viewed in Safari web page using Edit -> Find
It defaults to highlighting the text it finds in light gray which is very hard to see. I would like to change the highlight color to something much easier to see on the page - like red for instance.

What version of Pages & what version of OS X are you using?
A problem with an early Software Update for Snow Leopard caused a lot of problems. The problem is not whether or not your system is the current version but how it got there. You must use the combo updater, not the one from Software Update unless it specifically states it is the combo. Software Update will only offer the combo if your system is two or more versions behind.
If you're not running the latest versions of the iWork apps & Software Update says your software is up to date, make sure the applications are where the installer initially put them. The updaters are very picky. If the location is not where the updater is programmed to look or if the folder doesn't have the name the updater looks for, it will not work. The applications cannot be renamed or moved. If you installed from the downloaded trial or the retail box, they must be in the iWork '09 (or '08 if that's what you're using) folder in Applications. That iWork folder must be named iWork '09. If it doesn't have the '09 Software Update won't find them & the updaters won't work.

When using Edit Find, I can only type 3 or 4 letters in the Find bar before the letters start disappearing. If I copy/paste a word into the Find bar all the letters will be there. Has anyone else had this problem?

The Find bar opens OK with Edit/Find. I start typing in a word there but it will only allow 3 letters before they disappear and my next keystroke appears. I can copy/paste a whole word or string of words into the Find bar and all the letters remain.

Grep to find double dot

Hi,
Any one can help me to find double dot in a indesign document.
It should not catch triple dot(...) and six dots(......) match

Here's a screen shot:
I colored single dots blue, and the single-character ellipsis red. I've placed them in several combinations. When I run the GREP, here's what it finds:
As you can see, it only found the single dots, and not the ellipses. Are you saying that you have actual ellipses and single dots, but it isn't finding the single dots when they are after an ellipsis?

The same type and red coercion dot

Hi!
A small project is attached to show how red coercion dot appears if you remove"lib type definition.ctl" from library to a virtual folder. It is interesting that this affects only class property nodes. It does not affect class accessors ("setters") and indicators. The same happens if you move "type definition.ctl" from virtual folder to the library.
Picture shows changes in "vi in library.vi" block diagram.
The application works but a peaceful bad feeling remains ...
There are discussions on this NI forum about typdef controls. It seems that using type definitions can cause serious problems if used together with property nodes. What would be suggested in these cases?
Regards,
Ljubo.

I can't unfortunately look at your code right now, but there are a couple points to be made:
I'm not sure the problem you show is a bug. Moving the control file out of the library and into a virtual folder in the project changes the type definition because it has a different name.
LV does at times show spurious coersion dots, but I have never seen it cause a functional problem - let alone a serious one.

FPGA: are typedef coercion dots bad for efficiency?

Howdy--
Using LV 2011 FPGA, I always get coercion dots when reading or writing to/from FIFO or Memory items typed with a typedef.ctl. Do these indicate some extra use of resources in the compiled code, or are they harmless?
Thanks a bunch all, and have a great day.

Edit- Find... Disabled

Why is it that sometimes the Edit->Find... menu item is disabled? I'm trying to search for a string in a .java file but when I click on the "Edit" menu item, the dropodown menu shows the "Find..." item disabled. I've had this same issue happen with SJSE8 as well.

Hello,
I wondered that too, just hit ctl-f, works within source code view

Edit find/change (not finding all instances)

I am using Edit>Find/Change to change a brand name in a document — however, this feature is not finding ALL instances of the brand name. I am having to manually/visually edit through the entire doc. Suggestions?

Hi,
You could check whether "Case sensitive" is switched on in your find/change dialog. Also check that your find format options are cleared. Click the "More Options" button if the find format options are not showing in the dialog.

Coercion dots using classes in conditional structure

I am trying to create a plugin driver that is LVOOP based. We have certain drivers we do not want to release. Therefore I am attempting to use conditional disable diagram to select which class is available. One of my questions is why do I get coercion dot between these conditional disable cases? If these are part of a project packed library, does the disabled conditional code included as a dependancy?
In the below example the release case the base class is used and in the development case the derived class is used.

What brought me to looking at the coercion dots was once they are visible, building a packed library LabVIEW fails to initialize the builder. This issue is not remedied until the offending class is removed from the project and the project is closed releasing the class from memory. If I move the conditional disable out side the case statement there are no coercion dots. Also switching between conditionals disable cases does not change this coercion. When I go to build the packed library LabVIEW still locks up.
In summary I believe that the build locks up when ever switching between conditional disable cases.

FireFox 4 Windows 7: Edit/Find does not work. Find Bard does not display.

Edit/Find or Ctrl-F does not work. The "find bar" is not displayed.

It is possible that the screen is too wide or too high and that the scroll bars and Find bar fall off.<br />
Open the system menu via Alt+Space and see if you can resize that window.<br />
If that works then close Firefox to save that setting.
