How do I determine what element in an array was right clicked on?

I have an array set up on my front panel. When the user right clicks on an element in that array, I would like them to be able select from 3 different options. I have the shortcut menu working, but I need to know which element in the array the user right clicked on to determine what values to change. How can I get the index of the element?
Thanks for any help!
Solved!
Go to Solution.

Couldn't you get index values from the array property node?
Also this doesn't account for if scrollbars are seen or not. And I usually like to know if my range is valid, because again I could be clicking on a scrollbar, or label and still get the Mouse Down event.
Here is one I posted a while ago.

Is there a way of determining what element in an array is being clicked on?

Hi all. I would like to setup an event to determine what element in an array is being clicked on/hovered over. I think I tried this before and found it wasn't working due to limitations of LV 7.0. If this code already exists, it would be great if I don't have to do a scavenger hunt for the solution.
I think one possibility I nixed was to use the refnum of the elements to determine which one it is. IIRC, this is not possible because the refnum of the element is for the edit box only.
The second possiblity is to get the on click event, and somehow determine which element in the array it is. This doesn't sound too difficult as it should be a simple calculation, but may get in to some hairryness based on if the indicies are visible or not, and if I am using a new or old array with new or old control (calc would change based on boarder size of the controls). I might just simplify it by removing indicies and using older control set which has minimal boarder size.
And just for fun, can I force a tool tip to show up?
Thanks all,
A

This is indeed possible, at least in the newer versions I use.
Take the array refnum from the click event data terminal and get a reference to the array element. This refers to the element that was clicked, but you do need to work out how to get the index. My method is to use property nodes to get the screen position and size of the element and the screen position and size of the array, as well as the array's Visible Index property. For each direction, take the quotient of the relative position of the element (account for padding!) over the size of an element.
I suspect that taking the mouse coords and comparing to the array's sizes in pixels is similar, although I trust my method for events that don't have mouseclicks (what coords does Array:shortcut menu selection(User) return if you used the keyboard?)
Here's an old version I happened to have open. I've posted about this before, I suspect I have a clearer version in my gallery. I use this method in my example code contest entry to work out which square of the chessboard is clicked.
Thank you for that one!

How Do I Determine What WUDFHost.exe is Doing and What It's Associated With?

Since around the time of the installation of Win 8.1 Update 1 I've had a couple of new WUDFHost.exe processes that run all the time. Today I saw one of them accessing data on a backup volume, which I assume was some kind of maintenance
activity - but I'm not sure.
My question is this:
How can I determine what these processes are doing, why they're here, and what they're associated with (i.e., what feature or device has caused them to be running). I don't suspect them of causing a specific problem - my system's running fine
- but I want to know why they're running.
Process Explorer shows them to have been started by these two command lines:
"C:\Windows\System32\WUDFHost.exe" -HostGUID:{193a1820-xxxx-xxxx-xxxx-be817523f6aa} -IoEventPortName:HostProcess-ae18c507-xxxx-xxxx-xxxx-ce7a84b73fb2 -SystemEventPortName:HostProcess-76f2d2b0-xxxx-xxxx-xxxx-25de41b0af65 -IoCancelEventPortName:HostProcess-52988628-xxxx-xxxx-xxxx-54018fc05bec

As you can see, their function isn't obvious from what's showing.
What tools can I used to delve further into what these are and why they're here?
Thanks for any help or wisdom you can offer.

How can I determine what is the minimum SCN number I need to restore up to.

Say if I have a full database backup, I know I have file inconsistency, but I want to know what is the minimum time or SCN number a need to roll forward to in order to be able to open the database?
For example: I do a database restore.
restore database ;
RMAN> sql 'alter database open read only';
sql statement: alter database open read only
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

ORA-16004: backup database requires recovery
ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 1: '/u01/oradata/p1/system01.dbf'
I need need to apply archive log files. All references I find for ORA-00194 state the solution is to "apply more logs until the file is consistent " But "HOW MANY LOGS", or more apporaite up to what time or SCN? How does one determine what TIME or SCN is required to get all file consistent?
I thought this query might provide the answer, but it doesn't
select max(checkpoint_change#)

I've discover I need to apply archive logs until this query reports all datafiles as FUZZY=NO , but this only works by guessing at some time periord to roll forward to, then checking the FUZZY column, and try again. Is there a way to know, I have to roll forward to a specific SNC in order for all my datafiles to be consistent?
select file#
     , status
     , checkpoint_change#
     , checkpoint_time
     , FUZZY
     , RECOVER
,LAST_DEALLOC_SCN
from v$datafile_header
order by checkpoint_time
Thanks,
Jason

The minimum point in time is the time when the last backup piece for datafiles in that backup was completed.
Your alert.log should show the redo log sequence number at that time.
You can query V$ARCHIVED_LOG and get the FIRST_CHANGE# of the first archivedlog generated after that backup piece completed.
A
LIST BACKUP;in RMAN should also show you the SCNs at the time of the backups.
You can also query SCN_TO_TIMESTAMP -- eg
select timestamp_to_scn(to_timestamp('15-MAR-09 09:24:01','DD-MON-RR HH24:MI:SS')) from dual;will return an approximation of the SCN.

How do you determine what shows are in free video on demand?

How do you determine what to include in the free on-demand shows? The Mentalist was always there before but is no longer. This is especially important for shows like the Mentalist and The Good Wife which come on Sunday nights after sports events. Even if I set my DVR to record 60 minutes over it doesn't always catch the entire episode. Would also like to see Person of Interest there. And last but not least, you should have a way for people to access netflix or other services from your service.

If you go to BROWSE then the FREE folder you will find that everything in there is free viewing. If you go elsewhere and try to watch a paid show, you will get a prompt asking you to purchase. It also shows the amount of the movie before purchase.

How do I determine what the default font for equations is?

In the Equation Fonts dialog box, we can set the font of Functions, Numbers, Strings, and Variables. In those dropdown lists, there is a Default (para) Font choice. How do I determine what font that is? What paragraph tag is associated with an equation?
With all the choices set to default, numbers types in the equation look similar (but not exact) to the Symbol font, but of course typing letters in the Symbol font reveal greek characters. So is it some derivation of Symbol?

Thanks. That .cfg file shows Times Regular for the following characters, but none of these characters are the regular alphabet, (are they?) so there must be yet another place?
mathchar.cfg    53      < plus        2b Times Regular>
mathchar.cfg    54      < equal       3d Times Regular>
mathchar.cfg    70      < gg          c8 Times Regular>
mathchar.cfg    71      < ll          c7 Times Regular>
mathchar.cfg    93      < fact        21 Times Regular>
mathchar.cfg    94      < dagger      a0 Times Regular>
mathchar.cfg    98      < minus       d0 Times Regular>
mathchar.cfg    106      < uequal      3d Times Regular>
mathchar.cfg    112      < diff        64 Times Regular>
mathchar.cfg    116      < ucomma      2c Times Regular>
mathchar.cfg    117      < semicolon   3b Times Regular>
mathchar.cfg    118      < optotal     64 Times Regular>
mathchar.cfg    127      < power       5e Times Regular>
I've determined (by comparing equation string to body string visually) that Times is in fact the font being used. I just don't see yet how that gets determined. Any further thoughts?

How do I determine what URL to use when launching to display a RH10 .htm page?

Hello,
We are implementing RoboHelp 10 for our online documentation and are sourcing it from Framemaker 11. I am trying to determine exactly what URL information the developers need to build for the launch to the specific IBM System i screen. Is anyone launching RoboHelp from a backend ERP system? If so, how did you determine what level to use when building the URL for that page? Thanks for any assistance you can provide.

It depends on whether you just want to open the help at the default topic or open context sensitive topics.

How do I determine what 4 computers are authorized to download content from my account?

How do I determine what 4 computers are authorized to download content from my account? I need to manage what computers are authorized.

You can only see a count of how many computers are authorised, you can't see a list of them. If the computers are also associated to your account (e.g. you've used iTunes Match, automatic downloads, or redownloaded past purchases on them) then they might also show in the 'manage devices' section of your account on your computer's iTunes (Store > View Account menu option): Manage your associated devices in iTunes - Apple Support
You can also, once every 12 months, log into account on your computer's iTunes (Store > View Account) and deauthorise all computers and then reauthorise the computers (which you can only do directly on them) that you still have and need.

How do I determine what version of Apache I'm using?

How do I determine what version of Apache, 1.3 or 2.0, I'm using?

If you're using the stock Apache, it's 1.3 on regular OS X. I think it's Apache 2 on OS X Server, but I'm not certain.
If you're asking because you've installed Apache 2, but want to make sure it's the one that's running and not the stock Apache, one way to tell is to examine the headers it returns. This Terminal command will show your headers (just enter it and hit the "return" key):
<pre class="command">curl -I http://localhost</pre>
Here's what I get:
<pre class="command">HTTP/1.1 200 OK
Date: Mon, 02 Jul 2007 13:09:06 GMT
Server: Apache/1.3.33 (Darwin) PHP/5.2.0 mod_perl/1.29
Content-Type: text/html</pre>
As you can see, I have the stock Apache, but I've installed PHP5.

Mac shut down due to problem; I rebooted fine. how do I determine what the problem was?

mac shut down due to problem; I rebooted fine. how do I determine what the problem was?

When shut down and rebooted, the Mac OS X does background maintenance on the system. That can solve minor issues.
Beyond this, it is a good idea to run Disk Repair yourself just to make sure.
Reboot with the option key held down. On the screen that comes up select the Recovery disk icon and Continue.
On the next screen Clcik Disk Utility and Continue.
In DU, in the list on the left select the drive to be repaired - click the item that is indented to the right, not an an item whose name starts on the far left.
Click First Aid, then Repair Disk.
After that is done, quit DU and restart as usual.
