How do you measure performance of an item renderer?

I'm creating an ItemRenderer in Flex 4.6 and I want to know how to measure total time to create, view and render an item renderer and how long it takes to view and render that item renderer when it's being reused.
I just watched the video, Performance Tips and Tricks for Flex and Flash Development and it describes the creation time, validation time and render time and also the reset time. This is described at 36:43 and 40:25.
I'm looking for a way to get numbers in milliseconds for total item renderer render time and reset time (what is being done in the video).

To answer your first question, in this video Ryan Frishberg recommends measuring and tuning your code. I'm trying to follow his example for my own item renderers.
I've taken some key slides out to show you.

How do you get to the "Multiple Item Information" window so I can click "Part of a compilation:?

How do you get to the "Multiple Item Information" window so I can click "Part of a compilation"? When I transfer a CD to iTunes, and the CD has ten tracks, it loads as ten different albums. Also, once this happens, do I have to delete the album and start over or is there a way to merge the albums in iTunes? Using iTunes 10.04.08.

And you've made me remember that using the compilation flag may only work in iTunes if you go into the Songs view, then use View > Column Browser > Show Column Browser and then View > Column Browser > Group Compilations to make sure this line is ticked.
It is also best if View > Column Browser > Use Album Artists is also ticked.

How do you measure a Cycle's lenght in time, not bars and beats?

How to you measure the time length on a selected cycle ? I understand that when any cycle is selected, you can see the length of that specific range on Bars and beats, but not in Real time. How do I get to see ( Calculate ) the real time length of a cycle range? When working with video this feature is absolutely necessary. ProTools shows you the length in time when a cycle range is selected. I also know that you can calculate the distance of any given point in the song, relative to the start time, you can see it in the Time Position display, but what If I need a more exact time calculation ( min:sec:frames, etc. ) between two specific cue points that are only relevant to video sync, not relative to the start time and not relative to musical values. Like if I need the exact time length for a video cue, etc.

Thank you, very Much, That's it !!!
I've looked for that for years...LOL, It never occurred to me to look for a "negative",

Just moving from PC to Mac. How do you select a group of items. On the PC it was shift right click

In list or column view, click the item at one end of the range and then shift-click the item at the other end.
In icon view, click on an empty part of the window and drag to select them.

How do you measure your productivity?

Hi everybody,
I have troubles estimating my productivity as a Java programmer. As far as I know "a normal programmer" produces from 80 to 400 lines of code (LOC) per month (comments are not counted).
I now it is very unclear how to define and estimate programmer's productivity a and I know it depends on a lot of factors. But still, I would be extremely greateful if someone would share with me how many lines of Java/JSP code s/he produces per hour (or per month).
A lot of thanks in advance.

How about trying to measure the financial return on the code you produce.
If, for example, you are a reuse asset producer, perhaps you could measure costs on the basis of SLOCRBO (Source LOC Reused By Others)?
So if you write a 1KLOC module that is reused in 10 projects, that's
SLOCRBO = 10 * 1000 = 10,000
You could try to take this forward by gathering stats for the relative cost of reuse for modules produced in your company. Let's say it costs 20% of the cost of writing a module from scratch to use a 'reusuable' module instead. So you can try to work out the amount of money you are saving the company:
CPLOC = (Cost per line of code) = $100 (say)
RCR = (Relative cost of reuse) = 20%
DCA = (Developer cost avoidance) = 10,000 * 0.8 * $100 = $800,000
But you'd need to measure code quality, so you need stats on error rates, and how much it costs to fix errors. This might depend on when errors tend to caught, and how critical the apps the company develops are. So:
ER = (Error Rate) = 0.001 (errors/LOC)
EC = (Error cost) = $10,000 (say)
MCA = (Maintenance cost avoidance) = 10,000 * 0.001 * $10,000 = $100,000
So your Reuse Cost Avoidance would be DCA + MCA = $900,000
Then you'd have to take into account your labour costs, costs of maintaining the reuse program, asset administration and so on. You are also going to need to take into account the impact that your bugs, and any future incompatable changes, are going to have on systems that reuse your code. You could (I think) get a fair idea of what you might be worth to the company, and how much money you could save by increasing Reuse a bit. Obviously, this kind of calculation is going to need statistics from the company to make the calculation meaningful.
You could also look at your maintenance patterns: Do you have to keep making lots of small changes to your code? If so, maybe you could improve your productivity by performing some preventative maintenance - improving the maintainability of your modules by re-engineering them.
I do think it's important that you do try to measure productivity - producing metrics is the hard part - but without taking measurements, how can you improve a software process (either from the pov of a manager, or as a matter of personal improvement)?

SPD 2013 - Copy Document action - how do you update the copied list item's metadata?

SharePoint 2013 Designer no longer has the Copy List Item Action, it only has a Copy Document action. It seems that this action provides no way of saving the copied documents list item ID. How do you update the list item after it has been copied??
Any help is appreciated.
Greg Pierson

Hi,
According to your post, my understanding is that you wanted to copy the list item in SharePoint 2013.
The Copy List Item is
available only on the SharePoint 2010 Workflow platform, you can create a SharePoint 2010 workflow using the SharePoint 2010 workflow platform to achieve it.
You can also use the Content and Structure to copy the list items: Site Settings->Site Administration->Content and Structure.
Thanks & Regards,

How do you measure size?

I just purchased a MacBook Pro. We ordered a 15" 2.4 GHz Intel Core 2 Duo, 2 GB RAM, and just received it in the mail.
It looked small to me so I measured the comp. witdth wise and it was only 13". I was telling someone about it tonight and they said to measure a computer you measure diagonally. Is that the correct way to measure a computer?
Also how do you check to make sure it is the 2.4 GHz?
I hope someone can help me.
Thanks!

Welcome to the Apple boards:
Size is always measured diagonally. If there were a way to get a larger number, they would use that
Regarding your speed and other important things, hold down the Option key and click on the little black apple on the top left of your screen. Select System Profiler and, Voila! there you go.
Everything about your computer is listed there - and more ....

How do you measure if a battery is failing faster than normal?

How can you tell if your battery is failing faster than normal or acceptable?
I bought 2 batteries with my G4 Powerbook 2 years ago. One now gives me an hour of battery life, and one 1.5 hours. This seems very low considering it's only 1 year of use per battery. Apple Care only asks about how long the battery has been owned... never how much it has been used, number of cycles, amps, etc.
Battery Information:
BATTERY #1
Full Charge Capacity (mAh): 2703
Remaining Capacity (mAh): 2170
Amperage (mA): 637
Voltage (mV): 12522
Cycle Count: 190
BATTERY #2:
Full Charge Capacity (mAh): 3032
Remaining Capacity (mAh): 3027
Amperage (mA): 0
Voltage (mV): 12417
Cycle Count: 105
Compare these numbers with my brother's PowerBook G4, bought just a few months after mine:
My main battery has 209 cycles and a capacity of 3686 mAh. My secondary has only 29 cycles and a capacity of 4400 mAh.
why does he have 3686 mAh after 209 cycles, and my bettery has 2703 after 190 cycles? Is there some way to tell if this is "inappropriate" loss of power?
Thanks

I did do several things wrong (that I only found out about now):
1. I left the computer plugged into AC
2. I stored whichever battery was not in use full, rather than half full
But I did callibrate regularly (if only by necessity).
I still think 1.5 hours at 2 years is not very good if you are using two batteries (that's really only one year each).
However, I called AppleCare, and I was told they will only consider a battery if it has been owned for under a year, and has less than one hour of life at best. That still seems extremely low to me (I'd be upset if I had 1 hour at 1 year on my only battery), but such is life. I think the moral of the story is that it would help to give instructions about battery care with the computer, and don't buy an extra battery unless you really need it.

How to dispatch custom events from an item renderer used for Datagrid Column

Hi,
I am using an Item Renderer for a Data Grid Column and in that mxml, I am dispatching a custom event with data.
But the main mxml which has the DataGrid is not able to resolve the event. How can I solve this?
Thanks

Hi,
This is the constructor for Event.
public function Event(type:String, bubbles:Boolean = false, cancelable:Boolean = false)
When you created your custom event after extending from Event, for the parent container receives the event, the bubbles property must be set to true.
Please check if you have done so. That should solve the problem. Let me know if it doesn't.

How to overlap datagrid colums line with item renderer

Hello guys I been stuck for a few days now and I'm wondering if there is a better way to do this.
I put an item renderer on a column of the datagrid. The renderer basically expands the column height and shows some controls.
Im using a border container as the container that is holding the items in the grid. However what I would like to do is make the border container as big as the grid with a plus sign button. and then basically hide that rows vertical grid lines.
i tried setting the depth eventhought i understant this is not a spark grid i though it should work but it does not. Any tip or direction would be greatly appreciated.
Miguel

ok i answered my own question. what i need to do is use the advance datagrid. Then set these properties.
<mx:AdvancedDataGrid defaultLeafIcon="{null}"
                         folderClosedIcon="{null}"
                         folderOpenIcon="{null}"
                         disclosureClosedIcon="@Embed(source='assets/plusSign.png')"
                         disclosureOpenIcon="@Embed(source='assets/plusSign.png')">

How do you pass more than 3 items to another page via a Column Link?

I know this is a simple question, but I don't see it covered in the manual.
I have a report on page 1, when the user clicks on a column link, I'd like to pass 4 items to the page that is called.
The Column Link area allows you to specify 3 items. How do people normally accomplish this?
Do you somehow use page zero? Do you use Application Items for this purpose?
Also, can someone recommend a good APEX book to supplement the manuals?
Thanks

hI
Oh Varad I didnt know this, Thanks for a new tip ;)
Just change the target to URL and enter a simple statement
in the URL section
f?p=&APP_ID.:50:&SESSION.:10:&DEBUG.::P50_item1,P50_item2,P50_item3,P50_item4:value1,#column_name2#,#column_name3#,#column_name4#
Use value when u know a fixed value to be passed
and column names on the same report can be passes by using #column_name#
Hope this helps
Thanks

How do you measure frequency using the onboard counter on PCMCIA 6024-E

I am using LABView 6.1 and NI-DAQ 7.2 with a SCXI-1000 chassis and a PCMCIA 6024-E on a laptop. I need to measure a frequency of about 3KHz and would like to do that using an 1180 direct through connector.
Firstly, should I see this 1180 in MAX like any other module?
And secondly, how do I use this 6024-E card to measure frequency? Which pins are supposed to be used on it to measure, and will I see the counter run in the test window in MAX according to the frequency measured?
I know NI also have a frequency module for the SCXI chassis. So lastly, will it be better to use that, rather than measure directly off the 6024-E?
Any help, advise or comments will be greatly appreciated!
Thanks!

Hello,
I think I can help out with some of your questions. First, the 1180 module won�t show up in MAX since it is really just a feedthrough cable which allows you access to your unused signals from the DAQ card.
You definitely can measure frequency using your 6024E. An example installs with NI-DAQ 7.2 which shows how to accomplish this. To access this example go to the LabVIEW start up screen and hit the Find Example button. When the Example Finder opens up browse to the following location: Hardware Input and Output -> DAQ -> Counters -> DAQ-STC -> Measure Frequency (DAQ-STC).vi
This example measures frequency and has a connection diagram on the front panel. The documentation for the example can be accessed by going to File -> VI properties -> Document
ation, after you have opened the VI.
You are correct that we offer a frequency input module for SCXI (SCXI-1126). This module would be useful if your input voltages are non-TTL, or if you need to measure more than one channel of frequency signals. This module has an input range of +/- 250Vrms and 8 input channels.
I hope this helps! Let me know if there is anything I can help with or clarify.

How do you get to display checkbox items in list or detail layouts?

Hi,
I have searched everyhwere for what I felt would be standard stuff in web apps, now lost a day to it!
None of the online videos/knowledge base articles or this forum seem to cover it but I can't believe you wouldn't be able to do it.
If I have created checkbox fields in my web apps how do I get them to display in the main templates (details and list) as list items, ul, ol or dl or anything else other than raw output?
How do I wrap the nessersary html around the values? Jquery for now I guess or is there some hidden liquid layout or tag parameter/value I don't know of?
And whilst I'm on it is my only option to not show or show content based on a boolean true/false value to do it through jquery/css?
Help appreciated, so desperate now!
Regards
Bangers

Hi Mary,
Thanks for the help. I saw that somewhere though Adobe's making this forum nice and tricky to find anything! Relied on google caching for most useful stuff I've found to bybass the redirect to the first forum page.
I needed it to wrap around the items so came up with this:
<script type="text/javascript">
     $(document).ready(function () {
     // Populate a dl with checkbox items or choose any other html to wrap around items
         var checkItems="{tag_checkboxItems}";
         $('#dlID').html('<dt>Items List Title</dt><dd>'+checkItems.split(",").join("</dd><dd>")+'</dd>');
          // #dlID can be anything but identifys the html element that you setup to contain your list of items in my case it was a dl with id #dlID
</script>
If there is a better SEO method to do this please let me know.
Frankly I've been amazed that web apps don't really support conditional statments and there is little to no information on achieving it through jquery (my first projects have been fairly basic)...roll on fluild layouts I guess.
Failing that maybe Adobe could produce something in the knowledge base or videos which really do cover more advanced implementaion of web apps. I doubt anyone using web apps or having had experience of other CMS would really consider showing or hiding content based on boolean results or looping to create lists all that advanced, it's more a fundemental function of a CMS.
P.S Thanks again to both of you.

How do you add a combo box item in Forte?

Okay how do I add items to a JComboBox using the Forte form editor.

String stuff = new String{"1", "2", "3", "4" };
I think you ment to make stuff an array of String.
In component inspector under Code Gneration
select post creation, select the ... box and type in
new JComboBox(stuff); or = new JComboBox(stuff);
might have to put the equal sign in there I forgetI did this and I am not getting any items dropped down.
