Anyone know how to fill an array faster?

Hey everyone,
I created a program which displays an intensity graph, as well as a histogram of the intensity values on a 1024x1024 chip (X-Y dimension). Currently, the program works fine, but the histogram takes FOREVER to complete, and I was wondering if there's a way to increase the speed of this while including all of the 1024x1024=1048576 data points. Thanks!

Please attach the actual VI. A code image is pretty useless.
Keep the histogram in a shift register as a 1D array of a sufficient number of elements. In any case, try to autonidex over the 2D array using two stacked FOR loops and built the histogram using the inplace element structure and using the value (Or something derived from it) as index. How many bins do you want? Your values are U16, so using a histogram with 2^16 elements is not out of the question.
Also don't use express VIs and don't update the graph with every iteration of the inner loop. Indicators belong after the FOR loops.
Your current shift registers are useless. You get the same value from the iteration terminal, right?
Why do you reset the histogram at the last iteration of the outer loop, throwing away all data processed until then????

Anyone know how to output an XML file from ABAP to a non sapgui location?

I have a program that creates XML and then outputs a file via CALL METHOD cl_gui_frontend_services=>gui_download. But now I want to execute the program in background mode and therefore I need to be able to output that XML to a NON sapgui file location. Current code creates the XML to an internal table which is binary then the gui_download method converts that to output XML. . Does anyone know how I can change the code to either a) output the XML to an internal table which can be output via, say, a TRANSFER command..or, b) output the created binary table of XML to a NON sapgui file location?
Excerpts from current code are as follows:
first the XML is created (to the binary file)
      Creating a ixml factory
l_ixml = cl_ixml=>create( ).
      Creating the dom object model
l_document = l_ixml->create_document( ).
      Fill root node with value XML
l_element_xml = l_document->create_simple_element(
              name = 'XML'
              parent = l_document ).
      Create tag 'HEADER' as child of 'XML'
l_element_header = l_document->create_simple_element(
              name = 'HEADER'
              parent = l_element_xml ).
header information about the file and general data about the fleet follows
l_value = c_fleet_import.
l_element_dummy = l_document->create_simple_element(
            name = 'TYPE'
            value = l_value
            parent = l_element_header ).
etc.......
then the xml is connected to the stream factory and rendered
Creating a stream factory
l_streamfactory = l_ixml->create_stream_factory( ).
Connect internal XML table to stream factory
l_ostream = l_streamfactory->create_ostream_itable( table = l_xml_table ).
Rendering the document
l_renderer = l_ixml->create_renderer( ostream = l_ostream
                                        document = l_document ).
l_rc = l_renderer->render( ).
Saving the XML document
l_xml_size = l_ostream->get_num_written_raw( ).
and then output to the file
IF sy-subrc = 0.
    CALL METHOD cl_gui_frontend_services=>gui_download
       EXPORTING
         bin_filesize = l_xml_size
        filename     = 'g:\sapdms\BSCC-DEV\EFPAC XML Files\ALL.xml'
       filename     = '/TRICK/727/OUT/ZEFP/EFPAC.XML' "doesnt work with sap gui
         filetype     = 'BIN'
       CHANGING
         data_tab     = l_xml_table
       EXCEPTIONS
         OTHERS       = 24.
as implied by the comments the method above will successfully output the XML file to the g:drive but will not output to /TRICK/ location, which is where I need it to go in a background mode run.
This is a problem which has defeated all our local expertise and I would appreciate any help given... Barry Jones

Try this code below:
data l_xml_table2 type table of xml_line with header line.
W_filename - This is a Path.
if w_filename(02) = '
    open dataset w_filename for output in binary mode.
    if sy-subrc = 0.
      l_xml_table2[] = l_xml_table[].
      loop at l_xml_table2.
        transfer l_xml_table2 to w_filename.
      endloop.
    endif.
    close dataset w_filename.
else.
    call method cl_gui_frontend_services=>gui_download
      exporting
        bin_filesize = l_xml_size
        filename     = w_filename
        filetype     = 'BIN'
      changing
        data_tab     = l_xml_table
      exceptions
        others       = 24.
    if sy-subrc <> 0.
      message id sy-msgid type sy-msgty number sy-msgno
                 with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    endif.

Does anyone know how to upgrade from 4.1 to 4.3 ios?

After being tricked by the fast talking smoothy helper at Apple store in London to buy a micky mouse ipodtouch (fourth generation) two years ago I am stuck at ios 4.1 and find that all the useful applications need 4.3 or more. So I went to the trouble of letting the macbook stay open all night to load yet another micky mouse version of itunes so that I can upload the more recent version of ios and now (since I don't want to continually have a lot of rubbish on the ipod I disabled the automatic sync "feature") I can only go round in circles whereby the only real possibility left is to turn on the autosync feature. I have had messages like "your ipod will be completely erased if you proceed" and "do you wish to fiddle another few days with this nasty system, then click on continue" and so on.
Does anyone know how to upgrade from 4.1 to 4.3 ios?
That would be great (maybe) because otherwise I will toss this children's waste product on the floor and set up my HD camera to show how easy it is to smash the brightly lit screen into pieces and relieve myself of trash which Apple sell to unsuspecting gullible humans who believe that they are not being tricked by such a nice company who produce shiny colourful gadgets which only work for a month or two before becoming 100% obsolete.
Great to hear from those who have wasted many months of their lives and discovered how to trick the system into doing a simple update operation!
I am insulted by the tricks that fool many and that apple pretend are "necessary".

Illaass, your help is amazing - miles better than anyone working in this part of the world who is paid - and you do this for free - because, like me, you LOVE to help people!
BUT, as I said above -
1. There is nothing "mobile" under Application Support. For whatever reason.
2. Devious - that Apple has set up iPod to not show in Finder - a red herring and sign that corruption is visible.
I will try iFunBox next and it sounds like they provide this for the more serious users but use a trivial name to excuse further strangeness.
After
There are purchased items on the iPod that have not been transferred to your iTunes library. You should transfer these items to your iTunes library before updating the iPod. Are you sure you want to continue?
I get
Updating to iOS 6.1.5 will backup and restore the apps, media, contacts, notes, and settings on your iPod touch.
Please do not interrupt the update, which may take an hour or longer to complete.
Cancel          Update
And then I wait for hours to arrive at the above mentioned
Backing up iPod   \\\\\\\\\\\\\\\\\\\\\\\\\ Stop
and then as above
An error occurred while backing up this iPod (0xE8000084). Would you like to continue to update this iPod?
Continuing will result in the loss of all contents on this iPod.
Cancel                Continue
and so we are back to where we always land - the user is left in the Apple designed sabotage situation which annoyed me so much initially.
"Most users will give up at this point, loose all the data or buy yet another disposable from Apple. Less than 3% will work their way to this site and 90% of the 3% will leave the iPod to gather dust in the hope that someone will help later. In all, Apple gains, since people blame themselves for "mistakes" which Apple programmed to throw out users who do not take the 100% Apple path. But Illaass and myself still play the game of "trying to fix" something which Apple don't allow." was the comment which I was going to write but decided against it, adding no value to the conversation other than explaining one reality which we all hoped could be wrong but which I thought to have a very high chance of being closer to the truth.
Apologies for my doubts towards the integrity of the creators.

Recheck: Under Application Support "mobilesync" folder has appeared (MobileMeSyncClient has also appeared [while again trying to update iPod] with zero size) - Good news, a Backup file is there, but it is only 3GB while my iPod has 32GB and is close to full (800MB free space).

The iPod could not be restored. An unknown error occurred (9).
More Infomation    OK
So it looks like I may have lost all the important pictures documenting various items all around Europe for the last two years - luckily I moved a year ago from the iPod toy camera to a Panasonic real camera with SD card which can be read on any computer. Hence important items lost may only be older than one year rather than the most recent items.
Glad I have changed to Panasonic since they don't try to screw you when you don't use their system.
I will now check the "more information" rather than just click on "OK" since I am of the 3% who "don't accept cr*p".
For full information I quote that the iPod now shows a screen with a USB ikon, an upward arrow and an iTunes ikon (all micky mouse language which reduces transparant, clear and technical discussion and thus covers the trail of "where things went wrong").
The iPod is still attached to the computer but the above MMTALK may mean that the iPod should be attached via USB to the mac. I record much of this activity on Video to be able to later prove EXACTLY what occurred, rather than having to rely on screenshots and opinions. We are after all dealing with important items which may later be required to be shown in court, as evidence against fraudsters.
The "More Information" link leads to
Resolve iOS update and restore errors in iTunes
which I have already seen before.
I clicked on OK and a help screen (unnamed as ever because no one like myself demanded that the help screens be named for later discussion) arrived:

while copying this into this message the computer began to start up Final Cut Pro and this was cancelled, then iTunes came up with a message:

And I presume the earlier message about helping Apple is gone because I keep getting interrupted by this message called
iTunes has detected an iPod in recovery mode. You must restore this iPod before it can be used with iTunes.
ok
it has appeared now at least six times interferring with anything else I do. Each time I try to write, this message appears and blocks, but only when I write. I tried to do a carriage return and the message appeared taking the carriage return as acceptance of the OK in the
iTunes has detected an iPod in recovery mode. You must restore this iPod before it can be used with iTunes.
ok
Message. But since I have not removed the USB and keep returning to this message I am able to write for a few seconds (now 30 seconds or more) and the message remains on the screen but not blocking this conversation. It appears to be random but in fact as you can later see from the video, it is not reappearing each periodic number of seconds but as I reach a new comment.
I will try to close iTunes so that this can be stopped (I clicked on OK and it appeared another few times, each time I clicked on ok and now it has left me in peace to write here although iTunes is still not yet closed).
Difficult to log down all the strange behaviour but I think you can get the gist of what is going on.
2014 01 12 12 49 27
Should I remove the iPod and stop iTunes? I have a nasty feeling turning to indifference since I have video footage which will verify all the above in a court of law if later required. The truth must always win over any devious attempts at forcing people to do things they don't want to ;-)

Does anyone know how to filter all items in an XMLListCollection?

I have a tree with the following structure.
<node>
<node1>
<node2>
<node3 />
<node4 />
<node5 />
</node2>
</node1>
</node>
I need to be able to filter on node 3, 4 and 5 and then after
the filter if they don't exist get rid of node 2 level and then do
another filter function to check if node 2 level is there and if
not.. then filter out node 1 level. Basically this is a bottom up
filter. In Flas 2.0 I would filter out the base level by deleting
nodes.. and then run through the next level and check if they had
any children or not.. if they didn't then I would delete them.. and
then I would repeat the step for the last level.
Does anyone know how to do this without having to remove the
items from the collection.. basically perform a filter rather then
a delete. I know the filter function only returns the first element
of the xml struct.. which is annoying. If anyone can help me out I
would sure appreciate it?
Thanks

I guess the filtering on a tree only passes in the root
nodes... This is hugely lame on Flex's part. I basically had to
make my own functions to delete the nodes dynamically.
Remember this only works on an array item which is dynamic.
delete list
To make this work I have a main TreeCollection... and from
that I made a copy. Treecollection.copy() and deletes stuff from
the copied struct. After the deletions were done I then assigned
the copy to the MyTree.dataprovider = copy.

There is a transparent color over my file in muse whenever I'm editing the file, does anyone know how to remove this?

Here's a screenshot. I've tried everything to make it go away, including changing the browser fill color, but this just wont change. It does disappear when I preview the site online, though. Does anyone know how to remove this color? Thank you in advance!

You need to ask Apple to reset your security questions. To do this, click here and pick a method; if that page doesn't list one for your country or you're unable to call, fill out and submit this form.

Reset Security Questions
Frequently asked questions about Apple ID
Manage My Apple ID
Or you can email iTunes Support at iTunes Store Support.
If all else fails:
1. Go to: Apple Express Lane;
2. Under Product Categories choose iTunes;
3. Then choose iTunes Store;
4. Then choose Account Management;
5. Now choose iTunes Store Security and answer the bullet questions, then click
      Continue;
6. Sign in with your Apple ID and press Continue;
7. Under Contact Options fill out the information and advise iTunes that you would
      like your security/challenge questions reset;
8. Click Send/Continue.
You should get a response within 24 hours by email.
In the event you are unsuccessful then contact AppleCare - Contacting Apple for support and service.
Another user had success doing the following:
I got some help from an apple assistant on the phone. It is kind of round about way to get in.
Here is what he said to do and it is working for me...
a. on the device that is asking you for the security questions go to "settings", > "store" >
      tap the Apple ID and choose view"Apple ID" and sign in.
b. Tap on payment information and add a credit/debit card of your preference then select
      "done", in the upper right corner
c. sign out and back into iTunes on the device by going to "settings"> "store" > tap the
      Apple ID and choose "sign-out" > Tap "sign -in" > "use existing Apple ID" and you
      should be asked to verify your security code for the credit /debit card and NOT the
      security questions.
d. At this time you can remove the card by going back in to edit the payment info and
      selecting "none" as the card type then saving the changes by selecting "done". You
      should now be able to use your iTunes store credit without answering the security
      questions.
It's working for me ...I just have to put in my 3 digit security pin from the credit card I am using.
Good Luck friends!

Does anyone know how to get a hold of someone in charge of QA

Customer support is dire! I have spent long hours dealing with costumers service <whose only modes of help are sending me out to buy something new or provide me with a hyperlink to help page that was two clicks away anyway> Between thier lack of knowledge and SARCASTIC JABS it's amazing that I have retained my sanity. I won't go into details but I'll catch you up. 4 sessions in live chat with LOOOONG delay in between responses and I can not make recovery disc, my phono jack does not function properly, my system can not communicate MTP <you know, what you use to fill your ipod, and I kid you not there is a fan LITERALLY RATTLING AROUND inside my 2 month old notebook. So what do I do? I exhaustively seach for away to get a hold of customer service, and all I can find are blogs about how HP costumer service sucks. Bear in mind that I did not put suck into my search engine. I put "HP QA and HP customer service" into google and what returned was BLOGS ABOUT HOW HP CUSTOMER SERVICE SUCKS. Those were the most relevant results in google. So I finally come to this forum and find a thread about..........you guessed it hp customer service sucking.....but oh no an HP moderator locked it down and provided a link to the page where one can obtain the very customer service that has been deemed insufficient by the very COMMUNITY that it is supposed to support. WE PAYED YOU PEOPLE! YOU ARE HERE FOR US NOT WE FOR YOU.

P.S.
This is on my Iphone 4 that i am using it on.

I accidentally deleted my iMovie off my mac, anyone know how to get it back because it came for free and is now 15 dollars to buy back??? pls help

i accidentally deleted my iMovie off my mac, anyone know how to get it back because it came for free and is now 15 dollars to buy back??? pls help

If you mean you accidentally removed the icon for iMovie from the Dock (the array of icons at the bottom of the window), you can add it back easily.
Open the Applications folder (if you open it from the Dock you may then need to click the Open in Finder icon), locate the iMovie program.
Drag the icon for iMovie down to the Dock, somewhere between the icon for Finder and the dashed line toward the right.
Wait for the icons at that spot to move aside, then drop it in.

Does anyone know how to achieve this in Photoshop? Any help is appreciated, thanks.

Hello,
I'm relatively new to Photoshop so if you know how to do this, please explain by telling me where I click. E.g. File>Open
Does anyone know how I would achieve this exact effect in Photoshop in the image above (without the circular logo)? The 2 light blue type of effects, one at the top of the image, the one at the bottom of the image. I don't know how to achieve this effect, please show me if you know how. I'm using Photoshop CS5.
I have looked through hundreds of tutorials, none provide me any clue as to how this is achieved.
Or does anyone know a tutorial on how this effect is achieved?
Thank you for your help.

Yes, it would have been faster and more constructive to point out exactly where to find information rather than scold you.
Check out the Option bar that one gets under the Menu bar. If it is not showing, go to windows>Options.
More info: http://helpx.adobe.com/photoshop/using/tools.html#using_the_options_bar
If you select the brush tool, you will notice a flow value, that you can lower; and a Mode drop down list.

Help!!!!! anyone know how to change a Double to an int??

Help!!!!! anyone know how to change a Double to an int?? for use in an array[int].

I don't know why would you want to depend on a double value to build your array but programmatically just use plain old cast: i = (int) double_value;
Keep in mind though, the integer value will be truncated.

Hello - Does anyone know how I can color the middle of a two circle Venn Diagram in InDesign CS6?

Hello - Does anyone know how I can color the middle of a two circle Venn Diagram in InDesign CS6?

I essentially do what Ellis recommends, although I usually use a somewhat different method:
Draw two circles
Copy and paste in place
Select the topmost circles
Use Object -> Pathfinder -> Intersect, which creates the green object in Ellis' screenshot
Then grab the bottom-most circles and use Object -> Pathfinder -> Exclude Overlap
Lastly, with your Exclude Overlap circles still selected, use Release Compound Paths.
This has the same effect, but I don't love the anchor-points-and-scissors method myself. Many years ago I taught myself Illustrator with a flaky mouse on an irregular surface; it left me with a pathological hatred of tasks that require fiddly mouse-work. So I have keyboard shortcuts for all of the above, and can select all of the objects without having to very carefully mouse over a path. If you're fast with fiddly mouse-work, Ellis' method will probably work better for you than mine.

does anyone know how to get a white line across text like the USA basketball logo?

Draw the shape which is to be knocked out (a line in the example) in a layer above the logo. The colour doesn't matter because it will be made invisible.
Double-click in the space to the right of the layer's name in Layers panel to open its Layer Style window where advanced blending can be modified.
Set Fill Opacity to zero and Knockout to "Deep" or "Shallow" depending on whether the knockout should be limited to a containing Group.
