ListField images update

Hello

I have a ListField, who I am complete with JSON data analyzed a HTTPConnection. Each line of this ListField has an image. I need to get each image on the server (I have the url in the data analyzed) so I need to establish an additional connection in each line for this. Who should be the right method to do this? I guess I should NEVER try to retrieve the images in the same invokeLater() method which is holdind the thread of events (and creating the ListField with data retrieved from the server and by attaching it to the screen), otherwise, this may cause my app go very slowly.

Any ideas? Thanks in advance!

"the entire ListField" is actually only a reference to a. It's actually how to Java - only non-object privitives (such as int, char, long, etc.) are passed around in its entirety. The rest are represented and accessed through references. So don't worry - you don't carry huge amounts of memory wire to wire with your references ListField .

Overall, you have two models of design working here - producer-consumer and publication / subscription. Your ListField is a producer of "download requests", which are consumed - one - by the download thread. However, the ListField subscribed (by providing his reference and, say, the line index, within the "download request") to the "full download" events that are published by the download thread.

Moreover, you don't need nets more for it - the UI Thread (also called wire event, see ""that is the event Thread?"for reference") and the download Thread are everything you need here.

If you want any kind of "load-balancing", however, you can create a download thread dispatcher and two or more threads of work for download.

  • Pass data to Image update Subvi VI main

    I try to get under VI containing a for loop to pass data to an indicator on the main VI update. I followed this explanation...

    http://digital.NI.com/public.nsf/allkb/0F4EA104660C0AF38625726F0069B27E

    .. .and am able reproduce the example with a digital command, but I was not able to extend the example to an indicator of image output. I suspect that I use the control bad, Refnum reference or property. Can anyone suggest corrections?

    Details:
    I use a control reference [line] to a [Picture] indicator of my main VI [Center of manufacturing] to the Subvi [SUB mask display].

    I placed a Refnum control on the front of the sub - VI, he linked to a property on the block schema node, selected the property "Value" and hooked up the output of the image of a VI IMAQ to this property.

    If 'Run of Images' on the sub VI is set to FALSE, a static image 'test0.jpg' must be returned to the main VI. If 'Run Images' is set to TRUE, a loop is supposed to pass 'test0.jpg', "test1.jpg", etc. to the main VI at regular intervals. Instead, the indicator Image is empty.

    Hi MaryamAli,

    I think you are doing everything correctly but you are having your image inside the Subvi so the will of image ever seen in the main VI. Try to remove the IMAQ dispose VI in your TRUE and FALSE cases and see if it works.

  • Point ListField not updated correctly

    Hello world. I'm not very old in BB platform. This is my first post. Hopefully I'll get the key to my answer here.

    I developed an application where on one screen, I have a Listfied.The of the listfield rows are populated by the data of a vector. The line contains a single image to the left, two texts in the centre and two images on the right. Everything is fine until now. Now my requirement is that rather than displaying all 30 points only once, I need to implement pagination and displays 10 items by each shot.

    When the listfield screen comes for the first time, all of the 10 items are displayed. Basically, I have developed a next button and perform the action reqd. I can see that the contents of the vector is added successfully with the help of the print statement. But when he gets only the first element which is added gets displayed in the rows of the listfield and the rest of the elements. I tried with only two elements, image and text, but watever I add first to the TableRowManger (our own class manager) only this element gets dispalyed while I do pagination. Everything is added after that which is not displayed.

    I tried to call invalidate() on listfield instance, but without success. Why only the first element is displayed and not the rest, while I clearly see that the contents of the vector is added to the TableRowManager successfully. I'm scrathing my head with two heads, if I can get help from you all, I'll be very grateful. Thanks in advance.

    drawListRow is the reminder of the draw.

  • Linked clone, pool Non-persistent, Image update?

    Is it possible to update an image of non-persistent pool? I know it's not like a persistent pool where you can update the image, then recompose. But I thought that I might be able to go through the Wizard Setup again and choose my new snapshot and hit finish. But he has not updated one of my virtual desktops.

    Is it possible to update a non-persistent pool clone related? If so how can I go about it?

    If you point the new snapshot of the pool and then remove the existing virtual machine, it will create the new virtual machine based on the new snapshot.

  • How to get the PS5 to smart an external tiff image update

    I want to originally create text and add effects to it.  But as I add effects or, especially, scaling it, I find that I have to go back and change the image of the text (lines more wide characters, change the proportions... etc.

    So I imported my text in the form of intelligent image and began working on it - but when I went and edit original, the changes were not reflected - I closed the document that I was

    work on and re-opened, it, just to be sure - maybe, it has not detected the file had been changed.  No difference.

    It seems he makes a copy separate from my original and uses this and the only way to update, is to remove an old imported smart layer and add a new and reapply all the layer effects to the new layer (or transfer of the former more later before deleting).

    Seems a bit awkward... Should not the smart picture let me understand something

    externally, and as it is imported, it is important a bitmap of the current content of size for the 'frame' appropriate for the imported layer?

    Just another question - can not just copy the layer effects - have to reapply a cropping or resizing made you in the smart image (assuming that the layer can take a zoom level and a mask - maybe he can't do it anymore?)... Since you can warp, so I assume that (remember reading in aid of layer effects applied to smart objects have been disabled while you distorted layers, or something like that...)...

    Is this possible?  Or how one does include dynamic content in an image when editing (NOT at the time of the DISPLAY - this is not HTML!  ;-)) .....

    Thank you

    -linda


    Change the original file you placed will have no effect on the smart object - content is embeded, not linked to an external file.

    Double-click on the smart object layer to open the document of the child for the edition.

  • How can I force image update sequences?

    I use first composite various sequences of images in one program 3D, Blender.  Several times I export a preliminary version of Blender, import the sequence to first place in the time line, so I find I want to make some changes in a blender and make a new made some executives.  Images that I have made a new, first update only some of them.

    I did a test where I got a new made a section with a different background color to the scene.  In the first three first executives set to date, then the fourth was the old image, 5th and 6th are new, 7th was old, 8th and 9th were new, and so forth.  He did for any updated image sequence, using a combination of old and new frameworks.

    I did the above test three times.  The first time I saw mixed frames, the second time that all imported fine, the third time I got the mixed frames again.

    If I restart the first, then it goes through the screen 'media pending' for all my media and then shows the correct update management, but it would be embarrassing to have to restart the creation each time I want to see my new frameworks.

    I use first Pro CS5.0.3, on a 2.66 Ghz Quad-Core Mac Pro with 8 GB of RAM.  The files are located on an eSATA RAID 5 array.

    Is there a way I can force the first to update the frames in image sequences?

    Does anyone else have these problems?  What do you do when dealing with many sequences of images that you frequently update?

    Thanks for any help.

    Is there a way I can force the first to update the frames in image sequences?

    Three choices.
    1. do not leave the first opened during rendering in another
    request (it's what I do).
    Overwritten files will update when you first.

    2. right click your picture in the project window sequence,
    Select "make Offline... > Media files remain on the disk > OK.»
    Then, right-click in your sequence of image in the project window,
    Select "Media link...".

    3. close and reopen your project without leaving the first.
    File > close (Ctrl > W), then re - open the same project.

  • Image updated periodically

    Hi all!

    I am writing a quick web application to display a set of images from a server. The images on the server will be updated periodically, but retain the same name.

    The flex application needs to regularly recharge the images from the server. I tried to write a timer in AS 3.0 to call Image.load, but it didn't update the images. Maybe because they are put in cache?

    Here is what I tried, but what is the best way to do this in flex? I'm very new to flex, but not of actionscript.

  • ListField: RENDERER updates only the top line

    Hey all,.

    Calling for first time, long time listener. I cut my teeth on BB dev and have hit a snag. I created a ListField which takes an array of custom RowObjects that includes not only the table that makes up the line, but both the properties of style (background color, text color).

    My 2 questions are the only the first line is its background color and the rest are by default. None get the color of the text. It seems that the rendering engine is only called once, bouncing absolutely me.

    The second problem is that I can't scroll horizontally to view additional columns that are off-screen.

    Yes, but it must not necessarily be 'this '. It can be any other object that you did in your implementation.

  • Predownload Image update for the controller

    I have a question for someone who has experiece with predownload function.

    I'm trying to minimize my reboot of the WLC.
    Is it possible to download the AIR-WLC4400-K9-7-0-220-0.aes AND the AIR-WLC4400-K9-7-0-220-0-ER.aes for controller and restarting only once?

    {make changes according to the comment of Wesley. He's right

    No, you will need to restart after the installation of the daughter of ER. Do not install both files at the same time.

    You can install the file .aes on the controller of two first and then use the command of permutation and perform a simultaneous restart.

    1. install AIR-WLC-7-0-220, 0 aes on both controllers (not restart)

    2 see the boot (your new image is the main)

    Change here: boot Config backup (* this is necessary if we use the command swap)

    config 3 ap primary predownload image all the

    Additional notes:

    The access point compares his running image with the image running on the controller. If the versions match, access point joins the controller.

    If the versions do not match, the access point compares the version of the backup image, and if they match, the access point swaps main and backup images and recharging and later joined the controller.

  • Muse freezes when updating of the properties of the image.

    When I right-click on an image in the lightroom Gallery widget and get the image properties dialogue box, sometimes Muse freezes and I can't close the dialog box, which means I can't close the Muse.  It does not seem to be any rhyme or reason when it freezes.  Sometimes just after a few properties of the image update, other times after more than a dozen.  It doesn't matter if I'm changing the formats of office, tablet or phone.  The only solution is Force Quit Muse.

  • How to make the images uploaded to update in design mode?

    PCOC
    I can create a page with local images and their replacement updates fine in design mode.

    How can I replace the images uploaded to in Design view, although both have been modified locally and on the site? Display live shows correct, but design view is not updated.

    The previous image always seems to be in sight unless I have replace it with its new local image (self-titled) and then change the link to account for his site link.

    Behavior of buggy which seems to have been put in place for a couple releases now.

    TIA

    DW has always had problems with the display of the images remotely located in Design view, the terrible workaround for it is to close and reopen the DW for the external image update is displayed correctly.

    However, it should not have any problem with changes to local images. Who should view as soon as the local file is modified.

    Work on one Site?

I used HPDM 4.5 to capture the final image, and it works very well to expel this image to any t510 race ThinPro 4 already. However, if I try to send the same hardware, running HP Smart zero Core, it fails with the error below. I want to be able to send this image to all t510 connected to the HPDM or running the other operating system. Someone knows what's the problem?

    Error message (task not supported), sounds like agent on Smart zero is not up-to-date. If you don't the have not already done so, wil you update the agent on the t510 Smart zero prior to sending the image update task.

  • Do not load, stop, "update needed"

    Hello

    My MBP early 2011 has been acting for the past two days. He started does not load, the LED does not illuminate, and the computer would not recognize to be plugged. Then he started closing in the medium used. He did twice in the last hour. When it restarts I get the attached image "update needed" on my login screen. I tried to do an SMC update addressing battery problems, but that did not work. I am located outside of the country for the next days 50 so all advice that could save my computer until I can get to the Genius Bar would be much appreciated.

    Thanks for any help!

    You have the early installation of Snow Leopard original supplied with your 2011 MBP diskettes?

    What is the current OS x you have installed?

    Ciao.
