How to make a label refresh when it is used as a counter in a loop?

Hello

I would like to have a label or any other control refreshes and displays some kind of progress in a loop like this:

for(var z:int=0; z<Something.length; z++) {
 // Do some processing ...
 
 // Display the progress ...
 lblProgress.text = "Progress: " + z.toString() + " / " + Something.length.toString();
 lblProgress.validateNow();
}

The problem I have is that the update happened once at the end of the processing loop.  How could force the system to display each loop?

Thank you.

See Event.ENTER_FRAME

  • How to make a label (javafx) to display the current time dynamically?

    Hi all

    How to make a label (javafx) to display the current time dynamically?

    I have not found a Type of event related to the time in javafx API.

    Please give me some suggestions. Thank you!

    There are lots of examples of JavaFX clocks available, for example https://gist.github.com/jewelsea/3388637 or http://blog.crisp.se/2012/08/09/perlundholm/an-analog-clock-in-javafx

    For a simple label displaying the time, the simplest thing is to create a Timeline with duration 1 second and the number of indefinite cycle, which triggers an event handler that updates the label:

    final Label clock = new Label();
    final DateFormat format = DateFormat.getInstance();
    final Timeline timeline = new Timeline(new KeyFrame(Duration.seconds(1), new EventHandler() {
         @Override
         public void handle(ActionEvent event) {
              final Calendar cal = Calendar.getInstance();
              clock.setText(format.format(cal.getTime());
         }
    });
    timeline.setCycleCount(Animation.INDEFINITE);
    timeline.play();
    

    (If you use Java 8, use the new time API, which is much more pleasant than calendar.)

    Step 2: If the problem is solved in SafeMode with networking, then I suggest to perform clean boot and remove the program that is causing the problem.

  • How to make a Player audio html5 can be used since a .psd

    Let's say I have a .psd of an audio player model. How can I do that in something I can use as a Player audio html5 that I can put in my site?

    Tutorials, videos, tips, links to all sites welcome!

    My advice would be to dissect an existing audio player to see how its code. For example, the Wimpy Player skins are created with a LOT of CSS code and only has very few images.  For reference, look at online skin clothing Wimpy and this link: http://webdesign.tutsplus.com/tutorials/create-a-customized-html5-audio-player--webdesign-7081

  • How to make the data refresh

    Hello

    I have to update our database of production of a warehouse. There are a number of tables to be refreshed.

    Now, I can not have materialized views makes additional updates since the warehouse tables have no newspapers mview on them. Then I go to updates of the complete table. So I create a temp tables, freshen up first and then post it in the production tables. I use temporary tables instead of refreshing production tables directly on the remote tables to reduce the refresh time of the production tables. The code example below.
    begin
    execute immediate 'create table table1_temp as select * from remote_tab@dblink';
    execute immediate 'drop table prod_table1';
    execute immediate 'create table prod_table1 as select * from table1_temp';
    execute immediate 'drop table table1_temp';
    Now, I read it somewhere that the temporary tables can fragment the disk space and adversely affect the performance of DB over time.

    Could you please suggest alternative strategies for this task and their advantages and disadvantages?

    Thank you
    CJM

    If you want to control the update with the logic and processing that can indeed be done using a materialized view, you can consider the following.

    -Use a DEC (create Table as Select) to create a new table.
    -Add the clues necessary to the new table (and provide subsidies are necessary).
    -Remove the existing production table (or rename).
    -Rename the new table as the production table.

    This approach works well when the last step is an exchange of partition - penetrating the new content of the table to partition table and exit the old content.

    The thing to remember is to keep it simple (KISS) and not reinvent the wheel. Oracle has a rich set of features and offers great flexibility.

  • How to make a transparent background when editing

    Hello

    I was wondering how to get a transparent background in flash.  I did a lot of research and have seen many forums, but I don't want my file to export to HTML.  Is it possible to have a transparent background, with some having to have a HTML file?  I try this enter into Camtasia Studio, but there is a white rectangle behind the animation, blocking all the rest.

    Thank you

    Orion31

    You export a video to enter in Camtasia? If, therefore, in the export options video there is a checkbox to say to ignore the color of the scene and to generate an alpha channel. Don't say to compress the video in Adobe Media Encoder, just take the MOV file in Camtasia.

    If you say that Camtasia supports importing of SWF files, then it would be Camtasia to make the background transparent.

  • How to make an advanced search when you use adobe reader software in a firefox window?

    I used to be able to do an advanced search in a tab in firefox, but when I updated firefox to version 17.x 33.0 version, the interface has changed and I cannot figure out how to do more.

    Finally, I realized that a simple search can be made with Ctrl-F, but I would get the Advanced Search Panel.
    When I use internet explorer, it has a binoculars icon that will open the advanced search. Firefox doesn't have this.

    In addition, Firefox put up their own PDF Viewer with version 19.0; It's no longer using the Adobe Reader plugin.  See http://helpx.adobe.com/acrobat/kb/pdf-browser-plugin-configuration.html
