  How to extract information from the ovf file from a file of eggs by programming?

  Hello

  Please provide details:

  -On what OS you are programming (Linux, Windows,...)?

  -What programming or scripting language do you use?

  An EGG file is just a tarball of hard, .ovf and .mf files. The .ovf file is always the first. For example, on a Unix like operating system, this should be easy.

  For Windows, there are several options available to manage programmatically the tarballs. See for example http://www.codeproject.com/Articles/470999/tarlib-Windows-TAR-Library.

  And the ovf itself file is in XML format. For handling XML files are libraries available for literally every OS and programming language.

  Google is your friend.

  -Extract all data from a single file can be done via the tools - forms - more form Options - export data...

  -Extract some data from a single file will require a script to measure.

  -Extract all the data from multiple fields in a single file can be done via the tools - forms - more form Options - merge data files into spreadsheet...

  -Extraction of data from several files will require a script Custom Action, as I've written before.

• Question of feasibility: extract information from the fields to the PDF format

  I explore options to collect answers to a PDF form.  Fields of entries by the user are created, the user saves the form in PDF format and sends the return form.  The data entered by the user entered in the fields can be retrieved electronically?  I hate the very idea of renewing the data entered by the user to get it in electronic format.  For now, the question is ' is it possible - extract the entries by the user of the data in an electronic format?  If possible, then I can begin to explore the format, etc.

  It is worth noting since you stevat from the outset that it may be problematic to rely on email. Much better to send the form just like an HTML form. This needs a professional web programmer to provide web scripts, however. Also PDF forms do not work on some browsers and phones.

  It is easy to assume that the big trick is to design the form. But it's just the 10% above the water. Personally I wouldn't consider PDF forms more due to browser issues. Same Adobe move to a dynamic conversion to HTML forms then why don't no start with a? There is full form service providers that provide tools to collect and analyze. For example forms of Google - create and analyze surveys, free.

• How to raise an event from the arrayCollection collection?

  I'm passing data from a model to a view in the following files. It works fine, but I want to send a message on the screen when an arrayCollection collection is filled. I know that I could create a custom event, but I do not understand why the eventhandler I created will not work. Please tell me what I'm doing wrong.

  Thank you.

  You use "=" this is a reversal/replacement.  There is no chip

  assignment that will update.

  You could do

  model.databaseDataArrayCollection.source =

  Event.Result.Student.Task.source;

  That should translate into a CollectionEventKind.RESET in original HQ as it

  now a new set of data.

• How to extract information from tree logical structure using the PDF Library?

  How to extract information from tree logical structure using the PDF Library?

  Adobe's PDF Library has PDSEdit APIs to extract information of the logical structure of a tagged PDF file.

  But I couldn't find any example code to demonstrate the C API on PDSEdit layer.

  I google search using different keywords, find none.

  I contact datalogics (which gives me the evaluation of adobe PDF library copy), no code sample on APIs PDSEdit yet.

  Everyone knows any code example can demonstrate extract structure logic tree information PDSEdit APIs (in C/C++ or Java)

  from a tagged PDF file? And is there any sample to demonstrate that connects a tagged logical tree contained in the content stream?

  I thank very you much in advance!

  logicaltree

  Did you look at the code snippets in the SDK?  There are a bunch of samples to work with PDSEdit and structure/marking.

• Extract information from signature in VBA to a PDF file

  Hi all

  I need to extract information from signatures of PDF files in VBA (mainly the name of the signer and the date of signature. PDF files have several signatures inside them).

  So I have a few questions:

  -Are there an example somewhere to do such a thing?

  -I need Acrobat Pro for this? This is an important point because the code is supposed to be run on machines where ONLY Acrobat Reader is installed.

  -If the above is not possible, do you know a command line utility that would do the thing (and I could run from my VB code)

  Thank you for your help

  Emphyrio

  As already mentioned, you will need Adobe Acrobat Standard or Pro VB/JS bridge. If you want to make this work with just the free reader, you are limited to what you can do in JavaScript environment. Basically, this means that you must open the file in the player and then for example use a menu item to trigger functions to get information about signatures in your file. For example, this information may appear on a dialog box, and you would be able to copy & paste from this dialog (which means no VBA integration at all).

  Of course, you can use either Adobe PDF Library (licensed through Datalogics), or other 3rd party PDF frameworks/libraries. It's a site run by Adobe, you will understand that we cannot give you advice regarding 3rd party solutions that compete with the own Adobe solution.

• Extract information from a form of Muse

  I'm looking for a way to extract information from a muse of. The form is a type of query. ID like to be able to take emails all receipts and pull so that the names, email, zip code things like that and put it in a file pdf or something similar if it is a list of all that info. is there an option in adobe or a third party app that I could use?

  Not with the basic form. You need one of the plans Business Catalyst paid extra and advanced forms to process the data. In either case, it will be probably be much simpler and more profitable (as in totally free) to register directly for Surveymonkey, Polldaddy or ultimately OpenPetition.org. No point to try to reinvent the wheel.

• How to check whether or not the arraycollection collection is initialized

  Hi all

  I am bit new to use the collection arraycollection in flex. I'm having this particular scenario, where I get Server data in a table. So I have to check if the arracollection I created is initialized or not. If it is not initialized I need to initialize it or other wise, just add collection from table to table. Here is the code snippet

  currentTrajectory = new collection ArrayCollection (event.result as Array);

  var _multiTrajectoryEvent:MultiTrajectoriesEvent;

  _multiTrajectoryEvent = new MultiTrajectoriesEvent (MultiTrajectoriesEvent.DRAW_AUTO_TRAJ);

  If (!) (_multiTrajectoryEvent.trajectories.source is nothing))

  {

  _multiTrajectoryEvent.trajectories.addItem (currentTrajectory);

  }

  else

  {

  _multiTrajectoryEvent.trajectories = new ArrayCollection ([currentTrajectory]);

  }

  But unfortunately the above code does not work for me, because the arraycollection collection is not initialized first, there is no way of checking me if it is initialized later or not as the compiler gives me the error checking to null...

  Can any Walter suggest how can I check if the table collection is initialized or not?

  I would appreciate any suggestions and thouhgts for the same

  Thank you

  Akshay

  Sorry to say, but it's not the right approach...

  I'm abt don't know what is exactly done so I'll give a generic example...

  I have an ArrayCollection collection...

  private var arrC:ArrayCollection;

  Maybe it's getting used internally in several places, so you be sure if she be initialized already or not. Then use a code something like that...

  If (arrC! = null & arrC.length > 0)

  {

  ...

  ...

  }

  If you are using

  If (arrC.Length > 0)

  {

  ...

  ...

  }

  and it is not initialised it will give exceptional at the time to compile...

  For a logic if(a && b) be true both a and b must be true, so if same first one (a) is false it will not evaluate the second logic (b).

  Thus, the previous logic works.

• Removes really all the information from the old operating system recovery disc?

  Hello!
  I wanted to know if the recovery disk that came with my Toshiba computer deletes * all * the hard disk information, * or is it possible, which has damaged the malicious software that was installed on my computer sometime before resists after using the recovery disk? *

  "If I use my drive recovery the program just wonder if I wipe my hard drive and informs me that my data will be destroyed if I use this recovery CD. After this issue alone, it begins with the recovery process. Is ' normal for this drive, he'll ask me any other questions on "what partition will recover and so on and it starts recover after this issue alone?

  What Toshiba drive cleanup could I use the case, if this recovery disk deletes all old information from the hard drive to ensure that * all * of my last hard drive is wiped clean?

  Thanks for the reply!

  Hello

  If you use the disk recovery Toshiba, all data will be erased on the HARD drive.

  Before the start of the resettlement, the HARD drive will be formatted. Malicious software and other software will be deleted.

  So you n t need another drive or another program to erase the HARD drive.

  Try it and you will see that it works. But first, back up your data.
