• Why using the typewriter in acrobat 9 adds less file size that the use of the text of the comment in acrobat 11 tool?

  Why using the typewriter in acrobat 9 adds less file size that the use of the text of the comment in acrobat 11 tool?

  Two employees, one using acrobat 9 and the other uses acrobat 11. The two employees open a secure document one page 105 KB in size. Used using acrobat 9 using the typewriter tool to add comments. Document increases in volume to 137 kb. Second employee using acrobat 11 uses the comment add the text tool (since it is no longer a typewriter tool). This employee has to use tool once and the document immediately increases size of 105 k to 950 + kb. Why is this? What can be done to avoid this?

  As I suspected much earlier, the difference is in the fonts that are used for the text. For the smaller file, text annotation font is Times Roman. that is a policy that is essentially built into Acrobat/Reader. For the larger file, the font is Tahoma, which is not an integrated police force, which ends by happens so the entire police gets embedded in the PDF file. The size of this font on disk file is 681KO on my system (Mac), and it ends up taking more space when they are embedded in the PDF file. The same type of thing happens with form fields and this is done so that all characters in the font are available when the text is changed in a system that may not have the installed font.

  One of the problems is if you try to reduce the size of the file by changing the font that used up one of the built-in ones (Courier, Helvetica, TImes Roman), Acrobat does not remove the now unused of the file font information, if you do not get the reduction in file size that you can imagine, even if the font is no longer presented as being incorporated. I submitted this as a bug some time ago, but it has not been fixed.

• How can insert quary in database by using the collection.

  Hi friends,
  
  
  My friend advice me to insert several point with collection for the use of multiple lines. But I don't know how to use the collection. How do I create the form to insert data using the collection.
  Please send me any link or example .au insert data into database by using the collection.
  
  
  
  My problem is:-
  
  I have a bill with several point for example. Grapes (25) with amount here and now I want to add these question with quantity in my database, Badam (145), banana (49), Apple (12)

  Hello

  I would do something like the code:

  BEGIN
   DECLARE
    vDATE DATE;
   BEGIN
    vDATE := TO_DATE(:P1_DATE1,'DD.MM.YYYY');
    WHILE vDATE <= TO_DATE(:P1_DATE2,'DD.MM.YYYY')
    LOOP
      INSERT INTO ABC (DTE, LEAVE)
      VALUES (vDATE, :P1_C);
      vDATE := vDATE + 1;
    END LOOP;
   END;
  END;
  

  You must ensure that the datepicker points both use the ' JJ. MM YYYY ' date format.

  Hi Frank,.

  In the example, the '{cache-name}' is supposed to be replaced by a table name or view of data that is queried for the cached data. Its purpose is show how to pass parameters to the constructor of class.

• Interactive report editable without using the Collection

  Hi Experts,

  I use Oracle Apex 4.2.5

  Is it possible to create an interactive report that can be changed in the same page? If the user edit a field, it must get updated in this table.

  Let me know if this is possible without assistance from the Collections of the Apex

  BR,

  Patrick

  Paul Broughton says:

  Hi Patrick,

  I also agree there is no out of the box solution, I need this for an application and I used elements of the APEX of the APEX_ITEM API

  Here is a very basic example that I have not tested, but you have a question, something like:

  [code]

  Select

  APEX_ITEM. DISPLAY_AND_SAVE (1, empno) as patient_id,

  APEX_ITEM. TEXT (2, ename) as ename

  Of

  EMP;

  [/ code]

  Make sure you use columns of standard report as your column types.

  When you click on submit you'd have a process similar to the following:

  [code]

  Start

  BECAUSE me in 1... APEX_APPLICATION. G_F01. COUNTING LOOP

  Update emp

  set ename = apex_application.g_f02 (i)

  where empno = apex_application.g_f01 (i);

  end loop;

  end;

  [/ code]

  That's assuming you don't need inline editing.  If you do this will require an even more customized solution, but the way above requires no collections.

  Thank you

  Paul

  Hi Paul,.

  I think that IR out-of-box features do not work correctly when you use the APEX_ITEM functions in the query.

  Here's another one you could use APEX 4.2

  Yet another way to create & quot; editable interactive report & quot;

  Kind regards

  Hello

  I changed and then brought back to the State that you had.

  The problem here is that you have status and Seq_id returned with APEX_ITEM. HIDDEN, but you have not selected the Show check box for those columns attribute report tab.

  Thus there is no f06 and f09 only named elements in your HTML DOM and therefore no APEX_APPLICATION. G_F06 and G_F09. If your processes

  FOR correct here is what you do

  1. mark the status and Seq_id as indicated in the report attribute tab columns
  2. change the ACE status display hidden to report column Standard. Change display of the Seq_id also report Standard column

  Note that when a column is not marked to show in the report he becomes any and you don't see the associated items in the DOM HTML.

  See you soon,.

• using the collection as an array

  Hello
  I want to use a collection as a Table.Can someone give me a code for this example.
  
  I'm a collection to the parameter and want to join another collection that lines with another table. I want that, because if I'm going to do the operation loop taking elements one by one and in comparison with the record in the DB table, the performance should be degraded.
  
  Please give the solution for the use of a collection in a table to join with another table.

• Data Modeler: how to create and use the collection type

  Hello
  essentially of departure I don't understand how (for example) create and use the data based on the type of data varray type.
  
  Please notify.
  Thank you
  Andrew

  Hi André,.

  You can create new types of collection (varray/table) in two ways:
  (1) in the browser - find 'Types of data' > 'Types of Collection' node menu dropdown - there just 'create new collection type' it
  (2) in the types of data model diagram - you can create collection "some type structured" or collection of references to the it - use 'new Collection... '. "tool and click first on sight structured type and after the structured type that will contain the collection - new attribute is added to the latter and if there is none this type of collection already didn't set the new collection type are created and you can change it later.

• Why using the driver NOR-DAQmx ANSI C functions in a thread causes a deadlock?

  Firstly, apologies if this is bad advice, but it seemed the closest fit.

  I use MSVC 2008 Express with the library in ANSI C NI DAQmx for some analog output with a box USB-6009. I create a thread to handle the signal generation is based on fixed time. My main thread running the user interface. I found that I get intermittent blockages in release, so that libraries mode NOR are responsible (in the second thread) and I use MSVCRT features (on the main thread). My test code is attached as "deadlock2.cpp".

  I used WinDbg to try to find the cause of the deadlock. Traces of the battery of my two sons are attached as t1_stack.txt and t2_stack.txt.

  It seems that the MSVCRT localtime() function uses a lock when it is called for the first time and then went to lock the Windows DLL loader lock. At the same time libraries NOR (or less libraries mxs) are responsible for locking the charger DLL is being held. The mxsutils library uses getcwd() which seems to try to block something the MSVCRT and therefore my two sons are now deadlocked.

  I can probably work around this by calling the localtime() and the NOR-DAQmx functions before I spawn my second thread so that the DLLs are already loaded in the process. However, I have no guarantee of this to continue working if something changes in the future, and if there are any locks going on finally having the DllMain() calls for a thread hanging may still cause a deadlock. If my results are correct, is it likely that NEITHER would fix the dll for not trying to make something complex in their DllMain()?

  According to NI Measurement and Automation Explorer, I'm under DAQmx libraries v9.3.5f2. I download the latest version now to try, but it will take time.

  Hi dmcminn,

  Thank you for the comprehensive and detailed bug report. I was able to reproduce the problem with NOR-DAQmx 9.6 using the code you posted. I reported it to the R & D team suitable as CAR #366538.

  I agree with your analysis of the problem. Getcwd() so the first call to __tzset() acquired _ENV_LOCK, which Microsoft has documented as the "lock for environment variables. __tzset() also called GetTimeZoneInformation(), which can load additional libraries, that you have demonstrated.

  Here are a couple more possible solutions, but they are not great:

  • Link to the static version of the CRT (/ MT instead of /MD). This would bind a separate copy of the lock of the CRT table in your program, and DAQmx would continue to use the lock to MSVCR90.dll table. They use more of the same _ENV_LOCK.
  • Build using a different version of Microsoft Visual C++ (for example 2005 or 2010). MSVCR80.dll MSVCR90.dll and MSVCR100.dll own separate copies of the lock of the CRT table.

  Whatever it is, it does not eliminate the fact that mxsutils called the CRT while now the loader lock, and this function CRT acquires another lock.

  Furthermore, the forum Multifunction DAQ is a better place to ask questions DAQmx.

• Why used the work of my Movie Clip 3D rotation tool?

  Im trying to use the tool rotation 3d for the first time. I have a picture, set as a (movieclip) symbol on its own layer. However, when I select the 3D rotation tool, it me does not change the clip. It shows me just the empty arrow.
  Could someone please shed some light on this? The only information I can find about this tool doesn't work does not correctly is if you try to manipulate an object that is NOT a clip.

  Thank you!

  Hi Sarah,.

  The screenshot shows that you have selected the 3D translation tool. Just press W to activate the 3D rotation tool (or click and hold on the Group of 3D for the suboptions tools and select the rotation tool). You should be able to use the 3D on this clip rotation after that. Let us know if there are any other questions.
