• Question of Apex_Util.Prepare_URL due to the Apex Util advise msg

  Hello
  
  I have the following code in a SQL statement in an IRR:
  
  APEX_UTIL. PREPARE_URL (p_url = > ' f? p =' | v ('APP_ID') |) ': 398 :'|| v ('APP_SESSION'): ':NO:398:P398_IDOBJ. VIMG_SEARCH. IDOBJ:', p_checksum_type = > 'SESSION') FullImg,.
  
  And it works as expected. However when I run the Util Apex advise I get the following:
  Region Source attribute (identifies the source of the region, region Type of reference Source)
  Check the V function used in SQL statements
  Performance category
  Message contains V/NV/DV function call in the SQL statement (can be a performance issue).
  
  Do I need to worry about this? or should I change the syntaxt in the APEX_UTIL. PREPARE_URL settings?
  
  Thank you
  Daniel

  In SQL (PL/SQL within the APEX blocks) the notation of the bind variable must be used:

  APEX_UTIL.PREPARE_URL( p_url => 'f?p=' || :APP_ID || ':398:'||:APP_SESSION||'::NO:398:P398_IDOBJ:||VIMG_SEARCH.IDOBJ:', p_checksum_type => 'SESSION') FullImg,
  

  V (...) notation is intended for program units PL/SQL database called from APEX.

• apex_util.prepare_url - by the way a comma between the item values

  Hello
  
  I created an application to illustrate a problem I'm having with the help of apex_util.prepare_url: http://apex.oracle.com/pls/otn/f?p=test_prep_url
  
  ' Tab ' without prep. url "displays a chart linking from this page (1) 2 using the usual f? syntax of p in the link, through two values, one for p2_schema_name and one for the p2_job_name values hidden on page 2. It works fine and the page 2 table displays data based on these past in values.
  The link is set up as: ' f? p =' || : APP_ID | ':2:' || : APP_SESSION. ": NO:2:P2_schema_name, P2_JOB_NAME:' |" schema_name | ',' || JOB_NAME
  
  ' Tab ' with prep. url "displays a chart which links from this page (3) on page 4 use apex_util.prepare_url to prepare the connection, passing two values, one for p4_schema_name and one for the p4_job_name in the values hidden on page 4. However, the decimal point is rendered in the browser '% 252C' url and p4_schema_name has the value "SCHEMA_A % 2CJOB_3" and p4_job_name is null (instead of = "JOB_3"). Of course, no data is found.
  The link is set up as: APEX_UTIL. PREPARE_URL ('f? p =' |: APP_ID |) ':4:' || : APP_SESSION. ": NO:4:P4_schema_name, P4_JOB_NAME:' |" schema_name | ',' || JOB_NAME)
  
  So I say to myself that I send you the value of point across properly, but I don't know what I would do differently. I hope the demo app described my problem enough so that someone can point out my blunder.
  
  The reason why I use APEX_UTIL. PREPARE_URL is that I would like to use session state protection and through the amount of control, but until I can get the sorted comma, I can't turn on session state protection.
  
  Thank you for your help.
  
  Alan

  Update: it is not prepare_url that does. Prepare_url encodes the comma in the list of item as % 2 c values. Then when the table XML gets converted to a blob for output, the % sign is encoded again. We will have to figure out what to do about this. In the meantime, only one element value can appear in the f? p link in a flash (fixed SVG chart) chart.

• How to get my size perfectly shot with the framework?

  I use first CS5! I had trouble getting my "dailies" to adapt to the screen. If you look at the screen on the left below, what should be the size and frame. But it seems not to slip in the window with the final cut. I don't know if he has extremely zoomed in or what the problem is. If I click on it, I can turn to the size of the window, but in this case, it changes the size of the video. I projected all the details of my video below. Please help with this ASAP

  

  When you launch first CS5, you are presented

  with a menu of pre-defined sequence types to choose from.

  You can skip this step by pressing "Cancel", then

  import (or capture) your media, and to do this:

  

  Or, right click on a media file and select "new sequence of the Clip".

  None of these methods will ensure your sequence matches your media.

• Question about the control panel user accounts in windows 7.

  This might be a bit of a strange question, but I'll see what I get. Basically when I enter the control panel via my username (not the admin account) and click on "Add or remove user accounts" and enter a password to admin, the photos on my user and admin account both fail (but they are there on the log on screen, etc.). But the guest account (which is disabled) the image of bag of comments showing. But if I enable the guest account, the image disappears. Strange. Any ideas how to get the pictures to show up there?

  Also, I will add that this occurs only in the standard user, not my account Admin accounts I converted my standard account to an administrator account, and the pictures then decided to appear.

  Thanks for your time.

• apex_util.prepare_url with the translated applications

  I have two questions about the use of apex_util.prepare_url with the translated applications:

  1. Why is-checksum in a different translated application of checksum in the original application?
  2. Is there a way to control the apex_url.prepare_url checksum function calculates?

  I have no application in both languages English (en) and Slovenian (sl). Link with English checksum would work if I put the Application primary language to English and the link with the Slovenian checksum would work if I set the main language Application to Slovenian. Application language is derived from the main language Application.

  Sometimes, the real problem for me is I have 'English' version of checksum when apex_url.prepare_url is called from the "Slovene" to application version.  As I mentioned before 'English checksum' does not work if the Application language is set to Slovenian.

  I have reproduced this behavior (with the exception of the problem described in the previous paragraph) on http://apex.oracle.com/pls/apex/f?p=15120. An application illustrates an another unanswered question/bug related to translated app: https://forums.oracle.com/message/11229437#11229437

  Is this Bug to Oracle APEX? Can anyone provide any advice or workaround?

  Hello

  bookmarkable (amounts of application or user level control) control totals depend on a salt value that is stored in the application. If the salt is null, there is a fallback to the alias of the application. If you update the salt by clicking "Expire bookmarks" on request > security attributes and re - publish the application, salt must be synchronized between the applications. Control totals should be the same, then.

• apex_util.prepare_url outside the ApEx

  Hello
  
  I'm trying to create a weekly task that sends an HTML email with links to the user session state protection application. However when I try to generate the URL with apex_util.prepare_url the checksum is not added to the chain. wwv_flow_api.set_security_group_id seems to have no effect.
  
  Any ideas?
  
  Kind regards

  Dan,

  Unfortunately, you have to jump through hoops to do it. I posted recently a method that defines a session programmatically context, that is, from outside the simple HTTP request for an application. What follows is an adaptation that allows prepare_url to do its thing. You can connect to SQL * more like your application schema and check it out:

  set serveroutput on
  
  DECLARE  l_cgivar_name owa.vc_arr;  l_cgivar_val owa.vc_arr;  --  l_workspace_id number;  l_application_id number := 132; /* change this to your application ID */  l_user varchar2(30) := 'USERUSER'; /* change this to the username to be associated with the session */BEGIN
  
       -- set up cgi environment  htp.init;  l_cgivar_name(1) := 'REQUEST_PROTOCOL';  l_cgivar_val(1) := 'HTTP';  owa.init_cgi_env(num_params => 1,param_name => l_cgivar_name,param_val  => l_cgivar_val);
  
    -- find workspace ID of application  for c1 in (select workspace_id from apex_applications where application_id = l_application_id) loop    l_workspace_id := c1.workspace_id;  end loop;
  
    -- set security group ID, session ID, app ID globals  wwv_flow_api.set_security_group_id(l_workspace_id);  apex_application.g_instance := wwv_flow_custom_auth.get_next_session_id;  apex_application.g_flow_id := l_application_id;
  
    -- create authenticated session for l_user  wwv_flow_custom_auth_std.post_login(    p_uname => l_user,    p_session_id => null,    p_flow_page => apex_application.g_flow_id||':'||1);
  
    dbms_output.put_line('workspace:'||v('WORKSPACE_ID')||', session:'||apex_application.g_instance||', user:'||apex_application.g_user);
  
    -- call wwv_flow.show so that the correct parsing schema and other globals are established for the application  wwv_flow.show (    p_flow_id => apex_application.g_flow_id,    p_instance => apex_application.g_instance,    p_request => 'FSP_SHOW_POPUPLOV'    );
  
    -- set array of protected page IDs for session state protection  wwv_flow.g_protected_page_ids(1) := '1';    -- this establishes page 1 as an SSP-protected page
  
    -- generate link with checksum using prepare_url  dbms_output.put_line(apex_util.prepare_url('f?p=' || v('APP_ID') || ':1::dummyrequest','utf-8','2')); -- the request references page 1, designated as a protected pageEND;/
  

  Note, the username parameter and the call to wwv_flow_custom_auth_std.post_login is necessary only if you want to generate a checksum of user (type '2') level. Links using this type of checksum may be used only by the same authenticated user which was set up during the generation of the checksum. For links that can be used by any authenticated user, a checksum of the application (type 1) level can be requested from prepare_url and for this, the user name parameter and the call to wwv_flow_custom_auth_std.post_login are useless.

  The second argument to prepare the url must match the implementation REQUEST_IANA_CHARSET of your DAD and the third argument is the type of checksum (3 = level of the session and is not appropriate here, 2 = user-level and requires you to make the configuration of the username first, 1 = application-level).

• Having trouble getting Windows media player to recognize and extract some burned CD when I insert the CD, nothing comes up on the tab extract. I have licenses for all the protected songs and the same CD was ripped in the past by using media player.

  My computer has a virus and before I wiped it's own, I copied all my files to blank CD I was able to extract these CDs on my computer but they are in the WMA format and I want them in MP3 format. I changed the rip settings but when I put in the CD Ripper re - it, nothing comes tab extract. I tried to delete all the files in windows media player and my computer but media player doesn't always recognize the CD tab extract. I have restored my music files from the bin to WMA, but I really need to extract the songs in MP3 format. What can I do to get Windows to recognize and tear my CD? Any help is appreciated.

  Thank you!

  Make sure that there is no CD in the CD drive. Then, go to Options - confidentiality of WMP and click the button Clear the Caches . Restart WMP, and insert a CD you want to re - rip. Are you able to rip the CD now?

  If it still does not work, you can try to rip the CD from another user account (if necessary, create a new user account in the control panel). Afterwards, you can move the files ripped to MP3 to your own original account. Tim Baets

• Trouble getting GPS coordinates in the Simulator

  Here is the code I use to get the coordinates of the GPS by train. It seems that every time that it expires and ends by 0 for the latitude and longitude of return even if I put together a location in my simulation-> GPS location... window and entered in the Options-> advanced-> GPS-> was cool my main application class, this function is called by a button.

  public void GetCurrentLocation() {         Criteria ct = new Criteria();            //ct.setAddressInfoRequired(false);          //ct.setAltitudeRequired(false);         ct.setCostAllowed(true);        ct.setHorizontalAccuracy(Criteria.NO_REQUIREMENT);        ct.setVerticalAccuracy(Criteria.NO_REQUIREMENT);        ct.setPreferredPowerConsumption(Criteria.POWER_USAGE_LOW);        //ct.setPreferredResponseTime(10000);        //ct.setSpeedAndCourseRequired(false);
  
          try {            myLP = LocationProvider.getInstance(ct);            myLP.setLocationListener(new myLocListener(this), -1, -1, -1);        } catch (Exception ex) {            return;        }    }
  
  public void GotLocation(Location myLoc) {        if(myLoc != null) {            QualifiedCoordinates qc = myLoc.getQualifiedCoordinates();            //Call webservice here.        }    }
  

  In the myLocListener.java

  package net.gasbot;
  
  import javax.microedition.location.*;
  
  public class myLocListener implements LocationListener{    GasBotScreen gb;
  
      public myLocListener(GasBotScreen gb)    {        this.gb = gb;    }
  
      public void locationUpdated(LocationProvider provider, Location location)    {        QualifiedCoordinates qc = location.getQualifiedCoordinates();  //I set a breakpoint here, but it rarely gets called, and when it does, the coordinates are both 0.        provider.setLocationListener(null, 0, 0, 0);        gb.GotLocation(location);    }    public void providerStateChanged(LocationProvider provider, int newState)    {
  
      }}
  

  Can you get it someone please let me know what I am doing wrong? I'll put the listener null once it gets a set location to update as I need it only once. I also tried to use the.getLocation(-1) and it does not work either. Is there something wrong with my Simulator? Or just something wrong with my code?

  I don't understand your code, in fact.  Why are reset you the listener inside the listener?

  In addition, you "eat" the exception where you get the provider. He is a likely area of failure, so I would put a trace and trace any exception.

  Another thing to try: try to set criteria to null when you get the provider: gives you the provider "by default".

• Try to reinstall Microsoft Flight program, but get a message saying that this installation produced the missing files

  Hello, I am trying to reinstall my game FSX but I get message indicating (impossible to recover the installation of product ID) when I try to install it on the phone using the automated installation system.  I think these are files that are not, but I read somewhere that they should be available in the files when I did the upgrade to win7

  I am a novice when it comes to these things, if someone could point me in the right direction it would be most appreciated.

  Thank you, Al

  Hello

  1. you try to activate Microsoft Flight Simulator?

  2. what was the previous operating system installed on your computer?

  3. don't you perform an upgrade installation or a custom installation of Windows 7?

  Please let us know when do you get this error message it's all install or activate Microsoft Flight Simulator to get help.

  If you have performed an upgrade installation of Windows 7, all you programs and data files would be transferred to the new operating system.

  If you install Windows 7 by performing a custom installation and do not format the partition during the installation, the files that were used in your previous version of Windows are stored in the Windows.old folder. The type of files in this folder depends on your computer.

• AutoGenerate field in Adobe Acrobat Pro and also form getting automatic flow on auto-add to produce the field to the form

  Hello

  I made PDF form that contains Radiobutton, TextBox, Button, CheckBox and barcodes in Adobe Acrobat Pro and everything works well.

  But according to the new requirement I need to "Autogenerate" some fields such as Radiobutton, text field and CheckBox by clicking on the button "add a field"and clicking on the button of the control should get auto generate this PDF form.

  Additional text that is already added to the PDF form get flow down when the fields if auto generate at the top of the form.

  Thanks in advance.

  You can add fields with a script (or show/hide existing fields), but you can not re-flow static PDF file text, unless it was created in LiveCycle Designer.
