• Inline when checking for null values

  Hi, I'm currently stuck with a problem regarding the verification of null values. The problem revolves around an address line, where I want to display values such as roadname, number, zip code etc. The address line is supposed to be on a single line, no carriage return. The address line must be prepared for null values, if we say it have no house number. That's why I am attaching these tags with an if statement:
  
  & lt;if@inline:HOUSENUMBER!= "? & gt; & lt;? HOUSE number? & gt; & lt;? end if? & gt;
  
  But when I try this in my report, it seems that @inline BEEP do not take into account the signal no one checking the logical expression and always showing the content enclosed in the case. When I remove @inline, it works as it should, but there is a carriage return when the value is zero.
  
  Does anybody know a solution for this?
  
  Thanks in advance

  Hi Kim

  Hmmmm works for me. I noticed that you have a lack? just before the if. You can also try @inlines, it's a subtle difference in functionality.

  Even without the FI doesn't text collapse left anyway?

• quick 1-test for null?

  Hey. Tried isNull (x), objEqual (x, null) and if (x == null) does not.

  What is the proper way to check for null in Java BB? X can be a class or a Timer (or something)...

  Happy new year 2010 new!

  Justin

  If (x == null) {}

  works for me, for all objects.

  You can also do

  If {(x instanceof )

  This test fails if x is zero.

• checking int null value

  Hello
  a little silly question how to check the value for null int...
  I'm dealing with java.lang.IllegalArgumentException When you call the function defined in AM when inputText which provides function the int parameter contains no value.
  How can this be avoided?
  for the types of objects, you can use operator 'is' Java, what primitives?

  You can use the following piece of code for int a

  If (("".equals (a)) |) ("null".equals (a)))
  {
  int one is null
  do something
  }

• How to check for the application ID in a function of connection?

  Hello
  
  I have a connection procedure which is something like this:
  

  wwv_flow_custom_auth_std.login(
      P_UNAME       => :P58_USERNAME,
      P_PASSWORD    => :P58_PASSWORD,
      P_SESSION_ID  => v('APP_SESSION'),
      P_FLOW_PAGE   => :APP_ID||':15'
      );

  And the authentication procedure is this:
  

  create or replace
  FUNCTION  "ACL_CUSTOM_AUTH" (
      p_username IN VARCHAR2,
      p_password IN VARCHAR2
      )
  RETURN BOOLEAN IS
  BEGIN
    FOR c1 IN (SELECT 1 
                FROM acl_employees
               WHERE upper(userid) = upper(p_username)
                 AND mot_de_passe = p_password)
    LOOP
      RETURN TRUE;
    END LOOP;
    RETURN FALSE;
  END;

  I want to check for an application in the acl_employees table ID, because I want to check if this user is credited for THIS specific APP_ID, adding a following kind of code to the function of authentication:

  AND application_id = :app_id)

  The problem is that the connection API takes in charge only two parameters for custom authentication: user name and password. How can I switch the APP_ID to authentication?
  
  Thank you for your help.

  It is sometimes easier to check the user before calling the connection custom Apex then past just a password to NULL to the connection works if the check fails. Something like that before the connection:

  DECLARE
  v_dummy NUMBER;
  BEGIN
  SELECT 1
  INTO v_dummy
  FROM acl_employees
  WHERE upper(userid) = upper(p_username)
  AND application_id = :app_id;
  EXCEPTION WHEN NO_DATA_FOUND THEN :P58_PASSWORD := NULL;
  END;
  

• checkbox when checked is null

  Hi all
  
  I'm having trouble with a box of the item not db on a multiline block. Basically, I want to be checked for each line, as the default functions and differenct to call froma loop on the block based on what is the value of the box each checbox. I set the value when enabled = 'Y' and value when disabled = n and the initial value = 'Y '. But when I run the form isn't the treatment that is supposed to happen when the box is checked. I put in the pl/sql debugging messages and that they show the value of the checkbox to be null when it should be 'Y '.
  
  Has anyone encountered this before?
  
  Thank you

  Are the records for the block questioned from the database? If so, the initial value will be used, it is only used for new records. To set a data-case non-base value to check to a record of queired, you must set in the POST-QUERY-trigger.

• Thunderbird by failing to check for mail. Must be done manually. RESOLVED by 38.3.0

  About two weeks ago or so, Thunderbird stopped checking for mail. I always got it for 3 minutes and it's always worked so far. So now, I have to manually hit "Get Messages" to receive my mail. Find out how to fix this?

  Thank you!

  Please update to version 38.3.0 which came out today.
  Is this better?

• Thunderbird 38.2.0 does not check for incoming mail, freezing

  I used Thunderbird for years without problem. Update 38.2.0 was so bad for me that I had to uninstall it. Questions:

  (1) would not check for incoming mail
  (2) popped up the windows of information that had no text and even not closing "x" in the corner (although I could click the right superior whiteness and she closed)
  (3) screen would freeze. At least the closing 'x' still - working but it's the only thing that makes.

  Every update I've ever had until this has been perfectly integrated. This one was painful.

  My question is when there's an update to correct these problems?

  Please update to version 38.3.0 which came out today. Will probably solve your problem.

• Check for new messages at startup does not work in the first period of 10 minutes after v38 updated. Work at the end of 10 minutes. CAUSE unknown - went away after reinstall

  After the 38.0.1 of 31 thunderbird update does not check for messages at startup, tried on two workstations, mail for a single account on each account, one was pop and other imap. The check box in the accounts-> server settings has no effect. Or not safe mode or the option advanced messages "include this server when getting new messages". "." Activity Manager shows not even he is trying to connect. The question mark function still works well so if I wait 10 minutes he gets messages automatically...

  I reinstalled the program once more and it works OK but it's already happened and it fails once more.

  The last installation permanently solve this (so far)?

• Cannot automatically download new messages and auto answer with out-of-Office message must manually check for new messages, so he can do

  I use Mozilla Thunderbird 31.3.0. I know how to create a message filter, to implement a response message automatic, but impossible to get Mozilla to automatically download new message and auto reply with the message in the filter, unless I have manually check for new messages, this is the only way to make it work. I looked online and can't seem to find an answer to that particular question. According to everything I found, I have the right boxes checked in the server settings: automatically check for new messages at startup, check new messages, check for new messages every x amount of minutes. It's one thing to have leave my computer and open Thunderbird for this works, but having to manually check for new messages get the AutoReply to work defeats the whole purpose of having an automatic response, because I use them for vacations, holidays, etc. I wondered if there are security settings that cause this problem, but if so, I don't know what changes to do to them. Thanks in advance for any help. It drives me crazy.

  I find it a little odd that Thunderbird does not mail on the calendar, you may have an add-on or antivirus program that prevents this.

  Now shift while you start Thunderbird will begin with disabled modules to check if the messages are automatically.

  By air is to the right, use the autoresponder Verizons. This link might help with this http://www.verizon.com/support/residential/internet/highspeed/account+tools/email+tools/questionsone/85621.htm#
  You say that not having is not such a context in Thunderbird is something that needs fixing. This idea comes across because Outlook has such an option. what most people don't know of it only works with Exchange server. There is no "vacation response" in the specifications of the mail server so every server implements differently.

  As all cars have a radiator, you can't take any radiator, and simply put, they are subtly different even if they perform the same purpose. Goes same for stakeholders of vacation, they perform the same function, but they differ between brands of e-mail server software.

  Thunderbird leaves the server end to expose the feature, because they are really the only ones who understand what they were doing. Outlook exposes the option and especially greys out.

• TB download every mail, whenever it checks for new mail, even if it has been downloaded before.

  I now have about 14 copies of each mail, seems like it does not recognize that it has already downloaded.

  Hi, well, POP3 is not designed to keep the emails in the Inbox on the server permanently. Because when checking for new messages, to my knowledge he needs to go through all the mails in the Inbox on the server to check if it is already downloaded or not.

  To this end, there is a cache on the client side. The size of this cache can be configured in the following manner through prefs.js:

  user_pref ("mail.server.server1.numHdrsToKeep", 10000);

  I don't know the default value, but you can set it for example 10000 (cache to 10000 mails). You must check in your server folder to which it is (server1, Server2, etc) according to the other entries in the config file.

  However, you should not keep mails to "Infinity", I do not know the maximum value possible for this and I guess that we slow down the download of new messages with the increase in number of mails.

  I have to admit, I also use the above setting to increase the memory cache my caches POP3 to have emails available on my PC, as well as on my smartphone email client. However, what I did to not blow: in my mail provider (GMX) web-based configuration, I specify that emails are automatically deleted from my Inbox on the server after 3 months. This constantly maintains the number of mails away from 10000...

• How can you cancel the download of an update that was started by after having pressed the button "Check for Updates" in the window "On Firefox", please?

  How can you cancel the download of an update that was started by after having pressed the button "Check for Updates" in the window "On Firefox", please? If possible, please cover all platforms, Mac, Windows, Linux, although the first mentioned is what currently applies to my situation.

  Thank you.

  Such a download is usually recorded in a updates or updates folder in the program folder or the Firefox application.
  You can delete this folder to cancel the download.

  If the files have already been downloaded, then delete the files in the folder updates\0 and updates.

  El Capitan checks for virus/malware infections in the system?

  There is so much discussion on the iMac does not require does no antivirus, because it is well protected. On the other hand, horses Trojan seems to get their way in a system through vulnerabilities in browsers or other applications. Is there a way to know the State of health without having to pay for a subscription and the loading of the system with the external scanners and controllers as the extra load of the system?

  Yes, Mac OS X has built-in protection that is updated regularly (in the background). You don't need any other software.

  Adware and malicious software is different. If Safari is supported with pop-ups,

  Quit the Apple Safari > force quit menu. Relaunch Safari since the Dock icon while holding the SHIFT key.
