• Password length must be greater than 6

  Dear people,
  I use Oracle 10 g when trying to create a form. I have a namesly of PASSWORD.when user text field to provide the password length must be greater than 6 a message alert will be lifted out.accordingly I wrote the following code in WHEN-VALIDATE-ITEM as follows.
  

  declare
       a number;
  begin
       if length(:block3.text_item5) <= 6 then
            a:=show_alert('ALERT19');
            clear_item;
       end if;
       end;

  Its working fine.but, my need is if the length of the password is less than 6, it should display the alert message and control should turn to the same element, and the element must be cleared.but since I wrote this in W-V-I control trigger moves to the next item.how to avoid it? What trigger should I use instead of this WHEN-VALIDATE-ITEM trigger? pls suggest me.
  
  
  Regarding
  Vids

  Hello
  You cannot use CLEAR_ITEM/FIELD in WHEN-VALIDATE-ITEM trigger because it is the restricted procedure see Help Forms.

  You can try you code like below.

  declare
        a number;
  begin
        if length(:block3.text_item5) <= 6 then
             a:=show_alert('ALERT19');
             :block3.text_item5:=NULL;
             RAISE FORM_TRIGGER_FAILURE;
        end if;
  end;

• How to make apdu.getBuffer () return buf which is greater than 133 bytes.

  {} public void process (APDU apdu)

  Byte [] buf = new byte [256];

  buf = apdu.getBuffer ();

  GOOD PRACTICE: BACK 9000 ON SELECT

  If (selectingApplet()) {}

  return;

  }

  apdu.setIncomingAndReceive ();

  switch (buf [ISO7816. {} OFFSET_INS])

  case (byte) 0 x 01:

  It is my method of process. I have a command APDU length 200 bytes I want the buffer to read and store in a local byte array. However, apdu.getBuffer () only entering the first 133 bytes of data.

  According to javadocs:

  "The APDU object is owned by the Java Card runtime environment. The APDU class maintains a byte array buffer which is used to transfer incoming APDU header and data bytes as well as outgoing data. The buffer length must be at least 133 bytes (5 bytes of header and 128 bytes of data). The Java Card runtime environment must reset the APDU buffer before each new message received from the CAD. »

  Given the length of the buffer is greater than 133 bytes, why he declined the remaining bytes?

  I use jCardSim on NetBeans IDE, version 2.2.2 of the java card.

  Also, could someone explain to me what exactly does apdu.setIncomingAndReceive ()? My code is able to build/run with and without it.

  Thank you

  Hello

  your code is not correct.

  never allow something outside the constructors and methods of customization that you know are called only once

  It will destroy your card as a 'new' allocates data to the eeprom.

  setIncomingAndReceive also toggle the protocol handler for receive mode (t = 1 and without contact, sends ACK in T = 0)

  then he makes the data available in the buffer

  the buffer is at LEAST 133 bytes, but it may be more

  If your command apdu contains more data, then these data are already in the buffer

  read the Lc offset to know the actual length.

  BTW, the comment of 'good practice' indicates that you use a code of example jcop as-is without understanding... I saw so many times!

  good luck, javacard is not as simple as java desktop... think "on-Board Unit 8-bit! You're not going malloc() in the main loop of arduino, right?

• How can I return at the beginning of the current selection?

  The hearing 3 and earlier versions, if I wanted to hear the audio selected, I made the selection in the Waveform Editor, you press Play and the selection would play.  He would play the same selection again if I stopped reading and press Play again.  CS5.5 and 6 that appears not to work the first time you press Play after selecting some audio.  After that, the audio is just resumes since when he arrested him.

  Is it possible to get the current time indicator to return at the beginning of a selection?

  I find that it is quite consistent in his behavior. But if you want to study the possibilities, go in Edition > Preferences > reading and you have several options of course altering it.

• Increments greater than 1 PHP loop

  Hi people,

  I'm trying to get a drop down menu to fill out in increments of 10 and I can't seem to get it. It must be easy, but research on the net does not seem to get me anywhere.

  Here's what I have so far:

  ----------------------------------------------------------------

  < select name = "distance_miles" class = "formrightcolumnnarrow" id = "distance_miles" >

  <? PHP

  for ($i = 0; $i < = 1000; $i ++)

  {? >}

  < option value = "<?" PHP echo$ i; > "> <?" PHP echo$ i; >

  <? PHP ;} ? >

  < / option >

  < / select >

  ----------------------------------------------------------------

  If I do what is obvious and change $i ++ $i + 10 the browser crashes.

  Can someone give me an idea how to make it work for a greater than 1 level?

  See you soon

  Dave

  $i ++ is a shortcut for $i = $i + 1

  Then...

  $i = $i + 10

• more than 4000 characters of parameter

  Layer of java calls a stored proc EXEC_DDL that makes an EXECUTE IMMEDIATE on the VARCHAR2 parameter string passed. Since the java layer goes to more than 4000 characters DDL statement, we get an error cannot bind for a long time... What kind of data can I use as a parameter instead of VARCHAR2 inside the stored EXEC_DDL Steven Feuerstein proc advises against the use for a long TIME in his book of PL/SQL. All types of BUSINESS are inside or outside the database objects, but I want just the java code to pass a DDL string greater than 4000 characters. I want to use the simplest approach.
  
  Thank you in anticipation

  What version of Oracle are you using? One thing - you can pass a variable of liaison which is more than 4,000 characters - so your options are rather spend a clob. Now if you're on 11g you can pass a clob in an immediate statement execute otherwise you will need to store the clob as varchar2 variable in the procedure, and then pass that variable in the statement execute immediate. In pl/sql, you can store up to 32K into a varchar2 variable.

• How the two function return values

  Dear all,

  Please explain, how the two values of function return?

  give a simple example.

  OK, a few examples...

  First example, using a type of structured on the database object:

  SQL > create or replace type tMyValues as an object (yr number, number, number of dy mn)
  2.

  Type of creation.

  SQL > create or replace function getMyValues return tMyValues is
  2 number of y: = extraction (year sysdate);
  number of 3 m: = extraction (sysdate months);
  number of 4 d: = extract (day of sysdate);
  5. start
  6 return new tMyValues(y,m,d);
  7 end;
  8.

  The function is created.

  SQL > set serverout on

  SQL > declare
  2 myValues tMyValues;
  3. start
  4 myValues: = getMyValues();
  5 dbms_output.put_line (' year: ' | myValues.yr);
  6 dbms_output.put_line (' month: ' | myValues.mn);
  7 dbms_output.put_line (' date: ' | myValues.dy);
  8 end;
  9.

  3 myValues tMyValues;
  4
  5 function getMyValues return tMyValues is
  6 retValues tMyValues;
  7. start
  8 retValues ('Year'): = extraction (year sysdate);
  9 retValues ('Month'): = extraction (sysdate months);
  10 retValues ('Day'): = extract (day of sysdate);
  11 return retValues;
  12 end;
  13. begin
  14 myValues: = getMyValues();
  15 dbms_output.put_line (' year: ' | myValues ('Year'));
  16 dbms_output.put_line (' month: ' | myValues ('Month'));
  17 dbms_output.put_line (' date: ' | myValues ('Day'));
  18 end;

  It is more likely to be used with an IF ELSE command, you do not want to define the condition for the calculation, roughly what the feature is designed for output.

• How to make FUNCTION returns several columns and several outputs line

  Hi all
  
  Kindly share your idea; Thanks in advance;
  
  I have the demo of the Table.
  
  DEMO table:
  
  name identity
  1 to 10
  1-a11
  1-a12
  2-b10
  2-b11
  3 ccc
  
  and the function is like:
  
  create or replace function (number of p1) return varchar2 as
  number of vid;
  VNAME varchar2 (20);
  Start
  SELECT id, name in vid, vname from demo where id = p1;
  return v1;
  end;
  /
  
  This function returns the output for the id = 3;
  
  BUT,
  
  I need output like (input 1)
  
  VNAME vid
  1 to 10
  1-a11
  1-a12

  A function returns a single data type.

  This type of data can be a type of atomic data (varchar2, number etc.) or it may be a type of data object to save, or even a type of collection data.

  Where will you use this feature? In PL/SQL or SQL?

  If you are wanting to use it in SQL, need you a pipeline for example function

  If you use it in PL/SQL and then just filling a data type of collection and return that will make. Although you should question why you want to pass large amounts of data around like that first.

  Explain your purpose and what you intend to do and we can recommend the best way.

• Function return undefined values

  My function returns undefined values. It seems that the return of the function statement is executed before the database is queried and values are assigned to variables. If I do an alert within the loop for () I get the correct values from the database, but these values are not affected before excecuting the return statement function. How can I do this differently?

  function getColumnNames(table){
      var rs1, rs2, rs3, rs4, rs5;
      db.transaction(function (tx) {
          tx.executeSql("SELECT * FROM schema WHERE table_name=?",[table], function(ax, results){
              var size = results.rows.length, i;
              var item;
              for (i = 0; i < size; i++){
                  item = results.rows.item(i);
                  rs1 = item.col1;
                  rs2 = item.col2;
                  rs3 = item.col3;
                  rs4 = item.col4;
                  rs5 = item.col5;
                                  alert(rs1); //correct value is returned here

  Hey Fabian,.

  You are quite correct that the return statement is executed before the database returns the results. There are ongoing asynchronous calls. You can set breakpoints in JavaScript code to see what is happening. You can correct the problem by using function callbacks. I edited your code below to use the callback functions - there might be a few typos, but the general approach should be wooded.

  function getColumnNames(table, callback){
      var rs1, rs2, rs3, rs4, rs5;
      db.transaction(function (tx) {
          tx.executeSql("SELECT * FROM schema WHERE table_name=?",[table], function(ax, results){
              var size = results.rows.length, i;
              var item;
              for (i = 0; i < size; i++){
                  item = results.rows.item(i);
                  rs1 = item.col1;
                  rs2 = item.col2;
                  rs3 = item.col3;
                  rs4 = item.col4;
                  rs5 = item.col5;
                      alert(rs5); //correct values are being returned
                  callback([rs1, rs2, rs3, rs4, rs5]);
              }
          });
      });
  }
  
  // example of how to call getColumnNames with callback
  getColumnNames('importantTable', function (result)
  {
      console.log(result);
  });
  
  // alternative version
  function onCallback(result)
  {
      console.log(result);
  }
  
  getColumnNames('importantTable', onCallback);
  

  I hope this helps.

• The function of enter the characters of left, right or middle of the member name?

  Does anyone know of a function or set of functions I can use to enter characters in a member name in a similar way to the functions of Excel RIGHT, LEFT, or MID? I would like to be able to write a rule to retrieve only certain characters in a member name.

  Hello

  If you look briefly into the ref of technology so you can find @SUBSTRING (String StartPosition [, EndPosition])

  StartPosition

  Beginning at the character position in a string to be included in the substring. An integer greater than or equal to 0, where 0 is the first character in the string, 1 corresponds to the second character and so forth.

  Final position

  As an option. An integer greater than or equal to 1, where 1 corresponds to the first character in the string, 2 corresponds to the second character and so forth. If the end position is not specified or is less than StartPosition, Essbase returns all other characters in the source string. Note that this is a different numbering scheme that uses the starting position.

  Now, I hope you have a good naming convention.

  Kind regards

• How to get the length of the string a vm?

  Hello

  I'm trying to automate some consolidation of virtual machines and would like to add script. I have over 800 virtual machines manually would not work.

  I would like to

  $allVApps = get-CIVApp

  foreach ($CIVm to ($allVApps |)) Get - CIVM)) {}

  find the number of channels and if greater than 8 consolidate them.

  }

  Someone has this practice? or something else?

  I'm in a cloud environment vSphere 5.5, installed latest powercli.

  Thank you

  Don't know why this does not work for others, but what I posted before work for me.  Here is a more complete version of how get the those of VAPP VM.  There are no doubt more direct ways, but that how I made it so far:

  1. get the VAPP

  $vApp = get-CIvApp-name 'Test-VAPP.

  2. get the VMS of vApp

  $VMs = $vApps.ExtensionData.Children.vm

  3. get the ones for the VM first in the list of $VMs:

  $VMs [0]. VCloudExtension.any.VirtualDisksMaxChainLength

  This last command returns 18 for me which is the "Length of the string" value in the properties of the Virtual Machine to the virtual machine in the vCD UI.

  I hope this helps.
