• Put the results of a remote object in the datagrid

  I'm on day 3, but not using CF I use PHP server-side. I installed amfphp and everything works fine.
  
  I retrieve the data from the server and I can see it clear at all like a Bell in the debug value window
  'responds.serverInfo.initialData '.
  
  But I can't get the data to display
  'results' get ready.
  This is my code someone at - it ideas?
  Your Mike
  
  

  The error this is how I was setting results, should have been done like this:

  results = new ArrayCollection (responds.serverInfo.initialData);

• Setting cell values in the DataGrid control

  I have a request to a custom component called DataEntryDataGrid (which is a subclass of mx:DataGrid) I started on this blog: http://blogs.Adobe.com/aharui/2008/03/custom_arraycollections_adding.html

  The component works fine, but in this particular datagrid, I need special features.   After the first line of data is entered in the tabs of the user in the following line, I need the first and second columns to be filled based on the values of the previous row and then I need to automatically focus on the cell in the third column.  While the first and second columns must be always editable, they will be largely repetitive, and it would help if users did not have to enter the same numbers over and over again.  The first column of the new row should be the same value as the first column in the last row and the second column of the new row should be (value of the last row + 1). Example:

  DataGrid:
  
  | Slide No. | Specimen No. | Age | Weight | Length |
  |    1      |     1        |  5  |  65    |  40    |  <- This row is manually entered, just text inputs
  |    1*     |     2*       |  #  |        |        |
  
  * = values set programatically, these cells should still be focusable and editable
  # = this is where the focus should be
  

  The problem I have is that when I tab in the next line, the first value in the column don't prepare you.  The second column gets the value correct and properly displayed and emphasis is placed in the correct cell (the third column), but the first column remains empty.  I don't know why that is.  If I put a breakpoint in the code in the function focusNewRow() (which is called in the event of the dataGrid "itemFocusIn") (first column) "slideNo" value is set to the correct value, but after the 'focusNewRow' work finishes, a dataProvider trace [the current line] .slideNo shows the value is empty.  Non-null, just empty.  Traces of all other columns indicate the correct values.  Anyone have any ideas?  Here is the code for my main application:

  Sorry for the length of this post, but I hate to see people post without including enough information to solve the problem.  If there is nothing, I have left out, made me know.

  I think that in the NewEntryArrayCollection, I would wire up to generate a

  populated point instead of where you are right now.

• Name of the dynamic property of object in the table based on the value of a variable

  I have two paintings of custom class objects

  var obj1:Object1
  var obj2:Object2
  
  var array1:Array = [obj1[0], obj1[1], ...]
  var array2:Array = [obj2[0], obj2[1], ...]
  

  Object1 has a property named. Name while Object2 has a property named. Title.

  Now I have a common function including cab accepts an array (array1 or array2) and the name of property the object ("Name" or "Title") as input and needs to access this name of the property of the objects in the array:

  function myFunction(arr:Array, fieldName:String)
  {
      arr[0].fieldName  = "xxx";
  }
  

  the problem I have this achievement does not because the code in the function assumes that the property of that object in the table is actually a string "fieldName" while I want to dynamically determine the names of the fields based on the value of this variable, but cannot understand the syntax to do!

  Don't know if I'm clear - hope that makes sense... ;-) Thank you

  Hey p3pp3r,

  I think I understood you. Try the following and see if you get good results:

  function myFunction(arr:Array, fieldName:String)
  {
      arr[0][fieldName]  = "xxx";
  }
  

  Let me know how it turns out. Good luck!

• Insert the object into the table

  Hi all

  I would insert my type of object in a table without specifying the name of the variable.

  That's my bad example:

  create or replace type MY_TYPE_OBJ as object 
  (
    val1 number,
    val2 number,
    val3 number
  );
  /
  
  CREATE TABLE MY_TABLE of MY_TYPE_OBJ;
  /
  
  declare 
      myType   MY_TYPE_OBJ;
  begin
  
    myType := new MY_TYPE_OBJ(1, 2, 3);
  
    insert into MY_TABLE values (myType.val1, myType.val2, myType.val3);
    
  end;
  /
  
  

  As you can see, on my last procedure, I had to use the insert into statement with val1, val2, val3 name filed.

  Is there a quicker way to insert an object into a table? In the production environment of the object type that almost 100 filed is not so friendly to write each one by one.

  Thank you

• Model for PK not used on the tables of objects

  When uttering a primary key for a table of objects, the model for the primary key name is not used. SDDM (3.1.4 and earlier versions) is the addition of the string 'Oid_' before the name of the primary key table by default. So instead of "TABLE1_PK", the default name is "Oid_TABLE1_PK". It looks like the model is used by the object tables.

• Hidden Subtypeattributes in the table of object

  Hello
  
  Can someone clear this up for me?
  I had a supertype of tPerson, containing the attributes firstname, lastname, phonenr etc...
  
  I created a peopletable, based on the tPersonobjecttype.
  
  I created a subtype of tPerson, called tWebUserand added some attributes like emailaddress and password.
  
  Now, it is possible to insert instances of tPerson in the table, but it is (obviously) also possible to insert instances of the subtype tWebUser.
  
  Here's my question: where are the additional of the subtype attributes stored? If you do a describe table statement, you see just the columns store the attributes of supertype, if I do a select (normal) to the table, I see only the attributevalues, which belong to the supertype tPerson. But when I do a select using as tWebUser, I see all the attributes of the file tEpmloyee .
  
  Can anyone clear this up for me? I have created a few small business to become familiar with the Oracle objects and using tables to objects, but I have found no documentation about it.
  
  hereby the code to reproduce:

  -- Create the tPerson object
  create or replace type tPerson as object
  ( firstname    varchar2(50)
  , middle_name  varchar2(50)
  , lastname     varchar2(150)
  , phonenr      varchar2(15)
  , gender       varchar2(10)
  ) not final
  /
  
  -- Create the object table based on tPerson
  create table persons of tPerson;
  
  -- Create a subtype tWebUser
  create or replace type tWebUser under tPerson
  ( emailaddress   varchar2(150)
  , secretpassword varchar2(100)
  )
  /
  
  -- Insert a row the normal way
  insert into persons values(  'Peter', null, 'Boekelaar', '555 NETHERLANDS','M');
  
  -- Insert a row as an object
  insert into persons values(  tPerson('John', null, 'Doe', '555 ATHOME','M'));
  
  -- insert a row as an subtype
  insert into persons values( tWebUser('Jane', null, 'Doe', '555-ATWORK', 'F', '[email protected]', 'secretpassword' ) );
  
  select *

  Subtype attributes are stored as columns hidden in your table of people.

  If you choose to user_tab_cols rather than describe, you can see:

  select
  column_name, data_type, data_length, hidden_column, qualified_col_name
  from user_tab_cols
  where table_name = 'PERSONS'
  ; 
  

  [url http://download.oracle.com/docs/cd/E11882_01/appdev.112/e11822/adobjadv.htm#CHDCFBJI] Documentation tells you about the types of objects are stored.

• Create the object on the table of the default user space only

  Oracle - possibility to create a segment, perhaps with option different option of creations of segment. You can not insert in the segment until you have the opportunity on the tablespace. I hope that you understood.

• Hit testing objects in the table problem

  Hey guys, thank you very much in advance for any comments.  These forums are a great help.

  I have a serious problem with a loop in a table. I'm trying to hitTestObject each MC in a table against all other MC in this table.   That part works.

  The problem is that in my statement of hitTestObject, so obviously examines only 2 items at a time.  When touch 2 MC, I put a property called 'Touch' to true.  The problem is they are moving MCs and at one point touching only 2 / 3.  What is happening is:

  The loop runs once as the test Array [0] and table [1].  Say that those who are affected.  She sets their properties 'Touch' true (it's what I want).  THEN it works again test Array [1] and table [2] and finds that they are NOT overlapping.  It this process it defines two of their properties 'Touch' to false, EVEN IF one of them may overlap a different array object.

  I want to individual, set the property to "Touch" for each object in the table.  Currently, these properties are getting crushed even if 2 / 3 objects are superimposed in fact.

  That makes sense?  Essentially the "else" statement is too often called because certain combinations of array objects are not touch, but others are.

  -----------------------CODE BELOW-----------------------

  stage.addEventListener (Event.ENTER_FRAME, hitTestBalls);

  function hitTestBalls(e:Event) {}

  for (var m1:int = 0; m1 < MonsterArray.length; m1 ++) {}

  for (var m2:int = m1 + 1; m2 < MonsterArray.length; m2 ++) {}

  {if (MonsterArray [M1] .hitTestObject (MonsterArray [m2]))}

  MonsterArray [m2]. Touch = true;

  MonsterArray [m1]. Touch = true;

  trace (MonsterArray [m1]. The touching, MonsterArray [m2]. Touch);

  trace (M1, m2);

  break?

  } else {}

  trace (M1, m2);

  trace ("NotTouching");

  MonsterArray [m1]. Touch = false; MonsterArray [m2]. Touch = false;

  }

  }

  }

  While waiting for a response, here's something to consider.  You don't want to affect the Touching false at any time after that you start the analysis, only front...

  function hitTestBalls(e:Event) {}

  first put all wrong

  for (var m0:int = 0; m0< monsterarray.length;="">

  MonsterArray [m0]. Touch = false;

  }

  now test for overlapping - this way you don't overwrite anything with fake

  for (var m1:int = 0; m1< monsterarray.length;="">

  for (var m2:int = m1 + 1; m2)< monsterarray.length;="" m2++)="">

  {if (MonsterArray [M1] .hitTestObject (MonsterArray [m2]))}

  MonsterArray [m2]. Touch = true;

  MonsterArray [m1]. Touch = true;

  }

  }

  }

  }

  And if there be oinky be a pair that overlap as you say, you can add a breakdown; orders to end a loop when a hit is detected.

• Nested table of object type have only one record all the time

  Hi all
  
  I have a question regarding the storage of multiple records in a nested Table that is of type OBJECT.
  
  The program below that I wrote for the test and during the test, I was able to store only the last record in the nested Table.
  
  Please let me know what I did wrong here.
  
  Step 1:
  CREATE or REPLACE TYPE book_obj AS OBJECT (name varchar2 (25), author varchar2 (25), abstract varchar2 (4000));
  /
  
  Step 2:
  CREATE or REPLACE TYPE book_table IS TABLE OF THE book_obj;
  /
  
  Step 3: CREATE TABLE book (name, varchar2 (25), varchar2 (25) author, varchar2 (4000)) abstract;
  INSERT VALUES Accountants ('Harry Potter,' 'MK', 'It's magic');
  INSERT the book VALUES ("Ramayana', 'VK', 'It is mythiology'");
  COMMIT;
  
  Step 4:
  declare
  bookset book_table;
  ln_cnt pls_integer;
  Start
  bookset: = book_table (book_obj ('madhu', 'kongara', 'sudhan'));
  dbms_output.put_line (' the number is ' | bookset.) (Count); -> I see COUNT = 1
  bookset: = bookset_t(); -> Assignment to NULL.
  dbms_output.put_line (' the number is ' | bookset.) (Count); -> I see County 0
  for rec in (select * from book) loop-> now a loop twice.
  dbms_output.put_line (' name > ' |) Rec.Name);
  bookset: = bookset_t (book_t (rec.name, rec.author, rec.abstract));
  end loop;
  dbms_output.put_line (' the number is ' | bookset.) (Count); -> I can see COUNT = 1 (why?)
  END;
  
  I looped twice to fill two records in the TABLE IMBRIQUEE OF TYPE OBJECT. But when I see the Count I get only 1 and the data is also having the last record.
  
  Can you get it someone please let me know how to fill out the table nested with all records. Tell me where I am wrong.
  
  Very much appreciate your help here.
  
  Thank you and best regards,
  NKM

  Because instead of add to bookset collectionto set (ergo replacement) it a collection containing recovered book. Use:

  declare
      bookset book_table;
      ln_cnt pls_integer;
  begin
      bookset := book_table(book_obj('madhu','kongara','sudhan'));
      dbms_output.put_line('The count is '||bookset.count); --> I can see COUNT =1
      bookset := book_table(); --> Assigning back to NULL.
      dbms_output.put_line('The count is '||bookset.count); --> I can see count as 0
      for rec in (select * from book) loop --> Now Looping two times.
        dbms_output.put_line(' name > '||rec.name);
        bookset.extend;
        bookset(bookset.count) := book_obj(rec.name, rec.author, rec.abstract);
      end loop;
      dbms_output.put_line('The count is '||bookset.count); --> I can see COUNT =1 (why)
  end;
  /
  The count is 1
  The count is 0
  name > Harry Potter
  name > Ramayana
  The count is 2

  Or better use bulk collect:

  declare
      bookset book_table;
      ln_cnt pls_integer;
  begin
      bookset := book_table(book_obj('madhu','kongara','sudhan'));
      dbms_output.put_line('The count is '||bookset.count); --> I can see COUNT =1
      bookset := book_table(); --> Assigning back to NULL.
      dbms_output.put_line('The count is '||bookset.count); --> I can see count as 0
      select  book_obj(name,author,abstract)
        bulk collect
        into  bookset
        from  book;
      for i in 1..bookset.count loop --> Now Looping two times.
        dbms_output.put_line(' name > '||bookset(i).name);
      end loop;
      dbms_output.put_line('The count is '||bookset.count); --> I can see COUNT =1 (why)
  end;
  /
  The count is 1
  The count is 0
  name > Harry Potter
  name > Ramayana
  The count is 2

• Not possible to store several fileReference object to the same table?

  Hi all

  I'm trying to store several fileReference object in a table. But whenever I have a new object each time push() artefacts which is already in the table gets set on the object later.

  I let the user selecting an image. Then I push the fileReference object selected in a table like my_array.push (FileReference (event.target));

  If I then executes a loop on 'my_array' to check he's glad I get the most recent pushed fileReference for each index object in the table.

  With an object pushed:

  1 Image1.jpg

  With two objects pushed:

  1 Image2.jpg

  2 Image2.jpg

  Anyone has any ideas on this?

  Thank you very much

  Hello

  Sorry for the delay.  You've probably discovered the answer to that now, but in case you do not have or someone else runs into this issue here is the code that should fix this:

  // Local Files
  private var fileList:Array = new Array();
  private var localFiles:FileReference = null; 
  
  private function browse(event:MouseEvent):void {
       localFiles = new FileReference();
       trace("[Browse] Using local files");
       localFiles.addEventListener(Event.SELECT, onLocalFilesSelected);
       localFiles.browse();
  }
  

  The problem is you have had one instance of localFiles, and while that you stored more than once in the table, when the reference has changed it performs all of the table.  Instead, I'm newing up a FileReference browse() service, so that we get a new each time.  I hope that makes sense.
