• Get the bind variables name string SQL or the cursor

  Hello
  
  Is there way to get of the bind variables name string SQL or the cursor?
  
  Example of

  DECLARE
    l_sql VARCHAR2(2000);
    desctab DBMS_SQL.DESC_TAB;
    curid   PLS_INTEGER;
  BEGIN
  
    l_sql := 'SELECT * FROM emp WHERE mgr = :X and deptno = :Y';
  
    curid := dbms_sql.open_cursor;
    dbms_sql.parse(curid, l_sql, dbms_sql.NATIVE);
    ....
  END;

  What I mean with the SQL string:
  I love to get using some functions from above code variable l_sql all the bind variable.
  In this case the function should return array where is for example: X and: Y
  
  Back to bind the cursor variable names, I mean same but rather string I pass number of cursor.
  
  Y at - it sucks ready function or some may share a code customized for this purpose?
  
  Thanks

  I found there are wwv_flow_utilities.get_binds of the function not documented in APEX packages that do what I want.
  Usage example

  set serveroutput on
  DECLARE
    binds DBMS_SQL.varchar2_table;
  BEGIN
    binds := wwv_flow_utilities.get_binds('select :P1_TEST from dual');
    FOR i IN 1 .. binds.count
    LOOP
      dbms_output.put_line(binds(i));
    END LOOP;
  END;
  /
  
  anonymous block completed
  :P1_TEST

  But I would not use these functions without papers as those who can change or there is no future versions APEX.
  Is there a documented function or the custom function that do the same thing as wwv_flow_utilities.get_binds?

  Some old basic example code of my friends. Also the media getting the bind variable of PL/SQL code blocks anon.

• Using the string Variable name to ChnFind

  Overview - I find crossing points of zero on a set of data so that I can calculate the phase shift of channel to another in my data.

  Small image - I start by finding the zero 1 cross in the data, once I found I want to use the index to find the next and so on

  Problem

  The posted script comes from looking for the 1st pass by zero before moving on to the next channel. The problem is that I can't find out do my group and channel changes with loops.

  Option Explicit  ' force explicit declaration of all variables in a script.
  
  Dim intCount, intChan ' loop variables
  
  Dim z
  
  IntCount = 2 GroupCount-1 ' groups
  
  Call GROUPDEFAULTSET (intCount) ' change the current group
  
    IntChan = 1 to ChnNoMax ' Browse channels
  
       Z = ChnFind ("Ch(""[intCount]/[intchan]"")<0") 'this="" does="" not="" work,="" but="" i'm="" not="" sure="" how="" to="" fix="">
  
      MsgBox (z)
  
    next
  
  

  I don't know I'm missing something obvious.

  Hi Michael,

  You need not global variables to simplify this, but I would certainly use object variables to simplify.  When indexing of groups or channels, it is easier to use the variable of index with the Data.Root.ChannelGroups collect or Group.Channels collection directly.  I also prefer to store the group object and the channel object in a variable.  For example, you can then use Channel.DataType to add exactly the same string data to the new group coming from the old group.  You can also easily get the name, unit and all sorts of other properties directly from the object variable.  I prefer to use a separate group object variable to reduce congestion in the colde, although it adds 2 lines to your example of code snippet.

  Set FromGroup = Data.Root.ChannelGroups (intCount)
  
  Set FromChannel = FromGroup.Channels (intChan)
  
  Define participatory = Data.Root.ChannelGroups ("Index" & FromGroup.Name)
  
  The rise in the value  = ToGroup.Channels.Add (FromChannel.Name & "Rising",  DataTypeChnFloat64)
  
  Fall in the value = ToGroup.Channels.Add (FromChannel.Name & "Falling", DataTypeChnFloat64)

• How to get the string (specified by row and column) of txt file with labview

  Hello world

  How to get the string (specified by row and column) of txt file with labview

  THX

  As far as I know, a text file has no column.  Be more specific.  Do you mean something like the 5th word on line 4, where the words are separated by a space, and lines are separated by a newline character?  You can read from the spreadsheet String function and set the delimiter to a space.  This will produce a 2D channels table.  Then use the table to index and give the line number and column number.

  Thanks in advance

  Hello

  I believe in jython would make it almost similar

  for example

• How to get the client computer name database?

  Hiya
  
  As part of the authentication of the user of our application, the requirement is that if a user is connected from a machine, the same connection of can not the user to different machines at the same time.
  
  In Forms6i, we had accomplished this by using the following query:
  
  Select the Terminal
  Session $ v
  Where username = v_username
  And v_terminal terminal <>;
  
  Where
  v_username = USER-> Oracle Forms reserve Word
  v_terminal = Client_Win_API_Environment.Get_Windows_Username
  
  In Forms 6i, the column Terminal of V$ Session used to return the name of the local client computer.
  
  However, in the form of 10g, it returns the name of the computer on which Oracle Application Server is installed, which seems correct to me.
  
  So my question is how do we get the client computer name of the database in the context of Oracle's 10g? Is there another package of database or view/table that returns the client computer name?
  
  Your suggestions/comments will be much appreciated.
  
  See you soon
  
  Mayur

  We have implemented the same exact requirement to retrieve the IP address of the client (WebUtil provides a function for this) and write it in the field v$ session.action (this can be done using the dbms_application_info package DB). We are so in shape 10g v assessment $session.action instead of v$ session.terminal.

• How to get the global variable for an instanceId

  Hello
  
  I have data in global variables of an instance level. And using that instanceId, how can I get the global-level variables data.
  
  Please me tips
  
  
  Thank you
  Sailendra

  Hello
  I guess you want to get the value of the external variable within the process. You can do like this:

  assuming that it is of type string. For other types of type cast properly...
  String extVarValue = (String) (New Component(instance: this)).get(attribute: extVarName);

  Replace "extVarName" with your project name. It returns the value of your project for the instance that you are currently working.

• Get the string invalid Base64 of image of toDataURL() for the first time in 10 of blackberry webworks

  Hello

  I need to get the Contact image converted to string Base64 using BB 10 Webworks (blackberry.pim.contacts) I get only the contact.photos [0] .smallFilePath which returns the path to the phonebook file.

  Now, I want to get the image of this path and convert it to a Base64 string.

  Here's the javascript code :

  var img = document.createElement ('Image');
  var canvas = document.createElement ('Canvas');

  function getBase64Image (p) {}
  img.setAttribute ("src", p);

  Img.width = Canvas.Width;

  Canvas.height = img.height;

  CTX var = canvas.getContext ("2d");
  ctx.drawImage (img, 0, 0);
  Return canvas.toDataURL("image/jpg");

  }

  This means bad Base64 string of image for the first time. When I convert this string to the image it displays white screen. But returns a string in the Mithraeum and after conversion, display a correct image.

  I use Blackberry Z10 (OS 10) for the test.

  I think that the canvas is not drawing image properly for the first time.

  I have searched and tried many things, but not got success. What will be the solution.

  Thanks in advance.

  My guess is that the image did not load the source completely still. Setting the src / image loading is an asynchronous event, which means that your code will continue to the next line regardless of whether the image has loaded yet or not.

  After calling setAttribute instead of execute the code of the Web, you will probably need define an event on img for the load event listener. Once the image is loaded, you can then use the img with canvas variable to retrieve its data.

  Note that getBase64 will return immediately, so you may need to develop some sort of mechanism to wait before returning, or the asynchronous approach and integrate reminders for the success trigger the next piece of code.

• How to get the string contents of itemByRange?

  Hi all

  Here's what I'm trying to achieve:

  I selected a Word and you want to get the content of the 1^st word in the string (the name of a person).

  

  In fact, the selected text is the source * a hyperlink and my goal is to get the name of the person designated by him.

  [0] is the same as hyperlink.source.sourceText

  Since I can not get the paragraph or line where the selected word is (or simply do not know how to do this), I'm trying to get the full story: from the 1^st character of the selected word and moving backward character by comparing its content. When it hits '\r', I know it's the beginning of the line. This way I can get the part of the line, I'm interested with the itemByRange() method, which returns "Array of Character."

  Main();
  
  function Main() {
      var doc = app.activeDocument;
      var sel = app.selection[0];
  
      GetName(sel);
  }
  
  function GetName(txt) {
      var lastCharacter = txt.characters[0];
      var character = txt.characters[0];
      var story = txt.parentStory;
      var index = lastCharacter.index;
  
      while (character.contents != "\r") {
          character = story.characters[index];
          index--;
      }
  
      // Array of Character itemByRange (from: varies, to: varies)
      // Returns the Characters within the specified range. 
      var arr = story.characters.itemByRange(character, lastCharacter);
  
      var str1 = arr.contents[0];
      var str2 = str1.match(/^\S+/);
  
      return str2;
  }
  

  My problem is that I can't get the content- str1 - by script. However, I can see in the data browser that it is there. If I click on str1, it appears:

  

  If I type str1 in the Console, I also get:

• get the strings '? ' instead of strings stored in the db

  Hello
  
  I migrate an application from Weblogic 8 to 10 and Oracle 9i and 10g
  
  I question my database by calling a procedure stored that paintings of buildings of type which is defined like this:
  
  CREATE OR REPLACE
  TYPE 'XXXXX '. "' STRING_ARRAYTYP ' IS THE TABLE OF 40;
  
  I run a CallableStatement and get the berries via cs.getArray (stored in a java.sql.array).
  
  In the field of data debug mode, I get a byte []: [-120, 1, -2, 0, 0, 2, 93,-110, 1, 3, 0, 8, 50, 48, 48, 56, 48, 51, 49, 51, 8, 50, 48, 48, 56, 48, 51, 49, 51, 8, 50, 48, 48, 56, 48, 51, 49, 51, 8, 50, 48, 48, 56, 48, 51, 49, 51, 8, 50] 48-48, 56, 48, 51, 49, 51, 8, 50, 48, 48, 56, 48, 51, 49, 51,...]
  
  When I convert it to a string in debug mode, I give myself: "[special characters] 200505252005052520050525200505252005052" who are my data.
  
  but when I get the result set and I call rs.getString (2), I get a '? ' string (after rs.next () call of course)
  
  The application worked before we migrate.
  
  Any idea?

  '?' is the replacement for a character unknown character (in an unknown character) so I suggest you add orai18n.jar in your classpath. Is the jar of Oracle that supports all charset conversions. The JDBC jar does support a few games of characters.

• Function call for the ActionScript variable name

  I am tempted to call a function dynamically by using a string variable.  I know that to do this normally, I would use code like this:

  var functionName:String = '' + currentItem.id;

  var myData:Array = this [functionName] (parameter1, parameter 2, parameter3);

  However, my function is actually in another directory of flex/package called UploadApps.customUploadFunctions.  I tried this sort of thing:

  var functionName:String = '' + currentItem.id;

  var myData:Array = UploadApps.customUploadFunctions.this [functionName] (parameter1, parameter 2, parameter3);

  but it does not work.  Any ideas on how to call a function with a variable name in another package?

  John

  My suggestion is to stop using the methods at the level of the package. Just do static methods in a utility class as we do in the framework in the mx.utils package. Then you can easily call them UtilityClassName [functionName] (param1, param2, param3). Given that the programming in AS3 is 99.9% on classes, I don't know why AS3 allows even the methods package level.
