• Save for web images look slightly blurry compared to other images that I see online

  Whenever I save a file in photoshop for the web as a png image, I see them get a little blurry and not very sharp. I did all the dimensioning and sampling etc. as far as I know. Yet, when I compared with other images that I see online, they don't look as strong. Is it just a fact that I need to add to my work, even if a large part of the time I work with vector shapes? Are not vectors supposed to be clean and crisp always?

  The blue image below is another person I know was made in Photoshop. My work is the red on the right. As you can see, it looks a little blurry.

  

  Any ideas or suggestions?

  The blue image was also created with more details in the foreground as sting in the Ribbon and more texture contours in the Ribbon.  That's why the Red Ribbon seems less detail and seems flat.  I don't see with my eyes less sharpness however the drop shadow and a low background noise in the Red image contrast color makes the Red image have less contrast and then the blue image with a high-contrast light blue background. The red background details are not clear I would like this or aim to have a look of sweet in the background. When there's no detail in the blue image background other maybe a bit degraded.  It has IMO a lot to do with the composition.

• Change an element of length of field data in the reports.

  Hi all

  I have to change a report based on a table element.

  The array element is 4 digits 8-digit alterd.

  In the report, the field is always 4 digits and I tried to give him the new length of the 8-digit database item.

  It will not work, I can not change the properties of the report field.

  How can I make it OK?

  Thanks for tour assistance,

  Cees cordially

  I found the solution by accident!

  I had to change something in the query where the field was in...

  By saving the request was generated and... the length of the field had changed to 8 digits!

  Kind regards

• change the length of field

  Using database Oracle 9.2.0.5 on Oracle Enterprise Linux and Oracle Report Builder 10.1.2.0.2 on Microsoft Windows XP Professional SP2.
  
  I have changed the length of a varchar2 column in my database from 4 to 8 and to update the fields that correspond to this column in my reports.
  
  How this is done?

  Open your query, add space and press OK... your domain should now reflect the changes made to the database.

  Normally the browser automatically resizes the selection list based on the content.

  What version of the browser / do you use?

  What theme?

  What model page/region?

  What form/article layout?

  What content does not match?

  (Basically the best way to get help with problems of this type is to reproduce on apex.oracle.com and see us actually...)

• Why oracle stores no length for CHAR, VARCHAR2, and other types?

  Hi friends,
  
  I was reading a book by Tom Kyte on the types of character data.

  +For character strings,Oracle will have a leading length field of 1 to 3 bytes, or when they are NULL they+ 
  +will be represented by a single byte value of 0xFE.+
  +If the length of the string is less than or equal to 250, Oracle will use 1 byte for the length.+
  +All strings exceeding 250 bytes will have a flag byte of 0xFE followed by 2 bytes that represent the length.+

  Can someone explain please why Oracle shops length here and where exactly is - it used by Oracle?
  For strings longer than 250 bytes, it sets a flag to 0xFE byte. What is the usefulness of this indicator byte and how is it useful?
  Is there anyway we can see the length bytes that are stored by Oracle? I tried with the DUMP function, but it is to show that the value of the length, but not the bytes it stores for her.
  
  Kind regards
  Anthony

  I think that Oracle chose 0xFF to represent a null value
  (a) Yes
  (b) should be 1 as another column can follow

• Starkey Halo 2 streaming quality, compared to other devices (especially to the Muse / SurfLink Media 2)

  I am considering buying a pair of hearing aids Starkey Halo 2 - and an iPhone to chase them! Does anyone have comments on the audio quality when streaming to the iPhone?

  I am particularly interested in how it compares to what you would get with a pair of hearing aids Starkey Muse, streaming from a media 2 SurfLink (which is apparently better than you get with the Starkeys of the Z series because of an improved codec).

  Comparisons with other devices (for example, Widex Unique + TV - DEX, or Phonak Audéo V90 + ComPilot II) are also welcome.

  My audi has said no, BUT if you "hear" something different, please advise!  Looks like a real missed opportunity for me!

• There are so many modules now that do the same thing, how can I say all the features of one add-on compared to others. I know I have way to much the same thing and need to get rid of the undesirables?

  can we get a comparison side by side the Add-ons. How can I say that ive got 2 or even 3 Add-ons that do the same thing? and how can I choose the one that fits my needs, so I can uninstall all others?

  There is no way to automatically compare the modules, you must manually check their characteristics.

• generated writing XML to a file after comparing with other XML

  Hello

  I made the comparison of the two XML now, I have an obligation to concat these two xml but also necessary to add the XML code with a status node that is after comparing the two displayed XML is Y or N, so if it is there then a node with

  < status > Y < / status >

  < of table > t1 < / table >

  then by completing the tasks that I have to write to a file

  declare

  p_emp_info CLOB.

  l_emp_tab xmlsequencetype: = xmlsequencetype();

  BEGIN

  I'm IN (SELECT id from emp WHERE emp_name = 'ABC') LOOP

  l_emp_tab.extend;

  SELECT XMLELEMENT ("ABCD",

  XmlElement ("ID", i.ID))

  IN l_emp_tab (i)

  FROM dual;

  END LOOP;

  SELECT XMLELEMENT ("EMP"

  XMLAGG (t.column_value))

  IN p_emp_info

  TABLE (l_emp_tab) t;

  -Dbms_Output.put_line (getclobval (1,2));

  EXCEPTION

  WHILE OTHERS THEN

  Dbms_Output.put_line(SQLCODE||) SQLERRM);

  END;

  I'm using this query, but it gives me an error that the expression is of the wrong type on this line {IN l_emp_tab (I)}

  I am unable to find the error what I'm missing here!

  You have changed the data type of I the example that Odie that gave you in

  repeating nodes using loop but when XML string concating then concating only last iteration of the loop FOr?

  In his case, I was a number.  In your code above, I have now is the set of rows in a cursor.

  You can rewrite your version to look like

  declare
    p_emp_info     XMLTYPE;
    l_emp_tab      xmlsequencetype := xmlsequencetype();
    l_pos          PLS_INTEGER;
  
    CURSOR c_info IS
      SELECT id
        from emp
       WHERE emp_name='ABC';
  
  BEGIN
  
    FOR r_info IN c_info LOOP
      l_emp_tab.extend;
      l_pos := c_info%ROWCOUNT;
      SELECT XMLELEMENT("ABCD",
             XMLELEMENT("id",r_info.id))
        INTO l_emp_tab(l_pos)
        FROM dual;
    END LOOP;
    SELECT XMLELEMENT("EMP"
                         ,XMLAGG(t.column_value))
      INTO p_emp_info
      FROM TABLE(l_emp_tab) t;
  
    --Dbms_Output.put_line(p_emp_info.getclobval());
  END ;
  

  You can use the % c_info number of LINES in the INTO clause, hence the l_pos.

  Or you can rewrite to be

  declare
    p_emp_info   XMLTYPE;
    l_clob       CLOB;
  BEGIN
  
    SELECT XMLElement("EMP",
             XMLAgg(XMLElement("ABCD",
                      XMLElement("id",e.id))))
      INTO p_emp_info
      FROM emp e
     WHERE emp_name = 'ABC';
  
    SELECT XMLSERIALIZE(DOCUMENT p_emp_info AS CLOB)
      INTO l_clob
      FROM DUAL;
  
    Dbms_Output.put_line(l_clob);
  END;
  

  Both produce the same XML file.

• By comparing the other OS Vista

  I'm trying to find a tool that details the OS installation procedures, orders, etc..  The tool for the job would be the detail of orders and procedures XP in a single column and have Vista controls for the same characteristics in the second column.  I was wondering if anyone has such a work tool or can point me to a site where I can find the information.  Any help would be appreciated.

  I don't know what commands are you talking about. Your question is too broad. There are many differences between XP and Vista and many similarities. There is a large amount of information on the way in which the operation of each operating system that you are available if you need to define your end goal closer.

  If you want to compare installation techniques, here are links detailing XP installs and install Vista. You can read through them and make notes on the differences.

• Did not update the field lengths

  All,
  
  I changed the lengths of field forms all day to IOM 9.1, and it does not update the actual column length when the form is activated. I came back to directly update to the sizes of the column in the database to get things to work. I missing something here, or are completely useless in IOM field length variations?
  
  S

  My experience is the same. You cannot change just reliable lengths using the client interface design.

  Slightly irritating and very dangerous if you don't know the question.

• Is it possible to calculate the number of two or more in the same field?

  What is trying to do is to caculate a number of pages of the book for a copy.

  For example I want to copy pages from 25 to 30, then the user will write 25-30

  the number of copies will be equal to sum = "30-25 + 1".

  and if the user write only a single number, the number of copies is equal "sum = sum + 1.

  Thus, user input will be like that "25-30, 45-60, 65, 67.

  I think using a table and one ',' split

  var sumArray = new Array();

  sumArray = sum.split(",");

  Y at - it all possible ways to do this?

  Thanx

  Hi, I think you can use a regular expression, but I would use a split as well, something like;

  var pageNumbers = TextField1.rawValue.split(",");

  var sum = 0;
  var isValid = true;
  for (var i = 0; i)< pagenumbers.length;="">
  {
  var pages = pageNumbers [i].split("-");
  Check for all elements of number
  If (! pages.every (function (element) {return (element == parseInt (element, 10)) ;}))}))
  {
  xfa.host.messageBox ("Please enter list separated by commas in number of pages, with a range separated by a dash, for example, 25-30, 45-60, 65, 67");
  isValid = false;
  break;
  }
  If (pages.length > 2)
  {
  xfa.host.messageBox ("Please enter a range of pages separated by a dash, e.g. \"45-60\ "" ");
  isValid = false;
  break;
  }
  If (pages.length == 1)
  {
  sum ++;
  }
  on the other
  {
  var start = parseInt (pages [0]);
  var end = parseInt (pages [1]);
  If (end<>
  {
  xfa.host.messageBox ("Please enter a valid page range separated by a hyphen with the start page in the first place, for example \"45-60\ "" ");
  isValid = false;
  break;
  }
  sum += (end - start + 1);
  }
  }
  If (isValid)
  {
  App.Alert (Sum);
  }

  Might need some more error handling but I hope will help you get started.
