• How can I indent a paragraph WITHOUT creating spaces above or below?

  I use Dreamweaver CS3 on a Macintosh G5 running OS 10.5.5.
  
  I chose a new document HTML (Dreamweaver opened as a CSS) and pasted the text in a MS Word document.
  
  When I 'dash' THROUGHOUT the text, everything remains the same except that it's ALL indented.
  
  BUT when I 'dash' single paragraph while paragraph is not only back, BUT there ALSO appears an extra space before and space after this paragraph.
  That this fact is inserting < blockquote > before and after the paragraph.
  
  How can I 'dash' a paragraph without appearing before or after the paragraph?
  
  Also is it easily possible from the page design?
  I tried to insert a tag by pressing the button 'tag' on the keyboard but that does the same thing as using the feature of "withdrawal" (which is also inserted spaces before and after the paragraph).
  
  BTW: I am a novice, so please try to make it as simple as possible.

  I wonder if what you are really wanting to do is dash all
  paragraph, not the first line.

  It is a collection of first line blah blah blah blah blah blah blah blah
  blah blah blah blah blah blah blah blah blah blah blah blah blah blah
  blah blah blah blah blah blah blah blah blah blah blah blah blah blah
  blah blah blah blah blah blah blah blah blah blah blah blah blah blah
  blah blah blah blah blah blah blah.

  It would be a paragraph indented blah blah blah blah blah blah blah
  bla
  blah blah blah blah blah blah blah blah blah blah blah blah blah blah
  bla
  blah blah blah blah blah blah blah blah blah blah blah blah blah blah
  bla

  If the second is what you want, use CSS according to the instructions to set the LEFT
  MARGIN (left margin) for the amount you want to put in the background, like 15px.

  If this isn't what you want, do what I did not write this.

• Run the Photoshop Action of the bridge on the raw files without creating a folder JPG

  I created a Photoshop Action that resizes and compresses an image (at 800 pixels at 24% quality). I want to run that Action of bridge on a selection of raw files. I have to do this, the bridge, select the images and select "tools-Photoshop-Image Processor". "In the window options 'Processor of Image', I put the folder to save the images processed, check the ' Action run" check box and select the Action but I have to check one of the 'file Type' (I check '"Save as JPG' with ' quality: 1" ") (it will run only if a"file Type"is selected), then click on 'run '. It then performs the Action on each image and I get the desired resolution file reduced and reduced the size of the file. The problem is that there also creates a JPG subfolder and creates another set of files also to the reduced resolution but the file sizes are larger than the game created by the Action.

  How can I run the Action without creating the subfolder containing the extra set of files whose size size JPG?

  I use v4.0.5.11 Bridge CS5, Photoshop CS5 v12.0.4x32 and Windows XP Pro SP3.

  Thanks to anyone who can help me.

  Batch processing, see options for the dialog box:

  Delete the file Open Options Dialogs (prevents the dialog box camera raw of opening)

  Delete (optional) color profile warnings

  Under Destination set to None (the files are backed up to where the files specified in the save for web (export) step and close step on the farm in action.)

  I use to go to Oracle PL/SQL client.

  Let's say your table than extractorders is the schema of database clientsproperty.

  As this pattern create a stored procedure that runs with the privileges of the customerschema. Having this procedure return a ref cursor For example

  create or replace procedure ReadExtractOrders( c in out sys_refcursor ) authid definer is
  begin
    open c for select * from extractorders;
  end;
  

  As this code executes with the privileges of the customer schema it can read the table belonged to this scheme.

  Now give execute rights on this process for the Joe database schema - and this pattern can create a cursor on the table of ExtractOrders , without being able to access or use directly or refer to this table. Read access to this table is therefore protected by a reliable code belonged schema customers.

  Learn about the AUTHID clause and how it can be used to differentiate the code approved and non-approved, which allows to PL/SQL code to run with different privileges than the demand for prescriptions.

• How can I mass move symbols with their trajectories without creating new keyframes?

  I want to move a large number of symbols at the same time if they are off centered or just need to be moved to see the different styles in the document, but I can't seem to move a lot of symbols at the same time, only a slexting of time their trajectories. It's quite annoying when I have points to settle at different times and re upholster everything one by one if I want to make things even by 1 px. Whenever I slecect all my symbols and try to move it's just creates a new keyframe they follow. Is there any tool or way select the symbols and/or their trajectories, move them without creating new keyframes?

  Hello

  There is no direct way to move all the symbols / beginning of the motion tweens to different images in total, but the following steps should help you make.

  1 Select a trajectory on stage, goto Properties Panel > menu Options (upper-left) and turn on - always show the trajectories.

  2 Select - change multiple images option in the timeline panel.

  3. adjust frame-markers in the timeline to display all your symbols, paths, etc.

  4. now that you see all your symbols and paths together, Select all and move them together. Or, use SHIFT + click to select the objects/paths of movement in a selective way and move them.

  Let me know if you have any doubts...

  Kind regards

• Can I create a PageDefinition without creating a Page

  Dear all,
  
  Help me, I can create a Page definition without creating the page.
  
  
  Concerning
  KT

  Thank you, ~ Abhijit, John, Puthanampatti, vinod_t_krishnan,-Arun, Frank. Now, I see very clearly the solutions. Thanks much for posting me the solution.

  Step 1.

  Generate the XML file and add the following inside the XML file.

  
  
  version = "11.1.1.52.35" id = "test1PageDef".
  Package = "Oracle.kt.testing.View.pageDefs" > / / This is the name of the package.

  Step 2.
  Save Page to DataBindings.cpx Def

  
  
  path="Oracle.KT.testing.view.pageDefs.test1PageDef"/ >
  

  Step 3.
  Restart JDeveloper,
  After reboot, JDeveloper show my XML file as the Page with its symbol definition.

  Note:
  In my project, I need to create more than 10 excel workbook, but not need to display as a Page. . I think that when we used the Page definition and remove all the components of the UI here and leave as empty page jspx. After we deployed the application to the server, maybe all the white page will hold certain amount of space on the server. Looks Like, create single Page definition of Excel workbook features ADF :)

• Using the function PLSQL return Record Type Index of Tables in ADF

  I have a PLSQL function, a return type. My ultimate goal is to take this binary integer index Table and print it on the screen...

  CREATE OR REPLACE PACKAGE my_pkg IS
  TYPE t_col IS RECORD(
  i NUMBER,
  n VARCHAR2(30));
  TYPE t_nested_table IS TABLE OF t_col;
    FUNCTION return_table RETURN t_nested_table ;
END my_pkg;

  
  

  OPTION 1:
  

  1) has anyone got best practices to accept plsql RECORDS returned by a function?

  Here is an example.

  http://adfpractice-Fedor.blogspot.SG/2013/01/working-with-PLSQL-procedures-in-ADF-BC.html

  But it will be a lot of work... first of all accept the results in a loop... then store in a temporary storage can be a few VO or global temporary table and then display them on the page

  
  

  OPTION 2:

  Using the functions PIPLELINED and use in the select statement.  While I can use this select statement in the SQL query to create VO... and drag and drop the VO...

  CREATE OR REPLACE PACKAGE my_pkg IS
  TYPE t_col IS RECORD(
  i NUMBER,
  n VARCHAR2(30));
  TYPE t_nested_table IS TABLE OF t_col;
    FUNCTION return_table RETURN t_nested_table PIPELINED;
END my_pkg;

  
  

  select * from table(my_pkg.return_table);

  
  

  Wow... I'm so smart! .. really possible?  who is the best/possible/recommended option?

  I'm sure that will be the question most read by many who wants to use PLSQL instead of JAVA to the treatment and CHOSEN to use only to display the output of the PLSQL functions or procedures.

  
  

  Thank you

  Do you mean the scope of the defined Type pkg will be finished?

  I created guy outside the pkg as 'Create Type' if it works in this case?

  Yes, level objects schema (created with "create or replace type...") can be used in java and this can work.

  I think that then the scope of this TYPE will remain until the user session passes.

  Object definitions is not worn, but have their bodies.

  So, if you instantiate the data level object type schema in a plsql function, scope of this object is this function.

  Of course, if you instantiate the object as a variable package, then life of this object is equal to the lifetime of the package (which usually equals life of session db).

• a function that returns the type with a table joint!

  Good day to all,
  I have a function that returns a type.
  
  so I select it as:
  Select * from table (function (param1, param2))
  
  now I want to combine this with a table so that the settings for the service we get from the join table. Is this possible? And how?
  I tried different options without success.
  
  something like:
  Select *.
  table table (function (b.column1, b.columnb) x), tablea b
  where x.a = b.col
  
  Is this possible?

• Is it Possible to use a function when you create a table?

  Hello

  Is it possible to use a function during the construction of a table?

  I would like to browse my data returned from the db and call a function. The part where I call the function "myFunction [i]" doesn't seem to work. How can I solve this problem? I need to put the function call results in the table.

  var i: uint;

  for (i = 0; i < dataArray.Length; i ++)

  {

  dgArray = [{name: dataArray [i] .name, Type: myFunction [i]}];

  }

  Thank you!
  -Laxmidi

  Hi laxmi,

  Yes of course it is quite possible to use a function when you create a table... In your code, you made some mistakes...

  You used hooks to call the function myFunction [i]... where you are supposed to use parentheses... myFunc (i)... and other you must push the object in the dgArray but yous hould not not attribute...

  dgArray = [{name: dataArray [i] .name, Type: myFunction [i]}]; This will result in only the last table iterates in dgArray...

  So you should write dgArray.push ({name: dataArray [i] .name, Type: (i) myFunction});

  Check out the code below...

  
  http://www.Adobe.com/2006/mxml"layout ="absolute"creationComplete ="init (); » >
  
    private var dgArray:Array = new Array();
  private var myDataArray:Array = [{data: '1', name: 'Robert'}, {data: '2', name: 'Nicolas'}, {data: '3', name: "Bika"}]
   
  private function init (): void
  {
  for (var i: int = 0; i
  {
  dgArray.push ({name: dataArray [i] .name, Type: (i) myFunction});
  }
  }
    
  private void myFunction(i:int):String
  {
  Return 'Type' + i;
  }

• I can't write CD on Satellite Pro P100-347

  I was recently bought a Satellite Pro P100-347 with Windows XP MCE installed as a desktop computer (the store didn't inform the person who has bought a laptop that was not networked). We have purchased a full copy of Windows XP Pro and booted from the disk, formatted the hard drive and installed XP Pro instead of the ERM and then downloaded and installed all the drivers on the Toshiba site.

  I had the "failure to obtain read handle" error starting but followed the recommendations on this site and removed the toshibarc.exe of the registry. Now, the only thing I still need is to get the CD of drivers, because even though I can play CDs and copy on their part, I can't write CD - if I put a blank CD in the drive and select the option to create the writable CD folder, I get an error that says ' D: / is not accessible. Incorrect function. "

  I downloaded and installed the DVD-RAM drivers, but I can't find those specifically for the CD. Can anyone help?

  Thanks in advance,

  Hello

  In my opinion, you should check the properties of the disk and click the recording tab.
  CD recording option on this drive must be marked.

  I moved files on "users / shared" on the imac 27 "my father Yosemite retina.  He got last June but was not able to migrate because of her old imac was in Florida and North Carolina.  So, I migrated the old imac again with time machine backup charges a few months after getting the computer.  Now, I'm trying to merge the 'old' on the new computer account with the migrated account 'new', I restored it with time machine from the old imac.  I thought I was smart "passage" large libraries of film and photo of users / shared and that the account migrated from old imac. (on the same computer again) But I have no write permissions for files on the migrated account.  And making matters worse, while I can't write to files, I'm still able to corrupt them trying to change permissions and try to load them with i-movie and what not.  So now, I have a 6 GB corrupted movie library and not backup.  I tried it duplication and corrupt also.

  So my question would be "why is it when I add to the new migration full privileges to user for these files, I always failed to write about them?  Now instead, I wonder if there is a way I can fix the corrupted film library file.  Film - I tried and failed on the double.    I tried available i-movie file to 'all' as well as the addition of the new migrated user full privileges to it.  While I was able to do it without error (it seems to take the changes) or the new migrated user or former user on the new computer can write to the file (i-film library) at this stage.

  Every article help I read says just to click on info and change the privileges for what I did.  So I'm pulling my hair out.

  Hope that I was not too confusing in the way that I want to talk about the two different accounts.

  Reset user - file property See post by Linc Davis

  You may need to restore the permissions on your user account. To do this, start on your recovery partition (hold down the command and R during startup) and open Terminal from the Utilities menu. In the Terminal, type: 'resetpassword' (without the), press return, and then select the admin user. You do not have to reset your password. Click the icon of your Mac hard drive at the top. In the list box below, select the user account that has problems. At the bottom of the window, you will see a box labeled restore Home Directory permissions and ACLs. Click the button to reset there. The process takes a few minutes. When you're finished, restart.
