  How to use paper in the latest version of Windows Live Mail?

  Version 2011

  Short answer: the stationery support has been removed from Windows Live Mail with the upgrade of v.2009 v.2011 back in 2010.

  Long answer: there are two solutions of workaround that you can try.

  • If you have a stationery .htm file, open it in Internet Explorer, and then select file > Send > Page by email (Alt - F E P). Save the message as a result as a .eml file and use it as a model for messages.
  • You can get in shape, for example a background color, to a HTML signature, then apply this signature to an e-mail message. Here's the one I use when sending pictures:
    

    
    

    Hello!

• How to use setFireActionForSubmit with the settings and capture the parameter

  Hello
  
  Can someone explain how to use setFireActionForSubmit.
  
  I extend the ShoppingCartPG controller. In the extended controller processRequest method I am adding a button to the table and implementation of the setFireActionForSubmit, so when the button is pressed it triggers the setFireActionForSubmit event.
  I need to pass the RequisitionLineId as a parameter which is present in the t associated with the ShoppingCartPG.
  
  I used the following code in the processRequest
  =================================
  ' public void processRequest (OAPageContext paramOAPageContext, OAWebBean paramOAWebBean)
  {
  super.processRequest (paramOAPageContext, paramOAWebBean);
  OATableBean otbRN = (OATableBean) paramOAWebBean.findIndexedChildRecursive ("ItemTableRN");
  OASB OASubmitButtonBean = (OASubmitButtonBean) paramOAPageContext.getWebBeanFactory () .createWebBean (paramOAPageContext, "BUTTON_SUBMIT");
  
  oasb.setID ("addnInfo");
  oasb.setUINodeName ("addnInfo");
  oasb.setText ("additional information");
  
  String pageName = paramOAPageContext.getRootRegionCode ();
  Hashtable params = new Hashtable (1);
  params.put ("param1", pageName);
  
  Hashtable paramsWithBinds = new Hashtable (1);
  paramsWithBinds.put ("param2", new OADataBoundValueFireActionURL (OASB, "${oa.encrypt.current.RequisitionLineId}"));
  oasb.setFireActionForSubmit ("addnInfoEvent", params, paramsWithBinds, false, false);
  
  otbRN.addIndexedChild (oasb);
  }
  =================================
  
  And I capture the event "addnInfoEvent" in processFormRequest method and trying to capture the RequisitionLineId I the past as a parameter.
  This is the code that I used in processFormRequest.
  =================================
  ' Public Sub processFormRequest (OAPageContext paramOAPageContext, OAWebBean paramOAWebBean)
  {
  super.processFormRequest (paramOAPageContext, paramOAWebBean);
  OAApplicationModule localOAApplicationModule = (paramOAWebBean) paramOAPageContext.getApplicationModule;
  
  String strEvent = paramOAPageContext.getParameter (EVENT_PARAM);
  
  If ("addnInfoEvent".equals (strEvent))
  {
  Number format = 0;
  try {}
  Format = new Integer (ClientUtil.getDecryptedParameter (paramOAPageContext, "param2"));
  }
  catch (System.Exception e) {e.printStackTrace () ;}
  
  String outmsg = "line ID:" + size + ":" + strEvent;
  throw new OAException (outmsg, OAException.INFORMATION);
  }
  }
  =================================
  
  But I'm not able to capture the RequisitionLineId I sent as a parameter.
  Can someone let me know what I am doing wrong.

  Hello

  Because your table is not a tip so table using a submit button approach will not work because it won't give you rank of reference and you will not be able to enter the id of the corresponding command line, instead you use an icon of the image, which can be created through customization. Let me know if you need help in the code.

  Thank you

• setCurrentState() substitute within the itemRenderer

  Well, as advised, I split separated the itemRenderer in a few VGroups, each with an includeIn = "stateName" attribute, in addition, there are a few defined States (im not not using standard names for the States). In the data property of the converter, I use a field of the object provided to decide which State to use, and I put the State using setCurrentState (stateName", false). When running, this will raise an error as soon as I have to refer to a component of a particular State (which must have been defined) because all references are null, so I googled and learned that I need some kind of substitute for setCurrentState() method and perhaps also the getCurrentState method. Don't know what im supposed to put into substitutions.

  Any ideas?

  Thank you

  All I see on my headers Ff are all sorts of legs that have no relevance to me, like 'how to stop Firefox from... '. "(twice), a few other symbols Ff and other"tabs"I don't know everything." All the do is filling up a bar line.

• How to use notes during the writing of my book with pages?

  How are used to write a book with pages of notes?

  You need the Apple EndNote plug-in for Pages v2.0and the EndNote 7.3.4 application (or later version) installed for compatibility El Capitan. With the plug-in installed and EndNote works, then you start Pages v5.6.1 and the Insert menu: reference EndNote is available for use. Launch Pages v5.6.1 prior to 7.3.4 EndNote and endnote reference entry in the Insert menu is not active.

• How to use HTML in the JavaFX controls?

  JavaFX supports using HTML in the text of the JavaFX controls? For example, in the Swing components:

  button = new JButton("<html><font face=arial size=16><center><b><u>E</u>nable</b></font><br>"
    + "<font face=cambria size=12 color=#ffffdd>middle button</font></html>");
  

  If not, we could find a workaround?

  Incorporating a WebView in a label for the HTML rendering

  
  

  A WebView is a node that displays HTML.

  Most of the controls implement labelled, or have elements that are labeled.

  One labeled has a method setGraphic (node) that allows you to establish the chart attached to the label of a node given (including a WebView).

  For example:

  WebView webview = new WebView();
  webview.getEngine().loadContent("Enable
  middle button");
  webview.setPrefSize(150, 50);
  
  Button buttonWithHTML = new Button("", webview);
  

  need to create a button with html in there (I didn't actually try running the example above).

  Aside time to start relatively slow on first use and overhead costs (which I can't quantify) to use WebView in this way, there are a couple of jira exceptional applications that are a bit annoying.

  RT-25004 allow transparent backgrounds in WebView

  RT-25005 favorite auto sizing for WebView

  You can vote for applications above jira or comment if such a feature is important to you.

  FXML/TextFlow/CSS Alternative

  Rather than using html in the labelled, TextFlow control support was introduced in Java 8, so that could be used instead.

  TextFlow also works well with FXML and css if you prefer to have the stuff in the TextFlow handled via a markup and a declarative style language.

  Open feature request

  There is a feature open request RT-2160 HTML support for text , which is currently scheduled for implementation in the initial release of Java 8.  I think the likelihood of it actually included it is zero percent, if it can be considered for a future version.  You can vote for the issue or add comments to it or provide an implementation if you are so inclined.

  Implementation considerations

  A possible implementation would be something that analyzes the HTML and then built a TextFlow HTML parsed according to the rules that are set out laborious mind-numbing detail in the specification HTML5 treatment.

  You can use an HTML parser relaxed such as the analysis of validator.nur (even though there may be others who would be a better fit).

  A simple implementation would be just to use the Analyzer in the jdk that is used for the swing controls, but that is hopelessly outdated.

  Perhaps, even simpler would be to accept only html strict entry and just use SAX to parse out, although things like validator.nu are too difficult to work with.

  Then, to the limited number of analyzed tags that you want to support (and you don't want to really not compatible with HTML5 all for something like this - otherwise use just WebView), create your TextFlow of the DOM who created your Analyzer.

  I wouldn't even both trying to handle most of the things in your html string in your application, stuff to do with style, fonts, colors, etc. These things were never in any case any good html and css is better for their handling, so just support things commonly used in modern day regular html (take a look at the HTML source "bootstrap" for example to see what it might be - if bootstrap uses her, I don't think not that you support it).  Things will support you are things around structure of document as lists, headings, etc. div blocks and cover the nodes - so only to implement this kind of important things and delegate all the rest to css where it belongs.

  Also, make sure that your implementation is part of the FXML so that you can easily integrate your html subset in a doc FXML.

• How REGEXP_REPLACE used to replace the part of the string?

  Hello
  
  How can I replace the portion of string as follows, I want to replace the space as by ' - '.
  
  SELECT
  REGEXP_REPLACE (superior ("' Laura bought stuff from 2000 USD on 12 September 2012 to KL and kl left on September 20, 2012"),)
  ' [0-9] {1,2} [^ 0-9](JAN|) FEB | MAR | APR | JUN | JUL | AUG | MS | OCT | NOV | DEC) [^ 0-9] [0-9] {4}',
  (','-') "REGEXP_REPLACE.
  FROM DUAL;
  
  the output will be like this
  
  Laura bought of the stuff of 2000 USD on 12-Sep-2012 of KL and kl left on 20-Sep-2012
  
  concerning

  Something like that?

  SELECT
  REGEXP_REPLACE('Daivd bought stuff by 2000 USD on 12 Sep 2012 from KL and left kl on 20 Sep 2012',
  '([0-9]{1,2}) (JAN|FEB|MAR|APR|JUN|JUL|AUG|SEP|OCT|NOV|DEC) ([0-9]{4})',
  '\1-\2-\3',1,0,'i') "REGEXP_REPLACE"
  FROM DUAL;
  

  Explanation:

  You group the parts of the date de-construct with (additional).
  You can use expressions, backreference \1 \2 \3 and add '-' between \1-\2-\3 signs.

  You should not user upper ('...') in the first parameter. If you cannot recover the original state of the letters.
  If you want to case-insensitive matching you should use 'I' in the last parameter of regexp_replace.

• How to use Groovy to the attributes of access on managed Beans?

  What is the best way to define view object Bind variable values that are not exposed by the entity object? More specifically, I have an entity with a values list object attached object. I need to set a value on the a Bind Variable views LOV ", which is not a value on line' oppose?

  You should not access properties of interface layer user directly from your model layer - because it would break the independence of the model using a specific user interface layer.
  Instead, expose a service method on the VO or AM that accepts a parameter and sets the binding variable - and then call this method in your user interface.

• Flex Mobile: View parent access within the itemrenderer component Variable

  I have several images in a list and I want to display 4 of them both on the screen with a provision in mosaic with the width of each image = 50% of the height and width of screen = 50% screen height.

  I was able to do this with the code below.

  < s:List id = "list1" width = "100%" height = "100%" >

  < s:ArrayCollection >

  < fx:Object id = "img1" img_url = ' assets/1 - 1.png' title = "Image 1" / >

  < fx:Object id = "img2" img_url = "assets/1 - 2.png" title = "Image 2" / >

  < fx:Object id = "img3" img_url = "assets/2 - 1.png" title = "Image 3" / >

  < fx:Object id = "img4" img_url = "assets/2 - 2.png" title = "Image 4" / >

  < / s:ArrayCollection >

  < s:layout >

  < s:TileLayout

  columnAlign = "justifyUsingWidth" horizontalAlign = "center" verticalAlign = "middle".

  paddingBottom = paddingLeft '0' = '0' paddingRight = paddingTop = "0" "0".

  horizontalGap = "0" verticalGap = "0".

  / >

  < / s:layout >

  < s:itemRenderer >

  < fx:Component >

  < s:ItemRenderer >

  "< s:Group width ="160"height ="240">" "

  < s:BitmapImage source = "{data.img_url}" scaleMode = "stretch" smooth = 'true' "

  Width = "100%" height="100%"/ >

  < s:Label text = "{data.title}" left = low "0" = "0" width = "100%" / > "

  < / s:Group >

  < / s:ItemRenderer >

  < / fx:Component >

  < / s:itemRenderer >

  < / s:List >

  However, I don't want to hard code the width and height values.

  I am able to get the screen specify height and width in the event viewAcivate of the view, as shown below.

  protected function view1_viewActivateHandler(event:ViewNavigatorEvent):void

  {

  ScreenWidth = screen.width;

  ScreenHeight = screen.height;

  }

  How to apply these values for width/height of the group properties in the itemrenderer?

  Something like...

  < s:ItemRenderer >

  "< s:Group width ="{ScreenWidth/2}"height ="{ScreenHeight/2}' > ' "

  < s:BitmapImage source = "{data.img_url}" scaleMode = "stretch" smooth = 'true' "

  Width = "100%" height="100%"/ >

  < s:Label text = "{data.title}" left = low "0" = "0" width = "100%" / > "

  < / s:Group >

  < / s:ItemRenderer >

• using methods of the builders class?

  I have a constructor that is quite complicated to ask my calling methods.
  I'm not sure whether to make these static methods.
  
  example #1
  class {Test}
  Object obj;
  
  Test() {}
  ....
  Initialize (this);
  ....
  }
  
  public static private Sub initialize (Test t) {}
  t.obj = new Object();
  doThis (t);
  doThat (t);
  }
  
  static private void doThis (t-Test) {...}
  static private void doThat (t-Test) {...}
  }
  -----
  example #2
  class {Test}
  Object obj;
  
  Test() {}
  ....
  Initialize();
  ....
  }
  
  private void initialize() {}
  obj = new Object();
  }
  
  private void doThis() {...}
  private void doThat() {...}
  }
  -----
  I understand the danger of use override-able for initialization methods, so take all the initialization methods are private.
  
  Directors of oriented programming OBJECT (as I understand them) suggest that instance methods are used to change the State of an object.
  Surely, the initialization changes the State of an object (forming / future).
  Yet, for some reason any when I call methods in constructors, I feel that these methods must be static.
  What is the right way of thinking?

  Yet, for some reason any when I call methods in constructors, I feel that these methods must be static.

  Why?

  A static method belongs to the class and not any instance of this class. Make a method to initialize a static object is contrary to this principle. If you are already inside the class object / what possible benefit can you get pass a reference to itself between all your methods?

  Here is another alternative, a block to initialize.

  class Test {
      {
          obj = new Object();
      }
  
      Object obj;
  
      Test() {
          // obj already initialised, no need to do anything here
          // other code
      }
  }
