• Why not use the static methods

  Hello world
  
  I was informed in a previous thread to avoid using static methods it was possible.
  Why is it, could someone please tell me a little more about this? Are there best practices, concepts on this?
  
  Thanks in advance,

  Hi Lemonbottom,

  The rule I used generally goes like this:

  If the method does something that I can use without the object containing it instantiate, then it can be made public static.

  In the previous examples, I had various foods. Apple might have a method called "getCaloricContent" that returns the number of calories in an Apple. I don't need an actual Apple to get this information, so I do static. However, if I want to Breathe() an Apple, then I need to build an Apple to do this, so static would not be appropriate.

  It is a loose guidance to help you get started. Try to avoid as much as possible of static methods. They add an extra dimension (often unwanted) to unit tests. It's not so say it is not a proper use of static methods.

  Once you've got your head around this concept, consider the model Singleton, who, in most cases, eliminates the need for static methods of learning.

• XMLFile parameter is not supported by Oracle APEX, please use the setXMLFile() method

  "XMLFile parameter is not supported by Oracle APEX, please use the setXMLFile() method.

  I created a test web app in apex.oracle.com to try a few things. I created a Flash 2D pie chart in a Web page, and it seems to make very well. But before rendering, I get the error message above, on the region of graph for 1-2 seconds.

  Can anynone tell me what means the error message above and why I'm getting this. I do not use a custom XML part. Has not changed the default settings of the chart area.

  I could see above the error appearing clearly since the apex.oralce.com is so slow... and graphics region takes awhile to load. Otherwise I could not have noticed. It happens in the IE8 and Google chrome.

  Oralce Apex 4.2.5.00.006 (https://apex.oracle.com)

  Google Chrome 34.0.01847.116

  Internet Explorer 8.0.6001.19518

  Can anyone help please. I'll try to become a test application setup dispalying this awhile earlier error message.

  I used HTML5 graphics in apex 4.2.0.00.27 in my office in my real application workspace. Most of my users still use IE8. HTML5 graphics all appeared well in their IE8 browser. One fine day, some parameters must be changed by my network administrator or soemthing else could have happened. I have no idea. My webapplication HTML5 graphics disappear IE8 users. IE9 users had no problem. I contacted our IT support staff of any changes to security settings that day, or earlier. Absolutely no help from my frustration. I have to change maps of my application (only about 6 of them) to the Flash graphics to overcome this obstacle. This is the story behind why I use Flash cards. If anyone has experienced a similar problem in IE8 HTML5 graphics please shed any light for me... This problem may be nothing to do with the "XMLFile parameter error message', but I'm not sure.

  I updated Firefox 2 days after seeing the message that I was not using the latest version.

  Why not in the list of countries, the Azerbaijan and the Georgia? I am a citizen of Georgia, but currently working and living in Azerbaijan.

As I said, I currently have in the territory of the Azerbaijan can't use Visa and Master Card and also problem with cards issued in Azerbaijan! What is the reason, can you explain?

  Hello

  It is a community of support based on the user, though I'm afraid that nobody here can speak you either the reasons for decisions from Apple or whatever plans unannounced Apple (for example, if and when pay Apple will launch in a given country).

  If you are wanting to see pay Apple throw in Azerbaijan and Georgia, you can let Apple know here:

• To access the properties of an Error Message When you use the DisplayRunTimeErrorDialogEx method

  I have a reminder that displays the standard runtime error dialog box using the method Engine.DisplayRunTimeErrorDialogEx of custom error. http://zone.ni.com/reference/en-XX/help/370052H-01/tsapiref/reftopics/engine_displayruntimeerrordial....  The parameters of this do not allow me to specify information about the error message available (via the properties of the stage of the appeal of error).  However, when built-in bed in treated TestStand display dialog runtime error through its methods of error handling he managed to fill in the details about the error.

  Anyone know how I can fill in the details and the error code from the dialog box fields when you use the DisplayRunTimeErrorDialogEx method to call it? See attached screenshot by one example of what I get when I use this method.

  Kind regards

  David

  Doug is correct; each sequence in the call stack has its own sequence context, so if you just "ThisContext" for the sequence context parameter, you provide the framework for the error callback, which has no error.  To access the context of the sequence that wrong, you use the caller property to get to the next level in the call stack, for example:

  RunState.Engine.DisplayRunTimeErrorDialogEx ("error Dialog", ThisContext.Caller, 0, False, False, False, False)

  I hope this clarifies!

• Legend of Java in OSB not showing the available methods

  Hello
  
  I made a simple jar which contains a class with a static method that connects to our active directory. I use the spring to connect to the ad. The jar is built using maven. When I build the jar, I copied into a directory of Jar in my project of OSB. I created an action JavaCallout in which I can choose the pot, but it does not recognize my static method... There is no methods I choose!
  
  Can someone maybe tell me what's not here?
  
  I have compiled the jar using jdk1.5. IM using 11G ps2. The method takes a string as input and returns a list.
  
  Thanks in advance!

  try to use the Web Console of OSB directly, it is VERY stable and well tested. Here, you have option explicit to create a resource JAR - you can't fail.
  Once do you operate in the Web Console, just the sbconfig.jar to export and import it into Eclipse.

  Honestly when I need to do something that is not the Message flows edition, I much prefer the Web Console, it is very strong (I can't say the same of the eclipse).

• How to use the find method to search for multiple items in a single paragraph?

  I'm desigining a script to find all instances where ctrl + b and ctrl + i are applied to body text and then replace the format of these characters replaced with chartag italic or bold.  Here's what the script is supposed to do:

  1. put the find method in a while loop that overrides seeks format character.
  2. If a substitution of format character is found, pass the text range returned by the find method and the CharPropsChange flag in the GetTextForRange method.
  3. Use a Boolean comparison between the idata of the text element to the angle of character and character constant weight.
  4. What that is the boolean is set to true, and then use the SetTextProp method to set the properties of the text range for the italic or bold character tag properties.

  This script works on the substitution of format first character found however it ignores other substitutions in the same paragraph. The cause of this is that the while loop updated the line of text control used by the find method for the following paragraph in the stream. I think I need to add an inner loop that runs through all the text in a single paragraph, where teaching iteration the loc text used by the find method is based on the same paragraph, but the offset is changed. I don't know how to do this.

  function removeOverrides (RPSC)

  {

  var vDocStart = pDoc.MainFlowInDoc.FirstTextFrameInFlow.FirstPgf;

  var vBoldFmt = getCharFmt (RPSC, "Bold")

  var vItalicFmt = getCharFmt (RPSC, 'Italic')

  initFA_errno ();

  While (FA_errno is constant .FE_Success)

  {

  var vTextLoc = new TextLoc(vDocStart,0);

  var vFindParams = findOverrideParams (CDRP);

  var vTextRange = pDoc.Find (vTextLoc, vFindParams);

  If (vTextRange.beg.obj.ObjectValid ())

  {

  var vTextItems = pDoc.GetTextForRange (vTextRange, Constants.FTI_CharPropsChange)

  If (vTextItems.length ==! 0)

  {

  If (vTextItems [0] .idata == constant .FTF_WEIGHT)

  {

  pDoc.SetTextProps (vTextRange, vBoldFmt.GetProps ())

  }

  If (vTextItems [0] .idata == constant .FTF_ANGLE)

  {

  pDoc.SetTextProps (vTextRange, vItalicFmt.GetProps ())

  }

  } else (Log (vLogFileName, ' \nERROR: none of the items were found in the table in text format but alternative size were found: ' + pDoc.Name))

  }

  vDocStart = vDocStart.NextPgfInFlow;

  }

  }

  function findOverrideParams (RPSC)

  {

  var vFindParams = AllocatePropVals (1);

  vFindParams [0].propIdent.num = Constants.FS_FindObject;

  vFindParams [0].propVal.valType = Constants.FT_Integer;

  vFindParams [0].propVal.ival = Constants.FV_FindCharacterFormatOverride;

  Return vFindParams;

  }

  Another approach (which is what I usually did) is after the first search to set vTextLoc = vTextRange.end

  Whatever it is, you might consider moving your initialization of vTextLoc and vFindParams outside the while loop. The settings do not change, why redefine them for each search?

• How to use the find method to search for character format substitutions and FMP?

  I strongly suspect that I should be able to use the find method to search for paragraph substitutions and format as these options are available in the Find dialog box. However, because of the excruciating Extendscript documentation from Adobe, I not was able to find the key pieces of information that I need. I found these constants:

  • Constants.FV_FindPgfFormatOverride
  • Constants.FV_FindCharacterFormatOverride

  But he has literally no information about them. It is not yet a definition, so I'm actually just a guess. However, I think that I need to somehow use these constant within the parameters of the Find method. Any ideas on how to do it?

  You're right, there are still some bugs to work out of the documentation, although it has already improved since I started w / Extendscript last summer.

  Find two constants must be defined as the ival for a PropVal FindObject, for example:

  var myDoc is app. ActiveDoc;

  var docStart = myDoc.MainFlowInDoc.FirstTextFrameInFlow.FirstPgf;

  tloc var = new TextLoc(docStart,0);

  var findParams = AllocatePropVals (1);

  findParams [0].propIdent.num = Constants.FS_FindObject;

  findParams [0].propVal.valType = Constants.FT_Integer;

  findParams [0].propVal.ival = Constants.FV_FindCharacterFormatOverride;

  myDoc.Find (tloc, findParams);

  Depending on what you're trying to accomplish, you can also take a look at the property FormatOverride of the Doc, bmp and item objects.

• Using the addEventListener method

  I want to put an addEventListener on a group of radio buttons for any button is selected the same function is executed.  However, the function can you use a term like currentTarget to tell which button has been selected?  I know with actionScript, you can use MouseEvent.CLICK in the listener then event.currentTarget service, but this doesn't seem to work.  The listener doesn't like 'click' and everything I try with currentTarget generates a run-time error.  I know that I can use the function onClick for each button, but I was wondering how to use the addEventListener method.  For some reason, I still have a horrible time, understand the documentation from Adobe.  It comes to PS CS3 & CS4 PS.  Thank you!

  Here is an example of adding an event handler for a control that does not already have a built-in Manager:

  createDialog = function ( ) {
     var dlg = new Window( 'dialog', 'Image Mouse Event Example Script' );
     var i = ScriptUI.newImage( new File('/c/k.png'));
     dlg.image = dlg.add ('image' , undefined,  i, {name:'temp'});// also accepts jpg
     dlg.btnPnl = dlg.add( 'panel', undefined );
     dlg.btnPnl.orientation = "row";
     dlg.btnPnl.alignment = "right";
     dlg.btnPnl.preferredSize [ 80, 80 ]
     dlg.btnPnl.okBtn = dlg.btnPnl.add( 'button', undefined, 'Ok', { name:'ok' });
     dlg.btnPnl.cancelBtn = dlg.btnPnl.add( 'button', undefined, 'Cancel', { name:'cancel' });
     return dlg;
  };
  initializeDialog = function( w ) {
     // Set up initial control states
     ScriptUI.events.createEvent('MouseEvent');
     w.image.addEventListener ('mouseover', btnMouseEventHandler, false);
     w.image.addEventListener ('mouseout', btnMouseEventHandler, false);
      with ( w.btnPnl ) {
           // The Ok and Cancel buttons close this dialog
           okBtn.onClick = function ( ) { this.parent.parent.close( 1 ); };
           cancelBtn.onClick = function ( ) { this.parent.parent.close( 2 ); };
        }
   }
  
  runDialog = function( w ) {
     return w.show( );
  };
  var win = createDialog();
  initializeDialog(win);
  runDialog(win)
  
  function btnMouseEventHandler (event) {
       try {
            var m = event.type// 'mouseover or mouseout
            if ( m == 'mouseover' ) win.image.icon = new File('/c/t.png');
            if ( m == 'mouseout' ) win.image.icon = new File('/c/k.png');
       }
       catch (e) {
       }
  }

• How to set the position and size of the façade using the FPRunTimePosRunCustom method in a c# application?

  How to set the position and size of the façade using the FPRunTimePosRunCustom method in a c# application?

  I found a solution! -Set the size and position of the façade with the help of the

  File > VI properties > window running Position (in category list) > custom (in position of menu drop-down).

  then just accept the current position and size (leave the boxes checked) or set values you want directly (uncheck the boxes and fill in the numbers), or physically position and size the façade and use, the "set to current location" button and press "set size" current All that is easier for you.

  OK so it does not make use of the method VI Methods (Active X) FPRunTimePosRunCustom ([Position], [Size]) but if labview want to make him difficult to use then other means must be found.
