• 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!

• 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.

• Why not use the static methods - example

  Hello world
  
  I would like to continue the below thread about "why not use static methods.
  Why not use the static methods
  with the concrete example.
  
  In my small application, I need to be able to send keystrokes. (java.awt.Robot class is used for this)
  I created the following class for these "operations" with static methods:
  

  public class KeyboardInput {
  
       private static Robot r;
       static {
            try {
                 r = new Robot();
            } catch (AWTException e) {
                 throw new RuntimeException(e + "Robot couldn't be initialized.");
            }
       }
       
       public static void wait(int millis){
            r.delay(millis);
       }
       
       public static void copy() {
            r.keyPress(KeyEvent.VK_CONTROL);
            r.keyPress(KeyEvent.VK_C);
            r.keyRelease(KeyEvent.VK_C);
            r.keyRelease(KeyEvent.VK_CONTROL);
       }
  
       public static void altTab() {
            r.keyPress(KeyEvent.VK_ALT);
            r.keyPress(KeyEvent.VK_TAB);
            r.keyRelease(KeyEvent.VK_TAB);
            r.keyRelease(KeyEvent.VK_ALT);
       }
  
                 // more methods like  paste(), tab(), shiftTab(), rightArrow()
  }

  You think it's a good solution? How could it be improved? I saw something Singleton vs somewhere of static methods. Wouldn't be better to use Singleton?
  
  Thanks for your comments in advance.

  Maheshguruswamy thanks for the tips on the steps create a singleton of this class.
  Perhaps you could say also why do you say that it would be preferable to use singleton? What is behind it? Thank you!

  In short, it seems to me that a single instance of your class will be able to coordinate actions across your entire application. If a singleton should be sufficient.

  But who doesn't answer why he expected prefer a singleton instead of a bunch of static methods. Functionally, the two are almost identical. In both cases, there is that a single 'thing' to call methods - either a single instance of the class or the class itself.

  To answer the question, the main reason to use a Singleton on a class of static methods is the same reason readers much of not static vs static decisions: polymorphism.

  If you use a Singleton (and and interface), you can do something like this:

  KeyboardInput kbi = get_some_instance_of_some_class_that_implements_KeyboardInput_somehow_maybe_from_a_factory();
  

  And then everything calling public methods of KBI has to know that there an implementor of this interface, without worrying about what concrete class is, and you can replace some implementation is appropriate in a given context. If you do not need to do, then the approach of the static method is probably enough.

  There are other reasons that may suggest a Singleton - serialization, persistence, use as a JavaBean pop to mind - but they are less frequent and less convincing in my experience.

  And finally, if this thing keeps updated a State between method calls, even if you can manage it with static member variables, it is more in line with the OO paradigm to make them non-static fields of an instance of this class.

• 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 "clickTAG" method to track a banner?

  So I just did my first banner, then the company is will host the banner told me I needed to use the "clickTAG" method... so it gave me a link and said follow this, but I had a few questions

  Here is the link

  http://www.Adobe.com/resources/RichMedia/tracking/designers_guide/

  So I made a new layer called Tag click and place a button above and make the invisible button, then I added this script of Action which it

  on (release) {}
  If (clickTAG.substr (0, 5) == "http://www.ozarksfederal.com/") {}
  getURL (clickTAG);
  }
  }

  Ozarks Federal is the banner advertising company that I did... and that's where the Web site

  I think this is right, but I don't know how to test if it's just?

  Anyone have any ideas? Thanks in advance to all those who contribute or learn from this!

  As the guide says, what you need is:

  on (release) {
       if (clickTAG.substr(0,5) == "http:") {
            getURL(clickTAG);
       }
  }
  

  Basically, the company is able to set the "clickTAG" through HTML, i.e. by integrating property: "yourad.swf? clickTAG =http://wherever.com" the only reason for the verification of the http protocol: is to prevent users from allowing malware, using, for example, the javascript Protocol.

• Change the position of SWF using the load method

  Hello
  
  I am a new user of Flash, so I apologize in advance if this is a stupid question. I try to use the load method to load an external SWF that I made. However, the SWF file load in the upper left corner. How can I manipulate its position?
  (I want to position more in the Center?)
  
  Thank you

  must have loaded it in a correct support video? You can use the x and y properties of the clip support to handle the position. The SWF file must be loaded first, before that these properties are available. It is preferable to use the MovieClipLoader class to load the SWF file, you can use the onLoadInit event to manipulate properties.

• Applying the addEventListener method to the Clips using a variable for example appoints

  This project is in HTML5 Canvas using Javascript in Adobe animate.

  I have a lot of movie clip symbols of film, all with a single instance (for example name ('arms', 'head', 'leg', 'foot', etc.). I also have a display of graphics and text clip ("text") which has a keyframe labeled corresponding to each of these symbols instance names. When a symbol is clicked, I want the clip "displayText" to access the appropriate section.

  There are a large number of these clickable symbols in each of several animations, so I definitely want to be able to do this in a way auto-tableau, it is too many to write code for each.

  What I have is this:

  var objects = ['arms', 'head', 'leg', 'foot'];

  var clickObject = null;

  for (i = 0; i < objects.length; i ++) {}

  clickObject = (objects [i]);

  clickObject.addEventListener ("click", displayText.bind (this));

  }

  function displayText() {}

  this.displayAndSound.gotoAndStop (clickObject);

  }

  Console says "clickObject.addEventListener is not a function", and I have tried many variations of the scope, using onClick rather than a listener events, etc, etc. What I am doing wrong - something to do with the scope? Something to variables vs channels? Something to do with how javascript regarding instance names? Legally binding?

  I can get it works fine outside of the loop, using names of the current instance, fixed, so hopefully it's a clue to what goes wrong...

  Any help much appreciated.

  Look at what you do in the loop. You do not clickObject for an object reference, configure that you just want it set to a string value.

  Assuming that the objects are at the same level as the code, you should do instead:

  clickObject = this [object [i]];

  Property accessors - JavaScript | DND

  In addition, your event handler probably don't do what you hope, that he will, because the value of clickObject will be just what you set to last in the main code. You may need to use the event object.
