• How to display the number of socket in the ListBox UI control?

  I want to display the number of socket in the Listbox control on execution. I use DisplayExpression method, set the entry as '% TestSocketIndex', but it does not work. This methond works fine if I connect the Combobox of UI control to ExecutionViewMgr.ConnectExecutionList.

  Is there a solution

  

  

  Hey wellsc,

  I have looked at this issue and ran into the same issue you described. I dropped the CAR 482840 for a developer study the matter further. Unfortunately, workarounds only I can think immediately would be to use a ComboBox control or to implement the functionality desired by using a native LabVIEW ListBox.

  Let us know if there is something we can do to help, or if you have other questions about how to implement one of the workarounds. You can still use this CAR number to check the status of the issue, as well.

• How to dynamically change the selection mode of the listbox control?

  Hello everyone

  Is it possible to change the selection mode of the ListBox dynamically?

  Both cases to the attached vi works the same way. I want the listbox to change the mode of selection by 1 point when the channel selected in the drop-down list box is SET.

  Can anyone help please?

  Thank you

  Simo

  There is a property for Listboxes node called selection Mode.

  Do not use the control Terminal in one case and a local variable of it in the other.  Moving the Terminal outside the structure of matter and son in the structure of the case.

• description of the pop-up window for the listbox items

  I want to show the information in a pop-up box, like moving the mouse on each item in a listbox control. How can we do?

  Hello

  You can try this,

  Get the following properties of the listbox control you

  -ContentRectPos

  -ContentRectBounds

  -CelHeight

  Create an eventloop with listbox: mouseMove

  Get the mouse position by using available inside the eventloop coords

  With this information you can determine on which element of the mouse is on.

• strange behavior of the listbox

  I have a listbox that is filled from the data in a table.  When new data are added to the view is forced into a window PopUp.  It is also the initial view of the application.  When the application starts the listbox is not populate.  After that I have add an element to the table from a PopUp window and push the view at the first sight, that the list appears with the new data.  If I take the line

  var myTransStringtring = data.toString ();

  Code of the list box loads when the application starts as it should.  I don't know why this line of code is causing the problem.  The list box must load with code or without it.  Here's the complete code:

  protected function view2_viewActivateHandler(event:ViewNavigatorEvent):void
  {
                  
  var myTransStringtring = data.toString ();
                  
  dbConnection varQLConnection = new SQLConnection;
                  
  var embededSessionDB:File = File.documentsDirectory.resolvePath ("myLists.db");
  var writeSessionDB:File = File.documentsDirectory.resolvePath ("myLists.db");
  If there is no such thing as a database writable, we then copy in the app folder so this writteable
  If (! writeSessionDB.exists)
  {
  embededSessionDB.copyTo (writeSessionDB);
  }
                  
  var dbFile:File = writeSessionDB;
  Try
  {
  dbConnection.open (dbFile, SQLMode.UPDATE);
  trace ("the database opened successfully");
  }
  catch (errorQLError)
  {
  trace ("error message:", error.message);
  trace ("details:", error.details);
  }
                  
  stmt.sqlConnection = dbConnection;

  stmt. Text = ("SELECT Nom_liste FROM the list ORDER BY Nom_liste");
  stmt. Execute();
                  
  Table of results: var = stmt.getResult () .data;
      
  var myAC:ArrayCollection = new ArrayCollection collection;
                  
  myAC.removeAll ();
                      
  for each (var objobject result)
  {
  myAC.addItem (obj.list_name);
                      
  }
                  
  myAC.refresh ();
  dbConnection.close ();
  myLists.dataProvider = myAC;
  myLists.selectedItem = myTransString;
  }

  Neil

  I thought about it.

  The line had to be moved under the fill listbox.

  myAC.refresh ();
  dbConnection.close ();
  myLists.dataProvider = myAC;
  var myTransStringtring = data.toString ();
  myLists.selectedItem = myTransString;

• How to add values to the Listbox in the ADF.

  Hello

  I have a listbox that is met when the user clicks an Add button then click on the Add button whenever the values are added.

  I have a textbox where the values are added

  < af:inputText

  label = "Categories".

  ID = "itcatg".

  contentStyle = "width: 100px".

  Binding = "#{viewScope.RegWoComp.CATG}" >

  < f: validator binding = "#{bindings." Categories.Validator} "/ >"

  < af:autoSuggestBehavior suggestedItems = ' #{bindings. " Categories.suggestedItems} "/ >"

  < / af:inputText >

  Add a button

  "< af:commandImageLink actionListener =" #{viewScope.RegWoComp.btnadd} "icon =" / plusimage.gif "id ="proud"/ >

  and you choose a listbox.

  < af:selectOneListbox id = "lstcatg" label = 'List of categories' partialTriggers = 'proud '.

  value = "#{viewScope.RegWoComp.lstboxcatg}" >

  < f: selectItems id = value="#{viewScope.RegWoComp.customList}"/ "lstselect1" >

  < / af:selectOneListbox >

  managed code the bean to populate the listbox control

  The list < SelectItem > customList;

  public void setCustomList (list < SelectItem > customList)

  {

  this.customList = customList;

  }

  public list < SelectItem > getCustomList()

  {

  return customList;

  }

  public void btnadd (ActionEvent actionEvent)

  {

  customList = new ArrayList < SelectItem > ();

  customList.add (new SelectItem (catg.getValue));

  }

  That's when I click the button remove new value is inserted but the values are not added. I tried to make a method from arraylist and then by calling the Add method, but then also the values are not attached.

  This is because you have an initialization list

  Declare your list like this

  List customList = new ArrayList();

  Instead of

  List customList;

• BRIGHTNESS: transparency and accelerate the departure of the fragments to end

  I have a simple glow effect, but I want to maintain transparency when

  I export this clip to the body so this effect is then on a different level.

  at this time the background is black.  Can I just turn on 'the transparency grid?

  Also the last pieces do not leave the area of the image rather quickly.  How can I speed up this part?

  In fact I would the explosion to start more slowly, then accelerates the end to get rid of the fragments.

  OK I see variance mass will do.

  "Gravity", I added the pieces still fall through the frame, but he got rid of them more quickly.

  Rather, they come out of the frame, as if there is no gravity.

  Thank you

  Steve z

  Steve Zeeeee says:

  Can I just turn on 'the transparency grid?

  Laughing out loud

  You will need to return to a format and a taking codec supported transparency. For example, go to QuickTime with the PNG codec and be sure that you set your render settings to be RGB + Alpha

• measure the actual page for each page size in the listbox

  Hi guys,.

  I'm trying to write a script that lists all the pages in the ListBox with 2 additional columns: width and height

  and stuck when trying to get the limits of pages for each page in the document.

  My result looks like this now:

  

  script no matter what I'm trying to get only the size of the 1st page and fill in all items.

  My code to get the size of the page above is:

  myDoc = app.activeDocument;

  page var = myDoc.pages [0];

  ...

  function myRealHeight() {}

  var Pbound = page.bounds;

  var pH = Pbound [2] - Pbound [0];

  var realHeight = [];

  for (j = 0; j < myDoc.pages.length; j ++) {}

  realHeight.push (pH);

  }

  Return realHeight;

  }

  I have tryied a few different ways but but always returned [object Page] or higher.

  I'm newbie in scripts, and if someone could help me will be great.

  Thank you

  (let me know if other parts of the code are required)

  Try this (sorry not tested).

  var myDoc = app.activeDocument;

  ...

  function myRealHeight() {}

  var realHeight = [];

  for (j = 0; j< mydoc.pages.length;="" j="">

  page var = myDoc.pages [j];

  var Pbound = page.bounds;

  var pH = Pbound [2] - Pbound [0];

  realHeight.push (pH);

  }

  Return realHeight;

• remove the icon of the ListBox?

  I am trying to remove the icon or image of the ListBox, but nothing seems to work? What I am doing wrong?

      var w = new Window ("window");
      lb = w.add ("listbox", [0,0,100,150], ["item1", "item2", "item3"]);
      var btn = w.add ("button");
      
      lb.items[1].icon = File ("~/Desktop/redSquare.jpg");
      
      // None of this is working... 
      btn.onClick = function (){
          lb.items[1].icon.remove();
          lb.items[1].image.remove();
          lb.items[1].remove("icon");
          lb.items[1].remove("image");
          lb.remove("image", items[1]);
          lb.remove("icon", items[1]);
          lb.remove(items[1].icon);
          lb.remove(items[1].image);
          }
      
      w.show();

  Yes apparently once the item has an icon specified, you cannot "unspecify" it (lb.items [1] .icon = null; or lb.items [1] .icon = void (0); > error).

  You can remove all items and re-create them with the necessary icons, or none.

  Another possibility is to create an empty icon (completely transparent) the same size of the other:

  var

  f = new File ("" ~ / Desktop/redSquare.jpg ' ").

  g = new file ("" ~ / Desktop/transparentSquare.png ' ").

  w = (this instanceof Panel)? this: new window ('window'),

  lb = w.add ("listbox", [0,0,100,150], ["item1", "item2", 'item3']),

  BTN = w.add ('iconbutton', not defined, f, {style: 'toolbutton', toggle: true});

  btn.onClick = function() {}

  for (var k = 0; k)<3; k++)="" lb.items[k].icon="(this.value)" f="" :="">

  };

  BTN. Notify();

  (o instanceof window)? w.Show (): w.layout.layout (true);

• Get rawvalue (index) of the Listbox using FormattedValue

  I have two drop-down menus with two different sets of data. a country and another with the profession.

  I have a listbox with all the possible country/profession together to form a formattedvalue. How can I get the rawvalue/index with the formattedvalue of two fields above.

  I will choose a country in particular and profession and then I need to get the index of this combo in the listbox.

  Any help would be appreciated.

  I solved my problems. Here is the code I have developed to do the job. It could be simplified a bit further, but it worked fine.

  I put it in the action of the entry.

  checkValue .rawValue = var [dropdown1]+ [dropdown2].formattedValue + «,»

  oArr var = checkValue.split (",");

  oList var = xfa.resolveNode (.somExpression[listbox with the values of index and concat]);

  var oListIndex;

  While {(oArr.length!=0)}

  oListIndex = oList.boundItem (oArr.pop ());

  oList.setItemState(oListIndex-0,1);

  }

  NOTE: You can add if statement to make it work only if these fields have values just before while the State.
