• How to detect the change in the value of the point?

  Hi all

  We want the list of all the goods that the customer chooses, TileList is used to display all the information about the goods and a custom component MyItem is used as ItemRenderer. Meanwhile, a tag is used to display the sum of all the goods. The hierarchy is simply like this:

  <? XML version = "1.0" encoding = "utf-8"? >
  "< mx:Application xmlns:mx ="http://www.adobe.com/2006/mxml"layout ="absolute">"

  < mx:TileList id = "tl" dataProvider = "{acGoods}" ItemRenderer = "MyItem" / >

  < mx:Label id = "labelSum" / >
  < / mx:Application >

  Here, acGoods is an ArrayCollection collection which I believe may be linked.

  The user can change price in MyItem directly, so no need to update the text of the label as well. I find that acGoods contains the last price. Now the problem is the text of the label remains the same. I tried to call the calculation function in set acGoods(), but it does not work.

  Please don't not event expedition sugguest because this is a simplified scenario based on only. If someone tell me how to implement this in conjunction fluxhing, it'll be very useful.

  Best wishes

  protected function get totalLabelText (): string {}

  for each i: var * in acGoods and so on

  return 'label calculated here;

  }

  Once you've changed something to invoke:

  Application.application.executeBindings (true);

  Hope it will work for you

• Detect the change of the value in While loop

  Hello

  I recently took a code example in examples of using Labview and I'm putting the analog output through my data acquisition card 4461 pxi. I want to have a continuous waveform, but being able to change the volume and the waveform will adjust automatically and be issued through the card.

  In the code, I have everything first to open a .wav file and write it. While playing continuously through the while loop, but I want the signal to change automatically when the volume is changed. I know that I should probably use a structure of the event but the while loop, I use to play the signal will never stop unless the user presses stop so it would play permanently in a structure of the event even when the value changes (I tried).

  So now I try to see if there is a way to make my time stop loop when the volume value.

  You must correct the issues (forget the events if you are not sure of them):

  1. If wire you the digital volume to the wall of the while structure, then the whole in structure only tell that one value that happens on the node and will not read new values.

  2. to read the new values, move the Volume Terminal inside any building (which will shock your other code that depends on it), or use a local Variable inside any node.

  3. to check if the value has changed, you must compare the value to the previous value. To do this, use a shift on the while loop register to store the previous value and then compare it to the new value with the function "not equal?". Wire the Boolean result of this to the conditional Terminal.

  A better way for you might be to wrap the multiplication and Analog Write function into the while loop so that you're constantly replaying the waveform and it's continuously being re-scaled by the volume value. This will mean your volume control is being continuously polled (once per waveform playback) and used to scale the waveform each time. You'll need to figure out how to stop, send and play the waveform once per iteration of the while loop by bringing the Stop VI inside too. 
  

• Need to default to null text string values and values digital leave as are

• Change the field values of multiple text searching a word/words in their name.

  Hello

  So in my document, I load all the text fields roughly the same name than just with slight variations in their name.

  For example:

  FldTxt

  FldTxt1

  P1. TemplateName.FldTxt

  P1. TemplateName.FldTxt1

  ... Etc.

  The way this works is that each individual text box represents a parameter for a single element, so in this case there are 4 products.

  Is the way in which these parameters are selected, the user presses a button that generates a copy of a template page.

  On this page are a group of checkboxes, buttons and drop-down lists, these particular text fields display the value of a drop-down list.

  This is so that when the user has finished with the generated page, it can be removed and all the information is stored on the main page for later in the process.

  Because of how the elements of work means that fields can either displays a 'None selected' or option selected, BUT they cannot stand by the option that was selected.

  For example;

  FldTxt "none".

  FldTxt1 "selected Option2.

  P1. TemplateName.FldTxt "selected Option2.

  P1. TemplateName.FldTxt 'None Selected '.

  I hope this explains the theory behind it.

  So I wonder is what I could put these text fields values by searching for a keyword in their name? For example. If the field has "FldTxt" in its name, and its value is not equal to "None Selected", change its value to the value of the drop-down list of the most recent.

  The reason why I want to do it in this way is because there is no predefined number of these text fields, there might be only 2 or 200 because it depends on the number of items in the form.

  So I imagine it would go something like this;

  for (var i=0; i<this.numFields; i++) {
      var f = this.getField(this.getNthFieldName(i));
      var nameSearch = //search for keywords in a field name
      var dropdown = //the name of the dropdown
      if (f.nameSearch == "FldTxt" && if f.type = "textfield") {
          if (f.value !== "None Selected") {
              f.nameSeach.value = dropdown.value;
  

  My apologies if the syntax is incorrect or even impossible, but I don't know exactly what I'm asking check I just know what would be the outcome.

  I know that we can search for words in a document so I wonder if it is possible for domain names

  Your code is not quite correct. If I understand this code should do the trick (you may need to adjust the names of fields and values, however):

  var nameSearch = "FldTxt";
  var dropdown = this.getField("Dropdown").value;
  for (var i=0; i

• Change the default value for new messages of the 'paragraph' in "text" format the answer currently online because it does not work

  The answer currently online for this problem said to follow the sequence "tools-options-composition" and then change the default value, but this sequence "tools-options-composition" does not exist in Thunderbird (at least in the version I have, 45.4.0). Under 'tools', there is no option 'options... '

  It can depend on what menu you look and which operating system you are using.

  Tools | Options | Composition refers to the menu bar on top old.

  You can use alt or F10 to make the menu appear temporarily. Go to the view of . Toolbars and check the boxes if you want it constantly on the show.

  If you use the button 'Menu of the Application' new fashion (with three horizontal lines - see the attached picture) then it's probably Options | Options | Composition -I say 'probably' because I'm on Linux where 'Options' are replaced, I think that, by "Preferences". Another complication with this infernal Application Menu is that different things happen depending on whether you click or hover. Place the cursor on the Options of the first and the second appears after some time.

• Convert a Boolean trigger in the text string

  Hello

  I would like to know if it is possible to convert some text buttons in a single variable text string.

  Let me try to explain:

  I have 3 buttons: Simulation, send, Quit

  Now, I want to use a case structure, in which it is possible to switch between these 3 options.

  So if you press the button for a second, I would have a string of text with the text: send.

  If I press Quit, having to turn into Quit, text string even if I can connect this string to the structure of the case.

  Is this possible? It sounds easy, but I can't figure out how do it in a simple way.

  How I did it: Boolean convert (0.1), these values multiplied by a number,

  for example (1,2,3), but to make a deal with (1,2,3) structure and write the right text in a text string.

  But I think it can be done much easier, isn't it?

  Thank you!

  Hello

  Check the attached VI. I think this should help you. The mechanical action of the buttons are "switch until released. You can change it according to your requirement.

  The second example uses the Structure of the event.

• Position control text string bug

  Hello again all you posters useful forum!

  I have a strange bug for a control of the chain.  A sort of property has been set which causes the text it displays justified right as usual until what you press a button in the control.  Then the text jumps around 3 characters to the left.  By clicking on the right side of the new end text positions the cursor at the end of the text.  If I save the VI, the text jumps to the right.  Weirder yet, if I just hide the front panel of the VI with another window, when I discovered the text is on the right side once again.

  When I click in the text box with the mouse to position the cursor, the text does not move, but the cursor will only insert inbetween where the characters go when they jump to the left, where they are currently.  This highlighted the same behavior (see screenshot where I double-clicked in the control to highlight all of the text).

  I copy / pasted this control channel in a new VI with no logic, and it behaves in the same way.  So I guess it's a kind of property that I put at some point, but I can't understand it so I can stop doing it in the future (which is also the reason why I'm not only replace my order with another control of the chain and move - I don't want a new to get damaged in the same way).  I have attached the new VI for your reference.

  Control is updated the value that I type, and in my original VI (which I can't post, unfortunately), I have two cases of the event who get its updates of the value.  We seek a change in the value of this control, check if it is more than 12 characters and if yes what bands more than 12 characters and then it passes through the VI uppercase in and assigns the resulting string in the control.  The other looks for a value change parent of the control cluster, then takes the control reference that result and goes to a VI record KeyFocus and TextSelection property values, defines "BOLD", the blue police false KeyFocus, changes, then sets the KeyFocus and TextSelection values (in that order).   I have to take off bold KeyFocus, I discovered.

  Any suggestions as to what may be the cause of this would be appreciated.  Thank you!

  -Joe

  I bet that the text is right-justified.  Select the text, go to the menu drop-down font, select the option justify-> left and see what happens.

  Edit: interesting.  Out, tried changing the left justification and then right again seemed to fix it.

• To detect a change in a Variable?

  Hi all

  I can detect a change in variable (a string of data)?

  I do an AS2 SWF (level 7 Player) with navigation of the combobox control.

  I have a page name variable that I change from outside the SWF with the Director and Authorware using (I think) FlashVars.

  The variable (internally) is set by default when SWF is initialized.

  Authorized external variable values are always one of the combobox data field values.

  The combobox default variable is not always the index 0 (zero) position. Or the order of the data or the other.

  The variable can be modified internally in combobox nav used to independent navigation of the external variable. -It works

  When the nav var shared changes of the external source, the ComboBox must change for the variable game data to combobox corresponding. That's what I'm trying to do.

  I can change the drop-down list Configuration programmatically (index), but failed to recognize him as a change event. Or tell him by programming

  The combobox control can be selected by the data variable, or is the only option to use the index (loop index values to match the variable data field)?

  And update the selection combobox (and therefore the nav page) by triggering a change by programming event?

  Detect the var itself without the OnEnterFrame turn change is my goal - if it even works in the version I use (flash palyer 7).

  Thank you

  You can use watch(). I have not used for some time, so you will need to check the documentation.

• Detection of changes in PCI-6509 missing first data entry

  Hello

  I have two 6509 cards in separate computers, connected to each other. I use six lines, with one channel for each line, to send signals between the two boxes.

  I used the driver NOR-DAQmx 8.0.2 on SUSE Linux, coded in C.

  Starting by examples of digital I/o that I did a card pass in four lines and the other card received the signal, using the detection of change on the falling edge only, with the lines reversed.

  To send a signal it took the value 1 on this line, using digital lines of writing and then set it to 0 using the same function.

  If I send 4 signals, apartment of 100 ms, 1 on each line. The recipient will detect all four edges of falls, but the function of reading digital lines (in the recall of events highlights registed) returns zero for the first detection. I read only one sample of each line. Once that happens all seems fine.

  I read that more than a sample for the first digital reading for function call?

  What I have to do my signal longer, for the moment it comes to 150us? I can do this with an expectation in the code. I can afford it to streatch for about 1 ms, but it's always with this kind of treatment.

  Is there some call the initialization to get the driver to initialize the internal memory or something? (Maybe it's my wrt slow code, but I don't see how, there is almost nothing.)

  Thank you

  I think we arrived at the conclusion that this card cannot detect as close as 450ns interruptions. The API does not quickly that detect enough them between the interruption and the call to read data lines.

  It seems that we should have brought a card counting rather than a map of interruption.

• Reinvest a presentation Manager and detect any changes in size

  Hello

  I am trying to create a user interface that mixes elements I draw myself with native widgets and I do this by substituting the painting and drawing to an image in the background before drawing the fields themselves.

  To position the fields, I created my own Manager and position fields in absolute position based on my own component positions. For the base case works very well...

  When I type in a field, it grows, I do not detect this growth so I can not ebb the user interface. How can I detect a change to the default size of the field? I followed the field muddy/Sales status but that doesn't seem to help here is a picture of my test case, white in the middle is a native field and find it me difficult to follow its growth in real time:

  

  When I start the native UI scroll fields remain in place, I tried calling invalidateLayout, but it throws an exception? How to trigger the IU blackberry to call sublayout again?

  That's what I mean fields are now on top of my drawn text box:

  

  Thank you

  Shai.

  Yes, I noticed that you implement LWUIT. Two big thumbs up!

  First of all - don't spend just a new Manager (...) as a parameter in your full screen (I hope you meant that when you wrote FullCanvas).  Create a handler that is personalized with its own sublayout() and do the work there. In this way, you will be able to instantiate this Manager custom rather than writing the same code over and over again.

  Second - substitute object it inside the Manager, not the screen.  Not necessary, but once again - for the best control.

  Third - It's weird that sublayout of your Manager is not called automatically, but you can force it anyway:

  // in your MyClass:
  protected void sublayout(int width, int height) {
    layoutDelegate(width, height);
  }
  

  Have not tested but it should work.  This way, you should be able to rearrange and re - position your fields in the same manager that has all the knowledge, he needs.

  One problem remains, though - how are you going to partially show these fields when they slide to the edge of the screen?  I hope that you can set negative positions for them. Documentation for the manager class specifies all IllegalArgumentException on negative x and y in setPositionChild, so you might be lucky .
