• Popping / crackling sound when the Satellite L650-1PQ is connected via HDMI

  Hi all

  I have recently connected my laptop to the TV via HDMI, and I hear his pop/cracking every time the music, video or games is played. I tested the speakers with my MP3 player and the Xbox, and there is no POPs or crackles when I'm with them.

  I've updated to the latest drivers from Toshiba, but it has not yet resolved the issue.
  Any help would be greatly appreciated!

  Care of my system is as follows:

  Processor: 2.66 GHz Intel Core i5 480M
  RAM: 4 GB DDR3 RAM
  OS: 64 - bit Windows 7 Home Premium
  Graphics card: ATI Mobility Radeon HD 5650

  > I have recently connected my laptop to the TV via HDMI, and I hear his pop/cracking every time the music, video or games is played

  The crackling is in from the TV speakers. Right?

  Can you hear the Crackle even using headphones or speakers for laptop?
  If not, then I think that this problem could be related to his driver.

  In your case, I would check the settings in the control panel-> sound-> playback-> audio digital-> set up

• HP Envy 15 J6Z08EA #UUW: disabling pop-up message when the connection warning me that I have disabled the connection of the fingerprint

  I want to remove an annoying message when connecting. I disabled the fingerprint reader, because it makes my games to the tab down whenever I accidentally touch the reader. And it is placed "below" on the left side of the keyboard (keys WASD, if you understand me) who thought that might be a good idea.

  Now I get these messages of connection warning me that the fingerprint is not enabled, every time I started the computer, make me when entering my password to start over from the first letter, so that my password is messy (if I had the password: 'password' that would make me write pass) , and then the popup would come, that I have to click down, and then if I write "word" it originally make my password 'wordpass' test, if you understand. So it's a manufacturer 'fault' I'm trying to fix. Any tips? Is the way to activate only the reader of fingerprints to be active during the connection and not when already connected. Or how to remove these popups WARNING when connecting.

• Notice when the user enters the field

  Y at - it code of CF I could put in a page, maybe the application.cfm that would show the user a message instead of the actual page?

  I had a site www.abc.com that I closed, but I must leave the pages on the server.

  I want it so that when a user enters the domain www.abc.com that they receive a message that the site is closed instead of the actual page.

  I want the user to get the message if they go to the homepage of www.abc.com or if they go to any page of the site.

  For example, www.abc.com/folder/index.cfm.

  Any suggestions?

  In Application.cfm, upstairs:

  This site is closed.

• How to listen to a user entering a room

  How do you listen for when a user enters a room? In the following code, enterUser() is not called if no user is in the room already, but called if a user already exists in the room.

  <? XML version = "1.0" encoding = "utf-8"? >
  < mx:Application
  ' xmlns:mx = ' http://www.Adobe.com/2006/MXML "
  xmlns:RTC = "AfcsNameSpace".
  layout = "absolute".
  creationComplete = "init ()" >
  
  < mx:Script >
  <! [CDATA]
  Import mx.controls.Alert;
  import com.adobe.rtc.events.UserEvent;
  
  protected function init (): void {}
  cSession.userManager.addEventListener (UserEvent.USER_CREATE, enterUser);
  }
  
  protected function enterUser(event:UserEvent):void {}
  Alert.Show ("user entered!");
  }
  []] >
  < / mx:Script >
  
  " < rtc:ConnectSessionContainer id ="cSession' roomURL = ' https://ConnectNow.Acrobat.com/MyAccount/myfirstroom "
  Width = "100%" height = "100%" >

  < / rtc:authenticator >
  < rtc:Roster width = "250" height = "250" / >
  < / rtc:ConnectSessionContainer >
  
  < / mx:Application >
  

  You do not get the event if you are one who came. If someone else enters, you will get the event. For your own, you can listen to UsetEvent.SYNCHRONIZATION_CHANGE to see that you came in and syncd upward.

• Question of simple layout, decrease of the TextField and TextArea in VBox

  Given:
  

          VBox root = new VBox(10);
          
          root.getChildren().addAll(new TextField(), new TextArea());
          
          Scene scene = new Scene(root, 300, 250);

  When I minimize the window of application vertically, textfield begins to shrink in the first place, while the text box remains its size, then when the TextField is a narrow strip, the text box begins to shrink.
  
  (1) is it planned?
  (2) it is design? If so, why?
  (3) how can I avoid, i.e. have the text box to shrink first, then the TextField?
  
  He thinks that the behavior in 3) makes more sense, since by its very nature, a text box can have different heights; a field of text on the other hand, I expect to have the height of one line of text, unless there is absolutely no space for him in its container. It is not supposed to have a textfield that is a fraction of the height of a line of text.
  
  I tried various combinations of minHeight and prefHeight, but without success.

  Hey,.

  (1) Yes, it's expected!
  (2) Yes, why... Well I don't know why the minimum height of a TextField is less than the size of pref.
  (3) this can be avoided by defining your own sizes (min size - pref - max size)

          VBox root = new VBox(10);
          root.setStyle("-fx-background-color: lightgray");
  
          TextField tf = new TextField();
          tf.setMinHeight(Control.USE_PREF_SIZE); //the minimum height = the preferred height
  
          TextArea ta = new TextArea();
          ta.setMinHeight(30);
          ta.setPrefHeight(50);
          ta.setMaxHeight(Double.MAX_VALUE); //maximum height, depends on the parent
  
          VBox.setVgrow(ta, Priority.ALWAYS); //use the maximum height available
  
          root.getChildren().addAll(tf, ta);
  
          Scene scene = new Scene(root, 300, 250);

• Pop-up window displayed when the url of the site is entered?

  Please can someone explain how to have a pop up appear as soon as you enter my website. So I need a little announcement to play when you land at the start of my site - so the video I see of "Lynda.com" is not what I am after forcing you to click on a link in the site. Mine needs to be there as soon as you land on my page with the option to close... Is this possible? If so, how would you please... Thank you in advance.

  You can expand the area of relaxation on the page and set the game slowing, so when the user loads the site and hover the mouse over the page, pop up appears.

  Also if you turn on autoplay, then loading the site itself the pop-up will be displayed on the screen, then you can configure on deployment of the shutter-click and place it behind any object of the page where users will not click.

  As there is no direct widget, this workaround works.

  But please feel free to add your own personalization, where you can insert a context menu using html or JavaScript.

  Thank you

• run when the user presses ENTER

  Hello

  I have a program that scans a serial number and gives power.

  RightNow, I scan the serial number and the hit on the laview toolbar.

  But, I would like to program it so that when the user scans a number it would automatically generate results, without me hitting run or an OK button at all times.

  I enclose my vi below.

  So, anyone has any tip for me on how I could go about this?

  Thank you very much in advance,

  Here is a version that uses polling.  The entrance was there properties so that it is not until that you press ENTER.

  The reference is in fact a local variable.

  Local variables and the voting clerk aren't often mouse, but for "just a text entry" app, it should work well.
