• Two monitors with x 200 and docking station

  Hello

  Is it possible to use two monitors with my x 200? I use a docking station that has 1 VGA out. When I plug a second monitor into the VGA output on the laptop, the screen adjusts a car but remains empty.

  Any help appreciated

  Concerning

  Andrew.

  There is also a displayport on the ban, so you can use a dvi DisplayPort converter / for the second monitor.

• Problem with background Images and scrolling

  I had to face for a while to get background pictures are working properly. Here's what I do:

  VFM VerticalFieldManager = new VerticalFieldManager();

  Card of bitmap = Bitmap.getBitmapResource ("MyImage.jpg");

  Background bg = BackgroundFactory.createBitmapBackground (map);

  vfm.setBackground (bg);

  This works, but has entrapment. First of all, he painted only as much as you have fields too much room, so I have to add empty fields just to occupy vertical space. However, on a page with something like a listField, where the height is variable, this can lead to what the background image are starting to repeat and to allow scrolling.

  What I want to do is to block all the scrolling and have the training exactly fill the screen with no scrolling or white empty places.

  I'll just on this wrong? Would really love to help...

  Hello

  Hope this will help you.

  class LoginScreen extends MainScreen {    //Manager        private VerticalFieldManager _manager;
  
      LoginScreen() {        //Set Background image            _manager = (VerticalFieldManager)getMainManager();            Background bg = BackgroundFactory.createBitmapBackground(Bitmap.getBitmapResource("back.png"));            _manager.setBackground(bg);
  
     }}
  

  Add this manageron your screen don't add any component in this handler.

  You add fields in the Manager of the other, and adds that the Manager on the screen.

  Let me know if this solves your problem or not.

• How to set up two monitors with screen LCD and HDTV on computer that is running Windows 7

  Issues of identity and position monitor

  I use a LCD and an HD TV on my computer. I have HDTV mounted to my left on the wall in my room and the LCD is on my desk in front of me. I have my monitor set as my main screen and HDTV as secondary. Windows identifies the HDTV as monitor 1 and my screen LCD 2. After starting the computer they work very well as they should. My problem is during the boot process. When the computer starts, it displays only the boot screen/POST on monitor 1 (HDTV) but not my main screen #2 (LCD). This is a problem when I don't have my HDTV now, I don't see the MESSAGE options. I don't want to always have my HDTV and crane my neck every time I need to change the BIOS settings or use the MESSAGE options. Is there any solution for this?

  Hi Darth Polizei,

  I hope that's not redundant but did you try to set your monitor 19 "as the main display?

  1. In the screen resolution window, you click the icon of the monitor that represents the secondary monitor.
  2. You click to select the "Make my main screen" check box, and then click OK.
  3. You log out of the computer.
  4. You log on to the computer.

  Please let us know.

• TreeView with icons displayed incorrectly after expansion (8 JavaFX)

  I have a TreeView with classes CellFactory and TreeCell custom, which has been implemented in JavaFX 2.2 and works perfectly. However, after I upgraded to 8 JavaFX. This tree is completely messed up. If I develop a nodes, there will be duplicate tree nodes in the tree. Here is a simplified version of the source code. If not use a method setGraphic() in class TreeCell, it works fine.

  package test;
  
  
  import javafx.application.Application;
  import javafx.scene.Scene;
  import javafx.scene.control.TreeCell;
  import javafx.scene.control.TreeItem;
  import javafx.scene.control.TreeView;
  import javafx.scene.image.Image;
  import javafx.scene.image.ImageView;
  import javafx.scene.layout.BorderPane;
  import javafx.stage.Stage;
  import javafx.util.Callback;
  
  
  public class TreeViewTest extends Application {
      private static final Image image = new Image(TreeViewTest.class.getResourceAsStream("icon_datasource.png"));
      
      public TreeViewTest() {
      }
  
  
      @Override
      public void start(Stage primaryStage) {
          BorderPane rootPane = new BorderPane();
  
  
          TreeItem<String> root = new TreeItem<String>("Root");
          
          for (int i = 0; i < 5; i++) {
              TreeItem<String> ds = new TreeItem<String>("Datasource " + i);
              
              for (int t = 0; t < 5; t++) {
          TreeItem<String> tb = new TreeItem<String>("Table " + t);
          ds.getChildren().add(tb);
              }
              
              root.getChildren().add(ds);
          }
          
          TreeView<String> tree = new TreeView<String>();
          tree.setCellFactory(new Callback<TreeView<String>, TreeCell<String>>() {
       
       public TreeCell<String> call(TreeView<String> param) {
    return new TreeCell<String>() {
       @Override
       protected void updateItem(String item, boolean empty) {
           super.updateItem(item, empty);
           
           if (!empty) {
               ImageView imageView = new ImageView(image);
               setText(item);
               setGraphic(imageView);
           }
       }
    };
       }
    });
          tree.setRoot(root);
          tree.setShowRoot(false);
          
          rootPane.setLeft(tree);
          
          Scene scene = new Scene(rootPane, 1024, 800);
  
  
          primaryStage.setTitle("Test");
          primaryStage.setScene(scene);
          primaryStage.show();
      }
      
      public static void main(String[] args) {
          launch(args);
      }
  }
  

  In general, cells are reused as items in TreeView (and some make, and ListViews) as soon as they become visible and invisible. It is perfectly possible for a cell to have an element that is not empty and then it change to empty, as the cell is reused for an empty cell.

  If you have a bug in your code: you need

  tree.setCellFactory(new Callback, TreeCell>() {
  
              public TreeCell call(TreeView param) {
                  return new TreeCell() {
                      @Override
                      protected void updateItem(String item, boolean empty) {
                          super.updateItem(item, empty);
  
                          if (!empty) {
                              ImageView imageView = new ImageView(image);
                              setText(item);
                              setGraphic(imageView);
                          } else {
                              setText(null);
                              setGraphic(null);
                          }
                      }
                  };
              }
          });
  

  You lucky in JavaFX2.2 that the re-use of cell does not seem to affect your bug. improving the effectiveness of the re-use of the cell in JavaFX 8 has exposed the problem.

  Furthermore, it is generally a bit pointless to re - create the nodes each time than updateItem (...) is called (frequently), rather than create them once when the cell is created (much less often). So consider

  tree.setCellFactory(new Callback, TreeCell>() {
  
              public TreeCell call(TreeView param) {
                  return new TreeCell() {
                      private ImageView imageView = new ImageView(image);
                      @Override
                      protected void updateItem(String item, boolean empty) {
                          super.updateItem(item, empty);
  
                          if (!empty) {
                              setText(item);
                              setGraphic(imageView);
                          } else {
                              setText(null);
                              setGraphic(null);
                          }
                      }
                  };
              }
          });

• Can I plug two Airport Express units with ethernet cord and have a third Airport Express Terminal receive airplay music wirelesslly? In other words, can I combine a Wi - Fi network and roaming?

  I have an undesirable on the 1st floor, connected to the cable modem Ethernet event. I want to connect that AE to an another AE on 2nd floor with ethernet cable AND have a 3rd AE on the 1st floor to receive music through AirPlay wireless. I thought that linking the two first AEs with ethernet would improve the performance of web site on my iMac desktop, which is on the 2nd floor and connects to the 2nd floor AE via wifi. The EI the first two are newer model (MC414LL/A); the 3rd AE is old model (MB321LL/A) and is connected to a stereo Bose with a mini-jack to RCA cable double cord. I tried to set up this network using AirPort Utility, but have had no success. I don't know if it is possible to do what I want to do; and if this is the case, I don't know how to set the various parameters for each AE using AirPort Utility. I've temporarily implemented a purely wireless network; Do not connect DO NOT the two AEs with ethernet and everything works. I would enjoy my plan as above, or if I hold with purely network wireless. Any help would be greatly appreciated.

  Using ethernet network roaming between the two floors is a much better idea than anything wireless.

  The installation should be automagical if you start with the two AE plugged in by ethernet.

  It must be configured in standard roaming with identical names wireless.

  If you have any questions... Please, just after the airport utility screenshots of the configuration... but

  An express train is probably the router? You must confirm this.

  The second express is so configured in bridge... It's on the network tab, disable the bridge mode.

  

  Without thread is set to create a wireless network and simply use the same name and the same password as the other Express.

  As it should be automagical when you WAN on the second AE plugged into the LAN on the first AE.

  Wireless and then extend to will also be installed enough well automatically even if sometimes it works better in a client that extend wireless mode.

  See the Client mode.

• T410 AiO customer CAPS, NUM, and scroll keyboard stop does not work with PCoIP view desktop computers

  We have problems with our t410 AiO customers, where the CAPS, NUM and scroll stop lights on the keyboard do not work with view PCoIP desktop computers.

  I found the below information and a work around:
  If you use the Protocol PCoIP to display on a client system Ubuntu 10.04, the CAPS Lock, NUM Lock, and Scroll Lock lights on your keyboard do not work with desktop view. Although the lights do not work, the keys themselves work.
  Solution: Set the following configuration in a configuration file, such as/etc/vmware/config:
  mks.keyboard.useXkbSetNamedIndicator = 'TRUE '.

  The problem is this difficulty is already in place via the latest version of the HP, Z6A440, software that is installed within our Organization.

  What I discovered, is that the model that we initially bought for the test doesn't have this problem.  However, the models that we ordered since that time, DO have the problem and the solution above does not work as expected.

  The model originally ordered for test is still a customer of IOA t410... but there are 4 "under models' for customers of IOA t410... that we have to test is a H2W20AA, while those we receive and distribution are the H2W21AA model.

  No idea why, when connected to the desktop from view, that models of H2W21AA have this problem?

  H2W20AA is with Teradici PCoIP optimized, which can support PCoIP better, but H2W21AA is not with Teradici. That's the difference.

  However, the issue that you are experiencing does not matter in fact, we have not heard of this problem before. I would suggest that you do the following to see if there is no change:

  1. Go to download the latest VMware View 2.3.4 for t410, follow the instructions to install.
  2. If suggestion 1 does not work for you, try to connect to another VM group or set up a new machine virtual clean
  3. Call HP service center to save your problem for further investigation if the suggestion above did not work

• With W - XP and a utility 6540dt, why it prints black (bakkup) with two LDTC wet ink?

  Someone out there:

  I'm under Windows XP and using a HP Deskjet 6540dt printer.  I removed two LDTC (ink cartridges) which indicated down and replace them with two new HP Inkjet LDTC and the printer indicates it will only print black ctg in backup modeusing.   This got me puzzzled.   I deleted the drivers and reinstalled from a CD disc (part No. C8963-10001) HP   after reinstall the drivers, the printer still prints with the onlyblack print cartridge.  I was super confused.

  I am running AVG free edition , and Microsoft Security Essentials and have even unintalled them then turing the driver for the Modem from Verizon to reintall the HP Deskjet 6500 series and still no luck I thought that the firewall can interfere with the installation.  He does not appear.

  What do you think is the problem?.    I have the installation disc at home MS W - XP original (not a recovery disk) and have all the dates of arrival and Service Pack (SP-3).

  I'll have to take the computer and printer to a repair (specialist) {no BestBuy or Geeks or Office Depot} man or can I fix it myself. ??   If I can fix it myself, you please give me instructions step by step IE: A: cela;  B: do;    etc.

  The specialist repairer should have renovated th ? printer

• Problem with onFocus and scrolling

  I have a table built with a VerticalFieldManager and have implemented the standard shortcut scrolling. There was a problem where the onFocus event has not fired on my table cells when 'b', 't', 'space' shortcut keys have been used (though even the focus change). I had to add the fireFocusHack() to fix. I wonder if it isn't something I am doing wrong or is this a bug of BB OS? It works without the hack in the simulator of 8330 I use JDE 4.5. The notch is necessary on a Bold 9700 running 5.0 and a 4.6 running curve.

      public boolean keyChar( char c, int status, int time ) {
  
          if (tableCellHasFocus()) {            Field f;            switch( c ) {                case Characters.SPACE:                    if ((status & KeypadListener.STATUS_SHIFT) == 0) {                        scroll( Manager.DOWNWARD );                    } else {                        scroll( Manager.UPWARD );                    }                    fireFocusHack();                    return true;                case 't':                    scroll( Manager.TOPMOST );                    fireFocusHack();                    return true;                case 'b':                    scroll( Manager.BOTTOMMOST );                    fireFocusHack();                    return true;            }        }
  
          return super.keyChar(c, status, time);    }
  
      private void fireFocusHack() {        Field f = table.getFieldWithFocus();        if(f instanceof MessageCell) {            MessageCell tc = (MessageCell)table.getFieldWithFocus();            tc.setFocusHack();        }    }
  
  public class MessageCell {
  
     ....
  
      public void setFocusHack() {        onFocus(0);    }...}
  

  I found this one. Table cells were VerticalFieldManagers which contained a focusable RichTextField. It was my onFocus() and onUnfocus() methods were on optimizing resources aren't the RichTextField. The funny thing is that it has worked well for manual/trackball scrolling.

• Why do two files with half of the songs on the album in one and the other half to the same album

  When I download an album place it in my folder of music, and then to the Media Player update the album information I have two albums of the same name in media player with four titles in and the other with seven titles and all tracks are from the same album...

  Hello

  You can re-create the database of Windows Media Player and see if that fixes the problem.

  To resolve this problem, delete the Windows Media Player database. To do this, follow these steps:
   
  a: Exit Windows Media Player.

  
  b:  Click Start, type %LOCALAPPDATA%\Microsoft\Media Playerand then click on OK.
  
  c: select all the files in the folder and then click on Delete on the file menu.

  Note You don't have to remove the folders that are in this folder.

  d:  Restart Windows Media Player.

  Note Windows Media Player automatically rebuilds the database.

  
  If this does not resolve the problem, disable the Windows Media Player database cache files. To do this, follow these steps:
   
  a: the release of Windows Media Player.
  
  b: click Start, type %LOCALAPPDATA%\Microsoftand then click OK.
  
  c : select the Media Player folder and then click delete on the file menu.
  
  d: Restart Windows Media Player.

  Note Windows Media Player automatically rebuilds the database.
