Display.screenshot cause ControlledAccessException

• Display.screenshot does not behave as expected

  Hello

  The Display.screenshot method doesn't seem to work as expected. When I call this method, I got the dialog box asking the user or not to allow a screen capture to take. If the user selects Hello but leaves theDo ask not agai box unchecked, the screenshot is not taken. If, however, select 'allow' and check the box "Do not ask again" the screenshot is taken. Maybe that's a problem with the dialog box?

  Here is my code below-
  try {}
  Display.screenshot (this.bitmap, 0,0, Display.getWidth (), Display.getHeight ());
  }
  /**
  * If the user does not have a screen capture taken just display the General image
  */
  {} catch (ControlledAccessException cae)
  This.Bitmap = Constants.BACKGROUND_IMAGE;
  }

  Depends on how you code.

  Personally I d code it as follows:

  (a) have an indicator of persistent screenshot with three States

  0 - does not define

  -1 can't screenshot

  1 is allowed to the screenshot.

  Check this box if you are about to make a screenshot.  In this case - 1 indicate to the user that they have disabled this function be selected permissions.  If it's 0 or + 1, check the permissions API to see if you are allowed to do.  If you are, then set the value to 1 and do.  If you're not, tell them that they need to enable and display the permissions API.  When that is saved, check again.  If they helped him, set the indicator 1 and continue.  If they don't have not enabled it, it the value - 1 and tell them that you can't capture screens because they were disabled.

  Not sure which covers all cases, but you get the idea.

  Ok?

• Upcoming context menu in the screenshot using Display.Screenshot

  Hi all

  I have a Menu item. When click on that I take screenshot, but I also get the context menu in the screenshot. I want only the screenshot to the screen behind the context menu.

  Pointers for this?

  Thanks in advance,

  Sandeep

  Thanks for you answers.

  I tried to have the timer also option to wait for a while before taking screenshot didn't work.

  Then I tried after option, it worked. I've added a call to repaint before taking a screenshot. Is this a good method to do?

  // Added this line before taking screenshot UiApplication.getUiApplication().repaint();
  Display.screenshot(bitmap,0,0,Display.getWidth(),Display.getHeight());
  

  I'll also explore the options mentioned by you.

  Thank you

• How close or minimize the menu box using Display.screenshot ()?

  Hello

  Did someone help out me in finding what way I can minimize or close the menu box while I take the screenshot of any screen?

  The problem is when I select the menu item Printscreen, the Display.Screenshot () method runs, and it takes the screenshot including the menu box that I opened for the selection of the menu-item (Printscreen).

  So, how to remove that box of Menu before you take the screenshot?

  Please answer

  Thank you.

• Display.screenshot (bitmap) returns white screen

  Hi all

  I develop an application that uses the camera (VideoControl and player).

  Here I am pasting my code

  String encoding = "encoding = video/3gpp & mode = standard;
  _player = Manager.createPlayer ("capture://video?" + coding);
  _player. Realize();

  _videoControl = (VideoControl) _player.getControl ("VideoControl");
  If (_videoControl! = null) {}
  Field videoField = _videoControl.initDisplayMode (Field) (VideoControl.USE_GUI_PRIMITIVE, "net.rim.device.api.ui.Field");
  Add (videoField);
  btnStart = new ButtonField ("Get Snap", ButtonField.CONSUME_CLICK |) ButtonField.FIELD_HCENTER);
  Add (btnStart);
  _videoControl.setVisible (true);
  btnStart.setChangeListener (this);
  _player. Start();
  }

  On the click event of a btnStart buutonField I call it

  public void fieldChanged (field field, int x) {}
  Bitmap bmp = null;
  VerticalFieldManager vfmMain = new VerticalFieldManager)
  VerticalFieldManager.VERTICAL_SCROLL | VerticalFieldManager.VERTICAL_SCROLLBAR);
  While (snapCounter< 20)="">
  BMP = new Bitmap (Display.getWidth (), Display.getHeight ());
  Display.screenshot (BMP);
  vfmMain.add (new BitmapField (bmp));
  BMP = null;
  snapCounter ++;
  Thread.Sleep (100);
  }
  }

  bitmap HE I includes the pictures seen in the camera too.

  But it works fine when I run the application for the first tiem after installing it in the appliance.  When I get out the request and re-launch it he gives screen but without the camera images.  I want the image with the images of the camera.

  Please, someone knows why it's happening. And is there a solution for this.

  Thank you

  For this best prectice is to use the playerListener and overrride method.

  ' Public Sub playerUpdate (player pl, event of the string, eventData object) {}
  try {}
  I have if (event.equals (PlayerListener.STOPPED)) {}
  close the player
  _player. DEALLOCATE();
  _player. Close();
  } else {if (event.equals (PlayerListener.CLOSED))
  write your meeting
  }
  }
  } catch (Exception ex) {}
  System.out.println ("playerUpdate Exception" + ex.toString ());
  }
  }

  This works well.

  Now whenever it gives the page... with video...

• Horizon view Agent 6.0.2 Windows 8.1 desktop - size setting display scale causes mouse which will be pasted in the top left corner

  Hello

  I am having some problems when I try to adjust the size to the scale option in the Virtual Office Windows 8.1 with view agent 6.0.2. When I try to change the scale via Control Panel -> display -> option to change the size of all the items ( view failover control settings is disabled by VMware KB: Settings tab is not available in the display panel of a Horizon view desktop locally when t...). After that, the mouse pointer gets suddenly blocked until the upper-left corner, and I'm unable to move the mouse pointer on this corner that the mouse pointer continues new jump in him. When I change the scale to the original (use the keyboard to change the setting), the behavior of mouse pointer returns to normal.

  Anyone else having this problem?

  Found the solution by adding a registry entry:

  Location: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Teradici\PCoIP\pcoip_admin_defaults

  Name: pcoip.disable_cursor_jumping

  Type: REG_DWORD

  Data: 1

  After that it is defined on the parent image and recomposed (or reboot if you want to set this on a persistent desktop computer), there is no more mouse pointer jumps after changing the scale of the fonts/AC.

  This was indeed listed in KB here — not exactly the problem listed in the KB, but it is quite similar:

• Satellite Pro A100-080: NVidia display driver's break in 3D games

  Hello

  I have some problems with the display driver since I bought the laptop 9 months ago. I tried to install each new driver published on the toshiba site but no driver is running stable on my system.

  The problem is that my laptop crashes with blue screen when playing 3d games and my windows vista tells me that it is the display driver causing accidents.

  I had the previous version of the driver installed several months ago and I think it's more stable than the current version. Unfortunately I lost the files for that one, but I prefer a functional driver for this laptop.

  If I use this code to capture a screenshot on an OS 6 Toch:

  Then it works perfectly in vertical mode, but when I turn the camera in landscape mode and take a screenshot, then it gives me an illegalargumentexception. don't someone here on this?

  You create a new Bitmap every time? The dimensions are set correctly for the bitmap when you turn? In addition, there should be a message to the Exception, what is?

• Convert Image screenshot of Bitmap file?

• Screenshot method

  Hi all

  I use the following code to capture screen:

  Bitmap image = new Bitmap( 64, 64 );                             Display.screenshot( image, 0, 0, 64, 64 );
  

  I then use:

  image.getType () which returns 197: ROWWISE_16BIT_COLOR

  But if I had to use

  Bitmap image = new Bitmap( 64, 64, Bitmap.ROWWISE_16BIT_COLOR );Display.screenshot( image, 0, 0, 64, 64 );
  

  He throws an IllegalArgumentException saying that is not supported

  Can someone explain this?

  Certainly if the created image is going to be a ROWWISE_16BIT_COLOR, then you can create a bitmap image in ROWWISE_16BIT_COLOR for the screenshot to use?

  According to the documents of the developer, the first parameter is the type where you should type and not in the last...

  Bitmap(int type, int width, int height)
  

  Given that the first parameter is 64, it shows that there is an illegal argument...

• Screenshot using touchscreen devices

  Hello friends,

  I and requirement to capture the screenshot of blackberry. I can do this using the class net.rim.device.api.system.Display as follows:

  Bitmap screenBitmap=new Bitmap(Display.getWidth(),Display.getHeight());
  Display.screenshot(screenBitmap);
  

  But in the case of devices with touchscreen when the on-screen keyboard is visible the code above only takes the screenshot of the screen above the on-screen keyboard and not to take the screen shot of the on-screen keyboard.

  So I ask your valuable comments on how I can get the screenshot of the full screen, including the on-screen keyboard when it is visible.

  Thanks and greetings

  Hello Michael, thank you very much, the code you posted has worked perfectly

  I've never looked on this method.

• Copy a screenshot in a Bitmap image does not work on a device

  I have developed a program that creates a Bitmap and copys a screenshot inside.

  This works on the 8820 Simulator, but not on firmware 8820 4.5.0.37.

  It throws the exception on the device. I think I need to know what kind of Bitmap must be created before you take the screenshot. There's a Constuctor Bitmap with a type parameter. Do I need to use it to create the correct Bitmap?

  Following is the screenshot:

  Bitmap TheBitMap = new Bitmap (Display.getWidth (), Display.getHeight ());
  Display.screenshot (theBitMap);

  Thank you Jürgen

  I rebooted the BlackBerry, deleted and reinstalled the application.

  Then the Exception disappears so the problem just magically disappeared.
