Capture of the error and saving a page in BB10 c ++

I try to use bb:system:screenshot as follows

request.setTarget("sys.pim.uib.email.previewer");

      // Set the action that the target app should execute
      request.setAction("bb.action.VIEW");

      // Set the MIME type of the data
      request.setMimeType("message/rfc822");

      // Specify the location of the data
      request.setUri(QUrl("pim:message/rfc822:" + QString::number(accountId) +":" + QString::number(messageId)));

      InvokeTargetReply *reply = invokeManager.invoke(request);

      sleep( 2 );

      //Screenshot
      bb::system::Screenshot screenshot;
      QString filename = screenshot.captureDisplay();
      if (filename.isEmpty()) {
          // Something went wrong
          bb::system::ScreenshotError::Type error = screenshot.error();
      }

      //Close Email
      invokeManager.closeChildCard();

The problem is the name of file is always empty and screenshot.error () always error values. Here's what the debugger said the line "something was wrong":

screenshot. Error() error: multiple errors reported. ------cannot run the MI command: - var - create - * screenshot.error () of the back-end debugger error message: could not find method bb::system:creenshot:error\ failed to create an object variable

Don't know what that means?

EDIT: I moved the variable definition out of the if statement screenshot and this error message:

Name : error
    Details:bb::system::ScreenshotError::PermissionDenied
    Default:bb::system::ScreenshotError::PermissionDenied
    Decimal:2
    Hex:0x2
    Binary:10
    Octal:02

Problem is, I certainly have the permissions set properly:

  
run_native
access_pimdomain_contacts
read_device_identifying_information
access_pimdomain_messages
bbm_connect
access_pimdomain_calendars
use_camera
use_camera_desktop
use_gamepad
access_internet
access_location_services
record_audio
read_personally_identifiable_information
access_pimdomain_notebooks
access_notify_settings_control
access_phone
_sys_inject_voice
read_phonecall_details
access_pimdomain_calllogs
control_phone
post_notification
_sys_use_consumer_push
run_when_backgrounded
_sys_run_headless
_sys_headless_nostop
access_shared
access_sms_mms
access_wifi_public

Documentation, I need "permissions: the application must have the permissions use_camera_desktop and access_shared to use this feature."

This has not yet been set internally.  Looks like you need a real device to test the screenshots with.  If you become a member of the BlackBerry partner program, you can access the loan and reduction devices.

    (2) if it works well before?

    (3) remember to make changes?

    It is sufficient to indicate the complete error message you receive.

    Note: FixIt would attempt to recover bad sectors on the hard disk, in the course of this process there are chances of DATA loss from that particular area.

  • AcroPDF in VB6 - text to search in the PDF and print this page.

    Okay, so I'm sure this question has been asked and answered 100 times, but for some reason that my Googling skills are seriously miss you today...

    I have a legacy application built in Visual Basic 6 that generates a special form letter PDF documents.  Each PDF contains all letters that were printed so far.  I really it work all rather decently, but something came earlier that put me on programming new obsession.  I want to activate the following features of my application:

    1. The user provides a text string that must be unique among all pages of all PDF (customer ID).
    2. The application then finds the PDF containing this text string that identifies which number of the page containing this text string.
    3. Finally, send only this page to the printer.

    I can now easily create, view, and print the PDF of my application.  While the creation of the document is made in a third of the reports system, display and printing functions are essentially managed using AcroPDF.dll.  Through the properties and methods available for AcroPDF object, I see that I can tell it to print only the specified pages, which gives me the last part of my needs, and I have the part of the user input down pat.  I'm just totally puzzled to find a solution to the 'step 2 '.

    Suggestions, ideas or comments would be greatly appreciated.  I'm a little tired of banging my head against a wall.  Thank you for your time.

    If you are only using Adobe Reader, then this feature is available.

    If you have Adobe Acrobat, then you have a few options.

  • How do the error of debugging JSP page/Javascript on the Blackberry browser on Simulator

    Hi, expert,

    at present, we are porting a web app (html5) from Iphone to Blackberry. It is written in JSP/javascript ajax in the backend. It is usually work the browser Blackberry 6.0 on a simulator. However, one of the page could be made, it shows just a blank page.

    I've seen an error like this onscreen Simulator MDS - CS:

    <2011-09-05 11:57:37.822="" edt="">: [1172] :::
    d receipt for non-existent packages! 904265821 >

    G = invalid, DEVICEPIN:CONNECTIONID = 2100000 a: 1770114602, SEQUENCE = 1, information
    tion = packet received for a connection timed out >

    However, I have seen the error on other pages when they are displayed correctly. Not sure why we continue to see this error.

    So, it could be a javascript error as well. Not sure at this stage. The page is written as a JSP page with javascript/ajax inside, which is the same as other pages that work. Very weird.

    No idea how I could debug to this case?

    Starting from the 7.0 you can use the web Inspector and in 5.0 you can debug using our tools, but in 6.0 you're stuck with more traditional methods such as the suggestion of chicoxmlof try/catch or alert statements

    Go-> Oracle Applications-> the execution Options for project properties and remove the OADeveloperMode of the selected list. This will stop showing the dev mode warnings when the page is run from Jdev. Note that these warnings should not be ignored, because they might indicate a leak in your code that might break at a later stage, so take note of these warnings and fix them if possible.

    First thing I would do, is try to turn the machine off and then remove the network cable from the machine.  Once extracted, try to turn the machine on and see if the error goes away. If so, there are probably a print job corrupted in the queue. Which you can remove by going in Printers and devices - the print driver for the HP - go to 'see what's printing' - right click and delete the tasks in there. If the drivers are not on a server or on your computer, you may wander and find the computer on which the print job is

  • Printing of documents that contain the letter and legal-size pages - Laserjet 600 M602

    We have a printer Laserjet 600 M602, that does not automatically select a tray to print every time someone tries to print a document that contains the letter so many pages of legal size.  The default printer for the Tray 1 (Manual power) and the user will have to walk over to the printer and the printer to select the correct tray.  I went in the printers settings via the web interface and I set the tray settings to the following: Tray 1 - any Type of Size/Any, bin 2 - letter/plain, plateau 3 - legal/Plain and it still does not print correctly.  Unfortunately for the printer settings, it was on that I'm comfortable doing.  I read the print driver may have changed, but we use the driver included with the disc and I guess that it would be sufficient that this driver.  Does anyone know of some setting that I might be able to change the printer or if it is indeed a print driver problem?  Any comments would be appreciated.

    Thank you

    I was able to receive help this morning from HP support.  He turns out, there were two things that I needed to change.  The first is that when printing from a pdf file, there is an option in the print area for "Choose paper according to the size of PDF page source" and the second thing, it was with the printer printing preferences.  In the printing preferences, under the "Printing shortcuts" tab, the paper Type has been set to Prepunched.  We changed this Unspecified.  After making these two changes, the user is able to print correctly in the printer.
