QNetworkAccessManager finished signal never happens

• finished() signal for invoke() on phone app)

  I use bb::system:InvokeManager to start a call using action 'bb.action.DIAL '.

  response of bb::system:InvokeTargetReply * const = invokeMgr.invoke (invokeRequest);

  Invoke() will return an InvokeTargetReply. This response will signal finished(). I use

  Boolean result = QObject::connect (response, SIGNAL (finished (()), this, SLOT (onInvokeResult ()));

  to connect the signal with the slot. However, my CRACK onInvokeResult() is never called. Why is this?

  (1) something wrong with my application?

  (2) signal/slot mechanism only works inside your own application. If this approach can be used when calling invoke() to an external application. Signal/slot isn't an IPC mechanism.

  Documentation says errorType and errorCode is valid after the finished() signal.

  BB::System:InvokeTargetReply * response = qobject_cast(sender());
  BB::System:InvokeReplyError:type errorType = response-> error();
  int errorCode = response-> errorCode();

  If the signal/slot mechanism cannot be used internally within your own application, how can you know if the invoke() on an external application would be successful?

  I wasn't looking to extract the right aways errorType and errorCode after calling invoke()... maybe that can already tell me the result?

  Thanks for sharing this code. My code is almost the same. And I solved the problem. My code now looks like this:

  BB::System:InvokeManager invokeMgr;
  response of BB::System:InvokeTargetReply * = invokeMgr.invoke (invokeRequest);
  If (answer)
  {
  Set the parent for this 'response' otherwise 'response' will be deleted at the end of this function.
  response-> setParent (this);
  Boolean result = QObject::connect (response, SIGNAL (finished (()), this, SLOT (onInvokeResult ()));
  ...

  void controller:nInvokeResult()
  {
  Get the response from the sender object
  BB::System:InvokeTargetReply * response = qobject_cast(sender());
  BB::System:InvokeReplyError:type errorType = response-> error();
  int errorCode = response-> errorCode();

  response-> deleteLater();
  }

  It turns out that it is absolutely essential to add a parent to the response using the line "answer-> setParent (this);" in order to receive the signal finished(). If this line is commented out, then the slot is more will be called.

  You may not use a local variable for the answer, but a member of the class. That also seems to work.

  Thanks for the help!

• InvokeTargetReply finished() signal not shooting?

  I have a problem like that in the original post in this thread:

  http://supportforums.BlackBerry.com/T5/native-development/invokation-framework-slot-for-signal-Finis...

  The poster of thread apparently solved their problem for their use case by invoking a card instead of an application, but this solution is not suitable for my use case - I simply invoke a basic application, by using a reusable code taken right out of BlackBerry tutorials, and apparently, so the launch of base app, finished() signal is not emitted.  This seems so basic that I expect others have run across it, and there is a subtle touch that is not sufficiently covered in the tutorials.

  Code:

  void ApplicationUI::launchCoreApp() {
  
      qDebug() << "The launchCoreApp() method was called";
  
      bb::system::InvokeManager invokemanager;
      bb::system::InvokeRequest request;
  
      request.setAction("bb.action.OPEN");
      request.setTarget("sys.browser");
      request.setUri("http://www.blackberry.com");
  
      bb::system::InvokeTargetReply *reply = invokemanager.invoke(request);
  
      if(reply) {
          if(reply->isFinished()) {
              qDebug() << "In launchCoreApp(), reply finished before we could connect signal to handler slot";
          } else {
              qDebug() << "In launchCoreApp(), connecting reply finished signal to handler slot";
              bool ok = connect(reply, SIGNAL(finished()), this, SLOT(onInvokeTargetFinished()));
              Q_ASSERT(ok);
          }
  
      }
  
  }
  
  void ApplicationUI::onInvokeTargetFinished() {
      qDebug() << "The onInvokeTargetFinished() slot was reached";
  }
  

  Note that this is just a test code and I didn't intend to instantiate a new InvokeManager on each call to the launchCoreApp() function - I just need to see how things work.

  So, when I run the above, launches the browser and goes to the provided URI, my debug console told me that the value of reply-> isFinished() is false, so my code takes the branch to connect the finished() signal to the onInvokeTargetFinished() slot.

  However, the slot is apparently never called, not the browser launch and not when I close the browser.

  It's reusable code light directly from the tutorials and docs, but it doesn't seem to work as announced.

  When subtle I'm missing?

  Where in the lifecycle of the invocation request response is the finished() signal is supposed to be issued?  The reference docs are very clear on this - they just say it is issued when the response message is "received", whatever that means (I understand that it is a future model, I'm not clear which is received in the life cycle integer invocation response).

  I am compiling against level API 10.2 BTW.

  I work, the only thing needed is to define the parent for the response, otherwise it will be deleted at the end of the function where it is created.

      bb::system::InvokeTargetReply *reply = invokemanager.invoke(request);
      reply->setParent(this);
  

  The parent is responsible to remove the answer, so be sure to remove it in your home.

  void ApplicationUI::onInvokeTargetFinished() {
      qDebug() << "The onInvokeTargetFinished() slot was reached";
      bb::system::InvokeTargetReply *reply = qobject_cast(sender());
      reply->deleteLater();
  }

  Firefox for android will get firefox Hello and when? Or will never happen because telefonica is not interested to have in firefox for android?
  Hello, Firefox is the right thing and it would be much larger if it is available on android for direct use from phone to phone.

  I don't have an ETA for you, but it is spoken, here is a list of bugs to integrate the UX, etc.:

• Downloaded the new 31.1.1 and now, the program adds quotes in my email addresses and gets rejected by my server. Never happened before. Please fix this!

  It's never happened before. Ever since I downloaded the new version 31.1.1, Thunderbird adds automatically quotes in my email addresses in my address books, but only when I send an email in bulk for a lot of people. These quotes "" "show up on top of the same e-mail addresses in the"to"or"bcc"list of recipients, then on my server refuses to send. Please fix this. Sincerely, Doc

  your address entries have a space either before they address book so they get cited. check the entries in the address book for an attack or of trailing white space

• Downloaded just ver9 Firefox, now I can't record passwords, what, what's the problem with worm 9, this never happened with other versions.

  Just download Firefox VER 9, now I'm unable to save passwords, this never happened with an another Version of Firefox. I have tried everything I know to solve this problem, I ticked the boxes in the options, where it says to save passwords, don't know what else to do, may be using Solution Explorer.
  Thank you bob.

  Do you hear the names and passwords in the password manager or do you mean that you are connected is no longer on to (remember to) Web sites after the closing and restarting Firefox?
  
  There is a difference between remembering the name and the password in the password manager and a check box "remember me" on a web page.
  
  The latter usually involves the creation of a special "remember me" cookie that is stored on your computer and which is sent to the server.
  
  If that "remember me" cookie is deleted or is corrupted or is not send to the server, then the server remember that you and you must connect once again.

• Hi, windows 7 Disk Defragmenter problems daily schedule set for all discs, never happens, it sometimes takes weeks

  Hi, windows 7 Disk Defragmenter problems daily schedule set for all discs, never happens, it sometimes takes weeks. Have a disk busy on the farm that is used for the storage of video surveillance. When I realize the performance issues, I check and find tht 'daily' Setup for MS disk defragmentation is not in fact run every day. I am watching silent movies and waiting for a 500 GB drive to effectively defragment, pass it is on average 1 percent per minute (with any other IO goes on the disc and app collection closed).

  There must be (I hope) a flag I can put to Disk Defragmenter to be more aggressive in its analysis.

  It is Windows 7 64 bit running on AMD processors, disks are sATA plugged in, although there is also a matrix RAID PCI Promise, it's usually when I started Hello I/O on the Board of 2 TB or utilization of the 'C', I realize the lack of defragmentation. I recall, before the SP1 under WIN 7, he ran on a daily basis, in fact, rather than an API algorith "guess".

  System is in place 24 x 7 (I turn off the monitor at the time of sunset), there is no "powersaver" feature used on this particular device. I edited my original question because after many years of support, I realized, by asking the initial question, that I was not providing information that I would be asked a customer, if I was still doing this job.

  Kind regards

  Lorin Boyack

  Hello Lorin,

  There are several reasons why the built-in Defragmenter may not work correctly:

  Method 1: He is also a malware on the system. Solution: Run an anti-virus control and also a spyware check.

  I suggest you scan your computer with the Microsoft Security Scanner, which would help us to get rid of viruses, spyware and other malicious software.

  The Microsoft Security Scanner is a downloadable security tool for free which allows analysis at the application and helps remove viruses, spyware and other malware. It works with your current antivirus software.

  http://www.Microsoft.com/security/scanner/en-us/default.aspx

   

  Note: The Microsoft Safety Scanner ends 10 days after being downloaded. To restart a scan with the latest definitions of anti-malware, download and run the Microsoft Safety Scanner again.

  Important: During the scan of the hard drive if bad sectors are found, the scanner tries to repair this sector, all available on which data may be lost.

  Method 2: The disk is too full (you need at least 15% free space, sometimes 20%). Solution: Delete files unnecessary and programs until you have more than 20% free space.

  Delete files using disk cleanup

  http://Windows.Microsoft.com/en-us/Windows7/delete-files-using-disk-cleanup

  Method 3: The disc is damaged and must be repaired. Solution:

  a. open "Computer" and right-click on the drive that you want to disable frag.

  b. Select 'Properties' and click on 'tools '.

  c. Select "Check now" to check the drive for errors.

  d. Select the two options and click on 'start '.

  Check your hard drive for errors

  http://Windows.Microsoft.com/en-us/Windows7/check-your-hard-disk-for-errors

   

  Important: While running chkdsk (check disk) hard disk, if bad sectors are found on the hard drive when chkdsk attempts to repair this sector, the data available in this area may be lost, and it is not recoverable.

  (This can take time and can restart the PC so that it can do the check at boot time. Be patient and let it complete).

  Method 4: Disk Defragmenter may be corrupted, requiring a system restore to fix.

  System restore

  http://Windows.Microsoft.com/en-us/Windows7/products/features/system-restore

   

  NOTE: When you use system restore to restore the computer to a previous state, the programs and updates that you have installed are removed.

  Method 5: There are other programs that are running this interruption, the built-in Defragmenter. Solution:

  a. close all running programs.

  b. If you think there may be some programs that run in the background.

  c. press Ctrl + Alt + Delete and

  d. Select "start Task Manager".

  e. under the 'Applications' tab, you will find a list of all running applications - you can close these by selecting "end task."

  Hope this information helps. For any other corresponding Windows help, do not hesitate to contact us and we will be happy to help you.
