• [Explanation necessary] Clears the listview data and fill it again with new data

  Hello

  I correctly filled a listview in c ++, data analysed and does interesting things with it. However, I am drunk stumbling, unable to find a way delete and repopulate my display of the list...

  Question 1:

   

  1. How can after I insert data in the list view, I clear the list data and run again the same method (init) who populated the list view with the data in the first place?

  Here are the docs that I referenced and I don't understand how to implement the methods in my code.

  Question 2:

  How reference to the ListView object with the name "listView" in different parts of the MyApp.cpp file? Is there anything else I should add to the header file to make the accessible listView?

  Question 3:

  What happens when you call the clear() method? How the data model is affected? How the user interface is affected? What happens in memory?

  Question 4:

  How do you verify that the data in the list has been deleted so that you can go ahead and fills again with new data? What is the cheque that I perform?

  I would also like to know how you manage multiple views of lists and data sources in your applications. Best practices or ideas?

  Thank you
  

  I was able to clear the listview with the following code, if anyone is interested.

  listView.dataModel = null
  

  The dataModel must be set to "null".

• Error blackBerry software - synchronization failed, impossible to deal with organizing data

  I had a Q10 Blackberry last week.  I downloaded and installed the PC of Blackberry link 1.2.2.13 version.  Two-way sync USB worked fine.  Now, all of a sudden, I get the error message "synchronization failed, impossible to deal with organizing data."   I tried to reset the synchronization options, but not joy.  Also tried to uninstall and reinstall the software Link 1.2.2.13, once again no joy.  Any suggestions?

  UPDATE: I spent 4 hours on the phone and the remote session with the help of Blackberry last night.  After doing some troubleshooting to isolate the problem, determined that something on the device caused the problem of Outlook synchronization. One thing I've learned, it's that it can take a long time to synchronize and even though the progress of the screen may appear frozen, let it go until the end - sometimes it took 20-25 minutes, but eventually completed. Here's the process we went through - I would recommend appellant help BB and work with them to make sure you have not accidentally delete Outlook contacts and calendar of important information of your PC or BB device!.

  (1) we tried an uninstall/reinstall the PC Link BB software and that did not fix the problem.

  (2) to isolate the problem of synchronization.  We first did a synchronization of 2 channels 'contacts' and 'calendar' and who was a failure.  Then did a synchronization of only 2 channels 'contacts' and managed.  Then did a synchronization of only 2-way 'calendar' and that was a failure - so the problem was linked to calendar data and something on the device has been the cause of the problem or corrupted.

  (3) link BB allowing us to make a backup complete unit.

  4) then decided to do a 'Wipe security' on the device of BB Q10 to erase all the data and settings and return to a clean boot device configuration.  I was nervous about it - make double sure that Outlook all contacts and calendar data on the device and the PC are completely backed up in case something bad happens.  Nothing serious happened, but I was gald, we made the backup!

  (5) has the 'Security Wipe' feature (on the device, the settings > Security and privacy > wipe security) and phone rebooted without problems (takes a while to do).
  

  (6) then used link BB to do a sync test 1 channel 'contacts and calendar' from PC to device.  It worked without problem.

  (7) we then used BB link do a "restore" full backup of device, as we did in step 3 above.  It takes a while to make and was a success.

  (8) once the restoration of the aircraft was complete, BB link configured to perform a synchronization of 2 channels of the two 'contacts' and 'calendar '.  Does the synchronization and was a success.  Did a test by adding the new entry of the calendar on PC and did another 2-way sync - all worked very well.  Seems that the problem has been corrected, but will follow in the coming days.

  Lessons learned:

  (1) If you have a lot of Outlook contacts and calendar entries, the synchronization may take a long time.  Be patient and let it run - even if it seems stuck, etc!

  (2) save all Outlook data on the device and the PC to make sure that you have a backup something bad happened during troubleshooting.  We had not something bad happens, but I was gald we made a backup anyway.

  (2) call BB help - support person, I worked with was fabulous, even if it took some time to work through a patch.

   

• Problem with Capture Date & time change

  I just became aware of a problem with the Date of Capture use to is very strange. Initially, a brief explanation of the import workflow I'm used with jpeg image 6 iPhone since Lightroom Mobile was presented. The images appear in the section of times iPhone app Photo, and from there I transfer to a collection in Lightroom Mobile. Once the collection syncs to Lightroom on my Mac (running latest El Capitan), they sort by capture time and I make choices and rename images. I have a naming preset that adds automatically the date to all the images. Recently, I noticed that some of these images, but not all, have been appointed with the wrong date. I had traveled without my computer - only my iPad, and it was a month before the images have been synced on my Mac it was very obvious that the dates were incorrect. The problem may have expressed earlier, but if the date was off by a day or two he would not have been as sensitive.

  The problem occurs when I take pictures with the app in time of MomentLens company. I use the application because it is designed to work with instant attachment lenses and the case of the Moment (which makes no difference in time to capture problem).

  
  

  Once that the images are added to LR Mobile news for images show good capture date and time. That's when they images sync for LR (latest version) that the problem occurs. And this is not a problem of LR Mobile, such as changes of date and hour occur if images of the iPad are added to LR without using mobile LR (from the iPad to Mac with AirDrop). Looking at the EXIF metadata Panel in LR, images taken with the iPhone camera app show three dates: Date time Original Date time digitized and Date time - all the which three are the same. Show only pictures taken with the application of the time Date time, but it's the same as in the iPhone Photo app and in LR Mobile capture time. However, when I show info on imagine in Lightroom, the time that appears to capture the time is the time that the image has been synchronized (if it came at LR Mobile) or the time that the image has been added to the iPad over wifi. It is also the time that is added to the preselection of naming. Note that if I send a picture directly from the iPhone to the Mac with AirDrop the date and time is correct.

  For the life of me, I can't understand this anomaly. I did thorough Imaging tests, and it happens only with the application of the time - other camera apps do not exhibit this problem. Interestingly, LR recognizes both the time Soft, which is reported under EXIF on the range of software and the lenses of the Moment when it is used with the iPhone the Moment case.

  If anyone has any ideas I'd be pleased to entrance. Thank you

• AS the operator does not work with the DATE

  Hello
  I have a simple select statement and in the WHERE clause if I use AS with a date field it doesn't but it works with a string field. For example:

  --does not work. does not bring any rows
  Select * From MyTab
  Where  time_period Like '%';

  --works and brings ALL data
  Select * From MyTab
  Where  level_code Like '%';

  Where time_period is of data type DATE and VARCHAR2 level_code.

  Hello

  That's how AS is supposed to work.

  x LIKE y
  

  won't be TRUE if x is ZERO, no matter what.

  If you want an expression which returns TRUE when x is NULL and y '%', then use NVL to map NULL to an appropriate value.
  For example:

  Select  *
  From      Mytab
  Where       NVL ( TO_CHAR ( time_period
                        , 'MM/DD/YYYY HH:MI:SS AM'
                  )
           , ' '     -- One space
           ) Like '%';
  

  TO_CHAR to explicitly create a string based on a DATE, in the format that you want. Do not rely on implicit conversions.

• Consume a web service from ASP which responds with complex data types...

  Here's my problem - I'm trying to consume a web service from a provider that uses complex data types.

  The starting of the WSDL part looks like this (I have not included all) - named have been changed to protect the innocent:

  " < wsdl:definitions targetNamespace = ' http://domain_name ">
  WSDL: < types >
  " < s:schema elementFormDefault ="qualified"targetNamespace =" http://domain_name ">
  < s:element name = "Authentication" >

  < s:element minOccurs = "0" maxOccurs = "1" name = "Token" / >

  Since it is a return, with a sequence of complexType, I expect an array or a structure returned, but instead I just get the value of "AuthOK" and no way to get something else.

  Here are the ways I tried to call it:

  < cfscript >

  WS = createObject ("WebService", "https://WSDL_URL");

  WS_ret = WS. Authentication (name of user = "username", password = "password", token = "");

  < / cfscript >

  < cfdump var = "" #WS_ret # "/ >"

  < cfinvoke webservice = "WSDL_URL" method = "Authentication" returnVariable = "WS_ret" >

  < name cfinvokeargument = "SecurityToken" value = "" / > "

  < / cfinvoke >

• problems with the date picker

  I found some problems with the date picker to make my first presentation of object BPM.
  
  I created a group with a datetimestamp it contains. When I click on it in run mode, it will bring a new tab in the browser. This behavior is different from that of a date picker outside a group where there just a small javascript popup.
  
  Anyway around this problem?
  
  Also, would be nice if could be set by default to the current date. is there a way to who?
  
  For the component "time" it seems impossible to define the default value - at least on the tab object structure.
  
  Thank you

  Try to set the property "DHTML" to control date Yes. This option is under the Properties tab-> the calendar section. This will force it to use the popup javascript on screen instead of opening a new browser window/tab.

  To set a default value for a date/time, you can simply set the value in the constructor of the BPM object in which the property is located.

• Working with complex data types in web services...

  Hi all
  I have created a Web service and created an interface for this in the ADF. Now that my web service returns a complex data type, I followed the steps in this article "http://www.oracle.com/technology/products/jdev/howtos/1013/wsadf/adfcomplexwstypes.html" and it works very well, my results are also displayed. But the only problem is that I get a warning "Houston-25009: cannot create an object of type: java.util.calendar value: 2008-09 - 23 T 23: 51:30.000 + 05:30 ' and if I can replace all the java.util.Date oracle.jbo.domain.Date then I get a warning" Houston-25009: failed to create an object of type: oracle.jbo.domain.Date with the value: 2008-09 - 23 T 23: 51:30.000 + 05:30. Now I am unable to understand this, but I think it's a problem of data type mapping, but do not know how to remedy this.
  
  Everyone knows the wayout?

  Hi Lokesh,
  I have been troubled by the same question in the past. The problem is that the entrants is a format for dateTime xml adf trying to analyze the underlying java object. Java.util.Calendar, java.util.Date, or oracle.jbo.domain.Date to get a date in adf when scanning automatically your incoming xml file. See this thread on the forum for more information jdeveloper Re: how to deal with xsd: DateTime to webservice in ADF? The answer that gives Frank Nimphius is correct but I used option 1 option 2 should also work.

• Cannot create a new startup with my data disc

  Hi guys, here's the problem: when I try to create a new startup with my data disc, I can't boot from this drive.

  The startup progress bar takes forever and then I see a white circle with a line through it. ("Prohibited" / "Ghostbusters" sign.)

  In verbose mode, it hangs on "break pci: SDXC ' for a while, then it clears the screen and watch the Circle + line with 'still waiting on the root device' at the bottom left.

  I can't boot into single user mode. Quite simply, there is the same thing as verbose mode. Even in safe mode. So I have few options for debugging. I did a SMC reset, no change. Is there anything else I should try?

  Additional information:

  -I'm trying to start off a new SSD that I bought, currently in a USB 3.0 enclosure external. I know that all is well with the speaker because I started off of him several times in the past. I know that all is well with the reader, because I tried to do the same process with another drive and it doesn't work the same way.

  -J' cloned my current boot drive to the new drive with SuperDuper!, Carbon Copy Cloner and I also did a clean install of El Capitan using recovery mode. The new facility has worked well until I migrated my old data.

  - So there must be something in my data which are striated throughout this process. I don't know what it is maybe or how to track him down.

  Any thoughts are appreciated!

  Have you tried the PRAM reset? Restart while pressing control + command + P + R until you hear the boot chime at least twice.
