QFile created vs lastModified
I would get the two stamps of QFile:
created()
lastModified()
It seems that the BB10 always replace created()
file is stored in my sandbox/data
I test if the file exists, and then I do something like this:
QFile file(myPathToFile);
if (!file.open(QIODevice::ReadWrite)) {
return;
}
.....
file.write(*buffer);
file.flush();
file.close();
now created() changed
Because I'm replacing the contents of an existing file, I expected to have unchanged created() and lastModified() updated.
or I'm doing something wrong update the content of a QFile?

According to the docs, "if creation time or time of"last status change"are not available, returns identical lastModified().
https://developer.BlackBerry.com/native/reference/Cascades/QFileInfo.HTML#created
Looks like that's not available. Might be worth a feature in this case request.
so I'll create a feature request
I read the docs, but could not imagine that a modern OS like BB10 does not provide something basic like a timestamp of creation of file ;-)

Cannot create a .db file in the folder data
I use this code
const QString fileName = QString("rules.db"); QString dataFolder = QDir::homePath(); QString newFileName = dataFolder + "/" + fileName; QFile file(newFileName); if(file.exists()) { qDebug()<<"FILE EXISTs"; }leader. Exists() returns false. I don't understand what I'm doing wrong :-(
.the calling on QFile creates the file if it does not exist.

Problem with javascript:alert (document.lastModified)
After I've upgraded to Firefox 6.0.1 and 6.0.2 now today I can't get an answer to my javascript:alert (document.lastModified) help

You run this code through the address bar?
You can run is more JavaScript code via the address bar in Firefox 6 and later versions.
You see an error message in the tools > error Console.
Now, this code gets a security principal null for security reasons and has no effect (Bug 656433).
You must create a bookmarklet (keyword) and run the code by invoking this bookmark.NoScript can allow you to run this code through the address bar, see:

Creating a csv file, then send file contains an attachment...
I have a question to multiple segment...
I need to create a csv file and then attach this file to an e-mail. I have a general idea on how to get it going, but before I start coding I have a few questions...
These are the classes / pseudo-code...
- Create file, replace an existing one because just one instance of this file...
QString csvFile = QDir::homePath() "/ mycsvFileAttachement.csv";
QFile newFile (csvFile); - Data through the loop model and write each record in the file
Not sure how to do this part with C++. Any sample to show how to achieve?
- Create a new email and attach the newly created file... So, for this piece I was looking @ the MessageBuilder class...
https://developer.BlackBerry.com/Cascades/reference/bb__pim__message__messagebuilder.html
It would have been so much simpler to have the possibility to use the invoke framework to push a new message, user interface, but from what I've read, it is basically impossible to hang an attachment via the invoke framework. Is this correct?
- Display the user interface for new Message and wait until the message is pulled off by user

To send an email, the example message gives me all the code necessary to accomplish this feature. But I also want to provide a contact selector the user, any sample that shows how to do this?
If the file save location is important you want to prompt the user in the dialog box a file selector. They can save documents or the SD card, etc. If not, then create a temporary file, i.e. do not use QDir::homePath();
filePicker = new FilePicker();
filePicker-> setType(FileType:: other);connect to this kind can at least make a deleteLater()
Connect (filePicker, signal (Canceled (()), this, slot (filePickerCanceledSlot ()));
sign in here to get the name of the file to save on
Connect (filePicker, SIGNAL (fileSelected(const QStringList &)),
This, SLOT (filePickerSelectedSlot (const QStringList)));What about writing in the file, the QTextStream use for you help. Do something like this:
QFile file (fileName);
bstatus = file.open (QIODevice::WriteOnly);
If (! bstatus) {}
qWarning()< "failed="" to="" open="" file="" "=""><>
return;
}QTextStream out (&file);)
QListIterator
iter (myObjets); {whilte (ITER.hastNext ()}
MO = iter.next ();
the < mo-=""> field1 < ","=""> < mo-=""> Field2< ","="" ....=""><>
}
file-> close();
I don't know how to send it as an attachment. You can search for it on this forum because it's a frequently asked question. Myself I could never get send attachment to work the way I wanted so abandoned. And decided the user can only send the file as an attachment if they want to.
I hope it is of some value.

Hello
I want to know how to create a folder and a file inside a SD card and write data to the file.
I tried
QDir * dir = new QDir (QDir::currentPath() + "/... /...") ("/ removable/sdcard/MyFolder");
qDebug() < "path="" exists?="" "=""> < dir-=""> exists().
and it's all false,
I tried
QFile * zipFile = newQFile ("::currentPath() QDir +" "/... /... / removable/sdcard/MyFolder/filename.zip");
qDebug()
exists(). and it showed as false;
I checked access_shared and I am able to get the path to the SD card, please help
Thank & regards
Vishnu pascalp
QFile looks like just use open() with the correct attributes...

QDir QFile are just classes used to interface with the system files IO.

Cannot create a .db file in the assets folder
I am trying to create a quizz.db file in the current folder by creating first a temporary quizz.db in the folder data and then creating tables inside and then copy it in the current folder. By debugging code, it shows that the folder is created. But I can't find it in the current folder. Here is the code
#include
#include #include #include using namespace bb::cascades; using namespace bb::data; SQLTest::SQLTest(bb::cascades::Application *app): QObject(app) { const QString fileName = QString("quizz.db"); QString dataFolder = QDir::homePath(); QString newFileName = dataFolder + "/" + fileName; QTemporaryFile file(newFileName); // Open the file that was created if (file.open()) { // Create an SqlDataAccess object SqlDataAccess sda(newFileName); // Create a table called Employee in the database file sda.execute("CREATE TABLE Employee( firstName VARCHAR(50),lastName VARCHAR(50), salary INT);"); // Insert employee records into the table sda.execute("INSERT INTO Employee (firstName, lastName, salary) VALUES (\"Mike\", \"Chepesky\", 42000);"); sda.execute("INSERT INTO Employee (firstName, lastName, salary) VALUES (\"Westlee\", \"Barichak\", 55000);"); sda.execute("INSERT INTO Employee (firstName, lastName, salary) VALUES (\"Ian\", \"Dundas\", 47000);"); if(sda.hasError()) { } else copyFileToAssetsFolder("quizz.db"); } } void SQLTest::copyFileToAssetsFolder(const QString fileName) { QString appFolder(QDir::homePath()); appFolder.chop(4); QString originalFileName = appFolder + "app/native/assets/" + fileName; QFile newFile(originalFileName); // If I enable this `if` condition the code satisfies it and removes the quizz.db file and then it satisfies the next `if` condition and successfully copies the quizz.db file from `data` folder to `assets` folder. /*if(newFile.exists()) QDir().remove(originalFileName);*/ // this `if` condition is not satisfied. Which should mean the quizz.db file has been created on assets folder. if (!newFile.exists()) { // If the file is not already in the assets folder, we copy it from the // data folder (read and write) to the assets folder (read only). QString dataFolder = QDir::homePath(); QString newFileName = dataFolder + "/" + fileName; QFile originalFile(newFileName); if (originalFile.exists()) { // Create sub folders if any creates the SQL folder for a file path like e.g. sql/quotesdb QFileInfo fileInfo(originalFileName); QDir().mkpath (fileInfo.dir().path()); if(!originalFile.copy(originalFileName)) { qDebug() << "Failed to copy file to path: " << originalFileName; } } else { qDebug() << "Failed to copy file data base file does not exists."; } } // mSourceInDataFolder = newFileName; } If activate the commented "If" condition of "copyFileToAssetsFolder" int he removes already created quizz.db file in the current folder (that Im unable to find) and goes inside the next ' if' and copy the quizz.db created on the folder "data" of active fodler. But in any case I don't find the quizz.db in the current folder. I really need help with this quickly. Thank you.

Error creating the file (Permission denied)
Hello
I'm trying to create a file and write in some information from my application for debugging, but always return a QFileError on creation.
An example of code:
QFile data("log.txt"); if (data.open(QFile::WriteOnly | QFile::Text)) { QTextStream out(&data); out << "Debug information"; }else{ qDebug() << "Error opening log.txt: " << data.error(); qDebug() << "Error description: " << data.errorString(); }This return QFile code:
penError. Error description: 'permission denied '.How can I give write permissions?
Thanks for the help.

How to create a file name variable with the County and the date?
Objective: Create a file name variable with the County and the date
Error: get a lot of error. Do you know how to change my code?
Question: how to create a file name variable with the County and the date?
Mini code:
std::string * rawfilepath;
std::string * rawfilename;rawfilepath = "./shared/documents/";
RawFileName = rawfilepath + 'rawlog -' + 0 + '-.txt ';
QFile file (rawfilename);
If (file.exists ()) {}
rawfilenamecount ++;
RawFileName = "./shared/documents/rawlog-" + rawfilenamecount + "-.txt ';
}Thank you for your attention,
Thank tzander reminding me the idea. Method of cascades is not good for me because all of the kernel code is written by Native. If I change the channel to QString, I need to change a lot of codes.
Solution is below.
While (access (rawfilename, F_OK)! = - 1) {}
rawfilenamecount ++;
sprintf (format, RawFileName, rawfilenamecount);
fprintf (stderr, "file exists");
}Rawlog = fopen (rawfilename, "w"); Save the file in a specific path.
fprintf (rawlog, "System Time (ms)" ""); -

I have read and watched videos about the creation of an object of a class and calling its method in a different class. I'm still confused on how to do it properly. By using the code below if someone can explain how to properly call the method of objects from my hand.
Huh? You have NOT posted any 'hand' or any 'method of objects '.
If you need help with the code, you need to view the code.
The Java tutorials has dozens of trails "Classes and objects": what they are, how to create and how to use them.
https://docs.Oracle.com/javase/tutorial/Java/javaOO/classes.html
1. create an instance of a class
2. call to one or more of the public methods of this class
If the class has public static methods, you don't need to create an instance first.
I suggest that you work your way through these tutorials. They include the WORKING example code.

Failed to create photo memories
I use the mac on the Sierra photos app, update that became my mac perfect condition a paralyzed slug.
According to the help of photos I can create a memory of an album as follows:
- Click on an album under Albums in the sidebar.
- Click Show as memory.
- Scroll down and click on add to memories
My problem is that I do not see 'display in memory '.
This means that I have no way to create a slideshow. No idea why I don't see "display memory"?
Concerning
My problem is that I do not see 'display in memory '.
When you select an album in the sidebar, 'Show as memory' is under the search field in the toolbar.
It is only available for standard albums, not for the smart albums.

Node of automation is much more difficult to 'uncheck' than to 'create '.
I use logical X about 5 months now, and I felt a fairly frustrating relationship with interaction of automation. When I load automation, 'creation' of a knot of automation is simple... 1. click anywhere along the yellow line creates a node that is precisely where I clicked. However, "popping/unclicking/destroy" this same node takes anywhere from 3 to 6 clicks to work. I would love to be able to uncheck these nodes with the same exact ease with which I am able to create. No relief in this case would be great! Thank you
Double click on the node to remove it... as simple as when it was created... Click to create, double-click Delete.

Can I create a recovery bootable USB through disk utility?
My HARD drive is dying, I can't access my Macintosh HD partition anymore and I can't reinstall OS because I SMART errors. Before the format and reinstall the attempt to load slow my computer, random errors, etc. So I definitely think that the HARD drive is near death. My plan is to replace my HDD for a Virgin SSD, I perform this task several times on computers of the victory but for MAC, I wonder how I will load the new OS. Can I make a bootable USB with the recovery partition, but on a USB key tools? Unofrtunately I have more available Mac to create the USB bootable through itunes.
My computer is the MacBook Pro (13-inch mid 2010), I have also all original packaging somewhere, if there is a CD that I can use, I certainly can get too.
Any advice?
Thank you!
Apple have this to do a USB installation...
Create an installer for OS X - Apple support bootable
Another option is to use the diskmakerx.com application
You must have the OS installer downloaded to make these methods of work is probably not practice on your failed drive.
Both of these options are to run a 'normal' operating system too. The recovery partition is not 'normal '.
Another option is to use the Internet recovery mode if your Mac supports...
Computers that can be upgraded to use OS X Internet Recovery - Apple Support
On macOS recovery - Apple Support
Use wired ethernet for best results, since it will download a bootable OS & then download the installer of the OS also.
I suspect you have the update of the firmware installed to add this feature if it has been updated over the last 3 years
You may be able to generate a score of alternative recovery to another disk (such as a USB key) If you want to just "compensation of base OS.
OS X: on Recovery Disk Wizard - Apple Support
A last solution would be to clone your drive failing on an external drive (or use the new SSD in a proper case). That can be done in the modes of recovery via disk utility. Basically, you use a feature to "restore" to clone one volume to another. (I don't see clear instructions for the moment so ask if you want to pursue this option).
