Cannot open binary file in Momentics IDE using C++

Hello

This has more to do with C++ with qml but I'm stuck for awhile now and maybe someone here knows the answer.

What I want to do in my app is I open and read a file once I clicked on a button. This is my code to open the file:

// after button is clickedfstream file;
file.open("S:/filepath/file.abc", std::ios::in|std::ios::binary);

if(!file.fail()) qDebug() << "File not found!";
else if(!file.good()) qDebug() << "Can't open file";
else if(!file.is_open()) qDebug() << "Error opening file!";
else{
    qDebug() << "Start opening file ...";
    if(file.is_open()) {
        qDebug() << "File is open!";
    }
}

First of all I don't get the "file not found" - message so the! file.fail () command works very well and that the file exists.

But when I then check if the file is opened with! file.good () it gives me my error message that the file is not opened.

My version of test in Visual studio, has worked well. But not in the momentics IDE it does not work. Can someone give me a clue what to do?

I'll hazard a guess may be for the user to select a file and then read it in this case, you will need to use a FilePicker...

http://developer.BlackBerry.com/native/documentation/Cascades/UI/pickers/filepicker.html

Using what happens then a path valid + file name with which you can use to switch to QFile...

http://developer.BlackBerry.com/native/reference/Cascades/QFile.html

As a hint of Windows has its own way of doing things, UNIX (and in this case QNX with Qt/Cascades on top) another.

  • Bad installation file for Momentics IDE 2.1.1

    Hello

    I just downloaded Momentics IDE for Linux 32 b 2.1.1 and I got this message after you run the binary file:

    cz7asm@cz7asm-Z97-D3h $./momentics-2.1.1-201411071638.linux.x86.run ~/Downloads

    Now, it's very strange because I have donwloaded the file twice and the checksum remains the same. I suspect that there is a bug in the installation process. Also list of MD5 checksum on the website (http://downloads.blackberry.com/upr/developers/downloads/momentics-2.1.1-201411071638.cksum) does not show the MD5 sums:

    Of course, there is only the sizes of different generations.

    Could someone give me some comments on this? I couldn't find any contact for people behind releasing Momentics IDE using this forum was the only option I could think.

    Thanks for any help.

    Petr

    The question of the checksum must also be fixed right now as well.  Give him another try and let me know if you still have problems.

  • "Extraction failure: cannot open output file" error message when installing new drivers

    Hello, I am trying to install new drivers for my HP Photosmart C4385 printer.  I downloaded the complete drivers of features for Windows XP 32-bit, and when I start to install (extract), I get the error message:

    Extraction failed

    Cannot open output file

    And the process ends.  He arrived at about 85% extraction every time.

    No idea why?  I called HP, but no longer under warranty they wanted money, which I think as absolutely ridiculous - not even give me basic support?  Poor, poor customer service.

    Hi GIJeff12,

    Temporarily disable any AntiVirus/Antispyware software.

    Cut the installer on your desktop then click on the Start Menu, click computer, double-click on the C: drive and paste the installler here.  Now try a right click on the installer for your printer, choose 7-Zip and choose Extract the files, and then click Ok.  If the installation program extracts now correctly, follow these steps.  If it does not extract, let me know.

    Disconnect your printer from the PC.  Restart your PC.

    Open the newly extracted folder and double-click the setup application to start the installation (the installation application will probably have the same icon as the original installation software that you downloaded).  Connect the printer to your computer when you are asked.

    If it was a success, re - enable your security software.

    Best wishes

  • Error message - Windows cannot open this file after downloading program

    After several days in offline mode, I went online to update Microsoft Security Essentials and click on analysis complete.  It took an hour.  After that, I found that all my programs were virgins, almost of all of the standard microsoft Microsoft Security Essentials is.  I tried to download it again, plus others such as adobe acrobat, but all said "windows cannot open this file".  I asked help from Microsoft but received access denied.  I feel like an illegal immigrant, as all the doors were closed.  What does that mean?  My OS would be illegal?  It is Windows XP and was purchased new in the retail price in 2004 and has only once been out of my hands when I sent it repairs and have 2 GB ram added.  Any ideas?

    If you use windows XP, it is not possible to install Microsoft Gadgets on it. Microsoft Gadgets are optimized for Windows Vista and Windows 7 only.

    However, you can use your favorite search engine to download third-party gadgets which can serve the purpose.

    Note: Using third-party software, including hardware drivers can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the use of third-party software can be solved. Software using third party is at your own risk.

    Hi JRCLNSIN100,

     

    Welcome to Microsoft Answers Forums.

    We would like to get some more information from you to help solve your problem. You better, please answer the following questions.

    ·         What is the disk you use to reinstall?

    ·         Is this a recovery or reinstalling the disc you are using?

    ·         When exactly do you get this error message?

    ·         What is the edition of Windows Vista, you try to install?

    ·         How old is the drive that you are using?

    ·         How are you starting the installation process?

    After researching the error 0x8007000D code is essentially due to file corruption and a problem with the drive itself.

    First check if you have scratches or dust on the disc and clean the surface and try again.

    To check if the disk is wrong, you will need to copy the contents of the DVD to the hard drive and try to install using that.

    To perform a flat installation of Windows Vista, follow these steps.

    Note The hard disk must have at least 3 GB of free space on the disk for the Windows Vista installation files. The hard disk must have at least 15 GB of additional disk space to install Windows Vista. For more information about system requirements for Windows Vista, see the Microsoft Web site at the following address:

    http://www.Microsoft.com/Windows/products/windowsvista/editions/SystemRequirements.mspx

    1. Insert the Windows Vista installation disc.
    2. Start Windows Explorer.
    3. In Windows Explorer, click to select the drive for the Windows Vista installation disc.
    4. On the Edit menu, click select all.
    5. On the Edit menu, click copy.
    6. Click to select the hard disk you want to contain the flat installation files.
    7. On the file menu, point to new, click the folder, type Windows Vista Setupand then press ENTER.
    8. Double-click the Windows Vista Setup program, and then click Paste on the Edit menu.
    9. Double-click Setup.exe, and then follow the instructions that appear.

    See the link below for more information on flat installation.

    How to perform a flat installation of Windows Vista

    http://support.Microsoft.com/kb/928902

    This problem can also occur if the firmware of the DVD drive is defective or obsolete.

    If the step above does not resolve the question suggests that you install the latest drivers for the DVD player on the computer.

    For more information please visit the link below.
