Save the text in the file system

How would I go about recording a string text in QT to the file system?

Way the easiest is to use QFile and streams:

QFile file("out.txt");
if (!file.open(QIODevice::WriteOnly | QIODevice::Text))
  return;

QTextStream out(&file);
out << "The magic number is: " << 49 << "\n";

QString s("abc");
out << s << "\n";

There are more samples in docs:

http://Qt-project.org/doc/Qt-5.0/QtCore/QFile.html

If you store application settings, QSettings might be a better fit.

Hello

I am trying to save the file on SD card

          String url = "file:///SDCard/text.txt"          FileConnection conn = (FileConnection) Connector.open(url);      OutputStream out = conn.openOutputStream();   // unreachable code      out.close();      conn.close();

Not to be confused... YOU read my previous POST.

Also answer me...
How do you want to save the file?
1. replace or add to the file in the folder?
2. create a new file in the folder?

If you answer is first, change your code in a more dynamic way

-Save the opened Excel file
rglist: = OLE2. Create_Arglist;
OLE2. Add_Arg (arglist, file_name_cl);
OLE2. Invoke (Binder, 'SaveAs', Arglist);
OLE2. Destroy_Arglist (arglist);

So then you can give it

-Save the created Excel file
rglist: = OLE2. Create_Arglist;
OLE2. Add_Arg(arglist,'c:\export\newexcelexport.xls');
OLE2. Invoke (Binder, 'SaveAs', Arglist);
OLE2. Destroy_Arglist (arglist);
Your file will be saved in the "C:\export\" a folder with the name newexcelexport

I use to manage my DSL modem via an ip address. When I enter FF8 I wonder where to save the file. Why and how can I prevent the FF8 to do this?

I use to manage my DSL modem via an ip address. When I enter FF8 I wonder where to save the file. Why and how can I prevent the FF8 to do this?

And now, whenever I'm in an ip address that I wonder if I want to download the file.

This happens when the modem server does not send the file in text/html, but with a different MIME type.

I tried adding index.html in the event that the server can send this file as text/html.

If your DSL modem has a support Web site, then you can try asking it there advice on how to configure the server modem.

Qosmio F20-136: scanned TV guide channel - save the file so you can recharge?

I have a Qosmio F20 - 136 running XP Media Center. My question is does anyone know the name of the file that has the channels scanned so that if I do a re scan and don't get all channels from the list, because of my reception antenna I can re - load the file on the system with a complete list?

What happens, if I make a new analysis of the channels of television at home I don't get that nearly 20 tv channels, but if I take the laptop to work, where I guess it's a better reception from the transmitter, I travel 35 channels found. I would like to save the file when its 35 channels scanned and have the opportunity to replace it in the directory, if I do a re scan at home.

Thank you.

Hello Mike

Your validation list is very impressive and you should be an expert Qosmio. ;)
I have F20 too and I also noticed that I can't watch all the channels available on cable TELEVISION here at home.

Have you already found something interesting about it?

Save the file on the user's desktop

Hi all, just a simple question (I hope!)

I am writing a program and I want to save the file .txt output to the office. Of couse, different computers will have on their desktop to different directory paths (for example C:/Documents and Settings/Bob/Desktop - the user name will be different in all cases).

Is there a specific command that you can use to specify what system you are looking for the office, regardless of the rest of the path of the directory? If it makes no sense at all.

Thank you!

Yes.Use get the system directory in a file i/o under file constants.

Why DAQmx read 200714 error when you save the file?

In particular vi that I created, I have 3 analog inputs coming in and are graphically represented. If I choose to save the information to a file, a dialog box appears and I can choose what to save it under. If I take too long to save the file (aka about 8-10 seconds if the sample read rate is 500/s) then I get this error once the file has been saved:

Error-200714 occurred at .vi DAQmx Read (analog 1-d NChan DBL 1Samp)
Possible reasons:
Acquisition stopped because the driver could not transfer the data from the device to the computer's memory rather quickly. This was due to limitations of the computer system.
Reduce your sample clock rate, the number of channels in the task, or the number of programs on your computer that is running simultaneously.

Why the DAQmx bed vi I have this problem when the vi has been idle for 10 seconds then I choose where to save the file? How can I fix this error?

Hi child of pre-school age,

I think your error might be caused by the read buffer overflow. my suggestions for you would be to either the following four ideas:

1. stop the acquisition before writing the file. This should mean that the DAQmx Read function will no longer be reading and therefore does not generate an error.

2. If you still want to read the data but also write data as well, I think you'd be best suited for use live TDMS. TDMS allows the user to stream to a reading of filewhilst.

3. the configuration backup dialog box file before starting the acquisition. Download the user to enter all data in the file before you start to acquire.

4. change the buffer to unlimited so that you have enough time to navigate the record window.

If you send your VI I can advise others

He is so little known about your configuration - because the forums MS Answers do not ask for information, when a new question is asked.

If you run some kind of RAID configuration, you might do better if you describe your RAID configuration and after the actual event that you see in the event log (is it event ID 55?). Then maybe you will get some ideas of the Microsoft Support engineer who might actually work.

You see just this event in the paper at random times or is it when you try to run a specific operation and if yes, what operation triggers the event? Here is an article of MS to help get you started, but if you use Google to search for the error message, you can find more ideas:

http://support.Microsoft.com/kb/246026

If sfc/scannow solves your problems, I'll send you (or your charitable organization preferred) US $100.

Here's how to publish events to the event to display the log files:

If you double-click on an event, it will open a window of properties with more information. On the right are black up and down arrow keys to scroll through the open events. The third button that looks like two overlapping pages is used to copy the details of the event in your Windows Clipboard.

When you find an interesting event that occurred at the time of your question, click on the third button at the top and arrows to copy the details and then you can paste the details (right click, paste or CTRL-V) the text in detail here for analysis. Remove all personal information from your information after you paste If you are forced to do so.

If you paste an event, it will look something like this annoying system startup event:

Event type: Information

To get a fresh start on any log of the event viewer, you can choose to clear the log (the log backup is available), and then reproduce your problem, then just look at the events around your show and troubleshoot events that are happening when you have your question.

You can search for events on the World Wide Web and get ideas. It's where people events they see and then to the top of their questions, ideas and solutions:

Writing a file with the file system

I'm trying to export a file in javascript and write it in the retentive memory.

I use 2 WebWorks (BB10.2) and the plugin 'com.blackberry.io '.

I am able to access the file system

window.requestFileSystem (window. PERSISTENT, 0, {function (fileSystem)
fileSystem.root.getFile (sFile, {create: true}, {(fileEntry) function)
Console.log ("Cordova about to create the writer of the entry in the file");

Console.log (JSON.stringify (fileEntry));
fileEntry.createWriter ({function (writer)
Console.log ("Cordova about to write to the file");

Writer.onwrite = function (evt) {}
Console.log ("write successful:" + fileEntry.fullPath);
Alert (fileEntry.FullPath);
};

I'm sorry that my original post has seemed to be cut short.

The problem is when the call actually:

Writer.Write (new Blob ([surlabasedesdonneesdufabricantduballast], {type: "text/csv;})) charset = utf - 8 "}));

I discovered also for what was causing the problem. The debugger on the pc seems to interfere with the process. As soon as I removed the breakpoints it started working.
