Write into file

goetz

If you're not in need of a human readable/editable file, I would recommend [[Doc:QDataStream]] together with "operator<<".

Thanks for your quick reply.

The output file should look like this:
MSH|^~&|LABOR||MEDIKA||201101010032||ORR^O02|7500421|P|2.3|||NE|AL||
MSA|AA|2714415|
ORC|OK|7500421^MEDIKA|7500421^LABOR||IP||^^^^||||||||||

I write the file under win and is reading under unix. Carriage return closes the lines. According the Qt Assistant no input parameter like QString or QQueue at “operator<<”. I guess I can't get rid of the iteration:(

No, of course you need a bit of custom parsing to handle that. QTextStream and QString::split may come in handy.

You did not answer the question regarding human readability.

The questions are:

must the resulting file be human readable and/or editable

is the file written using Qt only

is the file reaad using Qt only

Answer all of these with yes or no.

The result will influence the way to store and retrieve the data.

Sorry,

The answers:

yes, it must be editable by vi or nano
yes, under windows
no, reading is under unix

On Unix you can have Qt too :-)

Anyways, as the blocker is the "editable by...", I would go like this:

@
QStringList sl;
// fill it somewhere

QFile file("output.txt");
if (!file.open(QIODevice::WriteOnly | QIODevice::Truncate)) {
// error processing here
break;
}

QTextStream ts(&file);
ts << sl.join('|');
ts << "\r"; // or "\n";
file.close();
@

For the QQueue there is no join() method, you will have to iterate through all the elements:

@
QQueue<QString> stringQueue;

QString delim; // emtpy string
foreach(const QString &e, stringQueue) {
ts << delim << e;
delim = "|";
}
ts << "\r"; // or "\n"
@

He would make all of us drive a motorcycle while eating muffins and ban rain in general. I'm voting yes!
