Read a csv file from Internet

[abghosh]

Hi

I am a newbee in Qt4. I am trying to read a file which is on the web, e.g.:
from http://download.finance.yahoo.com/d/...1c1ohgv&e=.csv.
without downloading it.

I am able to read a local csv file. But when I am trying to read this file, the file cannot be found.

Also I want to refresh the reading every 5 secs.

How can I do it?

Thanks in advance.

How are you reading from the net ?

Hi aamer4yu

That is the problem I am facing. I cannot read the file online. If I download it to local system, everything is fine.

WHAT are you using to access the file on the net?

Maybe have a look at QNetworkAccessManager/QNetworkRequest/QUrl ?

A typical usage might be manager->get(QNetworkRequest(QUrl("http://download.finance.yahoo.com/d/quotes.csv?s=DLF.NS&f=sl1d1t1c1ohgv&e=.csv")));

The call is asynchronous - you'll get your data in the appropriate slot.

You HAVE to download an item to read it. That's how all browsers do it. You can use QTemporaryFile to create a temporary file on the filesystem, and delete it when you're done.
