How to get reference to a file?

[zgulser]

Hi,

I have a process that creates a file in the application path. I need to get a reference to this file in order to flush or close it.

Making only;

QFile myFile(nameOfTheFileIwantToRefer);

QFile myFile(nameOfTheFileIwantToRefer);

To copy to clipboard, switch view to plain text mode 

would be enough?

Not really sure what you mean. You can't flush or close file opened by process A from within a different process B.

Hi again,

I mean I'm opening a file from another dll. aFter a while I want to access this file ( somewhere at D: ) via QFile in order to flush it.

Then you need to get the exact same handle from that dll. Opening a new handle (through QFile) won't help.

use QDataStream and setDevice() function in it.
Hopes help you !

Tell me Ali Reza, why would using QDataStream help anything here?

[Ali Reza]

by setDevice function, we can manage an IO device such as read specific bytes
If i underestand correctly.

such as read specific bytes

Is that what this thread is about?
