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);
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.

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

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