How to delete a file within thread using
I try to delete a file, but i get error it's using by other progressing. Specially, I use a thread to copy content file but during copying, i want to crop down copy progressing and delete the file not intact.
How to disconect that progress to file deleted.
if the file is opened by your application you need to make sure that you call QFile::close() on it.
If the file is locked by another process/application there is nothing you can/should do.
I try to use:
but not working.
Get a error:
@error: C2352: 'QFile::close' : illegal call of non-static member function@
i don't believe that this is the actual code you are using!
Why don't you post the correct code when you expect us to help you?!
I assume you call a member of type QFile out of a static method, right?
I'm really sorry you,
I get error above when i use:
in my class. So, I try other away,
But also file not deleted.
destination is variable QDir type
QFile::close() is not a static function so remove this line and use it like in line 4.
QFile file("c:/des/1 (1).iso");
qDebug() << "QFile::remove()" << file.remove();
qDebug() << "QFile::errorString()" << file.errorString();
What are the outputs of this code?
Hi, outputs as below:
QFile::errorString() "The process cannot access the file because it is being used by another process.@
you can use "ProcessExplorer":http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx and check which process is holding the handle to that file.
If it's your application check your code again where you "open":http://qt-project.org/doc/qt-4.8/qfile.html#open it and make sure you close it properly. If it's another application there is nothing you can do...
Thank you very much,

Let me see again.
