Downloading file problem

[Kaluss]

Hello,
im trying to develop download app, but I stuck on following problem:

1)I sen a download request by QNetworkAccessManager
2)On finished event I got QNetwork *reply which size is correct
3)but the size of: reply->readAll().length() is incorrect and when I save the file is too small.

Does anywone know where is the problem or what Im doing wrong?

Hard to say without seeing your code. However, if you do this,

qDebug() << reply->readAll().length();
// then open file and
file.write(reply->readAll());

qDebug() << reply->readAll().length();
// then open file and
file.write(reply->readAll());

To copy to clipboard, switch view to plain text mode 

You get an empty file because there is no more data to read after the first call to readAll().

Generally situation looks like this:
void UpdateMgr:nDownloadingFinished( QNetworkReply* reply )
{
if( reply->error() == QNetworkReply::NoError )
{
qDebug() << "Size of downloaded file:" << reply->size();
qDebug() << "Size of saved file:" << reply->readAll().length();
}
}

Size of downloaded file: 11902976
Size of saved file: 11894784

Why????
