Download Manager's file handle

[pka64pka]

Hi!

How can I get the file which is downloaded by download manager?
Can I use the file for reading during the download?

I followed the example described in http://wiki.forum.nokia.com/index.ph...ogrammatically
and I get an event EHttpDlCompleted, but when I try to get the file handle:

void CTMDownloader::HandleDMgrEventL(RHttpDownload &aDownload,
        THttpDownloadEvent aEvent )
{
...
    switch ( aEvent.iDownloadState )
        {
...
        case EHttpDlCompleted:
            {
            RFile file;
            aDownload.GetFileHandleAttribute( file );
            }
}

The download manager crashes. If I try to set in the begining the file handle it also crashes the DMgr server.

        RFs fs; 
        fs.Connect();
        RFile file;
        if(file.Open( fs, _L("C:\\Data\\Videos\\hvf.mp4"), EFileWrite) != KErrNone)
            {file.Create( fs, _L("C:\\Data\\Videos\\hvf.mp4"), EFileWrite);}
        TInt error = iDownload->SetFileHandleAttribute( file );

error is -15 : server terminated.
What can be the problem?

Thanks for your help!

Just to share our experinces:
- DMgr opens the file exclusively so it can not be opened by other application even when progressive download is set.

- We also tried to get the chunk but it also crashed.

Our sollution:
- We implemeted simmiliar thing with RHttpSession it just works.

In my case I'm handling the RFile myself, by setting the file in the
RHttpDownload::SetFileHandleAttribute just after the download has been created (CreateDownloadL) and before Start'ing it.

You should have to make handling of the file (open and close) by yourself.

void CDownloadXML::ConstructL()
{


iDMgr.ConnectL( KMyApplnUid, *this, ETrue );

iUiReg = CDownloadMgrUiLibRegistry::NewL( iDMgr );

idMgrUserInteractions = &iUiReg->RegisterUserInteractionsL();

iMgrDownloadsList = &iUiReg->RegisterDownloadsListL();

iDMgr.DeleteAll();
}

void CDownloadXML:: DownloadXMLDoc(TDesC& aFileName, TPtrC8 aCodUrl)

{
TUint32 iapId(0);
CCommsDatabase* cdb = CCommsDatabase::NewL(EDatabaseTypeIAP);
CleanupStack::PushL(cdb);

CCommsDbConnectionPrefTableView* commDBView = cdb->OpenConnectionPrefTableInRankOrderLC(ECommDbConnectionDirectionOutgoing);
if(commDBView->GotoFirstRecord() == KErrNone)
{
CCommsDbConnectionPrefTableView::TCommDbIapConnectionPref pref;
commDBView->ReadConnectionPreferenceL(pref);
iapId = pref.iBearer.iIapId;
}

CleanupStack::PopAndDestroy(commDBView);
CleanupStack::PopAndDestroy(cdb);

User::LeaveIfError( iDMgr.SetIntAttribute( EDlMgrIap, (TInt32)iapId ) );


RHttpDownload& download = iDMgr.CreateDownloadL(URL,retVal);

download.SetStringAttribute( EDlAttrDestFilename, filename ); //silent save prob till now...

TBool silattr(ETrue);

download.SetBoolAttribute(EDlAttrSilent,silattr);
download.Start();

}

void CDownloadXML::HandleDMgrEventL (RHttpDownload &aDownload, THttpDownloadEvent aEvent)
{
switch ( aEvent.iDownloadState )
{
case EHttpDlCompleted:
{
iDMgr.DeleteAll();
break;
}
}
}

Forget about what is wrong in the code. Your problem can be solved if you copy the file before it is being deleted.

You can do it in the "Download Complete" case of the download events.
