Unable to open zipped file which is zipped with Quazip

[zgulser]

Hi,

After I zip my data using the code below, I can create the zip file and it's size is quite logical. But when I attempt to unzip it using WinZip, Winzip gives me an error.

I'm working on Microsoft VS 2O1O and using Qt 4.8.

Any ideas?

QByteArray LoggerManager::packFiles(const QString& p_name, const QByteArray& p_BytesToBrCompressed)
{
	QString testZip = p_name;
    QuaZip zip(testZip);
 
    zip.setFileNameCodec("IBM866"); /* or Windows-1250 */
 
    if(!zip.open(QuaZip::mdCreate))
	{
        qWarning("testCreate(): zip.open(): %d", zip.getZipError());
		return NULL;
    }
 
	QString loc = qApp->applicationDirPath() + "/logs/error_log/";
 
    QFileInfoList files=QDir(loc).entryInfoList();
    QFile inFile;
    QFile inFileTmp;
    QuaZipFile outFile(&zip);
    char c;
	QByteArray compressedData = "";
 
    if(!outFile.open(QIODevice::WriteOnly, QuaZipNewInfo("", "")))
	{
 
		qWarning("testCreate(): outFile.open(): %d", outFile.getZipError());
		return NULL;
    }
 
    //while(inFile.getChar(&c)&&outFile.putChar(c));
 
	for(int i=0; i < p_BytesToBrCompressed.size(); i++)
	{
		outFile.putChar(p_BytesToBrCompressed.at(i));
	}
 
    if(outFile.getZipError()!=UNZ_OK)
	{
		qDebug() << "AQQQQQQQQQQQQQQQQ!!";
		qWarning("testCreate(): outFile.putChar(): %d", outFile.getZipError());
		return NULL;
    }
 
    outFile.close();
 
	if(outFile.getZipError()!=UNZ_OK)
	{
		qWarning("testCreate(): outFile.close(): %d", outFile.getZipError());
		return NULL;
    }
 
	QFile reader(p_name);
	if(QFile::exists(p_name))
	{
		if(reader.open(QIODevice::ReadOnly))
		{
			compressedData.append(reader.readAll());
		}
	}
 
    inFile.close();
 
    zip.close();
 
    if(zip.getZipError()!=0) 
	{
        qWarning("testCreate(): zip.close(): %d", zip.getZipError());
		return NULL;
    }
 
	qDebug() << "Compressed Data: " << compressedData;
 
	return compressedData;

Hi again,

The problem was in;

if(!outFile.open(QIODevice::WriteOnly, QuaZipNewInfo("", "")))

if(!outFile.open(QIODevice::WriteOnly, QuaZipNewInfo("", "")))

To copy to clipboard, switch view to plain text mode 

so replacing the above line with;

if(!outFile.open(QIODevice::WriteOnly, QuaZipNewInfo("syd_barrett.txt")))

if(!outFile.open(QIODevice::WriteOnly, QuaZipNewInfo("syd_barrett.txt")))

To copy to clipboard, switch view to plain text mode 

solved the problem.

Unfortunately in Quazip, there is nothing to alert the user for this case at least.

Anyway, the problem solved and thanks.
