Problems Encoding to Base64

[racinglocura07]

I am having problems encoding a file to base64.

I want to send a pdf by mail so i have to encode it to base64

When i do this:

QString data;
QFile file(filename);
file.open(QIODevice::ReadOnly | QIODevice::Text);
 
while (!file.atEnd())
{
     QByteArray line = file.readLine();
     data += line.toBase64();
}

QString data;
QFile file(filename);
file.open(QIODevice::ReadOnly | QIODevice::Text);

while (!file.atEnd())
{
     QByteArray line = file.readLine();
     data += line.toBase64();
}

To copy to clipboard, switch view to plain text mode 

The string data seems to content all the information, but if i attached it into a mail i could not open the file

I hope you could help me

Sorry for my bad english
