storing data in hexadecimal format

[aj2903]

hii....
i want to store data into file in hexadecimal format.

How can it be done ?

Follwing is the code I tried :




QFile fileC("test_1.hex");
QTextStream outC(&fileC);


unsigned char cData = 47;
outC << cData;l



The code writes 47,but in Char Format.How can we conver it into hexadecimal

Don't use QTextStream. Use QFile::write() instead.

if you want to store a single character, see QString::arg(), there are overloads that let you specify the base (choose 16 for hex). If you have more data, QByteArray::toHex() might interest you as well.

outC << showbase << hex << uppercasebase << uppercasedigits << cData;

How about using QDataStream instead of QTextStream? QDataStream provides a serialization of binary data. The examples of data/text stream are part of the documentation.
