How to read the Binary data from QFile to buffer of type BYTE*???

How to read the Binary data from QFile to buffer of type BYTE*???

I assume that BYTE is some typedef or macro that is equivalent to char.

QByteArray and QIODevice::readAll(). You can access the bytes through QByteArray::data().

For me it looks like you expect that we're gonna solve all your issues for you - a while ago you've posted the same question here: link to thread
Please, can you kindly tell us what have you tried so far ? Because it looks like you are saying "I don't want help, I want a solution".

Note: I merged the threads, so this message was originally a response to the post while it was at a different place! (Lykurg)

While reading the same file for the second time.. It returns null in the buffer..
I am using the following code::

QByteArray buf;
buf=file.readAll();

The above code is inside the while loop. If it enters for the second time.. buf value becomes null. Pls help me...

So what you are trying to do is read the entire contents of the file more than once?

Yes.. That is the case

Well, then it is nonsense. Simply do something like:

Code:

---

buf += buf;

---

. If you still want to read the file again, use QIODevice::reset().

Added after 19 minutes:

I am getting the values till the last loop runs. After that nothing is present in the buffer.

Am using the following code:
int pos1=file.pos();
buf=file.read(size);
int pos2=file.pos();
strcpy(buffer,buf.data());

PLS HELP ME..

Stop asking the same question over and over - it rapidly annoys people who might be inclined to help.

You already have the answer to this in

As I mentioned earlier, a Byte (or is that BYTE) is usually typedef or macro for a "char" on every platform I have handy. So a BYTE* or Byte* is a char*. Equating these two has nothing to do with Qt, it is straight C++.

So, the order of responses gets a little messy here because I merged the thread. But we really do not need 4 (in letters: four) threads on that topic.
