Solution 2

You may use the data member for the purpose (though getting the buffer for write access is really a bad idea):

C++

QByteArray array;
//..
BYTE * pByte = reinterpret_cast<byte*>(array.data());

Thank You.. Thats great.. myself 5 for it..

Anyway, if you really need to write access the buffer, make a copy of it and modify the copy.

OK, 5, proposed as Answer.

Thank you. Now that we're good friends what about a debate about physics? On the serious side, how can you propose an answer (I'm not able to or, probably missing something...)?

Sergey Alexandrovich Kryukov 9-Mar-11 18:44pm

Sorry, could you remind me..? What answer?

You wrote (3rd message above):"OK, 5, proposed as Answer". How did you 'propose'? I cannot find a way to (I'm probably missing something...).

Sergey Alexandrovich Kryukov 10-Mar-11 1:51am

Yes, I understand, it's not clear. I used to ask such question myself. Somebody explain me that this is such a tradition. I think myself it does not really serve the purpose. OK, let me do it in my way... see my next comment...
