(portion of...) QByteArray to UInt

Hi,

I have this QByteArray whose first 2 bytes are, say 0x11 and 0x08.

I'd like to extract those 2 byte into a quint16.

I've tried myByteArray.left(2).toUInt() with no success..

Since these 2 bytes represent a value in little-endian format I must extract them to a quint16 and then qToBigEndian the value.

Could someone please point me the proper way to do it?

TIA,
Pedro.

Code:

---

uint val;
QByteArray ba;
memcpy(&val, ba.constData(), 2);

---

or

Code:

---

uint val;
QByteArray ba;
val = (ba[1] << 8) | ba[0]; // order reversed, as you wanted it

---

how about this:

1. extracting the chars seperately with at(int)
2. anding their appropriate shifted versions
3. adding the two results

Code:

---

char c1 = myByteArray.at(0);
char c2 = myByteArray.at(1);
 
quint16 myuint = 0;
myuint += (c1<<8)&0xff;
myunint += byte2&0xff;

Excellent! Again in your debt wysota!
Thank you very much!
