Re: reading& writing binary data block by block
0x means hex notation - so 0xDE means value hex DE which is 13 (D) * 16 + 14 (E) which is decimal 222
The example in post #2 showed how to write /read blocks of binary data.
how can i convert my char or string data to this format '0xDE'
If you mean
Code:
string block1 = "DEDEDEDEDEDEDEDEDEDEDED"; // hex data
where does this data originate from? having it produced in the right format first is better than trying to convert.
What exactly are you trying to achieve?
