I'm trying to convert a String of hex to ASCII, using this:

public void ConvertHex(String hexString){    StringBuilder sb = new StringBuilder();    for (int i = 0; i < hexString.Length; i += 2)    {        String hs = hexString.Substring(i, i + 2);        System.Convert.ToChar(System.Convert.ToUInt32(hexString.Substring(0, 2), 16)).ToString();    }    String ascii = sb.ToString();    MessageBox.Show(ascii);}

but I get an out or bounds exception, I'm sure its a glaring error but other code I have tried does not work either. What am I doing wrong?

I have a function that takes in a value for an address in memory as a string (user input). It is input is taken in as a hex value

char * address = new char[16];address = "fff85044";

How would I convert that string into a readable address value?A sort of stoh (string to hex) function if it exists

I need to format a dictionary with multiple integer lists as hex in python 2.7.

I've found a way to format integers from a dictionary as hex. In this example the hex will work, the hexlist will not.

dict = {   "hex": 0x12,   "hexlist": [0x13, 0x14]}print("{hex:x}, {hexlist:x}".format(**dict))

(Python Sting Formatting - Real Python)

And there is also a way to print a integer list as hex using:

''.join('{:02X}'.format(hex) for hex in hexlist)

(Format ints into string of hex)

But I can't figure out how to combine the two...

I am trying to convert a printf output to a std::string variable. I have the following for loop:

for(i=0; i<53; i++) {    printf("%02X", pbRecvBuffer[i]);}

The output of this loop are hex values like: 01445420434F2... My first attempt was using stringstream as the following:

stringstream os;for(i=0; i<53; i++)     os << std::hex << pbRecvBuffer[i];std::cout << os << std::endl;

unfortunately this is given me the wrong result. Maybe someone just see it directly and can help me out.

What is the best way to convert a variable length hex string e.g. "01A1" to a byte array containing that data.

i.e converting this:

std::string = "01A1";

into this

char* hexArray;int hexLength;

or this

std::vector<char> hexArray;

so that when I write this to a file and hexdump -C it I get the binary data containing 01A1.
