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
.
