I've tried possibly everything.

e.g. string = "0x1337";
I'll use strtol or strtoul to convert the string to DWORD but I get the decimal equivalent. I've also tried using std::hex but DWORD is assigned the decimal value.

String = "0x1337", DWORD =4919

I want DWORD to = 1337

just create your own atoi function... this thread and the one below it.. they worry me...cmon these things are super simple

It's all binary data. How you display that data is up to you.

Code

int x = 4919;
printf("0x%X\n",x);//Prints 0x1337
printf("%i\n",x);//Prints 4919

Need to store it in DWORD variable to be used further via ReadProcessMemory

A DWORD is just a typedef for unsigned long..

Code

DWORD dwVar = 0x1337;

I'm aware... But i'm trying to make my DwORD = "0x1337" via the string

not assigning the value itself.

There's an old deprecated function called "itoa" you could use.

0x1337 is just a binary number in base 16.
4919 Is just a binary number in base 10.
0001001100110111 is just a binary number in base 2.

Code

int main()
{

    char* szVal = "0x1337";
    DWORD dwVal = 0;

    printf("%s\n",szVal);

    dwVal = strtol(szVal,0,0);

    printf("%i\t0x%X\n",dwVal,dwVal);

    return 0;
}

Edit: Minor change on the base 2.

Did you try something like this?

Code

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char** argv) {

    char * str = "0x56f67";

    long int ans = strtol(str, NULL, 16);

    fprintf(stdout, "ans->%d\n", ans);

    return (EXIT_SUCCESS);
}

Considering it's a string. 0x1337 is ASCII. Convert the ASCII representation to Binary then Binary into Hex.

Which isn't hard at all.

Considering Binary is base 2, 11011 in binary would be 27 (Base 10)
Considering 4 bits are a representation of a 'char' let's split this up. 0001|1011 (leading zeros)
1011 = 11
1 = 1 so 0x1B

Think I'm being misunderstood. I need to take the value FROM the string and then ASSIGN the value to DWORD.

String value = "0x1337"; //Value wont be assigned like this
DWORD importValue;

I don't want to print the value; I want to assign it to my DWORD variable.

Is this C or C++? Everyone above seemed to assume that it was C yet none of that was even specified. Here's how you get the value of 1337 from the hex string "0x1337" into a DWORD variable in C++:

Code

#include <iostream>
#include <windows.h>
#include <sstream>

int main()
{
  DWORD val;
  char str[] = "0x1337"; // DWORD = 4919
  std::istringstream isstrm(str+2);
  isstrm >> val; // provide check for success/failure here
  std::cout << val << '\n'; // value = 1337
}

If you want the hexadecimal value itself to be stored in the dword (4919 (which is the same as 0x1337) and not 1337 (in decimal)) then:

Code

#include <iostream>
#include <windows.h>
#include <sstream>

int main()
{
  DWORD val;
  char str[] = "0x1337"; // DWORD = 4919
  std::istringstream isstrm(str);
  isstrm >> std::hex >> val;
  std::cout << val << '\n'; // value = 4919
}

^0xDEAD is it just me or are you guys purposely fucking around with those code tags?
It seems to me they have weird characters. I can view the code when i'm quoting.

It's just you unless you don't understand C++ syntax.. Reinstall or try another browser.

It's weird, it was doing it in incognito mode. I guess it was the browser. It was completely as if you guys were trolling OP. Seemed quite funny until i hit 'quote' and realized it was the browser
