RegGetValue' : undeclared identifier?
can you help me figure out why im getting this error.. here is my code
Code:
#include <string>
#include <stdio.h>
#include <windows.h>
#include <tchar.h>
#include <fstream>
#include <iostream>
using namespace std;
ifstream fin;
ofstream fout;
#define MAX_KEY_LENGTH 255
#define MAX_VALUE_NAME 16383
void main()
{
fout.open("value.txt");
string name = getenv("computername");
fout << "workstation name: " << name << endl;
// DO NOT TOUCH... TOOK FROM MICROSOFTS WEB PAGE!! except where I replaced i with K (for keys
// and added V (for values) this way I get enumkeys and enumvalues to loop when I want.
