I'm working on an aim profiler program in C++ using VC6, and
I'm trying to take the last login name for AIM from the registry and store it in a variable. I'm not that experienced with the Win32 Api, but I'm trying. Here's my code: (I took it off a code example site, then butchered it for my needs, which is most likely why it doesn't work)
HKEY hKey;
REG_SZ dwSize = "";
REG_SZ dwDataType = "";
REG_SZ dwValue = "";
if(::RegOpenKeyEx(HKEY_CURRENT_USER,
"Software\\America Online\\AOL Instant Messenger\\CurrentVersion\\Login",
0,
KEY_QUERY_VALUE,
&hKey) == ERROR_SUCCESS)
{
//Get Last Login Name from opened Key
if(::RegQueryValueEx(hKey,
"Screen Name",
0,
&dwDataType,
&dwValue,
&dwSize) != ERROR_SUCCESS)
{
// Close key
::RegCloseKey(hKey);
}
// Close key
::RegCloseKey(hKey);
}
These are my includes, which I'm not sure about either
#include "stdafx.h"
#include "conio.h"
#include "fstream.h"
#include "stdio.h"
#include "iostream"
#include "cstdlib"
#include "windows.h"
#include "winreg.h"
it gives me a bunch of error about undeclared identifiers in the top 4 lines and it also says:
"error C2440: '=' : cannot convert from 'char [1]' to 'int' This conversion requires a reinterpret_cast, a C-style cast or function-style cast"
for the top 4 lines.
I'm probably doing a lot wrong, but hopefully someone can tell me what I need to do. If you look in regedit at "Software\\America Online\\AOL Instant Messenger\\CurrentVersion\\Login" you'll see the key that says "Screen Name" and then the last login, I want that last login screename in a variable.
