C++ 读写注册表

最近自己搞了一下操作注册表的程序，自己对于windows编程真的不了解，于是上网找博客，结果网上的博客，发现没有一个对的，路径好多的符号写反了。。。于是把自己能用的代码放上来。

代码：

#include <iostream>
#include <algorithm>
#include <cmath>
#include <vector>
#include <string>
#include <cstring>
#include <atlbase.h>
#include <Windows.h>
#pragma warning(disable:4996)
using namespace std;

void read_dword()//读取操作表,其类型为DWORD
{
HKEY hKEY;//定义有关的键，在查询结束时关闭
//打开与路径data_Set相关的hKEY

LPCTSTR data_set = _T("Software\\Chicony\\Lenovo1");

//访问注册表，hKEY则保存此函数所打开的键的句柄
if (ERROR_SUCCESS == ::RegOpenKeyEx(HKEY_CURRENT_USER, data_set, 0, KEY_READ, &hKEY))
{
DWORD dwValue;//长整型数据，如果是字符串数据用char数组
DWORD dwSize = sizeof(DWORD);
DWORD dwType = REG_DWORD;

if (::RegQueryValueEx(hKEY, _T("123"), 0, &dwType, (LPBYTE)&dwValue, &dwSize) != ERROR_SUCCESS)
{
cout << "错误：无法查询有关的注册表信息" << endl;
}

cout << dwValue << endl;
}
::RegCloseKey(hKEY);
}

void read_reg_sz()//读取操作表,其类型为REG_SZ
{
HKEY hkey;
LPCTSTR data_set = _T("Software\\Chicony\\Lenovo1");

if (ERROR_SUCCESS == ::RegOpenKeyEx(HKEY_CURRENT_USER, data_set, 0, KEY_READ, &hkey))
{
char dwValue[256];
DWORD dwSzType = REG_SZ;
DWORD dwSize = sizeof(dwValue);
if (::RegQueryValueEx(hkey, _T("wangchong"), 0, &dwSzType, (LPBYTE)&dwValue, &dwSize) != ERROR_SUCCESS)
{
cout << "无法查询有关的注册表信息" << endl;
}
cout << dwValue<< endl;
}
::RegCloseKey(hkey);
}

void write_dword()//在\Software\\Chicony\\Lenovo1文件夹下写入一个test111的子键，设置其名称为Name，其值为6
{
HKEY hkey;//定义有关的hkey，在查询结束时要关闭
HKEY hTempKey;

DWORD dwValue = 6;
DWORD dwSize = sizeof(DWORD);
DWORD dwType = REG_DWORD;

LPCTSTR data_set= _T("Software\\Chicony\\Lenovo1");
if (ERROR_SUCCESS == RegOpenKeyEx(HKEY_CURRENT_USER, data_set, 0, KEY_SET_VALUE, &hkey))
{
if (ERROR_SUCCESS == ::RegCreateKey(hkey, _T("test111"), &hTempKey))
{
if (ERROR_SUCCESS != ::RegSetValueEx(hTempKey, _T("Name"), 0, REG_DWORD, (CONST BYTE*)&dwValue, sizeof(DWORD)))
{
cout <<"写入注册表失败"<< endl;
}
}
}
::RegCloseKey(hkey);
}

void write_reg_sz()
{
HKEY hkey;
HKEY hTempKey;
char m_name_set[256]="China";

DWORD len = strlen(m_name_set) + 1;
LPCTSTR data_set = _T("Software\\Chicony\\Lenovo1");
if (ERROR_SUCCESS == ::RegOpenKeyEx(HKEY_CURRENT_USER, data_set, 0, KEY_SET_VALUE, &hkey))
{
if (ERROR_SUCCESS == ::RegCreateKey(hkey,_T("test1112"),&hTempKey))
{
if (ERROR_SUCCESS!=::RegSetValueEx(hTempKey,_T("Name"),0,REG_SZ,(const BYTE*)m_name_set,len))
{
cout << "写入错误" << endl;
}
}
}
::RegCloseKey(hkey);
}

void write_binary()
{
HKEY hkey;
HKEY hTempKey;
BYTE m_name[10];
memset(m_name, 0, sizeof(m_name));
m_name[0] = 0xff;
m_name[1] = 0xac;
m_name[2] = 0x05;
m_name[3] = 0x4e;

LPCTSTR data_set= _T("Software\\Chicony\\Lenovo1");
if (ERROR_SUCCESS == ::RegOpenKeyEx(HKEY_CURRENT_USER, data_set, 0, KEY_SET_VALUE, &hkey))
{
if (ERROR_SUCCESS==::RegCreateKey(hkey,_T("test111"),&hTempKey))
{
if (ERROR_SUCCESS != ::RegSetValueEx(hTempKey, _T("Name"), 0, REG_BINARY, (unsigned char *)m_name, 5))
{
cout << "写入错误" << endl;
}
}
}
::RegCloseKey(hkey);
}

void delete_value()
{
HKEY hkey;
LPCTSTR data_set = _T("Software\\Chicony\\Lenovo1\\test1112");

if (ERROR_SUCCESS == ::RegOpenKeyEx(HKEY_CURRENT_USER, data_set, 0, KEY_SET_VALUE, &hkey))
{
if (ERROR_SUCCESS != ::RegDeleteValue(hkey, _T("Name")))
{
cout << "删除错误" << endl;
}
}
::RegCloseKey(hkey);
}

void delete_key()
{
HKEY hkey;
LPCTSTR data_set = _T("Software\\Chicony\\Lenovo1");

if (ERROR_SUCCESS == ::RegOpenKeyEx(HKEY_CURRENT_USER, data_set, 0, KEY_SET_VALUE, &hkey))
{
if (ERROR_SUCCESS != ::RegDeleteKey(hkey,"test1112"))
{
cout << "删除错误" << endl;
}
}
::RegCloseKey(hkey);
}

int main()
{
read_dword();
read_reg_sz();
write_reg_sz();
write_binary();
delete_value();
delete_key();
system("pause");
return 0;
}

读写注册表之后的效果如图，自己windows编程这块还要努力学习，好多的地方都不懂，希望能和大家多多交流。
