windows注册表的基本使用——示例

上网找好多资料发现一个问题就是太老。例如只有RegCreateKey而没有RegCreateKeyEx用法详解，自己摸索了几个小时终于基本用到的几个函数都试用了一遍。

 

下面代码已经通过编译测试

  1 // test__regedit.cpp : 定义控制台应用程序的入口点。
  2 //
  3 
  4 #include "stdafx.h"
  5 
  6 #include <windows.h>
  7 #include <iostream>
  8 
  9 #include <vld.h>
 10 
 11 void test__create_regedit()
 12 {
 13     LPCTSTR lpSubKeyGOCOM = TEXT("SOFTWARE\\GoCom5.5");
 14     HKEY hKeyGOCOM = NULL;
 15     DWORD dwDisposition;//是否存在
 16     if ( ERROR_SUCCESS==::RegCreateKeyEx(HKEY_LOCAL_MACHINE, lpSubKeyGOCOM, 0, NULL, REG_OPTION_NON_VOLATILE, KEY_ALL_ACCESS, NULL, &hKeyGOCOM, &dwDisposition) )
 17     {
 18         std::cout << "RegCreateKeyEx successful" << std::endl;

129 
130 int _tmain(int argc, _TCHAR* argv[])
131 {
132     test__open_regedit();
133     test__create_regedit();
134     return 0;
135 }

 

由于时间关系还有很多函数没有用到，等以后以机会在放上来吧（例如：RegQueryInfoKey等）
