注册表的应用问题！

[zhongxd]

在我的应用程序中，我想将一些属性保存到注册表中，那位大侠可以将它的应用过程（用到的函数等）和我简单的说一下么，谢谢！

CString szRegSetting = _T("SOFTWARE\\Your Ap\\Your Data");

CString GetRegString( LPCTSTR szKey, LPCTSTR szRegSetting )
{
CString strRet = CString(_T(""));

if (szKey != NULL)
{
HKEY hKey;

if(RegOpenKeyEx(HKEY_LOCAL_MACHINE, szRegSetting, 0, KEY_QUERY_VALUE, &hKey) == ERROR_SUCCESS)
{
UCHAR szBuf[MAX_PATH];
DWORD dwBufLen = MAX_PATH;

if (RegQueryValueEx(hKey, szKey, NULL, NULL, (LPBYTE) szBuf, &dwBufLen) == ERROR_SUCCESS)

RegCloseKey(hKey);

上面的四个函数分别是保存与读取int值与string值到注册表中的function，

szRegSetting的值你可以自己随意指定！！他表示要写到注册表中的具体位置！！
