注册表问题－－如何获得键值？

[fengwd]

注册表信息如下：
[HKEY_LOCAL_MACHINE\SOFTWARE\Network Associates\ePolicy Orchestrator\Agent]
"ComputerName"="FENGWD"

我怎么才能把"FENGWD"读到一个字符串中？

我试着用了以下函数，但是好像我用得不对，谁能给我仔细讲讲啊，谢谢！

lRet = RegOpenKeyEx(
HKEY_LOCAL_MACHINE,
"SOFTWARE\\Network Associates\\ePolicy Orchestrator\\Agent",
0,
KEY_READ,
&hResult
);
lRet = RegQueryValueEx(
HKEY_LOCAL_MACHINE,
"SOFTWARE\\Network Associates\\ePolicy Orchestrator\\Agent",
NULL,
NULL,
(LPBYTE )abyData,
&dwNum
);

void GetProfile(LPTSTR section, LPTSTR key, LPBYTE lpData, DWORD cbData)
{
HKEY key1,key2,key3,key4;

if (ERROR_SUCCESS==RegOpenKeyEx(HKEY_LOCAL_MACHINE,"Software",0,KEY_READ,&key1))
{
if (ERROR_SUCCESS==RegOpenKeyEx(key1,"Network Associates",0,KEY_READ,&key2))
{
if (ERROR_SUCCESS==RegOpenKeyEx(key2,"ePolicy Orchestrator",0,KEY_READ,&key3))
{

if (ERROR_SUCCESS==RegOpenKeyEx(key3,section,0,KEY_READ,&key4))
{
RegQueryValueEx(key4, key, 0, 0, lpData, &cbData);
RegCloseKey(key4);
}
RegCloseKey(key3);
}
RegCloseKey(key2);
}
RegCloseKey(key1);

}

}

char flag[255];
GetProfile("Agent","ComputerName", (unsigned char *)&flag,2);

结果存在flag中

自己搞定了
：）

lRet = RegOpenKeyEx(
HKEY_LOCAL_MACHINE,
"SOFTWARE\\Network Associates\\ePolicy Orchestrator\\Agent",
0,
KEY_READ,
&hResult
);
lRet = RegQueryValueEx(
hResult,
"ComputerName",
NULL,
NULL,
(LPBYTE )abyData,
&dwNum
);
