注册表不能添加键
用C++调用WINDOWS API：RegCreateKeyEx、RegSetValueEx在注册表中增加子键以及键值。函数执行结束后未看到新键值。代码如下：
HKEY hKey = NULL;
char buffer[MAX_PATH];
DWORD dwDispos = REG_CREATED_NEW_KEY;
char szNewKeyName[MAX_PATH] = "Software\\Microsoft\\WindowsNT\\CurrentVersion\\Winlogon\\Notify\\NTServer";
LONG lRet = RegCreateKeyEx(
HKEY_LOCAL_MACHINE,
szNewKeyName,
0,
NULL,
REG_OPTION_NON_VOLATILE,
KEY_ALL_ACCESS,
NULL,
&hKey,
&dwDispos);
if(ERROR_SUCCESS != lRet) return;
RegSetValueEx(hKey, "Asynchronous", 0, REG_DWORD, (BYTE*)1, 1);
strcpy(buffer,"C:\\Hooks\\HookAPI.dll");
RegSetValueEx(hKey, "DllName", 0, REG_EXPAND_SZ, (BYTE*)buffer, strlen(buffer));
RegCloseKey(hKey);
