RegRestoreKey总是调用失败？

[MissionSuccess]

以下是代码，发现返回值是5.

BOOL RestoreKey( HKEY hBootKey, LPCTSTR lpszKeyName, LPCTSTR lpszPath )
{
	assert( hBootKey );
	//assert( lpszKeyName );
	assert( lpszPath );
	BOOL bRet = FALSE;

	//1. 申请备份权限
	HANDLE hToken;
	TOKEN_PRIVILEGES tkp;
	if( !OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken) )
		return FALSE;
	LookupPrivilegeValue( NULL, SE_RESTORE_NAME, &tkp.Privileges[0].Luid );//申请SE_RESTORE_NAME 权限
	tkp.PrivilegeCount = 1;
	tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
	AdjustTokenPrivileges( hToken, FALSE, &tkp, 0, (PTOKEN_PRIVILEGES)NULL, 0 );

	//2. Open key
	HKEY hKey = NULL;
	if ( ERROR_SUCCESS != RegOpenKeyEx(hBootKey, lpszKeyName, NULL, KEY_ALL_ACCESS, &hKey) )
		return FALSE;

	//3. Restore Key
	/*if ( ERROR_SUCCESS != RegRestoreKey(hKey, lpszPath, FALSE) )
	{
		bRet = FALSE;
	}*/
	int nRet = RegRestoreKey( hKey, lpszPath, FALSE ); //返回5
	if ( ERROR_SUCCESS != nRet )
	{
		bRet = FALSE;
	}
	else
		bRet = TRUE;

	RegCloseKey( hKey );
	return bRet;
}

5 --- Access Deny,估计你的程序权限不够，或者系统不允许你操作这个注册表

那怎么写才可以啊？

[Quote=引用 3 楼 lactoferrin 的回复:]
REG_FORCE_RESTORE
[/Quote]
error C2664: “LookupPrivilegeValueA”: 不能将参数 2 从“long”转换为“LPCSTR”

[Lactoferrin]

RegRestoreKey( hKey, lpszPath, REG_FORCE_RESTORE);

谢谢楼上，搞定了。
