Enum registry keys problem

[vbx_wx]

can someone help me ,i am trying to enumarate some registry keys,i doesnt get me any error,just the output is wrong:

void Registry::open_key(HKEY Key , char* subkey)
{
	RegOpenKeyEx(Key , subkey , 0 ,  KEY_ENUMERATE_SUB_KEYS | KEY_QUERY_VALUE  , &hkey);

}

void Registry::querry_info_key()
{
	RegQueryInfoKey(hkey , 0 , 0 , 0 , &sub_keys , 0 , 0 , 0 , 0 , 0 ,  0 , &filetime);
	if(sub_keys)
	{
		cout << "There are " << sub_keys << " keys" << endl;
	}
}

void Registry::enum_key()
{
	for(DWORD i = 0; i < sub_keys; i++)
	{
		RegEnumKeyEx(hkey , i , name , &size , 0 , 0 , 0 , &filetime);
		cout << i << ":" << name << endl;
	}
}

void Registry::run()
{
	HKEY keys[] = { HKEY_CLASSES_ROOT , HKEY_CURRENT_USER , HKEY_LOCAL_MACHINE , HKEY_USERS , HKEY_CURRENT_CONFIG };

	//for(int i = 0 < 5; i++)
	//{
		open_key(keys[1] , "Software");
		querry_info_key();
		enum_key();
	//}
}

int main()
{
	Registry x;

	x.run();



}

>>enum_key()

Change that for loop to a while loop. RegEnumKeyEx() will return ERROR_NO_MORE_ITEMS when done.

int i = 0;
while( RegEnumKeyEx( /* blabla */)  != ERROR_NO_MORE_ITEMS )
{

}

still the same output :(

You have to reset the value of size on each loop iteration

void Registry::enum_key()
{
	int i = 0;
	while( RegEnumKeyEx(hkey , i , name , &size , 0 , 0 , 0 , &filetime) != ERROR_NO_MORE_ITEMS)
	{
		cout << i << ":" << name << endl;
		i++;
		size = sizeof(name);

	}
}
