Re: GetParent - C / C++ / MFC Discussion Boards

why this is not getting parent ?
while it is a child

Are we talking about an MFC class here, or is this a 3rd party solution?

I'm a little curious that a member variable would have the name of GetParent.

for member variable to have the parent information, you should set it for dynamic created control, other wise it assume as NULL!

Why did it take you two posts to ask a question?

Also since you posted code that won't even compile yet you claim you are executing said code, there is no reason to believe we have been given the requisite information needed to solve the problem.

class tab *t=new tab;

that's not going to compile on my system.

Not so good, since the number of '+' should be some power of two.
Anyway, have a look at ***new*** WTF++ compiler as well.

1. Please post the actual code (not a crappy-simulating one).
2. Whenever you create a child dialog window, you should pass a pointer to the parent as second parameter (from MSDN [^]):

virtual BOOL Create(
UINT nIDTemplate,
CWnd* pParentWnd = NULL
);

if you rely on the default parameter then dialog's GetParent will return NULL.

Where are you setting the parent window at? If you don't set it, why would you expect anything other than NULL to be returned?

I implemented Ping(by ICMP) function and PortScan(by connect function).
it is to check that computer is on the network.
but these functions are spending too much time.
Ping function is delayed by recvfrom function and
PostScan function is delayed by connect function.
I wanna impove the speed.

now it is single processing. so i think it implement multithread and

thank you for reading my article

Pinging a computer is not a reliable way of determining if it is available/online.

Think again. Adding additional threads to an application may improve its design but it will surely slow it down. Too much context switching.

What? Are you suggesting you can use broadcasting to implement port scanning of remote machines if only you knew how to receive responses? You better do some more studying on Sockets because you are totally lost. Since the most frequent use of Port Scanning is for malicious purposes, why do you need to do this?

Hi Guys,

I'm not much of a programmer, so bear with me please.

I'm trying to program a standard Ant Algorithm/Ant Colony Optimization in C++, to search through a basic maze of open and closed (1 for open, 0 for closed) nodes to simulate a basic network.

Now I have the program functioning correctly for one ant, just runs through it once until its had its maximum number of moves or it finds the destination node.

I am trying to convert this into a class, so I can have multiple instances of the class (multiple ants) going through the network at once. My question is; how do I accomplish something like this? Currently, for my Ant Class I have :

class ant {

coordStruct route[300];
pheremoneStruct location[1];

public:
void set_route (int,int);
void set_location (int,int);
void set_coordPheremone (int,int,int);
} ant;

Will this work? If I perform all of the calculations and such outside of the class via get/set functions? or should I move the actual methods themselves into the class like below?

class ant {

coordStruct route[300];
pheremoneStruct location[1];

/* CALCULATIONS TO DETERMINE NEXT MOVE HERE */

public:
void set_route (int,int);
void set_location (int,int);
void set_coordPheremone (int,int,int);
} ant;

I hope I've explained this clearly... But any help is appreciated, or any links to the code of something similar to give me an idea of what to do would also be helpful!

Thanks a lot.

Put the method in the class.

This is after all, what encapsulation is all about - encapsulating the data and functions used to operate on it all into one neat packaged unit.

If it were me, I'd make it a virtual function, so that if, for whatever reason, you then need to simulate a different species of ant that makes decisions on its path differently, just inherit from this class and re-write the nextMove method.
