I'm not sure I understand exactly what you did. If I understand correctly, you call a function called MoveOperation() in onclickEvent and perform the required operations for the move.
That seems correct, however, there is something I didn't include in the original post because I thought it was obvious. Add this at the end of your MoveOperation():
pEdit->ShowWindow(SW_SHOW); //Show the edit box
pEdit->SetFocus(); //Set focus to the edit box
pEdit->SetSel(0,-1,FALSE); //Select the text in the edit box

I am trying to make a game that can 'think'. This is a tic-tack-toe game. I was wondering how to make it. The basic layout uses arrays. The only thing I need to do is to make the computer 'Think'. Please reply with anything it doesn't matter what. I would appreciate it if they helped. Thanks.

Do a google on Tic-Tac-Toe algorithms - there is a lot of data out there!
My solution relies on "brute-force" because the grid is only 3 x 3. So an if-then tree can be constructed to handle every possible condition in the game with little effort.
There are only 3 possible starting positions - a corner, a non-corner/non-center, and the center.
There are a max of 5 moves per player.
If you assign every space on the grid a number that is twice the number before it, you'll end up with:
1 2 4
8 16 32
64 128 256
There are only 16 different ways that an opponent can have 2 out of 3 squares - and those 16 ways can be expressed as the sums of those numbered squares.
You can test for a condition where the opponent can win on the next turn by comparing the sums of the opponents rows, columns and diagonals (and subtracting the value of the computer's squares) against those 16 values.

Hi,
computer thinking games, oftenly use what is called 'heuristic' functions (search google for tic-tac-toe heuristic).
This means, that if you have a matrix (which represents the tic-tac-toe board game) then each cell receive a number defining the importancy of it. for example as we all know the most powerful cell in the tic-tac-toe board game, is the center cell (2,2). so you can give this cell the amount of 100 (arbitrary).
for starters thing of the values you can give for the cells. next when design the computer movement, search for the best value to move to (the highest is the best, the lowest is the worst)....
In computer science B.A every course that deals with A.I (artificial intelligence) explains heuristic. you also need to learn how to build a tree from the data and perform searches on that tree like (BFS - best first search) and others.....
hope i helped you to begin

It sounds like you are having difficulty mapping an event to a function.
(I make that assumption because event handling is the greatest common denominator of "click a button and pull up a web page" and "click a button and load a JPEG from disk")
An "event" is anything that a user can do with their input devices (typically mouse and keybopard) that results in your program being told something has happened (other events are generated by the system as well).
Windows informs your code that an event has happened by sending "Messages". Messages contain data that defines the name for the message and additional data that is pertinent to that specific message.
"Handle"ing that event is simply writing code that is executed in response to an event.
MFC passes information to your classes as events happen. For example - when a user double-clicks their mouse, Windows sends a message that tells your program that the mouse was double-clicked. For the double-click message, the additional data are the coordinates of where the mouse click was.
To get your program to respond to a button being clicked, you need to follow these steps:
1) Create an App in App-Wizard - make it Dialog based for learning. It is easier.
2) Go to the Resource view and look at your main dialog.
3) Add a button from the tool palette.
4) Edit that button's properties - name it IDC_DRAGON. For it's caption, enter whatever you want
5) Type Ctrl-W to open Class Wizard
6) Make sure the class selected is the Dialog box class for your main dialog
7) Highlight the button's ID (IDC_DRAGON) in the Object IDs listbox
8) You'll see 2 messages in the "Messages" listbox that Windows recognizes for that type of highlighted object
9) Double-click on the BN_CLICKED message
10) You will see a small dialog that opens and asks you for the name of the function that will Handle that Event (clicking the button). You can usually just use the default. Click OK.
11) What you have just done is add an empty Message Handler for code that will be executed when a user clicks that button.
12) Notice that the text in the Messages listbox is now bold for the message BN_CLICKED. This means that Class Wizard has created a Handler for that Message
13) Look at the Member Functions listbox - you should see that the function name you entered (or accepted as the default) for the handler for the BN_CLICKED Message for the IDC_DRAGON object is highlightd.
14) Double-click that highlighted function and you will be taken to your source code - right at the spot where you need to write the code to handle that event.
15) Just to verify that you are handling the event - write the following code where Class Wizard positions you:
MessageBox("Dragon Button", "BN_CLICK Handler");
16) If you do it correctly, you will see the message box when you click the Dragon button
If this explanation was too simplistic, I apologize. It sounded like you needed help in handling events.
If you complete steps 1-16 correctly, then you will be ready to write the actual code you need to respond to a button click.

Hi all,
I've created a MFC extention dll project. in the stdafx.h file i've wrote:
#undef _GUI_LIB_EXPORT_
#ifdef _EXPORT_GUI_LIB_
#define _GUI_LIB_EXPORT_ __declspec(dllexport)
#else
#define _GUI_LIB_EXPORT_ __declspec(dllimport)
#endif
i have 2 exported classes, 1 is a dialog, the other one is a button:
1) class _GUI_LIB_EXPORT_ CMyDlg : public CDialog
2) class _GUI_LIB_EXPORT_ CMyBtn : public CButton
i use an MFC exe project to test my dll.
in the stdafx.h i also write :
#undef _GUI_LIB_EXPORT_
#ifdef _EXPORT_GUI_LIB_
#define _GUI_LIB_EXPORT_ __declspec(dllexport)
#else
#define _GUI_LIB_EXPORT_ __declspec(dllimport)
#endif
when i compile, it seams to recognize the dialog exported class (CMyDlg) but for the CMyBtn class i get
warning C4273 - inconsistent dll linkage. dllexport assumed.
can any1 help???
i am desparate here..
thanks in advanced,
Yaron

Hi,
Usually the color of the dialog box by default is grey, how do i change the color. How can i make the dialog box change its color as soon as i clickon a button.
Thanks and regards

Hi,
there are several ways to change the dialog bk color:
1) use SetDialogBKColor() method in the InitInstance()
2) use OnColorCtl() Message handler
3) draw a rectangle that will cover the entire dialog
i prefer to use the second method
here is an example code on how to use it:
in the *.h file write down:
protected:<br />
afx_msg HBRUSH OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor);
in the *.cpp file write an entry in the message map:
BEGIN_MESSAGE_MAP(CYourDlg, CDialog)<br />
ON_WM_CTLCOLOR()<br />
END_MESSAGE_MAP()
implenent the OnColorCtl , write down:
HBRUSH CGUIBaseDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) <br />
{<br />
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);<br />
<br />
if (CTLCOLOR_DLG == nCtlColor)<br />
hbr = m_brushDlgBk;<br />
<br />
<br />
return hbr;<br />
}
notice the use of brushDlgBk.
in the *.h file define the brush:
CBrush m_brushDlgBk;
in the *.cpp file in the constructor of the dialog
create the brush:
m_brushDlgBk.CreateSolidBrush(RGB(200,200,200))// the color you chose place here
that should do the trick....
to switch the colors on a click just use 2 brushes and return the proper one in the OnCtlColor method according to a flag indicating the click
hope i helped ya

Hi,
Could someone please give me some tips - or even better, link ot some examples - on how to create an EditStreamCallback function? I have searched the net and several coding forums, but can't find any solid information, even MSDN.
I have a Rich Edit text box, and whilst I can currently save to a .txt file using GetDlgItemText() and WriteFile(), this method is very limited and I really want to save as an RTF file. I have read the info on EM_STREAMOUT and EditStreamCallback, and it seems that these are the functions I need to use in order to save as an RTF file.
If anyone can tell me how to write a callback function that will write an .rtf file, link to some more comprehensive info, or just give me some general tips, I would be really grateful.
Incidentally, I am using the straight Win API SDK with _no_ MFC.
Many thanks!

Hi!
In some class, the adress of "this" change from method to other method of the same class.
For example,
void X::doNothing()
{
doNothing2(); // adress of "this" = 0x053014e4
}
void X::doNothing2()
{
// adress of "this" = 0x053014f0
}
This happen only in some class of my project.
The "this" adress is essential for me because I use it to do object research by comparing adress.
Do someone have an idea why in some class this will happen and other not?

Multiple base clases with virtual methods?
Poor pointer casting? (don't use (X *), use static_cast <x *=""> ())
Tim Smith
I'm going to patent thought. I have yet to see any prior art.

Hi!
I don`t use poor pointer casting. In fact, I often use dynamic_cast on object having multiple base class (and the basic base class is inherited virtually).
Can it cause a problem?
I`m stocking "this" adress in a vector to do futur search base on adress difference.
Thanks

Perhaps an implicit copy is being made somewhere? You can try explicitly specifying the copy constructor and setting a breakpoint inside it.

Hi all,
I am deriving a class from CWnd, I just want to display images from a CListImage. What I really need is to display images like Emoticon Window in messenger like applications.
I saw an article in C# which creates an emoticon window, I tried myself but were unable to do in VC++/MFC
Please anybody help me to create a window like the one I need.
Thanks.
