AI for tic tac toe can be anything from simple as hell and fairly complex.
1) This simplest method of AI is to just iterate the array gameboard and check for NULL's, the first NULL = empty space which means...the computer should pick this spot.
Of course this doesn't leave for very interesting game play (not that tic tac toe would or could)
1) To spice things up a little you could add some more advanced AI and do something like...instead of take the first available spot...search the game board for a potential opponent win and fill that gap before they do, I think this would work best if the computer started second.
2) Then you could use a game tree (i'd never heard of that before). Something I was attempting to do in my comp sci class was actually dynamically store players moves in a db while executing and use this growing db as a method of choosing the next mostly likely win-win scenerio.
The second approach would best be suited for the computer if it starts second...but would provide night and day difference in AI...
If you sit down and think about it for a sec or two you'd probably think of a better way of doing this, but heres just a quick idea on how to implement this.
char move[9];
Then create an array of move's (tree) initialized with X and O's in different places. Use this tree to choose your next move.
The one downside to this method (which I just realised while writting this...  is that you'd need one 'move' for each possible scenerio...to be able to use this method effectively...thats a whole lot of move[n]={X,O,O,X,O,X,X,O...}
This is only one possible solution to a problem which has many.

Hi all,
I was wondering if there was a way to get/set the delay time between when a key is pressed and it starts to auto-repeat. Any info would be great. 
TIA

Consider the following array, whose contents are NOT sorted:
int Ids[10]={12,4,22,67,2,5,11,33,6,10};
If a binary search routine is written to search through this array, what will happen? For example,
Will the program abort, since the array is not sorted? or
will the binary search routine be successful, but inefficient? or
Will the binary search fail? or
???

Binary search on a non-sort list will yield a LOT of erronious "not found"s.

Sort it first. Binary search expects a sorted array. It won't crash your program, but you will get wrong results for your search if the array is unsorted.

To receive that message, it has to be owner drawn. Which also means you have to implement the WM_DRAWITEM and other messages.

Hi !
I am Ergin. I've been building a database program using CFormView. Now I need to get rid of the scroll bars but I can't. I mean I don't want it to be resizable or scrollable (I want fixed). I couldn't do that.
And as a second one I have a CTabCtrl inside and when I put a picture behind it , it ends up in the middle of the CTabCtrl. I think Tab is a hollow control. How can I correct this ??
If you answer I will be very pleased. Tomorrow I have to show the program off but still I couldn't finish it.
byeeee

If the scroll bars are appearing automatically, it is likely that your dialog resource is larger than the default frame client area size.
Add a handler for the WM_GETMINMAXINFO in the CMainFrame class. You can then specify the min and max size for your windows.
<br />
void CMainFrame::OnGetMinMaxInfo(MINMAXINFO FAR* lpMMI) <br />
{<br />
lpMMI->ptMaxSize.x = 700;<br />
lpMMI->ptMaxSize.y = 500;<br />
lpMMI->ptMaxTrackSize.x = 700;<br />
lpMMI->ptMaxTrackSize.y = 500;<br />
lpMMI->ptMinTrackSize.x = 700;<br />
lpMMI->ptMinTrackSize.y = 500;<br />
CFrameWnd::OnGetMinMaxInfo(lpMMI);<br />
}<br />

A quick way to remove the scroll bars is in the OnSize handler for the form view is to call:
SetScaleToFitSize(cx, cy) ;
You may also need to r-size any controls to porperly fit on the form.
As for the bitmap appearing in the middle of you tab control, check the tab order of the control in the resource editor (CTrl+D) and make sure that he bitmap is before the tab control to get he correct plot order.

Hi,
I just created an app using VC++ and I think it needs a little spice so, I want to include graphics in my app, how can I put an image in the background (not 16 colors, 256+) like in msn messenger. I would like an image and I could put my controls on top of it. Actually when I do that today, my bitmap takes the whole place and all the controls are under it. And also, I want to make my image fit the entire application canvas.
Help me if you can please.

Use stretchBlt, and paint the image in the WM_ERASEBKGND message.

First of all, my equipment:
************************************Win2k Server******************************
Name: iras
Workgroup: HTBL
Domain for Windows: htlpinkafeld.at
Domain for Netware: htbl\
User: testuser@htlpinkafeld.at (in htlpinkafeld.at\edvoschueler)
No Password!! (only for testing)
******************************************************************************
***********************************Win2kProf (Workstation)********************
Programming Language: Microsoft Visual C++ 6.0
MSDN: April 2001
Workstation is in the same network like win2k server (of course!)
******************************************************************************
First step:
BINDING TO AN USER (testuser@htlpinkafeld.at)
I read that i should use the function
HRESULT ADsOpenObject(
LPWSTR lpszPathName,
LPWSTR lpszUserName,
LPWSTR lpszPassword,
DWORD dwReserved,
REFIID riid,
VOID FAR * FAR *ppObject
);
To do so, i had to import the following:
Header: Adshlp.h
Library: ActiveDS.Lib
PROBLEM:
The 5th parameter takes values which are neither in Adshlp.h nor in ActiveDs.Lib. So!! I found out that the needed stuff is in another lib called
"ADSIID.lib". BUT some declarations are redefined in ADSIID.lib! Because the program needs this lib to work right i even can't let it be. Then i found out that this sometimes happens, god knows why!, and that i should insert the prefix "/force:multiple" into the menu project\settings\Link\"Project Options". I did so and the result was a list like the following, please don't scare:
