I have a visual c++ program, it worked nicely for data processing.
Recently I added a edit box and add more code in the "next" subroutine.
The program is complied and generated *.exe successfully. This routine
should be invocated by pressing "Next" button.
Now when I run the program and push the "Next" button, I got:
<data_proc mfc="" application="" has="" encountered="" a="" problem=""
and="" needs="" to="" close.="" we="" are="" sorry="" for="" the="" inconvenience.="">
I tried to display some variable values at the right beginning of
the subroutine Next, it seems the program even not reach the point.
I do not know how to fix this. I need a help.
Thanks

Set a breakpoint in the Next() method and single-step through it from that point.

Consider removing these. Used incorrectly, which it looks as though they are, can lead to all sorts of unwanted problems.

I tried to set-up a breaking point inside "Next", but the program did not go that far (even the breaking point at the beginning of the "next") and stoped to give the error message.
I am thinking some of the array size in the program is too big causing overflow. That may be the problem.

Does the "Next" button have an ON_BN_CLICKED() handler? What does the message map for CData_vib_procDlg look like?

Hmmmm, if you've set a breakpoint in the Next() method and it is not being hit, I do not know what the problem is.
You mentioned something about an array. Does your program have them? Are they on the stack or the heap?

Now I found the array size is too big (global array - stack ?)
I get into the Next subroutine. I put a few breaking point and I checked the reading
all right.
However, I got:
"Debudg assertion failed."
what is the problem and how to fix it ?
Thanks

That's hard to say without knowing what line of what file asserted.

Are there any necessary apis that I should know?
I think my question was too short to understand. I want to disable internet using(such Web browsing,Chat or anything using internet) by press a button and can use internet again by press another button.
I want to know how to stop internet in windows 98.
I'm not good at English sorry.

I have seen your See Here, and read all that, What it does not explain is the Syntax of Forwarding a Function. DEF Files seem to have gone out of fashion to the extent that the only help the IDE gives, is, (in my version anyways), that All you can do in a DEFFile, can be done better by using command line options for the Linker/ Compiler. I know that not to be the case, but hence my question.

I want to draw a bitmap,(droughts for example)on dialog,
at mouse's coordinate when it's pressed !
Could you help me !
Lgx

 This is Not a simple Problem, and a Full solution for your own custom application will resort to a long list of API's
The Outline would be as follows:-
-Create a Dialog with a Bitmap Resource in it.
-Assign a Bitmap
-In the Dialog, implement the OnPaint Method to paint the Bitmat,taking account of where you want it painted.
-Use the WM_MOUSEBUTTON messages to capture the mouse when it is clicked over the immage
-Use the WM_MOUSEMOVE messages to track the mouse, and to issue WM_PAINT messages to keep the image following the mouse.
(The Latter is not as simple as it seems)as you will discover.
You will also see that the easier UpdateWindow Call does not work for this in a dialog, it only sends a WM_PAINT after you finally release the mouse button.
As I said, Not a simple task, there is not a single API available that does the lot, Also, not a task for beginners(Choose something simpler, i.e. Move the Image to where the mouse was released, without dragging), at the same time, we all have to start somewhere. The prize is, that when you master this, you have learned a lot about the Windows API.
Let me know how you get on

thank you !
i am studying to build a program that play chess(or gomoku) over LAN !
i will build it step by step !
there are very much so program !
when you click mouse on coordinate(x,y) on the board,
drought (stone) will paint !
i want also do that !
have you ever done that ?

No, I have never build a program that play chess(or gomoku) over LAN !.
However, I see that you are taking on a very complex task. If I where you, I would break the task up into a number of DLL's
Seeing that you want to play some sort of game over a network, you will need somewhere where the score is kept, i.e. a server for the purpose of the game.(This need not be the Network Server). The way I would write this would be, Game server Software, which keps track of the various games being played, and which would need no other interface than something to keep track of players and scores, and Client software, which monitors the Game moves, and communicates same with the Game server. The game Server in this case would be the final arbitor on the legality, or otherwise, of any moves.In this scheme of things, you need to think first of exchange protocols for this type of information, implementation of game rules, etc, etc.
I would be inclined at the development stage at least, to implement the clients as a console program, i.e. a Chess Move is implemented by a client by typing something like "E2->E4!, and getting back an error message like: "Err 4087: Sorry, The Piece on Field E2 is a Knight, For a Knight the move E2->E4 is Illegal". After you have this Up,Going and Debugged, you can write some beautiful graphics to simulate the game, using essentially the same messaging service to the server.
Hope this is Usefull,
