Hello Experts,
i have a problem with my current project. I hope someone of you can give me some help or hints. Let me first describe the project and then the problem.
The program is a test generator for the embedded systems. The application is a framework that performs some housekeeping things like loading databases, etc. All extensions are made by means of plug-ins which are simply DLLs. Every plug-in can have a gui which is displayed in the framework. Basically the framework displays dialog resources stored in the DLLs.
Now here my problem: One of the plug-ins displays a grid where some cells contain dynamically created buttons. When the grid is loaded it creates for every cell that needs a button an instance of a class derived from CButton. My problem is that i get no events from these buttons. If i click on them they even do not change their apperance (they are not pressed in).
When i developed the button class i checked it in a simple dialog based application and everything worked well but in my current application it does not work  .
Any ideas?
Thanks!
Patrick

Can you use spy++ to see if the grid gets any windows message, when you click on it, for instance ?
~RaGE();

Hello Rage,
thanks for your reply. I do not see any messages sent by the buttons. In the working program (dialog based) i see WM_COMMAND messages.
Regards
Patrick

Hi all,
I want to upgrade from VC6 to VS 2003 or 2005, but need to be able to keep my existing projects in VC6 until they are fully working in the new compiler. Are there any issues with installing both systems together or are they best kept well apart?

Hi,
I have all 3 installed on my system, without any problems

I am using VC6 and VS2001 together, no problems.
Except that, if you try to run your VC6 code on a later system, you will be told that it needs to be altered first. If you allow this to happen and open your old programs on you new IDE, I don't know of any way to go back.
So until you choose to move your code over, it is certainly best to keep the projects apart. I had a fairly large project on VC6 and decided to use VS2001 on it. This was fine for a long time, but a week ago I finally ran into some problem that I could not resolve, and decided that the time had come to properly update my project. So I made sure I had an extra backup, renamed the old folder, created a new project in VS2001, and transferred all the source files over.
This tooke a morning, what with having to change a lot of include paths due to VS2001 using s different layout from VC6 for its files. But it was certainly worth it in the end to move to a newer system. Cleared out a lot of junk files in the process.
But I still use VC6. For one thing, there is inforamtion in its help system that you will not find in VS2001 and, I assume, in all later versions. And from time to time I come across code written for VC6 which I would not want modified.
I would upgrade to VS2005 if I could find a supplier. Whether I would then still use VS2001, I don't know. Buying it was a bit of a mistake, being a new IDE at the time. More mature code tends to have bugs / deficiencies that are less glaring.

But you can - with a slight overhead of work, maintain the old as well as the new Project files and Solutions.
This way, your codebase can be used from both IDEs.
The work-overhead comes from activly *not* using new features of the VC7.1-compiler, keeping the VC6.0 comments for the class wizard intact, and from maintainig two sets of incompatible compiler output directories.

Well, I suppose that this is a possibility. But unless there is a good reason to be able to use both IDEs on the one solution / project, I prefer to make a clean change over. (And what if I had both IDEs open at the same time on the same project? Chaos...)

Hi Guys,I badly need a C++ source code for jobshop scheduling (6 jobs on one machine)using the genetic algorithm where the objective is to minimise the overall setup time between the Jobs.my e-mail adress is mpavis4@yahoo.co.uk. Pls help!!!!

Hey thanks for redirecting me to Illinois Genetic Algorithms Laboratory.
It looks like i have new material to study. really have to pull nights.
|

No problem. I've used (hand-coded) GAs for a couple of applications but not for jobshop. There are a number of free libraries around, IlliGaL is a good starting point. Writing a simple jobshop GA shouldn't be very hard.
Good Luck!

Hi
It looks like you are a student and have to submit assignment. right!
well it looks like you too have to pull nights now to complete assignments. right

Hi guys
i want to know how to draw a chessboard on a form. any idea?
|
|

I think the best way to do that is to make your own custom control (derived from CWnd). Look at the section in the MFC for miscellaneous controls to get some examples of custom controls.

well thanks for reply.
i am trying to create sudoku solver and needs some grid kind of control.
Opps! it looks like i have to pull nights again.right!

That's funny because some weeks ago I started to make a Sudoku game and I made already a small control for the grid. There is not a lot of things in it and it is still a little bit uggly but if you are interested, I can send you the code (not now because it is at home). But I stopped the project because I couldn't find a good way to hide some specific cells in order to have a specific solution grid (generating the grid was ok).
But don't expect a control with excellent graphics

i am happy to know you too are intrested in sudoku. well i'll be glad to have a look at your grid control. pl. send it to this email add(vikramsharma @ gawab.com)
thanks again for help

I love that game, and play it every chance I get. I even suggested to our local newspaper to start running it. The editor said I was the first to suggest it, which is a polite way of saying, "Snce the interest is so low, probably not." About a month or so later, I saw the first puzzle! Whether I had anything to do with it or not, I'll never truly know.

maintain a matrix to draw the Chess board
i see! nice idea. can you let me know how to drow this way.
I guess :
-create 2D array.
-fill it
-create rect, do maths, then create rectangles.
but is this ok for sudoku like game where i have to insert numbers in the rectangles.
pl. let me know.
thanks for idea and reply

Look at the link Rage submitted you. It seems that this control is far more better and complete than the one I made. I suggest that you download the source code and have a look at it.
