I am developing a project in VC++ regarding mathematics using VC++/MFC. I want to plot "graphs" of various algebraic and trignometric expressions. If you know any article or if you have source code for "exprssion plotting" then please let me know through this forum or e-mail me. I shall be very thankful to you. There are few articles on codeproject that deals with statistical data plotting but not a single that plots the "expressions".

I have had problem with registering COM components on clean winNT (sp 6) systems. Now it seems that the c++ runtime libraries on a clean system are older than on a system with WinNT & visual studio 6 (sp 4). Is there any way (application/source) that can check for MISSING dependencies of a COM component (exe & dll)?
regards,
Brian.

What kind of COM object is it, was it created with ATL? The Depends utility (Platform SDK tools) will tell you what DLL's are being used.

We use "Unicode Release Min Dependency" but still we need to copy dll's like msvcrt.dll to the clean winNT system in order to register/run our (ATL) components. I know I can use visual studio's 'depends' nut that tells me the dependencies of a file and not which dependencies are missing on my system.
What I would really like is a program (or source code) with which I can check if all dependencies are installed on a target system.
regards,
Brian

To reduce our support problems, we are using "Release Min Dependency" or "Release Unicode Min Dependency" for our components. If the component are using MFC too (basically CString & COleDateTime for programmers that can't live whitout it), we change the MFC settings to "Static Library"
Although the components are a bit larger, they are almost standalone.
In our case, this means 15% more code size in our entire system. And a lot less support calls.

You can always write another msvcrt.dll and so, on the instalation directory of your component. Your dll will be loaded instead of the \<win..>\System32

I'm trying to write a program which needs access to the id3v2 tags in some MP3s I have downloaded and compiled id3lib from sourceforge successfully (to a dll).
http://id3lib.sourceforge.net/
I am now trying to write the code in my program.
I have looked at the documentation for the API online:
http://id3lib.sourceforge.net/api/index.html
I have tried copying some of the code snippets from the first page (that is the only help they give you!). I have tried to alter it so that it reads the TIT2 field from a sample mp3 as a test. I renamed one of my MP3s to song.mp3 put it in the directory with the compiled exe and ran the program. It should have printed the title on the screen (it is a simple console program just for testing). It doesn't but I don't know what I am doing wrong.
What I would like to request is some proper sample code, with explanations, for a program which uses id3lib to read the title tag from an mp3 file and prints it to the screen. A helpful addition to make it useful to everyone would be code for writing a new title to the mp3 file.
Please help
Thankyou in advance.

Hi,
I have a snapshot file (.snp) Certain tools are available which read the code and display the formatted contents. Is there any way to convert this into a normal text file, or a doc (ms word) file?? Can i get the source code of the snapshot viewer or get my hands on the syntax of a snapshot file??
Any help would be welcome.
Thanks.
Ankur.

Hi.
I would like to know how an application to block/release access to the network by the IP from the station.
Why do I wannt to do it?
I have a network with 16 win 9x that my clients can access the web. they pay per minute, sou I want develop a program to be installed at each machine that do this:
- my custumers will choose how many time they will be connected,
- they will click on start button and then they will acess;
- 5 minutes before the time expires they will be prompted to renew the connection;
- at the end of the time they must be blocked.
I need some ideas how to do this.
Thanks in advance

This might not be relevant, but I will post anyway...
You could probably do this without coding much if you use Mirosoft ISA server. If you are not familair with ISA server, check out http://www.isaserver.org
What you could do is create an ALLOW or DENY protocol rule for certain IPs or users. You would then schedule these rules so you could enable these rules for certain times only (eg. Now till 15 mins more).
ISA server could be configured from a scripting language, so you could make a script that will help you configure ISA server (calculating of schedules,payments etc..).
Notifications 5 mins before would have to be coded seperately, however, that is the easy part.
If you try this out, let me know!

I have added a 'version' resource to my project, and am using a build auto increment add in. How can I read the current build number from within my program to display it in the about box.
Thank you,

I am trying to find some code which will enable me to determine what domain or workgroup a given host is in.
There is a function available on Win2000 (NetGetJoinInformation), but I am using NT4.
Any ideas?

Hi,
I try to implement an ActiveX that creates a thread (through AfxBeginThread). This thread is calling a custom event. When I try to terminating the thread, it makes an uncaught exception. Even, when I try to communicate from the custom event with the activeX (by testing a property for example), I get a memory problem.
How can I solve these problems ?
thank you very much for your help.

Hi all,
I need to find a way to put scancodes in the keyboardbuffer. I need scancodes because serveral apps on the system only react to scancodes (most of them are accessibility tools like JAWS) On Win2K I'm using SendInput and that works fine but I can't find anything similar on Win9X.
Any thoughts ?

SendInput() works on 98. For 95 try keybd_event().

SendInput works on 98 for VK's but not with scancodes.( Unless I'm overlooking something)

Alright, first, a quick explaination of my problem.
I make a piece of software that the company i work for uses to control logons to a computer. It is a computer rental place, and upon timing out the login screen has to pop up to the top of ANYTHING that could be running and stay there.
I have it running in Windows 9X, and is quite secure. I hide it from Control Alt Del menu right off the bat, and on the login screen i press it to the front with a collection of APIs called many times a second.
But we are considering moving to windows XP. Its task manager can see (and end) my process at any time, regardless of any API i have seen so far. Task manager cant stay in front of the login screen, but when someone logs in (the login screen goes away) they can simply end the task for the software!
Not Good!
So, I've been reading up on how this all works, and I have a couple ideas on how to fix it but no idea how to approach any of them.
#1: Run the program under alternate credentials. This WORKS (access denied trying to end my task), but damit, have to enter the password every time (very bad, many computers). Anyone know how to start a task under alternate credentials and have it start automatically? this would solve the problem, and i think it would be best. Storing the password in a batch file in plain text is NOT an option. some of our users are fairly good with computers.
#2: Run a stub-service that that checks for status of my login program, and starts it again if it disapears. Since the users will be low-access and the service runs under ./SYSTEM, it can't be stoped. so if anyone kills the task they will be greeted with the login screen when it starts back up. This would also work, but i have no idea how services work.
#3: Find an API that lets me once again hide the task completely like 9x. I dont like this at all, but if its the only way it will have to do.
#4: Any other sugestions? 
Can anyone reccommend anything that would help me on this problem? we can keep using 9x for a while, but it would be nice to have XP in order to start pimping it when it hits the streets. That means i have to start working on it now to have it on systems by the 25th of oct.
