I need a simple Windows XP application written in C# which has a button that begins a 3G/GPRS connection via my modem.
However, I have very little experience in C# and I can not find any material on the internet to get me started in setting up a modem for GPRS or 3G connection using C#...........any clues?

Wait, you need a Windows XP Desktop application or a Web Application? Which is it?
I don't know what GPRS or 3G is but communicating with modems is not "simple".

Sorry for the confusion. I have edited the initial post.
3G/GPRS is the cellular networks that surrounds us and made available from the Mobile operators. A modem in our mobile phones connects to this when e.g going on the internet. When we ring someone then we are simply dialling each other's modem numbers I think(over the GSM network) which is completely different.....
To cut the story short, GPRS and 3G are the same in effect but 3G gives faster data rates.
To go on to this cellular network, a modem is required to dial in to this network (a bit like those of you that is on dial-up internet at home).
When I use my 3G datacard (connected to my laptop) then this is in eefect a 3G modem and I can install some software, run it and I get connected to the 3G network......so I want an example code or pointers on how to write my own code to intialise and setup the modem for connection....

Hi there,
Have you looked at how WMI can be used to connect to the modem. I haven't done this sort of thing before, but wouldn't it be easier if your hardware manufacturer provided a SDK for the modem that you could use ?
The following PDF is the closest thing I could find about WMI and 3G device interaction.

Should, in its manual or online, come with a list of command strings that it handles. I once worked with a company whose software required supporting modems over a strange configuration and we literally had thousands of connection strings depending on the modem manufacturer. A hayes compatible modem should carry the same minimum command set across the board.

Can you help how I can achieve this by using CDO objects or Windows Managment Information API in c#.
Thanks

How can I get to database table data and equalize to IList ?
Actually I want to get data from Data Layer and initialize to dataGridView in the View Layer.

Look in the Database Articles here on CodeProject. Look for "data binding" information and examples.

Hi All,
How can I insert a text into a clob datatype column in oracle through c#.
To my understanding, first we have to insert the data to all the columns expect the clob datatype column, then open the newly inserted row in "for update" and then only we have to write the clob column with the value. please corret me also in this regard. Sample code will be of more useful.
Thanks n Regards,

Hello Everyone,
I am currently developing my Univeristy final project and i got into something that i don't know how to do it but i have some ideas.
I want to develop an application to run as a Kiosk mode because it is important that users cannot do anything else but to use this application but i don't know to kill processes only from the current user and not the system itself. Now i think that by replacing explorer.exe by my application name i get some sort of kiosk mode but not completely. But if i can block upon verification any inputs(mouse or "keyboard" only) and kill all new processes i can get it but here relies my problem.
I think i can do it by looking at the computer system processes and check them one by one but I think they should be a more efficient way to accomplish this plus i don't know if all computers load the same processes.
Would it be possible to do?
Any additional info that you might need please ask and i would gladly answer. So far i can get the list of all processes currently running but nothing more.
Thanks in advance,
Regards
Luis

This is the second time you posted this. Don't start new threads for the same subject.

"run as Kiosk mode" Were you absent the day they covered "Requirements"? That doesn't tell us anything useful.
To solve your problem you should 1) Define Kiosk Mode 2) Create two or more scenarios that depict typical use model for the Kiosk 3) Create Use Cases to cover all uses of the system.
That's just a start, after that you still have plenty of work to do before you get anywhere near something like "Killing Processes".

Sorry about double Posting. I think i just got into the desperate state. I will do my best to avoid doing it in the future.
Kiosk mode in this case would be my application only running and stopping any new process that the user would like to start if it is not a Windows process and it does not provoke windows to be unstable. Now when i refer to Kiosk mode I mean that the user only can the window of my application nothing more and depending on what privilege the user has it cannot start any new application. The privilege verfication would be done with a fingerprint reader and it case it fails i would like to have a keyboard keys combination to unlock the application or simply pressing the mouse for any amount of time.

Now this part i think i don't quite understand it, would you mind telling me what do you mean please?
led mike wrote: That's just a start, after that you still have plenty of work to do before you get anywhere near something like "Killing Processes".
I do know how to kill process, like getting the name of the process and comparing it to the Image name but that would be kind of hard to code in a effienct way.
What i would like to know is if there is any possible way to get all of the System, Network and Local Processes at once and kill all others?
Thanks in advance and once more my apologies for double posting.
Best regards,
Luis

Luis, I don't know what they are teaching you at that university but it's not working very well. Let me see if I can illustrate what I mean.
My solution to your "Kiosk" problem is this. I auto launch my application in full screen mode at system startup. The system uses a touch screen monitor which is the ONLY input source since there is no keyboard or mouse. The system is housed in a container such that none of the ports are accessible.
Since you have not provided any Requirements for your problem I have no reason to believe my solution would not work. I seriously question any CIS courses that lead a student to believe they need to "Kill Processes" before they have any understanding of the Requirements for the project.

I think i need to apologize for my english. I am not a native speaker.
And yes my university lacks a lot, because they have some programming courses but in Ansi C and Assembler.
There is a semester about Java but that's it one semester.
All of the things about this project i had to be learning them during the process of it or by questions like yours. For example I want my application to run only on certain computers under certain users. I found out that by getting the Windows current Identity i could do it just getting the name and the sid of the user so it would be up to me to know which user can run it.
I understand the requirements but it is kind of hard to explain them in English.
Mike you are Genius. I mean it. Basically you described my project easier that i can even think of it.
And let try to provide you the req as i understand them:
OS: *Windows XP or Windows Server
CPU: Pentium III and above
Network Conection: 2 Mbps if the stream contains large images and 56 kbps if it is only strings.
Security: SSL and SSH(yet to be determined)
Privileges: Administrator to run the server and Clients.
Data: Database containing all the info that was gotten from the users.
I try to get info in English because there is more than Spanish and most of the times it is better organized and works better.
Mike sorry if i got you upset but it was not my intention.
Best regards,

No actually I am a novice as a Software Developer and will never be anything else. There are actual Geniuses in the field and I urge you to find out who they are and read their books.
One place to start that will reference many of them would be Ward Cunningham's WikiWikiWeb[^].

Well if you are not a genius you are very close.
Thanks Mike i think this experiece has meant a lot to me because it taught me which things i need to know better before posting!
Thanks for the link i am going to look at it now!

use cases are an English Language description of the work flow from the user perspective, along with error and fail paths.
UC1 Start the Computer and ...
1 Push the power button. - the PC turns on and boots to the windows logon screen.
fail states:
BIOS error: goto UC2 Contact Tech Support
Windows boot error: goto UC2 Contact Tech Support
2 At the windows login screen enter your username and password
fail states:
Login rejected. Repeat UC1 step 2.
Multiple failed logins lock computer: goto UC2 Contact Tech Support

Why would you want to kill processes? Wouldn't you just want to prevent users from starting new ones?
It is quite easy to prevent the task manager (via registry) and Alt-TAB and the Windows keys with a global keyboard hook.
