I think I need the username password because everytime I try to send an email, I get an authentication error.
But then again, if, as you say, I don't need a username and password, THAT might be the problem.
I shall make an attempt with both, and make note of any errors that occur. If they do, I'll post the error messages here.
Thanks for the help man!

as far as why I think that the server requires authentication...
when I try to send an email, I get an error. It reads:
"5.7.3 Client does not have permission to submit mail to this server."
I think the message is a pretty dead giveaway...

does the client have an exchange mailstore associated with it ?
try this:
go to START->RUN type in cmd
from the command shell type in TELNET severIPaddress 110
110 is the POP3 protocol port number.
Type in USER username press enter
Type in PASS password press enter
Telnet should response with user successfully logged in. If it doesnt then you know that the user doesnt have access to the exchange server.
I dont have Exchange server installed on my test box yet. But when I did build my automated email client which sent emails out to my exchange server, i never had to supply a username/password to my email client software.

g'day mate,
sorry my earlier post does not make any sense. Tomorrow when I get to work I will install Exchange server on my test server and run that snippet of code i posted earlier. Just one thing did you actually run that snippet of code I post couple days ago ?
Will update tomorrow with my progress regarding username/password sending email.
sorry for not being too useful.

It's cool... No worries here.
The code that you have is what I am using at the moment.
I'll check out telnet and see what happens with that.
**EDIT**
So i checked out the telnet trick there. It sorta kinda worked. I could get to the login section where I typed USER and PASS. No matter the combination that I used, I could not get logged in. It may (or may not) be because I don't know where to put in the domain info. I tried with the user, but to no avail.
I *DO* know that the user name and password have access to the exchange server because I have Outlook set up, and it is using the exact same credentials as the user that I was using. And Outlook works just fine.

hi again,
today I installed Exchange 2003 on my test server running windows server 2003. The same test server was my domain controller. I just did a default installation of Exchange and Active Directory. I didnt change any security settings etc because I have zero idea about active directory security maintenance.
I ran a test network with my test server being the exchange and domain controller. In this network I ran another Win XP client machine which was not part of my test domain. I wrote the SMTP code I gave you a few days ago as win app and ran it on this Win XP client machine and I was not prompted for any username or passwords.
This would leads me to believe that your configuration of active directory and exchange must be running some high security configuration which needs the user to be authenticated before any email can be sent out or received.
There are 3 solutions you can try:
1) The first solution is that the machine you are using to run the SMTP code I gave before needs to logon to the domain and authenticate the user. The user needs to be part of the active directory. Then run the email sending application you wrote. Maybe check with whoever setup the exchange server on its user authentication requirements.
2) You use an alternative .NET based SMTP class. I gave you the reference Lumisoft.dll. Go to this website and download this dll library:
http://www.lumisoft.ee/lsWWW/Download/Downloads/Net/LumiSoft.Net.zip
Create a new .NET windows application and use the Lumisoft dll to create an email sending application. You will need to use the LumiSoft.Net.SMTP.Client.SMTP_Client namespace. There is a chm helpfile which describes how to use the dll. I dont have the time right to write you a code snippet but read through the helpfile and there are code fragments to get you started.
If you get stuck go to the author's webpage he has a forums section and put a post there. The author is a very nice guy and he has an article on codeproject regarding the lumisoft.dll.
3) In the code I had provided earlier ensure that you used the defaultcredentials property take a look below:
System.Net.Mail.SmtpClient smtpServer = new System.Net.Mail.SmtpClient("192.168.0.1");
smtpServer.UseDefaultCredentials = true;
What this does is that whoever is logged on to the machine that is executing this code their credentials will be used to authenticate against the SMTP server. You have to makesure that the username and password are actually validated against active directory being used by your exchange server.
Let me know how you go and I will see if I can write some code using Lumisoft.
Good luck.

You give me much to work with... 
Sadly, that first one isn't exactly an easy option to explore. What with the ungodly number of miles of red tape and all...
So that third one looks a little promissing. I was taking a look at a few other things that might help with that. I think it was called User Impersonation.
Do you know of this?
From what I've read, I *THINK* it may help me in this task.
But before I overcomplicate things, I first want to try your third option there, and if that doesn't work, I'll go for #2.
Once again, thanks for the help. I'll post the results when I get some...

well you are in a tough situation so looks like you get more and more work 
I have heard of user impersonation. I believe that the DefaultCredentials aspect of the SMTP class would do the trick, which is the third option.
I'll see if I can work out how to sent restricted access on my Exchange server so that the user needs to be validated before they can send any emails out via SMTP. Then give option 3 a go myself. The key thing is that whichever user is logging onto the machine needs to be authenticated against AD successfully. Only then that particular user will be granted access to use Exchange and only then your little application will work. Provided you have enabled the DefaultCredentials feature in your code.
With impersonation you can do the samething. YOu need to define security attributes around the method which needs user impersonation.
Have you fun

If you ever need to use special characters, which the IDE will tell you what they are, you need to use the escape character \. So you write and double quote ", use \".

I programming with C# and I want to print an image. Please help me !

Hello,
The "System.Drawing.Printing" namespace will help you.
There you find the Installed printers : System.Drawing.Printing.PrinterSettings.InstalledPrinters
Then you need following classes for the setting:
PrinterSettings (Here you can set the printer name)
PrintDocument (There is the Print() method)
In your PrintDocument instance you have to handle the PrintPage event, which will be raised after you call "Print()".
The PrintPageEventArgs e has a Member Graphics, where you can draw your bitmap into:
e.Graphics.DrawImage(yourbitmapinstance,0,0);
P.S.: Instances of PrinterSettings and PrintDocument have to be Dispose(), to not waste memory!
Hope it helps!
All the best,
Martin

Hello Judah,
This web already I saw. I already know that there are many components in Internet that do that, but are of payment. I need to know like doing it without using an existing library. The web that you have put is of a trial component. Long ago that I'm looking for it.
In any case thanks.

Hi !
I am creating a software that will save the present state of all the applications running on the desktop (WinXP).
Can anyone point out the method to extract the filenames from the handles (or otherwise) of the files that are being accessed by processes and programs ?
For example : If I have opened xyz.docx in MS Word 2007 then I want to find out the name of the file ("xyz.docx") and its complete path through some mean which could be either :
1. Reading or extracting information from the Word 2007 process handle.
2. Through another non- handle based general method.
Kindly help !
Regards,
Aditya

Currently im learning to use the application development of VisualStudio 2005
i have created a basic local database with two forms, customer and order, with the obvious fields, CustomerID, Firstname etc in the Customer form. In the Order form i have OrderID(PK), CustomerID, Products, etc etc. I have setup my dataset and i have drag from the dataset to the form. i can input data in the form when running and it carrys the primary key through from Customer table to Order table and works fine. yet when i use the save button from the navigation bar that was automatically added to the form it does not save this data once i input test values.
Ive tried multiple tutorial videos from Microsoft C# express and VS help and i have even gone as far as using Visual Stuidos inbuilt 'howto' online help...which is useless to me
From this i would like to add two buttons which when clicked will save(update) and delete data to BOTH the tables.
Help with what code i need to put behind these two buttons would be much appreiciated.
Thanks 
Cass
If any other information about my setup is needed just ask.
