Once the Username and Password has been verified from a database or txt file the logon form will close and allow you to continue with app.

Once again, what is the client logging into? An SQL Server, Windows Server, Linux box, what?

I think you thinking too deep, once i type in a username and password they are sent via TCP/IP or other method to the server(PC) were the usernames and passwords are stored if there is a match then the logon form will close.

Actually, you're not thinking deep enough. Are you connecting to a WebService, HTTP site, SQL Server, or are you going to be writing the Authentication Service for the server machine?
Each method has a radically different method of connection and communication. So, YES, it DOES matter!

If I cant explain it this time then forget it. Imagine 2 PCs on a LAN - PC1 has a text file containing a list of usernames and passwords with some sort off server app that reads that text file, PC2 has some sort of client app installed which has 2 text boxes one for Username and one for Password and a login button, when you enter a username and password and click login its send the username and password to PC1’s server app that app then reads the text file to see if the username and password exists the answer is then sent to PC’2 client app and a message box pops up says “User Found” or “User not Found”.

And that application is __________?
Is this server application something you wrote or something someone else wrote and your trying to call it?

Finally! An answer we can use! I asked you a couple of posts ago:
are you going to be writing the Authentication Service
for the server machine?
and you never answered the question. Up until now, you never said if it was a component that some else wrote and your trying to use or if it was a component that you want to write. So, yes, your going to write both the server and the client pieces.
There's a bunch of different ways you can do this. But, what is going to work for you could be complicated by the path to the authentication server.
If your going to go over the Internet, you're undoubtedly going to go through a couple of firewalls, in which case a Web Service would be your best bet to get through those walls.
If your staying inside the company network, you could also run into firewalls that will can block you, especially between cities/sites like you are. Again, a Web Service would work, but .NET Remoting is also a possbility if your network won't prevent you from doing this. .NET Remoting will at least let you pick the ports you want to use, whereas WebServices run over standard HTTP.
Try reading Remoting and XML Web Services in Visual Basic .NET[^] for an introduction to both and see what you think.

You have described IIS on the server side, and any web browser on the client side.

e.g. Server sits in London and the Client sits in Edinburgh, I wont to enter a Username and Password in Edinburgh and the credentials are verified from a database or txt file in London.
That sounded to me like he was describing an ASP.NET application. IIS for the server and a webbrowser for the client.
I think I hit reply on the wrong post.

actually...i'm new to this domain....though it is written in windows form application,cldnt i make it work in web form based application?this is my query?

Nope. It must be completely rewritten to work in a web page. Since the browser environment is very restricted and communication with whatever your monitoring is slow, there's little chance, if any, of this ever happening.

how can we create an executable file.
i.e.,. to run a c file with graphics(exe file) we need BGI file. but consider DAVE game it run without any supporting file, how it is possible....? can anybody help to create my own executable (c graphics exe file )file that run independently with out need of any supporting file...
|

You can ask this question a thousand times. We still don't have any clue what your talking about. BGI file?

Based on the reminder Colin gave me...
You'll have to rewrite the C .EXE. BGI stood for Borland Graphics Interface and supplied the library functions that the application used to draw a user interface on the screen. Since it was written in Borland C, you'll have to rewrite it so you can use Windows for its interface. That way, it won't need the supporting files, they're already built into Windows.
