n-tier is the logical seperation of your code where n is the number of layers. By seperating your code into tiers/layers you are making it potentially more maintainable, more flexable and more scalable.
That all depends on if you do a good job of it or not though :P
Here's an ok, if a bit preachy, article:

You have been here long enough to have read the forum guidelines. The highlights:
1. No text speak.
2. Using words like 'help' 'urgent' or 'asap' are considered rude.
3. Some of your questions are basic and would be answered by using this wonderful thing called Google.

Try looking at www.asp,net and then use the 3 tier architecture tutorial link - it shows you basically step by step.
Hope this helps.

I'm looking after a legacy VB6 app. It connects to windows 2000 advanced server which is domain controller (with active directory), and downloads the organizational units and all the security groups under them and populate tree view control. then when user selects the organizational unit it shows the groups under this unit in a grid. After this when a group is clicked in the grid, it populates the second grid with the users from this group. The problem at production machine is that it populate the second grid with some users, but others are not fetched.
I have installed active directory on one 2k3 server in my development environment. When i execute the program on that machine it fetches all the units, groups and users fine. but when ever i run it from any other machine, which is part of the active directory domain (even logging as administrator user on the client machine) it gives error (Table does not exists). Please help me!

It could be many things. I'd start with AD security and make sure that the request for all the users is actually returning what you think it should be. If not, you've got an AD security problem. After that, make sure the grid is being popoulated correctly from your list, be it adding the users line-by-line or if the grid is bound to the data.

Thanks for reply. It was due to network and nothing else. The client and AD server was using different DNS servers so some times it performed okay and other time it was eratic.
Thanks again.

Hi ,
I would like to know anyway to insert two strings into a row with 2 lines created?
My codes are as below
If NodeName = "subProductPrice" Then
If xmlrder.NodeType = Xml.XmlNodeType.Text Then
SubPrPriceList.Add(xmlrder.Value)
For i = 0 To SubPrPriceList.Count - 1
SubPrPrice = CStr(SubPrPriceList.Item(i))
PriceBrkDownStr &= SubPrPrice
Next
PricePerDay = SvcDate & PriceBrkDownStr
dr("dailyPrice") = PricePerDay
End If
End If
Although both the SvcDate and PriceBrkDownStr are inserted into the same row but they are displayed into one line such as below:
dailyPrice
02/03/2007 03/03/2007 120 230
Any idea how to make the date and price separate into two rows in the same table grid row? thanks =)

Hi, appreciate for ur prompt reply. However, i've tried using this way before but it doesnt work. I've tried using the code below
PricePerDay = SvcDate & System.Environment.NewLine & PriceBrkDownStr
I'm doubt whether is it only work for new line in string and not in table grid?
Cheers,
Alicyn

Hey create a new thread and ask your questions there.
Are you answering to the question asked before.

Do NOT hyjack someone elses thread to ask your own totally unrelated question.
But toanswer your question, YES. If you can see the message box while running your code, the customer will see it also!

Hi,
I'm using MAPISession and MAPIMessage components to access MS Outlook emails but the MAPIMessages1.MsgCount always returns 0 even though I've got 100 read emails. I've got Outlook 2002.
The code I have is as follows:
...
MAPISession1.Username = "Outlook"
MAPIMessage1.DownloadMail = True
MAPISession1.SignOn
MAPIMessages1.SessionID = MAPISession1.SessionID
MAPIMessages1.Fetch
iNumOfMsgs = MAPIMEssages1.MsgCount 'iNumOfMsgs declared as a local var
...
iNumOfMsgs returns 0 when there are 100 read emails
Any help with this is very much appreciated

Hey everyone, I need to write a procedure that will give me a list of all the downloadable files on a webpage.
ie, anything encased in , or <ahref="somefile.exe">something
any help would be great.
Thanks in advance.

Sounds like you need to use regex to parse the page and look for tags that are images or links.

Hi,
this is one way that works (I'm explaining in C# syntax, but that is not really relevant):
open MS Word, type the text you want, use the "Insert Symbol..." menu
to insert special characters (whose Unicode code you dont know by heart;
keep a normal font, but adapt the subset as needed), then copy
everything you want to the clipboard.
Now either paste to the Text property of your label in Visual Designer.
Or paste into the literal part of a statement such as myLabel.Text="...";
(if you do this with non-ASCII characters, Visual will suggest you save the source file
in Unicode format, instead of regular ASCII).
If you happen to know the Unicode codes, you can also insert Unicode escape characters
in string literals (so you can keep an ASCII source file);
in C# they take the form \u#### where # represents a hex digit.
I trust something similar exists in VB.NET too
These Unicode escape sequences however seem unavailable in Visual Designer.

Can you please tell me how to make a customised standalone database software...??? Also simple installation procedure for novice user of computer... Because if we use oracle or sql then it is not easier to deploy for novice user of computer.... So is there any other solution or database which is used for stand alone database application?

Access databases, otherwise know as Jet. They don't need to install anything to use them from your code. Security sucks though.

I have an object that I've created to interface with a file upload and parsing in a webapp. The object basically keeps a string of the filename inside itself and then parses the file into a list at the proper time.
The file is uploaded and then hashed and the hash is presented to the user before "signing". After they sign the file is parsed. If, however, they close the page or don't do anything with it, how can I guarantee the file is deleted from the disk? Would it be best to put a deletion routine in the destructor of the object?

Ask the user to confirm the transaction is done in another web page.

There are no destructors in the .NET CLR. There is a Dispose method you could implement, but it'll get called on every object that implements it, regardless if your transaction is complete or not.
