Interesting, I always built the report in CR and linked to a stored proc. The in the app I would open to report object, give it the production connection and pass the report to the viewer.
I ended up writing a whole framework around the delivery of CR within an app , I'm sooo glad to have moved to reporting services  .

let say, i've a class that implements icomparable
Private Class clsTransfer
Implements IComparable
now i am defining method CompareTo,
Dim fileAccessTime As Date
Public Function CompareTo(ByVal obj As Object) As Integer Implements System.IComparable.CompareTo
Dim objTemp As FileInfo = DirectCast(obj, FileInfo)
Return (Me.fileAccessTime.CompareTo(objTemp.LastAccessTimeUtc))
End Function
Now i am sorting my arraylist
stablefiles.Sort()
i dont know, how to associate my arraylist object with this object of
CompareTo(ByVal obj As Object)
i know i am missing something, but dont know what.....
am implementing compareto method in the same class where my arraylist is defined.
any help would be appreciated....

Well, you got the right idea, just the wrong interface in your compare class. Thanks for showing us you actually did try to get this to work. You have no idea how rare that is! 
The Sort method takes an instance of a class implementing IComparer, not IComparable.
Usually, you just create a small class that implements the lone Compare method defined by the interface:
Public Class FileInfoDateComparer
Implements IComparer
Public Function Compare(ByVal x As Object, ByVal y As Object) As Integer _
Implements System.Collections.IComparer.Compare
' Notice that Compare takes two Objects, not FileInfo objects. Check
' to see if they are both FileInfo objects first.
If TypeOf x Is FileInfo AndAlso TypeOf y Is FileInfo Then
' If they are, cast the Objects back to FileInfo objects
' so we can use them.
Dim op1 As FileInfo = DirectCast(x, FileInfo)
Dim op2 As FileInfo = DirectCast(y, FileInfo)
Return op1.LastAccessTimeUtc.CompareTo(op2.LastAccessTimeUtc)
Else
' Throw an ArgumentException here because both arguements were not FileInfo objects.
End If
End Function
And to call the sort method using this new IComparer implementation:
stableFiles.Sort(New FileInfoDateComparer)
That's it!

You can write a timer in javascript that does a postback after 10 seconds.
Please try to ask ASP.NET questions in the ASP.NET forum in future.

can i know what use of (system.int32)
and dtproduct do i need to declare the "dt" like
is it do like below...
private btncalculate_click(.....)
dim dtproduct as new stocktableadapter
dtProducts.Columns.Add("Total", typeof(System.Int32))
dtProducts.Columns[index].Expression("unitsinstock * unitpricefield")
thanks for the idea

I'm sorry, but I can't work out what your question is. What on earth is a stocktableadapter ? What do you need to know ?

ops sorry bout that i quite weak.i have create a dataset,inside i create itemtable.inside item table i have 3column name Item_ID,Item_Name,Item_unitprice.
010125 Thumdrive 23.50
i use drag and drop method from datasorce to vb.net.how can i count total amoutn if i choose certain item. like wedoing basic math we use unitprice*quantity=total
quantity i click myself and unitprice is given in datasource.
my datasource name for item is itemdatasource,itemtableadapter,datasetname is ComHdataset.

OK - in that case, if the user enters the quantity themselves, then you can calculate the total when they enter it, either in javascript, or via a postback.

i just know programming,html,and vb.net code ....javascript and postback i never learn b4...because i just start my collegue life..it's good if u teach me more..this my final assigment

I don't want to be harsh, but if this is your final assignment, surely you know how to do some research ? You don't need javascript. Postback just means doing it when the server is called, in VB.NET.

The idea is that an assignment stretches you, and establishes what mark you deserve

We don't do that. We passed our courses by doing our own work and we encourage others to do the same. IF you get stuck on something specific, we'd love to help.

Hi to all,
I am new to programming, i just learned VB.net. I thought about to do a project of accounting for a small shop. Which contain sales, purchases, inventory, etc.
If any one have a idea how to design a accounting software please help me. This will help me to do the project and practice.

Your question is too broad. You need to decide how to design your software, will it be n tiered, will it be a web app, what tools will you use, etc ? Then you can ask specific questions here.
It sounds to me very much like this is too big a project for you now, what do you mean by 'I just learned VB.NET'. How long have you been using it ?

You first need to know the rules for accounting e.g. Double Entry Book Keeping.
You need to know how a Nominal/General Ledger works
You need to know the difference between the Balance Sheet and Profit and Loss layouts and Accounts
You need to know how tax laws opporate in your intended market/country(ies)
That's a small sample of things you will need to know about General Ledgers
Stock Control :-
Different costing methods
Landed costs
Batch and Serial numbers
multi-locations
again the list is endless
I would start on something much simpler as a project.

I want to give limit to the splitter bar in a framset so that user cannot move the splitter bar beyond the limit given.
ex-
I want to give limit such that user can move the bar say about 40 columns towards left.Beyond that he cannot move the bar.
Thank You...

If you're using the SplitContainer control, simply set the Panel2MinWidth (right side panel) property to the width of the SplitContainer minus the 40 pixels you want for the maximum size of Panel1 (left side).
mySplitContainer.Panel2MinSize = mySplitContainer.Width - 40
You'll have to put this code in the Resize event of your SplitContainer if your form is resizable and the SplitContainer is anchored to the sides of the form.

I am getting the exception "Exception has been thrown by the target of an invocation" with the following code:
Imports System.Net.Mail
Public Class SendMail
Sub newreportMail(ByVal ex As String)
Dim SendEmail As New MailMessage()
With SendEmail
.From = New MailAddress("from@from.com")
.To.Add(New MailAddress("to@to.com"))
.Subject = "There is a problem"
.Body = "There has been a problem inserting a record : " + ex
Dim client As SmtpClient = New SmtpClient("1.2.3.4")
client.Credentials = New Net.NetworkCredential("from@from.com", "pass")
client.Send(SendEmail)
End With
End Sub
End Class
It bottoms out after a couple of seconds when it reaches the client.send(sendEmail) line.
Any help would be great.

Looks like you copied an example off the web and didn't bother to change it to use real values. I doubt that 1.2.3.4 is the IP address of a real mail server accessible to your network.
