When I am generating report using following code from reportviewer my reportviewer showing the following message.
'A data instance has not been supplied for the data source 'Dataset1_customers'.
Can any one solve the problem?

Imports System
Imports System.Data.SqlClient
Public Class Form1
Dim con As New SqlConnection
Dim str As String
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim da As SqlDataAdapter
Dim ds As New DataSet
str = "Integrated Security=SSPI; User Id=sa;Initial Catalog=Northwind; Data Source = suman"
con.ConnectionString = str
con.Open()
str = "select * from customers"
da = New SqlDataAdapter(str, con)
da.Fill(ds, "customers")
ds.DataSetName = "customers"
RV.ProcessingMode = Microsoft.Reporting.WinForms.ProcessingMode.Local
RV.LocalReport.ReportPath = "C:\Documents and Settings\Administrator\My Documents\Visual Studio 2005\WindowsApplication4\WindowsApplication4\Report1.rdlc"
RV.LocalReport.DataSources.Clear()
RV.LocalReport.DataSources.Add(New Microsoft.Reporting.WinForms.ReportDataSource("customers", ds.Tables(0)))

hi,
in place of statement
RV.LocalReport.DataSources.Add(New Microsoft.Reporting.WinForms.ReportDataSource("customers", ds.Tables(0)))
use following statement
RV.LocalReport.DataSources.Add(New Microsoft.Reporting.WinForms.ReportDataSource("Dataset1_customers", ds.Tables(0)))
hope this helps

Hi,
How is authentication and authorisation through forms achieved in VB.NET? Are the membership classes available like in ASP.NET? If not, are there other resources available to facilitate role management or is it a manual process to manage users of Windows applications?
The application I'm developing is fairly standard, it's a CRM application which requires different levels of users, i.e. administrators, general users, super users etc. In ASP.NET I would have used the membership classes to handle this, however, I'm not sure whether these are available in VB.NET (I am new to VB.NET winforms BTW).
Thanks in advance for any responses.

I am using the following script to echo all members except 'Administrator'
in 'Administrators' group :
strComputer = "XYZCOMPUTER"
Set objGroup = GetObject("WinNT://" & strComputer & "/Administrators")
For Each objUser In objGroup.Members
If objUser.Name <> "Administrator" Then
Wscript.Echo objUser.Name
End If
Next
In a list of Administrators (In XP, accessible through Right click 'My
Computer' -> Manage -> Local Users and Groups -> Groups ->
Administrators (double click)), I've few entries like :
Administrator
user1
user2
xyzdom\user3
user3
user4
The above script echoes user3 twice.
I don't want the script to echo 'user3' for the entry xyzdom\user3.
How could the condition be specified/modified in the script ?
Thanks in advance.

Hi all,
I am trying to write a bit of code in VB.NET (2008) that will look inside a class and find all the public members, e.g.
Public Class User
public Name as string
public Dob as date
public Department as integer
(etc)
End Class
Is there a way for a subroutine to accept an instance of the class as an object, and query it for all these public items. I would search with google, but I dont know what to look for 
Any help, or pointers would be much appreciated!

Anyone got a version of that in English?
Tough reading, but I am sure it is what I need to get my head around to do what I want.
Thanks.

I am fairly new VB.NET but I believe that the Reflection class can achieve this. Somebody please correct me if I'm wrong, but inthe mean time you could try Google'in Reflection.

I'd say the best way to learn how one works is to study the source code of a good one. The best .NET one I know of is YetAnotherForum[^]. It's C# instead of VB but the logic behind it shouldn't be difficult to follow.
As probably a simpler example and as an article, you might want to see this[^]. That's an article describing the discussion board used on CodeProject.

How do I achieve this... say I have an array of bytes in my Java application.
Raises a HTTP connection to a server page say, Enroll.aspx.
I am doing a HTTP POST. I've got the data, but it's wrong somehow.
I think it's messed up the encoding or something.
Can someone advise on how to make this work? How would such a data structure be transmitted without modification?

Does it have to be a HTTP post? I think a better option would be an XML webservice.

I have no idea what you're talking about. I'd say if you're aware of it, you probably should consider learning it.

In many other projects I've seen textboxes, say, where the very long string has been truncated with three dots added to show that it has been trimed - (This is a very long ...). I assumed this was a feature of .NET. It doesn't seem to be, though. Has anyone got any suggestions as to the best way of doing this?

It is - check out the AutoEllipsis property of the control.

Hello,
VS 2008
I am developing phone application. Which will have a dial pad and a display.
In the display the customer wants to have details of (call duration, number being called, status when call is connected and disconnected).
Number being called should be in the top left, Status button left, call duration button right.
I am just wondering what is the best method to go about this.
I was thinking of making a new control and inherit from the text box class. And this textbox will contain the 3 text boxes I need to display the different details. That way they can be aligned correctly in the display.
Any other suggestions or ideas would be most helpfull,
Thanks,

How about using List View Control?? That way you can display all three/four information in one line!
- Stop thinking in terms of limitations and start thinking in terms of possibilities -

Hello,
Thanks for the reply.
The customer doesn't want to display in one line.
Any other ideas about a text box control?
Thanks,
