Dim y, X As Integer
y += 20
X += 30
What are these values supposed to represent? I think you need to initialise them with something meaningful.

Then why are you using them, do you understand what they are for?

I used them y=y+1 and x=x+1 as I think that will print row after row and column after column after column, as I know by little information that I have.
by the way I'm not professional in using VB I'm still beginner.

Yes but you have not initialised them to any starting point before you add the offsets.

And then:
1. g = Me.CreateGraphics() is an expensive operation; why is it inside nested loops?
2. Graphics is one of those classes that offer a Dispose method; so if you create (or order creation) of an instance, you should dispose of it too.
Taken together, create once, dispose once.

Because you care about the environment, and don't want big, expensive objects lingering around, possibly holding unmanaged resources, huge memory blocks, system resources, whatever. If you created it and it has a Dispose, call it when done with it.

In VBA for excel I can lift a table from a website using the QueryTables.Add method.
Here is what I use within an existing excel page...
With ActiveSheet.QueryTables.Add(Connection:= _
"URL;http://www.Website.com/Subdir", Destination:=Range("$A$1"))
.Name = "TableName"
.FieldNames = True
.RowNumbers = False
.FillAdjacentFormulas = False
.PreserveFormatting = True
.RefreshOnFileOpen = False
.BackgroundQuery = True
.RefreshStyle = xlInsertDeleteCells
.SavePassword = False
.SaveData = True
.AdjustColumnWidth = True
.RefreshPeriod = 0
.WebSelectionType = xlAllTables
.WebFormatting = xlWebFormattingNone
.WebPreFormattedTextToColumns = True
.WebConsecutiveDelimitersAsOne = True
.WebSingleBlockTextImport = False
.WebDisableDateRecognition = False
.WebDisableRedirections = False
.Refresh BackgroundQuery:=False
End With
As you can see, this polls the website and then looks for the table on that website that I need to connect to.
However, I would like to do the same thing within a VB.Net application.
What method would I need, and are there any pointers you good people could help me out with?

You can use the MSHTML library. The web page is a html document - so you can use a CreateDocumentFromURL and then read the returned document as a html tree.

I have a database with two tables Customers an loans. Customer table contain customer details like id, name, address etc. Loans table contain details of loans taken by customers like loan id, customer id, loan amount. I want to generate a report showing all customers and their loan amount regardless whether customers took loans or not. I tried to do this but it shows only customers who took loans. But i want to show all customers. How can i do this

That depends on the SQL query you used to get the data. Let's see it. Chances are, you're probably not using a LEFT OUTER JOIN to get all the records on the Customer side of the join.
BTW, this has nothing to do with VB.NET...

thanks..
|
|
|
|
|
..that means that there's a physical file, doesn't it. What's to stop me from opening that file using Acrobat?

Adobe reader is give the permission to SaveAs & print.. but i need to view the pdf file without the option SAVEAS & Print...
|
|
|
|
|
So? I'll simply download CutePDF to print the file.
If the file is on the computer of the user, then the user becomes the owner of that file. You can't prevent the owner from manipulating his/her files.

I'm converting an old VB6 application to VB2010 and I've run across a situation I can't seem to figure out from the books I have and web posts so your help will be appreciated.
The problem is iterating through a recordset assigning values to 20+ fields and then doing an update batch.
So far all I've been able to figure out is to use an OleDBCommand class and ExecuteNonQuery method and create individual UPDATE SQL commands for each of the 20+ fields I'm dealing with. I'm hoping there is a simpler way similar to the old ADO UpdateBatch.
Here's sort of what my old VB6 code looks like:
Set Conn = New ADODB.Connection
Conn.Open strDSNName
Set rs = New ADODB.Recordset
gstrSQL = "SELECT * from Judges;"
Set rs.ActiveConnection = Conn
rs.CursorLocation = adUseClient
rs.CursorType = adOpenStatic
rs.LockType = adLockBatchOptimistic
rs.Open strSQL
Conn.Close
Set Conn = Nothing
rs.MoveFirst
Do Until rs.EOF
rs.Fields("Response3").Value = rs.Fields("Response2").Value
rs.Fields("AssignedCat3").Value = rs.Fields("AssignedCat2").Value
...
20 more lines setting field3 to field2
...
rs.MoveNext
Loop
Set Conn = New ADODB.Connection
Conn.Open strDSNName
rs.ActiveConnection = Conn
rs.UpdateBatch
rs.close
set rs = nothing
conn.close
set conn.close
Thanks
