Hello,
I want to start working in VB.net but seem to have
trouble in understading how I get to an equivalent of a
recordset as in VB6.
The only examples I find are working with binding, but
that is not what I want to do.
I want to be able to create a recordset and go forward
and backwords through it and us it in while not .EOF
structure as I did befor in VB6.
How is this done in VB.NET. Any axemples out there?

that would be a dataset or a dataview
considering your remark about EOF you can use a dataset like this
dim ds as new dataset
'fill your dataset
dim r as datarow
dim i as integer
for each r in ds.tables(0).ro ws
i += cint(r(0))
next

Hi Wim,
It is not impossible to use a recordset, but strongly advices to do not.
With a dataset you can do the same as with a recordset. It is not so often
given as example, but I think the example I give you bellow works even
better than a recordset. This is an example as addition to Eric, but there
are so much possibilities to handle data, that I don't think there is
someone who knows them all. I want to be able to create a recordset and go forward
and backwords through it and us it in while not .EOF
structure as I did befor in VB6.
Another example than EricJ
dim i as integer = currentrow
for a next
\\\\
if ds.tables(0).ro ws(i) < ds.tables.rowsc ount then
myitem = ds.tables(0).ro ws(i+1)("mydata baseItem")
end if
///
for a previous
if i>0
myitem = ds.tables(o).ro ws(i-1)("mydatabaseI tem")
end if
///
I think the rest you understand.
I hope this helps a little bit?

Hi mate,
i had trouble getting round this, got to accept the idea
of recordsets is replaced with datasets.
Similar to recordsets but improved as yuou can now have a
collection of tables rather than the 1 table.
Have a read on datasets (guess this is the inheritor of
recordsets from vb6)

Hi Wim ,
In addition tho the posts already made. I suggest that you obtain an ADO.NET
book and read through. It's a little tough to start out but you will get
there. Also, for ADO type posts for .NET framework such as this one, you
really need to post to
microsoft.publi c.dotnet.framew ork.adnotnet

Wim,
To further OHM's comments, I find David Sceppa's book "Microsoft ADO.NET -
Core Reference" from MS Press to be an excellent resource for everything
ADO.NET. It is a easy read to learn ADO.NET, plus it is a good desk
reference while working with ADO.NET.
Hope this helps

Hi all,
I recently rewrote a data intensive C++ program in C#.
The C++ program was traversing 3 recordsets that were all
open at the same time. I replaced those 3 recordsets with
3 .NET data readers and found that my C# code takes only
about 35% of the time that the old C++ program took to
execute. I'm amazed at this performance improvement, but
finding it hard to believe. I'm supposed to make a
recommendation based on my test results.

here it is.
The code is shown below. My next step is to build this technique into my

I want to populate an array with values from an ado recordset
(multiple rows)
I use the absolute position of the cursor in the recordset to define
the row of my array to be populated. I have a workaround for lack of
a way to define the ordinal position of a field (incrementing a
counter variable), but it feels so primitive:
