To retrieve data from MS Access database I was using the following code to create a new Recordset. How can we declare it in VS 2008?
Public rs As New ADODB.Recordset
Set MSHFlexGrid1.DataSource = rs
Are the following codes above possible in VS2008?

I used to work in VB.net and used Dataset's all the time when working with ADO, but now i'm Working in C# and the Research is showing me a lot of Recordsets.
Are they the same thing?
If no what is the difference?
how to negotiate a dataset via:
For Each dRow In quanDS.Tables(0).Rows
'do something to each row
Next
I now need to figure out now to loop through a subset of the records returned in the dataset - here's a VB6 example I need to convert:
strSQL = "select * from tblDQ order by xid, xcode, xDOS"
rsMaster.Open strSQL, conDB, adOpenDynamic, adLockOptimistic

I added a bindingsource and set the datamember to a table (in access) which has two fields. My bindingsource name is M and the field is usersT. how do i get its value?I tried:
dim tmp as string
tmp=M.item("usersT")
but this doesn't work.
I have an application in VB6 that joins 3 tables together to create 1 record set and I am able to use the move next and move previous methods to navigate through the record set.
I am having trouble creating this same scenario in vb.net with a data set. Do I have to create each table individually and then link them together somehow or can I join them all together in a query before I fill the data set?
I have a continious Form which opens and shows records of people with whatever criteria the user had chosen the screen before. When the form opens it checks which button was pressed and then changes the recordsource of the continious form.
When I try to edit the records it says "Recordset not updateable". I have done everything I can think of, I have change the type of recordset from dbopensnapshot to dbopendynaset.

I have a piece of software I am converting to ADO.NET from ADODB. In ADODB I can update a recordset by simply.
Dim rs as ADODB.Recordset
rs = query("select * from tblSomethere where something = something")
rs("something").Value = something.Text
rs.Update()
OR IF I WANTED TO ADD
Dim rs as ADODB.Recordset
rs.AddNew()
rs = query("select * from tblSomethere where something = something")
rs("something").Value = something.Text
rs.Update()
I am confused about to easily accomplish this. I know I can use an insert or update command but it would be much easier to do something like this. NOTE: The query just returns a filled RecordSet, it just executes the command and connection without me having to do it all over the place.
I have a recordset rst, that returns the data i require ok. However i wish to transfer this data into an array, and also count the amount of records, as a counter, i.e. 23/312 records.I have tried the way i have used in the past, not .net, of rst.movelast etc, but this doesn't seem to work.
View 3 RepliesI am starting to design in Visual Studio 2008 and I am designing a web application that connects to a SQL database. In VB6 I could create a record set and read its contents as follows.
SQLCommand = "SELECT * FROM Tablename WHERE field = '" & data & "'"
Recordset.Open SQLCommand, Database, adOpenDynamic
If Recordset.EOF = True Then
MsgBox "Record does not exist!", , "Record does not exist"
End If
Then I would Bind the fields data to, say a text box like this
Textbox.Text=Recordset("Field1")
I am finding dificult to do this in Visual Studio 2008. Does anybody know how to create a recordset in Visual Basic 2008 as described above.I have been reading a lot, watching traing videos, and researching on the Internet and I have not found any source which will explain how to do it.

I am working on a proyect and i got stucked,The thing is i have a form which contains a datagrid, and a group of txtboxesI load information into the datagrid through a recorset called rsservices that uses a db table in informix ( i work with adodb connection and adodb recordsets)and it works fine.Then when you click in a record into the datagrid i want it to display the information of the row selected into the textboxes , there are like 5 textboxes each one shows a different info of the same row.
ex : row = Name, last name, address, gender, id etc
but i failed doing that what I tried was, in the activated event of the form :
If rsservices.State = 1 Then
rsservices.Close()
End If
[code]....
after i do all that and run the program the thing loads the first row into the textboxes but when i try to select another row from the datagrid it does nothing?
I'm developing my first SQL Server database app (for 30+ users) and could REALLY use some advice particularly because the app's design is pretty complex so please bear with the long explanation. My app eventually will display an always (hopefully) up to date list of files (and some related metadata) for a variety of purposes (open file, modify file's metadata, etc). The users deal with (open files, modify metadata, etc) dozens if not hundreds of files everyday so developing an app that making it all super quick and easy would really save company time in our environment over the course of a year.
The list is always enormous so my plan at the moment is to never close the app once it's running.The app will have schemes (TBD) for updating the list (modified data, new files & deleted files).It takes approx 45-60 seconds to load all the data which would make my app unusable if I were to allow the user to close the app.The design gets complicated because the list is a merging of two folder structures that share
some relative folder structures and files. The main list comes from a document management system (DMS) and the secondary list comes from a specific local folder structure (e.g. C drive). As with many DMSs, the user cannot modify documents directly in that system.

How do you do nested recordset loops in ADO.NET? In ADO, you could just open one firehose cursor for the outer loop and a static, client-side, read-only cursor for the inner loop and nest the loops. But you can only open one DataReader at a time and Datasets aren't read-only.
