Moving VB6 Recordset To .Net

Feb 1, 2012

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?

ADODB.Recordset Update To ADO.NET

Apr 20, 2011

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.

DB/Reporting :: Creating A RecordSet?

May 2, 2008

I 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.

Load Recordset Into Textboxes?

Oct 25, 2010

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?

Multithreading And Manipulation Of RecordSet?

Mar 8, 2012

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.

Nested Recordset Loops In ADO.NET?

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.

Reading CSV File In RecordSet?

Jan 26, 2009

I have a csv file. I read that csv in a recordset using the following
recordset = CreateObject("ADODB.Recordset")
recordset.Fields.append("F", 200, 255)
recordset.Fields.append("P", 200, 255)
recordset.open()
recordset.AddNew()
recordset("F") = arrText(0)
recordset("P") = arrText(1)

What I want is to create two other recordsets and put in there from the original recordset (query)
Dim rs = CreateObject("ADODB.recordset")
Dim Sql = "SELECT * FROM [table]"
rs.Open(Sql, csvrecordset)
MsgBox(rs.Recordcount)
rs.Close()
And then again with a different query to the third recordset. I think it can be done this way. . but how can I define [table] in my original recordset?

- Overload Resolution failed because no accessible 'item' accepts this number of arguments.

Unbound ADO Recordset To A Form?

I have an access project.I'm trying to figure out the proper way of using an ADODB.Recordset to control data in a subform.For example, I want the user to be able to make additions, deletions, and updates to a subform datasheet. However, if the user presses "CANCEL" from the main form, then I want the data to be replaced with the old data. Likewise, if the user presses "Save" from the main form, then I want to update the database at that time only. The only way i know to do this will update the database after every row is updated. Can I not use CancelBatch and UpdateBacth?

I am working with a table that contains about 10,000 records of which I need to do additional processing on about 1500.The records I need to process are qualified by the field'Cataloged' = True. The problem I have is the table allows for True, False or Null values (I have no direct control of the table to change from allowing Null) for the field I need to test.I run into errors when the value of the field is Null and need to figure out how to determine its Null state prior to trying to qualify the field as True or False value to prevent the errors.
