I'm creating a project using Microsoft Access 2007 & Visual Basic 2008.I have two tables in my database, Staff and Training Attended. The Training Attended records of Staff are displayed in datagridview, residing in a different form from the Staff detailsWhat my program does is, it will display all of the Staff's list of Training Attended in datagridview once I click the button in Staff form. I've succeeded in retrieving the records. using bindingsource.filterThe problem is that I can't insert/update/delete records in the Training Attended datagridview. it keep giving me this error: Update requires a valid UpdateCommand when passed DataRow collection with modified rows.

I have problems with the updating and deleting of records in database. I'm using ObjectDataSource and the GridView to display the results in the database. Below is the codes for the update and delete (in the DAL (data access layer). BTW, I'm doing 3 tier architecture in VB.
'update the records accordingly in the database.
Public Function UpdateBooks(ByVal title As String, ByVal borrowDate As String, ByVal dueDate As String, ByVal NameBorrower As String, ByVal book_id As Integer) As Integer
Dim connectionString As String = My.Settings.dbConnection
[Code] .....
I don't know why, but every time I try to update (by clicking on the update button), every thing is not updated, the page would refresh then the records still remain the same in the GridView. As for delete, when I clicked on the 'delete' button, the record is not deleted, it still remains there.
These are the codes in the (BLL (business logic layer)):
Public Function getUpdateBooks(ByVal title As String, ByVal borrowDate As String, ByVal dueDate As String, ByVal NameBorrower As String, ByVal book_id As Integer) As Integer
Dim ds As Integer = UserDA.UpdateBooks(title, borrowDate, dueDate, NameBorrower, book_id)
Return ds
[Code] .....

I have used this form to add new records on my database(ms access) in my database I have a column name 'ID' which is my primary key 'ID' is set as auto number. Now I am having a trouble on creating my update and delete button it's always saying "cannot be delete/update"
Here's my code on add, update and delete
Public Sub SaveRecord()
Try
Dim dbConn As OleDbConnection
Dim dbInsert As New OleDbCommand
Dim str1, str2, str3, str4, str5, str6, str7, str8, str9 As String
[Code] .....
Note my add is working perfectly fine. I just can find the error on my delete and update. Also I have used this to view it to my datagrid I don't know if its the right thing but it's working fine too.
'declared dbpath globally'
Dim dbPath As String = "Provider=Microsoft.Jet.Oledb.4.0; Data Source=../VG.mdb;Persist Security Info=False"
[Code] .....
Another thing is how to code each textbox and combobox to bind it to my records so that when I click on the datagridview each column will be distributed on each respective textbox.

i have a simple application which can create/update/delete/search records using Access database. If i add a record, save it, then close the application and run it again and search for that record, it appears. However, when i write some code to my application, nothing to do with the search function, and i run the application the record is not found. For example i added a button to clear the textfields, and when i ran the application the records i have added earlier were not found.

I'm trying to get the Update button and my Delete button to work. Please advice me accordingly on what I'm doing wrongly. And as for the delete button, I have little clue of doing it. What I want the Update button to do: Basically I have a datagridview in my form. And the DGV displays all the records I have in my mdb file. The user could edit the records directly at the DGV and when the Update button is clicked, both DGV and database gets updated.

I have a datatable populated from an SQL Server 2008 database table. I created a DataAdapter with a commandbuilder to manage the updating, inserting, and deleting of records. The Updating and Inserting work as expected. However, Delete does not. The code runs through just fine without any errors. The number of records in the datatable after the row is deleted even reflects the deletion. The DataAdapter.Update works fine without any exceptions. But when checking the actual table in the SQL DB the deleted record is still there.Here are the parts of my code that deal with this table.

Currently working on a project to automate the input based on the Summary file (xls format)
1. I want to be able to do the following: update, append, delete and populate the records to the various files based on two distinct fields, column A & F (see attached file).
2. Researched the process, requires knowing VB codes, are you familiar with this language? If so, how can I simplify the process? Please advise.
3. The files will reside on the SPP.

I'm creating an application that adds and deletes records from a microsoft access database. The language I'm using is VB2008. I am importing the database through a wizard. I can add records and delete records, but I cannot delete a newly added record without closing the form first. When i reopen the form, I can delete the record. Here is how I have my database setup:
'Bind user info to the controls.
AUSERDataSet = New BulldogUsersDataSet
AUSERTableAdapter = New BulldogUsersDataSetTableAdapters.UsersTableAdapter
AUSERTableAdapter.Fill(AUSERDataSet.Users)
' Setup the binding source.
AUSERBindingSource = New BindingSource

how to do it, but the tutorial is not applicable on the program that I wish to do. The tutorial tells you to add 4 navigation buttons so that you can navigate the database(first, last, back, and forward). Then an update and delete button. But if this is what I will do, it would take 10 years to navigate the database and update a record. Now, what I want to do is just for the user to input a unique ID and click search button(which I have already done). Then the update would be easier. How can I update or delete a record using this method?

I have a project that I am working on that requires me to delete records from the database if they are atleast 3 years old.I have something like this in DB2 SQL to get the date:
SELECT * FROM tableA
WHERE ADD_DATE < CHAR(CURRENT DATE-3 YEARS)
ADD_DATE is stored as Characters in my system, this is why I am converting I know it is also possible to get the date and format it in VB.net which is the language I am using to call the SQL statements.My question is whether it would be faster/better to get the date and perform the conversion inside the SELECT in SQL or would it be better to get the current date and convert it in VB.net and then use that date in the SQL statement. I'm thinking VB.net would be better because there are thousands of records that must be compared. I should be able to set it up in VB so that it only retrieves the date and converts it once but I am not sure what kind of performance hit each takes from these statements.

But then I get the error that the control chkmap has not been declared. I am confused as to how this needs to be declared, do I set a variable to the FindControl("chkmap") and then set it as variable.checked = true ?
