Insert - Update - Delete - Select Statements - MS Access Not Working
Jun 22, 2010
I am trying to do simple insert, update, delete, select statements within VB .NET to access a MS Access database. I have tried all kinds of solutions offered on the web and while the code seems to work, no rows are inserted. Also, I have tried, unsuccessfully, to use the Try/Catch to see if there's an error with no success. I have attached the versions of VB .Net and MS Access I am using: Here's the code:

I've just switched from classic ASP to .net and I always used the following to SELECT, INSERT, UPDATE and DELETE from my MySQL databases:
' Create db connection
Function dbConn()
Set objConn = Server.CreateObject("ADODB.Connection")
objConn.Open "driver=x;Server=x;Port=x;Option=x;Database=x;Uid=x;Pwd=x"
[code]....
And to insert, update or delete I'd use:
Call SQL(1,"DELETE FROM Users WHERE UserID = 1")

I am using this code to Add rows to a SQL database, and it adds the row to the SQL database if column 7 is not null. After it adds the row to the SQL database, it deletes it from the Access Dataset, and updates the Access Database. Sometimes double rows seem to get inserted into the database, so I'm thinking there is an error in my logic somewhere here.
Dim rowcount As Integer = AccessDataSet.AccessTbl.Rows.Count
Dim y As Integer = 0
For x = 0 To rowcount - 1
txtRow = AccessDataSet.AccessTbl(y)
If IsDBNull(txtRow(7)) = False Then

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.

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 a GridView that is tied to an EntityDataSource. Most columns are normal bound columns, but two are itemtemplates. When I attempt a delete on one of the rows I receive the following message:
"A property named 'Building1.building_name' was not found on the entity during an insert, update, or delete operation. Check to ensure that properties specified as binding expressions are available to the data source."
I'm not sure how it is possible that this isn't available, since it displays the element just fine when I'm just viewing - it just throws the error when I attempt deleting a row?

I have created a test application to display data in a datagrid, using the Dataset Wizard per the help. All fine - data is displayed.
I then added insert, delete and update queries by selecting Edit Dataset with Designer, selecting the table and adding a query for each action via the TableAdapter Configuration Wizard. In Advanced Options, all boxes are checked, and on the last screen of the wizard it says it has generated SELECT, INSERT, UPDATE, DELETE statements, table mappings, Fill, Get and update methods. The TableAdapter shows four entries: Fill, GetData(); DeleteQuery; InsertQuery; UpdateQuery. On the DataGridView Tasks page, Adding, Editing and Deleting are checked and the data preview shows data.
When I run the application, I can update, add and delete data, but this is not saved.

I followed an example from a VB 2008 Wrox book on creating, binding and updating a data set but I am having a problem. The code is supposed to automatically generate the update/insert/delete statements for me (according to the book) but when I call the update command, the data is not saved.
Here is my code
Code:
Imports System.Data
Imports System.Data.SqlClient
Public Class FrmAddExpenses
[Code]....
After the form is loaded, I change the EntryDate field (which is a DateTimePicker) and close the form which should save the change but it doesn't work.
