I am having no issues reading from an Access database, just when I am trying to add a record to the database I am getting no results. I am using a 64bit computer, and am aware about running in the x86 solution platform. I am getting the result that it hassuccessfully added. But nothing is showing up in Access
Private Sub voteBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles voteBtn.Click

I'm at another wall in my project. I've been trying to get it to add a new record to a table but I got a message that said "Object reference not set to an instance of an object" but I have no clue where the error is popping up. I am also unsure of whether the coding for adding a record will actually work on not.Here is the code for the form with the bits subs that I'm sure aren't the problem removed (as they have no relevance to adding a record);
Imports System Imports System.Data Imports System.Data.OleDb Public Class NewStock
We're trying to work out some code for saving from a textbox to a database field without using DataGridViiew. We have it working using the automated controls that Visual Studio gives us, but if we have a form with text boxes, can we make it so that, on a button click, it dumps that stuff into a field in a table?
I'm getting an error doing this. Here is my Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click Dim con As New OleDb.OleDbConnection Dim dbProvider As String Dim dbSource As String Dim dsgames As New DataSet [Code] ..... The error appears on the very final line, "dagames.Update(dsgames, "games"). This is the error: "Operation must use an updateable query."
im trying to add data to an ms access table that I have created elsewhere in the app. The code I am using is below but I keep getting an error message (Update requires a valid InsertCommand when passed DataRow collection with new rows.)
con.Open() sql = "SELECT * FROM attachment" da = New OleDb.OleDbDataAdapter(sql, con) da.Fill(ds, "Attachment")
I just want to add a value from a textbox/variable and save it as a new record in a MS Access Database after a button click.
I've set up the database, set up the tables required.
From what I gather, I need to first link declare 'Imports System.Data' outside all the code. And also define a variable as a connection (Dim con As New OleDb.OleDbConnection) then access the database with "con.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source = PathName").
Having trouble adding a new record to an access table. I have the table called ITEM. Want to create a new row and then add a record to the table. Can't seem to open to connect to the table... Its bugging me :L
I've been having a problem adding a record to an Access database using datasets and da.update etc. I'm trying to create a simple program that displays the records of a database table in a series of text boxes. I've managed to get my next and previous buttons working correctly and my update button works correctly too. The problem occurs when I try to add a new record. I keep getting a "Syntax error in INSERT INTO statement" whenever I click my add button.
I have two tables Products and Categories with a many to many relationship. I am trying to copy the categories linked to one product (OriginalProduct) to another product (newProduct). The problem is when I execute the SaveChanges() method, I not only get the records in my linking table, but it also creates another copy of the categories in the categories table. I've tried this in many ways but here are the last couple that I've attempted:
' Copy Product/Categories For Each oneProdCategory In OriginalProduct.Categories Dim relatedCategory = _productContext.GetObjectByKey(New EntityKey ("ProductInfoEntities.Categories", "RecordId", oneProdCategory.RecordId))
Why my delete button wasn't work. it say "InvalidOperationException was unhandled' at m_daDataAdapter.Update(m_dtContact). What that means?[font=Arial Black]

I have programmed in VB before (vbexpress 2008) and used "formname.show()" to open and show new forms that I wished to open. I try the exact same code in vb10express(beta) and get errors! Did the code change? I cannot find any information on it if it did... or is it possibly a "betatest error" that needs to be addressed?
I programmed in VB6 but with VB2008 I have trouble with this:I have a table called Clientes (Clients). One of the fields is called Provincia (State), but this is a numeric field wich references to a Provincias table.So, when I show the Clientes from, the Provincias field must use a combobox with the province name instead of a textbox with a number.
I have a database linked to my VB.NET project using the data source wizard. I've created a log in form using a table in access that has the details required to log in.

I am having problems adding a new row to a datagridview control in my form. I have a simple formwith a textbox, a button and a datagridview. When the user types in an item number and clicks on the button, the system will populate the datagridview with the relevant data from the database.All these works fine but, when the user tries to add another record, the first record added to the datagridview is cleared off the datagridview before the next record is displayed. I would like the datagridview to add all the records without clearing the screen. The datagridview is not bounded to the database.
