Connect to Microsoft Access database and Fill DataGridView
As in the previous post , much sensilla and with very little code, we will see how to connect in visual basic. net with a database file in Microsoft Access and then retrieve data from one of the boards DataGridView filled with them.
The first thing to do is import two namespaces as show below:
Imports System.Data Imports System.Data.OleDb
For this example we will use a form with a button (Button1) and a DataGridView (DataGridView1). In the click event of button1 a copy the following code and the name of the database. Mdb and the table name in the statement SELECT ) so that everything works fine.
Dim cnn As New OleDbConnection ("Provider = Microsoft.Jet.OLEDB.4.0; Data Source = C: \ myBaseAccess.mdb; User Id = admin, Password =;") Dim da As New OleDbDataAdapter ("SELECT * FROM Products", cnn) Dim ds As New DataSet da.Fill (ds) DataGridView1.DataSource = ds.Tables (0)
Well, actually not much to explain ... you create a connection (CNN), then a DataAdapter (da) having as parameter the statement to retrieve data ( SELECT ) and the connection to use (cnn). If you want to select only certain records need to add a condition WHERE the select statement.
In the following lines we will leave some brief definitions in case any of you were needed and to learn more about the different options for creating a connection to Microsoft Access I leave also the following link: http://www.connectionstrings.com/access
DataAdapter
Represents a set of SQL commands and a database connection that are used to fill the DataSet and update the data source.
DataAdapter serves as a bridge between the DataSet and a data source for retrieving and storing data. To act as a bridge, DataAdapter Fill method assigns, modifying the data of DataSet to match the data source, and assigns the Update method, which modifies the data in the data source to coincide with those of DataSet.
DataSet
Represents a memory cache of data. It is a fundamental component of the ADO.NET architecture. DataSet consists of a collection of DataTable objects.
DataTable
Represents a data table in memory.
DataTable is a central object of the ADO.NET library. Among the objects that use DataTable and DataView DataSet included.
When accessing DataTable objects, you must keep in mind that these are case-sensitive conditionally. For example, if one DataTable is named "mydatatable" and other "Mydatatable", the string that is used to search one of the tables are considered case-sensitive. However, if there is "mydatatable" but no "Mydatatable" is considered the search string is not case sensitive. A DataSet can contain two DataTable objects that have the same TableName property value and different values for the Namespace property.

[...] To write the example of connecting to SQL Server and Microsoft Access Connection I realized that even though these are the two types most used databases when [...]
because the truth was very helpful. because I needed a code as simple as possible because I had trouble loading a table from access to a datagrid and all the codes I tried this was the only thing that brought me across the table and with so little code
With truth and blessings

I served a lot thanks! watching it even if I wanted to know how filtering by country, to find a particular record.
Greetings .. very good your article and your page ... I was going to ask how to clean the DataGridView1 every time you click a button to query and view data, but I think the fix, if not right, but at least I worked . The only thing I did was add "ds.Clear ()"
So:
ds.Clear ()
da.Fill (ds)
DataGridView1.DataSource = ds.Tables (0)
Now as I make a TextBox where typing a name billboard showing only the results found in the DataGrid ..
A. - To clean: ok what you do, you could also do DataGridView1.DataSource = Nothing
2. - To display only the data that match the textBox the procedure is the same, the only thing that changes is the SELECT statement that performs the search. For example: "select * from Employees WHERE Name LIKE '%" & TextBox1.Text & "%'"

I have worked with Visual Studio 6 and I'm trying to work with Visual Studio 2008. I did what the manual says to display data from a table in a DataGridView, without success. DataGridView is displayed, but not the data. In the load event of the form are automatically placed lines of code to populate the data, but apparently that does not work. Anyone know if this is a known problem?
Hello Oscar:
It has many secrets ... DataGridView control needs you indicate in the datasource property which is the table containing the data or may have a databindingsource. I recommend you look at these two articles and I'm sure you'll be able to achieve.

Thank you very much.
Guys I answer myself.
insert:
As New OleDbDataAdapter Dim daagregar ("insert into orders (IDPLATO, Quantity, IDMesa, CustomerID, Date) values ('" & TxtCodigo.Text & "', '" & TxtCantidad.Text & "', '" & TxtMesa.Text & "', '0', '8 ')", cnx)
daagregar.Fill (dsPedidos)
hol such I would like to know as I do to insert data into a datagridview but if the value exists and send a message that already exists because GREETINGS
Grateful for the code ...
Is there any way of recovering the data in the gridview and put them in a PDF file??.

Hello, I connect with an Access 2007 DB from C #. NET here all right, but I have a table that has three fields with dates and I want to give an output format and I have two options:
1) After completing the DataGridView to format each field containing date
2) Do it with a SELECT statement:
SELECT TOP 20 *, Format ([buy_date], "Long Date") & "" & Format ([buy_date], 'Short Time') AS [buy_date] FROM ORDER BY id DESC testing
The problem with this view is that it places the [buy_date] from position 4 to 2 and I have to write more code to order and that's what I do not want
Regards

hi all need help with discharge of a record to the data link connection and going well but then for the high I get this is the code
connection:
Formclientes_Load Private Sub (ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim connection As OleDbConnection
connection = New OleDbConnection ("Provider = Microsoft.Jet.OLEDB.4.0; data source = C: \ proyectovb.net \ tesis.mdb")
As DataSet Dim dsCustomers
As String Dim consultaclientes
consultaclientes = "select clientes.dni, clientes.apellido from customers"
As New OleDbDataAdapter Dim daclientes (consultaclientes, connection)
dsCustomers = New DataSet ()
daclientes.Fill (dsCustomers, "clients")
Dgvclientes.DataSource = dsclientes.Tables ("clients")
Add button:
As DataTable Dim TABLACLIENTES = New DataTable ("Customers")
As DataRow Dim REGISTROCLIENTES = TABLACLIENTES.NewRow
REGISTROCLIENTES ("dni") = Me.TextBox1.Text
REGISTROCLIENTES ("NAME") = Me.TextBox2.Text
TABLACLIENTES.Rows.Add (REGISTROCLIENTES)
I use to discharge as do I make a new high but first check if the record already exists
I expect some response from some solidarity through
Big Beast!!!
I had already burned up the tabs
I'm using vb6 and vb recent change to 2010
THANKS!!
SEEMS TO ME THIS IS NOT CODE FOR VB 2010
PORFAVOT can teach anybody know
LEARN QUISIEA URGENTLY!
Excellent contribution. Congratulations poured me a lot. I iniciandome in the world of VB.NET. Although I have enough programming, but you always need examples so when you change the programming language. Regards
I saw nothing open about this, but I want to add form data to a database in access and I can not, if someone could help would appreciate
regards
I was very helpful, thanks!
Komo litter kapo, look I have a question, I'm programming with VB. Net 2008 for quite not use it, and good was picking up. I commented.
I did a module where my definition of coneccionn sentensia, and the data adapter and data set, I made the connection in the jump from a mistake but I n my Coneccion.open, looks like I did and tell me if you can help me ..
MODULE
Imports System.Data
Imports System.Data.OleDb
Module Module1
As New OleDbConnection Public ConecZion ("Provider = Microsoft.Jet.OLEDB.4.0; DataSource = C: \ Documents and Settings \ USER \ My Documents \ Pr Testear.mdb")
As New OleDbDataAdapter Public DataAdap ("select * from [Club XXXX] order by NrodeSocio" ConecZion)
Dataset As New DataSet Public
End Module
[B] AND HERE FROM THE [/ B]
FrmFormwork_Load Private Sub (ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ConecZion.Open ()
DataSet.Clear ()
DataAdap.Fill (Dataset, "miTestearDt")
Dataset.Tables ("miTestearDt"). DefaultView.Sort = "NrodeSocio ASC"
ConecZion.Close ()
End Sub
THIS ERROR AND STRIP ME
Could not find installable ISAM.
porq can be? : S..
I hope to embrace response
Thanks for the help the problem is fixed commenters creating an instance of the DataSet that was declared at the beginning for example my variable is called a record then it would be: Dim record = New DataSet () and voila!
