Data Binding
One of the attractions of the graphical text object is its ability to bind to data and change its text
accordingly. So I would show you how to bind the graphical text object to a database and change
its text.
Create a database.
Start MS Access. Create a new blank database and name it as myGraphicalText.mdb and then save
it in the same folder as your project file.


Under Tables, click the New button.

Click the view button in the toolbar and change it to Datasheet View,

You will now be asked to save the table.

Click Yes and enter “myName” as the table name. Click OK
If you did not create a Primary Key, MS Access will ask you if you want to create it now. Answer
Yes.
Now you are in the DataSheet View. Start giving it some name. I have entered 10 names.

Binding a Window Form to the Database.
From the menu, select Tools, Connect to Database.

Click on the Provider Tab and select the Microsoft Jet 4.0 OLE DB Provider.

If you have been following what I have written, you should see the dialog box as shown below.

Click OK, and OK again to close the Data Link Properties Window. You have now succeeded in
linking the Visual Basic .NET to the database.
If you now look at the Server Explorer window, you should see our database has been connected.
