ADO.NET

Databases in Visual Basic:  I using visual basic community 2015

There are all the informations in these two files attachments to make the project.

In data source: Choose; Microsoft Access database file

Send me the project completely in a Zipfile. Thanks

 

 

Databases and Visual Basic • You can use Microsoft Visual Studio 201X to create new databases,
but Visual Studio is primarily designed for displaying, analyzing, and
manipulating the information in existing databases.
• ADO.NET, first introduced in Microsoft Visual Studio .NET 2002, is still
the standard data model for database programming in Visual Studio.
• ADO.NET has been improved over the years to work with a large
number of data access scenarios, and it has been carefully optimized
for Internet use.
• For example, it uses the same basic method for accessing local, clientserver, and Internet-based data sources, and the internal data format
of ADO.NET is XML. • Fortunately, most of the database applications that programmers created
using Microsoft Visual Basic 2008, 2010 and ADO .NET still function very
well, and the basic techniques for accessing a database are mostly the
same in Visual Basic 2013.
• However, there are two new database technologies in Visual Studio 201X
that will be of considerable use to experienced database programmers.
• These technologies are Language-Integrated Query (LINQ) and the ADO
.NET Entity Framework.
• LINQ is included with Visual Studio 201X and offers the capability to write
object-oriented database queries directly within Visual Basic code. • The ADO .NET Entity Framework introduces a new object model,
powerful new features, and tools that will make database applications
even freer from hard-coded dependencies on a particular data engine
or logical model.
• As database technology and the Internet continue to advance, ADO
.NET will continue to evolve, and Visual Basic programmers should be
well-positioned to benefit. Rows are unique - No duplicates allowed Instant Saving – Almacenamiento al instante https://msdn.microsoft.com/en-us/library/jj943772.aspx Data Source Connection Wizard
• The Data Source Connection Wizard is a feature within the Visual Studio
201X IDE that automatically prepares your Visual Basic program to receive
database information.
• The wizard prompts you for the type of database that you will be
connecting to (a local or remote database, Web service, custom data object
that you have created, or Microsoft SharePoint site), establishes a
connection to the data, and then creates a dataset or data entity within the
program to hold specific database tables and fields.
• The result is that the wizard opens the Data Sources window and fills it
with a visual representation of each database object that you can use in
your program. • The dataset is displayed in a hierarchical
(tree) view in the Data Sources window,
with a root node for each of the objects
that you selected in the wizard.
• Each time you run the wizard to create a
new dataset, a new dataset tree is added
to the Data Sources window, giving you
potential access to a wide range of data
sources and views within a single
program. The Data Sources Window
• The Data Sources window is a useful and timesaving feature of the
Visual. Studio 201X IDE.
• Its purpose is to display a visual representation of the datasets that
have been configured for use within your project, and to help you
bind these datasets to controls on the form.
• Remember that a dataset is just a temporary representation of
database information in your program, and that each dataset contains
only a subset of the tables and fields within your entire database file;
that is, only the items that you selected while using the Data Source
Configuration Wizard.
