🔌 Connecting to Microsoft Access Database in Visual Studio

This paragraph provides a step-by-step guide on how to establish a connection to a Microsoft Access Database within Visual Basic .NET in Visual Studio. It begins by instructing the user to select Data Sources and then to choose the additional icon to initiate the connection process. The user is then guided to change the data source to a Microsoft Access Database file and select the specific file they wish to connect to. The paragraph also addresses potential issues such as connection failures and suggests installing the Microsoft Access Engine if necessary, followed by restarting Visual Studio. It concludes with instructions on how to use the form designer to drag the DataGridView control from the Data Sources to the winform, and introduces the BindingSource component, which serves as both a layer of indirection for binding controls to data and a strongly typed data source.

Keywords

💡Microsoft Access Database

Microsoft Access Database is a file-based database management system (DBMS) that is part of the Microsoft Office suite. It allows users to store data in a structured format and is often used for smaller applications or personal databases. In the video's context, it is the type of database that the tutorial is focused on connecting to from Visual Basic .NET within Visual Studio.

💡Visual Basic .NET

Visual Basic .NET, often shortened to VB.NET, is a programming language developed by Microsoft for the .NET Framework. It is an object-oriented programming language and is used to create a wide range of applications. In the video, VB.NET is the programming language being used to demonstrate how to connect to a Microsoft Access Database.

💡Visual Studio

Visual Studio is an integrated development environment (IDE) from Microsoft that is used to develop applications for various platforms, including Windows, Android, and iOS. It provides tools for designers and developers to create applications using different programming languages. The video script describes using Visual Studio to connect to a Microsoft Access Database.

💡Data Sources

In the context of software development, Data Sources refer to the origins of the data that an application will use. In the video, the term is used to describe the feature in Visual Studio that allows developers to define and manage the sources of data their applications will interact with, such as a Microsoft Access Database.

💡DataGridView Control

DataGridView is a control in Windows Forms applications that allows for the display and editing of tabular data. It is used to represent data in a grid format, providing functionalities such as sorting, paging, and editing. In the video, the DataGridView control is mentioned as being dragged from the Data Sources to the winform to display data from the database.

💡BindingSource Component

The BindingSource component in .NET is a versatile tool that provides a way to connect a form's controls to a data source. It acts as an intermediary between the data and the UI, simplifying data binding operations. In the video, the BindingSource is automatically created to facilitate the connection between the application and the database.

💡Connection String

A connection string is a sequence of characters that specifies information about how to connect to a specific data source. It includes details such as the provider to use, the location of the data source, and any necessary credentials. In the video, the connection string is automatically added to the app.config file to establish the connection to the Microsoft Access Database.

💡app.config File

The app.config file is an XML file used in .NET applications to store configuration settings. It allows developers to change settings without modifying the application's code. In the video, the app.config file is where the connection string for the Microsoft Access Database is stored after it is automatically added.

💡Microsoft Access Engine

The Microsoft Access Engine, also known as the Microsoft Jet Engine or the Access Database Engine, is a database management system that allows for the manipulation of data in Microsoft Access databases. If the connection to the database fails in the video, installing this engine is suggested as a solution.

💡WinForm

WinForms, short for Windows Forms, is a .NET framework for building Windows desktop applications. It provides a graphical user interface (GUI) for applications. In the video, WinForms is the platform where the DataGridView control is dragged to in order to display data from the Microsoft Access Database.

💡Strongly Typed Data Source

A strongly typed data source is one where the data types of the fields are known at compile time, allowing for type checking and other compile-time benefits. In the video, the BindingSource component can act as a strongly typed data source, which means it provides type safety and compile-time checking for the data it manages.

Welcome to FoxLearn

In this tutorial, I'll show you how to connect to the Microsoft Access Database in Visual Basic .NET

To connect to the Microsoft Access Database in Visual Studio, you can select Data Sources on the left side, then select the additional icon to connect to the database

Next, You need to change your data source to the Microsoft Access Database file, then select the Microsoft Access Database file you want to connect

Finally, you need to check the connection, if the connection fails, you need to install the Microsoft Access Engine

then close and reopen your visual studio to reconnect the Microsoft Access Database.

Open your form designer, then drag the DataGridView control from your Data Sources on the left side to your winform.

As you can see, Visual Studio automatically creates BindingSource to help connect data between your application and database.

The BindingSource component serves two purposes.

First, it provides a layer of indirection when binding the controls on a form to data.

This is accomplished by binding the BindingSource component to your data source,

and then binding the controls on your form to the BindingSource component.

Second, the BindingSource component can act as a strongly typed data source.

Now open the app.config file, then you can see the connection string is automatically added to the configuration file

You can select the control type for each property, then drag the properties you want to display details to your Form.
