What are the methods for connecting VB to access database?
Oct 16, 2023 pm 02:54 PM
Vb connection access database method: 1. Use ADO connection, first import the System.Data.OleDb module, then define a connection string, then create an OleDbConnection object and use the Open() method to open the connection; 2. To use DAO connection, first import the Microsoft.Jet.OLEDB module, then define a connection string, then create a JetConnection object and use the Open() method to open the connection.
In VB (Visual Basic), there are two ways to connect to an Access database:
1. Use ADO (ActiveX Data Objects) connection:
Imports??System.Data.OleDbDim??connectionString??As??String??=??"Provider=Microsoft.Jet.OLEDB.4.0;Data??Source=C:\myDatabase.mdb"???Dim??connection??As??New??OleDbConnection(connectionString)??? connection.Open()
Here, we first import the System.Data.OleDb module, then define a connection string (including the path and file name of the database file), then create an OleDbConnection object and use Open() Method opens the connection.
2. Use DAO (Data Access Objects) to connect:
Imports??Microsoft.Jet.OLEDBDim??connectionString??As??String??=??"Provider=Microsoft.Jet.OLEDB.4.0;Data??Source=C:\myDatabase.mdb"???Dim??connection??As??New??JetConnection(connectionString)??? connection.Open()
Here, we first import the Microsoft.Jet.OLEDB module, and then define a connection string (including the path and file of the database file name), then create a JetConnection object and open the connection using the Open() method.
In actual applications, you can choose to use ADO or DAO to connect to the Access database according to your needs. However, it should be noted that DAO may be more stable than ADO in some scenarios. After connecting to the database, you can use various methods provided by ADO or DAO to perform SQL queries and manipulate data.
