Dataadapter with dataset - OLEDB Data Source
The OleDbDataAdapter serves as a crucial intermediary, facilitating seamless communication between the Dataset and the Data Source through the utilization of the OleDbConnection Object. The OleDbConnection Object does not possess any inherent knowledge regarding the data it retrieves. Similarly, the Dataset is unaware of the specific Data Source from which the data originates. Thus, it is the responsibility of the OleDbDataAdapter to effectively manage the communication and coordination between these two distinct entities.
One of the primary functionalities of the OleDbDataAdapter is to populate Data Tables within a Dataset. This is accomplished by utilizing the Fill method provided by the OleDbDataAdapter. By invoking the Fill method, we can effortlessly retrieve data from the Data Source using the OleDbConnection object and populate the acquired data into the appropriate Data Tables within the Dataset.
To illustrate this process, consider the following source code snippet, which demonstrates a simple program utilizing the OleDbDataAdapter to retrieve data from a Data Source. The program employs the OleDbConnection object to establish a connection with the Data Source and utilizes the Fill method to populate the retrieved data into the relevant Data Tables within the Dataset.Full Source VB.NET
