![]() I will use some of these to fill up a list box with the records of our RecordSet. The RecordSet object allows us to move in it by using the methods MoveFirst, MoveNext, MovePrevious, MoveLast (among others). Now that we have opened a table (referred to as RecordSet from now on) we want to access the records in it. It gives you a RecordSet that you can add, delete and modify records in. The Dynaset mode is the mode I use mostly. VB's online help file explains the different modes and what they are for. ![]() You can open a RecordSet in several modes. What happened there? Well, I declared a RecordSet object and used the Database object's OpenRecordSet method to open a table of type Dynaset. Set rsMyRS = dbMyDB.OpenRecordSet("MyTableö, dbOpenDynaset) To declare such an object and to open the table, do this: Visual Basic uses an object called RecordSet to hold your table. But in this "Visual Basic - Database Primer" I will only show you how to open a single table. You're not limited to open a single table sometimes you have two or more tables that are related to each other and linked together with foreign keys, and there are ways to handle this to. What you need to do is open a table in the database. You should really specify the complete path to the db, but if your current directory is the directory where the database is situated, this will work. ![]() Set dbMyDB = OpenDatabase("MyDatabase.mdb") To open a simple Access database named ôMyDatabase.mdb", do this: This gives you a variable/object that can hold a reference to your database. You need to declare a variable to hold your database in order to do this. The first thing you must do in your application is to open a database where your tables are stored. This text requires some knowledge of the Visual Basic programming language and you should be familiar with the Visual Basic IDE (Integrated Development Environment). We will at the end of this lesson have made a simple, yet functional, phone book application. I will only use an Access Database (*.mdb) in my examples, since this is the most used DBMS (DataBase Management System) for smaller applications made in Visual Basic. You will get familiar with opening a database and retrieving/adding/deleting/updating records from tables. What I will teach you to use in this text is DAO (Data Access Objects). I will not even mention the Data control further in this text, since it is so easy to use and too limited to be interesting for a professional developer. There are many ways to work with databases in Visual Basic, and I would think you have at least glanced at the Data control. I almost never make a program without using a database for data storage. This is what I think you should learn next you will find many applications for this knowledge. ![]() What I think is the most compelling thing about Visual Basic is itÆs easy way of accessing and modifying databases. You have come to understand the basic of Visual Basic and you want to move on.
