Reference with Forms system object, Access knows you are talking about Referring to without using the a system object. Named "Invoice," Access would not be able to tell which one you're are For example, if you have a form and report that are both System objects allow you to refer to an object that may have the same name as an object of aĭifferent type. They are virtual containers that only exist in memory. System objects are similar in that they contain objects, but The Database Container contains each object in yourĭatabase. You click on the desired object type and a list of available It contains all the objects in yourĭatabase. This is the window thatĪppears every time you start Access. A goodĪnalogy is the Access Database Container. This tellsĪccess that you are referring to a form, or a control on a form. Whenever you refer to a form or control, you use the Forms system objectīy placing the word Forms at the beginning of the reference. Reports system object contains all the reports that are currently open. Theįorms system object contains all the forms that are currently open. Access has several pre-defined objects thatĬontain a group of your objects. Although they have big names, they areįairly easy to understand. The next page introduces Events in Microsoft Access.To refer to objects, you need to understand two concepts: System
The VBA Language – Functions, Methods and Examples.The VBA Language – Declaring and Assigning to Variables, Conditional Statements and Comments.VBA Code Example: Ensuring names are in Proper Case.This tutorial will focus on a small subset of features of the VBA language as used in MS Access. There are many tutorials that introduce Basic programming. The “Visual” part of the name was added by Microsoft to reflect the use of the Basic programming language in Microsoft Windows. The VBA language is derived from “Basic” language invented in 1964 that became popular on personal computers in the 1970’s. Visual Basic for Applications (VBA) is the programming language used in the Microsoft Office family of software products such as Excel and Access. The way to accomplish such customization is by adding code using the Visual Basic for Applications programming language. For example, the developer may wish to automatically correct bad data before it is saved in the database, show an alert if a business rule is violated, help the user navigate from one data entry form to another or launch a report with some custom filters. Even with these tools, however, there may be situations where the developer would like to add even more functionality not already provided by the MS Access development tools. Various query builder and wizard tools ease this development process.
Microsoft Access includes a number of features to allow database developers to create data entry forms, reports and queries that can guide users in querying existing data in the database and entering new data.
