As VB programmers, we tend to think of our application as consisting of a number of forms. The word dialog is often used to describe one of the common dialogs provided by Microsoft.
However, from a user's point of view, our application is just like any other one. Some of the windows used by the application are primary windows that display or control some data; often, a well-designed application will have only one of these. Other windows are dialogs that are displayed to get some data from the user or to control some process.
The Windows User Interface (UI)
describes two types of dialogs, modal and modeless.
