For example, IDisposable is an interface that allows types to support disposability independent of any other inheritance hierarchy in which they want to participate.
The other situation in which defining an interface is appropriate is in creating a common interface that can be supported by several types, including some value types.
Value types cannot inherit from types other than ValueType , but they can implement interfaces, so using an interface is the only option in order to provide a common base type. If you need to mark a class as having a specific characteristic marker , in general, use a custom attribute rather than an interface. For instance you can group Name, Address, etc. Form Buttons — Avoid creating your own navigation and function buttons whenever these buttons are already available in a standard Microsoft Access form.
Try to program the form so that the user can navigate most anywhere — handle illogical navigation with a friendly popup message.
There are a two other sections of our website with programming examples for different aspects of form design and programming:. Form programming help for specific Access form programming issues. For many more form layout examples see our Access database examples. Skip to content Press Enter. User Interface Design Examples Form design is a specific component of user interface design and involves the creation of a system used by people to interact with an object such as a microwave, cell phone, or computer.
Here are a few Microsoft Access form design recommendations and examples for Microsoft Access developers who want to make user-friendly Access interfaces: Interface Control — most novice programmers use a switchboard or nested switchboard for management of navigation within an Access database. Replication of Database.
Faster Access Database. Repair Corrupted Table. Access to QuickBooks. Access Cloud Database. This article mentions the classic approach to developing apps. This includes the creation of apps in addition to working with forms, views, and other elements. Designing a model-driven app requires a range of skills. There are many design tools that enable a model-driven app to be created. At times the app maker plays the role of a database designer, a user experience customizer, and even a process designer.
Model-driven apps are essentially a selection of Dataverse components tables, charts, dashboards that work alongside each other to achieve a business outcome.
These components are delivered in conjunction with the Dataverse security roles to create a user experience that meets the needs of members of different parts of an organization. This means that the same app can be used by colleagues in different departments. In some cases, users will only want to review data and may only have interest in specific areas in order to complete their daily objectives.
The design of tables and table columns is covered under a documentation dedicated to this topic.
