Chapter 18. Designing Data Access Pages > Moving to a New Access Form Model

Moving to a New Access Form Model

Data Access Pages (DAP) are a radical departure from traditional Access database applications. Unlike other Access objects stored in .mdb files, Access stores DAP in Dynamic HTML (DHTML) files with a standard .htm extension. DAP that appear when you click the Database window's Pages shortcut, such as the sample pages installed by Office 2000's setup program, represent links to the corresponding DHTML files. The Enter Details item, for example, is a link to the Enter Details.htm file in your …\Office\Sample folder. DAP uses DHTML Data Binding to ActiveX Data Object (ADO) Recordsets generated from Jet 4.0 and earlier databases. Users view DAP in Internet Explorer (IE) 5.0, so they don't need a copy of Access 2000; nor do you need to purchase the Office 2000 Developer Edition to distribute a runtime version of your DAP. However, DAP users must have an Office 2000 license because most DAP rely on the Office Web Components (OWC) for data presentation.

Access 2000 includes a new designer and control toolbox for DAP. A designer is a design-mode tool that automatically generates code to re-create in run mode the objects whose properties you set in a graphical user interface (GUI). Access 2000's DAP Designer differs greatly from Access's Form Design mode. DAP Designer has its own Page toolbar and a Page Toolbox of DHTML-compliant controls.
