Forms can be customized by writing programming code to respond to form and <a href="#" class="glossary" onclick="AppendPopup(this,'xddatavalidation')" onkeypress="AppendPopup(this,'xddatavalidation')">data validation</a> events, to access and manipulate a form's underlying XML document, to implement custom data submission and merges, and to implement access to external data sources. Customizing a form can also involve altering one of the <a href="#" class="glossary" onclick="AppendPopup(this,'xdformfiles')" onkeypress="AppendPopup(this,'xdformfiles')">form files</a> to suit a specific requirement.</p><p>It is important to understand a few key concepts that are involved in programming an InfoPath form. These concepts include the InfoPath programming components, programmatic and declarative programming, the InfoPath programming languages, and the InfoPath programming environment.</p><p><a href="#" class="DropDown" onclick="Outline2()" onkeypress="Outline2()"><img border="0" src="blueup.gif" alt="Show">InfoPath programming components</a></p><div id="ExpCol" class="collapsed" border="0"><p>InfoPath programmability involves customizing an InfoPath form by altering its form files or by writing scripting code to create custom functions using the InfoPath object model. The main components of an InfoPath form that can involve programmatic interaction are listed in the following table.</p><table><tr><th>Component</th><th>Description</th></tr><tr><td>Object model</td><td>A robust, hierarchical type library composed of collections, objects, properties, methods, and events that give form developers programmatic control over various aspects of the InfoPath editing environment and access to a form's underlying XML document.</td></tr><tr><td>Data validation</td><td>A combination of <a href="#" class="glossary" onclick="AppendPopup(this,'OfXmlSchemas')" onkeypress="AppendPopup(this,'OfXmlSchemas')">XML Schemas</a>, expressions, and scripting code used to validate and constrain the data that users are allowed to enter in a form.</td></tr><tr><td>Event handling</td><td>A set of <a href="#" class="glossary" onclick="AppendPopup(this,'xdeventhandler')" onkeypress="AppendPopup(this,'xdeventhandler')">event handlers</a> that respond to changes to a form's underlying XML document, respond to view switching, implement custom form submission, or respond to the loading of the form's underlying XML document.</td></tr><tr><td>User interface</td><td>A set of customizable user interface components that includes menus, toolbars, buttons, command bars, and a task pane.</td></tr><tr><td>Editing controls</td><td>A set of InfoPath-specific controls used to manage and interact with the form's underlying XML document that includes collections, optional items, text lists, and fields.</td></tr><tr><td>Error handling</td><td>A combination of event handlers, object model calls, and <a href="#" class="glossary" onclick="AppendPopup(this,'xdformdefinitionfilexsf')" onkeypress="AppendPopup(this,'xdformdefinitionfilexsf')">form definition (.xsf) file</a> entries that are used to handle errors in an InfoPath form.</td></tr><tr><td>Security</td><td>A set of security levels that restrict access to the InfoPath object model and system resources.</td></tr><tr><td>Data submission</td><td>A set of predefined functions that can be used to implement custom posting and submission functionality for an InfoPath form.</td></tr><tr><td>Business logic</td><td>A set of custom scripting files that contain programming code used to implement specific editing behavior, data validation, event handlers, and control of data flow. Business logic can also include accessing of external <a href="#" class="glossary" onclick="AppendPopup(this,'ofcomponentobjectmodelcom')" onkeypress="AppendPopup(this,'ofcomponentobjectmodelcom')">Component Object Model (COM)</a> components.</td></tr><tr><td>Form integration</td><td>Integration of other Microsoft Office applications such as Microsoft Excel or Microsoft Outlook. Integration may also involve the use of back-end servers such as Microsoft SQL Server, Microsoft Windows SharePoint Services, or XML Web services.</td></tr></table></div><p><a href="#" class="DropDown" onclick="Outline2()" onkeypress="Outline2()"><img border="0" src="blueup.gif" alt="Show">Programmatic and declarative development</a></p><div id="ExpCol" class="collapsed" border="0"><p>When you alter the InfoPath form files, you customize the form declaratively<nbsp />— that is, you open the form files in some type of standard text editor and manually change the elements, attributes, and values of the files.
