Microsoft Active Accessibility MSAA is an Application Programming Interface API for user interface accessibility. MSAA was introduced as a platform add on to Microsoft Windows 9. MSAA is designed to help Assistive Technology AT products interact with standard and custom user interface UI elements of an application or the operating system, as well as to access, identify, and manipulate an applications UI elements. AT products work with MSAA enabled applications in order to provide better access for individuals who have physical or cognitive difficulties, impairments, or disabilities. Some examples of AT products are screen readers for users with limited sight, on screen keyboards for users with limited physical access, or narrators for users with limited hearing. MSAA can also be used for automated testing tools, and computer based training applications. The current and latest specification of MSAA is found in part of Microsoft UI Automation Community Promise Specification. HistoryeditActive Accessibility was initially referred to as OLE Accessibility1 and this heritage is reflected in the naming of its binary components such as oleacc. As part of Microsofts Active. X branding push in March 1. OLE Accessibility was renamed Active. X Accessibility sometimes referred to as AXA and presented as such at the Microsoft Professional Developers Conference in San Francisco, March 1. Later, the Active. X branding was reserved for internet specific technologies, and Active. X Accessibility became Active Accessibility and frequently shortened to MSAA. MSAA was originally made available in April 1. Microsoft Active Accessibility Software Developers Kit SDK version 1. The SDK packaged included documentation, programming libraries, sample source code, and a Re Distributable Kit RDK for accessible technology vendors to include with their products. The RDK included updated operating system components for Microsoft Windows 9. Since Windows 9. 8 and Windows NT 4. Service Pack 4, MSAA has been built into all versions of the Windows platform, and has received periodic upgrades and patches over time. Programmatic exposure for assistive technology applications on Windows has historically been provided through MSAA. However newer applications are now using Microsoft UI Automation UIA, which was introduced in Windows Vista and the. NET Framework 3. 0. Version historyeditThe following Active Accessibility versions have been released 2Version. Description. 1. 0. Original add on release for Windows 9. The RDK was supported only in the English version of the operating system. Included in Windows 9. First revision of MSAA that was made available to both English and international versions of Windows. Additional support added for more languages. Introduced satellite DLL oleaccrc. Later the system components were integrated into Windows NT 4. Service Pack 6 and beyond, Windows 9. Windows 2. 00. 0 and Windows Me. First major revision of MSAA, adding support for Dynamic Annotation and MSAA Text. This version was integrated into Windows XP. Minor revisions have been made to the MSAA framework within subsequent versions of Windows. The 2. 0 version of the RDK was made available to older platforms Windows 9. Me, NT in 2. 00. The framework has become part of the Windows Automation API 3. Windows platform accessibility API set by MSAA and UI Automation UIA. Windows Automation API is included in Windows 7 and available for Windows Vista and XP 2. Motivation and goalseditThe motivating factor behind the development of MSAA was to allow an available and seamless communication mechanism between the underlying operating system or applications and assistive technology products. The programmatic goal of MSAA is to allow Windows controls to expose basic information, such as name, location on screen, or type of control, and state information such as visibility, enabled, or selected. Technical overvieweditMSAA is based on the Component Object Model COM. COM defines a mechanism for applications and operating systems to communicate. Figure 1 shows a high level architecture of MSAA. Applications e. g., word processor are called Servers in MSAA because they provide, or serve, information about their user interfaces UI. Accessibility tools e. Clients in MSAA because they consume and interact with UI information from an application. The system component of the MSAA framework, Oleacc. The code boundary indicates the programmatic boundaries between applications that provide UI accessibility information and accessibility tools that interact with the UI on behalf of users. The boundary can also be a process boundary when MSAA clients have their own process. The UI is represented as a hierarchy of accessible objects changes and actions are represented as Win. Events. Accessible objectseditThe accessible object is the central interface of MSAA, and is represented by an IAccessible COM interface and an integer Child. Id. It allows applications to expose a tree structure that represents the structure of the UI. Each element of this tree exposes a set of properties and methods that allow the corresponding UI element to be manipulated. MSAA clients can access the programmatic UI information through a standard API. Roles, names, values, stateseditMSAA communicates information by sending small chunks of information about elements of a program to the assistive technology object AT. The four critical pieces of information on which the AT relies to help users interact with applications are an elements role, name, value, and state Role Conveys to users via AT what type of object a control is, such as a button or a table. The IAccessible method for this is getacc. Role. Name Provides a label for an element, such as Next on a button that moves users to the next page, or First Name for an edit box. The IAccessible method for this is getacc. Name. Value Provides the value of the specified object such as the value on a slider bar, or the information in an editable text box. Not all objects have a value. The IAccessible method for this is getacc. Value. State Identifies the current condition of the control, such as checked for a checkbox. State advises whether a control can be selected, focused, andor other types of changeable functionality. The IAccessible method for this is getacc. State. Microsoft provides a complete list of controls and their functions. 3Role information is based on the type of UI control with which a developer wants to interact. For example, if a developer is implementing a button that is clickable, the developer would select Pushbutton as the Role to implement. The following table shows an example list of MSAA Roles and their related descriptions. Role. Description. ROLESYSTEMAPPLICATIONThe object represents a main window for an application. ROLESYSTEMBUTTONMENUThe object represents a button that drops down a menu. ROLESYSTEMCARETThe object represents the system caret. ROLESYSTEMDIALOGThe object represents a dialog box or message box. ROLESYSTEMDOCUMENTThe object represents a document window. A document window is always contained within an application window. This role applies only to Multiple Document Interface MDI windows and refers to the object that contains the MDI title bar. ROLESYSTEMGRAPHICThe object represents a picture. ROLESYSTEMLISTThe object represents a list box, allowing the user to select one or more items. ROLESYSTEMMENUBARThe object represents the menu bar positioned beneath the title bar of a window from which menus are selected by the user. ROLESYSTEMPROGRESSBARThe object represents a progress bar, dynamically showing the user the percent complete of an operation in progress. This control takes no user input. ROLESYSTEMPUSHBUTTONThe object represents a push button control. ROLESYSTEMRADIOBUTTONThe object represents an option button, also called a radio button. It is one of a group of mutually exclusive options. All objects sharing a single parent that have this attribute are assumed to be part of single mutually exclusive group. Use ROLESYSTEMGROUPING objects to divide them into separate groups. ROLESYSTEMSCROLLBARThe object represents a vertical or horizontal scroll bar, which is part of the client area or used in a control. ROLESYSTEMTITLEBARThe object represents a title or caption bar for a window. Download Visual Studio 2. Retired documentation from Official Microsoft Download Center.
