AccProbe: The Accessibility Probe

Overview

32-bit

The Accessibility Probe (AccProbe) is a standalone, Eclipse Rich-Client Product (RCP) application that provides a view of the Microsoft Active Accessibility (MSAA) or IAccessible2 hierarchy of a currently running application or rendered document and of the properties of the accessible objects of that application or document. It can also serve as an event monitor for tracking the events fired by these accessible objects. It is meant to combine the functionality of tools like Microsoft's Inspect32, AccExplore, and AccEvent into one easy-to-use application for accessibility testing and debugging.

Getting Started

Since AccProbe is an Eclipse RCP application, ease of use has been a primary objective. Simply unpack the archive you chose to download above to a directory of your choosing. A top-level accprobe directory will be created for you. Within this directory, run accprobe.exe and you're off! For more detailed instructions and using AccProbe, consult the User's Guide, also found in the accprobe directory.

Note: If you intend to inspect or monitor an IAccessible2-enabled application, you will need to register the IAccessible2Proxy.dll packaged with AccProbe. You do this as follows:

In order to install the IA2 Proxy, you need to run regsvr32 from the command prompt as an administrator. To do this, go to the Start Menu and search for the command prompt menu item. If you are running on Windows 7 systems, you must run regsvr32 with administrator privileges. To do that, place focus on the menu item, open the item's context menu (either via right-click or F-10) and use the context menu to select "Run as Administrator", otherwise, simply activate the menu item.

regsvr32 dllname

where "dllname" is the full path to the IAccessible2Proxy.dll.

For example:

regsvr32 C:/accprobe1.2/accprobe/plugins/org.a11y.utils.accprobe.accservice.win32.ia2_1.2.0/IAccessible2Proxy.dll.

Building AccProbe

There are several steps for building AccProbe, depending upon whether or not you wish to build the requisite DLLs:

  • Extract the source code

    • Create a workspace in your eclipse root parallel to plugins directory
    • In Eclipse, import the following projects into the workspace by File->Import->General->Existing Projects into Workspace
      • org.a11y.utils.accprobe.core
      • org.a11y.utils.accprobe.accservice
      • org.a11y.utils.accprobe.accservice.win32.ia2-fragment
      • org.a11y.utils.accprobe.accservice.win32.msaa-fragment
      • org.a11y.utils.accprobe
      • org.a11y.utils.accprobe-feature

  • Open /org.a11y.utils.accprobe/accprobe.product in product configuration editor and go to Contents tab. Make sure org.eclipse.rcp bundle version matches with the one in your plugins directory. If not, remove org.eclipse.rcp from dependencies and click Add and type org.eclipse.rcp in feature selection dialog and select the appropriate bundle.

  • You will also need the following bundles from the Orbit project for an IDE build:

    • org.apache.commons.beanutils
    • org.apache.commons.collections
    • org.apache.commons.jxpath
    • org.apache.commons.logging

Please check your eclipse plugins directory if these bundles exist before downloading them. Download the latest versions and for org.apache.commons.logging, download the one which is used for logging and not for http manipulation. Right now, the latest version for org.apache.commons.logging is 1.04. Download the bundles, drop them into your plugins directory, and restart the workbench.

  • build the AccProbe product:
    1. Select File>Export... and choose Plug-inDevelopment>Eclipse Product
    2. Click Next
    3. Select /org.a11y.utils.accprobe/accprobe.product for the Configuration or Browse to it
    4. Type accprobe as the root directory and check the synchronize checkbox
    5. Select either an archive or directory to which to export the product and provide the remaining requisite information
    6. Click Finish
  • build the IAccessible2Proxy.dll (optional)
  • build the MSAA- and IAccessible2-specific dlls for AccProbe (optional)
