Error: hr=0x80020003 - member not found.
Error: hr=0x80004005 - unspecified error.
Error: hr=0x80070057 - The parameter is incorrect.
Error: calling getter for this property: hr=0x80004001 - Not Implemented.
These above error reports are generated while i am inspecting microsoft active accessibility (MSAA) objects. I am using a tool windows sdk having an option to 'inspect objects'. We can gather more details about the error, by using sdk in UIAutomation mode.
MSAA, Microsoft Active Accessibility is an application programming interface for user interface accessibility. This api is mainly used with assistive technology(i.e technology for people with disabilities) to support UI elements of that application. MSAA is also used in automated testing tools and computer based training applications.
MSAA is an COM based api which defines a mechanism for application and operating system to communicate. MSAA communicates assistive products by sending information about element of program to the assistive object. MSAA is also available as add-on for the supported browsers including mozilla and internet explorer. It can be used by testing automated software like QTP and silk test as well.
Lets we see the causes of each error, the error 0x80020003 member not found describes ole automation error. This will happens if you are calling IDispatch:Invoke() with wFlags set only to DISPATCH_METHOD and the dispid which identifies the property. This problem mostly occurs if you prefer microsoft visual c++ to generate class wrappers from the mcrosoft office 95 type libraries. For this you need to modify the .cpp file for any InvokeHelper() call retrieving a property to use DISPATCH_PROPERTGET flag. Other reason might be using wrong IDispatch pointer and dispid.
