1406001 - accNavigate fails with error code E_NOTIMPL

Status: RESOLVED DUPLICATE of bug 1405065

(Firefox :: Disability Access, defect)

Description

[Rajesh VR]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36

Steps to reproduce:

I am trying to find the URL from Mozilla window using VC++ project. For doing this, I used accNavigate() API with parameter "NAVRELATION_EMBEDS". But the API fails on Windows 7,8,8.1,10 machines (both 32 bit and 64 bit) with Mozilla Version- 56.0. Error code returned is- "ERROR_ALREADY_EXISTS", means- Cannot create a file when that file already exists". Sample code is given below:

// header files
#include "ISimpleDOMNode.h"
#include "ISimpleDOMText.h"
#include "ISimpleDOMDocument.h"

// GUIDs
const GUID refguid = {0x0c539790, 0x12e4, 0x11cf, 0xb6, 0x61, 0x00, 0xaa, 0x00, 0x4c, 0xd6, 0xd8};
const IID IID_ISimpleDOMNode= {0x1814ceeb,0x49e2,0x407f,0xaf,0x99,0xfa,0x75,0x5a,0x7d,0x26,0x07};
const IID IID_ISimpleDOMText= {0x4e747be5,0x2052,0x4265,0x8a,0xf0,0x8e,0xca,0xd7,0xaa,0xd1,0xc0};
const IID IID_ISimpleDOMDocument= {0x0D68D6D0,0xD93D,0x4d08,0xA3,0x0D,0xF0,0x0D,0xD1,0xF4,0x5B,0x24};

	#define NAVRELATION_EMBEDS 0x1009 
 #endif

							hr = pServProv->QueryService(refguid, IID_ISimpleDOMNode,(void **)&pNode);
							if(SUCCEEDED(hr) && (pNode))
							{
								ISimpleDOMDocument *pDoc = NULL; 
								hr = pNode->QueryInterface(IID_ISimpleDOMDocument, (void **)&pDoc); 
								if(SUCCEEDED(hr) && (pDoc))
								{
									BSTR bstrUrl = NULL;
									hr = pDoc->get_URL(&bstrUrl); 
									if(SUCCEEDED(hr) && (bstrUrl))
									{
										//success
									}
								}
							}
						}
					}
				}
			}
		}
	}
	catch(...)
	{
	}
}





Actual results:

accNavigate() with NAVRELATION_EMBEDS failed in Mozilla firefox version 56.0 on Windows 7,8,8.1,10 machines (both 32 bit and 64 bit).


Expected results:

accNavigate() API call success with NAVRELATION_EMBEDS to find the URL.

Comment 1

[Rajesh VR]

if we are browsing popups then those popup windows are getting success with accNavigate API for MOzilla Firefox 56.0, but normal Firefox windows are failing.

Comment 2

[Rajesh VR]

accNavigate returns error code "E_NOTIMPL", GetLastError returns error code "ERROR_ALREADY_EXISTS"

Rajesh, please stop cc'ing anybody who has ever previously engaged with you, every time you file a new bug.

We receive a lot of bugmail, so every time you do this, you just end up spamming a bunch of people -- some of whom are not even involved with the project anymore.

I understand that you want somebody to pay attention to your bugs, so please file them under the "Core :: Disability Access APIs" component and let our triage process take it from there.

Continued spamming by you is going to earn your bugs *less* attention, not more.

ni? you to ensure that you see this.
