Ok so for those who do not understand the code please at the moment don't ask about it. I am stumped on the following:

js code:

---

if (Messenger.MyStatus === STATUS_UNKNOWN) {
   
    Debug.DebuggingWindowVisible = true;
   
    var hWnd = Interop.Call('user32', 'FindWindowExW', Messenger.ContactListWndHandle, 0, 'Main Window Class', '');
    hWnd = Interop.Call('user32', 'FindWindowExW', hWnd, 0, 'DirectUIHWND', '');
     
    var IID_IAccessible = Interop.Allocate(16);
    with (IID_IAccessible) {
        WriteDWORD(0, 0x618736E0);
        WriteWORD(4, 0x3C3D);
        WriteWORD(6, 0x11CF);
        SetAt(8, 0x81);
        SetAt(9, 0xc);
        SetAt(10, 0x0);
        SetAt(11, 0xaa);
        SetAt(12, 0x0);
        SetAt(13, 0x38);
        SetAt(14, 0x9b);
        SetAt(15, 0x71);
    }
     
    var pAccessibleData = Interop.Allocate(4);
    if(Interop.Call('oleacc', 'AccessibleObjectFromWindow', hWnd, 0xFFFFFFFC /* OBJID_CLIENT */, IID_IAccessible, pAccessibleData) === 0) {
        var iAccessible = pAccessibleData.ReadInterfacePtr(0);
        if(iAccessible) {
            var iAccessibleChildren = Interop.Allocate(16*iAccessible.accChildCount);
            var iAccessibleChildrenFound = Interop.Allocate(4);
            if (Interop.Call('oleacc', 'AccessibleChildren', iAccessible, 0, iAccessible.accChildCount, iAccessibleChildren, iAccessibleChildrenFound) === 0){
                for (var i=0; i<iAccessibleChildrenFound.ReadDWORD(0); ++i) {
                    if (iAccessibleChildren.ReadDWORD(i*16) === 0x9 /* VT_DISPATCH */) {
                        var iAccessibleChild = iAccessibleChildren.ReadInterfacePtr(i*16+8);
                        if (iAccessibleChild) {
                            try{
>>>                                Debug.Trace(iAccessible.accName(iAccessibleChild));<<<
                            }catch(e){
                                Debug.Trace('epic fail #5');
                            }
                        } else {
                            Debug.Trace('epic fail #4');
                        }
                    }                   
                    else {
                        Debug.Trace('epic ail #3');
                    }
                }
            }
            else {
                Debug.Trace('epic ail #2');
            }
        }
        else {
            Debug.Trace('epic ail #1');
        }
    }
}

• iAccessibleChild.accName()
  
• Copying the pointer to a new databloc and using ReadInterfacePtr
  
• the list goes on; but I forget all that I have tried.

I think it's WORD, as VARTYPE is type-defined unsigned short.

Interesting... I will give it a shot when I get home...

Just using .accName gets the property fine, the reason the exception is being thrown is that it is of type "unknown".
After many varied attempts at making it work, I have come to the conclusion JScript sucks at this stuff

Strangely enough, if you run it when signed in, all the children have accName type as unknown except for the advertisement area which actually returns a string containing the url of the advertisement. Even though the proper accName of that child should just be "Advertisement", with the url actually being the accName of another child of the Advertisement child, which I don't understand at all.

The only property that seems accessible is accChildCount, all others return type "unknown". Pity because this seems quite fun to play around with if it worked

This works thanks to Patchy!

js code:

---

if (Messenger.MyStatus === STATUS_UNKNOWN) {
   
    Debug.DebuggingWindowVisible = true;
    Debug.ClearDebuggingWindow();
   
    var hWnd = Interop.Call('user32', 'FindWindowExW', Messenger.ContactListWndHandle, 0, 'Main Window Class', '');
    hWnd = Interop.Call('user32', 'FindWindowExW', hWnd, 0, 'DirectUIHWND', '');
     
    var IID_IAccessible = Interop.Allocate(16);
    Interop.Call('ole32', 'IIDFromString', '{618736E0-3C3D-11CF-810C-00AA00389B71}', IID_IAccessible);
     
    var pAccessibleData = Interop.Allocate(4);
    if(Interop.Call('oleacc', 'AccessibleObjectFromWindow', hWnd, 0xFFFFFFFC, IID_IAccessible, pAccessibleData) === 0) {
        var iAccessible = pAccessibleData.ReadInterfacePtr(0);
        if(iAccessible) {
            var iAccessibleChildren = Interop.Allocate(16*iAccessible.accChildCount);
            var iAccessibleChildrenFound = Interop.Allocate(4);
            if (Interop.Call('oleacc', 'AccessibleChildren', iAccessible, 0, iAccessible.accChildCount, iAccessibleChildren, iAccessibleChildrenFound) === 0){
            Debug.Trace('Child Count: '+iAccessibleChildrenFound.ReadDWORD(0));
                for (var i=0; i<iAccessibleChildrenFound.ReadDWORD(0); ++i) {
                    if (iAccessibleChildren.ReadDWORD(i*16) === 0x9) {
                        var iAccessibleChild = iAccessibleChildren.ReadInterfacePtr(i*16+8);
                        if (iAccessibleChild) {
                            try{
                                if (iAccessibleChild.accName(0).match ( /E-mail+/)) {
                                    iAccessibleChild.accValue(0) = 'test@test.com';
                                }
                                if (iAccessibleChild.accName(0).match ( /Status+/)) {
                                    //Doesn't work not sure why...
                                    //iAccessibleChild.accValue(0) = 'Busy';
                                }
                               
                                Debug.Trace(iAccessibleChild.accName(0)+': '+iAccessibleChild.accValue(0));
                            }catch(e){
                                //Most likely the password edit box as you cannot access it...
                                Debug.Trace(e.number + ' /\\ ' + e.description);
                            }
                        }
                    }
                }
            }
        }
    }
}

Well that's an annoying simple way of doing it after all the crap I tried Now to clean up this mess you have created so it is actually useful!

Starting with the IID stuff which can just be done much simpler like so:

JScript code:

---

Interop.Call('ole32', 'IIDFromString', '{618736E0-3C3D-11CF-810C-00AA00389B71}', IID_IAccessible);
