COM_InvokeDeep(res, dotted-path, arg1, arg2, arg3, arg4, arg5, arg6, arg7, arg8)
(COM Standard Library required)

The COM Standard Library allows us to drill deeply into COM objects. The function below may make that a bit easier for you to use. It parses the "dotted-path" of a COM object (using COM_Invoke to obtain the appropriate pointer to each parent, where objects in a hierarchy are separated by "."). In this example,

pBody2 := COM_InvokeDeep(pweb, "document.frames[1].document.body")

pBody2 returns a pointer to the body portion of the HTML document located in the second frame of the loaded web page, where pweb is a pointer to the parent IID_IHTMLWindow2.

COM_InvokeDeep can make both method calls - for example, document.getElementsByTagName[span] - and element[item] calls - for example, document.childNodes[1]

For the last loop (the element after the last period), one can pass up to 8 additional arguments to the COM_Invoke command (Note: one can pass up to 10 arguments to a COM object with COM_Invoke, but COM_InvokeDeep will consume up to two of those arguments).

Rules for use:

a) If there's a period in an element's name, don't use that name. Instead, refer to it by its element ordinal. So, for example, one will occasionally find frames in web pages that are named like the following: this.isanoddly.named.frame . Since COM_InvokeDeep (obviously) parses on the periods, returned pointers will be invalid. Instead, identify the frame by its ordinal: document.frames[0] (for first frame in the document)

b) Don't use parentheses () inside the "dotted-path" - use square brackets [] instead.

c) Don't put quotes (single or double) inside the brackets when passing a parameter to a COM object's method:

bad: document.getElementsByTagName["span"] or document.getElementsByTagName['span']
good: document.getElementsByTagName[span]

Sean's COM_Invoke runs the guts of this function. COM_InvokeDeep was developed by lots of folks in the AHK community in this thread (wOxxOm, daonlyfreez, Lexikos, me). Hope it's helpful to you.

Thank you very much for this!

Thanks! But all I did was tweak what you and wOxxOm had already posted. And thankfully, Lexikos has a much better eye for code than I do!

[amokoura]

The standard library should have this included, very nice!

I have modified my copy of this as such
the reason is because when sending a 64 bit integer (Common with account numbers) the value became truncated. very nice by the way

[Sean]

Inspired by this post, I wrote this. If there is no objection, I may combine this into COM_Invoke().

Fabulously shorter and distinct.
Couple things come to mind
I for one and perhaps I am the only one
Use COM_InvokeDeep with excell and account numbers. As Invoke will truncate large numbers it might be good to allow BSTR
consider the following code that works untill we get a large number

This is what i ended up with in the end it was shorter to just do this

Doh i almost tried that but im pretty dumb thanks I Have Tested
I tested out with the alternate if statement and it works perfectly with my large integers
Thank you tons Sean
you are still my hero
