Noob Question re: Collection Elements

[RoscoeT]

Hello Board,

I just started to code some scripts with Autoit last night for the first time. I am pretty good at scripting in general with lots of PHP experience.

Searched google and the help files and not found what I am looking for so I am asking for help or a pointer to a specific doc.

If I have a function that returns a Collection how can I get information about the valid elements in that collection? Similar to the print_r() function in PHP or maybe the array_keys() function.

For example in the code below from examples I've seen, I know that $oLink.href is a valid "property" for each element in the $oLinks collection. But how could I see what other "property" names are valid? I know that many of the functions that return collections have some documentation. But suppose you needed to test it or had an undcoumented User Defined Function, how could you find this?

$oLinks = _IELinkGetCollection ($oIE)
$iNumLinks = @extended

$GetHandle = WinGetHandle("Windows Internet Explorer")
WinSetState($GetHandle, "", @SW_MAXIMIZE)

For $oLink In $oLinks
; NEED HELP HERE....
NEXT

Much thanks in advance for any tips or help.

I don't know if it helps but you could try something like this.

$oLinks = _IELinkGetCollection ($oIE)
$iNumLinks = @extended
$linkEl=""

$GetHandle = WinGetHandle("Windows Internet Explorer")
WinSetState($GetHandle, "", @SW_MAXIMIZE)

For $oLink In $oLinks
    If IsDeclared($oLink.href) Then $linkEl=$linkEl&"href: "&$oLink.href&@CRLF
    If IsDeclared($oLink.name) Then $linkEl=$linkEl&"name: "&$oLink.name&@CRLF
    ;...and so on
    Msgbox(0, "Elements of Link "&$oLink, $linkEl)
Next

I think what he's asking is how to find all the properties of the members of a collection if it's not documented.

Thanks for the reply,

I guess what I am asking is... If you did not know that $oLink.name was called $oLink.name how would you know to check it with IsDeclared() ?

We know that $oLink has "properties" (unsure of the proper name) called "href" and "name" and various others. But were is that documented? And if its not documented how can you probe $oLInk to get the names of all its properties?

They are called attributes, hope this helps. Edited January 14, 2009 by Das Ami

They are called elements, hope this helps.

Well.. yeah.. but that's not what he's asking. Elements are the HTML stuff... what if other things return collections in autoit. I know in Powershell there are commands to probe for properties and methods of an object. Is there something equivalent in autoit?

(I'm curious now too).

Yes, exactly.

Thanks, can anyone answer this?

Little help, anyone?

What is the page, or an example of what you are trying to search and trying to find? If I understand what you want, you may just have to parse the page.

Hi,

All I am trying to do is figure out how to determine what methods and properties an any object contains.

If I have a function, for example _IELinkGetCollection, that returns a collection of objects how can I know the valid properties and methods of each collection member?

In PHP it's print_r() or array_keys()

In the above example I know, from user examples that an object returned by _IELinkGetCollection() has the property href. But if I did not know that, how could I ever figure that out?

That is just an example for one object. How can I figure it out for any object? Not just that function. This is a general language problem and not specific to one piece of code.

Thanks,

I found one thing that helps for arrays

The _ArrayDisplay() function works pretty well. I would like to see something similar for objects and collections.
