Error Returning Form Name - Need Help !!!

hispeed_mike · August 17, 2011

Hi All,

I have various scripts that automate setup of different network devices via their web interface. Scripted alot of them and cam across a brother printer I need to configure that does not have a form name in the html just an action.Here is my code:

#include <IE.au3> 
#include <inet.au3>

$ip = "10.10.10.100"
$siteid = "Test"
$currentip = "10.10.10.9"
$printname = "Printer"


__HS2170W ($ip, $siteid, $currentip, $printname)

Func __HS2170W($ip, $siteid, $currentip, $printname)
    
        $url = "http://10.10.10.9/bio/general.html?interface=1"

        
        $nav = _IECreate ($url, 0, 1, 0, 1)
        
        WinWait ("Connect to " & $currentip, "")
        ControlSend ("Connect to " & $currentip, "", "Edit2", "admin")
        ControlSend ("Connect to " & $currentip, "", "Edit3", "access")
        ControlClick ("Connect to " & $currentip, "", "Button2")
        
        #cs
        $oDoc = _IEDocGetObj($nav)
        $oArray = $oDoc.getElementsByTagName ("nodename")
        For $element In $oArray
        If $element.id="nodename" Then _IEFormElementSetValue($element, "Found you")
        Next    
        ;_IENavigate ($nav, "http://192.168.1.1/setup.cgi?next_file=Setup.htm")
        #ce
        
        
        $colForms = _IEFormGetCollection ($nav )

        For $oForm In $colForms
            $oFormElements = _IEFormElementGetCollection ( $oForm )
            For $oFormElement In $oFormElements
                If $oFormElement.id = 'nodename' Then 
                    _IEFormElementSetValue ( $oFormElement, "Found You" )
                EndIf
            
                
            Next
        Next
EndFunc

I am trying to change the Data in the edit box called "nodename"

In my code I have tried 2 ways other than using the _IEFormGetObjByName, which only works if it returns a form name.

Help on this is much appreciated, sorry for the wall of text, Thanks in advance.

Hi. To make it easier to read you should wrap all your code in code tags. Highlight the code in your post and click the "<>" icon and it will insert code tags around the highlighted text. You should be able to edit your post and do this, if you like.

PsaltyDS · August 17, 2011

First, what MrMitchell said about using code tags.

Your existing code does not look for a name or id on the form element, it loops through all forms in the collection and searches for an element called "nodename":

$colForms = _IEFormGetCollection($nav)

For $oForm In $colForms
    $oFormElements = _IEFormElementGetCollection($oForm)
    For $oFormElement In $oFormElements
        If $oFormElement.id = 'nodename' Then
            _IEFormElementSetValue($oFormElement, "Found You")
        EndIf
    Next
Next

The matching element appears to be:

<INPUT TYPE=TEXT SIZE=32 MAXLENGTH=32 NAME=nodename VALUE="BRN001BA9657C41" onKeyDown="checkstring()">

Put _IEErrorHandlerRegister() near the top of your script and run it in SciTE to see the error output in the console. See if that gives you some clues.

What do lines 2547 and 1201 of your HS_NETPRINT_SETUP.au3 script look like? Since you don't do any error checking in your script, probably when line 2547 failed the IE objects used from that point on were invalid.

My script is not that long... And you are right, I am still learning alot of this, error reporting is not included, I don't have a great understanding of wrapping code and returning errors as alot of my coding is just throwing commands to windows etc. Your help is really appreciated. Thanks

OK!, So just to update, after many hours and now baldness I worked out why the error...

Seems that the navigating the following way and making the page complete then started returning the $nav value correctly:

$url = "http://" & $currentip;/bio/general.html?interface=1

        
        $nav = _IECreate ($url, 0, 1, 1, 1)
        _IEnavigate ($nav, "http://" & $currentip & "/bio/general.html?interface=1", 0)

        Sleep (5000)
        $exists = WinExists ("Connect to", "")
        WinWait ("Connect to", "")
        ControlSend ("Connect to", "", "Edit2", "admin")
        ControlSend ("Connect to", "", "Edit3", "access")
        ControlClick ("Connect to", "", "Button2")

                $colForms = _IEFormGetCollection ($nav)
        
        For $oForm In $colForms
            $oFormElements = _IEFormElementGetCollection ( $oForm )
            For $oFormElement In $oFormElements
                If $oFormElement.name = 'nodename' Then 
                    ;_IEFormElementSetValue ( $oFormElement, "Found You", 0)
                    _IEAction($oFormElement, "focus")
                    _IEAction($oFormElement, "selectall")
                    Send ($printname)
                    _IEAction($oFormElement, "unselect")
                    _IEFormSubmit ($oForm, 1)
                EndIf
            Next
        Next

So I navigate to a page that does not rely on and wait for it to complete and the $nav value returns correctly, then navigate to the page that requires login and then I get the collection and all is good in the kingdom again.

Thanks all for your help, I hope this explaination could help others...
