Access form elements on different Frames in VBScri

I have these three frames on a website.

<frame scrolling="AUTO" src="../../vix/thalada/Rangasamy?MokkaKumuta1234567" name="AAN">

<frame scrolling="AUTO" src="../../vix/thalada/Rangasamy?MokkaK****13245678" name="BAN">

<frame scrolling="AUTO" src="../../vix/thalada/Rangasamy?MokkaK****85234175" name="CAN">

This is how it goes:

Set oIE = CreateObject("InternetExplorer.application")

        oIE.Visible = True
        oIE.navigate ("https://ec.rcuwebportal.au.eds.com/cics/r1cb/rm0p00ba?cb246")


     oIE.Document.getElementsByTagName("a").item(0).Click       // This works and it clicks on a image button in the frame named AAN. Fine

Next when I tried to access another text box that is present in the frame named BAN , I got the object not found error. Obviousy, because I'm still the frame AAN , but the element belongs to frame BAN.

Below is the textbox that is present in the frame named BAN.

<input type="text" maxlength="30" size="30" value=" " name="BAFREENAME"></input>

How do I access the form control on this frame? Any ideas? Appreciate your help.

You can access all elements off of the frames by first, iterating through the frames, then referencing their contentWindow.document.

Dim oIE, aHTML, oIFrames, frame, i, obj, ifHTML: i = 1
Set oIE = CreateObject("InternetExplorer.application")
oIE.Visible = True

'This page must be remote...
oIE.navigate ("http://your/website...")
'local websites (file://) will return access denied on IFRAME/Frame Content viewing. 



Do
Loop While oIE.ReadyState < 4 And oIE.Busy

Set aHTML = oIE.document

Set iframes = aHTML.getElementsByTagName("frame")

For Each frame In iframes
    Set inputs = frame.contentwindow.document.getElementsByTagName("input")
    For Each obj In inputs
        If obj.className = "BAFREENAME" Then
            'MsgBox "found BAFREENAME in frame:" & i
        End If
    Next
i = i + 1
Next
'MsgBox "done"
