with webbrowser component:
Add a reference to microsoft html object library
add a webbrowser component
Paste this code:


Dim ieDoc As HTMLDocument
Private Sub Form_Load()
wb1.Navigate "www.angelfire.com/realm/vb-shared/index.html"
End Sub


Private Sub wb1_DocumentComplete(ByVal pDisp As Object, URL As Variant)
If (pDisp Is wb1.object) Then
    Dim i As Integer
    Dim tbl As Object
    Dim cell As IHTMLElement
    Set ieDoc = wb1.Document
    For i = 1 To ieDoc.frames.length
        For Each tbl In ieDoc.body.All
            If tbl.tagName = "TABLE" Then
                For Each cell In tbl.cells
                    Debug.Print cell.innerText
                Next
            End If
        Next tbl
   
    Next i
End If
End Sub

To use with Internet explorer itself you need to add a reference to microsoft internet control instead of webbrowser control.

Dim ieDoc As HTMLDocument
dim withevents IE as InternetExplorer

Private Sub Form_Load()
set IE = new InternetExplorer
with ie
     .Navigate "www.angelfire.com/realm/vb-shared/index.html"
     .visible =true
end with
End Sub


Private Sub IE_DocumentComplete(ByVal pDisp As Object, URL As Variant)
If (pDisp Is IE) Then
    Dim i As Integer
    Dim tbl As Object
    Dim cell As IHTMLElement
    Set IEdoc = IE.Document
    For i = 1 To ieDoc.frames.length
        For Each tbl In ieDoc.body.All
            If tbl.tagName = "TABLE" Then
                For Each cell In tbl.cells
                    Debug.Print cell.innerText
                Next
            End If
        Next tbl
   
    Next i
End If
End Sub

Hey, Richie:

I tried something like this and it worked:


    If webX.Document.frames.length > 0 Then
        Dim hDoc As HTMLDocument, i As Integer
        Set hDoc = webX.Document
        For i = 0 To hDoc.frames.length - 1
            For Each Tbl In hDoc.frames(i).Document.All
                  'do something
            next Tbl
        next i
    endif

Two questions:
If your page hasn't frames, it doesn't read any table.
Where do you use that code? I suposse in Document_complete, right?
Your code is a little compact than mine. I did mine in a rush.
Be carefull, that code would enumerate .all tags, if you don't check whitch tag is....
Cheers

Hey Richie,

First of all, I want to thank you for all of the help that you have given in the past.  I say, you must be paid to answer EE Q's all day!  I'd like that job!  

1)  "If your page hasn't frames, it doesn't read any table..."
I am gathering info from a number of sites, one of which uses a frameset.  So I use this code on that particular page.  

2)  I first use a WebBrowser control and navigate to a web site.  I then pass the  WebBrowser control (webX) to the code that you see above.  Then I loop thru the frames and tables, inspecting each table for the presence of a value in a particular cell.  Once that value is found, then I extract the values from the target table!  I don't even bother with tags, as some pages that I use don't have tags on the tables!

Richie_SimonettiIT OperationsCommented:
Yeah, thank you! I remember you.
Regarding HTMLTable (and other html elements). Sometimes, all collections doesn't manage very well for each ... loops for some reason that i hadn't time to know why.
I had to face a time ago with that problem, all col returns all tags and sometimes the loop asign a value to tbl (as in this example) which is not a table at all and the code is messed up!

It's amazing how creative you can get with the use of error handlers!
