[Help]VB6 + Webbrowser + Iframes + Different Domains]
1 - The Situation:
I'm Using "Visual Basic 6"
I'm Using "Webbrowser Control"
I'm Using "Microsoft HTML Object Library"
====================================================
2 - What I Want:
*Acees objects (buttons, links, etc) on a IFRAME
*Get all links for example, click in links, etc...
This is easy... but...
===================================================
3- THE PROBLEM:
The page A is in www.abc.com
The page B is in www.xyz.com
The Page A contains one iframe to page B
I Can't acess elements in Iframes with diferrent domains using normal methods.
====================================================
4 - Example:
PAGE A.html (www.abc.com/PageA.html) ==>
<html>
<body>
THIS IS THE PAGE A!<Br>
PAGE A contains one Iframe to PAGE B!<br>
<Iframe id="PageB" name="PageB" src="http://www.xyz.com/PageB.html">
</body>
</html>
====================================================
For example, if a try to get links of page B (iframe) pufff...
"{"Access Denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))"}"
====================================================
5 - The phrase for the more experienced are:
Nothing is impossible! you know!
How can I then perform this procedure?
Thanks
====================================================
Re: [Help]VB6 + Webbrowser + Iframes + Different Domains]
Just figure out what Point A is sending over to Point B, and try to do the same thing. They probably have cross-domain trust built, so sending from your IP address won't work
Re: [Help]VB6 + Webbrowser + Iframes + Different Domains]
It is not that simple = P
anyone have any information?
Re: [Help]VB6 + Webbrowser + Iframes + Different Domains]
You're right. Probably impossible. ;)

that'd be my last post regarding CROSS-DOMAIN TRUST
This should help with the frame issue to some degree:
Code:
Option Explicit
' Use component M$ HTML Object Library
Private Declare Function URLDownloadToFile Lib "urlmon" Alias _
"URLDownloadToFileA" (ByVal pCaller As Long, ByVal szURL As String, _
ByVal szFileName As String, ByVal dwReserved As Long, ByVal lpfnCB As _
Long) As Long
Dim colDocuments As Collection
Private Function GetFile(URL As String) As String
'Purpose: returns file title of a URL or local path
If Mid$(URL, 2, 2) = ":\" Then
'Local Path
GetFile = Right$(URL, Len(URL) - InStrRev(URL, "\"))
ElseIf InStrRev(URL, "/") > InStrRev(URL, ".") Then
'Complete URL
GetFile = Left$(Replace(URL, "http://", ""), Len(Replace(URL, "http://", "")) - 1)
Else
'File
GetFile = Right$(URL, Len(URL) - InStrRev(URL, "/"))
End If
End Function
Private Sub Form_Load()
Dim objDoc1 As HTMLDocument
Dim objDoc2 As HTMLDocument
Dim i As Integer
Dim t As Integer
Set objDoc1 = New HTMLDocument
'Create document element from url
Set objDoc2 = objDoc1.createDocumentFromUrl("http://www.hamcams.com", vbNullString)
'Wait till document has loaded
Do While objDoc2.readyState <> "interactive"
DoEvents
Loop
GetFrames
'Loop through images
For t = 1 To colDocuments.Count
For i = 0 To objDoc2.images.length - 1
'download images and save them in app.path
URLDownloadToFile 0, objDoc2.images.Item(i).href, App.Path & "\Images\" & GetFile(objDoc2.images.Item(i).href), 0, 0
Next i
Next t
Set objDoc1 = Nothing
Set objDoc2 = Nothing
Beep
End Sub
Private Sub GetFrames()
'Purpose: searches all frames in the document(s) and adds them to colDocuments
On Error Resume Next
Dim i As Integer, j As Integer
j = 1
Set colDocuments = New Collection
colDocuments.Add WebBrowser1.document
Do While j < colDocuments.Count + 1
For i = 0 To colDocuments.Item(j).frames.length - 1
colDocuments.Add colDocuments.Item(j).frames.Item(i).document
Next i
j = j + 1
Loop
End Sub
