Question

Web Browser Question on saving this ones tough.

Asked by: flfmmqp

I am using VB 6.0, IE 5.0, inet and the webbrowser control.  I am going to a website and trying to save the page.  I am saving it into a richtextbox and it saves it but not all of the information.  I am missing all of the pictures and gifs on the page.  I would like all of the information.  Below is some of the code I am using.

   

id_file_save = "c:\RVSPAM\" & Div & mydate & "\" & tracking_number & ".html"

RichTextBox1.Text = Inet1.OpenURL(brwWebBrowser.LocationURL)

RichTextBox1.SaveFile id_file_save, rtftext

More info in case you want it.

In particular I am going to the UPS website, automatically putting in a tracking number and then want to automatically save the page to a file on the hard drive for the future.

An example page would be:

http://wwwapps.ups.com/etracking/tracking.cgi?tracknums_displayed=5&TypeOfInquiryNumber=T&HTMLVersion=4.0&InquiryNumber1=1Z8201EX0341489143&InquiryNumber2=&InquiryNumber3=&InquiryNumber4=&InquiryNumber5=&track.x=31&track.y=8


Thanks for your help,

Michael

I am not positive on the Inet control, but I think the OpenURL only gathers the file specified in the url parameter. This is usually just the HTML so it would not grab all of the graphics, etc. in that file automagically. For that you would need to parse the HTML and use OpenURL on all of the subsequent <img src= you found in the HTML, and save those to a file as well.

There may be another control that can do that, but I am not aware of it.

I do believe you would be better off using the Webbrowser Control in place of the richtextbox... The richtextbox doesn't handle pictures all that well (I know, I know, it does sometimes

You can save the page along with all the graphics usign the webbrowser control. Let me demonstrate:

Private Sub Command1_Click()

WebBrowser1.ExecWB OLECMDID_SAVEAS, OLECMDEXECOPT_PROMPTUSER

End Sub

Private Sub Form_Load()

WebBrowser1.Navigate "http://wwwapps.ups.com/etracking/tracking.cgi?tracknums_displayed=5&TypeOfInquiryNumber=T&HTMLVersion=4.0&InquiryNumber1=1Z8201EX0341489143&InquiryNumber2=&InquiryNumber3=&InquiryNumber4=&InquiryNumber5=&track.x=31&track.y=8"

End Sub

if you want to automate it (i.e., dont prompt user to save to a particular location) then you need to do as mbeers said.

i've always told myself i would try writing this code one day...your question reminded me of it.  its not 100% accurate just yet (still has a bug or two) but heres how it works.  create a folder on your desktop called UPS and paste and run this code.  the images and htm file will all be saved to that folder:


Dim filePath As String
Dim imgCount As Long
Dim imgArr() As String


Public Sub GetPage(strUrl As String, fileName As String)
    Dim b() As Byte
    Inet1.Cancel
    Inet1.Protocol = icHTTP
    Inet1.URL = strUrl
    b() = Inet1.OpenURL(, icByteArray)

    Open fileName For Binary Access Write As #1
    Put #1, , b()
    Close #1
End Sub


Private Sub Command1_Click()
    Dim i, pos As Long
    Dim j As Integer
    Dim fileName As String
    ReDim imgArr(1 To 1) As String
    For i = 0 To WebBrowser1.Document.All.length - 1
        If WebBrowser1.Document.All(i).tagname = "IMG" Then
            pos = InStrRev(WebBrowser1.Document.All(i).src, "/")
            fileName = Right$(WebBrowser1.Document.All(i).src, Len(WebBrowser1.Document.All(i).src) - pos)
            For j = 1 To UBound(imgArr)
                If fileName = imgArr(j) Then
                    GoTo SkipDownload
                End If
            Next
            imgCount = imgCount + 1
            ReDim Preserve imgArr(1 To imgCount)
            imgArr(imgCount) = fileName
            Call GetPage(WebBrowser1.Document.All(i).src, filePath & fileName)
            DoEvents
SkipDownload:
            WebBrowser1.Document.All(i).src = filePath & fileName
        End If
    Next
    Open filePath & "UPS.htm" For Output As #1
    Print #1, WebBrowser1.Document.body.innerhtml
    Close #1
    MsgBox "Webpage downloaded"
End Sub

Private Sub Form_Load()
    filePath = "C:\Windows\Desktop\UPS\"
    WebBrowser1.Navigate "http://wwwapps.ups.com/etracking/tracking.cgi?tracknums_displayed=5&TypeOfInquiryNumber=T&HTMLVersion=4.0&InquiryNumber1=1Z8201EX0341489143&InquiryNumber2=&InquiryNumber3=&InquiryNumber4=&InquiryNumber5=&track.x=31&track.y=8"
End Sub

ok this should be fully functional.  remember though, using this code requires that the document be completely downloaded since we must alter it.  you can put this code in the webbrowser's documentcomplete event to automate saving pages once they are navigate to automatically:

Dim filePath As String
Dim imgCount As Long
Dim imgArr() As String


Public Sub GetPage(strUrl As String, fileName As String)
    Dim b() As Byte
    Inet1.Cancel
    Inet1.Protocol = icHTTP
    Inet1.URL = strUrl
    b() = Inet1.OpenURL(, icByteArray)

    Open fileName For Binary Access Write As #1
    Put #1, , b()
    Close #1
End Sub


Private Sub Command1_Click()
    Dim i, pos As Long
    Dim j As Integer
    Dim fileName, tag As String
    ReDim imgArr(1 To 1) As String
    For i = 0 To WebBrowser1.Document.All.length - 1
        tag = WebBrowser1.Document.All(i).tagname
        Select Case tag
            Case "IMG", "INPUT"
                If tag = "INPUT" Then
                    If WebBrowser1.Document.All(i).Type <> "image" Then GoTo SkipAll
                End If
                pos = InStrRev(WebBrowser1.Document.All(i).src, "/")
                fileName = Right$(WebBrowser1.Document.All(i).src, Len(WebBrowser1.Document.All(i).src) - pos)
                For j = 1 To UBound(imgArr)
                    If fileName = imgArr(j) Then
                        GoTo SkipDownload
                    End If
                Next
                imgCount = imgCount + 1
                ReDim Preserve imgArr(1 To imgCount)
                imgArr(imgCount) = fileName
                Call GetPage(WebBrowser1.Document.All(i).src, filePath & fileName)
                DoEvents
SkipDownload:
                WebBrowser1.Document.All(i).src = filePath & fileName
SkipAll:
        End Select
    Next
    Open filePath & "UPS.htm" For Output As #1
    Print #1, WebBrowser1.Document.documentElement.innerhtml
    Close #1
    MsgBox "Webpage downloaded"
End Sub

Private Sub Form_Load()
    filePath = "C:\Windows\Desktop\UPS\"
    WebBrowser1.Navigate "http://wwwapps.ups.com/etracking/tracking.cgi?tracknums_displayed=5&TypeOfInquiryNumber=T&HTMLVersion=4.0&InquiryNumber1=1Z8201EX0341489143&InquiryNumber2=&InquiryNumber3=&InquiryNumber4=&InquiryNumber5=&track.x=31&track.y=8"

Sorry I was trying to increase the points by the whopping five more I have.  Sorry for the low point total.  I am new to the board but you can bet I am going to become a regular.

AzraSound your answer was great and did exactly what I wanted it to do.  Thanks a million.

I would also like to thank Orbitaltech and mbeers for trying to help.  I am sure you guys were trying to send me on the right path but AzraSound gave me everything I needed.  I have a feeling He/She is addicted to this board.

How do I give you these points.

Michael
