Log In....And Download

[stickman373]

Okay i have a program and it uses the inet control and the webbrowser control.

Here is the scenario:

I use web1 to naviaget to a login page, It enters info and submits, I have web1 navigate to a certain page with a file link on it.

When i get there i download the html source code and find the url for the file.

Then i use inet to download this link.

Now next time i login to a different account right after i'm done with the first account, it logs in but won't download the file?

Why would this happen?

(hope this partially makes sense)

[stickman373]

what i'm basically trying to do is login to an account, but then download a file there with Inet control....

any help?

You should use the DOWNLOAD api to dowload stuff of the net

[stickman373]

i have better inet code so i can get kb/s and bytes transferred.

but it doesn't seem to download from second account.

[Bloodeye]

Hmmmm...difficult to say without seeing everything involved. One thing you don't have to do is download the HTML source code because if you have Navigated to it with the WebBrowser Control, then you can just retrieve the HTML source code by using "outerhtml".....something like this.

Dim sHtmlSource as String
sHtmlSource = WebBrowser1.Document.documentElement.outerHtml

If you want I can take a look at it for you....

[stickman373]

so i want outerhtml not inner?

[stickman373]

btw, when i use inner or outer i get this stupid thing in the url i am extracting:

amp;

what is that?


Should look like this:

%AB%A2%A3%A2%AB%AA%A3%A9&MessageID=13&AttachmentID=2

but i get

%AB%A2%A3%A2%AB%AA%A3%A9& and then i get amp; between then MessageID=13& and then amp; then AttachmentID=2

why?

[stickman373]

well i just used the replace function to get rid of it.

Here is a little bit of what i am doing:

web1.Navigate ("http://" & txttype.Text & ".zzn.com")
 
Do Until web1.ReadyState = READYSTATE_COMPLETE
DoEvents
Loop
 
 
    
With web1.Document
                .All("loginname").Value = lstDwnUsers.Text
                .All("loginpassword").Value = lstDwnPass.Text
                .Forms(1).submit
            End With
 
 
 
    Do Until web1.ReadyState = READYSTATE_COMPLETE
    DoEvents
    Loop
 
 
    web1.Navigate ("http://" & txttype.Text & ".zzn.com/email/english/noframes/mailer/t_baseform.asp?whattodo=showfolder&toolbar=y&FolderID=Inbox")
   
    
    Do Until web1.ReadyState = READYSTATE_COMPLETE
    DoEvents
    Loop
 
    txtHTML.Text = web1.Document.documentelement.outerHTML
 
    sSrchLeft = "totalretard"
    sSrchRight = lstDwnemail.Text
 
    iPos1 = InStr(1, txtHTML.Text, sSrchLeft)
    iPos2 = InStr(iPos1, txtHTML.Text, sSrchRight)
 
    txtHTML.Text = Mid(txtHTML.Text, iPos1 + Len(sSrchLeft), iPos2 - (iPos1 + Len(sSrchLeft)))
    
    txtHTML.Text = Right$(txtHTML.Text, 170)
 
    sSrchLeft = "MessageID"
    sSrchRight = "CurrentChunk"
    
    iPos1 = InStr(1, txtHTML.Text, sSrchLeft)
    iPos2 = InStr(iPos1, txtHTML.Text, sSrchRight)
    
    txtHTML.Text = Mid(txtHTML.Text, iPos1 + Len(sSrchLeft), iPos2 - (iPos1 + Len(sSrchLeft)))
 
    
    
    web1.Navigate ("http://" & txttype.Text & ".zzn.com/email/english/noframes/view/t_view.asp?MessageID" & txtHTML.Text & "CurrentChunk=1"), "C:\temp.html"
   
 
    Do Until web1.ReadyState = READYSTATE_COMPLETE
    DoEvents
    Loop
 
    txtHTML.Text = web1.Document.documentelement.outerHTML
    
    
 
    sSrchLeft = "p_download"
    sSrchRight = lstDownload.Text
    
    iPos1 = InStr(1, txtHTML.Text, sSrchLeft)
    iPos2 = InStr(iPos1, txtHTML.Text, sSrchRight)
    
    txtHTML.Text = Mid(txtHTML.Text, iPos1 + Len(sSrchLeft), iPos2 - (iPos1 + Len(sSrchLeft)))
    
    txtHTML.Text = Replace(txtHTML.Text, "amp;", "")
    
    Inet1.URL = ("http://" & txttype.Text & ".zzn.com/email/english/noframes/view/p_download" & txtHTML.Text & lstDownload.Text)

[stickman373]

then to download i use:

Inet1.Execute , "get"
 
Private Sub Inet1_StateChanged(ByVal State As Integer)
Dim vtData As Variant
Dim strFileName As String
Dim lngLength As Long
 
Select Case State
Case icResponseCompleted
Dim bDone As Boolean: bDone = False
Dim tempArray() As Byte
 
strFileName = txtSavePath.Text & lstDownload.Text
Open strFileName For Binary Access Write As #1
vtData = Inet1.GetChunk(1024, icByteArray)
DoEvents
If Len(vtData) = 0 Then
bDone = True
End If
 
Do While Not bDone
Timer1.Enabled = True
tempArray = vtData
Put #1, , tempArray
 
vtData = Inet1.GetChunk(1024, icByteArray)
DoEvents
ProgressBar1.Value = lngLength
lngLength = lngLength + 1024 \ 1024
On Error Resume Next
ProgressBar1.Value = lngLength
lblBytes.Caption = lngLength & "kb" & " of " & lstSizeDwn.Text & "kb"
If S = 0 Then
Else
lblKB.Caption = lngLength \ S & "kb/s"
End If
If Len(vtData) = 0 Then
bDone = True
End If
Loop
 
Close #1
End Select

I would appreciate it if you could help Bloodeye

[Bloodeye]

The site looks to be some kinds of Email Service.

I see you do a search through the HTML source code. What is it that your downloading. It looks like you are navigating to URL's based upon your search through the HTML source. Aren't there just links that you could programatically click instead of doing it this way?

I'm not sure this is the problem.....just trying to figure out what it is that your doing.

[stickman373]

I am downloading attachments from certain emails in the inbox.

How do i progrmatically click a link?

[Bloodeye]

Something like:
web1.Document.links(7).Click
7 would be the seventh link on that page.

OR
Here's some code for a Sub....you may have to clean it up a bit for what you need.

Dim ImgElem As HTMLImg
Dim AnchorElem As HTMLAnchorElement
 
Public Sub Click_Object(objType As String, strCompare As String) 
 
Select Case objType
     
    Case "image"
         For Each ImgElem In WebBrowser1.Document.images
         If ImgElem.alt = strCompare Then
             ImgElem.Click
             Exit For
         End If
         Next
    Case "anchor"
         For Each AnchorElem In WebBrowser1.Document.links
         'Debug.print AnchorElem.innerText
         'Debug.print AnchorElem.outerText 
         If AnchorElem.innerText = strCompare Then
         'If AnchorElem.outerText = strCompare Then
             AnchorElem.Click
             Exit For
         End If
         Next
    Case "other"
 
End Select
 
End Sub

Usage:

Call Click_Object("image", "My Image")
Call Click_Object("anchor", "My link")

[Bloodeye]

Here's another method to click links

Dim linkToclick As String 
Dim rightlink As String 
Dim i As Integer
 
linkToclick = "http://whatever.the.link.is.com" 
 
For i = 0 To WebBrowser1.Document.links.length - 1 
    rightlink = WebBrowser1.Document.links(i).href 
    If rightlink = linkToclick Then 
        WebBrowser1.Document.links(i).click 
        Exit For
    End If 
Next

[stickman373]

the link changes a lot so it would be hard to do that

but i still don't know why it doesn't download from a second account after i download from the first one.

is there some way to clear inet and webbrowser?

[Bloodeye]

The only thing that enters my mind is that maybe when it goes to navigate to a particular link it get's everything from the cache, because that page is already in the cache.

Try this: Have it go to the First Account, and do it's thing. Then clean out the cache, and see if it works on the Second Account.

BTW: When you save a file, are you saving the files with different names?

[stickman373]

yes i am giving each one a different file name when i save

Also i was thinking if i made it navigate Not reading from cache like this

Call web1.Navigate("http://" & txttype.Text & ".zzn.com", 4)

that us suppose to make it not read from the cache accroding to the link you gave in that other post, i dunno if it will work.

See the funny thing is it works okay on my computer but not on my friends

I dunno what the problem could be

[Bloodeye]

If I remember right, having it not read from the cache doesn't work.
If I were you I would put in a bunch of Message Boxes after every procedure, and then have your friend try it out.Then when
the program cuts out on your friend, you will know where in the
code that it is breaking down at. You could also create a log file
based on this, so you would know where the program wasn't
working.

[stickman373]

okay, i will get back to u after he uses it with message boxes everywhere

Thanks so far!
