I have an Excel VBA that opens a webpage and clicks a link. The link runs a JavaScript that generates a PDF page in a new IE window. So far all is fine, but I have not found out how to save (download) the PDF. Below is my VBA, test it and you can see what I mean:

Rich (BB code): 
Sub GeneratedPDF()    Dim IExplorer As InternetExplorer
    Dim TheURL As String
    Dim HTMLdoc As HTMLDocument
    Dim TheLink As HTMLLinkElement
 
    TheURL = "core.purus.se/PurusWeb/Navigate/Document.aspx?DBDocId=13284"
    Set IExplorer = New InternetExplorer
    With IExplorer
        .navigate TheURL
        .Visible = True
        While .Busy Or .readyState <> READYSTATE_COMPLETE: DoEvents: Wend
        Set HTMLdoc = .Document
        Set links = HTMLdoc.getElementsByTagName("a")
        i = 0
        Set TheLink = Nothing
        'And HTMLdoc.links(i).className = "ddmenu"
        Do While i < HTMLdoc.links.Length
            If HTMLdoc.links(i).className = "PDFLink" Then
                Set TheLink = HTMLdoc.links(i)
                Debug.Print TheLink
                Exit Do
            End If
            i = i + 1
        Loop
    End With
    TheLink.Focus
    TheLink.Click
    IExplorer.Quit
End Sub

This isn't a full solution but perhaps it will help.

I was able to download the PDF with this code.
Code: 
Option Explicit

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

Sub DownloadFilesFromWeb()
Dim strURL As String
Dim strFileName As String
Dim strSavePath As String
Dim returnValue As Long



    strURL = "http://core.purus.se/PurusWeb/Navigate/PdfQueue.aspx?&FORCE=9720&Add=Product&Catalog=Product&DocId=1&Style=SimplePdf&Hires=&Level=&Language="

    strFileName = "MiniBrage50.pdf"

    strSavePath = "C:\test\" & strFileName

    returnValue = URLDownloadToFile(0, strURL, strSavePath, 0, 0)

    If returnValue = 0 Then
        Debug.Print "Success!"
    Else
        Debug.Print "Did not succeed."
    End If


End Sub

I got the address for the file from the source code of the window that pop-ups.

See the src attribute of the frame here:
HTML: 
<head>
		<title>PDF-dokument</title>
	</head>
	<frameset rows="*">
		<frame name="Main" src="PdfQueue.aspx?&FORCE=9720&Add=Product&Catalog=Product&DocId=1&Style=SimplePdf&Hires=&Level=&Language=">
	</frameset>

You should be able to add to your code to retrieve the address and then use the download code to retrieve the document.
