Download file from dynamic link using VBScript or Powershell

I'm trying to create a VBScript or Powershell script to get the file from dynamic link (e.g. http://www.pepperresources.org/LinkClick.aspx?fileticket=B1doLYYSaeY%3d&tabid=61 )

I should get any file that will be downloaded from that kind of link (whether it will be PDF or CSV or Excel) to the specified folder. Any idea if I can do this using VBScript or Powershell Script?

Have been tried to searched the solution for this but no luck.

Thanks before for any helps.

The URL has to be 100% correct. Unlike a browser there is no code to fix urls.

The purpose of my program is to get error details.

How I get a correct URL is to type my url in a browser, navigate, and the correct URL is often in the address bar. The other way is to use Properties of a link etc to get the URL.

Also Microsoft.XMLHTTP maps to Microsoft.XMLHTTP.1.0. HKEY_CLASSES_ROOT\Msxml2.XMLHTTP maps to Msxml2.XMLHTTP.3.0. Try a later one

Try this way using xmlhttp. Edit the url's etc. If it seems to work comment out the if / end if to dump info even if seeming to work. It's vbscript but vbscript works in vb6. 

 On Error Resume Next
 Set File = WScript.CreateObject("Microsoft.XMLHTTP")
 File.Open "GET", "http://www.microsoft.com/en-au/default.aspx", False
 'This is IE 8 headers
 File.setRequestHeader "User-Agent", "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0; Trident/4.0; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 1.1.4322; .NET CLR 3.5.30729; .NET CLR 3.0.30618; .NET4.0C; .NET4.0E; BCD2000; BCD2000)"
 File.Send
 If err.number <> 0 then 
    line =""
    Line  = Line &  vbcrlf & "" 
    Line  = Line &  vbcrlf & "Error getting file" 
    Line  = Line &  vbcrlf & "==================" 
    Line  = Line &  vbcrlf & "" 
    Line  = Line &  vbcrlf & "Error " & err.number & "(0x" & hex(err.number) & ") " & err.description 
    Line  = Line &  vbcrlf & "Source " & err.source 
    Line  = Line &  vbcrlf & "" 
    Line  = Line &  vbcrlf & "HTTP Error " & File.Status & " " & File.StatusText
    Line  = Line &  vbcrlf &  File.getAllResponseHeaders
    wscript.echo Line
    Err.clear
    wscript.quit
 End If

On Error Goto 0

 Set BS = CreateObject("ADODB.Stream")
 BS.type = 1
 BS.open
 BS.Write File.ResponseBody
 BS.SaveToFile "c:\users\test.txt", 2

Also see if these other objects work.

C:\Users>reg query hkcr /f xmlhttp

HKEY_CLASSES_ROOT\Microsoft.XMLHTTP
HKEY_CLASSES_ROOT\Microsoft.XMLHTTP.1.0
HKEY_CLASSES_ROOT\Msxml2.ServerXMLHTTP
HKEY_CLASSES_ROOT\Msxml2.ServerXMLHTTP.3.0
HKEY_CLASSES_ROOT\Msxml2.ServerXMLHTTP.4.0
HKEY_CLASSES_ROOT\Msxml2.ServerXMLHTTP.5.0
HKEY_CLASSES_ROOT\Msxml2.ServerXMLHTTP.6.0
HKEY_CLASSES_ROOT\Msxml2.XMLHTTP
HKEY_CLASSES_ROOT\Msxml2.XMLHTTP.3.0
HKEY_CLASSES_ROOT\Msxml2.XMLHTTP.4.0
HKEY_CLASSES_ROOT\Msxml2.XMLHTTP.5.0
HKEY_CLASSES_ROOT\Msxml2.XMLHTTP.6.0
End of search: 12 match(es) found.

Also be aware there is a limit on how many times you can call any particular XMLHTTP object before a lockout occurs. If that happens, and it does when debugging code, just change to a different xmlhttp object
