Writing a batch file to download many .pdf files...

[John Connor]

I am attempting to quickly download nearly 1000 .pdf files from a website. Each .pdf has a unique url, and they run in sequence from 1-1000.

I would like help writing a batch file that I could run once and would (in the background) access the .pdf via its url, save a copy, and then move on to the next one.

Similar to (this is sloppy C++ and English combined, its been a while since i've used the language and I do not know Batch files at all):

int a = 1;
string URL;
for(int i=1; i<1000; i++,a++) {
    URL = "http://www.site.com/file"+a+".pdf"
    open page in background URL;
    save file using existing webpage title name;
}
 

If it is easier, I also have a text file that includes a list of all the URLs in sequence, so if accessing that file to acquire the text of the URL would be easier, please help me with that instead.

Thanks,
John

This is how it's done in VB6.
It's also possible to load the textfile with URL's in a list and run trough the list to load and save them.
This example loads the logo of Bytes, saves it on the C:\ and displays it in a picturebox.

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
 
Private Sub Form_Load()
    ' Download the file.
    URLDownloadToFile 0, _
        "http://bytes.com/images/logo4.gif", _
        "C:\logo4.gif", 0, 0
 
    ' Display the image.
    picBanner.Picture = _
        LoadPicture("C:\logo4.gif")
 
    ' Size to fit.
    Me.Width = picBanner.Width + 2 * picBanner.Left + _
        (Me.Width - Me.ScaleWidth)
    Me.Height = picBanner.Height + 2 * picBanner.Left + _
        (Me.Height - Me.ScaleHeight)
End Sub
