Okay. You've probably read my other posts up to now. This is a followup.
The following code is what I've ultimately come up with. it will allow you to download a file from the internet to your computer:

'GetRemoteBinaryFile.vbs
ImageFile = "back.gif"
DestFolder = "C:\"
URL = "http://www.paulsadowski.com/images/back.gif"

Set xml = CreateObject("Microsoft.XMLHTTP")
xml.Open "GET", URL, False
xml.Send

set oStream = createobject("Adodb.Stream")
Const adTypeBinary = 1
Const adSaveCreateOverWrite = 2
Const adSaveCreateNotExist = 1

oStream.type = adTypeBinary
oStream.open
oStream.write xml.responseBody

' Do not overwrite an existing file
oStream.savetofile DestFolder & ImageFile, adSaveCreateNotExist

' Use this form to overwrite a file if it already exists
' oStream.savetofile DestFolder & ImageFile, adSaveCreateOverWrite

oStream.close

set oStream = nothing
Set xml = Nothing

I am still unsure of how to download a file from an https:// website. Any input you can ive would be appreciated.

The code is not working because there's a 404 error every time I try to access the page/file.

ummm....what?

First off, this code won't prompt the user.
Second, the reason its not working is because you gave a bum link.

I also have no idea if .htaccess rules will interfere or not.

So you want an html page to auto download a picture to your computer? Why? your computer usually does this anyway. Take a look in your Temporary Internet folder.

C:\Documents and Settings\USERNAME\Local Settings\Temporary Internet Files\

I have a problem with it,too.
Because .. i want it to get some files to check, whether my script has to download an update.

I want to use it in this way

quote:
Set FSO = WScript.CreateObject("Scripting.FileSystemObject")
Set Folder = FSO.GetFolder(".")

Function getremfile(ImageFile,DestFolder,URL)
Set xml = CreateObject("Microsoft.XMLHTTP")
xml.Open "GET", URL, False
xml.Send
set oStream = createobject("Adodb.Stream")
Const adTypeBinary = 1
Const adSaveCreateOverWrite = 2
Const adSaveCreateNotExist = 1
oStream.type = adTypeBinary
oStream.open
oStream.write xml.responseBody
oStream.savetofile DestFolder & ImageFile, adSaveCreateNotExist
oStream.close
set oStream = nothing
Set xml = Nothing
End Function

getremfile "loginupdate.ini",Folder&"\","~~[...]~~/loginupdate.ini"
getremfile "loginupdate.vbs",Folder&"\","~~[...]~~/loginupdate.vbs"

It works fine, but the ini file looks like this:

quote:
[Updater]#ver=18#size=0#[Files]#File0[...]

"#" is this stupid little box which should be "\n"
In this way my script can't read the ini file.

The file have to look like this:

quote:
[Updater]
ver=18
size=0
[Files]
File0 [...]

Is there any way to fix this ?
I dont know much about working with strings in VBS.

I just know about the PHP command
$stringname = str_replace("#","\n",$stringname);

For atu:

Check this site for some helpful info:
http://www.ericphelps.com/scripting/samples/BinaryDownload/

For Nembo:

you have this:
[Updater]#ver=18#size=0#[Files]#File0[...]

and you want this?:
[Updater]
ver=18
size=0
[Files]
File0 [...]

Use the Split() and Join() functions to do this
Split by #
Join by vbnewline

Yo, TNO, did the code from EricPhelps.com help? 'cause some sites (like i.e. GeoCities) have it blocked that may be downloaded by i.e. Forums and other other downloaders...that may thru their .htaccess.....so i won't work with all URLz

I don't remember where it came from, I was searching alot of places.
I thought that htaccess rules might have limited the script same with <META> tags. Its probably easier to create an instance of IE and browse to the site and download with SendKey.

"downloading a file from internet without prompting a user"

The code I've given so far should be sufficient. If you are trying to silently download some questionable type of file I won't give you any help. The only thing I'll tell you is to convince your "clients" to lower their browser security settings for a perfect stranger (you). I might also give you some help if you can convince me that:
#1) its for a legitimate reason. and
#2) you put some effort into it and show me what you've come up with.

(This is the 2nd post I've seen like this in 20 minutes.......)[V]

I haven't tested this but I believe that this would work on any file copied into the temporary folder.
