Copy a file from the internet as a source.

How would I go about copying a file using the internet as a souce location?

I want to be able to provide my users a way of updating tables and programs from a location stored in a folder of my web page. On clicking a pushbutton in the program, files would be downloaded from across the internet to their local drive.

Thanks

Here is a code snippet that may be useful if your app needs to download a
file from a web site:

extern culong URLDownloadToFile( cptr, cstring, cstring, culong, culong) URLMON.DLL from "URLDownloadToFileA"

URL = "http://www.vicmcclung.com/prev32.zip"
File = "prev32.zip"

URLDownloadToFile( null, URL, File, null, null)

The above code will download the printer/preview class zip file from my web
site to your current directory.

NOTE:
urlmon.dll may be missing on some older versions of Win95. Install IE 4.0
or later to be sure it is included.

That seems to work great. Thanks.

I'm using the URLDownloadToFile function of Internet Explorer to provide a program update service for my application to my customers. I want to display a download status of a text message of the percent completed. There is a supporting method, IBindStat
usCallback::OnProgre
ss, that performs this function, but I am not sure how to use it. Could someone please provide me with a brief snippet on the use of the OnProgress method.

As an alternative, try this solution by Marc VdB:

Roland,

Thanks for the quick reply (4 minutes). That looks like just what I was looking for. No sense reinventing the wheel. Very much appreciated.

David.
