More File download questions

I am trying to implment a file download via a link such that when clicked,
instead of starting the default application for that type of file the user
will be presented with a download dialog window. Well, thanks to Steve Orr,
I have that working. However, I still have a few issues. First, the
download dialog does not have the name of the file being downloaded in the
"File name" field, instead it has the name of the aspx page that have the
code to send the file to the client. Second, also in the download dialog,
the "File type" field has nothing in it. The code from my aspx page that is
doing the download is below. Is there ome other header that I can add that
will cause the download dialog to have the correct file name and file type
in it? Also, I'd liek to refresh the clling page so that the list of items
left to download nolonger includes the item just downloaded. If there
anyway to do that in this aspx page (adding a response.redire ct to the page
that the download link is on doesn't work). I tried adding and event handler
on the download page that refreshed when the link was clicked but it
refreshed before the download started. Thanks for any help you can provide.

Hi all, How does one allow a user to download a file WITH selecting where it should be downloaded to on their machine? Also, when using the WebClient.Download method, will the destination path written in Windows format (backslashes, etc.) translate across client platforms? Is there a better way? WebClient wc = new WebClient(); wc.DownloadFile(Server.MapPath(@"Downloads\MyFile.pdf"), @"C:\Temp\TheirFile.pdf");

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
