C#-Web-IE7.0 Problem with correct coding of text of filename in download file form

2 New Member

There is a possibility to show DownloadFile form in web browser using following peace of code
Expand|Select|Wrap|Line Numbers
  1. HttpContext context = HttpContext.Current;
  2. context.Response.ContentType = "application/octet-stream";
  3. context.Response.AddHeader("Content-Disposition","attachment; filename=\"" + fileName + "\"");
but there is somenthing missing because when I use filename with "#" it's displayed in wrong way as "_" in IE 7.0 (in firefox is OK). You have a choice in this window to save and to open the file. When you want to save -> filename will be wrong, when you choose to open filename in eg. word filename shown at the top of the window of word will be ok.

So I used ascii code of # then it save correct filename but when I choose to open it in word it filename has ascii codes.

I assume that I should give correct coding type somewhere in this peace of code ... but I don't know where. Can you help me ?

Hello, Does anyone know where I can find an ASP server side script written in JavaScript to parse text fields from a form method='POST' using enctype='multipart/form-data'? I'd also like it to parse the filename. <form name='form1' method='POST' enctype='multipart/form-data' action='sub.asp'> <input type='text' name='title1' value='value1'> <input type='file' name='file1'>

The "Download file" dialogue prompts the user twice if Open is pressed when using Content-Disposition 'attachment' if, and only if, the script was submitted from a form. If Save As is pressed you don't get the prompt a second gtime btw. If the script is simply executed from a querystring the dialogue appears only once as you would expect. The code I am using to throw content to the browser as an attachment is:

If I add the code for user to download the file (e.g. if(File.Exists(FILE_NAME)){......}), the ASP.NET will give the following timeout error: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. It seems that the download file code is executing before letting the previous code to finish. Even the message print code (message.Text="...";) is not executed.

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,...
