Hello, I'm new to ASP.NET, so please be patient.
I need to have a download page that serves a Save As dialog when user clicks the button, but I don't know how to go about modifying the code I found on the internet.
<br />
Response.Clear()<br />
Response.AppendHeader("content-disposition", "attachment; filename=ap_06_fulldress.jpg")<br />
Response.ContentType = "text/plain"<br />
Response.WriteFile(Server.MapPath("/downloads/wallpapers/ap_06_fulldress.jpg"))<br />
Response.Flush()<br />
Response.End()<br />
I would like to pass filenames as variables to reuse the code as much as possible instead of having a function for each download, which would not be very efficient.
Any help appreciated. Thanks.

if you want to pass filename as variable than this would help
first sava your filename in variable like
string filename="/downloads/wallpapers/ap_06_fulldress.jpg";
now pass this variable in place of file like
Response.Clear()
Response.AppendHeader("content-disposition", "attachment; filename=ap_06_fulldress.jpg")
Response.ContentType = "text/plain"
/*** change ***/
Response.WriteFile(Server.MapPath(filename))
/*** ***/
Response.Flush()
Response.End()
In this way you can change the filename as u like just pass the filename in variable and the code will work...

-- submit your master form if any values from server is needed else just do further proceedings

Authentication is an important issue in these cases.
Can you provide a version with authentication.

Hi there!! Thanks for your help. Your code worked with some workaround on dotnet 1.1 but on dot net2.0 I'm using following code.
'create the mail message<br />
Dim mail As New MailMessage()<br />
<br />
Try<br />
<br />
<br />
'set the addresses<br />
'to specify a friendly 'from' name, we use a different ctor<br />
mail.From = New MailAddress(TextBox1.Text)<br />
mail.To.Add(TextBox2.Text)<br />
<br />
'set the content<br />
mail.Subject = "This is an email"<br />
mail.Body = TextBox3.Text<br />
<br />
'send the message<br />
Dim smtp As New SmtpClient("127.0.0.1")<br />
<br />
smtp.Send(mail)<br />
Catch ex As Exception<br />
Label1.Text = ex.ToString<br />
End Try
I'm getting following exception
System.Net.Mail.SmtpException: Failure sending mail. ---> System.IO.IOException: Unable to read data from the transport connection: net_io_connectionclosed.<br />
at System.Net.Mail.SmtpReplyReaderFactory.ProcessRead(Byte[] buffer, Int32 offset, Int32 read, Boolean readLine)<br />

at System.Net.Mail.SmtpClient.Send(MailMessage message)<br />
at Default2.Button1_Click(Object sender, EventArgs e) in c:\inetpub\wwwroot\Try1\Default2.aspx.vb:line 25
Any help would be highly appreciated.

I'm not sure about the framework 2.0

Hi got it to work.I'm just posting the things which should be taken care of so that others could benefit.
IIS -> Default SMTP Virtual Server ->Right Click Properties -> Access Tab ->Connection (Also Relay) Add your server name (For example 127.0.0.1 localhost). It will work.
Thanks

is there a .exe file in asp.net?
|
|
|
|
|
.exe will be generated after you deploy the web application.
Best regards,

The asp.net generated a dll for all ur classes and the webforms in the aspx format, so there are no exe files
