.Net attach file to email.

http://www.asp.net/learn/videos/video-439.aspx

right, but how do i get the returned pdf file?  if you run the same on the page i attached, it just renders and opens up asking if you want to save or open.  i would like to save it automatically, then attach it to the email.  is this possible?

Attaching files to email messages is a strait forward practice in .Net.
Please check the code sample below

Dim message As MailMessage = New System.Net.Mail.MailMessage("Fromaddress@YourCompnay.com", "ToAddress@domain.com")
Dim MyAtatchment As System.Net.Mail.Attachment
MyAtatchment = New Net.Mail.Attachment("c:\folder\File1.pdf")
message.Attachments.Add(MyAtatchment)
Dim client As System.Net.Mail.SmtpClient = New System.Net.Mail.SmtpClient(SMTPServer, SMTPServerPort)
 client.Credentials = New System.Net.NetworkCredential(SMTPUserName, SMTPUserPassword, SMTPDomain)
client.Send(message)

no my issue is not with attaching the file, my issue is with saving the pdf file to access it.

please check out the link i posted.  

it creates a pdf file on the fly for a reporting services page.  problem is it comes up to the user save/open.

I don't want that to come up.  I want to save the pdf file automatically so i can access it using similar code to what you just posted.

Ok

You need to remove all the code starting from the link contains rsExec.Render(format, deviceInfo, out extension, out encoding, out mimeType, out warnings, out streamIDs);
and replace it with the attached code to save the fiile to local disk. once you save it to the disk, then you can attached it to your email.

byte[] File = rsExec.Render(format, deviceInfo, out extension, out encoding, out mimeType, out warnings, out streamIDs);
System.IO.StreamWriter sw =new System.IO.StreamWriter("c:\Test.pdf");
sw.Write(File);
sw.Close();

Please check the updated code if you had any issues.

byte[] File = rsExec.Render(format, deviceInfo, out extension, out encoding, out mimeType, out warnings, out streamIDs);
System.IO.StreamWriter sw =new System.IO.StreamWriter("c:\\Test.pdf");
string FileString = System.Text.Encoding.ASCII.GetString(File);
sw.Write(FileString);
sw.Close();

no errors, but it still comes up to save it.  it created the file, but there is nothing in it??

You need to remove the following lines from the page code:
  Response.AddHeader("content-disposition", "attachment; filename=pdf01.pdf");
        Response.OutputStream.Write(results, 0, results.Length);
        Response.End();

ok this is what i have now.  i commented out a bunch of stuff.

now it doesn't prompted me to do the save, and i see a file craeted at my root of c, but there is no data in it.

//results = rsExec.Render(format, deviceInfo, out extension, out encoding, out mimeType, out warnings, out streamIDs);
 
        byte[] File = rsExec.Render(format, deviceInfo, out extension, out encoding, out mimeType, out warnings, out streamIDs);
        System.IO.StreamWriter sw = new System.IO.StreamWriter("c:\\pdf01.pdf");
        string FileString = System.Text.Encoding.ASCII.GetString(File);
        sw.Write(FileString);
        sw.Close(); 
 
 
 
        //Response.AddHeader("content-disposition", "attachment; filename=pdf01.pdf");
        //Response.OutputStream.Write(results, 0, results.Length);
 
        //This is very important if you want to directly download from stream instead of file
        //Response.End();

LOL yea i commented those out.  so i get a file created but nothing there.

Your code seems to be fine now,
Now, you need to make sure that your report has some data in the first palce.
Then try to check the length of FileString and File vairables to track where the data get lost..
Please try this and post your findings here

i get these errors.  how do i check the length of these variables?

yes the report has some data.  when i do it the orignal way it works fine.

Error      1      'string' does not contain a definition for 'length'      C:\Data\Development\RsPdf\RsPdf.aspx.cs      91      35      C:\...\RsPdf\
Error      2      'System.Array' does not contain a definition for 'length'      C:\Data\Development\RsPdf\RsPdf.aspx.cs      92      29      C:\...\RsPdf\

OK i stepped threw when it was executing and held cursor over each var and both has data.

Good news.
Did you check the size of the created file?

?? what do you mean?  can you post a code sample for that.

We need to check the prosperities of the created file c:\pdf01.pdf and see its size.

following code prints out 7345


FileInfo fi = new FileInfo("c:\\BIGTEST.pdf");
        long len = fi.Length;

        Response.Write(len);

Ok. great..
The problem seems to be related to file encoding..
Please replace System.IO.StreamWriter sw = new System.IO.StreamWriter("c:\\pdf01.pdf");
 with the code below and let me know.

 System.IO.StreamWriter sw = new System.IO.StreamWriter("c:\\pdf01.pdf", false, System.Text.Encoding.UTF8);
