I'm needing to send around 500-2500 emails out at a time to internal email accounts. I'm wondering which was would be faster both for the mail server and for my client app. Should I send multiple emails with just different TO addresses, or just one with multiple BCC addresses? I tried testing this by sending a bunch to my own email and the multiple emails method work, but with the BCC and a single message I only get that single message in my inbox. Shouldn't I be getting as many copies as the number of times I put my address in the BCC line?
My site sends confirmation emails from a purchase. 95% of the time, it works. The other 5% after clicking the 'Confirm' button that runs the payment and should send the email, i get the following exception:
Details: Exception: Failure sending mail.
Inner Exception: Unable to connect to the remote server
Inner Exception(2): A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 72.167.234.197:25
The code to send the email is this:
Dim smtpClientPayPalSuccess As System.Net.Mail.SmtpClient = New System.Net.Mail.SmtpClient() smtpClientPayPalSuccess.Host = "relay-hosting.secureserver.net" smtpClientPayPalSuccess.Send(mailMessagePayPalSuccess)
FYI: I have confirmed with the hosting that I don't need any credentials, or a different port number than 25. This is also running over https. why this would be happening only a small percentage of the time?
is there a way to increase the maximum 10 GB size limit of SQL Express? http://www.microsoft.com/express/Database/http://www.microsoft.com/sqlserver/2008/en/us/editions-compare.aspx
In my asp .net project, my main page receives URL as a parameter I need to download internally and then process it. I know that I can use WebClient's DownloadFile method however I want to avoid malicious user from giving a url to a huge file, which will unnecessary traffic from my server. In order to avoid this, I'm looking for a solution to set maximum file size that DownloadFile will download.
Then I found this solution online to handle the error if someone tries to upload file bigger than 10 MB
[Code]....
This works great on my local machine but when I try to run it from Production server , It still shows me the "Internet Expolrer cannot display webpage". I just want to display a nice message to user when He tries to upload file larger than 10 MB.
I have developed an application using Winforms that connects to the Database using WCF services. All the services are working fine except those that return huge amount of data from the database. I did increase the size of the maxReceivedMessageSize and maxBufferPoolSize to 9223372036854775807 in the Config file of the client which I believe is the largest but I still get the error message "The maximum message size quota for incoming messages (65536) has been exceeded". I am using visual studio 2010 with VB.Net programming language on the client side and C sharp on the server.
I also goggled but the nearest solution I got was to increase the maxReceivedMessageSize which I did but in vain. Below is the detail of the error: "The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.

Im generating a PDF file. Normally I send this to the user using a .ashx file, where the user can directly download it from his browser (see that code below).
Protected Function getfile() As MemoryStream Dim stream As MemoryStream = New MemoryStream If document.PageCount > 0 Then document.Save(stream, False) 'Context.Response.Clear() 'Context.Response.ContentType = "application/pdf" 'Context.Response.AddHeader("Content-disposition", "attachment;filename=TicketEZ_tickets_" + eventname + ".pdf") 'Context.Response.AddHeader("content-length", stream.Length.ToString) 'Context.Response.BinaryWrite(stream.ToArray) 'Context.Response.Flush() Return stream stream.Close() 'Context.Response.End() End If
But now I want to send this file as an email attachment...how can I do that? I tried this, but that doesnt work...(Value of type 'System.IO.MemoryStream' cannot be converted to 'String')
Dim att As New System.Net.Mail.Attachment(getfile) Msg.Attachments.Add(att)
I have a strange problem with sending email via asp.net.
I adding to my email an attachment with long name ("Xxxxxxxx ąę łóxxxx yyyyyyyyyńęąąyy bbbbbbbbbb b wwwwwwwww wwwwwww ooooooooo" - polish chars included). Next I receiving that email with that file but I can't read the file. There is like damaged, with different name - ""=_utf-8_B_WHh4eHh4eHggxIXEmSDFgsOzeHh4eCB5" and the file size is a little bigger.
I know how to send an email. But now I want to send an email with an attachment. I also want to allow the user to browse for and then select the attachment. I cannot seem to find any info on this. All the articles I find show how to attach a file where you know the path and file name. I want the user to browse their drive, select a file, and then send an email with this attachment.
Is there a way to send the same email to multiple recipients but also send with an attachment to only 1 of them?eg. I have a form that gets filled out, the user gets a copy of the form with an attachment (file sits on server). The site owner also wants the email (through bcc) but without the attachment.
I have completed sending attachment/pdf with email.
I have to send password protected attachment/pdf while sending email so that reciepeint should be asked to enter password while opening attachment/pdf and he will open attachment/pdf only after entering password.
Protected Sub btnExport_Click(sender As Object, e As EventArgs) Response.ContentType = "application/pdf" Response.AddHeader("content-disposition", "attachment;filename=TestPage.pdf")
[Code].....
But i want the file to save in the particular folder....
