Error BC30456: 'Dispose' Is Not A Member Of 'System.Net.Mail.SmtpClient'
Jun 21, 2012
The exact error I am getting in Visual Studio 2012 is:
error BC30456: 'Dispose' is not a member of 'System.Net.Mail.SmtpClient'.
Dim SmtpServer As New SmtpClient()
Dim mail As New MailMessage()
SmtpServer.Port = 25
[code]....
This should be an obvious error. You would think I was using .net framework 3.5 or lower as Dispose() was only added as a member to SmtpClient in .net 4.0. However, I am using 4.0!In the website property pages it states 4.0. Is there somewhere else that I need to set as 4.0?
Pretty simple question. I'm quite certain I have the Class, method, codebehind, etc linked properly. Lot's of posts online say that this has something to do with compiling and/or dll/bin
I'm having trouble with a more complex program, so I've created a simple program to highlight my issue (see code block below). When I declare a Collection generically (like I have below) and try to call IndexOf, I get the following compiler error:
'IndexOf' is not a member of 'Microsoft.VisualBasic.Collection'. (BC30456)
If I instead declare my Collection as a collection of strings (Public mycollection As New Collection(Of String)), I then have access to the usual methods, but the .Add method then only allows a single string to be passed to it. This means that I can't use a key, which seems to be the point of a collection. Is there any way to have a general, keyed collection that can use IndexOf?

Now when i run the page i get this error " BC30456: 'bindData' is not a member of 'shoppingCart1.ShoppingCart'.
I'm trying to create an application that sends an email to an smtp-server. The server is not set fixed, but will be looked up according to the domainpart of the email-address where the email should be sent to.
[Code]...
It would be quite useful, to know if the message was accepted by the mailserver and the message was successfully sent. What I am able so far is, that I can get the SMTP-Server error code (if there was an error (StatusCode 5xx) by using the System.Net.Mail.SMTPClient Object and its SendAsync Function. There, if there was an error, I get an Exception-Object in the Callback-Event of the SMTPClient
I'm well aware that not every mailserver will tell me if the mailaccount truly exists and then reject my mail with an errorcode but instead just accept the message and then delete it. Therefore I would be grateful for another Method to check if the mail was sent (note: not read, that would be the read confirmation)
The final purpose would be: Try to send an email to a recipient using it's domains mailserver and if it fails, proceed according to the errorcode (user does not exist -> abort / mailserver did not respond -> use another mailserver if available).
I have an issue where emails sent out via the SmtpClient class in .NET go directly into the outlook junk mail folder (Outlook 2003 and 2007). If I send the exact same email (same body, same subject, to and from the same accounts as I use in .NET) from Outlook itself, it will come in fine and not be marked as junk mail. The only difference is the extra headers that Outlook appends to the email when it is sent directly from Outlook.
I am tring to send e-mail used VB 2008. Below is my code. The error message I am getting is "5 Failure sending mail at System.Net.mail.client.send(MailMessage message).I have two questions. 1.) What am I doing wrong? & 2.) Is there a way the get a more description error message.

I posted the following description before and the only suggestion that I received was to switch to System.Net.Mail code. I did switch and I continue to get the same randow and intermittent error.
Problem: Failure of in-house written VBScript that runs from a web page which calls CDO library to send an SMTP message.
Systems: About 100 Windows XP, Professional, Version 2002, SP2 clients using IE6 and IE7. Symantec 10.1.6.6010. All Microsoft patches are regularly installed.
Symptoms: Web application has sent messages for years without error. About December 2007 an intermittent failure began. About 5% of the SMTP messages are not being sent.
Research 1: Added code to trap error and got error number -2147220973 and error description, "The transport failed to connect to the server".
Research 2: Verified that the failed messages were not leaving the client by using a hardware network sniffer.
Research 3: Used SysInternals/ TCPView to monitor while sending messages.It didn't always show when a message was sent.Perhaps it needs to operate at a lower speed than 1 second. When TCPView did show something it was that ccApp.exe,Symantec antivirus,was communicating with the SMTP server.
Research 4: Reviewed all tools available in Sysinternals but didn't find any way to monitor the messages better than TCPView.
Research 5: Placed error checks throughout the code and proved that the error is in the iMsg.Send command.
I haven't had this problem before. For some reason, when I declare a variable,I.E.rand as a new random(), and try to use rand.Next, i get an error saying 'Next' is not a member of system.array. Not sure why this is happening.
I'm having trouble understanding why i'm getting the error 'add is not a member of system.array'I'm using an arraylist and when I hover over my declaration of memberarray As ArrayList() the tooltip states 'Dim memberarray as System.Collections.ArrayList()[code]
Dim elements As System.ServiceModel.Channels.BindingElementCollection = _Client.Endpoint.Binding.CreateBindingElements elements.Find(Of System.ServiceModel.Channels.SecurityBindingElement).EnableUnsecuredResponse = True
This is the error,i am getting in my code.the reason is the code is developed in some other environment.while trying to run in my system it giving error.i gone throug the service model dll,But EnableUnsecuredResponse is not a member in that.And i have tried to install some patches also.But i am not able to resolve the error.this is the patch i have installed ( link ) And EnableUnsecuredResponse is a member in system.servicemodel(framework(4.0)),i am using framework(3.5)

This has worked for over one or two years. Today I realized upon testing I get the following error:The procedure entry point IstrcmpiI could not be located in the dynamic link library MSDART.DLL.Upon some research I found that maybe I needed to install MDAC 2.8, which i downloaded and installed today, however i still get the same error. I have had my communications and network admins check traffic and connectivity to the smtp server and all is working fine. Yet I still get the error.
I've implemented with Visual Basic 10 an application for Net Framework 4 with functionality to send files via e-mail using System.Net.Mail. It works well except when it comes to sending an XML file whose name contains accents. In the latter case the UTF-8 name is not correct, so Widows Mail Life presents him with name consisting of a set of meaningless characters. Furthermore, the content has lost the format of lines and spaces, presented part of MIME type information in the header, so that it is unreadable XML readers. However, with a name without accents is sent successfully.[code]....
