I want to send emails to all the followers of my website as soon as a new article is submitted.
PROBLEM: I want to send the emails asynchronously using threading or a windows service. I am not sure about windows service as I am using a shared hosting. But my real concern is that I want to send out the emails only when traffic is low in my site. How do I go about this? Ho do I check if traffic is low or not?

Fax is not getting visible in fax console's outbox. I saw three files in "C:ProgramDataMicrosoftWindows NTMSFaxQueue" for every sent fax but this is not visible in fax queue. I also observed that, when I am trying to send the fax from windows application then it works but anyhow it is getting failed when I am trying to send that from windows service.
I have following code :
Dim oFaxSvrType As Type = Type.GetTypeFromProgID("FaxcomEx.FaxServer")
Dim oFaxSvr As Object = Activator.CreateInstance(oFaxSvrType)
Dim oFaxDocType As Type = Type.GetTypeFromProgID("FaxcomEx.FaxDocument")

Now there's a user "A" who has 100 followers...now what i want to do is whenever user "A" submits an article in the website all his followers should get an email with the article link...that is okay i can do it.
Problem: Now, there's a submit button on the page which stores the article in the DB and sends email to the followers...as there are many followers it takes a lot of time sending the emails...so the page keeps showing loading msg till all the emails are sent..how can i send all the emails asynchronously ??
i mean after the article has been submitted ...the emails should go automatically to the followers without putting the email sending function in the click event of the button....hope am not confusing you folks.
can i do something like store the article in the DB , redirect to the article page , start sending emails in a batch of 10 per 10 mins automatically...this process should start as soon as an article has been submitted by an user.
What are the different ways to send the emails using vb.net?
View 4 RepliesI have been trying to make my own app for sending emails. But I have been trying to make it where I don't have to sign into my hotmail account, it just does it automatically. Then all I need to do is fill out the recipients, subject, and body for the message and hit send but I am having issues. I can't for the life of me get it to work. After a week of messing around with it and scouring the internet for help, I have gotten to where the only error I get is, failure to send message.

My latest project requires both sending and receiving emails. Now i know how to send emails using a gmail account, but what im having incredible difficulty with, is accepting emails. What i want, is to have a program that both has the ability to send emails, and capture emails being sent to the logged in user, and place them in an inbox list. I was wondering if anyone knew how to receive emails with a program, even temporarily, so that when an email is sent to the user, my program knows about it, and can take the body from the email, and place it in say a textbox.

I am using VB5 on a Windows XP SP3 computer.I have an application that send emails to customers that have birthdays today and that bought a product from me today. If I run the application several times with the same search criteria with the same customers and the same date and time, I "may" or "may not" get the save Emails sent out.I am using a MAPI Signon prior to the birthday select and MAPI Signoff after the birthday select; another MAPI Signon prior to the sales today select and MAPI Signoff after the sales today select.I count the emails that are supposed to be produced in each select above and the counts are correct. It's the emails that may not agree with the counts.What could cause this?

View 5 Repliesi have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.

View 4 RepliesIn the past I had the indexing service installed on a Windows Server 2003 and used it to index files for my website. I did this by executing an OleDbCommand with a query and a connection string.How do I accomplish the same thing with the new "Windows Search Service" (Windows Server 2008) by using VB.NET? Does this work the same way so that I only need to change the Provider name which has been "MSIDXS.1" up to now? Case true, what is the new Provider name?
View 1 RepliesWe are having problems with sending back to back emails on one of our web sites. The site is built with .net framework 2.0.We can send the first email without any problems on every try. But to send a second email you need to wait about 20-30 minutes.the problem.One thing we tried was changing the smtp email server. We tried a third party smtp server but the same problem persisted. So I think the problem is not with the smtp server but with our .net code.

When you create a Windows Service, you create a list of the services you want to start. The default is this:
ServicesToRun = New System.ServiceProcess.ServiceBase() {New Service}
Can you have multiple instances of the same Service class (that bind to different addresses or ports), like this?
ServicesToRun = New System.ServiceProcess.ServiceBase() {New Service("Option1"), New Service("Option2")}
Or will that cause problems? Should we use two different classes instead?

View 4 RepliesI need to pass a block of binary data to a web service. The object I'm passing is part of an API, so the Serialize/Deserialize/Byte functions are built-in to the API class. It is not explicitly XML Serializable as far as I can tell.
Unfortunately, whenever I pass the data to my web service, even as an encoded string, the service returns a "(400) Bad Request" error. If I remove the encoded data and replace the variable with a simple string, an appropriate response is returned, ruling out authentication, service errors, etc.
'Convert the byte array into an encoded string'
Dim unicodeEncoder As New UnicodeEncoding()
Dim serializedData As String = unicodeEncoder.GetString(myObject.Bytes).Trim()
Dim webAuth As New myWebService.ServiceSoapClient
MessageBox.Show(webAuth.VerifyFeatureSet(serializedData , "", "", "", ""))
how I can accomplish this? If I need to encode the data a different way, include a snippet for decoding it on the far end.
