A client for our company contains an apostrophe in their email name joe's@joe.com. I was advised that this is the correct and current email for the given client. Below is the Expression string I am using with Regex (which I copied from the internet somewhere) to validate email addresses. How can this expression be modified to allow/accept apostrohe's?
strRegex =
"^([a-zA-Z0-9_-.]+)@(([[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.)|(([a-zA-Z0-9-]+.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(]?)$"
im using vb8.net im struggling to make a program that will display email addresses so in other words if im using ms outlook then by the click of the button the program must go in to the windows registry and then look in the place where the email address is and then read that part and display the address in a text box.
View 8 RepliesI have created an application and I need to send emails to different addresses. I want to do this inside my application without automating email software like outlook etc. I have used CDO , and different activex like ostrosoft , chilkat etc .But is the same problem : Emails are sended correctly without error messages but :Some emails are received ( like in yahoo adresses), a lot of emails are marked as spam, and all the emails send to hotmail addresses are lost, not received. To send emails I'm using a regular domain, with smtp server, port, user name and password. And when I send emails from the same configuration on outlook express from the same computer, all the emails are received correctly.

I have a simple email.aspx page that has From:, To:, Subject:, and Body: text boxes. The send button is set to send the email using smtp through System.Net.Mail in ASP.NET 4.
What I'm really trying to do is set the To: address to automatically retrieve all of the email addresses stored in my SQL database table that my customers entered when they registered for updates from my websites, rather than me type each one in by hand. I am wanting it completely automated without any user interaction.
I have looked everywhere for weeks to try to get help and I can't seem to find anything describing what I am trying to do.
I am trying to send email messages to multiple email addresses from a listbox. Here is my code -
For i = 0 To lstbxEmailAddress.SelectedItems.Count - 1
If EmailAddressTo = "" Then
EmailAddressTo = CType(lstbxEmailAddress.SelectedItems(i), DataRowView).Item("EmailAddress")
[Code]...
I am able to get the email addresses stored in the variable EmailAddressTo separated by a comma in between addresses. However, it only sends to the first email address. I selected two addresses but it only sent to the first address. How can I add multiple addresses using the To.Add method?
Is it possible to detect email addresses entered in richtextbox and when clicked then redirect to compose message of local mail to that email address.

Is there a way in VB.Net to "Ping" an email address to see if that email is a real one that does not give any errors?
If yes, can you show what the VB.Net coding looks like to implement this?
I plan to use this in an app that requires the Customer email and it would be nice to validate it as the call taker enters it into a form before saving the Customer details.
Here is the code we are using to send an email promotion to all of the customers in our customer table:

Dim SmtpServer As New SmtpClient()

View 1 RepliesI have the following text that I am trying to parse:
"user1@emailaddy1.com" <user1@emailaddy1.com>, "Jane Doe" <jane.doe@ addyB.org>,
"joe@company.net" <joe@company.net>
I am using the following code to try and split up the string:
Dim groups As GroupCollection
Dim matches As MatchCollection
Dim regexp1 As New Regex("""(.*)"" <(.*)>")
matches = regexp1 .Matches(toNode.InnerText)
For Each match As Match In matches
groups = match.Groups
message.CompanyName = groups(1).Value
message.CompanyEmail = groups(2).Value
Next
But this regular expression is greedy and is grabbing the entire string up to the last quote after "joe@company.net". I'm having a hard time putting together an expression that will group this string into the two groups I'm looking for: Name (in the quotes) and E-Mail (in the angle brackets).
I have taken an interest in creating a SMTP server in vb.net that has the ability to hide ip addresses in email headers.I see that some people claim that it's possible around on the internet, but I haven't seen any direct source code to create an anonymous smtp server in visual basic 2008.Now I know that it's legal to send emails via a masked ip address and I believe that it's also fair since some people believe in anonymity, but I am in all means against spammers.
View 2 RepliesI have a list of directories that get files added to by other users on my network.I would like a script (triggered by scheduled task) that would detect if there are files in these folders older than 15 minutes, and send me an email. I am able to run Batch/DOS, Python, Perl, or VBS - I have them all installed on the server. As long as they can be triggered from Scheduled task.
Example:
C:UsersFTPJoeSFromCustomer <files dropped here>
C:UsersFTPMarkFromCustomer <files dropped here>
C:UsersFTPRobbieFromCustomer <files dropped here>
C:UsersFTPTammyFromCustomer <files dropped here>

I got help with pinging a range of IPs earlier and was given this code. I was then trying to change it slightly so I could scan more than my network between any given range e.g. 125.1.1.1 to 126.12.25.66.[code]
View 3 RepliesI have a list of machines, 1 per line in a file called devices.txt.
What I need to be able to do is to ping each of these machines, and then output each machine that is online to another text file called machines.txt
The files need to just be the machine name and have 1 machine per line.
I want a start IP and end IP and it to ping all the IPs between and including those IPs. I've seen examples of when it gets the subnet and then iterates through from 0 to 255 but I'm struggling with this. Is there a way to make an IP address object (is this the right word?) that iterates the same way as an IP would e.g.goes from 192.168.1.255 then would go to 192.168.2.0.

View 6 RepliesI've run into a bit of a problem using Async ping. Basically, I want to ping computers in the list before I run the next bit of my program. The computers who I can ping are added to a list and that is used in a background worker. Trouble is can't seem to work out how to wait until after pinging ALL computers in the list, either successful or timed-out. Is there something a long the lines of 'If Async Ping is running'?
Private Sub pingCompleted(ByVal sender As Object, ByVal e As System.Net.NetworkInformation.PingCompletedEventArgs)
If e.Reply.Status = Net.NetworkInformation.IPStatus.Success Then
complist.Add(e.UserState)
Else

End If
End Sub
I need the next bit to wait because if 'complist' is changed while it's being used I get collection errors.
I have a class that uses My.Computer.Network.Ping to get a boolean value on whether a IP address or hostname is reachable.However, when I'm testing that class, I want to disable pinging so that during the test whenever I run the My.Computer.Network.Ping it will always return false or throw some kind of exception.
I have tried the following, but I still get a true returned (meaning, the attempts to disable ping didn't work)
Dim restricited As New System.Net.NetworkInformation.NetworkInformationPermission(System.Security.Permissions.PermissionState.None)
Dim mySocketPermission1 As New SocketPermission(PermissionState.None)
Dim myWebPermission As New WebPermission(PermissionState.None)

View 1 RepliesIve got an app that holds a list of site we have, At each site there are a few devices. The idea is when they click on a site all the details for the site are loaded and then a second thread sits and pings each device to see if its live. Im trying to do this in a seperate thread so if they click another site while its still pinging them it doesn't wait before it switches site. This all seems to be workling fine except if you click through the sites quickly, when you do that it will eventually come up with
