I'm making a network monitoring program, and the way it works is after five ping-fails, it sends an email, but I cant get it to work! the test email works fine, so its not the email code.
Dim s As Short
Dim newstr(4) As String
Dim I As Integer
Dim name As String
Dim MS As String
[Code] .....
I get the following error:Application-defined or object-defined error.From what I can understand, it's when I attempt to attach a file to the email, I get that error. What I noticed is that it's because the file is in use.Is there anyway to attach the file anyway? My users are simply not closing their files after saving, right now I'm using computer manager to kick them out. The process is for them to save a file on a server through a share and then I pick that up and send it. Works fine as long as they close the file after save.
View 7 Repliesi am trying to ping some terminals and all i could find for code is this
If My.Computer.Network.Ping(IPaddress, 1000) Then
MsgBox(IPaddress & " pinged successfully.")
Else
MsgBox(IPaddress & " request timed out.")
End If
it keeps comming up request timed out message. and i got this from microsoft. instead of a message box i am going to return the response to a listview control but i have to get a successful message first.
I am sending an email with an attachment using the following Code
Dim msg As New System.Net.Mail.MailMessage(req.EmailFrom, req.EmailTo)
Dim att As New System.Net.Mail.Attachment("C:Documents and SettingsmichaelrDesktop1216259.pdf")
With msg
.Attachments.Add(att)
[code]....
The file size of the attachment is 396KB, upon the recipient receiving the email outlook shows the file size as 543Kb. Strange thing is if I send an email with the same attachment using outlook the file size is 396Kb.I understand that file sizes can increase due to the attachment being base 64 encoded as opposed to just raw binary.What I am failing to see is why outlook send a file which is 396KB in size but in code when sending it, the same file is 543Kb.
how would i implement a way that i would not hard code the email message that the application send to email recipients? how will i also include email message formatting (text in bold, italic, etc.)?

I've learned that if you're trying to send mail, you need an SMTP server... I found this list here but every one of them I've tried yields the same "Failure sending mail" error.

mail.To.Add("destination-email@whatever.com")

Is the problem that I need to show "credentials" (i.e. user/pass)? If so, what would those credentials be? Can I use my yahoo email SMTP server with my login info to do it? And is this all I'd need to add to add the credentials?

(before the smtp.Send, of course)

View 1 RepliesMy Regex works, except if the email address entered has an underscore character (_) in it.
Because of my lack of experience with regular expressions, I'm not sure where in my pattern I'm supposed to add the offending character to allow it:
Dim pattern As String = "^[-a-zAZ0-9][-.a-zA-Z0-9]*@[-.a-zA-Z0-0]+(.[-.a-zA-Z0-0+)*." & _
"(com|edu|info|gov|int|mil|net|org|biz|name|museum|coop|aero|pro|tv|[a-zA-Z]{2})$"
He said he fixed it by adding the _ after the numeric check.
I see the A-Z0-9, but I'm not sure which is the numeric check...

I have an application that takes a series of reports and sends them as attachments in an email to a specified group of email accounts.
When I run the Java version of this using apache commons and the same setting, the email is sent. However, when I run the VB.NET version of the code, it fails on my local machine and on the client machine.
I have a VB.NET web application running on a server that uses similar code. I tried that code locally and it fails. Yet, the web application is working perfectly.
Why is it that the Java application can send the email, but the .NET application cannot?[code]....
I have a simple login field, which works fine with the exception of one quirk. The form is set up with the tab order to go to the UserID first and the Password text box second. This works fine when the form is used the first time, but when the form is used the second time the focus in placed in the Password field. If the form is used a third time, focus is moved the OK button, that is each time moves to the next tab order. I even tried to set the focus in the Load event as in Me.txtUserID.Focus(), but this doesn't change the behavior. Again, I should note that I close the form and not hide the form.
