I am trying to send a mail to more than one person at a time.
My code is like this;
Dim SmtpServer As New SmtpClient()
SmtpServer.Credentials = New Net.NetworkCredential("jasibs002#gmail.com", "someMadeUpPassword")
SmtpServer.Port = 25
SmtpServer.Host = "smtp.gmail.com"
SmtpServer.EnableSsl = True
Dim omail As New MailMessage()
omail.From = New MailAddress("jasibs002#gmail.com", "JaseemBinBacker", System.Text.Encoding.UTF8)
omail.Subject = "Test Mail"
Dim str As String
str = "Hai How Are You I am Sendig This Mail for Testing"
str = str + vbNewLine & "Checking"
str = str + vbNewLine & "Sucess"
omail.Body = str
Dim email As String
Dim cmdemail As New SqlCommand("SELECT Emailid FROM dbo.Email_tbl", con.connect)
dr = cmdemail.ExecuteReader
While dr.Read
email = dr("Emailid")
omail.To.Add(email)
End While
dr.Close()
con.disconnect()
SmtpServer.SendAsync(omail, Nothing)
Catch ex As Exception
MsgBox(ex.ToString)
End Try
While executing this, I am getting the following error;
An asynchronous call is already in progress. It must be completed or canceled before you can call this method.
My Email Table has more than 10 email ids.
Change your While loop to:
While dr.Read
email = dr("Emailid")
omail.To.Add(email)
End While
SmtpServer.SendAsync(omail, Nothing)

I am trying to make a ConsoleApplication attach all files in a folder to an email and send it. I know how to do it with a single attachment, but for the life of me, I cannot figure out how to attach all items in a folder.
Current code:
Sub Main()
Try
Dim mail As New MailMessage("from", "to")
Dim client As New SmtpClient()
client.Port = 25
client.DeliveryMethod = SmtpDeliveryMethod.Network
client.UseDefaultCredentials = False
client.Host = ""
mail.Subject = "" + DateTime.Now.AddDays(-1).ToShortDateString()
mail.IsBodyHtml = True
mail.Body = "Test"
Dim file As System.Net.Mail.Attachment
file = New System.Net.Mail.Attachment("Path to single file")
mail.Attachments.Add(file)
client.Send(mail)
Return
Catch [error] As Exception
MsgBox("error")
Return
End Try
End Sub
Thanks in advance
EDIT:
I tried the below code that I found on another post, but it just errors out (and using the ConsoleApplication, I am not sure how to view the exact error its giving)
For Each filePath As String In Directory.GetFiles(My.Settings.FileLoc1)
Dim Attach As New Net.Mail.Attachment(filePath)
mail.Attachments.Add(Attach)
Next
I got it working!
Sub Main()
Try
Dim mail As New MailMessage("from", "too")
Dim client As New SmtpClient()
client.Port = 25
client.DeliveryMethod = SmtpDeliveryMethod.Network
client.UseDefaultCredentials = False
client.Host = ""
mail.Subject = "" + DateTime.Now.AddDays(-1).ToShortDateString()
mail.IsBodyHtml = True
mail.Body = "Test"
For Each filePath As String In Directory.GetFiles(My.Settings.FileLoc1)
Dim Attach As New Net.Mail.Attachment(filePath)
mail.Attachments.Add(Attach)
Next
client.Send(mail)
Return
Catch [error] As Exception
MsgBox("error")
Return
