Question:
Hi, I have a VB.NET application in i am trying to send GMAIL mails using the GMAIL OAUTH2 API`s provided on Chilkat. The link which i am following is:
http://www.example-code.com/vbnet/smtp_gmailOAuth2.asp
Now the issue is that, i have everything by the book which is described here but still i am getting this error at the tail end. I wont print the whole Error Log but i think this is the error:
"failed to login using XOAUTH2 method".
The code i am using is this:
Dim iss As String = "********" Dim scope As String = "https://mail.google.com/" Dim sub1 As String = "" Dim numSec As Integer = 3600 Dim accessToken As String = http.G_SvcOauthAccessToken(iss, scope, sub1, numSec, cert) If (accessToken = vbNullString) Then Console.WriteLine(http.LastErrorText) Exit Function Else Console.WriteLine("access token: " & accessToken) End If Dim mailman As New Chilkat.MailMan() ' Set the properties for the GMail SMTP server: mailman.SmtpHost = "smtp.gmail.com" mailman.SmtpPort = 587 mailman.StartTLS = True mailman.SmtpUsername = "retroaa123@gmail.com" mailman.OAuth2AccessToken = accessToken ' Create a new email object Dim email As New Chilkat.Email() email.Subject = "This is a test" email.Body = "This is a test" email.From = "retroaa123@gmail.com" success = email.AddTo("Myself", "retroaa123@gmail.com") ' To add more recipients, call AddTo, AddCC, or AddBcc once per recipient. ' Call SendEmail to connect to the SMTP server and send. ' The connection (i.e. session) to the SMTP server remains ' open so that subsequent SendEmail calls may use the ' same connection. success = mailman.SendEmail(email)
The LastErrorText is :

Any help would be appreciated.
