How to Send A Gmail Email In Vb.net?

4 minutes read

To send a Gmail email in VB.Net, you can use the SMTP client library provided by .NET. First, you need to import the System.Net.Mail namespace in your project. Then, you can create an instance of the SmtpClient class and set the SMTP server and port for Gmail (smtp.gmail.com, 587). Next, set the credentials for your Gmail account using your email address and password. Finally, create a MailMessage object with the sender, recipient, subject, and body of the email, and call the Send method of the SmtpClient object to send the email. Make sure to enable "Less secure apps" in your Gmail account settings to allow access from the VB.Net application.


What is the BCC field used for in Gmail emails in vb.net?

The BCC (Blind Carbon Copy) field in Gmail emails is used to add recipients to an email who will receive a copy of the email without the other recipients being able to see their email addresses. This is commonly used to keep the identities of certain recipients private or to prevent recipients from seeing each other's email addresses. In vb.net, the BCC field can be set using the MailMessage class in the System.Net.Mail namespace.


What is the process for sending emails to a mailing list using Gmail in vb.net?

To send emails to a mailing list using Gmail in vb.net, you can use the Gmail API to programmatically send emails. Here is the process:

  1. Set up the Gmail API in Google Cloud Console:
  • Go to the Google Cloud Console and create a new project.
  • Enable the Gmail API for the project and create credentials for it.
  • Download the credentials file (JSON format) that contains the client ID and client secret.
  1. Add the Gmail API client library to your vb.net project:
  • Install the Google.Apis.Gmail NuGet package in your vb.net project.
  • Add the credentials file to your project directory.
  1. Write the code to send emails to the mailing list:
  • Authenticate the Gmail API using the credentials file.
  • Create a MimeMessage object with the email content.
  • Send the email to each recipient in the mailing list using the Send() method of the UsersResource.MessagesResource in the Gmail API.


Here is a sample code snippet to send an email using the Gmail API in vb.net:

        Dim userId As String = "me"
        Dim scopes As String() = {GmailService.Scope.MailGoogleCom}

        Dim credential As UserCredential
        Using stream = New FileStream(credsFile, FileMode.Open, FileAccess.Read)
            credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
                GoogleClientSecrets.Load(stream).Secrets, scopes, "user", CancellationToken.None).Result
        End Using

        Dim service As New GmailService(New BaseClientService.Initializer() With {
            .HttpClientInitializer = credential,
            .ApplicationName = "Gmail API"
        })

        Dim email As New MimeMessage()
        email.From.Add(New MailboxAddress("Sender Name", "sender@gmail.com"))
        email.To.Add(New MailboxAddress("Recipient Name", "recipient1@gmail.com"))
        email.To.Add(New MailboxAddress("Recipient Name", "recipient2@gmail.com"))
        email.Subject = "Test email"
        email.Body = New TextPart("plain") With {.Text = "This is a test email sent using the Gmail API in vb.net."}

        Dim message As New Message()
        message.Raw = Convert.ToBase64String(Encoding.UTF8.GetBytes(email.ToString))
        service.Users.Messages.Send(message, userId).Execute()

        MessageBox.Show("Email sent successfully.")
    End Sub
End Class


Note: Make sure to replace the actual values with your own Gmail credentials and mailing list recipients. Also, handle exceptions and error checking in your code to ensure the email is sent successfully.


How to schedule email sending using Gmail in vb.net?

To schedule an email sending using Gmail in VB.NET, you can use the Gmail API to authorize your application to send emails on behalf of a user. Here's a step-by-step guide on how to do it:

  1. Create a project on Google Cloud Platform:
  • Go to the Google Cloud Platform Console: https://console.cloud.google.com/
  • Create a new project and enable the Gmail API for that project.
  • Create OAuth 2.0 credentials for your project and download the JSON file containing the client ID and client secret.
  1. Install the Google.Apis.Gmail.v1 NuGet package:
  • In Visual Studio, right-click on your project and select Manage NuGet Packages.
  • Search for Google.Apis.Gmail.v1 and install it.
  1. Authenticate with the Gmail API:
  • Use the following code to authenticate with the Gmail API using the client ID and client secret from the JSON file:

Dim credential As UserCredential
Using stream = New FileStream("path/to/client_secret.json", FileMode.Open, FileAccess.Read)
    credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
        GoogleClientSecrets.Load(stream).Secrets,
        New String() {GmailService.Scope.MailGoogleCom},
        "user",
        CancellationToken.None).Result
End Using
Dim service = New GmailService(New BaseClientService.Initializer() With {
    .HttpClientInitializer = credential,
    .ApplicationName = "YourAppName"
})


  1. Schedule the email sending:
  • Use the following code to schedule an email to be sent at a specific date and time:

Dim mailMessage = New Google.Apis.Gmail.v1.Data.Message()
Dim rawMessage = "From: sender@example.com" & Environment.NewLine & "To: recipient@example.com" & Environment.NewLine & "Subject: Test Email" & Environment.NewLine & "Hello, this is a test email sent using the Gmail API!"
mailMessage.Raw = Convert.ToBase64String(Encoding.[Default].GetBytes(rawMessage))

Dim sendDate = DateTime.Now.AddMinutes(1) ' Send email in 1 minute
Dim timeToSend = sendDate.Subtract(New DateTime(1970, 1, 1, 0, 0, 0))
Dim timestamp = Convert.ToInt64(timeToSend.TotalMilliseconds).ToString()

Dim message = service.Users.Messages.Send(mailMessage, "me").Queue("me", timestamp).Execute()


  1. Run your application:
  • Run your VB.NET application and the email will be sent at the scheduled date and time.


Note: Make sure to handle exceptions, check for errors, and handle rate limits when using the Gmail API.
