Hi all,
I need to develop a small but rather advanced email app using vb.net
Up to now everything has been going smoothly until my lecturer asked me to include pictures in the email
I successfully managed to include the picture as attachment but he wanted the picture to be included in the email body itself and not as attachment
Now for 1 image I managed to do it by converting the email into html format and sending it
But now the real problem is when the user wishes to include several pictures in the email
How am i to detect the number of pictures and rewrite the equivalent email html??
I am using a richtextbox for the input of text and pictures
What I managed to do up till now is as follows
Code:Imports System.Net.Mail
Imports System.Net.Mime
Public Class Form1
Dim picturePath As String
Dim pictureExt As String
Dim filePath As String = ""
Private Sub btnSend_Click(sender As System.Object, e As System.EventArgs) Handles btnSend.Click
Dim smtp As New SmtpClient
Dim avHtml As AlternateView
Dim mail As MailMessage = New MailMessage
Dim htmlBody As String
Dim pic1 As LinkedResource
Dim x() As String
x = txtBody.Text.Split(" ")
smtp.UseDefaultCredentials = False
smtp.Credentials = New Net.NetworkCredential("***************", "**************")
smtp.Port = "25"
smtp.EnableSsl = True
smtp.Host = "***********"
Try
htmlBody = "<html> "
htmlBody = htmlBody & "<body> "
If Not x(0) = Nothing Then htmlBody = htmlBody & x(0)
htmlBody = htmlBody & "<br /> "
htmlBody = htmlBody & "<img src='cid:Pic1'> "
htmlBody = htmlBody & "<br /> "
If Not x(1) = Nothing Then htmlBody = htmlBody & x(1)
htmlBody = htmlBody & "</body> "
htmlBody = htmlBody & "</html>"
avHtml = AlternateView.CreateAlternateViewFromString(htmlBody, Nothing, MediaTypeNames.Text.Html)
Select Case pictureExt
Case "jpg", "JPG", "jpeg", "JPEG"
pic1 = New LinkedResource(picturePath, MediaTypeNames.Image.Jpeg)
Case "gif", "GIF"
pic1 = New LinkedResource(picturePath, MediaTypeNames.Image.Gif)
Case "tiff", "tif", "TIFF", "TIF"
pic1 = New LinkedResource(picturePath, MediaTypeNames.Image.Tiff)
End Select
pic1.ContentId = "Pic1"
avHtml.LinkedResources.Add(pic1)
mail.From = New MailAddress("dhanishb@live.com")
mail.To.Add(txtTo.Text)
mail.Subject = txtSubject.Text
mail.IsBodyHtml = True
mail.Body = htmlBody
mail.AlternateViews.Add(avHtml)
If Not filePath = "" Then mail.Attachments.Add(New System.Net.Mail.Attachment(filePath))
smtp.Send(mail)
MsgBox("Email sent!")
txtBody.Text = ""
txtSubject.Text = ""
txtTo.Text = ""
picturePath = ""
pictureExt = ""
filePath = ""
Catch ex As Exception
MsgBox(ex.ToString)
Finally
End Try
End Sub
Private Sub btnAddImage_Click(sender As System.Object, e As System.EventArgs) Handles btnAddImage.Click
Dim openDlg As OpenFileDialog = New OpenFileDialog
Dim filter As String = openDlg.Filter
Dim tmp() As String
Dim img As Image
Dim orgData
openDlg.Filter = "Image File (*.tiff;*.jpg;*.gif)|*.tiff;*.jpg;*.gif"
openDlg.Title = "Open an image file"
If (openDlg.ShowDialog() = DialogResult.OK) Then
picturePath = openDlg.FileName
tmp = picturePath.Split(".")
pictureExt = tmp(1)
img = Image.FromFile(picturePath)
orgData = Clipboard.GetDataObject
Clipboard.SetImage(img)
txtBody.Paste()
End If
End Sub
Private Sub btnAddAttachement_Click(sender As System.Object, e As System.EventArgs) Handles btnAddAttachement.Click
Dim openDlg As OpenFileDialog = New OpenFileDialog
If (openDlg.ShowDialog() = DialogResult.OK) Then
filePath = openDlg.FileName
End If
End Sub
End Class
