VB.net 2010 how to send a email without having the user open outlook

Dear Experts,

Cant I get around this if so can you please enlighten the path for me?

This is what I have so far it works but user has to accept message (see attached)

Is there a way around this prompt?

 Dim olApp As Outlook.Application
        Dim olMail As Outlook.MailItem
        olApp = New Outlook.Application
        Try

            ' WORks but requires outlook to be open and user to accept

            ' Create a new MailItem.
            olMail = olApp.CreateItem(Outlook.OlItemType.olMailItem)
            olMail.Recipients.Add("test@test.com")
            olMail.Subject = "IMPORT SUMMARY"
            olMail.HTMLBody = "Attached  are Imported Files and Error Messages!!"""
            olMail.Attachments.Add("C:\test.txt", Outlook.OlAttachmentType.olByValue)
            olMail.Send()
            '
        Catch ex As Exception
            MessageBox.Show("Error File Import" & ex.Message)
            Dim mylogfilefile As System.IO.StreamWriter
            mylogfilefile = My.Computer.FileSystem.OpenTextFileWriter("c:\test.txt", True)
            mylogfilefile.WriteLine("" + ex.Message)
            mylogfilefile.Close()
        End Try
