メーラを起動する

メーラ(Outlook)を起動してアドレス、本文を埋め込むプログラムは以下の通り。

Public Class _Default
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    End Sub

    Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim sMailAdr As String = "hoge@hoge.co.jp"
        Dim sMailCc As String = "hogeCc@hoge.co.jp"
        Dim sMailBcc As String = "hogeBcc@hoge.co.jp"
        Dim sSubject As String = "【件名】"
        Dim sBody As String = "本文" & "%0d%0a" & "以上です。"


        ' VB.NET
        Process.Start("mailto:" & sMailAdr & "?cc=" & sMailCc & "&bcc=" & sMailBcc & "&subject=" & sSubject & "&body=" & sBody)

    End Sub
End Class

本文に改行を入れる場合はエスケープシーケンス"%0d%0a"を用いること
