I use a Next and Previous button to make 1 of 10 text files visible in EditText3, the Message.Body of an email.
We can change the visibility of an EditText view in Designer or using a btn_Click, is there a way to do this to the email client because I only want the To: and Subject: boxes visible?
Message.Body = EditText3.Text 'message body content
Message.Body.Visible = "False" 'Does not work.
No. You don't have control on the mail app. You can use SMTP from the Net library to send the mail yourself (though you will need to ask the user for his password).
