Question

I have a simple textbox with an email address.

I need to know the best and easiest way to find out whether that email address is valid or not. I want to know how I can do that.

I have tried using the below code but it does not display any message for me? Can anyone point the mistake I am making?

Public Function IsValidEmailAddress(ByVal email As String) As Boolean
    Try
        Dim ma As New MailAddress(email)
        MsgBox(True, MsgBoxStyle.Information)
    Catch
        MsgBox(False, MsgBoxStyle.Information)
    End Try
End Function

I am calling this function like this:

Call IsValidEmailAddress(txtEmail.txt)

Answer 1

Assuming that your call code is not a typo, the problem is you are not using the correct property:

Call IsValidEmailAddress(txtEmail.txt)

should be:

Call IsValidEmailAddress(txtEmail.Text)

I have verified that the IsValidEmailAddress works correctly.
