How to add a new line in email?

#Caché #ObjectScript

Hi, folks!

I'm sending emails with %Net.MailMessage.

How can I add a new line for the email body?

The code is:

dim msg as %Net.MailMessage = ##class(%Net.MailMessage).%New()
set msg.Charset="UTF-8"
do msg.TextData.Write("Dear  "_Username)
do msg.TextData.Write("Line1")
do msg.TextData.Write("Line2")
And I'm getting in email:

Dear UserLine1Line2

How can I get:

Dear User

Line1

Line2

WriteLine didn't help actually. I'm on Ubuntu, 2017.1. Still getting all in one line. Will try with $C(10).

Yes, the issue was in HTML.

I'm having:

set msg.ContentType = "text/html"

set msg.IsHTML=1

So, <br/> works in this case to make lines like:

do msg.Write("<br/>")

I normally use $CHAR(10), this function represent the ascii character you need

From Class documentation, you can see

property TextData as %FileCharacterStream;

so, you have two methods Write and WriteLine

But anyway even with Write method you can use $c(13) to put line end

my quick test says there are two chars, CR and LF, on an AIX and on Ubuntu

USER>s str=##class(%GlobalCharacterStream).%New()
USER>d str.WriteLine("Test")
USER>d str.Rewind()
USER>zzdump str.Read(100)
0000: 54 65 73 74 0D 0A                                       Test..

Maybe, your problem has nothing to do with Cache?

Maybe you're sending HTML emails?

WriteLine works only for plaintext emails.

Use <br/> for new line in HTML emails.

To send HTML emails specify these settings:

set mail.ContentType = "text/html"
set mail.IsHTML = 1
set mail.Charset = "utf-8"
