I really appreciate your help !

Thank you sooo much :)

It worked from first time ! 

Thank you so much 

Thank you so much.

Creating a list of objects instead of list of a specific type of messages is a good option

Thank you Eduard.

To clarify, I don't have a problem with defining the properties in a message.

My question is how to define a list of messages. What's the syntax ?

Unfortunately, I couldn't find my answer in this documentation.

I want something similar to 

set mylist=##class(%ListOfDataTypes).%New()

But instead of ListOfDataTypes I want List of DoctorInfoMsg

Thanks again :) 

I've stopped the production and I've tried to export but I've faced the same problem

I'm using 2016.2.0.736.0

I'm using Ensemble to export :

I didn't find any owner who's using the reference %Studio.ProjectItem in "view locks" page

I was the only one who's using Ensemble/Studio  with only one session 

Hi Robert,

But I'm using a text file, and I need to send it as it is.

I don't want to send the content of the text line by line.

 classmethod Base64Encode(Text As %String, Flags As %Integer = 0) as %String is used to send strings but not text files.

Thanks
