Hello Alexis,

And what data source string do you pass to MakeNewReport method?

RepStrConn="mssql://host='localhost\\SQLEXPRESS' port='1433' dbname='ADG' user='sa' password='1223'"

But you have different host options, try host='localhost‘

Can you connect from VStudio?

Haven't noticed a screenshot at first. So it isn't a connection issue.
Looks like your query contains ORDER BY clause. As it may be nested, for SQL Server it is necessary to define sorting in the report itself, not in the query.

thanks
it work after remove the order by
