How do I programmatically retrieve SQL Server stored procedure source that is identical to the source returned by the SQL Server Management Studio gui

SELECT

NULL AS [Text],

ISNULL(smsp.definition, ssmsp.definition) AS [Definition]

FROM

sys.all_objects AS sp

LEFT OUTER JOIN sys.sql_modules AS smsp ON smsp.object_id = sp.object_id

LEFT OUTER JOIN sys.system_sql_modules AS ssmsp ON ssmsp.object_id = sp.object_id

WHERE

(sp.type = N'P' OR sp.type = N'RF' OR sp.type='PC')and(sp.name=N'#test___________________________________________________________________________________________________________________00003EE1' and SCHEMA_NAME(sp.schema_id)=N'dbo')
