A SQL reporting services report definition has loads and
loads of properties. One of these is the visibility of a table (the
core of a report) or subreport. Also here you can
use a vbscript
expression to set the property. I don't know if it is a bug or a
feature, but the subreport (or table) will show when the expression is
evaluated as
false. When it is a feauture I think the property has the
wrong name, when it's a bug it is a bug. Confusing.
