i've inherited ssrs report doesn't work correctly. report meta report of document management system. fwiw, monthly destruction report -- documents destroyed per retention policy. kicker in application there special "stack_location" values represent content status, e.g. 86/86/86 meaning document checked out not returned. given document can have 1 stack location, or 1 special stack location value. the basic query returned appropriate documents. original designer, created filter list excluded special values. intended. however, designer apparently assumed these special value exclusions toggled clicking on radio button in options section. this, of course, not work. indeed, whole approach seems off. i think need default query includes , not in ('86/86/86', '96/96/86'...), somehow optional unions special values. @ sea, however, on how accomplish this. it seems relatively straight forward if using vb, or c#, write different dynamic queries based on v...

i wondering availability of template-typedefs should provide convenience wrappers classes transform types. consider (useless) example: template< t > struct whatever { typedef typename std::conditional< sizeof(t) <= sizeof(void*), int, long >::type type; }; here, std::conditional transform title, used typename transform<...>::type . also, whatever transform , used in same way. with availability of template-typedefs (aka using ), change interface to: template< t > using whatever = typename std::conditional< sizeof(t) <= sizeof(void*), int, long >::type; which simplifies usage. done cases, due required (partial) specialization, end implementation class , wrapper. in case of std::conditional , you'd end moving std::impl::conditional<...> , provide wrapper as namespace std { namespace impl { // "classic" implementation of s...
