access vba - what is the VBA for the USING statement -

in csharp or vb.net use using statement reasons know: 1 can open database , close automatically without writing explicitly. samething in vba

1. how it?
2. are vb.net statement/keywords/ available in vba ?
3. how tell if given statement is(was) known in vba ? there library(glosary) of vba statements/keyword/operators ?

c#

  using(var db=new mydbcontext()){    //do work here   } 

vb.net

    using s = new mydbcontext()      '--..do work here     end using 

answering first question, you've hinted, using syntactic sugar calling dispose() on object instance implements idisposable interface.

it equivalent to

dim s mydbcontext try    s = new mydbcontext()    // ...    s.dispose() end try 

since vba doesn't support using sugar, , in absence of structured try..catch exception handling, you'll need explicitly call dispose() on paths control lifespan of object (mydbcontext in case). in case may have used .close()
