Whats the proper way to do explicit transactions with linq to sql? -

-

i have scenarios need have multiple calls .submitchanges() on datacontext, want explicitly control transaction myself make atomic. while have been doing creating connection, creating transaction on connection, creating datacontext , passing both. lets assume dont want use transactionscope instead. code looks this:

using conn new sqlconnection("connection string...")    conn.open()    using trans = conn.begintransaction()       dim dc new datacontext(conn)       dc.transaction = trans        ' work         trans.commit()    end using end using

i began using linq sql profiler , breaks code. reason require use .connection property on datacontext create transaction. fails if use connection variable directly (which think silly). question is, more appropriate way:

using conn new sqlconnection("connection string...")    conn.open()    dim dc new datacontext(conn)    using trans = dc.connection.begintransaction()       dc.transaction = trans        ' work         trans.commit()    end using end using

which more accepted way this?

the second snippet doesn't seem appropriate me. second snippet need create transaction after creating context, -at least- readability / maintainability perspective less useful. try imagine how code when need create 2 datacontext classes, , create transaction (only) after creating first context. makes pretty hard keep clean separated code.

i think should send mail hibernating rhinos , ask if fix bug.

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
