wpf - Should I use DTOs as my data models in MVVM? -

-

i'm working on first real foray using mvvm , have been reading various articles on how best implement it.

my current thoughts use data models data transfer objects, make them serializable , have them exist on both client , server sides. seems logical step given both object types collections of property getters , setters , layer in between seems complete overkill.

obviously there issues inotifypropertychanged not working correctly on server side there no viewmodel communicate, long careful constructing our proper domain model objects data models in service layer , not dealing the data models on server side don't think should big issue.

i haven't found info approach in reading, know if pretty standard thing, assumed de facto way of doing mvvm in multi-tier environment? if i've got wrong idea things thoughts on other approaches appreciated too.

i'm no expert on this. had same scenario. agree that quite overkill. i've been using solution quite time , haven't encountered issues. inotifypropertychanged isn't big problem me since nothing on server-side subscribe propertychanged event. if use inheritance on data models, must serializable. in scenario, have 2 base classes data models: 1 used data transfer, , other not.

(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."
