now working on registration system, there 3 different scenario users' personal information (name, address e.g.) 1. prepopulate data table1 2. prepopulate data table2 3. empty new user i trying make personal information usercontrol these 3 situation, in case guess need switch determine table go. question worth this? because not sure if client add more scenario in future. thanks yes, in general it's idea follow dry (don't repeat yourself) principle. if you're going present same user interface in 2 (or more) places should attempt code/design once , reuse it. even if presented 1 data source though should attempt decouple presentation model , business logic. it makes code maintenance , testing easier.

i'm researching coding standards cakephp 2.8 project. i'm looking way of handling return values in models. for example in model want return data queried database. want say, "hey found data want , here is" or "sorry couldn't find anything" or "i encountered error while looking data want" so there 3 types of return, data found without error no data found without error an error has occured while looking data any appriciated. why need that? built in a) $data contains data b) empty array (no data found obviously) c) exception being thrown, can either catch or not. so problem doesnt exist in first place imo :)

hiyas. i'm wanting know keys user pressing, press them in delphi app on android (from soft/virtual keyboard). i've got bit of code show keyboard in form's onshow event , wired other code in onkeydown event onkeydown event fired when user presses enter not press each key. do using addtextlistener on jfmxtexteditorproxy of jfmxnativeactivity? work, if have no views/edit controls (just form on i'm rendering image). can assist? tia. daniel. oh dear, long haul. i have code working now. there may still bugs in odd corner cases i've done best test them. in example code, place keys pressed (including enter , delete key presses) tqueue in form , display them in label (one one). adapt code produce events instead. beware of threading issues. to code working, you'll need blank firemonkey application targeting android. place 3 labels on form , name "testkeydownmainform". name unit "formtestkeydownmain". place timer. ...

i'm wondering "standard" way of declaring property in swift is. in particular, seems of apple's swift example code doesn't encapsulate properties (you can freely , set property without having go through getter , setter methods). (i'm used java have trouble believing that's how apple expects developers write code.) right now, have: private var x: int private var xlistener: xlistener? public func getx() -> int { return x } public func setx(newvalue: int) { x = newvalue if (let listener = xlistener) { listener.onxset(x) } } but feel there must simpler way this. saw mention of computed properties seems don't store value, use them you'd have do: private storedx: int public var x: int { { return storedx } set { storedx = newvalue } didset { if (let listener = xlistener) { listener.onxset(storedx) } } } i have trouble believing either of these meth...
