網路看到的笑話幾則

一對夫妻在蜜月旅途中....車突然拋錨~
男下車修理~搞了老半天都弄不好~
女:天色漸晚了耶~前面有家汽車旅館~我們過去那裡休息~說不定跟上次 一樣~睡一覺後車子就會好了~
男:那次是結婚前好不好~這次是真的車子壞了!!!

一女從計程車下車，司機突然從車里探出頭：小姐，你像雞！
女臉一紅，罵到：你他X的像隻鴨。
司機聽了不爽,然後就快速開走了。








然後女孩突然想起追著車喊：運將，我相機，我相機！

廣東一夥劫匪在搶劫銀行時說了一句至理名言：“通通不許動，錢是國家的，命是自己的！”
大家一聲不吭躺倒。
劫匪望了一眼躺在桌上四肢朝天的出納小姐，說：“請你躺文明些！這是劫財，又不是劫色！”
劫匪回去後，其中一個新來的碩士劫匪說：“老大，我們趕快數一下搶了多少錢。”
那老劫匪（小學畢業）說：“你傻啊？這麼多，你要數到什麼時候啊？今天晚上看看新聞不就知道了嗎。”

——這就叫工作經驗，這年頭工作經驗比學歷更重要！！！

劫匪走後，行長說，趕緊報案！
主任剛要走，行長急忙說：“等等！把我們上次私自挪用的五千萬也加上去！”
主任會意，陰笑道：“要是劫匪每個月都來搶一回就好了。”
第二天，新聞聯播報導銀行被搶了七千萬。
劫匪數來數去只有兩千萬。
老大罵道：“媽的，老子拼了一條命才搶了兩千萬，銀行行長動動嘴皮就賺了五千萬，看來這年頭還是要讀書啊！

父：膽子好大，我長這麼大從未看過。
機器人隨即給其父一巴掌。

Flex3 Localization

http://www.herrodius.com/blog/123


1. create a folder in your project src to store your resource bundles (e.g. "locale")
2. create a subfolder for each locale you want to implement (e.g. "locale\en_US" and "locale\zh_TW")
3. in the locale subfolder, create a resources.properties file and save it as UTF-8
4. enter the resources in the form of "key=value", like Ant property files
example:

   # locale/en_US/resources.properties
   login_id=id
   password=password

5. update the compiler settings: -locale=en_US,zh_TW -source-path=locale/{locale}

  [ResourceBundle("resources")]



< mx:FormItem label="{resourceManager.getString('resources', 'login_id')}" ....

switch your locale at runtime by setting the localeChain property on the resourceManager:

resourceManager.localeChain = ["en_US"];
//resourceManager.localeChain = ["zh_TW"];

Set focus on textfield in Flex3

In Action Script:
login.setFocus();

In HTML:

< body onload="setFlexAppFocus();">

   

2. detect press Enter

   

   /**
   * Handle login when user press enter on password
   */
   private function enterListener(e:KeyboardEvent):void {
       if(e.keyCode == Keyboard.ENTER) {
           enter(); // check login function
       }
   }
