Sharetronix微薄系统中访问mysql数据库类，支持mysqli，还是非常好用的。基本直接就可以用。

支持DEUBG模式。如果将DEBUG设置为true，则可以通过get_debug_info()

获得调试状态下的信息。

Flex4中的一个简单的StringValidator验证和HTTPService

2010-06-08T15:17:00Z

输入用户名和密码，进行长度和必填项验证，验证成功后提交给php处理，返回提交的该值，主要用了两个点

1.StringValidator 的一个简单应用

2.HTTPService 与Php的一个交互

Flex4中使用Halo皮肤外观

2010-06-06T03:12:00Z

发现Spark的皮肤没有halo皮肤漂亮，但是选择halo的主题以后竟然无效。

去网上搜索了一下，发现很多人都想使用Halo的外观，虽然有答案，但是几经应用不成功，所以自己重新建立项目的时候发现，

在完成项目最后一步之前，库路径的TAB下面，有个组件集->MX+Spark 仅MX ,默认的是选的前者，这里只需要选择后面

这个仅MX就可以了。之后建出来的项目就是 Halo 的主题。

下面这段是网上的解决办法，但是本人未成功

Flex4中的State切换

2010-06-05T04:43:00Z

简单的功能描述：

1.一个用户登录界面，点击忘记密码以后切换到忘记密码状态

2.在忘记密码界面点击返回登录后切换到登陆画面

功能很简单，和Flex3有很大的区别，所以做一个记录

Flex中的Timer类的一个例子和一些说明

2010-06-02T18:27:00Z

功能说明：

点击按钮获得验证码，之后按钮失效，1分钟后可以再点击，先看下代码

   private var timer:Timer;
            private var pointer:Number = 60;
            private function setBtnEnableTime():void{
                timer= new Timer(1000);//时间间隔为1秒钟
                timer.addEventListener(TimerEvent.TIMER, setGetCodeBtnEnable);
                timer.start();
            }
            private function setGetCodeBtnEnable(event:TimerEvent):void{
                this.pointer -= 1;
                btnGetCode.label = "获取验证码["+pointer+"]";
                if(this.pointer==0){
                    timer.stop();
                    btnGetCode.label = "获取验证码";
                    btnGetCode.enabled = true;
                    this.pointer = 60;
                }
            }

主要看下红色字体部分，这里的setGetCodeBtnEnable这个方法是有参数的为 TimerEvent，在引用名称空间的时候不要引用错了，

是 import flash.events.TimerEvent; 名称空间下的。

如果这个是没有参数的方法，会提示应有参数为1个，实际0个的错误。

在添加一些监听的时候，调用的方法都要加上一个默认的参数，否则会提示参数个数的问题，需要注意一下。

收藏一个Php的Cache类

2010-04-14T14:53:00Z

Cache的作用不用说大家都知道咯,这些天也面试了一些人,发现很多人框架

用多了,基础都忘记了,你问一些事情,他总是说框架解决了,而根本不明白

是怎么回事,所以也提醒大家应该注意平时基础知识的积累,之后对一些问

题才能游刃有余.

群里也有些朋友对基础知识很不屑,总说有能力就可以了,

基础知识考不出来什么.对于这样的观点,我一直不苟同.

这个只是一点感概罢了. 下面看正题,介绍一个php的Cache类:

All the code here is covered by the PHPGuru license. A short summary is that for any sort of commercial use there is a small one-off licensing fee to pay, and for charity and educational use there is a reduced license fee.

You can read more about licensing here (where there's also a link to Google Checkout).

贴一下代码吧:下面也有下载地址，其实很简单，重要的是学习

J2me使用第三方模拟器KEmulator配置

2010-03-03T04:03:00Z

1.将项目作为Java Application程序来运行
2.参数配置
（1）Main选项卡下：Project=》名字，Main Class=》emulator.Emulator
（2）Arguments选项卡：参数的具体内容自己根据实际情况来
   -device "SonyEricssonK800"
   -midlet you.XXXMidlet           //程序的入口
   -cp "bin"
   -jad XXXX.jad
（3）classpath选项卡下：
   先把里面的全部remove，之后再User Entries下面添加如下内容
   点击advanced按钮，选择项目中的res和src文件夹，确认
   点击Add External jar按钮，添加KEmulator.jar文件，确认
（4）run
3.需要KEmulator的模拟器包

KEmulator是可以自己手动调节分辨率，非常方便，估计KEmulator_0.9.8这个可以找到下载地址
