为什么没有Tp怎么连接SQLite数据库？？？（转）

摘自：http://www.phpfans.net/ask/MTIzOTk2OA.html

我非常喜欢thinkphp，但是刚开始学习thinkphp，有些地方还不太熟，请高人指点！
最好能给个例子！

谢谢！！

官方不可能给每个数据库驱动给出代码示例，具体在使用的时候有什么错误提示可以明确提出。

我是用TP连接SQLite数据库，数据库里的内容读出来了，但是在网页的最下面出现一个错误，
Fatal error: Exception thrown without a stack frame in Unknown on line 0
------------
不知道怎么解决？？？

配置
return array(
    'DB_TYPE'=>'sqlite',
        'DB_NAME'=>'Mayi_db/CMS.sdb',
        'DB_PREFIX'=>'CMS_',
        );

读取
$test=M('Admin');
$list1=$test->findAll();
dump($list1);


模型
class AdminModel extends Model{

    function AdminModel() {
    }
}

-------------------------
请高手指点！！！！！

config.php中sqlite参数如下：
        'DB_TYPE'=>'sqlite',
        'DB_NAME' => 'demo2.sqlite',
        'DB_PREFIX'=>'',
-----------------------
Fatal error: Exception thrown without a stack frame in Unknown  on line 0
上面错误出现，是由于DBsqlite.class.php中的public function close这个函数的原因，sqlite_close（）方法没有返回值，所以，无论数据库连接是否关闭，if中的报错都会执行。
将if中sqlit_close()前的叹号去掉就可以了。当然，也可注释掉if中的报错code

flex中将图片保存成xml文件存入本地（转）

我们知道Flex对于本地的限制比AIR要大，当我们想保存一个由Flex生成的文件必须借由服务器来完成，现在有一个需求就是，用户想保存Flex生成 的图片在本地，我们要完成这个过程，必须先将Flex生成的图片转换为通用的数据格式，即ByteArray，然后由后台程序帮助写文件，形式上类似先上 传，再下载，只不过中间不用保存实际的物理文件。
