我有以下json对象,我需要通过javascript提醒它.

{data:[{"empmenuid":"1","empid":null,"deptid":"66","aliasid":"66","firstname":"66","lastname":"66","sin":"66","status":"66","empclass":"66","hiredate":"66","seneoritydate":"66","separationdate":"66","recalldate":"66","martialstatus":"66","gender":"66","ethinicorigin":"66","ethinicsuborigin":"66","nationality":"66","address1":"66","address2":"66","city":"66","province":"66","postalcode":"66","country":"66","email":"66","officialemail":"66","phone":"66","otherphone":"66","fax":"66","officephone":"66","officeext":"66","officefax":"66","mobilephone":"66","pager":"66","locid":"66","jobtitle":"66","jobtitlestart":"66","fullpart":"66","manager":"66","managername":"66","middlename":"66","nickname":"66","paytype":"66","payfreq":"66"},{"empmenuid":"3","empid":null,"deptid":"12","aliasid":"12","firstname":"12","lastname":"12","sin":"12","status":"12","empclass":"12","hiredate":"12","seneoritydate":"12","separationdate":"12","recalldate":"12","martialstatus":"12","gender":"12","ethinicorigin":"12","ethinicsuborigin":"12","nationality":"12","address1":"12","address2":"12","city":"121","province":"12","postalcode":"12","country":"12","email":"12","officialemail":"12","phone":"12","otherphone":"12","fax":"12","officephone":"12","officeext":"12","officefax":"12","mobilephone":"12","pager":"12","locid":"12","jobtitle":"12","jobtitlestart":"12","fullpart":"12","manager":"12","managername":"12","middlename":"12","nickname":"12","paytype":"12","payfreq":"12"}],
recordType : 'object'}

我想提供注释与一些方法生成的一些值.

到目前为止我试过这个:

public @interface MyInterface {
    String aString();
}

@MyInterface(aString = MyClass.GENERIC_GENERATED_NAME)
public class MyClass {

    static final String GENERIC_GENERATED_NAME = MyClass.generateName(MyClass.class);

    public static final String generateName(final Class<?> c) {
        return c.getClass().getName();
    }
}

思想GENERIC_GENERATED_NAME是static final,它抱怨说

注释属性的值MyInterface.aString必须是常量表达式

那么如何实现呢？

我需要计算值范围内的记录.

例如:对于集合 1, 7, 9, 23, 33, 35, 1017

select count(myvalue) group by round(myvalue / 10) 给出类似的东西:

0-10  -> 3
10-20 -> 0
20-30 -> 1
30-40 -> 2
1010-1020 -> 1

这很好用.但是,我需要设置一个上限,以便MySQL返回40+ --> 1？怎么能实现这一目标？

我该如何覆盖UserControl Visible属性？或者如何在控件内确定何时更改其Visible状态？

稍后编辑:我需要它在.NET CF 3.5中工作.

谢谢.

有人可以告诉我如何在Windows Mobile下使用C#将byte []转换为ArrayList？

稍后编辑:

1. 这就像拥有一个包含自定义类型实例的ArrayList.此列表作为字节数组转发到数据库(转换为blob)(转换由数据库API完成); 我想要的是将byte []还原为ArrayList;

2. .NET CF不提供BinaryFormatter;

我有一个基于UDP Netty的服务器.它有一个SimpleChannelUpstreamHandler流水线,我覆盖了该messageReceived方法.

我需要不时地回复一些信息.我只能通过使用来自的套接字信息MessageEvent.getRemoteAddress()和来自的通道来实现MessageEvent.getChannel().为了能够重用这些信息,我将其保存在静态地图中.

这变成了 MessageEvent.getChannel().write("foo", MessageEvent.getRemoteAddress());

我所期望的是有MessageEvent.getChannel().getRemoteAddress()工作,但事实并非如此.它总是给我null.

1. 难道我做错了什么 ？
2. 是否有更好的回写方式,而不是将频道和远程地址保留在某个成员中？

我扩展了PictureBox并创建了一个单例.

是否可以在两个不同的窗体上同时显示PictureBox控件的相同实例？

提前致谢.

给出以下代码:

Hashtable main = new Hashtable();

Hashtable inner = new Hashtable();
ArrayList innerList = new ArrayList();
innerList.Add(1);
inner.Add("list", innerList);

main.Add("inner", inner);

Hashtable second = (Hashtable)main.Clone();
((ArrayList)((Hashtable)second["inner"])["list"])[0] = 2;

为什么数组中的值在"main"Hashtable中从1变为2,因为更改是在克隆上进行的？

谁能告诉我一个方法来防止SQL注入用于建立查询时SQLite,其中WHERE子句的"myval IN (string_1, ... , string_n)"条件？

我想通过注释动态构建命令文本,并从字符串列表中添加这些注释的参数.有没有更简单的方法 ？

谢谢.
