我在WP7工作.我需要将JSON数组值解析为列表框.有人说,使用Serializer和Deserializer,但我不知道如何使用serilizer和反序列化器将这些值解析为组合框或列表框？
我有一个key.bin文件,其内容类似于:
-12, 110, 93, 14, -48, ...
服务使用它来解密3DES内容,但我需要通过Ruby加密它.
我已经尝试了大量的场景,如何设置密钥以及如何处理它,但是到目前为止无济于事:
我认为我需要做的事情很简单:
des = OpenSSL::Cipher::Cipher.new('des3')
des.decrypt
des.key = mistery # this step is where i'm having problems at
final = des.update(encrypted) + des.final
关于我应该用这个键做什么的任何想法？
关键样本:
-62,-53,124,-110,37,-88,-48,31,-57,93,70,-101,44,69,-88,-57,-123,-99,118,-119,110,55,11,14

代码是
HttpClient client = new DefaultHttpClient();
String postURL …例如,像......
// get everything that is either an input or a select
$container.find(':any(input, select)');
是否有代码示例或有关如何使用该Thread.setDefaultUncaughtExceptionHandler方法的教程？基本上我在我的应用程序中尝试在抛出异常时显示自定义警报对话框.是否有可能做到这一点？我知道在屏幕上显示某些内容有点棘手,如果在UI线程中抛出异常,但我不知道任何解决方法.

## Major …是否有任何价值以外 False,None,0,并且0.0将返回False用bool(x)(在Python 3.X)？
我目前有一个转发器控件,在itemtemplate里面我有一个usercontrol.此用户控件正确呈现,但我尝试将数据项分配给转发器控件中的属性.
<asp:Repeater ID="Repeater1" DataSourceID="EntityDataSource" runat="server">
<ItemTemplate>
<uc1:Request ID="Request1" runat="server" RequestId='<%# Eval("RequestId") %>' />
</ItemTemplate>
RequestId只是一个Int32.它只是没有分配它.
我可以将eval放在usercontrol之外,只是在itemtemplate中它正确输出正确的id.
如果我删除整个eval并只输入一个数字,那么它可以正常工作.
任何帮助赞赏.
[更新]:问题已解决
我使用的是EntityDataSource,它会自动绑定到转发器.它在屏幕上打印出数据库中的所有信息,没有任何代码隐藏.但是当我把代码放在Repeater1.DataBind()之后; 然后开始工作.
我不知道为什么,但嘿,它已经解决了.它现在成功传递了价值.我想它与页面生命周期有关.
