我想知道哪个更快:XML和JSON？什么时候使用哪一个？

我正在通过后台服务发出通知.在通知中我正在显示图像,图像尺寸为15*15.但是当显示图像时,它会自动拉伸到大尺寸,因此变得模糊.我没有在程序中指定图像大小.为什么会这样

我在按钮点击时使用jQuery来实现滑块效果.我的代码是:

$(document).ready(function() {

  $("#mybutton").click(function () { 
      $("#slidemarginleft").hide("slide", { direction: "down" }, 1000);
});
});

当我单击按钮时,会发生JavaScript错误:

f.easing[e.animatedProperties[this.prop]] is not a function

我想创建一个聊天应用程序,其中有一个ComboBx.我想用网络中的所有计算机名称填充它.我怎样才能在C#中实现这一目标？

我正在WPF中创建一个类似于应用程序的记事本.我想根据屏幕尺寸设置窗口高度和宽度.如何获得屏幕高度和宽度？

create or replace trigger insert_test_id
before insert on test
where(test.name='Ash')
begin
insert into test(s_no) values('def');
end

我的桌子是

test id整数名称varchar2(200)s_no varchar2(250)

请告诉我这个触发器的错误是什么.我无法找到答案.

我想在ArrayList中添加String和Integer类型的值.

例如,我有一个数组列表,其中我想在单个集会中添加人员的姓名和相应人的年龄.

我怎样才能做到这一点.我怎么能得到这个？实际上我正在从数据库中检索数据,并希望将所有员工姓名和年龄保存在单个数组列表中.像多维数组列表.

<RichTextBox AcceptsTab="True" ForceCursor="True" IsDocumentEnabled="True" TextChanged="ContentChanged" Name="TextContent"/>

在 C# 文件中，我无法获取 Rich Textbox 的 Text 属性。我试图得到这个；

TextContent.Text= "hello"

但它给出了编译时错误。

'System.Windows.Controls.RichTextBox' does not contain a definition for 'Text' and no extension method 'Text' accepting a first argument of type 'System.Windows.Controls.RichTextBox' could be found (are you missing a using directive or an assembly reference?) 

请建议我。

我是Android的初学者.尝试在操作栏中添加搜索小部件.这是我的菜单文件代码("main_acitivity.xml"):

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
    <!-- Search, should appear as action button -->
    <item android:id="@+id/action_search"
          android:icon="@drawable/ic_search"
          android:title="@string/action_search"
          android:showAsAction="always"
          android:actionViewClass="android.support.v7.widget.SearchView" />
    <!-- Settings, should always be in the overflow -->
    <item android:id="@+id/action_settings"
          android:title="@string/action_settings"
          android:showAsAction="never" />
</menu>

我的MainActivity类代码是:
