最近在弄一个数据库相关的东西,
一个是如果有大批量的loop动作写入一个庞大的表的话,不采用事务将导致及其缓慢的IO延迟和性能的损耗,但是如果用数据库事务将大大的提升执行效率和性能;
对于数据库,尤其是存储过程中加入set nocount on的话,数据库将不会把done_in_proc这类的消息发送给客户端,这将显著的提升执行性能(因为减少网络传输流量)。

104.使用JS加载图片的问题(在IE6(IE6.2900.5512以前版本都有这个问题))
代码
原先脚本代码:
//
IE6 加载无显示(其他OK)
$(
"
#photoShow
"
).empty().append($(pic).html()).show();
解决方案:
原因:IE6 BUG
描述:dom.innerHTML
=
""
这种方式赋值时,如果有资源文件,IE6不会从缓存里读而是重新请求一遍。。
但请求过程中会大概率丢失。。
资源:http:

100.webservice里能返回dataset而不能返回datatable的原因
原因是设计是留下来的,datatable、datarow、dataview、dataviewmanager这几个对象不是连续的,所以不能在webservices中被返回。
解决办法是:
用dataset返回而不用datatable返回,dataset可以含有多个datatable。

97.WebService 支持的数据类型
代码
ASP.NET WebService 支持绝大多数的基元类型及其数组,另外还支持自定义的结构(Struct)、类型(Class)、枚举(Enum)、DataSet、XmlElement、XmlNode、集合(IEnumerable
/
ICollection)等。
ASP.NET WebService 使用 XmlSerializer 进行序列化操作,对于自定义类型要注意以下几点:
1
. 只能序列化可读写公共属性和字段。只读属性(
get
;)、只读字段(
readonly
)、常量(
const
)以及所有的非
public
数据成员都不会被序列化。
2
. 自定义类型必须具有不接受任何参数的默认构造函数。
3
. 不能序列化方法。客户端生成的代理对象不包含任何自定义类型方法(不是WebMethod)。
基于以上几点,因此我们最好只定义纯粹用来传输复合数据的数据类型(Data Object)。
以下是一些演示代码。
基元类型

- 开始=>运行... =>gpedit.msc=>本地计算机策略=>计算机配置=>Windows设置=>安全设置=>本地策略=>安全选项。找到:“网络安全:LAN管理器身份验证级别”项,默认值“没有定义”改为“发送LM & NTLM响应”
