大家好：
      刚辞职，想找份 Asp.net 程序员的工作,工作地点在深圳.（工作已两年）
      哪位兄弟姐妹招人的话看下,可以直接联系.
      废话少说,还是简单附上相关信息:

1、基本信息

         姓名：李兵                           性别：男                                       工作时间：两年
     毕业学校：兰州大学                    英语：六级                          邮箱：music000libing@gmail.com

2、工作经历

A：2007.3—2008.7 深圳市邦德教育（www.bond520.com）

    1、邦德学员管理系统：需求分析、系统设计、编码、调试、完善、部署、维护（承担85%的工作 asp.net）
    2、邦德短信系统：需求分析、系统设计、编码、调试（独立完成 asp.net）   3、公司OA相关程序的完善（asp）

   学员管理系统：因公司所属行业的特点，公司目前在深圳市5个行政区都开设有分点（目前大约20个），综合系统数据量、网速、费用、安全性、其他业务（如语音电话）多方面的因素，网络架构采用的是：每个分点架设一个服务器与VPN，各服务器同时作为应用程序服务器与数据库服务器，同时采用一个大型VPN将公司各分点VPN连接起来形成一个局域网。同时，还存在一个总服务器，各分点服务器每天某一时刻定时向总服务器发送本分点当天最新数据，以对数据进行分析统计。这样，数据分发就成了系统设计的一个难点，因为只发送当天新增、更新的数据（减少数据传输量），所以系统设计时给数据库所有表新增了一个时间戳字段，同时采用作业来完成此任务（总服务器数据有一天延迟）。系统从需求分析到设计，都由本人单独完成，后因时间不足，带领一位同事完成系统其中一个模块，其余五个模块由本人完成。同时，系统采用了Asp.net Ajax、WebService，提升了用户体验。除框架页面布局由一位同事完成外，其余所有页面都由我完成。

邦德短信系统：采用亿美短信发送组件，同时结合公司现有的OA系统进行开发，实现公司内部的短信分级申请、发送、审核（如短信管理中心——片区——分点——行政部门），同时结合学员管理系统实现：教师给自己所带学员发送短信、公司给学员发送短信的目的。因为要考虑到现有的OA系统与学员管理系统，所以三个系统的衔接就成为系统设计的难点。系统的需求分析、设计、编码、调试、界面均由本人独立完成。

Sqlserver中Compute By子句用法分析

music000 — Tue, 29 Jan 2008 10:39:00 GMT

使用Compute by子句和行统计函数（count,sum,max,avg,min等），可以统计排序中结果完全相同的列，统计值作为查询结果以附加行的形式显示，

语法：Compute avg|count|max|min|sum by 表达式

1、举一个例子

比如有一个数据表：表名为person,三个字段分别为 name,age,country

select name,country,age from person where ?? order by a compute sum(age),max(age),min(age) by country

这个语句在查询时将数据按照country分组，然后分别显示每组的详细信息和统计信息。结果可能如下：

name country age

张三                  中国                        16
李四                  中国                        21
王五                  中国                        24

sum max min

61 24 16

=================================

name country age

泰森                     美国                         20
布什                     美国                         24
盖茨                     美国                         25

sum max min

69 25 20

=============================================

name country age

妓子                  日本                           12
完犊子                日本                           14
猪生逆子              日本                           15

sum max min

41 15 12

我们很容易看出她其实是在一个查询结果中包含了三个子查询（根据country不同而分的组），每个子查询又包含两个子查询（一个是详细信息，一个是统计信息）

2、compute by 子句的规则：

（1）不能将distinct与行统计函数一起使用

（2）compute ？？？ by 子句中？？？出的列必须出现在选择列表中

（3）不能在含有compute by 子句的语句中使用select into 子句，因为包括compute 子句的语句会产生不规则的行。

（4）如果使用了compute by子句，则必须使用order by 子句，而且compute by子句中的列必须包含在order by 子句中，并且对列的前后顺序和起始项都要一致（说白了compute by子句中的列必须是order by子句中列表的全部，或者前边的连续几个）。

（5）如果compute 省略了 by ，则order by 也可以省略

（6）如果compute by 子句包含多列时，会将一个组（第一个列分的组）分成若干个子组（利用后面的列），并对每层子组进行统计。

（7）使用多个compute by子句时，会分别按不同的组统计出结果。详细信息还是按照正常的第一个分组方式显示。

（8）compute by 子句中可以使用多个统计函数，他们互不影响

（9）compute by 子句中可以不包含by ,而只用compute 此时不对前面信息分组，而只对全部信息进行统计。

A Preview of HTML 5

music000 — Fri, 14 Dec 2007 16:20:00 GMT

Abstract

The web is constantly evolving. New and innovative websites are being created every day,
pushing the boundaries of HTML in every direction. HTML 4 has been around for nearly a decade now, and publishers seeking new techniques to provide enhanced functionality are being held back by the constraints of the language and browsers.

To give authors more flexibility and interoperability, and enable more interactive and exciting websites and applications, HTML 5 introduces and enhances a wide range of features including form controls, APIs, multimedia, structure, and semantics.

Work on HTML 5, which commenced in 2004, is currently being carried out in a joint effort between the W3C HTML WG and the WHATWG. Many key players are participating in the W3C effort including representatives from the four major browser vendors: Apple, Mozilla, Opera, and Microsoft; and a range of other organisations and individuals with many diverse interests and expertise.

Note that the specification is still a work in progress and quite a long way from completion. As such, it is possible that any feature discussed in this article may change in the future. This article is intended to provide a brief introduction to some of the major features as they are in the current draft.

Structure

HTML 5 introduces a whole set of new elements that make it much easier to structure pages. Most HTML 4 pages include a variety of common structures, such as headers, footers and columns and today, it is fairly common to mark them up using div elements, giving each a descriptive id or class.

Diagram illustrates a typical two-column layout marked up using divs with id and class attributes. It contains a header, footer, and horizontal navigation bar below the header. The main content contains an article and sidebar on the right.

The use of div elements is largely because current versions of HTML 4 lack the necessary semantics for describing these parts more specifically. HTML 5 addresses this issue by introducing new elements for representing each of these different sections.

The div elements can be replaced with the new elements: header, nav, section, article, aside, and footer.

The markup for that document could look like the following:


  ...

  ...

  
    
      ...
    

  

  ...

  ...

There are several advantages to using these elements. When used in conjunction with the heading elements (h1 to h6), all of these provide a way to mark up nested sections with heading levels, beyond the six levels possible with previous versions of HTML. The specification includes a detailed algorithm for generating an outline that takes the structure of these elements into account and remains backwards compatible with previous versions. This can be used by both authoring tools and browsers to generate tables of contents to assist users with navigating the document.

For example, the following markup structure marked up with nested section and h1 elements:


  Level 1

  
    Level 2

    
      Level 3

Note that for better compatibility with current browsers, it is also possible to make use of the other heading elements (h2 to h6) appropriately in place of the h1 elements.

By identifying the purpose of sections in the page using specific sectioning elements, assistive technology can help the user to more easily navigate the page. For example, they can easily skip over the navigation section or quickly jump from one article to the next without the need for authors to provide skip links. Authors also benefit because replacing many of the divs in the document with one of several distinct elements can help make the source code clearer and easier to author.

The header element represents the header of a section. Headers may contain more than just the section’s heading—for example it would be reasonable for the header to include sub headings, version history information or bylines.

The footer element represents the footer for the section it applies to. A footer typically contains information about its section such as who wrote it, links to related documents, copyright data, and the like.

The nav element represents a section of navigation links. It is suitable for either site navigation or a table of contents.

    About

The aside element is for content that is tangentially related to the content around it, and is typically useful for marking up sidebars.

The section element represents a generic section of a document or application, such as a chapter, for example.


  Chapter 1: The Period

  It was the best of times, it was the worst of times,
     it was the age of wisdom, it was the age of foolishness,
     it was the epoch of belief, it was the epoch of incredulity,
     it was the season of Light, it was the season of Darkness,
     ...

(Excerpt from A Tale of Two Cities)

The article element represents an independent section of a document, page or site. It is suitable for content like news or blog articles, forum posts or individual comments.

  That's another great article!

Video and Audio

In recent years, video and audio on the web has become increasingly viable and sites like YouTube, Viddler, Revver, MySpace, and dozens of others are making it easy for anyone to publish video and audio. However, since HTML currently lacks the necessary means to successfully embed and control multimedia itself, many sites are relying on Flash to provide that functionality. Although it is possible to embed multimedia using various plug-ins (such as QuickTime, Windows Media, etc.), Flash is currently the only widely deployed plugin that provides a cross-browser compatible solution with the desired APIs for developers.

As evidenced by the various Flash-based media players, authors are interested in providing their own custom-designed user interfaces, which generally allow users to play, pause, stop, seek, and adjust volume. The plan is to provide this functionality in browsers by adding native support for embedding video and audio and providing DOM APIs for scripts to control the playback.

The new video and audio elements make this really easy. Most of the APIs are shared between the two elements, with the only differences being related to the inherent differences between visual and non-visual media.

Both Opera and WebKit have released builds with partial support for the video element. You may download the experimental build of Opera or a recent nightly build of WebKit to try out these examples. Opera includes support for Ogg Theora and WebKit supports all the formats that are supported by QuickTime, including third party codecs.

The simplest way to embed a video is to use a video element and allow the browser to provide a default user interface. The controls attribute is a boolean attribute that indicates whether or not the author wants this UI on or off by default.

width="320" height="240">
    Download movie

The optional poster attribute can be used to specify an image which will be displayed in place of the video before the video has begun playing. Although there are some video formats that support their own poster frame feature, such as MPEG-4, this provides an alternative solution that can work independently of the video format.

It is just as simple to embed audio into a page using the audio element. Most of the attributes are common between the video and audio elements, although for obvious reasons, the audio element lacks the width, height, and poster attributes.


    Download song

HTML 5 provides the source element for specifying alternative video and audio files which the browser may choose from based on its media type or codec support. The media attribute can be used to specify a media query for selection based on the device limitations and the type attribute for specifying the media type and codecs. Note that when using the source elements, the src attribute needs to be omitted from their parent video or audio element or the alternatives given by the source elements will be ignored.


        media="handheld">
        codecs=theora, vorbis">

For authors who want a little more control over the user interface so that they can make it fit the overall design of the web page, the extensive API provides several methods and events to let scripts control the playback of the media. The simplest methods to use are the play(), pause(), and setting currentTime to rewind to the beginning. The following example illustrates the use of these.

There are many other attributes and APIs available for the video and audio elements that have not been discussed here. For more information, you should consult the current draft specification.

Document Representation

Unlike previous versions of HTML and XHTML, which are defined in terms of their syntax, HTML 5 is being defined in terms of the Document Object Model (DOM)—the tree representation used internally by browsers to represent the document. For example, consider a very simple document consisting of a title, heading and paragraph. The DOM tree could look something like this:

The DOM tree includes a title element in the head and h1 and p elements in the body.

The advantage of defining HTML 5 in terms of the DOM is that the language itself can be defined independently of the syntax. There are primarily two syntaxes that can be used to represent HTML documents: the HTML serialisation (known as HTML 5) and the XML serialisation (known as XHTML 5).

The HTML serialisation refers to the syntax that is inspired by the SGML syntax from earlier versions of HTML, but defined to be more compatible with the way browsers actually handle HTML in practice.

An HTML Document

Example

This is an example HTML document.

Note that like previous versions of HTML, some tags are optional and are automatically implied.

The XML serialisation refers to the syntax using XML 1.0 and namespaces, just like XHTML 1.0.

An HTML Document

Example

This is an example HTML document.

Excluding differences in whitespace and the presence of the xmlns attribute, those two examples are equivalent.

Browsers use the MIME type to distinguish between the two. Any document served as text/html must conform to the requirements for the HTML serialisation and any document served with an XML MIME type such as application/xhtml+xml must conform to the requirements for the XML serialisation.

Authors should make an informed choice about which serialisation to use, which may be dependent on a number of different factors. Authors should not be unconditionally forced to use one or the other; each one is optimised for different situations.

Benefits of Using HTML

Backwards compatible with existing browsers
Authors are already familiar with the syntax
The lenient and forgiving syntax means there will be no user-hostile “Yellow Screen of Death” if a mistake accidentally slips through
Convenient shorthand syntax, e.g. authors can omit some tags and attribute values

Benefits of Using XHTML

Strict XML syntax encourages authors to write well-formed markup, which some authors may find easier to maintain
Integrates directly with other XML vocabularies, such as SVG and MathML
Allows the use of XML Processing, which some authors use as part of their editing and/or publishing processes

How to Contribute

Work on HTML 5 is rapidly progressing, yet it is still expected to continue for several years. Due to the requirement to produce test cases and achieve interoperable implementations, current estimates have work finishing in around ten to fifteen years. During this process, feedback from a wide range of people including, among others, web designers and developers, CMS and authoring tool vendors, and browser vendors is vital to ensure its success. Everyone is not only welcome, but actively encouraged to contribute feedback on HTML 5.

In addition to the specification, there are several other related efforts designed to help people better understand the work.

The Differences from HTML 4 describes the changes that have occurred since the previous version of HTML.
The HTML Design Principles discuss principles used to help make decisions, and will help you understand the rationale behind many of the current design decisions.
The Web Developer’s Guide to HTML 5, which only recently began, is being written to help web designers and developers understand everything they need to know to write conforming HTML 5 documents, and provide guidelines and describe best practices.

There are numerous venues through which you may contribute. You may join the W3C’s HTML WG and subscribe/contribute to the HTML WG mailing lists or wiki. You may also subscribe and contribute to the any of the WHATWG mailing lists, post to the WHATWG forum, post comments or write articles on the WHATWG blog.

15 Rules for Faster-Loading Web Sites

music000 — Fri, 14 Dec 2007 13:23:00 GMT

These rules are the key to speeding up your web pages. They've been tested on some of the most popular sites on the Internet and have successfully reduced the response times of those pages by 25-50%.

The key insight behind these best practices is the realization that only 10-20% of the total end-user response time is spent getting the HTML document to the browser. You need to focus on the other 80-90% if you want to make your pages noticeably faster. These rules are the best practices for optimizing the way servers and browsers handle that 80-90% of the user experience.

这两天不爽——公车上被误认为色狼、游泳撞破上嘴唇

music000 — Sat, 25 Aug 2007 05:01:00 GMT

这两天很不爽：
    1、前天坐71路公交从莲花北到市民中心东，车上人挤人，运气不好，被挤到投币箱旁边，左手还好抓住了扶手，右手就没地方可扶了，只好抓住投币箱。正好一个MM的屁股对着投币箱，在车突然转弯的时候，MM的屁股就对着我的右手背撞过来，我当时也没反应过来，等我反应过来的时候，MM已经开始生气了。哎！被当成是色狼了——摸MM屁股的色狼！！！很想向她道歉的，但我是故意的吗？算了！不想了！
   2、下班后吃完饭没事，和同事一块去游泳，一口气潜下去，起来的时候就天昏地暗了，撞墙了，额头撞了个大包，上嘴唇撞破了，还不停流血。回去一看，噢，好大一个口子，就像是牙齿咬的一样。第二天上班，同事见面就问：这是怎么了？别太猛了！
      丢人啊！

然后在取数据的时候，用存储过程取出对应的数据，如 5-8，4-9，3-10，4-11，作为4条数据取出，这个时候就要获取‘|’的个数了（在项目中，‘|’的个数是不定的），然后一堆的 left、right、charindex、len、substring 就可以获取数据了。

还是写方法吧：
--用两个字符代替特殊符相减即可
declare @num_split int         --分隔符的个数
            select @num_split = len(replace(@sc_rs1_new,'|','||'))-len(@sc_rs1_new) --@sc_rs1_new 待检测的字符

关于GridView导出Excel的一些问题（采用Ajax出现的的问题及解决方法）

music000 — Fri, 24 Aug 2007 10:57:00 GMT

以前用GridView导出Excel没碰到什么问题，（注： enableEventValidation 属性必须设置为 "false"——直接在页面设置或在配置文件里设置），但采用Ajax后就出问题了，错误提示：Details Error parsing near '

原因：
导出Excel的按钮放置在里面，点击按钮后只输出了“

解决方法：
放到外面（注：不要放在任何的中）

以下为导出Excel方法：

///

/// 重载方法——VerifyRenderingInServerForm （必须添加）
///

    ///
    public override void VerifyRenderingInServerForm(Control control)
    {

    }

    ///

/// 生成报表
///

    ///
    ///
    protected void ImageButtonexcel_Click(object sender, EventArgs e)
    {
        Response.ClearContent();

        Response.AddHeader("content-disposition", "attachment; filename=MyExcelFile.xls");

        Response.ContentType = "application/excel";

        StringWriter sw = new StringWriter();

        HtmlTextWriter htw = new HtmlTextWriter(sw);

        GridView1.RenderControl(htw);

        Response.Write(sw.ToString());

        Response.End();
    }

固定表头

music000 — Fri, 24 Aug 2007 10:17:00 GMT

1、采用 expression（IE6中可运行,会抖动，感觉不爽）
<style>
        #FixedTitleRow{
            position: relative;
            top: expression(this.offsetParent.scrollTop);
            z-index: 10;
            background-color: #E6ECF0;
        }

        #FixedTitleColumn{
            position: relative;
            left: expression(this.parentElement.offsetParent.scrollLeft);
        }

        #FixedDataColumn{
            position: relative;
            left: expression(this.parentElement.offsetParent.parentElement.scrollLeft);
            background-color: #E6ECF0;
        }
    style>

2、判断浏览器类型（ie6中可以用，这个不会抖）


3、hack (固定某容器在页面位置：ie7-firefox可以直接写 position:fixed，ie6 就不可以了)
#FixTitle
{
    top:0px;
    width:235px;
    float:right;
    position:fixed;
}
*html #FixTitle {
    position:absolute;
    right:17px; /*only for ie*/
}
html {
    overflow:auto; !important;
    overflow:hideden;
}

安装 WebDesigner 之后，ASPNET 帐户没有对 IIS　的访问权。

music000 — Fri, 24 Nov 2006 13:15:00 GMT

昨天安装 WebDesigner 之后，打开测试网站，出错！！！
提示：ASPNET 帐户没有对 IIS　的访问权。
解决方法：再安装一遍 dotnetframework（运行dotnetfx.exe：安装文件的wcu\dotnetframework 目录下）——修复。感觉时间比较长。
还有一个办法：重新注册 IIS，运行　aspnet_regiis -i（C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727目录）。没试过，看资料而已。不过我想，这样不是还得再安装　dotnetframework　么，因为　dotnetframework　运行于　IIS　之上的。（注：IIS　重装之后，必须重新安装dotnetframework）
以上什么原因引起的？？？

另外还有一个问题：win2003 server 版本的操作系统，同时安装1.0版本的dotnetframwork 和2.0版本的dotnetframwork，如果有两个项目分别采用两个版本的dotnetframwork，且采用同一个进程，则两个项目只能有一个正常工作，而另外一个报错，出错信息（忘记了，明天补上），只要按照出错信息的提示，察看系统的“事件查看器”，再在 IIS 中开辟一个新的进程（注意：建立原进程副本没用，必须新建一个进程），两个项目分别采用不同的进程即可正常工作。

有点难度的 sql，行列转换

music000 — Wed, 22 Nov 2006 13:44:00 GMT

现在有这样一个数据表student
name object score
a     EN     89
a     CH     78
a     HO     99
b     EN     34
b     CH     88
b     HO     66
.
.
.
.

要求生成下面样式
name EN CH HO
a    89 78 99
b    34 88 66

方法：
CREATE TABLE t(name VARCHAR(10), object VARCHAR(10), score INT)
INSERT t SELECT 'a',      'EN' ,   89
UNION ALL SELECT 'a',     'CH' ,   78
UNION ALL SELECT 'a' ,    'HO' ,   99
UNION ALL SELECT 'b' ,   'EN' ,   34
UNION ALL SELECT 'b'   , 'CH' ,   88
UNION ALL SELECT 'b'    , 'HO' ,   66

--object出现的不同值的个数是有限的那么使用
SELECT name,
EN=MAX(CASE WHEN object='EN' THEN score ELSE 0 END),
CH=MAX(CASE WHEN object='CH' THEN score ELSE 0 END),
HO=MAX(CASE WHEN object='HO' THEN score ELSE 0 END)
FROM t
GROUP BY name

--若object出现的不同值是不定的
DECLARE @sql VARCHAR(8000)
SET @sql='SELECT name'
SELECT @sql=@sql+',['+object+']=MAX(CASE object WHEN '''+object+''' THEN score ELSE 0 END)' FROM t GROUP BY object
EXEC(@sql+' FROM t GROUP BY name')

DROP TABLE t

asp.net 写的国家,省,城市三级联动——所想

music000 — Thu, 16 Nov 2006 12:54:00 GMT

摘要: 今天在 csdn 看到一个朋友用 asp.net 写的国家,省,城市三级联动，有了些想法。这个联动所有数据都存储在数据库中，并且每取一次数据都打开关闭数据库一次，这对于数据库服务器会不会有额外的开销呢？我的意思是指增加数据库服务器的负担。我个人认为并没有必要这样，我们可以一直让数据库连接打开，等取完所有数据后再关闭。也许你认为这样更耗资源，不是有数据库连接池吗？还有，这些数据我们可以将它看成是静阅读全文

如何列出数据库中的所有用户表名？（视图、存储过程...）

music000 — Wed, 15 Nov 2006 12:30:00 GMT

话不多说，sql 语句：
use dbname select name from sysobjects where xtype='u' ( or type='u')
/*
C = CHECK 约束
D = 默认值或 DEFAULT 约束
F = FOREIGN KEY 约束
L = 日志
FN = 标量函数
IF = 内嵌表函数
P = 存储过程
PK = PRIMARY KEY 约束（类型是 K）
RF = 复制筛选存储过程
S = 系统表
TF = 表函数
TR = 触发器
U = 用户表
UQ = UNIQUE 约束（类型是 K）
V = 视图
X = 扩展存储过程
*/

补上几个
1、获取实例中所有的数据库名称：

select name
from master..sysdatabases
--where dbid>4
order by name asc

2、判断某个表是否包含某个字段（结果为1：包含、0：不包含）

select count(1)
from syscolumns
where [name]='colname' and [id]=object_id('tblname')
