AJAX Framework: YUI, DOJO or GWT

Google Web Toolkit - Build AJAX apps in the Java language
White code in java, and then use GWT to compile to html and javascript file.

The Yahoo! User Interface (YUI) Library is a set of utilities and controls, written in JavaScript, for building richly interactive web applications using techniques such as DOM scripting, DHTML and AJAX. The YUI Library also includes several core CSS resources.

Dojo - is an Open Source DHTML toolkit written in JavaScript. It builds on several contributed code bases (nWidgets, Burstlib, f(m)), which is why we refer to it sometimes as a "unified" toolkit. Dojo aims to solve some long-standing historical problems with DHTML which prevented mass adoption of dynamic web application development.
One book for Dojo.

MochiKit - A lightweight Javascript library.

MooTools is a compact, modular, Object-Oriented JavaScript framework designed for the intermediate to advanced JavaScript developer. It allows you to write powerful, flexible, and cross-browser code with its elegant, well documented, and coherent API.

Prototype is a JavaScript Framework that aims to ease development of dynamic web applications.

Format DateTime in XSLT in .Net 2.0

In .Net 2.0, we can use XslCompiledTransform to perform a transformation on XML:
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(xmlstring);

XslCompiledTransform xslDoc = new XslCompiledTransform(true);
StringReader strReader = new StringReader(xslstring);
XmlTextReader txtReader = new XmlTextReader(strReader);
xslDoc.Load(txtReader);

StringWriter strWriter = new StringWriter();
xslDoc.Transform(xmlDoc, null, strWriter);
outputstring = strWriter.ToString();

It's easy and simple to call this functions. But it takes time to write a working style sheet. One difficult thing is do datetime formating.

format-number is include in XSLT 1.0 , but not format-date. Each company have their extension to do that. For microsoft, this is the way doing it:

〈?xml version="1.0" encoding="UTF-8"?>
〈xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:ms="urn:schemas-microsoft-com:xslt" xmlns:dt="urn:schemas-microsoft-com:datatypes">
〈xsl:template match="/DocumentElement">
〈table border="1">
〈tr bgcolor="grey">
〈th>BaseCurrExch〈/th>
〈th>OrdDate〈/th>
〈/tr>
〈xsl:for-each select="Row">
〈tr bgcolor="white">
〈td>〈xsl:value-of select="format-number(BaseCurrExch,'#.00')"/>〈/td>
〈td>〈xsl:value-of select="ms:format-date(OrdDate, 'MM/dd/yyyy')"/>〈/td>
〈/tr>
〈/xsl:for-each>
〈/table>
〈/xsl:template>
〈/xsl:stylesheet>

MyGeneration and O/R Mapping Practics

First time, you have to go to the setting page to set up connection string and Database target mapping. For SQL Server, I use "DBType" as DbTarget.

Some template in MyGeneration can generate data access code according the key and index define on data fields. This will save your time to create your own code manually. We use to have these fields:
PKID (int,4) Indentity
DateCreated(datetime, 8)
LastUpdate(datetime, 8)
rowguid(uniqueidentifier, 16): (newid())

Use SmtpClient to Send Email

In Asp.Net 2.0, we can use SmtpClient to send email.
MailAddress from = new MailAddress(emailfrom);
MailAddress to = new MailAddress(emailto);
MailMessage mm = new MailMessage(from, to);
mm.Subject = subject;
mm.Body = body;
mm.IsBodyHtml = true;
mm.Attachments.Add(New Attachment(AttachmentFile.PostedFile.InputStream， AttachmentFile.FileName))

SmtpClient sc = new SmtpClient();
sc.DeliveryMethod = SmtpDeliveryMethod.Network; // Network;PickupDirectoryFromIis; SpecifiedPickupDirectory
sc.Host = host;
sc.Port = Convert.ToInt32(port)
sc.Credentials = New NetworkCredential(username， password);
sc.Send(mm);

Here AttachmentFile is a FileUpload control inside the page:
＜asp:FileUpload ID="AttachmentFile" runat="server" /＞

If we do not want to specify the Host information, we can config it inweb.config, and SmtpClient will use this setting to connect to SMTP server:
＜configuration＞
　＜system.net＞
　　＜mailSettings＞
　　　＜smtp＞
　　　　＜network host="relayServerHostname" port="portNumber" userName="username" password="password" /＞
　　　＜/smtp＞
　　＜/mailSettings＞
　＜/system.net＞
　＜system.web＞ ... ＜/system.web＞
＜/configuration＞

SmtpClient throws SmtpException exception.

Use WebSupergoo ABCPdf.Net component

This component can easy render HTML code to PDF output:
For example, we want all content inside the Literal control "litReport" to output to PDF, first we render the Literal web control to a string writer, then use AddImageHtml method of ABCPdf to load the content.

using System.Text;
using System.IO;
using WebSupergoo.ABCpdf5;
......

StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
litReport.RenderControl(htw);

Doc theDoc = new Doc();
theDoc.Color.Color = System.Drawing.Color.White;
theDoc.Rect.Inset(20,20);
int theID = 0;
theDoc.FrameRect();
theID = theDoc.AddImageHtml(sw.ToString());
while (true)
{
theDoc.FrameRect(); // add a black border
if (!theDoc.Chainable(theID))
break;
theDoc.Page = theDoc.AddPage();
theID = theDoc.AddImageToChain(theID);
}

After this, we use GetData to get the raw data and use BinaryWrite to output to browser.

Response.ContentType = "application/pdf;";
Response.AppendHeader("content-disposition", "attachment; filename=\"file.pdf\"");
Response.BinaryWrite(theDoc.GetData());
Response.Flush();
Response.End();

How to setup SVN on windows

1. Download
Subversion Find server side component, svn-1.4.2-setup.exe is for windows setup.
Svn service Run svn server (svnserve.exe) as MS Windows service (Don't need since SVN v1.4)
TortoiseSVN Client side component

2. Install and setup SVN server
Run setup file. Then Create a repository and configure access:
Create a new directory like d:\subversion\repositories, open a command line window and go inside this folder, run

svnadmin create "d:\subversion\repositories"

This will create repository stucture folder under d:\subversion\repositories, go to d:\subversion\repositories\conf, change file svnserve.conf, uncomment the following line:

[general]
password-db = passwd

change file passwd, uncomment the following line:

[users]

and add the username and password you want to use when connecting to your subversion server

3.Install svnservice, and run install.bat to install a service for SVN, then start service "Subversion Service"

Note:
From v1.4, svnserve can be run as a native Windows service. Use windows command line tools sc.exe to install svn service.

sc create svnservice
binpath= "c:\Subversion\bin\svnserve.exe --service -r D:\svnroot"
displayname= "SVNService"
depend= Tcpip
start= auto

where "svnservice" is any service name, and "D:\svnroot" is the repository, you can use --listen-port parameter as well.

Then you can use the following to start/stop svn service
net start svnservice
net stop svnservice

To delete svn service
sc delete svnservice

If the path to svnserve.exe contains spaces or other characters that
must be escaped, then you must enclose the path to svnserve.exe with
double-quotes, which themselves must be quoted using a backslash:

sc create svnservice
binpath= "\"c:\program files\subversion\bin\svnserve.exe\" ..."


4. In client side, install TortoiseSVN and reboot computer, then create one projects folder like d:\projects and right click this folder and click "Import" menu, use URL:

svn://ip/projects
The default port SVN used is 3690.

3-Tier Software Structure

http://blog.joycode.com/jgtm2000/archive/2003/12/29/10064.aspx

BTW：关于三层软件结构中的语义

我设计软件的时候有一个原则：不同的架构层次有不同的语义集，简单说，就是在不同的层次说不同的话。比如说业务需求里面的这样一句话：

“用户可以搜索与给定名称相同的图书”——这是客户的需求，在这一层次上，说的是“人话”。

反映到界面层，这个动作对应的方法就成了：

“GoSearchByName”

到了业务层，我喜欢用：

“GetBooksByName”

而进一步到了数据服务层，一律是数据操作用语：

“BookDataService::SelectByName”

同理可见：

注册新用户 - CreateUser - InsertUser
登录 - SignIn - UpdateStatus
注销 - LogOff - UpdateStatus

等等。。。这样可以有效避免名称上的混乱一致于不清楚代码所处的软件层次。当然你不必要用同样的方法，但是我们的团队很快的适应这样的命名规则，且工作的很好。也供大家参考吧。
