将python文件保存在python  安装文件夹的tmp文件夹中,
如: e:"Python25"tmp中,右击该文件,选择Edit with Idle选项,
在 Python Shell-> File-> Open 打开文件,弹出一个新的窗口,
选择 Run-> Run Module,会运行并得出结果.

Windows 的文件类型关联
如无法打开RUBY文件时:

> assoc .rb
File association not found for extension .rb

如果没有关联,则给它一个相关的文件类型:
> assoc .rb=rbFile

接着测试文件类型是否存在:
> ftype rbFile
File type 'rbFile' not found or no open command associated with it.

如果不存在,则手动建立:
> ftype rbFile="E:"Program Files"Windows NT"Accessories"wordpad.exe" "%1" %*
wordpad.exe(写字板)的路径自己定的.

最后,把 .rb加入环境变量PATHEXT中。如：
PATHEXT=.COM; .EXE; .BAT; .WSH; .rb

需要一些方法,网上赌博之类违法的事,俺不干.
唉,慢慢想吧!

     摘要: rss reader开发资料1）<<ajax in action>>书中 ch13/refactor/下的内容， 如要增加自己的rss feed,可在RSSReader_refactored.htm 中的 rssFeeds数组添加，如添加本blog的feed: http://www.cnblogs.com/mill2002/rss 则为: function createRS... 阅读全文

在命令提示符中使用antlr
进入到有ANTLR源文件所在文件夹中，如模拟计数器的源文件calc.g在j:/temp/calc中
1）在 j:> 时，键入 cd temp/calc 回车
2）j:\temp\calc> 下，键入 java antlr.Tool calc.g 回车
   会生成多个文件
3）编译示例中自带的Calc.java文件，如键入：
   javac Calc.java 回车
   会生成 Calc.class 文件
4）运行Calc.class 文件，如键入：
   java Calc 回车
   则光标在第一格闪烁，如键入：4+2；（不能少此分号；）
   输出结果为：<+ 4 2>
              value is :6.0

if can't use ruby in command line,choose a way from "Instant Rails": I-->Rails Application-->Open Ruby Console Window.

1.从WWW.CNBLOGS.COM上COPY一个RSS文件,保存为.XML后缀的文件,如ask.xml,将其
   保存到书中代码文件夹CH13/REFACTOR/FEEDS中.

2.打开RSSReader_refactored_local.htm文件,在
    <script>
   function createRSSReader() {
      var options = { rssFeeds: [
      "feeds/dave.xml", "feeds/eric.html"
      ] };

      var rssReader = new RSSReader('rssReader', options );
   }

</script>

的options数组中加入上述的文件,即"feeds/ask.xml"

3. 好象RSSReader_refactored_local.htm文件中的select的option

刚才试的方法:右上角的site ->Stylesheet Editor,在其中的
/* GENERAL */
/* style for module titles */
.Head   {
 }
进行设定.这样所有的模板容器都改了.

偶以前没有办法时,做法是自己上传一个模板容器，如k-dnnBlue（它是模仿DNN中的DNN-Blue的），然后将其中的
k-dnnBlue.ascx,container.css,container.xml这三个文件进行一些修改.
如在k-dnnBlue.ascx中;对<dnn:TITLE runat="server" id="dnnTITLE" />就增加了
CssClass="ContainerCrystalTitle".
变成了 <dnn:TITLE runat="server" id="dnnTITLE" CssClass="ContainerCrystalTitle"/>

而在container.css中加入了 ContainerCrystalTitle的定义,如
.ContainerCrystalTitle
{
    font-family: Tahoma, Arial, Helvetica;
    font-size:  11px;
    font-weight: Bold;
    color:#FFFFFF
}

并在container.xml中加入
  <Object>
  <Token>[TITLE]</Token>
  <Settings>
   <Setting>
    <Name>CssClass</Name>
    <Value>ContainerCrystalTitle</Value>
   </Setting>
  </Settings>
  </Object>
这样就硬是更改了Title的样式.偶也是没有办法.

 

 

 how to compile source code of "Data Structures & Algorithm Analysis in Java" writen by Weiss
    Another question:How to demo the examples under  folder of DataStructures?

    a) put a build.xml file in the folder the source code in
    b) type 'ant' in command line
    c) i just made a one copy of build.xml from another place and put it in same folder of source code.
             only one thing about 'property name="srcdir" value="src"'  is to be concerned.
    d) when compiling source code of the folder named Miscellaneous, first i copied all of the source code into
             folder named src,then type ant in command line and appeared 36 errors which of them displays
             [javac] K:\game\tutorial\CodeWin\src\Concordance2.java:3: package DataStructures does not exist
             [javac] import DataStructures.*;
      This indicates the source code of Miscellaneous needs package named DataStructures.
      Then i copy folder of DataStructures into folder of src and type ant again,this time show
           'Success'

     要在命令行中run the examples under folder of DataStructures,note a sentence of 'package DataStructure;' in the source code file, so must tell  java.exe find some class (such as LinkedList) under folder of DataStructure. in Command Line,should type "java DataStructures/LinkedList",if entry the DataStructures by command of 'cd DataStructures' and then type 'java LinkedList' you will see the followings:
     K:\game\tutorial>cd codewin/DataStructures
     K:\game\tutorial\CodeWin\DataStructures>java LinkedList
     Exception in thread "main" java.lang.NoClassDefFoundError: LinkedList (wrong nam

1.Developing Games in Java, written by David Brackeen,url: www.brackeen.com
   book all src:X:\game
   Usage:
   in command line,type java SpriteTest1,for example and a sprite can be seen on screen.
   in terminal look like this,x:\game\ch02src>java SpriteTest1 <Enter>
 
   If u want to compile java file with Ant,enter the ch02src and just type ant in command line.

   Before using j2sdk1.4.2 and ant-1.4.1,system parameters should be setted first.
   like these:
   ANT_HOME      x:\ant
   JAVA_HOME    x:\j2sdk1.4.2

 

Interacting with the Demo's(http://rossum.sourceforge.net/)

	The illustration at the left shows the Floor Plan for the Trinity College Fire-Fighting Home Robot Contest. The Server (simulator) reads the floor plan at start up. By default, the Server runs with a Graphical User Interface (GUI). If you are running time trials or wish to treat the Server as a background process, you can suppress the GUI by adjusting options in the RP1 properties file (see the Users's Guide for more details.) The simulated robot in the lower-left section of the display was uploaded by the client application when it connected to the Server. Although the Server provides a virtual world, the inhabitants of that world are provided by the client applications. The red circle with the letter "F" indicates the target, a candle representing the fire which the robot contestant is to extinguish. The green "homeplate" represents the home placement, the robot's starting position.
