    Introduction

    Hi there avid programmers! It注释:s great to see you at the start of a new series of articles on objects and Visual Basic.

    Well, lets start with the basics (excuse the pun): I注释:m Sam Huggill and I will be guiding you through the jungle of class modules, ActiveX components, DLLs and much more over the coming weeks. If you ever had any doubts about objects, read on!

    In this first part, I will be covering the following things:

    - What注释:s an object?

    - Where can I pick up an object?

    - Why should I use objects?

    - My first object!

    OK - Now that we are clear about what I注释:m supposed to be doing, we better proceed! But just before we do, I want to remind you that I want to hear what you think about this tutorial. Boring, interesting, too much or too little? Let me know by clicking on the Post Feedback Now link at the bottom of each page of this tutorial.

    Right, on with the learning!

    What注释:s an object?

    Is it a bird? Is it a plane? No, it注释:s an object! (Sorry for those of you who never watched superman :)

    Objects are things that you can program with, things that make programming easier. They contain a set of methods and properties that allow you to make the object do certain things without actually having to look at the objects code. For example, you have probably used the following statement many times:

    Text1.Text = ""

    Remeber that? Well, what you are doing is setting the property Text, of the text box object Text1 to equal nothing.

    See, objects are really easy, you注释:ve been using them ever since that first "Hello World!" program you wrote!

    In fact, all the controls you see on your VB toolbox are all objects. For a better look at objects, either press F2 or click View, Object Browser. This nifty little window allows you to see all the properties and methods of the objects currently loaded.

    If you click on the combo box that currently contains , and select VB, you will see a list (on the left) of all the standard controls in your toolbox.

    Just try clicking on TextBox. See, recognise some of those methods and properties? (I sure hope so :)

    Here注释:s what we注释:ve done so far:

    - Example of the Textbox object

    - Realised how simple objects can be (yes, you have really :)

    - Taken a look inside the object browser

    Right, lets find out where you get other objects from >>

  • geektool--一款很geek的工具

    今天尝试一款很geek的工具

    geektool

    听名字就超级geek有木有

    get it

    geektool website

    从官网直接下载app,一键傻瓜式安装。

    use it

    GeekTool started it's life as a software mostly used by computer scientists and geeks, hence the name.

    documentation的第一句话,名字的由来:计算机科学家和geeks!

    but,别害怕,后面还有:

    The time passing by, I finally realized that those geeks from the beginning of GeekTool made things so cool that the that mere mortals wanted to use it as well!

    GeekTool is now much easier to use by anyone, let's see what we can do with it.

    无名小卒也可以轻松使用了。嗯,就是这个意思。

    what it can do

    首先还是了解下能干什么,就是能够定制化你的桌面,有四种工作模式:

    File

    Shell

    Image

    Web

    每种模式最终目的是在你的桌面呈现一些信息,但都遵循下面的几个原则:每个桌面都展示,可以放到最上层(默认不是,也最好不要),可以分组管理(就是可以选择group去展示)

    Logs Geeklet -- 打印日志

    添加一个log窗口 => 在属性窗口中的file选项中找到系统日志 (/var/log/system.log)

    特点:

    自动滚动

    支持正则

    当然可以是任何变动的(日志)文件,实在是装x利器。

    比如新建一个todolist的文档,然后编辑这个文档,就能够在桌面显示你的todo列表。

    Shell Geeklet -- shell窗口

    最强大的功能,这个需要会命令行。。。

    Image Geeklet -- 相册

    可以选择文件夹或者单张图片,设定刷新频率。。。

    Web Geeklet -- 网站

    打开一个网页,设定刷新时间。

    others

    how to reset your geektool :

    open a terminal window and =>

    defaults delete org.tynsoe.geektool3

    defaults delete org.tynsoe.geeklet.file

    defaults delete org.tynsoe.geeklet.shell

    defaults delete org.tynsoe.geeklet.image

    defaults delete org.tynsoe.geeklet.web

    as you can see, /Library/Preferences/org.tynsoe.geeklet~~ 就是保存设置的地方。

    more

    examples

    里面好多好玩的东西,just have fun!
