The Will Will Web | ASP.NET MVC 單元測試系列 (7)：Visual Studio Unit Test

透過 Visual Studio 裡的整合開發環境 (IDE) 結合單元測試開發是再便利不過的了，在 Visual Studio 開發工具中已經內建一套 Visual Studio Unit Testing 框架 (Framework)，可以方便協助你開發各式單元測試或整合測試的程式，工欲善其事、必先利其器，要善用他就必須先瞭解他，否則還是會事倍功半的，本篇文章會著重在 Visual Studio Unit Test 框架的概要介紹與快速上手的注意事項。

Subversion on CentOS

HowTos/Subversion – CentOS Wiki

Subversion isn’t just for coders and programmers…I know because I’m not one. I’ve begun to use it lately for many things, such as, backing up Nagios configurations, documents, and pretty much anything text based. I don’t know why I didn’t start using it sooner, but none the less, here I am. This document quickly explains how to install, configure, and use subversion locally, as well as across Apache on a network. For complete and complex configurations and installations seek the documentation provided. There is plenty of well written documentation on the subject, that far exceeds my knowlegde of the tool. This just helps get you started quickly, for those like me that just like to jump in head first into new things.

Snippet Saturday: limit() function
Posted on March 5, 2011 by Mims H Wright

So I’m sitting on a bunch of pretty useful code and I’m not sure how to share it with people. I could create a massive library that combines all the miscellaneous bits into a single, poorly documented library, but after looking at the Flash Game Dojo’s wiki, I’m starting to believe more strongly in the idea of releasing code in smaller pieces that achieve a particular function. So, I’m going to try to kick off this idea of #SnippetSaturday. I’m sure I won’t manage to post something every week but I’ll do my best. If you’ve got a blog or just twitter, I’d encourage you to join in too!

Anyway, here’s my first contribution. It’s a simple little function that limits a number between an upper and lower limit.

[VBNET] 抓取網頁部分內容

[VBNET] 抓取網頁部分內容 « 鄭子璉

很多網頁砍站軟體支援續傳、多線下載，多線下載觀念比較簡單，就是同一個檔利用多緒分別抓某個部分，再用二進位檔存取方式將抓得的結果直接寫入指定的範圍即可。

要知道怎樣做，可以先看規格書：
HTTP 1.0: RFC2068 14.36 節 Range
HTTP 1.1: RFC2616 14.35 節 Range

也就是說在 通訊協定中，檔頭加入：
Range: bytes=開始-結束
省略開始時，從 0 開始，省略結束時，自動抓到結尾。

我是認為寫程式前，應該先了解低階運作方式，通訊協定自然就是利用命令提示字元測試，例如輸入：
telnet tlcheng.twbbs.org 80
GET / HTTP/1.0
Range: bytes=100-199
傳回：
HTTP/1.1 206 Partial Content
Content-Length: 100
Content-Type: text/html
Content-Location: http://192.168.2.10/index.htm
Content-Range: bytes 100-199/3162
