centamap on smartphone

Hong Kong Blog is down for maintainence for a few days so I use back Blogger.com for the time being. Just want to release a couple of photos:

I'm working on a very primitive Smartphone application on .NET Compact Framework that query the centamap server. In the first screen we'll input the X, Y (co-ordinates) and Z (zoom level) and press "Show Map":

Then the smartphone will do a query on the server to retrieve a map:

2003-08-18T21:17:00.000-07:00

在桌面上加了 shortcut 到 SP 2003 emulator, 十分方便. 我用了:

"F:\Progra~1\MICROS~2.NET\COMPAC~1\CONNEC~1\Bin\Emulator.exe" /CEImage "F:\Progra~1\WINDOW~2\wce420\SMARTP~1\EMULAT~1\SP_200~2.BIN" /skin "F:\Progra~1\WINDOW~2\wce420\SMARTP~1\EMULAT~1\SMARTP~1.XML" /MemorySize 64 /Ethernet true

找了好一陣子才找到如何把另一台 Web Server 上的一個 Image file 變成自己的 aspx 內的一個 Image object, 大概是:

using System.Net;
using System.IO;

private WebClient client;

client = new WebClient();
Stream rsp = client.OpenRead(imgLogo.ImageUrl);
System.Drawing.Image img = System.Drawing.Image.FromStream(rsp);

用 OpenRead() 時最好用 try catch 包住來處理 404 error.

O2 decided to wait for the next version of smartphone

2003-07-09T00:51:00.000-07:00

回想當初 WAP 推出時我都不太看好, 因覺得它仍未可以改變大多數人的上網習慣. 而用 PDA 上網一直都只是 IT 人的玩意. 但現在 Smartphone 給我很大的信心, 加上八月 3G 來臨, 應會為整個 market 帶來一個大衝擊.

Smartphone 和 WinCE .NET 可能是一個能讓我大展拳腳的平台, 但 Smartphone 2002 仍未是時候, 主要因為它不支持 .NET Compact Framework. 雖然玩過上手後我都好想買一部, 但我始終認為它只是一個過渡產品, 應再等一等. 而作為一個 programmer, 現階段應把精神放在 CF 上, 以 WinCE .NET 為基楚為將來作好準備.

C# 有這樣的 using 嗎?

The correct way to make sure that the connection is being closed properly is
with the Try finally construct, or in c# the "using" construct.

So it would look something like:
using(SqlConnection connection = new SqlConnection(connectionstring)) {
//do your work here
}

or
SqlConnection connection;
try{
connection = new SqlConnection(connectionstring);
//do your work here
}
finally{
connection.Dispose(); //or connection.Close();
}

These two structs are equivalent and the finally guarantees the closing of
your connection.

Cookieless Session

最近真係好忙, 想停低寫寫都冇時間... 一來要忙 User Group 的網站 ( 今天正式出街了! ), 二來公司也有兩個大 project 要做. 三來呢, 要搬屋, 梗係忙 D 架啦.

早兩天遇到一個有趣的問題. 話說我的 SearchDept Order form system 用了 session variables 來暫時記住 user 的名、分行、電話等資料. 但到launch 的時候分行 A 的 order 郤錯誤地拿到分行 B 的資料並 update 了 database. 追查後發現原來分行用的 proxy server 會把 data cache 三日, 導致分行 A 拿了分行 B 在 proxy server 的 cache. 好吧, 那我就轉用 cookies, cookies 是儲在 client 的, 應不會被 cache 吧. 但由於分行所用的 terminal service 是把 cookies 放在 terminal server 上的, 所以還是會亂. 最後的解決方法就是用 cookieless session, 把 session id 放在 url 就 ok 了.

An article I wrote for Welkin

The role of Rapid Application Development (RAD) is becoming more and more important in the business environment of Hong Kong. Many SMEs would like to have their tailor-made applications built in a short period, and at the same time they need to share information with partners and customers in an effective way.

This is where XML Web Services come in to act as glue and let applications in different companies communicate with one another. .NET Framework provides the infrastructure for building Web Services. It also offers a managed environment and let the developers concentrate on business logics rather than troubleshooting problems like versioning and memory management failures. Being the best programming tool I have ever seen in any language and on any platform, Visual Studio .NET will soon become a must-have in the developers' skill set if you are working on the Microsoft platform.

It is time for us to get prepared for the Web Service era and look into the .NET world. Let's work together for a brighter future of Hong Kong.

My reply to a braindump thread in IT4All

haha.. Usually my students will ask me this in the first lesson ~ that's a very sensitive topic, you're brave to raise the question here, Nam. This has to be handled carefully in front of the students. I'd response like this:

When we take any Microsoft exams, we have to sign digitally a non-disclosure agreement which states that we won't tell others about the exam contents. I have signed that agreement too, so as a responsible citizen I will NOT give any of you any questions that's appeared in my exam.

However, Microsoft does provide legal ways for us to get practice exams, and that is buying from websites like transcender, testking or others. If you really need practice before going to the real exam, buy from these legal places. 我都幫親過, it's 99% the same as real exams. I DO NOT recommend you all to buy one copy and share among yourselves because there's copyright on those questions too ~ ( strangely, those copyrights are owned by transcender rather than Microsoft I think, coz there is a 1% difference)

So, since there is a legal way to get practice exams, I assume Microsoft assumes the candidates to practice before they go to the real exam. Now of course we can memorzie all the answers and go into the exam room. But if that's what you want from a certification, I'll tell you how to get a copy of practice exams and you don't need to take my lessons at all. But if you choose to stay, please rethink the value of the certifications.

To me, the most valuable thing is the PROCESS when you PREPARE for the exams rather than the result sheets. Even if you buy practice exams, or get braindumps from somewhere else, did you just memorize the answers? Or will you look into each question and then dig through books and documentations to find its explanations? If you choose the latter one then bingo! you already passed the exam. So the problem does not lie in braindumps itself, it lies in how you treat them. If you just memorize them then you won't get the value of the cert even if you bought the questions through a legal way.

Many people are saying that the whole certification industry is losing its value. But in fact the value lies in your own heart. I'm an MCAD. Will anybody dare to come out and say, hey andy, 你都冇料既, are you a real MCAD? I guess not. Well of course I'm not a .NET God, I'll make mistakes too and there are still many many things I don't know in the .NET world. But others will know that I did PAY EFFORT to get my cert and that's where the recognition lies ~

BTW, I'm not an MCT, just a normal part-time trainer ~ :P

終於起番 listing server, 剛搞完 ResearchPortal 的 config, 主要 config 如下:
1. web.config 裏 impersonate=off
2. connection string 用 trusted connection
3. IIS security 用 anonymous, 不用 integrated windows authentication.
4. 要 set 過所有 stored proc 的 permission

另外, 所有 full-text index 在搬 server 後仍存在於 database 內, 但全部要 rebuild 及 repopulate.

回到家了, 沖過涼, 晨鳥都在唱歌了.
一直以來我都在等一個機會讓我的事業攀到頂峰, 這可能是一個很成功的網站, 但現還未出現, 而我好像剛錯過了一個機會了(IT4All).
又或者那是一種我很著迷的技術, 我對它的認識可以出本書 ~ 還會影響它未來的發展路向. 不過, 那可能是幾年後的事吧...

2003-04-25T10:44:00.000-07:00

一點半了, 仍在公司. server down 了, 上完堂後回到公司和同事一起救機. 現在該快完成了 ....

MCAD (是我回應別人的留言)

如果立志要做 programmer 的話, MCAD 絶對是現時最熱門的選擇. 我現時教緊兩班 full track, 加上 internal training 一星期要教七個 sessions, 據知我教的 CTEC 亦同時開了多班 MCAD. MCAD 是要成為 MCSD .NET 的必經之路, 全球現還未到四千人(首五千人可成為 Charter Member).

不過又是那句, 有 cert 雖好, 但最緊要還是自己肯捱肯做 ~

防火牆的情況在下午變得嚴重, 受感染的不只是我一台機, 整個係統要進行一次大手術. 在此只能奉勸各位一句: 記得落 service pack!

什麼!? 是我的 notebook 仔隊冧了公司的防火牆嗎? 噢... 還是等同事明天回來再算了...

今天想完成兩個 programme, 一個是 retrieve floorplan 的小程序, 另一個是 check duplicate search 的 stored proc. 希望上下午各完成一個 ~

2003-04-22T11:07:00.000-07:00

公司的防火牆冧了, 同事們正在搶修當中. 防火牆我不太懂, 我還是喜歡寫 programme 多些.

IT4All.com.hk

Michael 和 Peter 終於親自出手了, 速度果然快得驚人! 雖然只是拿別人的 code 來改, 但當中肯定是花了不少氣力的.

IT4All 出現後大家都在議論 HKNetUG 應何去何從, 我也認為 HKNetUG 的留言版會少了人氣, 但那也不一定是壞事呀, 只要大家都會聚在一個地方熱烈地討論就是了!

由新倉頡98a轉回用普通倉頡, 有相關字詞功能, 可打得快些.

為何開始

好, 回來了. 發現原來只要在 IE 的檢視-->編碼裏選 unicode 就可打 unicode. (right-click 是不行的).

開始 blogging 的原其實有二: 一是寫給未來的自己看. 我的記性不好, 常有 "我看過這技術但忘記了在哪裏看過" 的煩腦. 二是寫給其他編程人員看的, 讓他們也知道我的心路歷程.

在 google search 過"技術日記", 但只找到一些日本網頁, 是真的沒有人寫? 還是這東西有其他叫法呢? 我相信台灣那邊應該也有 technical bloggers, 但怎麼找不到?

給香港年輕人打氣 節錄自程序員2003-04, 拿到 HKNetUG 討論一下.

世界級的金融中心是不可能沒有強大的 IT 作為支撐, 而軟件人才的大量北上, 島內薪水偏低的 IT 職位大都為剛畢業的大學生所佔據, 導致報考港內大學軟件專業學生的數量急劇減少. 這甚至引起了香港知識和教育界的恐慌, 除了積極配合港府推出的 IT 專才輸入計劃、積極呼籲多給留港 IT 人員機會之外, 他們紛紛出面為在校學生打氣, 完全把香港 IT 的希望寄托於下一代開發人員.

目前香港有名的大學, 諸如中文大學、理工大學、城市大學和香港大學都加大了對學生的培養. 他們認為社會將繼續計算機化以提升生產力, 從而會在 IT 上做出投資, 所以仍然需要 IT 人才. 學校號召業界和在校學生不要灰心, IT 技術是世界通用的. 若有機會大家可值此時北上取經, 賺取多些內地經驗為自己增值. 教育界分析認為, 當前市場萎縮主要是因為信心危機, 業界對前景失去信心所致, 而 IT 人才始終是現代社會的必需品. 當社會經過一輪恐慌性的退縮後, 必將發覺 IT 的需求還在.

我從這裏開始

好了, 經過一輪掙扎後, 我終於決定用 unicode 來 blog. 因為我想同時出國和国, 繁簡兩用, 又不會令 blogger.com 產生亂碼 (例如打日月明後再 edit 會出現 HTML tag.)

為了寫好我的技術日記, 我還決定改打倉頡, 因為用廣東或速成的選字實在太慢了, 有礙我 blogging 的速度. 我的倉頡現在還是有限公司, 所以我買了一本倉頡小字典, 練了一個下晝就打了這麼多, 不錯吧!? 現在先去吃飯, 回來再打 ~

Ok, this is my first blog. �ڲ{�b�}�l�g�޳N��O�F.
After a little configuration I'm able to ftp my blogs to ftp.hmcheung.com, hahaha... it's really great.
hm.. what should I write here? I think some technical notes, some new things that I've learnt / seen on the day, etc...
Blogging should be important to every programmer. See how long I can keep this habit!
