备忘两个在Windows mobile开发中常用的how to. ^_^！

Reusability

imcm — Sat, 06 Mar 2010 11:34:00 +0800

A principal goal of object-oriented programming is to make the code you write as reusable as possible—to have it serve many different situations and applications—so that you can avoid reimplementing, even if only slightly differently, something that’s already been done.

Reusability is influenced by a variety of different factors, including:

      How reliable and bug-free the code is
      How clear the documentation is
      How simple and straightf

最近有点迷茫，感觉许多事情没有以前有激情了，这确实是个很可怕的事情，转帖此文章，与大家共勉。

关于网络字节序

imcm — Tue, 08 Sep 2009 15:50:00 +0800

这几天又开始做网络方面的应用了，既然是网络编程，字节序肯定是需要牢记的一个知识点了。贴篇文章，以备忘！

不同的CPU有不同的字节序类型这些字节序是指整数在内存中保存的顺序这个叫做主机序
最常见的有两种
1． Little endian：将低序字节存储在起始地址
2． Big endian：将高序字节存储在起始地址

LE little-endian
最符合人的思维的字节序
地址低位存储值的低位
地址高位存储值的高位
怎么讲是最符合人的思维的字节序，是因为从人的第一观感来说
低位值小，就应该放在内存地址小的地方，也即内存地址低位
反之，高位值就应该放在内存地址大的地方，也即内存地址高位

BE big-endian
最直观的字节序
地址低位存储值的高位
地址高位存储值的低位
为什么说直观，不要考虑对应关系
只需要把内存地址从左到右按照由低到高的顺序写出
把值

关于Symbian里面的mifconv

imcm — Mon, 10 Aug 2009 16:04:00 +0800

简单的说，mifconv是symbian提供的一个图像压缩打包工具，用于将svg/bmp格式的多个源文件合成一个mif/mbm复合文件。关于mifconv的更多介绍可参考相关文档，这里我这要介绍下它的用法。

通过命令行可看到mifconv的参数信息如下:

Utilising media keys on S60 devices

imcm — Tue, 14 Jul 2009 14:42:00 +0800

Description
Key presses of media keys cannot be detected in the same way as other key events. Media keys, such as Play/Pause, Stop, Volume Up/Down, Rewind, and Forward keys featured on some S60 3rd Edition devices do not generate normal key events that could be handled within the application framework, for example, in HandleKeyEventL() or OfferKeyEventL() .
Solution
Events from media keys can be handled with the Remote Control API . Below is a code snippet that demonstra

How To Use GSM Compression in Low-level Wave Recording.

1. How To Use GSM Compression in Low-level Wave RecordingSUMMARYRealtime GSM recording using the low-level waveXXX API can be accomplished by filling in an appropriated struct and then calling waveInOpen() with the WAVE_MAPPER option so that the GSM format specified in the struct will be used.MORE INFORMATIONAlong with the usual set of low-level waveXXX calls used in recording, and illustrated in such samples
