Developing with VS2005 C#
設計概念：
語言(C#)
基本上以前寫了不少C的程式，所以先進入 C++，再找到 C++ vs C# 異同處。
Framework (.NET 2.0)
這部分躲不了，應該就只能透過一系列的範例程式來掌握怎麼快速利用 .NET 2.0 framework 的物件了。
以上是轉換的概念～

Write once, run on Mac & Windows? (C#)
I try to get into Mac OS X programing world recently. The link as below is the new oppertunity of C#.
Have a look!
English Version: Creating Mac OS X applications with MS Visual Studio Express http://mac.sillydog.org/dev/visual_studio.php
Chinese Version: http://www.iim.nctu.edu.tw/~toki/CSharpOnOSX/c%23osx.html
Maybe in the near futhure, we will see the the possibilty of "Write once, run on Mac & WIndows".
Of course, you can say Java already done this, but C# ? This is my point.

NMAKE : fatal error U1065: invalid option '-'
I found this message while building CE image.
Why? because of the MAKEFLAG cause nmake error.
So, clear the MAKEFLAG to resolve this problem.

PXA255 MSCx[2:0] setting?
I saw the MSC0_VAL in PXA255 initial code & tried to found how to calculate the best setting for PXA255 with Intel P30 Flash, Yamaha YGV628.
The RDFx, RDNx, RRRx registers are difficult to understand why the value of them came from.
For P30 Flash:
I found the Application Note 768 (Intel Strata Flash Memory(J3) to Intel PXA270 Applications Processor Design Guide). This document mentions the RDFx, RDNx, RRRx came from Intel PXA270 clock speed & flash read/write timing. So, that's it.

The Intel P30 Flash with Windows CE 4.2 FMD driver
1. I found the jflashmm could write correctly with P30 Flash. So, to fully understand the code of jflashmm could help me to know how to modify the CE driver.
1-1. modify the dbpxa255.dat (the memory map part)
1-2. use the Flash_891c_2_32.dat (the P30 series flash have 4 x 32K Block + 255 x 128K block)
the CE side:
2-1. to know the inside of FMD driver(Intel Strata) comes with CE 4.2.
2-2. to modify the strata driver to fit the P30 spec, especially the mechanism of block lock & block arrangement.

Installing CVSNT & WinCVS
1. Installing the CVSNT under my Windows XP pro.
- get the cvsnt-2.5.03.2260.msi from my software repository. (You could download the latest version from www.cvsnt.org)
- running the setup program of cvsnt (nothing specical)
- there is no need to reboot system after completed the install process.
- setup the defaul repositoy (example: Location: D:/CVSRepository, Name: /CVSRepository, Description: CVSRoot, Publish repository checked, Default repository checked, Online checked.)
- done.
2. Installing the WinCVS
- get the WinCvs2_0_2-4.zip from www.wincvs.org.
- running the setup program of WinCVS (choosing Typical)
- Set the CVS server related setting by clicking Admin/Login. (example: :pserver:allen@jupiter:/CVSRepository, format is :protocal:user@server:/repository)
- done.
PS: always keep in mind if there is code changed, use "update" before directly commit.

Found two interesting books...
While web surfing, I found two interesting books, Car PC Hacks & Mapping Hacks. These two books are related with my current job, the Smart Phone & PNA developing. So, I bought these two books. Maybe could give me more idea about my design.
