When working with mathematical simulations or engineering problems, it is not unusual to handle curves that contains thousands of points. Usually, displaying all the points is not useful, a number of them will be rendered on the same pixel since the screen precision is finite. Hence, you use a lot of resource for nothing! This article presents a fast 2D-line approximation algorithm based on the Douglas-Peucker algorithm (see [1]), well-known in the cartography community. It computes a hull, scaled by a tolerance factor, around the curve by choosing a minimum of key points. This algorithm has several advantages: 這是一個(gè)基于Douglas-Peucker算法的二維估值算法。

可連接SQL,ORACLE等數(shù)據(jù)庫。 首先建立SHOP用戶,密碼為SHOP,賦予連接和RESOURCE權(quán)限。再建立SHOP表空間,再建立表和觸發(fā)器(在SQL源代碼.doc里)并在PASSWORD表里添加新項(xiàng)name:‘a(chǎn)dmin ,psw: admin 這是管理員登陸帳戶。 剩余的就看幫助文件吧。

非常適合內(nèi)嵌式mp3播放,例如控制臺!注意看壓縮包里readme.doc 詳細(xì)過程,在ARM及MIPS下通過 新建一個(gè) wce application,選擇 a simple windows ce application 在 1.tool->options->directories>include files里包含必要的頭文件 D:\WINCE500\pubilc\directx\SDK\INC D:\WINCE500\pubilc\common\SDK\INC D:\WINCE500\pubilc\common\OAK\INC D:\WINCE500\pubilc\common\DDK\INC 2. >Library files D:\WINCE500\PUBLIC\DIRECTX\SDK\LIB\MIPSII\RETAIL D:\WINCE500\PUBLIC\COMMON\SDK\LIB\MIPSII\RETAIL D:\WINCE500\PUBLIC\COMMON\OAK\LIB\MIPSII\RETAIL 3.可能要在Project->Settings->link的object/library modules 加入 commctrl.lib coredll.lib ole32.lib oleaut32.lib uuid.lib strmiids.lib newres.h play.cpp play.vcw resource.h StdAfx.cpp StdAfx.h 下面為播放源碼 #include "stdafx.h" #include<dshow.h> #include<streams.h> .......其實(shí)編譯時(shí)的 object/library modules 只要看 sourse 文件包含哪個(gè)dll,或lib 就行

SimpliciTI™ -1.0.3.exe for CC11xx and CC25xx SimpliciTI is a simple low-power RF network protocol aimed at small (<256) RF networks. Such networks typically contain battery operated devices which require long battery life, low data rate and low duty cycle and have a limited number of nodes talking directly to each other or through an access point or range extenders. Access point and range extenders are not required but provide extra functionality such as store and forward messages. With SimpliciTI the MCU resource requirements are minimal which results in the low system cost.

WINDOWS調(diào)試工具很強(qiáng)大,但是學(xué)習(xí)使用它們并不容易。特別對于驅(qū)動開發(fā)者使用的WinDbg和KD這兩個(gè)內(nèi)核調(diào)試器(CDB和NTSD是用戶態(tài)調(diào)試器)。本教程的目標(biāo)是給予一個(gè)已經(jīng)有其他調(diào)試工具使用經(jīng)驗(yàn)的開發(fā)者足夠信息,使其能通過參考WINDOWS調(diào)試工具的幫助文件進(jìn)行內(nèi)核調(diào)試。本文將假定開發(fā)者熟悉一般WINDOWS操作系統(tǒng)和進(jìn)程的建立過程。 本文的重點(diǎn)是集成內(nèi)核模式和用戶態(tài)模式的圖形化調(diào)試器WinDbg。KD在腳本和自動化調(diào)試中更有用,并且在資深程序員中擁有一定地位,但是本教程將集中討論WinDbg,只會偶爾提到KD。 本文討論的是Windows NT 4.0,Windows 2000或以后的版本,而且目標(biāo)電腦的處理器基于X86架構(gòu)。對于64位平臺,將不會特別提及。 總之,本教程由簡單介紹調(diào)試器的安裝開始,大體分成2部分,基礎(chǔ)知識和選擇技術(shù)。基礎(chǔ)知識包括基本調(diào)試命令和常用調(diào)試命令。選擇技術(shù)是其他命令和在很多情況下都有用的調(diào)查方法。后者并不是調(diào)查象deadlocks, memory corruption或者resource leaks的唯一方法。第一次閱讀本教程,你可能會跳過選擇技術(shù)。你可以停止閱讀本教程而轉(zhuǎn)向微軟調(diào)試器討論組,也可以通過調(diào)試器的反饋e-mai解決更多的問題。
