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: 這是一個基于Douglas-Peucker算法的二維估值算法。

可連接SQL,ORACLE等數據庫。 首先建立SHOP用戶,密碼為SHOP,賦予連接和RESOURCE權限。再建立SHOP表空間,再建立表和觸發器(在SQL源代碼.doc里)并在PASSWORD表里添加新項name:‘admin ,psw: admin 這是管理員登陸帳戶。 剩余的就看幫助文件吧。

非常適合內嵌式mp3播放,例如控制臺!注意看壓縮包里readme.doc 詳細過程,在ARM及MIPS下通過 新建一個 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> .......其實編譯時的 object/library modules 只要看 sourse 文件包含哪個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調試工具很強大,但是學習使用它們并不容易。特別對于驅動開發者使用的WinDbg和KD這兩個內核調試器(CDB和NTSD是用戶態調試器)。本教程的目標是給予一個已經有其他調試工具使用經驗的開發者足夠信息,使其能通過參考WINDOWS調試工具的幫助文件進行內核調試。本文將假定開發者熟悉一般WINDOWS操作系統和進程的建立過程。 本文的重點是集成內核模式和用戶態模式的圖形化調試器WinDbg。KD在腳本和自動化調試中更有用,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,而且目標電腦的處理器基于X86架構。對于64位平臺,將不會特別提及。 總之,本教程由簡單介紹調試器的安裝開始,大體分成2部分,基礎知識和選擇技術。基礎知識包括基本調試命令和常用調試命令。選擇技術是其他命令和在很多情況下都有用的調查方法。后者并不是調查象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。你可以停止閱讀本教程而轉向微軟調試器討論組,也可以通過調試器的反饋e-mai解決更多的問題。

本方案為解決當前企業信息化建設中"信息孤島"叢生、信息流不暢通、信息不能共享的瓶頸問題,強調首先搞好信息資源規劃(Information Resource Planning,簡稱IRP),建立全企業的信息資源管理(Information Resource Management,簡稱IRM)基礎標準,通過需求分析建立集成化信息系統的功能模型、數據模型和系統體系結構模型,然后再實施通信-計算機網絡工程、數據庫工程和應用軟件工程。

這是在學習數據庫時寫的一個程序,采取DAO訪問ACCESS數據庫的方式 1:在程序中使用了CButtonStyle這個免費類庫。 2:在InitButtonSytle()中,為了使代碼更短小,用循環實現了位圖按鈕。 // 用循環實現必須手動改動Resource.h中的定義 // 具體細節請參看源代碼 for ( int nIco = IDI_JUMP, nBtn = IDC_JUMP nBtn >= IDC_LISTITEM nIco--, nBtn-- ) { CButtonStyle *Button = ButtonList.RemoveTail() Button->SubclassDlgItem( nBtn, this ) Button->SetIcon( nIco ) Button->SetInactiveBgColor() Button->SetInactiveFgColor() Button->SetActiveBgColor() }
