��Z��么安装ubuntu 12.04.3 wubi找不到镜像！�Q�！

Wed, 18 Dec 2013 14:46:00 GMT

如题我也不知道�ؓ什么？�Q?br />我开始下�?2位的�Q�然后把里面的wubi拯��出来�Q�坑爹尽然是12.04.1 所以找不到。�?br />然后我到�|�上�?2.04.3 32位，。。。�?找不到。。。。。。到官网只能64位。。�?br />后面只能下蝲64为用�q�个wubi 安装成功。。�?br />不容易啊。。。。�?img src ="http://www.shnenglu.com/xvsdf100/aggbug/204880.html" width = "1" height = "1" />

�q�个问题我是在论坛看到的�c�M��的问题，当时回复了他。。后面仔�l�想惛_��好像自己也不是太清楚。如是又看了一下tcp/ip详解。。。�?br />��Z��自己做了一下实验，发现发送一些数据后客户端就卡死了（��d��套接字）�Q�服务器只接受连接，不取出系�l�缓存的数据�?br />
我想估计是服务器的对应套接字的buffer用完了，所以内�怸�在接收数据了�Q�导致客��L��不能够发送数据。那�q�样看来�Q�客��L��想不停的发送数据，只有不断建立�q�接才可以，在一个连接不停发送数据是不能的事情�?br />
后面看了一下buffer �?�H�口大概�c�M��Q�但不等于一会事�?br />比喻本机上窗口是25000�Q�但接收buffer 8192.. 而且看tcp/ip 2貌似buffer�q�是可以提高他的上限�?br />
以前觉得socket send 貌似��q��于tcp/ip协议�Q�现在看来真好傻�Q�好天真。�?br />socket 函数只是插口层。。以前不明白��Z��么插口，现在明白了，��是用应用层钥匙�Q�通过�q�把钥匙来跟下面协议打交道。�?br />

只要接触�q�c/c++�|��\�~�程人都可能会知道select io 模式�Q�网�l�书�c�都�?fd_set {int num; SOCKET arr[64]} 有所限制�Q�因为数�l�的长度只有64�Q�那么超�q?4你就不能放，要么你就是用多线�E�分别实用select.�?br /> 一些书�c�通过改定义宏使数�l�的长度变长�Q�但也不实用�Q�不能动态的变化�Q�我��M��能定一个非常的长的长度�Q�毕竟是在栈上�?br /> 我就在想那么select完全只能在客��L��使用�Q�而且套接字还不能��过64。那�q�不��是一个��Y肋吗�Q�？一直对�q�个有一个迷惑。。。。�?br />
后来�Q�自��q��C��libevent的源代码发现他也用的是select。。看别�h说这个库�Q�轻��L��村֤�理上万个套接字，我就在想select不是有限制吗�Q�？他是怎么做到。。。。。�?br /> 看了源代码，我明白了。他只是用对上存放SOCKET的句柄。。我们看一下他的新定义�l�构体�?br />

struct win_fd_set {

u_int fd_count;

SOCKET fd_array[1];

};

�q�个��是新定义结构体�Q�跟原来�E�微有点变化只是�?4改�ؓ1�Q�有些同学可能见多很多这��L��写法�Q�这�U�写法我也在一些项目��用了。这�U�写法可以fd_array动态变化�?br /> win_fd_set * Set = (win_fd_set*)malloc(sizeof(win_fd_set) + sizoef(SCOEKT) * 10);
Set->fd_array 可以�?1 �?SOCKET�Q�因为我的内存大��够放11个SOCKET�?br /> 误��住内存是没有数据格式�Q�只要��够大��，随便你怎么放。数据格式只是方便我们管理和处理数据而已�?br /> �q�样��p��?4个大��限制。。我其实一直很好奇��Z��么中国书�c�都是一��L��Q�libevent已经出来好久了，但也没有看到有�h说这一点，可能是高手们都不屑�?br /> 现在渐渐喜欢看开源的代码�Q�不喜欢看书�c�了�Q�喜�Ƣ在代码中学习他们是怎么�l�织一个好��目�?br /> 有时候感慨：高手用c 写着漂亮的c++代码�Q�而我�{�菜鸟却用c++ 写丑陋的c代码。�?/span>

我顺便把他整个定义结构和函数�l�大家脓出来�Q�免大家�q�要自己��M��libevent�Q�不�q�推荐没有看�q�libevent同学�Q�可以稍微看一下�?br />

因�ؓ我安装了ObjectArx Wizard 所以就会在创徏工程时候出现ObjextArx �Q�然后选择�Q�输入你的工�E�名点击��定�?br /> 我们会看��C��个要你选择界面�?br />

�q�样一个ObjectArx的工�E�就创徏好了�Q�现在就开始我们写代码了�?br /> �q�个cpp 里面�c�d��相当于我们c/c++ main 函数�?br /> 其实�l�我感觉��和mfc才不多，只是把main ��装在最里面�Q�我们MFC开发时候也是看不到main�Q�我们的代码��是在一个类里面写。所以这里也差不多的�?br /> 我们可以看出�q�段代码�Q?span style="font-size: 13px; color: #008080;"> 1 virtual AcRx::AppRetCode On_kInitAppMsg (void *pkt) {

�q�个2个函数显然是一个初始化�Q�加载时候）�Q�一个卸载时候调用的�?br />
现在我们开始添加代码。来打印hello world
在virtual AcRx::AppRetCode On_kInitAppMsg (void *pkt)函数中添加一�?nbsp;acutPrintf(L"hello world");

然后我们我就可以导入cad�q�行��试了�? 打开对应版本的cad ,如果你是ObjectArx 2012那么你就只能用cad 2012.我不知道��Z��么cad不向下兼宏V��?br />在cad命��o框里面输入APPLOAD,然后选择到我们生成的arx�?br />让后cad命��o框就出现�Q�命�? APPLOAD

hello world已成功加�?CadHelloWorld.arx�?br />看见��C��q�hello world.

Autocad ObjectArx开�?---------->环境搭徏

以前是做��q��autocad的环境下能够生成dwg�?我们那时候用Teigha �q�个库，貌似是国外一个公叔R��过对Autocad反汇�~�得出来的，不过跟ObjectArx比较�怼�。但Teigha��装非常好�?br />
开始环境简单搭建和可能遇到的问题�?br />
1�Q�可以去�q�个论坛下所有版本的Arx http://www.objectarx.net/forum.php

2: 如果你下载的2010版本以上压羃包里面没有Arx Winzard �q�样你的vs��没有对应Arx的引��|��非常不方�ѝ�?虽然我们可以完全自己创徏一个这样工�E�，
我可能去cad 官网��M��Q�http://usa.autodesk.com/adsk/servlet/index?siteID=123112&id=1911627

3�Q�如果你vs中ObjectArx工具条不昄��图标的话�Q�可以百度一下忘记是在哪个网站下载了�Q�要豆豆的网站。然后解压到对应文�g夹名字就可以了�?br />
cad安装问题�Q?br />cad软�g安装安装不上也是一�U�比较常见问题�?br />我就用半天时间才装好�Q�装好我都不知道具体用哪个方法装好的。我通过癑ֺ�和自己分析一般cad 装不好的原因��只有几个�?br />1�Q��\径不能含有中文�?br />2�Q�你的cad名字太长�?br />3�Q�vc 2005 �q�行�?安装不上�?-----------------》我��是�q�个问题�?我的cad在安装第三方库时候��L��p�|�Q�我觉得大多数都应该是运行库安装��p�|引�v�Q�你最好先把vc2005卸蝲掉，然后单独重装�Q�如果没有报错的话，应该��没有问题了�?br />
书籍�Q�ObjectARX开发实例教�E?---张帆�? 貌似我就看到�q�样一本书�c�，但这本还是显得太老了。貌��D��的arx 2004版本。这样就��D��里面一些内�Ҏ��们根本就不能按照里面做了�?br />所以接下来几篇文章��是怎么用vs2008 �?arx 20012来开发几个常见界面插件了�Q�相当于一个整理，因�ؓ我上周才�׃��天时间学习ObjectArx 开发，所以我遇到的问题大多�h开始学习都会遇到的�?img src ="http://www.shnenglu.com/xvsdf100/aggbug/204202.html" width = "1" height = "1" />

IDL接口或许你会遇到一个挺无语的地�?-----》关键字

Tue, 25 Jun 2013 09:34:00 GMT

我应该快有一�q�工作经验，虽然毕业才没有几天�?一炚w��不伤感，因�ؓ没有感觉�Q�一直都在工作�?br />我的工作前段旉��主要�l�写IDL接口�Q�下个月开始投向GIS开发）�Q�主要是AUTOCAD的接口，我公司用teigha的库�?br />不得不说代码写的真的漂亮�Q�帮助文档也写的很好�?br />
IDL 资料本��n��很��，IDL 接口资料��几乎就一本老外的书�c�，而且版本比较老了�Q�所以难度还是有一点的�?br />我现在对IDL接口应该是比较熟�l�，如果你遇��C��些问题，可以问我�Q�maybe我是知道的�?br />
好了�Q�说一下正题�?br />在IDL中大量��用关键字�Q�所以我们在开发IDL接口当中用到关键字也是非常多的�?br />
我就不分析关键字的原理了�Q�因为快要下班了�?br />最新版关键字用法和以前老版本不一��h��以需要注意�?br />例子代码在帮助文档有�?br />
现在我觉一个例�?br />现在我们定义关键字的IDL_KW_PAR
static IDL_KW_PAR kw_pars[] = {
{“BLOCK”�Q�IDL_TYP_STRING�Q?,0,(int*)IDL_KW_OFFSETOF(block_there),(char*)IDL_KW_OFFSETOF(Block)},
{"INDEX",IDL_TYP_LONG,1,0,(int*)IDL_KW_OFFSETOF(index_there),(char*) IDL_KW_OFFSETOF(index),
{NULL}
};

�q�里��定义好�?IDL_KW_PAR.
注意一个问题，BLOCK �?INDEX 定义��序有讲求�?br />你必��要把BLOCK攑ֈ�INDEX上面�?br />因�ؓB < I �?br />如果没有按照�q�样��序声明你就使用关键字就会出��C��能分配关键字�?br />因�ؓ�q�个必须按照 in LEXICAL order �Q�词法顺序来弄）�?br />你会觉得�q�个非常好笑�Q�但却是是这��L��Q�这个在idl help 里面是没有说明的�?br />�q�个是我在分析export.h 发现问题解决�Ҏ��?br />

我就��单说到这里吧�?br />
如果你想知道IDL 怎么在结构体里面传�?IDL_VPTR 或�?怎么�q�回动态的数据或�? === 或�?一些DWG的东西也可以找我哦�?br />其实我想说我擅长�|�络开发行不呢�Q�！�Q�！�Q?br />My QQ ��：274301756
速度下班�Q�我IT 但我从来不加班。。�?img src ="http://www.shnenglu.com/xvsdf100/aggbug/201301.html" width = "1" height = "1" />

看过很多�|�络书籍 �?�~�程书籍�Q�突然发现自�׃��来没有实现模拟TCP三次握手�?br /> ��p��steven也只是用抓包�E�序说明一下�?br /> 我一直觉得实践只��验真理的唯一标准�Q�如是就开始自��p��验�?br /> 我开始准备用原始套接字来解决�q�个问题�Q�但是微软已�l�在xp�Q�含XP�Q�以后就不在支持发送原始TCP。（貌似�|�上有�h反汇�~�，扑ֈ��q��o的代码。）
心里一下就被打入谷底了�?br /> 不过�H�然惌��似可以用驱动发送数据包�Q�而且我以前用winpcap写过一个ARP��d��软�g�Q�所以发送数据包的问题解决了�?br /> 但接�t�过来问题又来了�Q�我用winpcap发送数据包�Q�应用层没有对应的程序，所以windows�pȝ��会自动发送RST来终�l�我的链接�?br /> 链接都终止我握个屁的手啊�?br />
瞬间心碎了，但哥没有攑ּ�。又惌��v哥自学过驱动开发，了解�q�网�l�驱动拦截，惌��v了NDIS 中间层数据包�q��o�?br /> 我直接简单修攚w��个代�?实现我拦截RST �?老子拦截了你�Q�你��发吧�?br /> �q�些准备工作完成了�?br />
看看我写的核心部�?--�?�ơ握�?加上一个消息发�?�Q�测试用的是以前自己写TCP聊天�E�序�Q�自己可以写一个TCP聊天�E�序�Q�不惛_��的话��q��www.baidu.com来练习也可以�Q��?br /> 自己装B的用C++ �c�d��装一下协议�?br />
