概要:这个软件是三年前的时候在学校里写的,主要目的是给广大的Linuxers一个上网的机会,不过后来在我推出后官方又出了个Linux下的拔号二进制包。

PS:神州数码的局域网拔号软件在各大高校使用很多,有不少小区也是,一般官方发布的会有一定的限制。。。

熟悉802.1x协议的过程,对网络编程的学习也有一定的提高。
代码中的ASM汇编部分代码取自北航的高手xdkui(目前在MS就职),在此一并感谢他的努力hack。
声明:本代码只供学习使用,完全遵循计算机软件保护条例。

1.开发环境:

flex实时换肤术-动态切换CSS样式表文件

HTML中有一个非常好的特性就是可以动态切换页面链接的CSS样式表,而FLEX并不具备动态导入CSS的特性,因为FLEX的所有的UI外观都是在后台SERVER生成在发布到前台的(当然,通过AS可以实时更改UI外观setStyle,这是单个更改的方式,并不是实时的CSS文件切换),一直觉得挺不爽的,今天在mannu看到一个使用_global.styles来实现动态切换CSS文件的非常巧妙的方式:

首先,因为FLEX是将CSS编译进SWF文件的,所有我们将我们需要切换的CSS编译成SWF文件;

green.css Label{
color:#00FF00;
fontSize:20px;
}

green.mxml <?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml">

<mx:Style source="green.css"></mx:Style>

</mx:Application>

类似的还有red.css/red.mxml,blue.css/blue.mxml。 然后,我们要切换到相应的CSS就直接LOAD相应的SWF文件; 最后,将_global.styles设置为所导入的SWF文件的_global.styles 。 这里有一个工具封装好的工具类:

RuntimeStyle.as import mx.controls.Loader;
import mx.core.MXMLObject;
import mx.utils.Delegate;

class RuntimeStyle implements MXMLObject
{

private var _document:Object;
private var loader:Loader;

public function initialized(document:Object, id:String):Void
{ _document = document;
}

private var _source:String;

public function get source():String
{ return _source;
}

public function set source(value:String):Void
{ if (_source != value)
{ _source = value;

if (loader == undefined)
{ loader = Loader(_document.createClassObject(Loader,
"runtimeStyleLoader", 21983));
loader.width = loader.height = 0;
loader.addEventListener("complete",
Delegate.create(this, loader_complete));
}

loader.source = _source + ".swf";
} }

private function loader_complete(event:Object):Void
{ _global.styles = Loader(event.target).content._global.styles;
_document.styleName = _document.styleName == "!" ? "@" : "!";
}

}

测试代码:cssChg.mxml<local:RuntimeStyle xmlns:local="*"

source="{stylesWrappers.selectedItem.source}" />

<mx:Model id="alternateStyles"

source="alternateStyles.xml" />

<mx:ComboBox id="stylesWrappers"
dataProvider="{alternateStyles.stylesheet}"
labelField="name" selectedIndex="-1" />

alternateStyles.xml <?xml version="1.0" encoding="UTF-8"?>
<styles>

<stylesheet>
<name>red</name>
<source>red.mxml</source>
</stylesheet>
<stylesheet>
<name>green</name>
<source>green.mxml</source>
</stylesheet>
<stylesheet>
<name>blue</name>
<source>blue.mxml</source>
</stylesheet>

</styles>

    Wine 运行 Tm Pv4版本

    wget http://dl_dir.qq.com/qqfile/tm/tm2008preview4_sp2_chs.exe

    用wine运行安装程序: wine tm2008preview4_sp2_chs.exe
    安装完成后,并不能运行,缺少一些dll。将tm2008目录下SysDir目录下的各个子目录(Microsoft.VC80.ATL等5个子目录)下的所有dll文件拷贝到tm2008下的Bin目录中。将windows
    xp下的system32目录下的msxml3.dll, msxml3r.dll, riched32.dll,
    riched20.dll文件拷贝到.wine/drive_c/windows/system32/目录中。
    运行winecfg,在library标签页下,添加msxml3、riched32、riched20。
    然后就可以运行tm2008了。

    如果遇到中文乱码,注意做如下配置:
    1 如果用的英文locale,记得改成中文再启动wine。即export LANG=zh_CN.UTF-8
    2 配置中文字体。将windows下的simsun.ttc拷贝到~/.fonts/目录下,然后运行regedit,修改HKEY_LOCAL_MACHINE\Software\Microsoft\Windows
    NT\CurrentVersion\FontSubstitutes\ 下的所有键值,将他们都改成SimSun。

    Ubuntu 7.10 安装wine记录

    cz@cz-desktop:~$ wget -q http://wine.budgetdedicated.com/apt/387EE263.gpg -O- | sudo apt-key add -
    OK
    cz@cz-desktop:~$ sudo wget http://wine.budgetdedicated.com/apt/sources.list.d/gutsy.list -O /etc/apt/sources.list.d/winehq.list

    cz@cz-desktop:~$ sudo apt-get update

    cz@cz-desktop:~$ sudo apt-get install wine

    64位ubuntu wine1.0 安装qq

    环境比较特殊 注意是64的i386就不要看了
    {安装wine:}
    1.添加签名
    wget -q http://wine.budgetdedicated.com/apt/387EE263.gpg -O- | sudo apt-key add -
    2.更新WINE源
    sudo wget http://wine.budgetdedicated.com/apt/sources.list.d/hardy.list -O /etc/apt/sources.list.d/winehq.list
    3.更新软件包
    sudo apt-get update
    4.安装WINE
    sudo apt-get install wine

    {设置wine:}

    Wine快速设置 deb包 for amd64的下载地址是:

    http://ubuntu-tweak.googlecode.com/files/wine-ubuntu_amd64.deb

    顺便再加上之前的for i386的:

    http://ubuntu-tweak.googlecode.com/files/wine-ubuntu.deb {使用QQ} Wine的版本:
    Wine 1.0 (默认中文补丁,有打过补丁的Wine1.0下载,见下面)
    windowssux已经把8.04-32bits的deb包(包括中文补丁)做出来了,在http://ftp.ubuntu.org.cn/home/windowssux/Wine-CN/
    登录的用户名和密码在http://forum.ubuntu.org.cn/viewtopic.php?t=9685

    Wine的注册表 修改过的内容如下,请给这个文件保存成QQ2007.reg
    REGEDIT4
    [HKEY_CURRENT_USER\Software\Wine\AppDefaults\QQ.exe]
    "Version"="vista"
    [HKEY_CURRENT_USER\Software\Wine\AppDefaults\QQ.exe\DllOverrides]
    "riched20"="native"
    "riched32"="native"

    并使用下列命令导入
    #regedit QQ2007.reg

    替换DLL文件 需要的 dll:: mfc42.dll msvcp60.dll 给上面的这二个dll放到~/.wine/drive_c/windows/system32/目录中
    下面下载的那个qq2007beta1kb5_0.0.2007_x86.tgz中也有,也可以从windows的系统中找

    安装方法 下载:http://linuxfire.com.cn/~huahua/zero/qq2007beta1kb5_0.0.2007_x86.tgz 解压后,只使用这个中的那个QQ,原wine之类的配置文件不要了.

    运行 可以建一个下面这样的快捷方式,注意修复你的路径为你自己的.
    env WINEPREFIX="/home/fukai/.wine" wine "Z:\home\fukai\qq2007beta1kb5\QQ\QQ.exe"

    在安装和使用程序时的注意事项 现发现的bug有快捷键不能用,视频有时会死机,传文件之类都非常正常

    ==================
    有空的时候再研究下一键安装 linux qq
    为今天听到的马化腾说linux qq是假消息的消息默哀
