文摘: MSN / QQ 中的动画表情 在Delphi中RichEdit的实现。

相信用过QQ、MSN中的动画表情对我们的吸引力了吧。在前几天我的一个小应用中需要添加这样的一个功能，首先从网上下载了RXLib2.75(包括RxRichEdit)，安装后测试了一下它提供的例子$(DELPHI)RXDemoRICHED2Richedit.dpr，在使用插入GIF图片时我发现了一个严重的问题：就是GIF图片是不会动的。因为原来对COM这些技术接触较少，只有上网查询资料，首先我去了大富翁www.delphibbs.com查找，不过没有查到，后来终于在网上查到了dtianx大侠的资料(见文章前面的链接)，不过我发现他提供的代码是C++下的，于是把这些代码转换了一下，使其在Delphi下也能用。 ...

xplorer2中x2tips的汉化方法

下载了Snoppy汉化的xplorer2-1.1.0.3(我已经懒得维护自己的“不完全汉化版”了)，发现x2tips还是没有汉化，倒是另外提供了一个HLP文档，内容完全是x2tips里面的。也许是他不知道怎样汉化，毕竟这个需要一点技巧。

1. 先翻译x2tips.rtf(这个其实他已经做了)

2. 然后将翻译后的x2tips.rtf用文本编辑器打开，删除RTF头和每条tips之间多余的par，另存为x2tips.txt
(x2运行时读取的是这个文件)

3. 然后用reshacker等工具打开xplorer2.exe，在string table中可以找到一个rtf头
11260,
"{rtf1ansiansicpg1252deff0deflang2057{fonttbl{f0fmodernfprq6fcharset134
'cb'ce'cc'e5;}{f1fswissfprq2fcharset0
Verdana;}{f2fswissfprq2fcharset134
'cb'ce'cc'e5;}{f3fmodernfprq1fcharset0 Courier
New;}{f4fmodernfprq1fcharset134 'cb'ce'cc'e5;}{f5fnilfprq2fcharset134
'cb'ce'cc'e5;}}n{colortbl
;red0green0blue255;red255green0blue0;}nviewkind4uc1pardlang2052bf0fs26'c4'e3'd6'aa'b5'c0'c2'f0lang2057f1
...b0fs18parnparn"

x2运行时实际是从x2tips.txt中抽取一条，然后在前面添加这个rtf头，放到对话框中显示的

按RTF的要求，需要在这个头中声明后面文本需要用到的字体和颜色
一个简单的做法就是将前面翻译后x2tips.rtf的RTF头拷贝过来

11260,
"{rtf1ansiansicpg1252deff0deflang2057{fonttbl{f0fmodernfprq6fcharset134
'cb'ce'cc'e5;}{f1fswissfprq2fcharset0
Verdana;}{f2fswissfprq2fcharset134
'cb'ce'cc'e5;}{f3fmodernfprq1fcharset0 Courier
New;}{f4fmodernfprq1fcharset134 'cb'ce'cc'e5;}{f5fnilfprq2fcharset134

...b0fs18parnparn"

我这里将f0和f2字体改成了宋体('cb'ce'cc'e5)

Total Commander 6.50出来了

还在家里过年，发现Total Commander已经推出了6.5版本
这个工具从来没有让我失望，但我正觉得xplorer2的一些功能不错时，Total Commander里面也有了，而且做的更好

比较重要的新功能有:

• 缩略图方式(thumbnail view, 这下xplorer2不能专美了)
• 自定义显示栏目列表(Custom columns mode, 也是xplorer2提供了但tc原来没有的)
• 内容插件接口(Content plugins)，可以通过插件提取文件的描述信息，比如从mp3的tag从读取作者、歌名, 并且可以用于搜索(比xplorer2的接口要强大, 它只能利用系统插件，开发起来也比较麻烦)
• 自动安装插件

New in Total Commander 6.50:

- Thumbnail view: Display of miniature pictures for images and some other file types
缩略图方式，这下xplorer2不能专美了
- Custom columns mode: Up to 29 different user-defined view modes with custom columns
自定义显示栏目列表, 也是xplorer2提供了但tc原来没有的
- Content plugins: Display+Search for additional file properties, use in multi-rename tool
内容插件接口，可以通过插件提取文件的描述信息，比如从mp3的tag从读取作者、歌名
并且可以用于搜索--比xplorer2的接口要强大(它只能利用系统插件，开发起来也比较麻烦)
- Overlay icons for special file types like LNK files (configurable)
- Automatic installation of plugins and languages when opening plugin archive (if supported by the plugin)
自动安装插件
- New configuration page for configuring all plugin types
- Alt+Shift+F3 loads lister without plugins and any multimedia additions
- Shift+button click on current directory switches to the dir part on which you clicked
与xplorer2类似的功能: 标题上的路径可以分段点击(不过视觉效果不如x2)
- Shift+button click in search on 'go to file' or 'feed to listbox' opens dir in new tab
- Search for NTFS-encrypted files
- Define different location of tree content files (treeinfo.wc)
- Show current speed also when copying in synchronize dirs function
- FTP: Support for MODE Z compressed uploading/downloading
- New type of locked tab: still allows to change dirs, but reverts to tab-root when clicking "" or switching to other tab
允许改变目录的锁定标签页
- Multi-rename tool: Multiple search+replace, search+replace history, button to reload rename results
- F5 - F2 now transfers in background also for FTP uploads+downloads
- New pseudo environment variables supported in path names, pointing to locations of virtual folders:
%APPDATA%,
%DESKTOP%, %PERSONAL% (My Documents), %PROGRAMS%, %STARTMENU%, %FONTS%,
%STARTUP% (use lowercase to access env vars with these names)
- New
internal commands (for button bar, starter menu and user-defined
hotkeys) to change drives: cm_GotoDriveA..cm_GotoDriveZ,
cm_GotoNextDrive and cm_GotoPreviousDrive
- New internal commands cm_srcactivatetab1..10 activates tab 1-10 in source panel, similar for target panel.
-
Subdir filters now also work when copying (only files of this type).
Syntax: Include: somedir1 somedir2 Exclude: *.* | somedir1 somedir2
-
Synchronize dirs: Also allow to set copy direction of equal files (via
right click menu only!), e.g. for copying them to a different location
- Remember special display modes (thumbnails, comments, custom columns) separately per tab, and when closing
- The complete list can be found in history.txt

Vim Tip #118: Configure gVim as Internet Explorer 'View Source' editor

http://vim.sourceforge.net/tips/tip.php?tip_id=118

The reason:
- Hated it when the file was "Too big for notepad" :)
- syntax highlighting

Key point:
1. How to make gvim the IE's 'View source' editor
2. How to let it auto syntax higlighting, as the temporary file might has no extension.

Answers:
1.

REGEDIT4 [HKEY_LOCAL_MACHINESOFTWAREMicrosoftInternet ExplorerView
Source EditorEditor Name] @="c:Program Filesvimgvim.vbs"

Here's
another problem: "Unfortunately, you can't specify a quoted filename
argument here, i.e. "%1". The editor specified is supposed to handle
filenames which contain spaces(which come from 'Temporary Internet
Files') ."(seems that IE6 doesn't have this limitation). Thus we
need a vbs wrapper (or a shortcut with arguments specified) to quote
the argument.

2. gvim -c syntax=html
