I have been asked this question several times and finally dug into the system to make it work.

The solution

The Office Assistant relies on some "agent" technologies.  To fix this we need to install the agent technologies and then copy a DLL across.  Since I was playing around it is possible that there is an extra step or two that is not actually needed, but since this is a small process and simple to do I don't think it will do any harm.  What is more, I was not about to rebuild a system, load Vista and Office 2003 just to see if I could remove a 10 second step :-)

1. Download the MSAgent technology from http://www.microsoft.com/msagent - select the CORE files, so for me that was this item - Download the Microsoft Agent core components (395 KB exe) Download the MSAgent2.exe file from http://www.microsoft.com/downloads/details.aspx?FamilyID=E11BF712-7862-45BA-826D-44AE3A11836F&displaylang=en
2. Run the download, accepting the UAC prompt (the security prompt)
3. - select the option "This program installed correctly"
4. Open an elevated command prompt - have a look at How to start an administrative (or elevated) command prompt and tell if you got it right (in Vista) if you are unsure how to do this
5. type the following commands into the prompt (each line will probably start with "c:\windows\system32>" - don't worry about this (if you are using a x64 system replace system32 with system)

   copy c:\windows\msagent\agentdpv.dll c:\windows\system32 regsvr32 c:\windows\msagent\agentdpv.dll

6. That is it.  If the last item failed then check you have a elevated command prompt

How I diagnosed the problem and fixed it - only read if you want to know more - technical stuff!!

This is a simple example of using the great tools provided by Microsoft.  The stages I took

1. Download Process Monitor from http://www.microsoft.com/technet/sysinternals/ProcessesAndThreads/processmonitor.mspx
2.   Run Process Monitor and for every application on the list (except winword.exe), right click on it and select Exclude by Process Name
3. Clear the history by pressing Ctrl+X
4. Now do the "thing" that is causing the problem, so in my case, opening the gallery for the office assistant
5. To stop the logging going on forever, stop the logging once you have reproduced the problem (Ctrl+E)
6. Now go down the list and look for things that failed - if you see a number of retries, or in this case, an attempt to open a particular file in every directory on the path then you know you have your suspect
7. Open an elevated command prompt and type the following:
   1. CD C:\
   2. DIR /S /A <filename> - so DIR /S /A agentdpv.dll
8. You will see several hits, but ignore the ones in places like c:\windows\system32\winsxs or other strange locations - c:\windows\msagent seemed like a good option to me.
9. We now need to register the file:
   1. regsvr32 <filename> - so regsvr32 c:\windows\msagent\agentdpv.dll
10. Finally either add c:\windows\msagent to the path or you can try the trick I did of copying it to c:\windows\system32

100 Words Every High School Graduate Should Know

美国Heritage的编辑们精心编辑了100个单词。他们认为，这100个单词对于高中毕业生来说，虽然无法做到完全翔实地反映语言水平，但仍然是一个很好的评判标准。

“我们选择的单词，如果你知道如何正确运用，那么你将在语言方面没有问题” - 主编Steven Kleinedler（awflasher）

以下是100个单词：

vi/vim 中可以使用 :s 命令来替换字符串。以前只会使用一种格式来全文替换，今天发现该命令有很多种写法（vi 真是强大啊，还有很多需要学习），记录几种在此，方便以后查询。

:s/vivian/sky/ 替换当前行第一个 vivian 为 sky

:s/vivian/sky/g 替换当前行所有 vivian 为 sky

:n,$s/vivian/sky/ 替换第 n 行开始到最后一行中每一行的第一个 vivian 为 sky

:n,$s/vivian/sky/g 替换第 n 行开始到最后一行中每一行所有 vivian 为 sky

n 为数字，若 n 为 .，表示从当前行开始到最后一行

:%s/vivian/sky/（等同于 :g/vivian/s//sky/） 替换每一行的第一个 vivian 为 sky

:%s/vivian/sky/g（等同于 :g/vivian/s//sky/g） 替换每一行中所有 vivian 为 sky

可以使用 # 作为分隔符，此时中间出现的 / 不会作为分隔符

:s#vivian/#sky/# 替换当前行第一个 vivian/ 为 sky/

:%s+/oradata/apras/+/user01/apras1+ （使用+ 来 替换 / ）： /oradata/apras/替换成/user01/apras1/

1.:s/vivian/sky/ 替换当前行第一个 vivian 为 sky

:s/vivian/sky/g 替换当前行所有 vivian 为 sky

2. :n,$s/vivian/sky/ 替换第 n 行开始到最后一行中每一行的第一个 vivian 为 sky

:n,$s/vivian/sky/g 替换第 n 行开始到最后一行中每一行所有 vivian 为 sky

(n 为数字，若 n 为 .，表示从当前行开始到最后一行)

3. :%s/vivian/sky/（等同于 :g/vivian/s//sky/） 替换每一行的第一个 vivian 为 sky

:%s/vivian/sky/g（等同于 :g/vivian/s//sky/g） 替换每一行中所有 vivian 为 sky

4. 可以使用 # 作为分隔符，此时中间出现的 / 不会作为分隔符

:s#vivian/#sky/# 替换当前行第一个 vivian/ 为 sky/

5. 删除文本中的^M

问题描述：对于换行,window下用回车换行(0A0D)来表示，Linux下是回车(0A)来表示。这样，将window上的文件拷到Unix上用时，总会有个^M.请写个用在unix下的过滤Windows文件的换行符(0D)的shell或c程序。

· 使用命令：cat filename1 | tr -d “^V^M” > newfile；

· 使用命令：sed -e “s/^V^M//” filename > outputfilename。需要注意的是在1、2两种方法中，^V和^M指的是Ctrl+V和Ctrl+M。你必须要手工进行输入，而不是粘贴。

· 在vi中处理：首先使用vi打开文件，然后按ESC键，接着输入命令：%s/^V^M//。

· :%s/^M$//g

如果上述方法无用，则正确的解决办法是：

· tr -d "\r" < src >dest

· tr -d "\015" dest

· strings A>B

6. 其它

利用 :s 命令可以实现字符串的替换。具体的用法包括：

:s/str1/str2/ 用字符串 str2 替换行中首次出现的字符串 str1

:s/str1/str2/g 用字符串 str2 替换行中所有出现的字符串 str1

:.,$ s/str1/str2/g 用字符串 str2 替换正文当前行到末尾所有出现的字符串 str1

:1,$ s/str1/str2/g 用字符串 str2 替换正文中所有出现的字符串 str1

:g/str1/s//str2/g 功能同上

从上述替换命令可以看到：g 放在命令末尾，表示对搜索字符串的每次出现进行替换；不加 g，表示只对搜索

字符串的首次出现进行替换；g 放在命令开头，表示对正文中所有包含搜索字符串的行进行替换操作。
