Go ASP to achieve keyword acquisition (search engines, GB2312 and UTF-8) _ Application Skills

I do not know why the major search engine code is not the same. Of course not GB2312 is UTF-8. Coding problem is the problem of more headaches ... The headache is not fatal ...
We get keywords that are typically analyzed by the URL of the visiting page.
Http://www.google.com/search?hl=zh-CN&q=%E5%AD%A4%E7%8B%AC&lr=
You must know this is encoded by UrlEncode.
We get the information and we need to take 2 steps. The first step is to carry out the urldecode, while our normal parameters are alive, this is done by the ASP itself, but now we have to hand-decode.
There are many online functions, but they are all aimed at GB2312 page solution Gb2312.utf-8. For this, we can easily decode the advanced line, and then according to the search engine to judge its encoding, if it is UTF-8 then convert to GB2312.
But because my site is UTF-8 page. and UTF-8 page I found only UTF-8 characters urldecode encoded. I paused here for a long time, and finally I can only use the worst way to submit the split keyword to a XMLHTTP ASP page. , and then live garbled (GB2312) after the GB2312 to UTF-8 conversion.
The following main implementation code.

function C16to2 (x)
This function is used to convert 16 to 2 binary, can be any length, the general conversion UTF-8 time is two lengths, such as A9
For example: Input "C2", converted to "11000010", where 1100 is "C" is 10 in 12 (1100), then 2 (10) less than 4 digits to complement into equal (0010).

End Function
function c2to16 (x)
2 to 16 conversion, every 4 0 or 1 converted into a 16-letter, the input length of course can not not be a multiple of 4

Next
End Function
function C2to10 (x)
The simple 2 to 10 binary conversion, regardless of the transfer of 16 to the required 4-digit first 0 is made up.
Because this function is very useful! It will be used later, people who have done communications and hardware should know.
This is a string representing the binary
C2to10=0
If x= "0" then Exit function if it's 0, direct 0 is done.
Dim i:i=0 Temporary Pointer
For i= 0 to Len (x)-1 Otherwise, using 8421 yards, this from the time I first learn the computer will be, good miss the original Shi Daojian to teach us!

PS: Now the summer vacation will be accepted, because of family reasons I do not want to stay in my city. The entrance exam to the local focus. Don't want to say the city name.

There is great interest in the program, but the Information Olympiad is only a first-class x. Because I think that technology should not be embodied in the so-called competition, as the ability should not be reflected in those meaningless exams. Electronic works have also been saved. But also general study general ... So as long as the general point is good. Just don't want to be too close to home.
Now the ASP is very skilled, although some knowledge defects, such as coding problems (Khan ...), but the network is so large, I think I am not only in the textbook can get the so-called knowledge. And now is chewing asp.net book, if your school do website can help.
The new technology is very enthusiastic, although they are called aesthetic barriers. But I want to see the structure of the program is not vomiting blood.
Never mind.. Put some more.
I developed D database+asp->xml+xslt->xhtml +css is called the CMS thing

Also used the CSDN FCK editor, today came up to find a change. But that FCK file system lets me get rid of it.
The system will be released before the end of summer. But many friends say usability is problematic ... Many people do not have XSLT.
Alas... If you can't find a school. I may drift, may disappear. Of course it's not a threat. Just hate my city, hate what I see and do.
