Description of the code: The reason for the use of ADODB.stream, because the content is not always achieve the desired effect, the position of EP is always much longer than expected, and I tried to use INSTRB,MIDB and other functions are also confusing results, so helpless under this unwise, Also hope master advice (ouch, how do I feel the acid does not slip the OH). Of course, only for the current location is valid, the other appropriate modification on the line, or even directly generate the page, and record to the database, become their own, with the above things to write a database should be enough.
It is not difficult to prevent the DLL from being downloaded, and for IIS to be an ISAPI extension with a. dll, the executable file can optionally be restricted to "null" by the action of a DLL file (anything, anyway, random input is OK.) ）。 If the DLL does not work for the outside station, it is afraid to talk nonsense. Prevent the news from being stolen against a method like this, check request. ServerVariables ("Http_referer") is not the site to coax out on it.
In addition, because I did not graduate from college, but also learn iron, so there must be a lot of rubbish place, please do not hesitate, thank you.
