UTF-8使用纯真IP数据库乱码问题(已解决)
最近手头在写一个根据IP地址返回省份地区的代码,发现在使用纯真ip数据库的时候出现乱码,最后发现纯真数据库是居于GBK编码的,而我的整个工程编码都是采用的UTF-8编码,两个走到一起肯定会出现乱码,所以只能改写纯真读取ip的类

'得到访问者IP
public Function getip() 
		Dim strIPAddr 
		If Request.ServerVariables("HTTP_X_FORWARDED_FOR") = "" OR InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), "unknown") > 0 Then 
			strIPAddr = Request.ServerVariables("REMOTE_ADDR") 
		ElseIf InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), ",") > 0 Then 
			strIPAddr = Mid(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), 1, InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), ",")-1) 
			actforip=Request.ServerVariables("REMOTE_ADDR")
		ElseIf InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), ";") > 0 Then 
			strIPAddr = Mid(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), 1, InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), ";")-1)
			actforip=Request.ServerVariables("REMOTE_ADDR")
		Else 
			strIPAddr = Request.ServerVariables("HTTP_X_FORWARDED_FOR") 
			actforip=Request.ServerVariables("REMOTE_ADDR")
		End If 
		getip = Trim(Mid(strIPAddr, 1, 30))
