ASP program to write a complete IP location search class

Program

Fixed the Query method, the query method and the pursuit of the same; just chasing will automatically correct IP.
There is also a function of the writing error, has also been corrected;
Includes a validation function that adds the correctness of an IP address. (Just judging from the format)

' Disclaimer: This procedure uses the data for the network's famous IP tool software "Chase" author "Feng Zhihong"
Mr. ' meticulously collected and collated.
The conversion method of the "Hunt" database:
' Modify wry.dll file suffix name to wry.dbf
' Method One:
' Start Access data, select Open Database, and choose Open File Type ' DBASE 5 (*.dbf) '
' Open the Wry.dbf file and select the transform database in the Database utility under the Tools menu
' Select the Convert to Access 97 format (version optional) feature to save the file as an MDB format.
' Method Two:
' Use the Import and Export Data Wizard provided by SQL Server.
' Method Brief Description: Set the DSN pointing to wry.dbf in the ODBC Control Panel.
' Using the Import and Export Data Wizard, select the correct driver and the library you want to import.
' or import the MDB file generated by method one directly into the library.
' Method Three:
' Using access to open the Wry.dbf file automatically references the original library data through the MDB library.
'
' No other database platforms are installed, other methods are not considered.
