ASP Programming Example: Using ASP to realize the operation of MP3 track information

Let's just say a little bit about MP3 's ID3 mark, because it's mainly about manipulating this thing.
MP3 at the beginning of the time we saw today, there are singers, times, albums and so on information
Only some simple parameters such as yes/no to indicate is not privated or copyrighted and other information, so MP3 related work brought a lot of inconvenience, 1996 when a foreigner proposed to add a piece of data after each MP3, to store the above information, Later on to become ID3 v1 as far as I know now is 1.1, specific or to check it yourself
Shanghai Cheng Kai Men's Hospital procedures: or old habits, with metadata to introduce DLLs, I have articles posted before, do not know please yourself to check
Look at the code
!--METADATA type= "TypeLib"
Uuid= "00000205-0000-0010-8000-00AA006D2EA4"

Function Convertbin (Binary)
' This function converts a binary byte to an ASCII byte.
For i = 1 to LenB (Binary)
Strchar = Chr (AscB (MidB (binary,i,1)))
Convertbin = Convertbin & Strchar
Next
End Function
