����ASP cannot work with real binary data (Safearray of bytes, VT_UI1 | VT_ARRAY ). But you can use multibyte string functions which enables work with byte array data. Most of the standard string functions (Mid, Left, Len, ...) have its multibyte twins (MidB, LeftB, LenB, ...).
����Although the functions are pure commented in ASP/VBS documentation, you can create and convert binary data from BinaryRead and BinaryWrite by the set of functions :
Multibyte functions, BinaryRead and BinaryWrite
����You can work with binary data from BinaryRead by the same way :
Real binary dataAlthough VBS cannot work with real binary data, you can use some free object to convert string data to binary. Stream_StringToBinary fuction lets you convert string to binary data using ADODB.Stream. Stream_StringToBinary returns real binary data - VT_UI1 | VT_ARRAY Variant type.
����To save/retrieve binary data from disk, binary file upload and download in ASP or better work with binary data (use any code page - ANSI, MAC, unicode UTF-8, search binary data, etc.) see Pure and Huge asp file upload.
