There are at least three ways to convert binary data, such as the data you get from the ASP's Request.BinaryRead method, to a string.
First: The multibyte method using the VBS
Instance:
Function simplebinarytostring (Binary)
' Simplebinarytostring converts binary data (Vt_ui1 | Vt_array Or multibyte string)
' To a string (BSTR) using multibyte VBS functions
Dim I, S
For I = 1 to LenB (Binary)
s = S Chr (AscB (MidB (Binary, I, 1))
Next
simplebinarytostring = S
End Function

" and "might. both of these words indicate that things may happen in the future and can be exchanged in sentences. for example, Peter may be a professional player in the future. you can also say that: Peter might become a professional player.
Well, let's do a set of exercises. all the exercises are about Peter's future achievements. now, we ask the English teacher to propose a sentence using the word "may", and ask the students to use the word "might" instead. when students are doing exercises,
