if i understand your question correctly, you want to take pure binary code and change it to ascii. if that is correct, then this might help, but you will need to code it for your program (it gets explained at the end):

Public Sub unconvert(kk As String)
Dim tl As Integer
tl = (Len(kk) / 8)
Dim I As Integer

For I = 1 To tl
If I = "1" Then
buff = Mid(kk, I, 8)
Else
buff = Mid(kk, ((I - 1) * 8) + 1, 8)
End If

hh = buff
If Mid(hh, 1, 1) = "0" Then If Len(hh) > 1 Then hh = Mid(hh, 2, (Len(hh) - 1))
Select Case hh

Case 0: buff = Chr(0)

Case 11111110: buff = Chr(254)
Case 11111111: buff = Chr(255)
End Select
outbuff = outbuff & buff
Next I

End Sub

tl stands for total length, it verifys when you are done
i is the location of where it is decodeing
hh is a temporary string
buff is used as another temporary string
the colon is used to keep the cases on a single line instead of two
outbuff is the final result, it has to be declared in the general declarations

i hope this helps ya out
