I don't know if this is what you needed or not, but you can assign a sting 
to a byte array, just remember that the array will have the ascii value of 
the characters, and that they are seperated so you will go every other 
entry in the byte.  A real simple example is 

Private Sub Form_Load()
Dim str As String
Dim bytstr() As Byte
Dim i As Integer

str = "abcdefg"
bytstr = str
For i = 0 To UBound(bytstr) Step 2
MsgBox Chr(bytstr(i))
Next i

End Sub

hope this helps,
