   | No sir, the GetData is somewhat like the Get/Input statements.  They   
   | require "sizing" to the amount of data to be received, and a ByteArray   
   | is just fine for this purpose.

   Good theory, but in fact incorrect. The examples in MSDN use unsized   
   strings, for instance, to receive text data, which gives a hint.   
      
   The following does work for receiving 4 bytes of data:   
      
   Private Sub Winsock3_DataArrival(ByVal bytesTotal As Long)   
       Dim bytes() As Byte   
       Dim n As Integer   
      
       Winsock3.GetData bytes, vbArray + vbByte   
       For n = LBound(bytes) To UBound(bytes)   
           Debug.Print n, bytes(n)   
       Next n   
      
   End Sub   
      
   If you replace the Dim statement with   
       Dim bytes(0 to 3) As Byte   
      
   the bytes will remain all zero.
