All properties of ActiveX controls are Unicode, with 16 bit wide characters, on the other side TCP/IP specifications are for byte streams.

The new version of IPWorks toolkit provides byte-array properties for all data sending properties such as DataToSend, EOL etc. The names of these byte array properties are derived from the base property by appending a 'B' such as DataToSendB, EOLB etc.

An example of use would be:

Dim A(0:5) as Byte 'remember to dim explicitly "0 to len-1"
For i=0 to 5
	a(i) = chr(127+i)
next i
IPPort1.DataToSendB = A

A similar problem arises when receiving data. In that case there's ONLY ONE byte-array property called DataInB property. It's the same name across all controls. The property is valid only inside the event. An example of use would be the following:

Private Sub IPDaemon1_DataIn(ConnectionId As Integer, Text As String, EOL As Boolean)
' the Text parameter contains the received data which, sometimes,
' may have been converted incorrectly -- especially in Unicode environments.
' the DataInB property has always the correct bytes.

Dim A() As Variant

' get the array's value when you first enter the event. -- VERY Important
with IPDaemon
A = IPDaemon1.DataInTextB

'only now you may manipulate it ...

Debug.Print Text

For I = LBound(A) To UBound(A)
  Debug.Print A(I)
Next I

End Sub
