Handling Binary Data with Byte Array Properties

When working with binary data, string-based properties may alter byte values due to encoding or character conversion. To preserve the original data, IPWorks components provide byte-array equivalents of common properties for both sending and receiving data.

Sending Binary Data

For properties that send data (such as DataToSend or EOL), corresponding byte-array versions are available by appending B (for example, DataToSendB, EOLB). These allow you to work directly with raw bytes.

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

Receiving Binary Data

When receiving data, string parameters (such as Text) may not accurately represent binary content. Instead, use the corresponding byte-array property (for example, DataInTextB) within the event to access the exact byte values.

Private Sub IPDaemon1_DataIn(ConnectionId As Integer, Text As String, EOL As Boolean)

Dim A() As Variant
A = IPDaemon1.DataInTextB  ' Capture bytes immediately

Debug.Print Text

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

End Sub
