How do I transfer binary data with your controls?


IPWorks 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
