Receive an Exact Number of Bytes into a BinData

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveBdN, which receives exactly the requested number of bytes and appends them to a BinData, continuing until the full count is satisfied.

Dim success As Boolean = False

Dim socket As New Chilkat.Socket

'  Connect to the server using TLS.
Dim bTls As Boolean = True
Dim maxWaitMs As Integer = 5000
success = socket.Connect("example.com",5000,bTls,maxWaitMs)
If (success = False) Then
    Debug.WriteLine(socket.LastErrorText)
    Exit Sub
End If


'  MaxReadIdleMs controls the inactivity limit for receiving.  The ReceiveBdN call will fail if
'  incoming bytes halt for longer than this many milliseconds before the full amount is received.
socket.MaxReadIdleMs = 15000

'  Receive exactly the requested number of bytes, appending them to a BinData.  The method continues
'  receiving until the full count is satisfied or a failure occurs.
Dim bd As New Chilkat.BinData
success = socket.ReceiveBdN(256,bd)
If (success = False) Then
    Debug.WriteLine(socket.LastErrorText)
    Exit Sub
End If

Debug.WriteLine("Received " & bd.NumBytes & " bytes.")
