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
success = False

Dim socket As New Chilkat.Socket

//  Connect to the server using TLS.
Dim bTls As Boolean
bTls = True
Dim maxWaitMs As Int32
maxWaitMs = 5000
success = socket.Connect("example.com",5000,bTls,maxWaitMs)
If (success = False) Then
    System.DebugLog(socket.LastErrorText)
    Return
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
    System.DebugLog(socket.LastErrorText)
    Return
End If

System.DebugLog("Received " + Str(bd.NumBytes) + " bytes.")
