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 fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

success = 0

set socket = CreateObject("Chilkat.Socket")

'  Connect to the server using TLS.
bTls = 1
maxWaitMs = 5000
success = socket.Connect("example.com",5000,bTls,maxWaitMs)
If (success = 0) Then
    outFile.WriteLine(socket.LastErrorText)
    WScript.Quit
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.
set bd = CreateObject("Chilkat.BinData")
success = socket.ReceiveBdN(256,bd)
If (success = 0) Then
    outFile.WriteLine(socket.LastErrorText)
    WScript.Quit
End If

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

outFile.Close
