I have a Windows Service application that acts as if it's an SMTP server.
Outlook connects to this service, which is always running on the localhost.
This works fine most of the time.
However, sometimes it will no longer receive anything from Outlook.
Socket.Receive would block indefinitely (actually, Socket.Poll times out,
because that's what I'm using). Outlook sends it, because when I'm stepping
through the code with the debugger,...

Hi
I listen on a port, when data is received I raise an event
(OnMessageReceived) in the while loop as follows:
private void WaitForConnection() {
TcpListener listener = new TcpListener(IPAddress.Any, 1234);
Stream data = null;
Socket socket = null;

Hi!
I have simple client/server game that uses sockets to transfer different
messages.
The server and the client are running on the same machine.

Hello,
I would like to be able to poll to throw an event when the Receive buffer
for a UDP client is almost full. Basically, given a Socket object what is the
best way to 1.) Check the current max buffer size and 2.) Check how much data
is now in that buffer. Or, how can I set an event or poll a method that will
tell me when a buffer is full and droping packets?
Thanks,

Thanks for reading this, suggestions appreciated.
I keep getting an error at Sck.ReceiveMessageFrom.
I'm trying to not use the udpclient.
I'm mostly concerned with this part of the error:
or the buffer used to receive a datagram into was smaller than the datagram
itself.
I'm receiving this into?: Dim InBuf As Byte() = {}
What else can I receive it into?

Express C v9.1
I'm having a hell of a job trying to reduce the highwater mark for
various tablespaces in Express C. DB2MART advises to reorg several
tables with LONGLOBDATA and to disconnect, reconnect between each step,
but the tablespace snapshot is still showing a highwater mark as
follows.
Total number of pages = 2560000
Number of usable pages = 2559960

I have a class that creates an instance of the seril Port.
Every thing works fine except whenever I receive data I cannot display the
recieved data. I get no errors but the recived data seems to just go no
where.
I can see the recived data in my serial receive function but when I either
raise an event
with it or try to display it in a text box nothing happens. I do use
beginInvoke on the text box.
If I trace the code through it all...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
