I've had to separate my application into 2 apps. I need to second app to poll
the message queue for certain messages from the main app. Does someone have
some code on how to do this? I have the first app sending the messages, but
only have the second app able to respond once. The second app is started from
the first app as an independent process.
Thanks,
Susan

I have a couple of questions that hopefully someone could clarify for me. I
have an app that uses the threading.timer to constantly poll a scanner to
scan in documents. I understand that Async delegates can also be used for
polling purposes. Would it be more efficient to use async delegates in this
case? Are their any examples on how to use this under vb.net forms?
Thanks,
Jonathan

Is anyone aware of any freely available software written in a .Net
language for adding polling features to an existing website?
I'm looking for just a polling component and not interested in
installing something like DotNetNuke just to get polling.
Thanks

Hi guys, I have read several discussions on this group (and others)
that talk about polling a server using ajax transactions and if it is
possible to push to the client. The general consensus seems to be "no,
there is no way to push to client using ajax, you have to poll."
Knowing this, I assumed meebo.com and gmail talk are using the same
technique for their ajax chatting apps. However, when I use Fiddler to
sniff their http requests, I...

Hi everyone,
I would like to be able to send updates to my web page from the server. If I understood correctly, this is not possible to achieve in a web environment, unless some sort of polling mechanism is used. I read a few articles and some of them suggest using some Javascript, while other suggest using Web Services. Some ways to achieve some kind of polling mechanism is on this document:...

Hello all,
I have a little application that needs to poll a device (CAN
communications) every 10 to 15 ms otherwise the hardware buffer might
overflow when there are message burst on the bus. I would implement an
interrupt driven model, but the external device (which is connected
via USB) does not support interrupts therefore the device needs to be
polled at a specific interval. So my question is how can I implement a
"deterministic"...

Hi,
I've got two applications. The job of the second application is to make
sure that the first application is running; if it's not, it relaunches it.
Is there a good code snippet that somebody can point me to that would
accomplish this?
Regards,
Scott

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
