What's a page? If you want a form, please do. Images (whatever format) are linked as a resource. In ASP.NET, you'd simply link to the picture on the server.

These are very basic questions; you'll find answers to more of similar questions you'll have in a good book on the topic. I suggest you start in the nearest library, or the beginner portal[^].

Hi lads and lasses, I have just started looking into communication between services and GUI apps. I decided to use Named Pipes but upon reading a lot of documentation and web examples etc etc it seems that after every message is sent and received you have to setup another server/client to get the next message???
Is this the case? What I wanted was a TCP like connection (yes I know that is an option) where I can set a server listening then connect a client and then through the lifetime of the app just pass messages between the two apps (service and GUI).
Is this possible?
thanks

You're not creating a new listener for each and every message.
You would normally create a listener that waits for connections. Once that connection request arrives, you create a pipe server for that client. That way, you can have multiple clients connected to the service at the same time and no interfere with each other.
Now, if you just want the local machine applications to talk to the server, then the service only has to listen for one connection. It doesn't have to spawn a new server object for each incomming connection.

Thanks for the reply, but the problem is all the examples do spawn a new server object or shut down the server after the first message arrives.
thanks

You're going to have to point these out because that's not the norm.

Bad example. That one does do what you siad, but it was written as an ad-hoc example to demonstrate the new Pipe classes. It's NOT meant as a tutorial on how to use the classes in production.
That example actually comes straight from the MSDN documentation, which uses very simplistic examples on using specific classes. That example, and many many more in MSDN, is by no means the definitive source on how to properly implement a server using pipes.
An implementation that would look closer to a real-world example is this[^].

Hi to all,
How can i communicate between Siemens PLC and Visual C# via USB PPI cable as serial communication? When i plug it to my pc so it is identified as a HID device. i want it as com port.(serial pot). how can i achieve this? must i attach any kind of dll to my project? Anyone can help me?

The driver for the device has to expose the device as a COM port. If it doesn't, you're going to have to go to the manufacturer of the device and either get an updated driver that does this or get a SDK for the device that allows some other method of communication.

if you are looking at doing this automatically I would have a look at the leave event of the textboxes.
Textbox.Leave[^] event further reading.
you will need to write on of these for both textboxes, and on leave I would check to make sure that the value is a number before performing the addition of the 2 values.

Please i want complete code as per my question
Sorry I have told you in a descriptive way how to do it, in the link I also gave you it had an example of how to use the event, but I am not going to write it for you! I will however help you debug the solution if you have trouble.

Use the MonthCalendar control. Subscribe to the DateChanged event. When the date is changed, read the content from whatever data storage method you decide to use, be it XML or whatever.

During my implementation for a client/server application I encountered the follwing problem:
Let's say we have a client application C which is the remoting client and that connect to a Server application S which is the remoting server.
C has two NICs which are both activated.
The problem is when both cards are activated, the client application C is having a hard time establishing a connection with the remoting server S. It seems that the client cannot detect what card to use. Whenever we disable one card, Everything works fine.
Some sites adviced to configure the "bind to" attribute but it does not work.
Note that when running both application on the same machine, no problem occurs. This occurs only when the client and server application are run in different machines.
Does anyone know how to correct this?
Thanks in advance.

I'm guessing it works on local machine, because it goes direct on looback (127.0.0.1).
I think what you need (not sure) is to add a route. This way you'll be telling whenever I'm connecting to S, use specific gateway.
google "adding route multiple nic"[^]
hope it helps

Thank you for your feedback. This solution may work but it will not be the best approach. The thing is that we cannot oblige the end users to configure that since that it may affect other applications.
I think that this should be handled in the application level and so on it will be transparent to the user.
Any idea about how to make that configured in .Net Remoting?

Again, I'm not sure about all this:
- but I think this is a pure low level windows setting/config. Routes have to be configured/added like IP, gateway, mask, mac, etc of both network cards. I don't think this is a per-application domain (but don't hold my word to it).
- there probably is a way to add a route from your .net program, but it probably requires administrative privileges (instead of configuring it manually).
- I think "other applications" are already using a route that is configured right
btw Why are they using dual nic? I'm curious on what is the use case.

Thank you for the feedback
First, I have just fixed this by configuring with the machine name instead of the IP address. That is a kind of workaround about that
To answer your question, there is no use for dual nic actually. I was testing my application on a new machine and I got the error (since it does have 2 network cards) so I was figuring out if I could manage that

Can anyone suggest any good books or tutorials on WPF-MVVM please? I am looking for latest books or tutorials... not the old or outdated ones... Books or tutorials with hands-on or practical examples... Thanks.
