The application is missing the icon App.ico. You have probably hard coded the path to this icon, and the path in the new computer is different.

As well as Wayne's answer, you really need to check which forum you post your messages in. This is the C# forum, and people can be very unkind to VB.NET here.

I wanna to write Symbian App via C#.
what are preRequites and how can i do that.
Thanks!

Unless you have an old copy of DefForge's Crossfire available, you're out of luck. Having looked into this, as far as I can find there are no current facilities available to allow you to write C# code for Symbian.

You can use ITextSharp to convert a pdf file to an image.

I am trying to develop (on c#) a Point of Sale program(deployed on machine 1), with integrated kitchen display system(deployed on machine 2). I pretty much have an idea how to develop the individual programs, however, I haven't tried integrating thee machines (to function as one) before.
Here's a brief overview of the system im trying to do:
Machine 1 : Point of Sale
function - Enter customer orders(do basic POS functions), then PUSH the list of order from the POS to the kitchen display system.
Machine 2 : Kitchen Display System
function - Basically what it needs to do is to receive the list of orders pushed by the POS, then queues whenever several tickets were sent at the same time. The KDS bumps a ticket when the order was already prepared. The list queue then moves...and so on.
Machine 3 : Queue System
function - when the KDS (kitchen display system) bumps the ticket, the ticket number then displays on the screen. (e.g. serving: 21)
I'm suppose to implement this using one server running on windows XP or later, and three thin clients. Another option for me is to run this using terminal services(server 2003). Each thin client is equipped with a touch screen display.
I am hoping for your inputs. Thank you very much!!

What exactly is your question?

Hi Richard,
Im trying to figure out how am I suppose to implement this project using three different machines. (e.g. when pos pushes the order, the list will appear on the kds monitor) I've never tried integrating 2 or more computers to function as one before.
|
|
|
|
|
Your question is very broad. But one idea is that you can have the POS machine put the order into a database table, and then the KDS machines query the table to see what new orders there are.

...the impossible takes slightly longer.

I would prefer to have the data transferred realtime (upon input), rather than the KDS sending frequent queries to the database. Im thinking about socket programming(which I dont have any idea about). Is it applicable for my project?
|
|
|
|
|
Yes, it would be appropriate if you want to transmit the data in real time.
You'll need to look for a good winsock library that can take care of the communication for you if you don't know winsock programming. Search for "Winsock library".

Thank you Richard. I would have to research on winsock library. It'll be a kick start for me. thanks again! - Carlos

And what happens if you can't connect? You can't transmit the data then. Plus, does it really have to be real time? Would a one minute delay really cause that much of a problem?

hello Pete,
The program i'm trying to make is supposedly for a quick service restaurant. More like a fastfood (e.g. Mcdonalds). It would be much better if I can get the data passed on to the KDS terminal immediately after being entered on the POS. If the KDS terminal cannot connect to the server, the operation will halt.
|
|
|
|
|
Then have the KDS terminal poll at a faster interval (e.g. 5 seconds). The architecture you are proposing currently is far too fragile.
|
|
|
|
|
What you're proposing will not work. Sure, you can send the order, but what if the second machine is down or the network is down at the time?? Your design is not fault tolerant at all, not to mention unscalable.
Once the order is sent, your POS machine no longer has any record of it once the other machines come back up. So what happened to the order and how are you going to get it back??
The POS machine should put the order in a submitted orders table in a database. The RDS machine would then have to pickup the orders from that table WHEN IT CAN, not when the POS sends it.

Then the servers start manually carrying the tickets to the kitchen.

That is pretty long for a high volume restaurant. Assuming single floor layout a server can deliver it to the kitchen in less time than that.
