I am new to programming. I know how to create simple windows app using VB and Sql Server/AccessDB. My question is this: Can my windows app be ran on a LAN or do I have to create a special multi-user app for a LAN? If the answer is yes, can someone please guide me on how to create a LAN/Multi-user app.

View 4 RepliesI am designing a fairly small application to manage a waiting area for a clinical department. There will be a receptionist who books appointments and updates exisiting appointments to say that a patient has "Arrived". In seperate rooms will be nurses who call patients who have "Arrived" and update the appointment as "In Session" and finally as "Discharged". The appointments are viewed in a flexgrid with nurses across the top and time down the left, patient names are displayed at the relevant times and the cells are shaded a colour to represent the current appointment status ("Booked", "Arrived", "In Session" and "Discharged").
I am using SQL Server as the back-end and Visual Basic 6 (I know) as my front-end.I have been told that there will be 2 or 3 nurses plus the receptionist logged in to the system but I would like to cater for growth.My question is what is the best mechanism to use in order to reflect the status change made by one user on the screens of the other users currently logged in?
I have been thinking about using a timer to refresh the data at a set interval but I do not want to keep hitting the server excessively (although what is considered excessive? we would be talking about a call for data every 60 secs per user). Plus the server could be serving data for many other applications so this is another consideration.Alternatively I have been thinking about sending some kind of message via Winsock to the other users notifying them of data changes as they happen. I don't have a lot of experience with this and am concerned about clients not receiving messages and users seeing old data. It also seems strange to me that once the days appointments have been retrieved from the database that "in theory" a client could go the whole day without having to query the database again to pick up changes - kind of scary.Some information on the data:We would probably be looking at around 100 appointments per day We capture patient name, date of birth, date and time of appointment and appointment status.What is the standard approach / best practice for this kind of scenario?

View 3 RepliesI have finished coding a VB.Net application that has connection to SQL Express 2008 database. My question is, what steps do I have to take to make this a multi user application.
FYI:There are 3 tables in the database of which two tables contain data to be viewed by the user and one table is to insert records by the user. The former two tables will be edited by the administrator only. So there is no issue of concurrency. But the one table that is used to insert records by all users has to be dealt with.

View 4 RepliesI have been trying for years making a network app.I need linked to a video or something, mainly on msdn or some microsoft site, because youtube created videos for coding aren't all that helpful as most of the microsoft made videos.
I need not linked to things like multi-user tcp chat application, as i have looked at these, and even found no code solution, but the no code doesn't allow too much customization and hard to deal with data received to make your own commands send and receive and have events for them.
The multi-user tcp chat application, it doesn't explain anything, just gives you the code for you to look at, and well, it's hard to understand.

Someone gave me a link to a Multi-User TCP Chat application once, but, there is a flaw in it, where it wont do special characters, such as Alt+1 will become a different character to the server than the one that was sent. Even I tried to see if the output was usable but it sees it as multiple chars, when it is only 1, and I can't find a link between what it sends and what the character is, so I can't just tell it based on whats sent what the char is, because I see no relation, I would have to type it out for each and every special character.

I have developed an application using vb.net. This application will run on approximately 15 machines at the main office and also roughly 10 machines spread over 3 different locations. I am using SQL Server Express edition in the backend. I deployed the application on the network using caspol but it is extremely slow. The Company Manager's perception is that because a script will invariably have to be deployed on each client machine to configure CASPOL, that the solution is not viable.
