Developing A Simple Online DBMS To Browse Database Online?
Dec 6, 2010
I am developing a simple online DBMS to browse my database online.... the main concern for me is to clear everything from the PC when the user disconnect so no body can go and click (Back) on the browser and see the pages if the user forgot to close it.. what I have done so far is :
[Code]....
I am sure this is not enough.. am I right? so what else I should include there?
I am developing a web application which will deal with online examination. The requirement is:
There can be n-number of sections in an exam and admin users should be able to create questions/answers and add to an exam. The questions should be displayed for a certain amount of time in the browser with meclock and it should move to next question automatically. User should not be allowed to open any other instance of the browser or login from another IP if the exam is in progress.
I am seeking community vote of how would someone design the application to meet all these criterias? What patterns should be used? What components to reduce the development time etc..My technology stack is C#, ASP.NET MVC or ASP.NET with SQL Server.
I want to create a Online Exam site in ASP.NET .In that i want to display Test based on the Date and time and the user can take the test at the time set my the Teacher.
For Example:
Teacher want to take C Test for the Mid Semester Test and the test is schedule on 1 May 2010,then the test should appear on the test page on the 1st may only and the user should be able to take the test on the set time.
The problem is that if i use System time then user can change the system time and can take the test schedule in future.
So i want to know how can implement this thing.I have given many online test but dont know how they work out the time and date logic.
Im about to create a very simple online event reservation application and currently have 3 tables:
User PK_UserID UserName Event PK_EventID EventName EventDescription EventStartDate EventEndDate SeatsAvailable BookedEvents ID FK_UserID FK_EventID
Do you have any experience of how to handle SeatsAvailable? I mean if SeatsAvailable is set to 5 and there are 5 users online and want to book event. And some user has started to fill out the form then changed his mind. Then seats in database can just leak. I was thinking about sessions - like to limit every user to 5 minutes to complete the booking but i dont really know.
I have all my tables and queries in online DB ie., i have created all my tables and queries in online using third party site [URL] Now i want to make connect my application (which is in my system) with that database

connecting my database to the online server. My server is seekdotnet. But I had been receiving this error code Cannot open database "database.bak" requested by the login. The login failed. Login failed for user '219_nypmecom'.
I'm a little frustrated here. I have turned the default database offline then used windows explorer to copy the database to another location but when I tried to take the database online again this error came out:
Cannot open user default database. Login failed. Login failed for user 'Zephere-pcephere(JuLian Yong)'. (Microsoft SQL Server, Error: 4064) The cause is that the default database is set offline, How do I bring it back online agian?
I'm working on an application that is connected to the online MSSQL database and everything is working fine.The model I'm using is entity model.The problem is that I have to change the connection string from the online database to the local one,but I don't know how.Creating new model isn't an option.I tried changing the connection string in web.config,but errors are the only thing I get.
My website is working but when I host it up, the connection are all screw up. Is it because my connectionString are all linked via SqlDatasource and is for local files only? Whats the coding that I need to put in so that my site will connect to the database via accessing the web.config or server?

I'm looking for a simple way of developing "System Notification" in an ASP.NET website, which will consist of two parts: Part 1 - The administrator with go to a special page and enter 3 elements for the notification:
Notification Text (e.g. "System will be down for maintenance next Sunday 11/26/2010 from 1:00 AM to 1:30 AM Pacific Time) Starting date/time when the notification should be displayed (e.g. 11/23/2010 6:00 AM) Ending date/time when the notification should be displayed (e.g. 11/26/2010 1:30 AM) Part 2 - Once the user logs into the website within the above timeframe, the system notification message will appear on the home page. What would be a good architectural location for this?
- A table? - An html page? - Part of web.config file? - A new notification.config file? - Where else?

I have a page in my application which always shows updated list of online users. Now, to keep the list-which is stored in application object- updated, i do the below steps
add user to list when login remove user on log off Then to handle browser close/navigate away situations, I have a timestamp along with the username in the collectionAn ajax call every 90 seconds updates the timestamp.
The problem:
I need something to clean this list every 120 seconds to remove entries with old timestamps.
How do I do this within my web application? ie Call a function every 2 mins.
PS: I thought of calling a webservice every 2 mins using a scheduler , but the hosting environment do not allow any scheduling.
