I was searching server software to build a Multiplayer Online Game. All of the servers I found up to now use Java in the server side (ie smartfoxserver)
Today I found this one, Photon, that seems interesting because it uses .NET, you can see it here:

I need a reliable way of checking if a user is logged into a web based game. This is the scenario:
I have a game on the front end built in Flash with Actionscript 3, that calls a web Service in .NET. So in some way I'd like to create a reliable way of getting a list of users that are logged into the game. I would need to create a Timer in Actionscript that calls a method in the Web Service every certain amount of time, but I'm not sure which is the best way to do it on the server side.
I remember in the old days with classic asp I'd use global.asa and it was not reliable at all. Also, checking a database with a boolean, would always depend on the user clicking on "logout". So i guess there needs to be some kind of asyncronous coding in there somehow.
I am going to start a new online trading simulation game.
Server Page:
A game will be loaded with an xml which contains the instruments for this game and each instrument initial and changing factor price(which determines the price for the next interval ex: 1 min).
User Page:
After the game is loaded successfully, Users can launch a page where they can buy/sell instruments. During this buy/selling process, the profit/loss should be shown to user in real time. A dropdown will be populated with the instruments, when selected, should show a real time graph of the price.
Design:
I want to use ASP.NET and silverlight to develop this application where an ajax request will be sent in configurable time to the server to get the latest details about the instruments. Then based on the response, the client browser will be updated with the latest prices. The instrument graph also will be updated in the same way. So, I would like to know whether this is a right way of building this applicaiton.
my question is this, how can i simulate a text base basketball game in a web application.
The game logic class is ready and in use in my WPF application, however I want to transfer it to a web base application. But I have no idea how to keep the game thread a live + updating the UI every second.(only text update are required).
I want to know that how many sites like jqueryui, etc. build online zip packages for download. And how it can be done in asp.net ?
View 2 RepliesI need to build a page to test online video speed.
video will be uploaded in my webserver and there is no flash play in the server. I need to have two players. one is window media player, second is a flashplayer (prefer using google player)
Page layout:
Windows media player
report of speed testing
Flash player
report of speed testing
report requirement
1.length of video
2. total time that spend to load this video (dynamic is better)
3. average download and upload speed during playing the video
I'm a student doing final year of my Computer Science and Engineering. For my final year project i've choosen to do an online word processor such as google docs,zoho etc.I want to implement this project in .net. This will be a ajax oriented project and i'm well prepared with the web related part of it with ASP.net and C#.net at the server end and HTML,Javascript at the front end. But the point where i'm struck up is:
-> How can i create, edit and add MS Word features to a .doc file using VB.net or C#.net??
-> .net Library classes that will be helpful for me to create word related components as .doc files i.e how to create word using .net?
-> How can i convert a .doc file to HTML file to display it on a web browser?
-> In brief tell me how to create a word processor so that i'll be able to create it online.
I have a web application running on ASP.NET 3.5 which basically stores, retrieves, and allows users to manipulate data from a SQL Server 2005 database. One of the features allows users to search through the records in the database. When the system was first launched last year, there were no records, so searches were lightning fast. However, over the past year, about 100,000 records have been entered, so most searches now take over 15 seconds to perform. I'd like to speed up searches, but there are problems with both of the conventional approaches I can think of:
Caching - The database does all the heavy lifting in this application - the ASP.NET web application is little more than a UI that passes user input to the correct stored procedure, and displays the returned output. The stored procedures are responsible for interpreting user input, applying the business rules, and transforming the underlying tables and views into a context-sensitive result set which the application just displays as is. Unless if there's a way to apply a stored procedure to a C# object/collection (the cached records), and get another C# object/collection back, effectively bypassing the database, I don't think this will work.Stored procedure optimization - There's some optimization potential here, but even a simple SELECT * FROM TheView statement on the underlying view currently takes 11 seconds according to SSMS, and I expect that the amount of time taken will continue to increase as more records are entered.Are there are techniques out there that I'm not aware of, which could be used to bring searching down to a reasonable amount of time (5 seconds or less per search)?
We have a database with a lot of information about Persons. I won't post the entire database structure because it is too big, but it looks something like this:
Person
ID
Name
Street
City
State
Country
Language
LangCode
Language
Interest
ID
LastChangedBy
LastChangedOn
LocalizedInterest
InterestID
LangCode
Description
PersonInterest
PersonID
InterestID
Now, this is just a small example. In our database, we have about 8-9 localized tables (like Interest) a Person can be linked to. A Person can have multiple Interests, a Person can have multiple Jobs, a Person can have multiple Educations, a Person can have multiple Experiences, I have to build a search function. Let's say you enter "tom" as the search term. This should give a list of all Persons with "tom" in their Name, Street, City, State, Country, in one of their Interests, in one of their Jobs, in one of their Educations, in one of their Experiences or in one of the other linked tables.
If you enter multiple words to search for (eg. "tom php"), it should give a list of all Persons with "tom" in their Name, Street, City, State, Country, in one of their Interests, in one of their Jobs, in one of their Educations, in one of their Experiences or in one of the other linked tables AND "php" in their Name, Street, City, State, Country, in one of their Interests, in one of their Jobs, in one of their Educations, in one of their Experiences or in one of the other linked tables. At the moment there are about 4,500 records in the Person table and if I do an outer join of Person with all the tables I have to search, there are about 1,300,000 records and 40-50 fields to search in.
How should I approach this problem so that performance will be acceptable? The client expects "something like Google" in terms of speed and ease of use. We're using MS SQL Server 2000 and ASP.NET 2.0. The search functionality has to be added to an existing application and changing the technology or database structure is not an option.
suppose i have column values:
3
6
3,6
36
363
i want to display column which contain "6" means
6 and 3,6 not 36 and 363
so i am using full text search:
use PMS
go
EXEC sp_fulltext_database 'enable'
go
CREATE FULLTEXT CATALOG pmscatalog
go
CREATE FULLTEXT INDEX ON PMS.dbo.emp_project
(
empid
Language 0X0
)
KEY INDEX PK_emp_project ON pmscatalog
WITH CHANGE_TRACKING AUTO
SELECT empid
FROM emp_project
WHERE CONTAINS(empid, '"6"')
but it is not returning anything...
I want to query an SQL table using some Web controls to provide the parameters for filtering the records in the table. Results are displayed in a GridView.
I have a TextBox with an ID of "keyword" where the user may enter one or more keywords. I'd like to search 2 columns for instances of these keywords.
I also have a DropDownList named "category" that lists categories contained in a "category" column of the table.
I have a dataset with a TableAdapter for the table I want to search. Got it working fine with the DropDown List but not sure how to proceed with the TextBox and keywords.
What SQL query should I use? The user may not enter anything into the textbox, they may enter one word, or multiple words.
This is where I am now:
SELECT * FROM tablename WHERE category = @category AND ??
OLE DB provider "SQLNCLI" for linked server "xx.xxx.xxx.xxx" returned message "The partner transaction manager has disabled its support for remote/network transactions.".

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.

View 1 RepliesI was wondering, though I have got quite a few articles in this regard and all of them are for previous versions of XNA or not what I need, is it possible to embed an xna game in a asp.net website???
Means like there are several websites (game portals) having several games of may b flash or java. But is it possible to embed your xna game in a web site, and play it on web. May be using Silverlight so that User playing online do not have to updates its DirectX drivers or stuff.I am a beginner in Game Development.
Is it possible to host a game say counterstrike on ftp. eg. [URL]
This provides a game control panel to handle server from website. How game gets started on hosting server. Do we needs to install game on hosting server though commands given in its API. or is it there some other procedure to host game on hosting server
EDIT
Try referring to this link which show requirement of the control panel. I want to develop a same kind of thing with only starting and stopping server
I apologizes for not being able to explain my question clearly as even I dont know how to make my question clear as I used to play this game host server on my system. But want to host server on web hosting server.
My question is the same as my subject: how to put asp.net website with sql server database online.
I've never done this on my own before so can anyone explain it?
Where can i put it online and so on..

I'm creating an online Clock-in/out tool. An employee may have to leave work for a bit and return at a later time in the same day. This would cause multiple entries for the same date. I need to be able to show the daily total for each date. I have not been able to get SQL to total up the times and only display the date once. The image below shows some data in my table and the outcome that I am trying to achieve. The first table has 2 rows highlighted. They have the same date. The second table shows how I would like it to add the two rows and display them as one.

I am developing a small browser based game in asp.net. Think of a game room which has a capaticy of 22 players and players join the room by clicking a button. ( I am saving the number of players in the room in database) I need to call a method when the number of players in the room is 22. The problem is I don't know how to control the number of players in the room. I mean I think like there need to be a bacground code which has to run all the time at the server and that code controls the number and call the function.
