Hi I am planing to develop desktop application game for multiple players online and as idea to archive this i plan to use webservices to communicate players between them.

Does webservices are good for manage multiple players or is any better way to do this?

Thanks and regards.

Web services will be too slow for real-time video games, but could be OK for something like a chess or checkers game.

The game will have max 4 palyers so webservices are good choice to use for communicating between players?

The game will have very simple graphic interface so all what the game will process that are few data rows and keeping updated some statuses which are stored in SQL Tables.

Real time no, slow (the kind of thing that you get as browser games) yes as it means you don't need any custom central server, just a HTTP server set up with the service endpoint.

If you break out that code and look at what it generates, it's fairly obvious what the problem is likely to be:
Assembly a = System.Reflection.Assembly.GetExecutingAssembly();
AssemblyName nm = a.GetName();
string s = nm.CodeBase;
string p = System.IO.Path.GetDirectoryName(s);
AssemblyName.CodeBase returns a value of the form:

file:///D:/Folder/Application.EXE

Which GetDirectoryName truncates to:

file:///D:/Folder

The chances are that the SqlCeConnection class does not like that. Try:

System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location)

instead.

Hi All,

I want to have a single project which holds the DataSchema files like EDMX files.

The problem which i am facing is if i create a reference of the PRJDataSchema Project project and try to query the EmployeeEntity i get a "type used in a using statment must be implicitly convertible to 'System.IDisposable'"

How can i resolve this problem.

If i create a class file in PRJDataSchema , like i have created a Test.cs file then i get no problem.

I want to fix the problem in screenshot 1.

any help would be appreciated.

Issue solved by manually adding reference of "System.Data.Entity" to PRJDataAccess and then add it as using System.Data.Entity to the EmployeeDAL.cs.

Stupid me. Hmmm | :|

Hi,

Imam using this to close the connection but I feel after many entries that the system will be slow and it will take a very long to run the process.. so is this enough:

if (sql_reader != null) sql_reader.Close();
if (sql_connection != null) { if (sql_connection.State == ConnectionState.Open) sql_connection.Close(); }

That'll close the reader and the connection, but will not dispose of it - leaving that to the GC. Ideally, they'd be wrapped in a using-block.
