As suggested the OUTPUT is a waste of time (I'm not aware that you cannot send a value in via n output parameter, I never use them), you never consume them just pass information in.

The error indicates that you are NOT passing in a BookID, so remove the OUTPUT and debug to parameter add value and make sure it has a value.

Have a read of this http://stackoverflow.com/questions/1550293/stopping-textbox-flicker-during-update[^]

Also I would make sure that you have double buffering set on your form too.

Well, it happened when you overwrite text into your textbox control.
Please, consider how to append text not overwrite.

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.

Thanks Max
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.

Connections via Web sockets would offer a more real time environment,

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.

Exploring the Unexplored.

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 | :|
