RemoteEventCounts in FbRemoteEvent

Rate this Message:
Hi Jiri, i have one question:
It seems like handling of RemoteEventCounts-Event of the FbRemoteEvent class occurs in other than calling thread. It means, accessing some outside objects inside FbRemoteEventEventHandler is not thread safe (and this fact is not obvious). Can you consider it as Feature Request - raising FbRemoteEventEventHandler event in calling thread context? I could try to make a patch on the Weekend (but i must look into the code first, to find out, if i can do it myself). |

Hi Jiri, so I managed it faster as supposed.
The original problem: Suppose we have following code in for instance Windows Forms window.
public Form1()
{
InitializeComponent();
FbConnection conn = new FbConnection("some connection");
conn.Open();
FbRemoteEvent remoteEvent = new FbRemoteEvent(conn);
remoteEvent.AddEvents(new[] {"TEST"});
remoteEvent.RemoteEventCounts += new FbRemoteEventEventHandler(remoteEvent_RemoteEventCounts);
remoteEvent.QueueEvents();
int id = Thread.CurrentThread.ManagedThreadId; //Here we'll have value for instance 10
}
void remoteEvent_RemoteEventCounts(object sender, FbRemoteEventEventArgs e)
{
//Here we are, when event fires
int id = Thread.CurrentThread.ManagedThreadId; //this value will be different from value obtained in Form1 constructor
bool v = this.InvokeRequired; //Expression is true, that means if somebody writes here something
//like this.textBox1.Text = e.Counts.ToString()
//there will be Exception about accessing UI from another Thread
}
My patch should address this issue so that objects of the spawning thread can be safely accessed from event handler. Could you test it and commit if you find it useful?
Regards, Pavel.FbRemoteEvent.patch |

I downloaded Provider 2.1, I found somes problems:
1. variable shouldDisposeSelectCommand in FbDataAdapter class not assign anywhere but it's used. 2. FBScript constructor with parameter filename, I think should has contructor with script input. I build a web service program, client program read file and send script to server, I use FBScript class to update into DB. 3. Function: RemoveComments(string source) of Fbscrip should change from private to public.

No, it's not EF related. You just have to use C#3.0 (to understand lambda) compiler on FW3.5 (to have extension methods for IEnumerable), which is current development platform. These extension methods are just syntax sugar, so it doesn't affect FW2.0 run. -- Jiri {x2} Cincura (CTO x2develop.com) http://blog.vyvojar.cz/jirka/ | http://www.ID3renamer.com ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Firebird-net-provider mailing list Firebird-net-provider@... https://lists.sourceforge.net/lists/listinfo/firebird-net-provider |

The source code for FbScript is available, if you need your own version, just use it. You can't make every method public just because someone, somewhere, might one day want it.
