Event Handlers

I'm moving from your retail version of about a year ago to the open source one.

One of the difficulties I'm coming across is with the lack of delegate event handlers.

this.Interpreter.PositionChanged += new GeoFramework.PositionEventHandler(this.Interpreter_PositionChanged);




Many Thanks


Edit: Clarification. PositionEventHandler used to exist in the older retail version I had. I just need some help being pointed in the right direction.

Second issue someone might be able to shine some light onto. For some reason I can't get the windows form designer to consider the controls safe unless I have the asmmeta file found with my retail version.


Also I'm using CF 2.0

.NET Framework 2.0 introduced the EventHandler<T> generic which we now use instead of making delegates for every event.  As a result, PositionEventHandler would become EventHandler<PositionEventArgs> and so on.  As for the wndows Forms designer, we've always struggled with obscure Windows Forms errors since the beginning.  Since the errors give you stack traces into Visual Studio's own code, these errors are nototiously difficult to debug.

Ah ok. Thanks for the reply.
