    <p>Good afternoon everyone,</p> <p>I am trying to use the example "Aspect Oriented Programming Using C# and PostSharp" by Reza Ahmadi <a href="http://www.codeproject.com/Articles/337564/Aspect-Oriented-Programming-Using-Csharp-and-PostS" rel="nofollow">http://www.codeproject.com/Articles/337564/Aspect-Oriented-Programming-Using-Csharp-and-PostS</a> and dnrTV <a href="http://dnrtv.com/dnrtvplayer/player.aspx?ShowNum=0190" rel="nofollow">http://dnrtv.com/dnrtvplayer/player.aspx?ShowNum=0190</a> for the exception handling. Everything works great if the "OnExceptionAspect" is in the same project/assembly, however the event does not work if it I move the class to it own dll.</p> <pre><code>[assembly: ExceptionAspect (AttributePriority = 1)] [assembly: ExceptionAspect(AttributePriority = 2, AttributeExclude = true, AttributeTargetTypes = "HpsErp.Common.AspectObject.*")] namespace AspectObject [Serializable] public class ExceptionAspect : OnExceptionAspect { public override void OnException(MethodExecutionArgs args) { Trace.TraceError("{0} in {1}.{2}", args.Exception.GetType().Name, args.Method.DeclaringType.FullName, args.Method.Name); if (args.Instance != null) { Trace.TraceInformation("this={0}", args.Instance); } foreach (ParameterInfo parameter in args.Method.GetParameters()) { Trace.TraceInformation("{0}={1}", parameter.Name, args.Arguments[parameter.Position] ?? "null"); } } </code></pre> <p>I also created a class in the external dll for "Timing" and it works great if I add a custom attribute to the class.</p> <pre><code>namespace AspectObject [Serializable] [MulticastAttributeUsage(MulticastTargets.Method)] public class TimingAspect : OnMethodBoundaryAspect { [NonSerialized] Stopwatch _StopWatch; public override void OnEntry(MethodExecutionArgs args) { _StopWatch = Stopwatch.StartNew(); base.OnEntry(args); } public override void OnExit(MethodExecutionArgs args) { Console.WriteLine(string.Format("[{0}] took {1}ms to execute", new StackTrace().GetFrame(1).GetMethod().Name, _StopWatch.ElapsedMilliseconds)); base.OnExit(args); } Using AspectObject; namespace MyApp { public class Car { [TimingAspect] private void Drive() { //... } } } </code></pre> <p>In the end, I am hoping to have this is multi dlls so that I can reuse it ie: wcf.</p> <p>Thanks for any and all help...</p> <p>James</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
