c# - A method that executes any time a class property is accessed (get or set)? -

-

C # - .NET 3.5

I have a family of classes that inherited from the same base class Is of I need a method in the base class (received or set) to use any asset in a tool category at any time. However, I do not want to call the base class to write code in each and every property ... instead, I hope that there is a narrative way to "sync" this activity in the base class.

Adding some spices of necessity, I need to determine the property that the access was made, the value of the property and the name of its kind.

I imagine the imagery solution would be a clever combination of generic, and the reflection I can imagine to make some sort of array of representative behaviors on the runtime, but by re-running the member InfoTo in the producer, Would, will affect its performance. Again, I hope there is a more direct "narrative" way to do this.

Any thoughts are most appreciated!

You can not do it automatically, but you can get free for 95% free of charge. See this is the classic case for Aspect-oriented programming , which has class. Here's how you can solve your problem: 

  [Serializable] Public class FieldLogger: OnFieldAccessAspect {public override zero OnGetValue (FieldAccessEventArgs EventArgs) {Console.WriteLine (eventArgs.InstanceTag); Console.light line ("found value!"); Base.OnGetValue (EventArgs); } Public Override Zero OnSetValue (FieldAccessEventArgs eventArgs) {int i = (int?) EventArgs.InstanceTag ?? 0; EventArgs.InstanceTag = i + 1; Console.light line ("set value!"); Base.OnSetValue (EventArgs); } Public override InstanceTagRequest GetInstanceTagRequest () {return New InstanceTagRequest ("logger", new GUID ("4f8a4963-82bf-4d32-8775-42cc3cd119bd"), false); }}

Now, anything that meets FieldLogger will get the same behavior Prestige!

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes. All st...

php - Multiple Select with Explode: only returns the word "Array" -

By using Wordpress I have created a multiple selection box so that users can select categories to exclude. When the page is initially loaded, I see my predefined default option. However, when I select a new value and I save ... I only see the word "Array" and have not chosen anything else? & lt; Class = "amultiple" id = "& lt; php echo $ value ['id'] ;? gt;" name = "& gt; php echo $ value ['id'] ;; gt; []" Multiple = "multiple" size = "8" & gt; & Lt ;?

jquery - SimpleModal Confirm fails to submit form -

-
I am trying to confirm jQuery to show yes / no confirmation when I submit a form. I had modified (in the last list) to capture and block form submissions. However, it only works with jQuery 1.2.6, a recent upgrade stops 1.3.2, if yes is clicked, then by submitting the form. But I can not understand what is wrong / inconsistent in my code now. Demo (which works in both versions of a simple window.href implementation). $ (document) .ready (function () {$ ('input.delete'). Click (function (e) {e.preventDefault (); var target = $ (e .target); Confirm ("Really delete this event?", Function () {target.click ()});});}); How about something like this? The idea of ​​catching clicks (and fire!) On the submitted event is not click event. $ (document) .ready (function () {$ ('# myForm'). Submit (function () {var f = this; Confirm (" Remove? ", Function () {$ (f). Submit ();}) Return; Return the initial session;}}}}; Hope That this is som...
