c# - How to make ContentControl listen to non-routed event inside its ContentTemplate -

-

I have some reusable content controls, which work in the second view as a pseudo-modal popup. It is always there and only its visibility is visible or disappears. Within ContentControl, there will be a custom content template, which is bound to some view modal and represents the content of "modal popups". 

  & lt; Dialog: ModalDios DialogHost = "{Binding ElementName = Layout, Mode = One Time}" Content = "{Binding ViewModel.CurrentAditIT}" EyesShown = "{Binding ViewModel.IsInEdit}" & gt; & Lt; Dialog: ModalDialog.ContentTemplate & gt; & Lt; DataTemplate & gt; & Lt; Item Editor: Magnifier View / & gt; & Lt; / DataTemplate & gt; & Lt; / Dialogues: ModalDialog.ContentTemplate & gt; & Lt; / Dialogues: ModalDialog & gt;

Now I want to reach the following: The root of ContentTemplate (here: item editor view) should apply the following interface. 

  Public Interface ICLOS menu {event eventhandler & lt; EventArgs & gt; CloseMe; }

Whenever CloseMe-Event is removed, the surrounding modal dialog should be set to "hidden" by setting its visibility property hidden.

The scene within the popup (ItemEditorView here) should not be taken into account, whether it is shown in modaliodology or in some other context, i.e. should also know that such a class is not present. It does not involve walking through a logical or visual tree, it will only fire CloseMe-Event, when the cancellation / save-button will be pressed.

In addition, the mechanism should not be implemented / configured in the immediate form of modal dealog, the view should be as dumb as possible. .

Instead, "external" modalodyogic should be activated and listen to closeMe-event. How can I clean it, without implementing MVVM-compliant ways and unnecessary dependencies? Is there an event, after the start of a content template, STT Afterwards, modalodyoga can be evaluated, if its root extends to ICLOSME?

how to iCilaz mee Is that you can set the trigger against XAML?

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.

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
