c# - KeyCode and keyboard layout and language -

-

I have to include asterisks as an acceptable entry on the text box.

How can I test this key under keyboarding incident regardless of keyboard layout and language?

With the Portuguese QWERTY layout, ignoring this numeric keypad, this key can be tested through the key. Keys.Oemplus . But this will not be the case for other layouts or languages ​​

You are using the wrong event, you Keypad should be used. That fire when the user presses the actual typing key KeyDown is useless here, according to the keyboard layout the virtual key is translated into a typing key. It is difficult to guess that unless you translate keystrokes yourself, it may be difficult.

Some code: 

  Private zero text box1_keyPress (Object Sender, KeyPressEventArgs E) {string allowed = "0123456789 * \ b"; If allowed (Index (E.Keker) <0) e.Handled = true; }

The user is required to \ b to allow backspace.

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
