c# - Validating User Input and Type -

-

I have designed an input validation loop in C #, and I want to be able to check it for the correct input format. I'm not sure, but I think that my designed loop is not checking the type of input, just the character that has been entered. I know that I can use an effort-block, but should you not use exceptions only for extraordinary situations? This is not an extraordinary situation, because I hope the user will enter the wrong value.

Question:

Is there a way to give it a new look, so that it is a valid input type Also checks?

Code: 

  do {console.write ("Do you want to enter another complex number?: (Y or N) "); Feedback = char.Parse (Console.ReadLine ()); Reaction = char.ToUpper (feedback); If (feedback! = 'Y' and feedback! = 'N') console.light line ("You must answer Y or N!"); } While (feedback! = 'Y' and feedback! = 'N');

Good:

reads the next line Characters from standard input stream

Then your data will be of type.

You can only do another check to check that the return length is 1, so you know that you have the correct format input. You can actually enter char.Parse < / Code> is not required because the elements of the string are of char .

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
