iphone - converting NSString to precise number for performSelector: afterDelay: -

-

I am communicating with a webservice to get the numeric value in my function as an NSString This number tells me the exact time to wait until taking another action, and it is important that this is accurate.

As an example, if the string is "89283", that means that I should wait 89.283 seconds. So I would like to know the best way in Objective-C so that the iPhone can convert this string to an exact value that I can pass to display: later: function. Here's my sample code, but I'm making an accurate estimate of it. 

  NSString * myDelayString = @ "89283"; Int myDelay = [myDelayString intValue] / 1000; [Selector to self: Object with @centor (myfunction): after zero: my dell];

I think my della value should actually be an NSTimeInterval, but I'm not sure how to make a string with me thank you in advanced.

There is a code with the change to allow double precision. 

  NSString * myDelayString = @ "89283"; NSTimeInterval myDelay = [myDelayString doubleValue] / 1000; [Selector to self: Object with @centor (myfunction): after zero: my dell];

Use double values ​​to get the string as double so that you can avoid integer division. The type of NSTimeInterval is defined as double on the iPhone, so you can add double results in it and then you can give it later: Part of the selector.

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
