actionscript 3 - Resizable Button with background in flash CS4 -

-

I want to create a button that changes dynamically with content. To achieve this, I made a movie clip in the library and included four layers in it - text, bg, shadow and border.

I think if I autosize the textfile, only the size of the text changes and the other things remain as if it is. If I calculate the need of width using the xxxLineMetrics function and it is applied to the button, the background resizes properly, but the text field is also spread with them and looks ugly.

I want the background (textfield's brother)

I hope that people will meet me who I want ... any help appreciated ...

Thanks,

You should apply the calculated width only to BG Movie Clip and for the full movie clip No. Because it will also change the width of the textfield.

Then try to do something like this: 

  txt.autoSize = TextFieldAutoSize.LEFT; Txt.text = "label"; Btn.bg.width = txt.width;

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
