DataGrid reference is NULL after event was dispatched -

-

I'm a total flex novice and I struggle with the event model. I have the following scenario:

  • DataProvider is set to ArrayCollection
  • The data grid is a simple two-to-do list, checks in the first column as check junk
  • Other columns are plain strings

What I need to achieve is that after creating or starting a data grid, I have the color of the item renderers The style must be conditionally updated. The situation says, if the value of the property (stored in the data provider) is correct, then set the color of the text to gray.

The problem is that the item renders are initiated before the data grid is created, so the data grid reference that I can get in the item renderer is null. That's why I informed that the item renderer after data grid has been completed. The question is how to use the Flex Event Model.

It seems that the event items sent by the data grid were not heard by the renderer Please take a look at my code: 

    m; DataGrade column datafilled = "done" header text = "!" & Gt; & lt; mx: itemRenderer & gt; & lt; mx: component & gt; & lt; c: change status checkbox = "this.onChange (event) ; />

When I start my application and the data grid is created then the 'Update' event is triggered. However the update gate instance (DG) is used in the update styling function in the CustomLabel component. Why is it null now? As you can see in the init () method, the DG variable is not zero (the warning item goes for each example of the renderer)

Can you help me? Many thanks guys.

If you hear the dataChange event, it can trigger Handler

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
