asp.net - Problems with Response.TransmitFile, Response.End and IE -

-

I am developing an ASP.NET app that responds to the user at one point. Transmissions sends using the file.

This works fine on my god machine, and even when I put it on the test server, still works on two of them; Although one of the servers (W2K3) only works on Firefox, when I try IE7, I get an error like "Internet Explorer can not open the file (server name) on sendfile.aspx."

I have created a small inline ASPX page to do the problem again, here it is: 

  & lt;% @ page language = "c #"% & Gt; & Lt; Html & gt; & Lt; Top & gt; & Lt; Script language = "cs" run = "server" & gt; Zero Page_load (Object Sender, System.EventArgs E) {string filePath = @ "C: \ temp \ export.zip"; Response.ClearHeaders (); Response.ContentType = "app / zip"; Response.Clear (); Response.AppendHeader ("content-effect", "attachment; file name = export.zip"); Response.TransmitFile (filepath); Rispans.and (); } & Lt; / Script & gt; & Lt; / Head & gt; & Lt; / Html & gt;

I have tried different things and I have seen that if I response End line (but AFAIK should be there, at least according to every sample code I search around the web)

Another issue I have seen which may be related Or I can not believe that if I & lt; Html>, & lt; Head and gt; and its closing tag.

I am scratching my head on this for some time, does anyone know how to do it?

Do not use feedback. the ending ();

Try 

  Response.TransmitFile (filepath); Rispans.and ();

In fact, after .NET 2.0, you get the 

  response. Transmission file (file path) should be used; Context.HttpApplication.CompleteRequest ();

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. All st...

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...
