asp.net connection open and close -

-

Assume that I have an asp.net application that continues to release some pages that use the connection .... .

I have opened the connection in the class file in the constructer ......

and it accesses it using the object of the class .... When the database operation is needed .. .

The application is running fine initially ... but after some operation of the database in DataGrid (pre-sorting, paging, other) .... it gets slows down ... and then working After some time ....

Do you have any solutions or suggestions for this ...

I have used the connection in the following ways. ... 

  public class student_operation {public SqlConnection cn = new SqlConnection (); Public SQL Commands CMD = New SQL Commands (); Public SqlDataAdapter Ad = New SqlDataAdapter (); Public Dataset RS = New Dataset (); Public dataset rs1 = new dataset (); Public student_operation () {// // TODO: Try add constructor logic here // try {cn = new SqlConnection (System.Configuration.ConfigurationManager.ConnectionStrings ["myconnection"]. ConnectionString); Cn.Open (); } Hold (exception) {if (cn.State! = ConnectionState.Closed) {cn.Close (); Cn.Open (); }}}}}

Make sure you are opening up and close your connection Are there. Do not worry about connection "pooling" Net will handle it automatically for you. Just open the connection, do your work and turn off the connection (even if it's in the stable part).

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
