.net - Database cascading error -

-

I have three tables in my database: Events, Jobs and Collective Antiques.

The FK was pointing at the jobs of PK.

In both events and jobs, non-blankable FK (which is also PK of the table) for Collective Antilles' PK, these FK relationships are set for a waterfall on updating and destroying. In fact, when you remove Collective Entity, I want to delete the relevant event and / or job.

Now I am trying to change Events to Job FK relationship to set tap on updates or delete, but I get the following error:

Error SQL01268 : .Net SqlClient Data Provider: Message 1785, Level 16, State 0, Line 1 Submitted 'FK_Events_Jobs' table 'events' may be on 'foreign currency key' Specify an action on the circle or multiple casted path DELETE or an action update Do, or other foreign keys Modify the barriers.

Where is the cycle? How can I avoid this problem that the description described above is the only effect I want. (I'm ready to make changes to avoid other unexpected side effects.)

You have a very similar situation ... after being removed from the collection, efforts are being made to remove from the incidents, which is going to endeavor to remove jobs from the events due to the FK till the job. But due to removal of containbets, efforts are being made to remove jobs due to FK. Doing the job twice in the waterfall is a problem.

I could be a little clever because you did not include your schema, but the general principal should be correct.

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

By using Wordpress I have created a multiple selection box so that users can select categories to exclude. When the page is initially loaded, I see my predefined default option.
