linq to sql - How can I clone (or copy) a object to another one, but don't copy PK attribute? -

-

I'm trying to copy all object attributes to another object, FOX example: 

  person p1 = new person (); P1.name = "John"; P1.sex = 'M'; Person p2 = new person (); P2 = Utill. Clone (p1);

The problem is that the person unit has an identity PK 'codprison' and I do not want to copy this PK. Is there a way to clone / copy an object, but it does not have a copy of its PK attribute ??

Thank you!

  1. Make sure that Util.Clone (person p) codeproduction attribute
  2. Clear the attribute after the clone method
  3. Create a new person object, especially starting the special properties.

asp.net - Javascript/DOM Why is does my form not support submit()? -

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
