c# - Make Hashtable immutable -

-

How can I create derivative classes from Hashtable, objects which can be added, but can not be removed or can not be changed?

P>

What to do to override me and especially how I override the [] operator Can i

At least, you clear , remove , property value and index / code> item . You can override indexor item using syntax: 

  override the public [of this object] {{Setup implementation} Set {// set Implementation}}

You need to override the clear so that a user can not clean the hashteble. You need to override the remove so that a user can not get hit from the hashtable, you need to override the value because one user is Icoding You can use that which has been returned to modify the value in the hashtable, you have to override the item for a similar reason.

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 ;!

-
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
