View 4 RepliesI am looking into making a voting system for an event.
I would like to base the voting system off of MAC addresses. I would like to get the voters mac address, check to see if they have voted within the last 5 minutes, if they have not, let them vote and add their mac address and current date-time to a table as a record. If they have voted within the last 5 minutes, i would then inform them and tell them to try again later. If it has been longer then 5 minutes, i would clear their record from the database, let them vote and add a new record with their mac address and date-time.
The problem with using IP, is that most of the people voting will be on the same network (large organization) and i believe the ip the website would pickup would be the same.

Im building a CMS (ASP.NET C#) and I am currently looking at how to implement a module system. How is it done with most modularized systems on the web? The most important thing is that I dont want the modules messing with any of the core files. Example of a case:I have an ajax search method that is using a webservice method named Search; how can a module "add" its search results to the result list? If the core search only searches webpages and I want the search to also search products in the e-commerce module, how can it add the product search, and its contents, to the original search method's return list? Is that even possible?
Ive been looking at reflection a little bit, and it seems to be useful with running module code from within the core, is that correct?I have no experience with this kind of stuff, so a push in the right direction,

View 4 Replieshow this is achievable, not so much in the "build the whole project" as to how the reservation website gets quotes for all the flights from all the flight companies. I assume that in the website's code you have to use a webservice which will quote say website A, and get its ticket prices.

View 2 RepliesI wanted to create a custom class that inherits from System.Exception and adds a few properties and methods specific to the project.
The issue I'm seeing is that a standard try/catch block catches generic Exception class and the compiler thinks that converting that to my custom class is OK. However, at runtime if the actual error is something else like a a System.Net.WebException for instance, then at runtime it will not convert to my custom class. Then my own error catch throws an InvalidCastException.
Obviously the one thing I don't want to happen is to have my error logging methods throw errors on their own...
So, how can I convert ANY exception to something that my custom class can use?
Here's a code example:
Csharp Code:
[code]....
Now, this code builds just fine... VS2008 and VS2010 have no issue with converting an "Exception" to "MyErrorClass", but at runtime it certainly doesn't like converting a "WebException" to "MyErrorClass"...
