Security :: Not Extending MembershipProvider Class And Putting All This Methods In Some Unique Class And Call Its Methods Then?

Sep 16, 2010

I am beginner in web applications development. I started one little project and host it on source forge "https://homoco.svn.sourceforge.net/svnroot/homoco". And I started implementing authentication in this application to learn how it works. From my experience people never use out of the box things so I want to implement this stuff alone (like in real world projects). So some questions:

1) Is there any reason to use membership out of the box? To use database table schema, stored procedures etc. that tool generate for developer. I think that this lower control over code and I decided to implement it my self. I don't know if I am right.

2) Is my approach in this demo project good or bad (if someone have time I like to do just a little code review)? I created database based on business rules. Not using database schema that membership provider require. Extend "MembershipProvider" class to satisfy my needs. Implement queries to database myself.

3) Now, this question is a little wired but I have to ask it. If we make custom Membership Provider and do sql queries alone, implement all MembershipProvider class methods ourselves, and in application use Membership.blabla() why is this approach different from not extending MembershipProvider class and putting all this methods in some unique class and call its methods then? I hope that someone understand what I ask here.

I am sorry for three questions, but I really trying to find the best way to implement this feature in my demo project like it is a real world application.

C# - SQL Server 2008: Use A Constraint?

Mar 9, 2010

I have a table with three fields, User, City and Country, where exactly one of the fields must be non-NULL at all times. Can I use an SQL constraint for this or should I rethink what I'm doing?

The scenario is that my database should contain documents that can be attached to users, cities or countries. So a row in this table contains exactly one document for either a user, a city or a country. However, one should be able to search for all documents as well, regardless of what entity it has been "attached" to.

The reason I'm not using three different tables instead is that I want to avoid having to JOIN the three tables when searching for documents in all of the three places. I'm imagining that the kind of denormalization I'm attempting to use here will improve performance.

- is it any constraint in SQL Server 2005 to help me check whether parent it is refer by student table? The concept i want to use is something like delete constraint in SQL Server 2005 mean it is not allow to delete a person who is refer by a student in STUDENT table.

SQL Server :: Special Insert Constraint Rule For Two Columns?

Oct 19, 2010

I have a SQL Server 2000 table with 7 columns and would like to add a constraint that prevents a row being added with the same value for both Col2 and Col3.

So, for example, if Col2 = 205 and Col3 = 5, then the constraint should prevent inserting another row with the values for Col2 = 205 and Col3 = 5.

The following is an example of what I would like to prevent:

Col1 Col2 Col3 Col4 Col5 Col6
1 205 5 1 1 1
2 205 5 0 0 0

Exception Handling From Private Class In User Control?

Apr 2, 2010

I am part of a team that is developing a SharePoint web part. My task is to create a user control which will ultimately be wrapped in another class for presentation in a web part. Because of these requirements, I must fit all of my code in a single user control.To organize my code in the code-behind, I created a few private classes for the different objects which are represented in the database. I want to add some exception handling whereby if some sort of DB exception is thrown I can update a message on the page informing the user of the problem.

My problem is that the page-level controls are inaccessible from the private class where I'm issuing the query, so even if I catch the exception I have no way of directly accessing a Label control to populate the error. I tried to create a baseclass with an EventHandler defined, but when I throw events from the private class I'm not able to catch them for whatever reason. I'm far from an OOP expert Here is a snippet:
ASP Code:
using System;
using System.Collections;
