I am implementing an eCommerce application using ASP.Net. I would like to know if custom Google search is sufficient enough or if we plan to go implement our search functionality.. how do we go about doing it?
View 3 RepliesI have a textbox and what I would like to implement is basically a situation similar to what you have in google when you type in a word. In otherwords,
in the textbox when you type in J, it should generate a list of names that starts with O in alphabetical order, then next when you type in o, so that now you have Jo, it should generate a list of names instead that now starts with Jo in alphabetical order, then again when you type in h, it should generate a list of names that starts with Joh and so on.
I've started some preliminary work on getting a Google-like search functionality into my app - ive never done anything like this before so i thought id be a good idea to run by what im thinking of doing at a high level
1) Using MS SQL 2008 w/ Full Text Search Enabled
2) ASP.NET MVC 2 app is using the Repository pattern, with Linq to SQL for data access I'd like for the user to put in one giant text search value, and the full text to do a search over multiple tables and return a mixed result (Employees, Organizations, Offices, etc)
3) I have a simple stored proc that does a Full Text Search on *one* table that looks like this:
[Code]....
4) My Linq to SQL datacontext calls this SP and which works well enough, i have no inflection or ranking going on but ill add that in later...
Q: How do i handle searching over *multiple* tables, doing some digging around it looks like Full-Text doesnt really allow for searches to span over more than one table - which kinda sucks..although ive seen some workarounds
Q: Is it ok to do a Full Text Search for every table i plan on searching through, and combining the results at the business layer (maybe using rank as sort)? I've heard of things like LUCENE but id really not like to do that at this time.
I'm working on a project that involves exporting HTML to PDF. I was told that this can be accomplished with a a free library called ITextSharp:http://itextsharp.sourceforge.net/This looks like it's actually a JAVA-based interface. Does anyone know how to actually inistall this and reference these dlls in your ASP.Net project? Maybe there there's a different version of ITextSharp for .Net that I missed...
View 3 RepliesI am about to deploy an ASP .NET application (developed with LINQ-to-SQL). I have taken following precautions: Database access via user with limited access, however, since application is to access the sensitive data, I can't deprive this limited access user from it Database server is not exposed to external network - is hiding behind DMZ and all external ports are blocked I have done thorough security testing of the web-application; SQL Injections, rights management, illegal data access (via post/get data tempering) Application is operating on SSL
1 - I am using ASP .NET authorization API; any recommendation for avoiding session hijacking (in case someone some-how gets to know the session key). Is there are way to change the authentication cookie less prone to threats? Say like, changing it after every request? (I know I am get very conscious about this particular item)
2 - Data in the database is not encrypted. To make things ultra-secure, I am thinking about implementing transparent data encryption. Can someone share his/her experience or a link about implementing data level encryption with SQL Server 2008 along with pros-and-cons?
3 - Recommendation for storing connection string in web.config. Is using integrated security better then using encrypted database connection string?

What is the best way of implementing it without memberships in asp.net ..
In my asp.net application, users are created by the administrators & those users need to log-in into the system using their own email/password or openid. So what is the best option to implement in this scenario?
I mean, as users can't register them self,do administrator required to associate each openid with the users & what kind of table structure do I need?
And do I also need the log-in interface like that of [URL] showing multiple types of authentication(default & openid from various providers)?
want to make sure I am not assuming something foolish here, when implementing the singleton pattern in an ASP .Net web application the static variable scope is only for the current user session, right? If a second user is accessing the site it is a different memory scope...?
View 4 RepliesI am developing a web application using asp.net 4.0, vb.net 4.0 and Sql-Server 2005 as backend. I want to implement read only or read/write permissions for a particular logged in user. Ex : I have a Purchase order page, now I want to assign only view permissions to a particular user and read/write permissions to another user. what would be the best way to do it ? Use authentication and authorization provided by .Net or implement custom authentication and authorization ?
View 2 RepliesI'm writing an ASP.NET MVC site where I need to have a "Tasks" application that runs alongside the website. Such a "Tasks" application would collect data at set intervals and insert it into the database.
Of course, I could write a simple Console Application and use the Windows Task Scheduler to run it, but my site is being hosted by GoDaddy and I only have medium trust permissions.
Are there any methods for implementing such functionality while not violating medium trust permissions?
One method that I'm considering is a method in the site itself that gathers data, waits for a long time, and then gathers data again. Would that interupt users' connection to the site?
I've been tasked with implementing a JSON feed on an asp.net website that will be consumed by 3rd party apps (such as IPhone, Android, etc) and I'd like to follow best practices.
An example of what I'd like to achieve would be something similar to: [URL]
I've chosen the JSON.net api as this seems to be highly recommended.
My Google-fu must be failing me as I can't find a single full example code for an Asp.net web application with JSON.net implemented on it, so I've no real concept of where to begin.
My question is fairly simple:
Should I create this sort of feed as an ASPX, or ASHX file? Or even a .NET Web Service? (Remember that the tools that will be using this feed are on external apps like IPhones, etc)
I created a test feed in both ASHX and ASPX format ... here is the code (I'm using Subsonic to populate the collection) ... are either of these along the correct lines?

We are developing a custom .NET directory listing style application for a client and we require a powerful search solution. The application will be built in ASP .NET C# on SQL Server 08. The application is based around data which users to the organisation can enter in a profile management style area. Fields can be textboxes, textareas, selection boxes, multiselects etc. A user from the main website needs to be able to use the search function to find a result, but this result should search the entire database and not only base the results on one or two fields. It could be anything within any of the fields the user can fill out or select etc.
Can anyone help me find a possible solution for a .NET powered search engine we can use for this application? It must be preferably C#, running on .NET 3.5 and SQL Server 08. The database is a completely custom built schema and so there is no schema example to show or that can be shown. If you need more information to provide a satisfactory answer let me know and I'll try to provide some more information specific to what you ask.
How to impliment search functionality in static web application developed in c#, asp.net

View 5 RepliesI've built an ASP.NET MVC application with MVC 2.0 and Fluent NHibernate (hided behind repositories for some reasons). The application represents a quite complex domain with some different objects like users, messages, comments, files and appointments.
Now I want to implement a fulltext search which is enabling the user to find easily all types of content by simply entering a search phrase. When handling all that types of different objects in the application seperately, I now have to put them "together" for the search. That means the user makes no distinction between the different types, he just enters "xyz" and wants to get results in a list, comments mixed up with messages etc.
Option 1 is to create a search service which fetches the search result from the different repositories and prepares the combined output (sorting, paging etc.). But that's really, really expensive when the data behind grows (and it will grow).
So I am looking for an alternative solution. Currently I am working with SQL Server 2008. What I have found is lucene.net [URL], but I didn't invest much time yet.
I am working on a railway web application and I have following layers:
[Code]....
I pass Domain Entity Objects from Repository to Service layer and thinking of passing View Models from Service to Presentation layer. Website would require a login and after successful login I have to present a search screen with basic search (as default option) and option for advance search. Once user fills the
search criteria I have to gather data from DB & Web Services and present the results to user. User would select a particular Rail option and would move on to other additional options page BUT they should be allowed to change their previously selected Rail option by going back to Rail search results. I have to
always hold and present user's initial search criteria (basic and advance search options selected by user on the search wizard) on every screen and need these criteria in Service and Repository layers.
What is the best way to hold these search criteria and pass them from page to page within presentation layer and across layers? Should I create a View Model class for Search Options? Or a Domain Entity Object (I don't think so)? and best way to pass it across layers and from page to page with in presentation layer.
i want to search for data in informix using a like('%Name1%') from my .NET application. The query that i have written is something like this:
select * from tableName where columnName Like CONCAT('%',CONCAT('Name1','%')) ......
this query when run from the front end does not yeild the desired result set ......however when i execute it from the db level i get the correct result .... also an intersting thin that i noted is ...if i do a LIKE('%' || 'Name1' || '%') from the front end i get a syntax error ...however this works just fine when i execute the query from the db...... ive spent over 10 hrs trying to figure this out ......but have not found a solution for it on my own ...... also, the following works perfectly :select * from tableName where columnName LIKE CONCAT('%','Name1') .....from the application...
likewise select * from table name where columnName like CONCAT(Name1,'%') works ...........* the vale fields need to be replaced with a '?' in the front end ...informix automatically replaces it when executing the command statement....so the commantext for all informix commands look something like this :
select ColumnName from tableName where columnName1 LIKE CONCAT('%',CONCAT(?,'%'))
parameter is 'Name1'

View 1 RepliesI have just deployed a MVC web application onto our intranet. The application is hosted on a Win 2003 R2 SP1 server and running on IIS 6.0. Everything works fine within the application. But our intranet uses the windows Indexing service for providing search functionality on our intranet website.The search brings up related links to files within the MVC web application. But the problem is the links don't work as MVC urls do not point to absolute files.Is there a way to resolve this?
