Dynamic compilation for ASP.NET Application (Building a "module based" CMS)



I have asked a simulair question before..but this time its still rather different...atleast i think so..

I will try to state an example..

What if I have built a CMS for instance..and this CMS is "module based" like Drupal, which means that you can download packages, also known as modules, and simply put them in a speicall folder and then the module is installed...

the problem with this in ASP.NET is as far as I know that it whould require the application to get recompiled...

One way od doign this is to simply download then whole page, open it up and visual studio and add the module/package, and then recompile the project..but is there anyway to recompile the project directly on the server?

To put this even more generall...how whould you guys create a module based system that doesnt require the user to download it the whole page to a local machine and then add the module and then recompile it and then put it back up on the server?..any suggestions?

And yeah I know...or well,atleast as I know...this sort of things aint ASP.NETs strength..but still throwing it out there to see if someone has solved it :)

Thanks in advance!

New to asp.net looking for advice on building application framework for database web app


Hi everybody, I am looking to build a web application from the ground up. I have done a bit of research, however I just thought I would post here to see what kind of responses I get. Any input is greatly appreciated! I will give a brief description of the type of application I am trying to build.

It will be a database web app for managing clients and financials of those clients.

The application will need a secure log on system for approximately 160 end users, with the ability to change permissions for each user given their individual rights.

Depending on the type of user created they will have access to 1 of 7 unique application modules within the app framework.

A data dictionary will be designed and created prior to starting the project as the 7 unique application modules will have common database fields and custom relationships.

Based on this information, what asp.net tools, libraries or books would you recommend using? Thanks in advance!

Problem making Role based Menu in MVC application



 I want to make Rolebase menu in MVC such that if user doesnot have permission for some action then that Action name shouldnot be shown in the Menu.

 I have used the code in the url(http://forums.asp.net/t/1566328.aspx) in my MVC application.My application is a Discussion Forum(in MVC) same functionality as in this forum forums.asp.net

 I have used Controllers for post, thread etc.In each controller there are some actions that are using [Authorize(Roles)] attribute

 but this coding does not count  those Actions in Controllers having Authorize attribute according to the url http://forums.asp.net/t/1566328.aspx 

 In the code, Authorize attribute is applied to Controller class, but my requirement is of Applying Authorize attribute to some actions in controller so that some are available for all users and  some links are available rolewise.Now what is the solution for that?



ERROR [HY000] [Informix .NET provider][Informix]Database locale information mismatch


Hi, there is an upgrade to my infimacs server and my web application encounter this error after the infimacs is upgraded.

Below is the information on the server before/after the upgrade.

Before            After

---------       -----------  

Solaris 8      Solaris 10

IDS 9.40     IDS 11.50

The web server where the web application hosted is running IBM Informix Connect 2.81. There is no such error before the upgrade is done.

As a developer, i have IBM Informix Client-SDK 2.90 installed on my local pc and debug the page where the read is needed from infimacs but no such error found.

The error come out only when it is hosted on the web server where IBM Informix Connect 2.81 is installed.

I have gone through many articles and it suggest me to set the environement  variable in the server :  DB_LOCALE=en_us.819.

I haven't try this solution but i think that this might not be the best solution.

Is it possible to to to have this settin

Data Access: Building a Desktop To-Do Application with NHibernate

.NET Internals: Tailor Your Application by Building a Custom Forms Designer with .NET


The design-time architecture of Windows Forms in the .NET Framework has made development much more flexible than it had been with MFC. With Windows Forms, you can drag one of your custom controls from the toolbox and drop it onto the Visual Studio design surface and even though Windows Forms knows nothing about the control, it's able to host it and let you manipulate its properties-not possible in MFC. In this article, the author discusses what's going on under the covers as you design your forms and then walks through the creation of a bare-bones forms designer.

Windows Forms: Give Your .NET-based Application a Fast and Responsive UI with Multiple Threads


If your application performs any non-UI processing on the thread that controls the user interface, it may make the app seem slow and sluggish, frustrating users. But writing multithreaded apps for Windows has long been restricted to C++ developers. Now with the .NET Framework, you can take advantage of multiple threads in C# to control the flow of instructions in your programs and isolate the UI thread for a fast and snappy user interface. This article shows you how. Also, it discusses the pitfalls of multiple threads and presents a framework for safe concurrent thread execution.

Security: Unify the Role-Based Security Models for Enterprise and Application Domains with .NET


Role-based security allows administrators to assign access permissions to users based on the roles they play rather than on their individual identities. These privileges can be used to control access to objects and methods, and are easier to identify and maintain than user-based security. The .NET Framework provides two role-based security models, which are exposed as two namespaces: System.Enterprise-Services and System.Security.Permissions. Presented here is a comparison of the two options and a discussion of when each is the right choice. The author also demonstrates the process involved in setting up access security and discusses role memberships.

Upsize Your Database: Convert Your Microsoft Access Application to Take Advantage of SQL Server 7.0


What if you need to convert an existing Microsoft Access 97 database application into a true client-server application that is based on a SQL Server back end? If you know a little about Visual Basic and SQL Server, it's easy to make your app take advantage of the power and scalability provided by SQL Server 7.0. Using some concrete code examples, this article takes you step by step through converting the native Jet queries in your Access application into stored procedures and pass-through queries that SQL Server can use. You'll also learn how to pass on parameters when your client-server app calls these SQL Server stored procedures and queries.

An example of packaging web application containing database upgrade SQL file

A few months ago, we have a blog talking about extending the web publishing pipeline to package database project deployed SQL file.  In this blog, I'll show step by step example of packaging web application with SQL Server database upgrade SQL file using Visual Studio 2010.  This way, we can generate a web package with incremental SQL script to certain database version.  The scenario may help distributions of a web upgrade package which needs to be installed on many different locations, each with their own SQL server database.   1. Create a Web Application Project 2. Add a new "SQL Server 2008 Database Project" to the solution 3. Prepare a development database, such as my test1 database as the following: 4.

Looking for Clarification - Using a SQL Database MDF in an ASP.Net Application

I am looking to understand how to use Database files with ASP.Net web application projects. Very similar questions were posted, but I couldn't find quite the clarification I am looking for, so here's another post. I've been programming with ASP.Net for a while, but have always been in an environment where I had a full SQL server setup, and the databases were not file format. For the purposes of this project I am trying to keep it in .MDF format so that I can pass it on easily to my customer and let them do what they wish with it. The project is in Visual Studio 2010, a simple ASP.Net 4.0 MVC2 application that is to use EF 4.0 for persistence. Background Issue First thing I did was add a database to App_Data folder. It shows up on Server Explorer and I can manually add tables via Visual Studio - this should mean that the connection string and permissions and such fine I would think. So, next step. I created an Entity Diagram, built everything "model first" and used the Model to generate the database schema. Using the connection string in web.config, the generated SQL code runs, and says at the bottom of VS, "Disconnected". I go to the Server Explorer, and sure enough there's a red X next to the DB file. I expand the MDF, the little black arrow comes back, showing me I am connected. I try to run it again... and it does the same... "Disconnected"

problem rename sharepoint 2010 search service application admin database

Hi all, i have a problem that hopefully someone has an answer to.  i am not too familiar with sharepoint so please excuse my ignorance. we have sharepoint 2010 on a windows 2008r2 server.  everything seems to work fine.  but as you know, the default database names are horrendous.  i have managed to rename all of them, except for the "search service application" admin database. the default is: Search_Service_Application_DB_<guid> the other 2 databases (crawl and property) were renamed without a problem. we are following the article from technet on how to rename the search service admin db (http://technet.microsoft.com/en-nz/library/ff851878%28en-us%29.aspx).  it says to enter the following command: $searchapp | Set-SPEnterpriseSearchServiceApplication -DatabaseName "new database name" -DatabaseServer "dbserver" however, i get an error about identity being null.  no big deal, i add the -Identity switch and the name of my search service application.  but the real problem comes the error it throws:   Set-SPEnterpriseSearchServiceApplication : The requested database move was aborted as the associated search application is not paused. At line:1 char:54 + $searchapp | Set-SPEnterpriseSearchServiceApplication <<<<  -Identity "Search Service Application" -DatabaseName "ShareP

How to show random information with C# from a SQL Database?

I have to do the following in my web page.  Any advice and how to do this please with C# I have a table where I have a column for different states (NY, NJ, etc).  People can join the group (in my page) for each state (the state where they live).  So I have to display the newest members for each state. So the way it should work is, every time the page is refreshed/reloaded it should show the state name as a header text and the first 5 newest members for that state.  This should be random, for example initially when the page is loaded say it will show state: New York and the 5 recent members like Stacy, Laura, Mike, Sam, Mathew. Then when the page is refreshed it will show another state like State: california and the recent 5 members All the information comes from the database How should I do this?
