I'm currently working on a website being developing using ASP.NET and C#. I'm fairly new to ASP and C# so I apologise if I'm making an obvious mistake. The website I am working on has a login page which displays relevant PDF files. The client now wants to rebuild that by only displaying certain PDF files to the end user depending on their role. I have looked into Role based. My problem is I have over 100 PDF files which need to be displayed. What would be the best approach for this? Where would I store the roles in my DB?
Shall I do something like
if(User.IsInRole("Management"))
{
//Do something
}
Thanks in advance for your help and support
You can use the built-in Membership- and Roleproviders (e.g. http://logcorner.wordpress.com/2013/08/29/how-to-configure-custom-membership-and-role-provider-using-asp-net-mvc4/) or customize/override any of these in case you don't want the standard-table structure these providers bring with them.
If you combine the two providers and use the "default" implementation you can actually do it like you suggested yourself in your question, without any further implementation. It would be just configuration in your web.config then.
You can then introduce new roles and user/role mappings in the tables, that ASP.NET automagically created for you in the DB.
Here is some example how to override them: http://www.codeproject.com/Articles/607392/Custom-Role-Providers

I've created a website in asp.net mvc4 and i've put it online with specific domain name. Now my client asks to replicate same website on different domain name, and change some static texts/images to distinguish the 2 websites. I'd like to handle just one source code and deploy two times. How i can reach this?
We did this a few years ago with a web application. It was a pain in the a**. We had one website running and the resources were loaded after the user has logged in.
During the development you always had to think about that, split the resources always look for the logged in user etc.
It is just easier to copy the published application to a second folder and for the static texts use some kind of resource files that can be replaced on the fly.
As long as you don't have images and files that are a few gigabytes big it should be no problem to copy the compiled source code an the resources.
Though kind of a too late reply, but I just wanted to share some of my experience with you, you can follow these steps, it won't take too much of your time.
Identify the various text / images like logo for branding etc for which you have a requirement to make them tenant specific.
Create a table called tenant settings (tenantid, key, value )
Identify the pages that needs to be tweaked to look up from this setting than a hardcoded value.
Update these pages and provide a UI for each tenant so that they can change the values at any point of time
This way you can achieve the level 4 multi-tenancy with minimal effort to begin with.

I'm trying to create a wpf application such as a movies library because i would like to manage and sort out my movies with a pretty interface.
I'd like to create a library with all my movies getting information from the web, but i don't know how very well.
I thought to get the information from a web site, for example imdb, but i don't know if it's legally to capture html from page to get the nested information.
It's my first desktop application and I would also like to know if it is necessary to create a database within the project and then create a setup project with specified script for deploy it.
Sorry for the confusion but i would like to know too much things :)
Thanks a lot in advance.
The legality of web scraping is a grey area. See my question, "Legality of Web Scraping vs Normal Use" and the corresponding answers for some insight.
Even if the legality is not a problem, web scraping is a flimsy approach because the webpage structure may change without notice, making your application suddenly useless until you update it to the new format. You are much better off using some sort of web API (if the site providing the information offers it).
Whether you need a database or not depends entirely on what your application will be doing and how you design it - it's not something any of us can tell you.
Same goes for the setup project - in fact I wouldn't worry about that until you actually have a working application. Take it step by step and keep the scope within control.
Yes I did not think about api.
It's a great idea, maybe use "themoviedb".
But if i create an application based on it, that has to show all the movies that you have stored on your hdd and get , for example, the posters, the description and the ranking, i have to create a database according to you?
Thanks a lot.
I have created a document library with name "ARTICLES" in SHAREPOINT which stores documents. Now, I want to display the documents in Repeater and clicking on row it must display the document. And also all documents must be Downloaded in Application folder.
The application is pure asp.net application using c# and not a webpart or other.
Help appreciated!
thanks!
Although it might not suit your application (and it isn't exactly what you asked for), there is a much easier way of achieving what you described (suited for intranet applications where Windows Authentication is used).
It involves two parts:
In your web application add a IFRAME that points to your SharePoint library (using the default SharePoint web interface).
[optional] Add a custom master page to this library so that you can hide menus etc.
For many applications this solution is sufficient and saves you lot of trouble of coding the integration (and retesting it with every SharePoint update) decoupling your application from SharePoint. It also makes sure that the end user can use all SharePoint functionality such as uploading the changes directly from Word etc.
I want users to be able to upload images for profile pictures.
Are there any guidlines as to how this should best be handled?
eg - where to save the images? and folder structure to use.
- make it difficult for users to browse through everyones profile pics?
thanks.
I don't mean to be a wet blanket if your into writing this yourself, but I would just use http://en.gravatar.com
But to answer your questions directly:
Are there any guidelines as to how this should best be handled? eg - where to save the images? and folder structure to use. - make it difficult for users to browse through everyones profile pics?
Generally this is going to depend greatly on the setup of server environment. Do you have multiple web servers? Do you have a database server you want to use? Do you have an images only domain you want to use? etc.
The simplest approach is to write them to the file system and use code to retrieve them. By not writing these files into your web directory you can be sure that users cannot use this to execute code or script on your server. Useing an ASPX page to return the image content also allows you to relocate the image store at any time.
As for preventing browsing, I would just use a unique image identifier generated for each user. BTW, I would not use the user's internal "ID" field; rather, create a new id just for images.
If it is only to display a single user's picture, I would recommend to implement Gravatar instead of your own approach. There are plenty of articles out there how to implemt Gravatar with ASP.NET MVC the best.
If you really want to have your own solution, I'd recommend to give all of the user's profile pictures a random file name (for example with a GUID "3F2504E0-4F89-11D3-9A0C-0305E82C3301.jpg").
I'm wanting to create a user account creation section for unregistered users on our internet site. I want to ask the same questions as the CreateUserWizard control but have a few changes. I want the question to come from a question lookup table in SQL. The user will have a dropdown of available questions and I'll store the questionid they selected and the answer. Also, I want to store 1 other piece of data about the user (SSN).
My questions are:
1) Is forms based authentication an acceptable solution for this if using SSL?
2) Can I add additional columns (questionid and ssn) to the membership table or another table and how do I do that so I can save the info in the 'blessed' way? Will the solution have any negative effect if down the road I want to add password reset/recovery?
When adding columns, does it make sense to invoke Membership.CreateUser rather than using the CreateUserWizard?
Thanks!!
1) Yes it is. You can extend Membership with Profiles, and add any arbitrary fields you like
2) You can customize the CreateUserWizard a great deal, but behind the scenes it just ends up calling Membership.Create user. Personally, I would just roll my own (since it really isn't all that hard) unless you want to use the default wizard. But that is more personal preference then anything else.
NOTE: the link I provided for Profiles assumes you are using a WebSite project. If you are using Web Application projects, there are a few additional steps you can read about here.
