I have a web site with an administrative section. All administrative pages are stored in a directory called "db/administration". There is only one user that I want to have access to the pages in this directory. That user's username is "system". Currently, I am using the following approach in my web.config file:

When I logged in as another user, I was still able to access pages under db/administration when I navigated to them through the browser's address bar. What am I doing wrong?
I've been reading through the fb developer api documentation and I'm trying to find out what would be the easiest way to post information on a website to the website's own facebook page. for instance - the assumed workflow is like this:
an admin user adds new content to the company website - and once submitted that content should automatically appear as a link on the company's facebook page.
Do I use the API, facebook Connect, a facebook Share button etc. Looking for some recommendations based on my assumed workflow. Project will be coded in c# (although I'm really looking for recommendations of which tool to use from someone's experiences with the api)

View 5 RepliesI am making a small file hosting website, and each user can upload multiple files, and will have access to just his files and can't access others files, for example by guessing the URL. Is there a way to secure files to have access by just the owner and no body else "may be website administrator also will have access"
View 3 RepliesI am developing a registration process which consists of 4 steps. Each step has its own action method. As such a user could type the url for each step as follows: bogusURL/Step1 //returns the View Step1 bogusURL/Step2 //returns the View Step2 etc... I would like to prevent users from gaining access to a step unless they have completed the previous steps. i.e. If they typed in bogusURL/Step2 without having completed Step 1 they should be redirected to the first step.
What is the best way to implement this?
I am downloading file from database using the following code. This code downloads an excel file from the database which has a macro attached to it when it is opened. This macro reads file name of the excel file and uses it for its computation. Everthing works file if user saves the file on his harddisk and then open if but if he directly opens the file from the dialog(by hitting 'Open' button) then file name of the opened excel file comes out be the name of the webform that has the above code and this leads to error in the macro. Is there any option through which i can control the name of the file if user directly opens the file from dialog or the option to disable or remove 'Open' button form the dialog?

View 1 RepliesI have an asp.net web app that uses forms-based authentication, a SqlMembershipProvider (using an encrypted password format), and a SqlRoleProvider. I need to know if it's possible to administer the users (create new users, assign them to roles, etc.) from a windows application - the powers that be don't want any administrative functionality in the web app itself.
Here is the membership provider definition from web.config:
[code]....
So, obviously, I have a Sql Server database that contains the users and roles for the web app. I'd like to create a separate windows app that references the web app assembly, and use the configured MembershipProvider, RoleProvider, and machineKey to create users, assign users to roles, etc. If that's not possible, I can duplicate the configuration settings from web.config within the windows app. But I don't know how to do this either.

we are working on a file download page. We want to download a file with a name with spaces and accents. Although the filename is shown correctly on the filedownload dialog, when we click open, the file name is shown with %e1%ba%a3n%20... on notepad. ('Save as' shows the correct name) This problem only happens in Internet Explorer.
Is there anyway we can Display the file name correctly (on the target application) after opening it (without saving) from file download dialog ?
We use this code to set the filename :
fileName = Server.UrlPathEncode(fileName);
Response.AppendHeader("Content-Disposition", "attachment; filename="" + fileName + """);

I'm trying to write come code for users to download files, but the files are located above the webroot (e.g. c:downloads)
I've found some code online that allows me to download a file via a url parameter/argument which is perfect, but the files need to be located within the website structure.

I have VB code that parses XML data from a webpage. Up until 2 days ago the XML data could be viewed right on the page and I could just grab the HTML source code to get the information. Now they have changed the page to a link button to download the XML file.
The problem is that when I click on the XML link I get the 'File Download Prompt' which asks me to run or save the file. I figured I could just save the file to temp directory and then open it up to parse it in my VB app but I can't figure out how to grab the file from the browser in my application.
