i have table data which i am currently writing to an excel file, but i need to be able to securely password protect the file. Ive been told excel passwords are easy to break, so is there another file type which i can dynamically write to and password protect for emailing elsewhere (and requiring receiver to type password in to access it)?

View 2 RepliesI have a website that has anonymous authentication enabled. Now for a particular folder I want the users to be logged in with a userid and password. The user id and password is going to be same for everyone.
Eg user id is TEST and Password is answer. How can I do that?
I went in to that folder ->properties->directory security->edit-> And I disabled the anonymous access
But where should I add the User Id and Password? Under which option.
I'm running IIS 6 with ASP.NET 2.0.I enabled windows authentication for a folder in a website and gave permissions to a user. When I navigate to the page, the passowrd prompt pops up as expected and when entered correctly, the page loads. The page contains a file upload control. When I try to upload a file, the password prompt keeps popping up. ultimately it ends up as a 401 error. The user account does have write permissions to the floder, so I'm not understanding why I can get to the page with the credentials, but can't upload anything to that folder.

I'd like my application to query a csv file from a secure website. Currently I have the user login to the site, manually query the csv, and have my application load the file locally. I'd like to automate this by having the user enter his login information, authenticating him on the website, and querying the data. The application is written in C# .NET. The url of the site is: https://www2.emidas.com/default.asp.
I've tested the following code already and am able to access the file once the user has already authenticated himself and created a manual query.
System.Net.WebClient Client = new WebClient();
Stream strm = Client.OpenRead("https://www3.emidas.com/users/<username>/file.csv");
Here is the request sent to the site for authentication. I've angle bracketed the real userid and password.

I would like to connect to a password protected shared location that has an access database using an ASP page. I have the user name and password needed to connect to the shared location but I am not sure how to set up the connection string in order to get this done.

Spent ages trying to get this right but am struggling now. I have a list box and textbox, I can happily enter Email addresses into the textbox which are saved into a text file and populated in a list box. I want to be able to select a list item and delete it, along with it's record in my text file. I was going to do it by on the delete list item / button click, it delete's the text file and then writes and a new one with the remaining list items in the list box. Unfortunately it's re-writing the file but either not including the remaining list items. Here's some examples of what I've changed and what populates the text file:
StreamWriter1.WriteLine(Addresses.Items); - System.Web.UI.WebControls.ListItemCollection
StreamWriter1.WriteLine(Addresses.Text); - A blank line?!?
The code is below. The reason I wouldn't allow the user to delete the first list item is because I thought the code was working ok but for some reason putting in a blank line to start with, and if I deleted the line it'd delete all file content. No, I don't know why I thought that either.

Based on this piece of code, I want to do exactly like this demonstration. However, correct me if I'm wrong but if two or more users somehow simultaneously access the web page at the same precise nanosecond in time, then wouldn't we have a race condition? So is this piece of code valid? How would I correct this to make it thread safe?
