Am trying to open a .pps/.ppt file through my vb.net code.....due to secure reasons this file is password protected,
However i will not like the end user to put a password when accessing through my application.
Hence i want to pass a password as a parameter while open such a password protected file.
Here is my code.

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)?

I 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'm looking to deploy a web app and I have a simple question about the <location> tag of the web.config file. For the moment, I want all the pages to be password protected and I've created a simple login page with the login object. I've put all my .aspx file in a directory called AppMyPages and I've put this in the config file:
<location path="AppMyPages">
<system.web>
<authorization>
<allow roles="tester" />

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. The access database I would like to connect to does not need a username or password, only the shared location does.

I am trying to create a password generator which will do the following:
1) Generate a simpler password, than just completely random as this is what currently the Membership classes do if the above cannot be done then how can we kind of mimic the randomness but use a predefined list of perhaps common words?
2) if we have a Regex expression, is there any way a password can be generated randomly complying with that regex expression? (something extra to think about)

We are using Ultramain(DB: Oracle 10g and Language: Progress) as a MRO application for aircraft health check. Ultramain has more than 3000 users and using this application around the world. Users are forgetting the password frequently and we are getting the mail minimum 10 password reset from the user. I have planned to create a website for reset the password themselves if user valid. Only one button in the website called "RESET". If user click the reset button, it should check the user have already access using the table called "USER". If users have access, it should check the user authentication. If users does have access, the message appears "You do not have an access". If authentication success,update thepassword from the table "RESETPWD" to application table "USER".
Table:
USER --- application user table
User_ID
User_name Password
12345 Nihar ahlnhTczpihljbIn
Table:
RESETPWD ---- temp table for encrypt and decrypt password.
Encrypt
Decrypt
