View 3 Repliesit's possible to protect aspx page from modification in a production environment?
I explain: We are developping a web application that is installed in our customers environments so once it's installed we don't manage it.
This application manages critical and encrypted data that the IT (of our customer) should not have access to, for instance their customer's password. So I would like to know if it's possible to prevent any modification of the aspx page to insert script to retrieve session data or catch keyboard entries once the web application is installed.
I have started to get confused with the setting and security issues of asp.net. Hope someone could answer me. Problem 1: I am curious why we have to encrypt connection string, appsetting and more in the web.config file even though file listing is set to "not allowed" on server setting. Does it mean some strangers can still view and steal such file from server? Problem 2: I know that session id is sort of protected but could
hacker be able to change the information inside ? Let say hacker browser my webpage and some data are stored in the session cookies, could they change the information inside the session cookies?

I have a text file with tab as delimiter. There are about 20 fields in the text file and the file size is about 150MB-200MB.
I need to filter out each row in the textfile based on its field criteria, For Eg: the i should ignore the particular row if the Field A is empty.
I know that by reading out the text file row by row it will be certainly slow.
how to read out the text file fast and also how to do the file processing for the read out text file?

View 2 RepliesI'm rather new to the topic of designing web applications, and during my attempts to create something i stumbled upon a rather tricky question. For my application I want to do a user control with which user will be able to select a file from a hard drive and upload details about this file. I dont want the user to send the whole file, just the details about it. For example lets say user selects a mp3 file. I dont want the whole song to be uploaded but i want the details about that song like the Author, on Album etc. Is something like this possible without uploading the whole file?
I tried looking up that topic on the internet but i found nothing... though i dont believe I am the first one with such a dilema;]

I have to create a windows service which Monitors a specified folder for new files and does someprocessing on it and moves it to other location. I started with using FileSystem Watcher. But my boss doesn't like FileSystemWatcher and wants me to use polling on Timer or any other mechanism other than File System Watcher. I am confused right now. It would be great if anyone could point me to some examples for how to monitor Folders without using File System Watcher in .net environment.
View 8 RepliesI am currently writing a gridview to an excel file, but i cant make it password protected (or the password is too easy to break).
Is there another file type that i can write the gridview data to which can be securely password protected at the same time?

View 1 RepliesI have an application that lets the use upload a pdf, I wanted to put a limit on the size the pdf can be. If the user tried to upload something too big I wanted to display a message to the user. I am trying to use a custom validator where it checks the size of the file and if it is too big it will set the "IsValid" to false. Is this the correct way to go about doing this? Is there a better way? When I test it, everything works in IE 8 and FF, but it does not work in IE 7 and can't figure out why.Here is what I have so far, this is on my aspx page:
