  • How do you lock down & secure files stored on server in ASP.NET?

    - by Jon
    How do I go about securing files that are stored on the server? We have an ASP.NET app which generates PDFs. These are not stored in the wwwroot folder but in another folder i.e. C:\inetpub\data. This provides more security but maybe not enough. The ASP.NET/IIS process will need write access to this folder so it generate the PDFs there. Once the pdf is generated, it can be viewed using an ASP.NET form called viewpdf.aspx with the file to be viewed add to the query string like so viewpdf.aspx?FILE=mynewfile.pdf. This is loaded from a gridview. The full path to C:\inetpub\data is resolved and loaded in the Page_load event of the viewer page. Now I'm wondering how to secure this. Anybody could just view the file. Not by entering in the URL, as it won't been seen by IIS (its not in wwwroot), but could change the querystring in the viewpdf page. How do I stop anybody hacking this?

  • How to transfer large files from desktop to server ( .NET)

    - by rahulchandran
    I am writing a .NET 2.0 based desktop client that will send large files ( well largish under 2GB) to a server. Need to develop the server as well. Server can be on any technology It should be secure so an underlying SSL stream is needed What are my options. Any obvious caveats etc I should be aware of To my mind the simplest solution is to open a tcp\ip connection over SSL to the server and send n packets each of size M bytes and then have the server append the chunks to the file and finally send an EOF packet as well IS this horrible. Will the perf suck on the server with all these disk writes What are any other clever options. I am limited to .NET 2.0 on the client if I did move to a WCF client will it buy be something magical and cool for this scenario Thanks

  • What FIX implementation do you recommend for use with .NET

    - by Ajaxx
    I am reviewing implementation choices for FIX when using .NET. A few obvious choices come to mind, but I want to know if there are other options, better choices or if we've made the same decision as a lot of you. QuickFIX - Stable, C++ implementation - so you've got unmanaged code to interop with. FIX4NET - C# implementation - seems to have some gaps in its implementation. DIY - Chime in here if you've made your own FIX engine Let me throw in some caveats here. I'm not looking for sub 100 microsecond processing. Performance is a requirement, but not so much that it's driving my decisions. A solid product that is stable, performs well and is flexible enough to deal with vendor specific dialects is the sweet spot. The more we can do in .NET the better.

  • Thread-safe blocking queue implementation on .NET

    - by Shrike
    Hello. I'm looking for an implementation of thread-safe blocking queue for .NET. By "thread-safe blocking queue" I mean: - thread-safe access to a queue where Dequeue method call blocks a thread untill other thread puts (Enqueue) some value. By the moment I'v found this one: http://www.eggheadcafe.com/articles/20060414.asp (But it's for .NET 1.1). Could someone comment/criticize correctness of this implementation. Or suggest some another one. Thanks in advance.

  • Popular .NET Compact Framework open source applications / components

    - by ollifant
    In my company I am responsible for the development of a .NET CF application which runs on top of Windows CE. We have invested much time in the development of a GUI framework, a top-level design which handles authorizations and navigation on the device, a IoC customer, ... Now I was wondering if there are any other projects which show kind of best practices (for example what the prefered way of GUI drawing is). In the following there are some which I know: UI Framework for .NET Compact Framework 3.5 Project Resistance Amplite Application Port from IPhone* Several twitter clients CaveMen from LightWorkGames* What applications / components do you know? * actually not a application, but definetely worth to take a look

  • Does anyone have an updated version of the SQLite .NET assembly, ie. SQLite 3.6.23.1 + possibly .NET

    - by Lasse V. Karlsen
    I'm at my wits end with the best .NET assembly version of SQLite, the one found at http://sqlite.phxsoftware.com. The only maintainer doesn't seem to have the time to update the library and it generally takes months, if not more, for newer versions to surface. Luckily, he has published the source code, so I'm hoping that someone else has made his/her own copy of it, and made the changes, and would be willing to share a copy. I've seen comments on the forums for the library to this effect, but sadly even the forum software seems to be grinding to a halt these days as password reminder emails seems to be lost to the big void, so I can't ask the few there that has said they have done it. So I'm here, hopefully the big userbase of StackOverflow can help. What I'm looking for: Updated with the latest changes to SQLite, ie. SQLite version 3.6.23.1 Possibly built for .NET 4.0 (I can do that if I can get a copy of working source) Does anyone have, or know of anyone, that has done this?

  • vb.net : is it possible to connect to sql server 2008 via odbc but not through vb.net code?

    - by phill
    I'm supporting an old vb.net program whose database it connected to was moved from SQL Server 2005 to SQL Server 2008. Is there a setting on SQL Server 2008 which will allow ODBC connections to access the database but not allow VB.NET to connect to it programmatically? the error i keep receiving in the app is: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server) however I can connect to it when I create a system dsn to the sql server instance and through VS2005's Tools Connect to Database. Here is the code I'm using to connect: dim strC as string strC = "data source=bob; database=subscribers; user id=bobuser; password=passme" dim connection as New SqlClient.SqlConnection(strC) try connection.open() catch ex as Exception msgbox(ex.message) end try connection.Close()

  • Referencing control on one form from another form VB.NET

    - by Tom
    My gosh man, why is this so complicated in VB.NET? As you can guess, I'm kind of new to .NET and just want to reference a control on one form from another. Usually I would just do Form.Control.Property but that doesn't work and every example I've found through Google doesn't work for me. It just seems overly complicated with public classes, etc. Is there a more simpler way to do this? I'm ready to throw in the towel and just use a global variable at this point. I have the form containing the control I want to reference, frmGenerate which has a textbox called txtCustomerNo. From this form through a button's click event I want to show another form, frmCustomers, and have that form reference the value in txtCustomerNo. frmCustomers.ShowDialog() It has to be something simple that I'm just not grasping. Thanks.

  • FTP/SFTP module for .NET

    - by Angrius
    I am designing an auto downloader using .NET and C#. I was wondering if there is a decent/robust FTP/SFTP module out there that I can use, preferably free of charge. EDIT: I probably should've noted that I am looking for answer from somebody who tried several and found one that works very well. I currently use .NET wrapper for libcurl for FTP and it does not behave right. For example when I connect to FTP site with Filezilla and provide a path, it finds directory just fine. With libcurl, i get a header for 404 page saying path cannot be found. I am guessing that Filezilla gets 'home' directory correctly, and libcurl puts me to the root (i tried no path, and i had no permissions to access that directory). But anyways, I just don't know enough about FTP itself, so I would like something that just works. Thanks!

  • Call a JavaScript function in a Google Chrome window from a vb.net program

    - by user1464827
    I am having a real problem with this. I want to know if it is possible to run/call a javascript function in a Google Chrome web browser window from a VB.net application. The scenario is that i want to monitor the pc activity (which i know how to) and then if a certain event is met (for example, high ram usage) then it calls a JavaScript function in a Google Chrome web browser window so the website is updated. Sort of like a bridge. The only bit it need to know is the vb.net code for how to access a chrome window and invoke a javascript function if its possible. I assume i will need to use process handlers? Any help is appreciated.
