.net - Web Service Development - Implement File Encryption In A Desktop App?

Jun 4, 2010

I am currently working on a project that is very new to me, and I feel a bit over my head as far as knowledge base is concerned. My request is for references and information to help me expand my knowledge base, as well as recommendations for technologies and methods.I have experience primarily with Java, so all this Windows service stuff is new to me. I am not really asking for a how-to

The project is as follows: I am to develop an application in ASP.NET that runs as a process from start-up to shutdown. It will be checking some things in a folder, encrypting some files from that folder, and then check if internet connectivity is available. If it is available, it will be sending those files to a server (via a web service on that server, I believe). If it is not available, it will check every 'insert time interval here' to see if connectivity has become available, at which time it will send the files. Once the files are received by the service, the application will need to recieve some kind of confirmation from the server that the file associated with 'xxxxxxxxxxxxx' uniqueidentifier has been received.

Any explanation of the way that web services work or how to implement file encryption in a desktop app (resource load optimization is a very substantial requirement of this app).

Implement A Service To Download A Image File?

Dec 31, 2010

I am trying to implement a service to download a image file. The code does nothing but upload a file to the response with each client request.

There are no SOAP messages involved but I am planning to implement it as ASP.NET web service. It can also be implement as ASP.NET website but since it has no view (forms, html etc) I planned to implement a web-service.

Security :: Encryption Algorithm - Encryption Of Data Required In The Coding?

Sep 16, 2010

Not sure if I'm posting the question in the right category.

1) I'm working in a project where encryption of data is high priority. Could some one suggest what would be the best encryption method to protect data from being cracked.

I'm using TCP/IP protocol.

2) Is HTTPS totally secured. If I'm using HTTPS, does that mean that there is no encryption of data required in the coding?

Database Encryption Or Application Level Encryption?

Oct 23, 2010

When you need to store sensitive data such as CCs or SSNs, do you:1) Build your own encryption routine within the application, define a secret key somewhere in a config file, and then manually encrypt/decrypt data going to the database.2) Push all the problem to the database, using the built in DB capabilities (I think most vendors call it Transparent Database Encryption).What trade-offs have you find for your solution? Does writing your own routine perform poorly when compared to TDE? Is code maintainability, or conversely DB vendor lock-in an issue?

Web Forms :: Cannot Stream File To Desktop From Pop Up Window

Sep 23, 2010

I changed an app so one of the edit screens opens as a pop-up window via showModalDialog. Previously everything was done in the same window and more back and forth navigation was required. The pop-up provides greater continuity. Unfortunately, as a pop-up, files will not stream to the desktop. If I bring up the page by entering a URL on the address line, so it is not a pop-up, files stream to the desktop OK.

Streaming a file to the desktop is done as follows:

[Code]....

This causes an open/save/cancel dialog to appear in the browser. Does anyone have an idea why a file cannot be streamed to a pop-up window? To get pop-ups to work I always include

[Code]....

in the header. That way I can open other pop-ups such as warnings and database error messages from a prvious pop-up.

ASMX Service Works On Development Server Returns 404 When Deployed To IIS 7.5?

Mar 24, 2011

I have a web application in ASP.NET 4.0. I've added an asmx service, primarily as a source for the autocomplete extender's lookup values.

When I debug on my machine locally, everything works fine. However, when I deploy the web application to IIS 7.5, I get a HTTP 404 response when trying to send data to the service.

I am able to browse to the service definition, see the available operations. Tellingly, however, when I use the test pages to test the service using POST, I receive an HTTP 404 again.

I'm not sure what is going on. I did create the asmx file within my web application and it is deployed in the virtual directory of my otherwise working production application. Is there an issue with the .asmx file being deployed in the same virtual directory, perhaps?

Implement Generic Web Service API

Feb 10, 2010

What is the best way to implement a open/cross platform web service API to an existing .NET App? Not being a strictly .NET friendly API. It already has ASP.NET exposed web services, but need to be built into an generic API allowing inserts, updates and deletes and returning results based on user criteria in standard SOAP, JSON or other common formats, similar to Google's Data API's. Are there any frameworks designed for this or is it a build it from scratch project implementing each format/protocol manually?

How To Implement A Windows Service To Manage Session State

Jul 19, 2010

I'm working on an ASP.NET MVC web application that will be deployed across multiple load-balanced servers. With this setup, a user might have one request served by server A and the next request will be served by ServerB or ServerC. We don't want to store Session Data in the database, as we're trying to minimise database hits where ever possible. As such, we need to have the HttpSession managed and stored on another server. My understanding is that this is possible by using a Windows Service that will manage this for me, but I'm unfamiliar with how to implement this. Can somebody point me at some good documentation on how to do this? Or any pitfalls or other points to take into consideration?
