Hello,
I do apologize if this is the incorrect forum to post.
I have a file which I need to post to a remote client server. I created a .p12 key file from the client web site. Using this .p12 ket file, password information I need to post a file to the server.
Using class, X509Certificate2 from namespace using System.Security.Cryptography.X509Certificates X509Certificate2.
I created a simple C# console application on my laptop using VS 2010, to define the parameters to the .p12 key file, and path to the csv file to post to remote server. I keep getting "Remote Server returned error - 401 UnAuthorized Error". Is there some sort of permission issue on .net end or the client side. The client keeps stating there is no communcation problem on their end.
I have been working on this code for some time now. any ideas is much, much appreciated.

To me, based on above statements, it looks like the request is not going through. The key created/used is not having correct password or so leading to unauthorized error.
Issue wise, it might be of certificate or the way you are sending/using it to communicate. Ideally, client server must be setup to accept calls with proper certificate(having correct password) for handshake permission. Error wise, the communication is not as per expected. Talk to someone on client side, make sure you are communicating correctly and the certificate-password is valid.

We have tired of ton JS code in our applications, when errors could occurred in runtime (and specific browsers only).
So we decide to write something which allow to build rich client-side (single page as well) web applications on C# using our Incoding Meta Language.
It's simple - you define the tag behaviour on C# and then it parsed using our JS engine. Any js library could be plugged in, like we did for the Jquery UI (dialog, slider), Google Maps (show map, add/remove marker), BlockUI...
Even more, some our new developers even don't know the Javascript at all now 
No trial, no donate. Just Open Source. We would like if someone would say "that's cool, i will try!" and give any feedback (critics are welcome).
I know some questions would be like "we need to learn this before start using, why do we need that if we already known js?".
- I would answer by asking another thing:
"What if your teammate (or another developer) leave some code for you and you need to understand what the hell this js construction is and first of all, where to find that event handler?"
With this approach, you just find the element on page and see what the behavior defined in C# well typed code.
You may kick me for the spam, but I just want to discuss:
1) If this type of approach could be alive or not?
2) What are your suggestions? Do you use something else to exclude such problems like we have had to write this?
P.S. We have all current projects using this. And there are server-side features as well.

How can i go about maintaining the state of an intranet application: Such that an authenticated user can process one or more sales in an instance?
On the otherhand is it possible to assign a Session object a value that is returned from a process after the Application had already started and running?

And the issue with it? You can use Session variable to keep track of the current authenticated user and use that for multiple calls.

Not sure what application you are talking of here. If you are talking of your web application, then yes, sessions can be defined and assigned values later in the workflow as and when required.
Sounds like state management article should help you.
Depending on the requirement/security/performance/UI implementation, there can be various ways to pass on data from one page to other.
You can use Querystring, Session, PreviousPage, etc.
Have a read on the following:

I would suggest you to start you Asp.net Journy with MSDN : ASP.NET[^]. You can also check this[^].
See a video article on Choosing the Right Programming Model[^].
All the best. 
--AmitI wish, I could have written for my mind:
Mind.AsEnumerable().Where(m => m["EmptyCorner"] == "").ToList().ForEach(s => s.SetField("EmptyCorner", "C#, Asp.net, Linq, Java, .....Everyting"));

I need to take the main parts of a C# 2008/2010 console application and turn it into a thin client for the web. The only things that need to be displayed on the screen is to enter the customer number and where to obtain a file in a directory path. The user will it the enter button and the application will pass the information to a web service.
Notes about the code that will be used: 1. the application uses linq to sql to point to a sql server 2008 r2 database.all parts of the exisitng code is placed together. there is no separation of data, presentation from business logic.
The simple application will not be part of any other web application.
Can you tell me the following:
1. How will the user start the application? Would it be a url on the web and/or a shortcut on their desktop? How would you setup the code for the user to click on a desktop short and/or point to a url?
2. When you start the code from scratch, what kind of a web application would I use? web forms since that is the easiest.

So your making a windows app to talk to a web service? If your making a windows app, you have to connect to a web service, that is cross domain capable. Then it doesn't matter what connects to it. It would be a ashx page I think, just pure code, no web form or HTML elements in it.
[EDIT]
I don't understand the question, sort of goes around in circles.

I will describe the current C# 2008/2010 application and then I would describe what I would like to do with a 'new version (clone) of the 'second' program.
The current application and that will not be modified does the following:
1. A driver program (C# 2010 desktop/console) calls the 'second' program with parameters it needs for the particular run.
2. The second program calls a web service that is supported by another company to upload and download documents from the web service.
The 'new version (clone) of the 'second' program:
1. The new version of the 'second'program listed above will do the following:
a. A user will access a C# 2010 web form page to enter client number, point to a directory path of where files are located that need to be uploaded to the web service, and click a submit button,
b. The web app will then use the 'existing code' it copies from the progam listed above to load documents to the web service and receive a repsonse fromn the web service.
Does this clarify what I am looking for?

much clearer now, thanks.

Do you have any idea how I should start?

Sorry, I was busy with my project, and some ads I placed, nothing came to me.
If it was me, I would experiment with the final web service first, and prepare or create something to package the data first, to send to the web service, and create something to read the response from the web service. While doing that, I would create a test program in windows, to transmit the data, and read the data returned. Then try something with a web form, and see which works better, or just create both.
Then run them by some testers for feedback.

Hi experts,
I stuck on this error message. can any one give me a hint?
in my code behind(ASP.net C# web form programming), I try to evaluate a session variable, then execute some codes... debug pops this error message(see below) every time when it runs into the session evaluation line. What is proper setting in webconfig to fix this? can u give a complete sample. I tried as message suggested, it still pops.
if (Session["name"] == NULL)
//Do sth
error message
Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the \\ section in the application configuration
Thank you in advance

web.config settings are here[^]
the link is for .net 1.1 because it's easy to read.
start by setting mode="InProc" and see if that helps.
<configuration>
<system.web>
<sessionstate mode="InProc">

Is it possible to display a message in browser console window by coding in code-behind.
I am aware that it could be done by javascript as well as we can set message in Visual studio output window by using System.Diagnostics.Debug.WriteLine() method.
But I am looking for a way to set message in Browser console so that I can have easy access to it without disturbing its normal operation when code is set up on server.

Sir;
I think you can use the code below:
function log(msg){
if (window.console && console.log) {
console.log(msg);
}
else {
document.write(msg);
}
}
note that you can use any member function in console object to control the console messages.
Help people,so poeple can help you.
