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)
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
Is it possible to display a message in browser console window by coding in code-behind.
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.

i tried from manage_pages in facebook,But not sure how to get the list of pages,Please advice me on how to accomplish this.
I use to bind years ago, but overall in the end, the bindings have to be recreated if you move your project to another server or something. And it was so slow, because the binding code has to be created every time it's used.
So you create a function to load the data, and package the data in a class or structure, and loop through the class or structure records. Something like below code, that's just off the top of my head in vb, but you should get the idea.
Public p_StateName asstringPublic p_StateAbbr asstringEndStructurePublicSub load_States()
Dim p_stateCount asInteger = get_StateNames_Count()
Dim sSn(p_stateCount) as structure_States
Dim dwExitCode asInteger = load_StateNames(sSn)
if (0 = dwExitCode) thenFor idx asInteger = 0to sSn.length - 1
ddl_StateNames.Item.add(new ListItem(sSn(idx).p_StateName, sSn(idx).p_stateAbbr))
NextendifendSubPublicFunction load_StateNames(ByRef s_StateNames() as structure_States) AsIntegerDim dwExitCode asInteger = 2'Do Database Read
I have a great opportunity at work to get to learn ASP.NET. One of the project I need to work on is to design a web form for software registration. However, I do not know ASP.NET that well... actually not at all. I was wondering if any of you can recommend either books or web sites that you found that was helpful in learning ASP.NET.
By the way, I am not asking for a Google search of "Asp.net Tutorials" what I am asking is what tutorials have you found helpful in learning ASP.Net.
Not sure if that helps at all but I am using VS2010 and using C# for the behind code.
However, in working with a lot of developers over the years, you don't want to focus on the specifics of ASP.Net, which is just a server-side HTML-generator, essentially. Since it's generating HTML, and the browser only understands HTML, an ASP.Net developer who isn't an EXPERT in HTML is going to have difficulties. So, my suggestion, to become a good ASP.Net developer, is to go learn HTML5/CSS3/JQuery and how to build pages using only that stuff. THEN, you will be competent at programming the ASP.Net server to emit HTML pages.
One of the best tutorial sites on the web is Codecademy - interactive tutorials which run automated tests against your code to check your work. I've done almost all of their tutorials on various languages, and I highly recommend doing their basic web development tutorials, AND the advanced ones about JQuery and you should also pick an API like Parse, and learn that too. This will give you a holistic view of current web programming languages, and a simple introduction to all of them.
It's not an error in your code, the user hasn't given that permission to your app. You'll have to log in your Facebook account and it should have a request from your app waiting for you. Only the Facebook user can change this option - your app can't change it.
I'm starting a side project, the first stage will be a building a web application with MVC, in later stages we will be adding clients for mobile platforms. My thought was to create one API that all of the applications (web and mobile) go through to get/save data.
Because these different platforms will be on different release cycles I'll need a way for, say IPhone, to work with one version of the API while the website is using an updated version. What's the best way to do that? Can someone point me to a nice article or blog post somewhere about that?
My ideas so far are:
*Create a separate project to host the MVC Web API and host that in a subdomain or in a subfolder of the root site. Then either reference the DLL directly or reference it through the web (seems like an unnecessary http call)
*House the API withing the MVC project that will be the website and try to version it based on url in there. I did some quick testing with that this morning and wasn't able to get it to work, it always resided at \api (I couldn't get it to reside at \api_v2)
Any ideas or guidance would be greatly appreciated.
