Detecting Web Browsers' Versions?
Dec 19, 2010
i'm programming an application where an action is done if i access with a version equal or higher than other and another action if i access with a lower version; but the problem is that the lines to indicate the versions doesn´t work. The code is the following:
[Code]....
As you can see, an action should be done if the version is the 9.0 or higher and other if it is lower, but these lines doesn't work and only works the detection of the web browsers (no the versions of them, action that doesn't works).

So I'd like to redirect mobile users to a different page. But instead of trying to detect any number of mobile browsers, I'd just like to see if the user is using IE, Firefox, Safari, Chrome, or Opera; all other users go to the mobile site. My biggest problem is detecting regular Safari from mobile Safari.

I have an existing web site and I would like to create a mobile version of it that is more suitable. For instance, the main site uses drop-down menus and we all know those are quite the fail on mobile devices.I would like to redirect to my mobile version (it will be a subdomain of the current site) if I detect a request from a mobile browser. So when they Google something and come to my site, they will automatically see the mobile version (just like Wikipedia).Does ASP.NET provide an easy way of doing this

My LogIn action originally looked like this:
return new RedirectResult(nameValueCollection["ReturnUrl"]);
But, I would like to know whether the client has JavaScript enabled before the home page loads, so I changed it to this:
return View(new LogInViewModel { ReturnUrl = nameValueCollection["ReturnUrl"] });
And send the following view instead of the instant-redirect:
@model Obr.Web.Models.LogInViewModel
@{
Layout = null;
string noJSReturnUrl = Model.ReturnUrl + (Model.ReturnUrl.Contains("?") ? "&" : "?") + "noJS=true";
}
<!doctype html>
<html>
<head>
<title>Loggin in...</title>
<meta http-equiv="REFRESH" content="1;url=@noJSReturnUrl">
<script type="text/javascript">
window.location = "@Model.ReturnUrl";
</script>
</head>
<body>
<noscript>
Loggin in...<br />
<a href="@noJSReturnUrl">Click here if you are not redirected promptly.</a>
</noscript>
</body>
</html>
The idea is that if the user does not have JavaScript enabled, they see a brief loading message, and the home page loads after a second. If JavaScript is enabled, the page reloads instantly. In the future I could even post to the server the dimensions of the viewport and such. Does this look like it would work? If the window.location command takes longer than a second to run, will it be interrupted by the meta refresh, or does it block that refresh? I am hoping the latter, so I don't need to increase the delay for those non-js people.
I figure my new way adds a little extra weight to the payload of the redirect, but it's not an extra round-trip or anything, is it? The redirect happens anyway, does it not? Update: I neglected to mention a very important point. I do not actually have control over the login screen itself, only the page it posts to. This code is part of a product that relies on an external authentication mechanism.

I maintain a web application that is painful to upgrade. It's not painful because the code is bad, but because there are a lot of devices connected to this application via the web and getting them to update their clients is a lot like moving concrete.
So I had an idea that I could simply present a different version of the application to different customers. The session stores the client information. So what I'd ultimately like to do is peak at that session and then use that to present the "correct" version of my app to them.
Physically the apps are stored in a manner like such:
C:Program FilesCompanyProgramVersionWebWebApp
So you can see that I could have multiple versions installed at once. Basically if customer A goes to the site they get presented with C:Program FilesCompanyProgram1.0.0.0WebWebAppfoo.aspx And if customer B visits the site, they get to see C:Program FilesCompanyProgram2.0.0.0WebWebAppfoo.aspx.
I initially thought of using the IIS rewrite module, but I really don't want to redirect them. I want this to be seamless. how this can be implemented?
update:
After further research, I thought it would be clever to use the Global.asax.cs to accomplish my goal. So in the Application_BeginRequest event handler, I wrote the following:
[code]...
By the way, /art/ is a virtual directory that I grafted into this directory via IIS. This would be similar to how I would set it up in production. Anyway, I get the following error when I try this.
The virtual path '/art/test.html' maps to another application, which is not allowed.
So how do I do this then? Is there an "allowed" strategy for accomplishing this? Doing it through the Global.asax.cs would be ideal since I could use the HTTP Context to "know" which customer is connecting to the app.

I have an asp.net mvc2 project that will be deployed on several servers. Some may run on IIS6, IIS7 (Classic), or IIS7 (Integrated).read this article on how to deploy to these servers, but I was wondering if my routing can be set up in such a way that it can handle any version of IIS. That way, I only need to use the same routing in my global.asax. This is my routing right now.
[Code]....
I decided to use the option of handling the aspx extension so I don't need to do anything anymore to the IIS settings. Unfortunately, I can't test it right now because my IIS isn't functioning right (dunno why). So, I'd really appreciate some help on this one.

My new assignment at work is to create a second version of our existing web application. Currently, our application supports only full time brokers, but now we our launching a second site specifically for part time brokers.
The new site will be almost identical to our existing site with the following exceptions:
It will have it's own branding. A couple of the user controls used for displaying information will be different (but none of the pages will be different). Our existing users should not have access to the new site and vice versa. It needs to be easy to test both versions of the website from within Visual Studio easily. We want to reuse as much our existing code as possible. I have 2 weeks to do this. I'm hoping that this is a common scenario and someone out there has some advice for how to accomplish this.

I'm developing an extra section to a web app that's written in asp.net, but in php - it's mostly done (the two parts don't really communicate with each other outside of a database - the integration is mostly just cosmetic.)
The only issue I have is detecting from the php part when the .net session has expired so that it logs the user out and redirects to the login page.
I believe the asp.net application is compiled, but either way I'm not allowed to alter it so I was thinking maybe the best thing to do would be to make a very small/simple aspx page that outputs true or false which I could call using curl from php (and passing the browser's cookies along.)
Would this even be possible? I'm not sure how session security works on asp.net eg whether one .net application can read another's session variables, but if it's anything like php then it'll be possible.
mypage.php --curl--> checksession.aspx --|
| |
<----------- true / false <---------------
So mypage issues a GET (with cookies from browser) to checksession using curl, checksession simply returns a true or false (or something like that) and mypage redirects to the site's login page if that's false.
The authentication for the php side is already sorted out and is separate to this issue.
So really, what I need to know is can I have just a simple .aspx file that does this check, and if so where would I go to to find out how to program such a simple page?

Is there a way to detect if the user closes the browser/popup page? I am trying to implement a chat functionality by when the user closes the browser/page, I will update the flag in the database from active to not active. But I cannot seem to find a better way to handle that besides from detecting if the user closes the page.

I'm working on an ASP.NET web application. There's a bill page which has two links to different pdfs of the same bill. When you click on one of the links it takes you to a ViewPDF.aspx page that shows the pdf. There's also an option to view both in a split screen so that you can compare them. When you click on this link it takes you to BillSplit.aspx which has a frameset and two frames that both point to ViewPDF.aspx. This all works perfectly.
The problem is that if an error occurs while pulling up the pdf. The application has an error page that has a few links back into the application. If you use one of these you can go back into the app and continue but now inside the frame. The URL still says BillSplit.aspx but the application is completely unaware of this since frames are HTML elements not asp.net controls.
What I would like to do at this point is detect that you've returned to the application and close the frame you aren't using. Essentially I'd like to redirect you away from BillSplit.aspx and to the page you're actually requesting. I'm pretty sure this would need to be done in Javascript either on the BillSplit page or on the pages that you go to later. So I guess what I'm asking is, is there a way to ensure that the BillSplit.aspx page and it's two frames point only at ViewPDF.aspx?

I built an assembly, and that assembly refereces a DLL in my bin folder (lets call it Bob.dll). so multiple users may have different versions of Bob.dll...but by and large they all function the same.
However when my assembly gets dumped into the bin folder, it wants the version it was compiled against.
Is there a way to compile a reference such that it'll just be happy with ANY version?
I know it can be done with assembly binding in the webconfig, but I dont want users to have to do that.

My web page is still displaying a previously cached versions of the page. I have this in the page_load event:
Response.Clear();
Response.Buffer = true;
Response.ExpiresAbsolute = DateTime.Now.AddDays(-1d);
Response.Expires = -1;
Response.CacheControl = "no-cache";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
I have this in the Page_Init:
protected void Page_Init(object Sender, EventArgs e)
{
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetExpires(DateTime.Now.AddDays(-1));

I'm working with an MVC2 app that had migrated from an MVC1 app quite a while ago. Things have been working - i've been able to compile and deploy a number of iterations without any problems ..
I've noticed that the version info - that bit in the footer of runtime errors - i've received during the normal course of development reads:
Version Information: Microsoft .NET Framework Version:2.0.50727.4952; ASP.NET Version:2.0.50727.4955 despite the fact that the project's Properties | Application tab shows the target framework to be .net 3.5. I _think 3.5 is required for mvc2 apps, isn't it?
Shouldn't I expect to see runtime error pages pointing to version info at the 3.5 version?
UPDATE: As that this isn't a simple matter of a framework mismatch, here's the error - but given other factors, I'll assume I need to repair/refresh the workstation's framework installs. The same code works on another ws.

I have an ASP.Net web site (ASPX and ASMX pages) with a single web.config file. We have a development version and a production version. Over time, the web.config files for development and production have diverged substantially. What is the best practice for keeping both versions of web.config in source control (we use Tortoise SVN but I don't think that matters)?
It seems like I could add the production web.config file with a name like "web.config.prod", and then when we turnover all the files we would just add the step of deleting the existing web.config and renaming web.config.prod to web.config. This seems hackish, although I'm sure it would work. Is there not some mechanism for dealing with this built in to Visual Studio? It seems like this would be a common issue, but I haven't found any questions (with answers) about this.

I am setting up a new website on new web servers that are running IIS 7.5, which is new to me. I have ran into a problem when deploying an ASP.NET app that is using the 4.0 framework. I get error messages about conflicts with the web.config file associated with the Default Web Site. The asp.net app defined in the default website is using the 2.0 framework currently. My 4.0 framework app is defined as an application under the default website. Both are using different Application Pools. I tried adding this to my 4.0 apps config file
<location path="." inheritInChildApplications="false">
How do I get around this web.config conflict issue? Update for error message: There is a duplicate 'system.web.extensions/scripting/scriptResourceHandler' section defined. The config file for the 4.0 app does not even have this section. The default website app does have this.

I recently started using fusioncharts (which is a great charting tool btw) but I releaized that although it renders Right to Left languages correctly, it does not display them from Right to Left, so if I have "Sales Report" in Arabic, it will be displayed "Report Sales" in the chart.
I dont have a problem with this with static text because I can reverse it before I send it to the chart, but with dynamic text that is entered by the user it is a challenge, because the user may enter the details in English or in Arabic, or in both.
So if I can define the character code used in the sentence then my problem will be solved, and the first thing that came to my mind in order to do this is:
- Take one letter from each word in the string and compare it with the Arabic alphabet (instr function).
- If the function returns true then the letter will be arabic and therefore the whole word will be arabic, I'll store this word in a new string
- If the next word is also Arabic I'll add it to the new string else I will skip it and start a new string for the next words to come.
- After I finish searching the string I will reverse the words in the new string and replace them with their parts in the old string then send them to the chart.

I have a single project website and I would like to create different versions of it to be hosted on different web servers. I do not know if I need to have different versions of the web pages placed in different projects within a single solution or if I need to put different versions in a single project within multiple solutions. I need to be able to build and publish each version separately as an independent website for uploading into a different server. What should I do?

We are looking to create a website that displays information to all new visitors to a site, i.e. welcome,The big problem is that our website is not allowed to use long-lasting cookies (i.e. over 20 minutes). Does anybody know of any way we can determine whether a user has visited the site before or not. As another restriction, we can not add anyform of registration to the system. The application is being created in ASP.Net 3.5.

I have a web site which uses forms authentication and we have a log out page which will sign out the user and set that they are signed out in the database. This needs to be done as they use concurrent licences. The problem is that users are closing down the browers without logging out, meaning that the database shows them as logged in. I would use javascript onbeforeunload/unload functions to call a webservice, but this is unreliable to actually know if they have closed down the browser. or just hit refresh. An idea i had was to have a web service fired every 20 mins to detect if a user has loaded any pages within 20 mins, if they have not then to set them as logged out.

As per the requirement of my client I would like to create an application which detects content changes on the websites we provide. Like we will have an admin section where we add the websites we want to keep a track of. And on the other side it tell us of any new content on those websites. The websites will be kind of general news website and won't have RSS feeds. I would like to know if there is any way to do something like this. Any ideas are welcome. I would like to know just the logic how to create such a thing.
