How can I view mobile users of my ASP.NET Web application just like Facebook chat, and detect their geolocation or their location coordinates

Hi
if you are saying that you have a web application and a user open your web site on a mobile browser - and you want to track that user - then, you can follow the following:
- each request to your page from any browser will have headers associated with them which will tell you which device is the request from.
- you can use this 51degrees api to detect the mobile devices - http://51degrees.codeplex.com/[^]
- once you detect the device - you can perform your business logic
hope this helps.

Not clear. Rephrase your question & update your question with sample example.

If you mean creating a network user account, then you should look at:
System.DirectoryServices
If you are running LDAP you would connect to the Active Directory with something like this ...
_de = New DirectoryEntry("LDAP://OU=xx,DC=yy,DC=yourcompany,DC=com", UserwithAdminRights, password)
Then create a new user from there. You would have to connect to the Active Directory with an account that has sufficient privilege to create users.
Hope this helps.

You have to write the code to do this.
1. You'll want some of way storing what a user's rights are. You could hard code that a principal has the rights but not a good idea.
2. You write code to block anyone without the permission.
You just have to write the code. There is no magic copy/paste code to do this.

this sounds like a question about implementing asp.net membership / roles
in which case you can control access to functions by using membership / roles like this:
if (Roles.IsUserInRole(userName, role)){ //do your role specific stuff here}

In a small company, I am making small changes to a vb.net web forms 2010 application. There are no pervious directions on how to set up the deployment of the application. I have used the old version of deployment using msi packages that are not supported after asp.net 2010. I have not used web deployment yet. I set attached to this application that there is a web deployment project that was used.
Thus can you give me directions and/or point me to a url that will tell me how to setup a web deployment project that can be installed on an IIS server.

I don't think anybody uses web deployment any more, but I haven't taken a poll on the question.
That was a Server 2003 Thing, and IIS6 using meta compatibility or something. I don't remember anymore, but it was another one of those Microsoft things in which they tried to make ASP.NET / Server 2003 look more appealing by offering the deployment program, and then phased it out later on down the road.
I used it back in 2004/2007, then phased it out in 2008 when server 2008 was released. That was 6 years ago.
Speaking of IIS servers, IIS has come a long ways since IIS 5.5 and 6.0
Setting up a web site using web deployment on server 2008+ is a huge security risk.
Times have changed, server 2012 using hyper-visors and virtual servers are the in thing today.
Just copy the folder to the web server, and use the IIS Management console to setup a test website, and play around with it. Don't forget to set your folder permissions for the application pool user, set your bindings and you should be OK. If you need to write to the drive, set the trust level.

DISCLOSURE: I am not a web developer, but I've heard a lot of buzz words about web development
I have a client with small data needs for some very confidential information for his clients, which number around 3,500. For the past 20 years we have done everything on a small server located on-premises, to which only a handful of people have access. Much of the information we have been getting and storing has come from paper forms the clients complete and send in by snail mail, whereupon the data is keyed in to our WPF-based/SQL Server-backed system.
Times change and we now find it necessary to give his clients access to their own information via the web. They'll also be expected to provide updates via the web, rather than the paper forms of old. My client is paranoid about public web hosting and the thought of letting his data go off-site, but DOES NOT have the ability and/or resources to administer a web site locally on his own server.
So, down to the questions:
How feasible is it to use a public host for a web site to handle all the login/authorization stuff, and have that site retrieve the data from, and update the data on, our on-premises server?
How does one manage the tasks of 1) setting up several thousand users with secure login credentials, and 2) managing account lockouts/forgotten passwords/etc.?
What technologies would you advise using? ASP.Net & Azure, for example? What about SharePoint? Non-MS technologies?
What important questions am I not asking here?
Perhaps the biggest question: What important questions do I need to ask my client?
Thanks

My 2 cents here,
Your going to need a couple of decent web servers like a Dell T110 II to design your system on, build your web app and test it. There pretty cheap to acquire, and have nice speed, but it is up to date for current OS and supports virtualization and AES Encryption for SSL. Or one heck of a workstation like a 6 core Xeon to develop on, and build your virtual machines.
We have test servers in house that we spent months on for the design. We created a design in which we can just copy the stuff to a Public Web Hosting facility that supports our design.
So we went with server 2012 standard, created a hyper-visor server core, and created 3 virtual machines using server core, no GUI and partial GUI. One virtual runs the database server, the other the web server, and a backup server.
You can use VMWare in which I like, or the stock Hyper-V virtual machines. Once you dial in your virtual machine, you can copy the machine like a file copy, and upload the machine to a public web hosting facility.
So for the Public Hosting, we choose our internet provider, that has facilities in Las Vegas and Texas, in which they run blade servers with Hyper-V or VMWare. So we get a firewall, a blade server, and access to let's say 6 virtual machines that we can upload. So we upload and download virtual machines, back them up every couple of hours using something like Veeam, and can restore them in minutes if needed.
Regardless of what technology you choose, I think this is the way to go for 2014 and is the current way of the future.
I'm not that worried about being hacked by the neighbor, because you can really fine tune the firewall in server 2012, and limit access to domain members only.

Thanks for taking the time to explain your design and thought process. What isn't clear to me is whether you're putting the db server on the public host or keeping that local. If local, how responsive is you overall set up?
Also, how did you, or how would you, manage the tasks of setting up and administering all the logins?
|
|
|
|
|
Oh its on the public host.
The difference is that because your control the virtual servers, you can narrow the scope of conversation between the virtual web server and virtual database server by fine tuning the firewalls in the OS. You just run all the virtual servers on 1 or 2 physical boxes.

Don't take this the wrong way as I mean no offence, but my advice is that you either find someone who knows what they are doing and sub-contract this out yourself to them, or advise your client do so directly. If their data is sensitive and confidential then you are asking for trouble (for yourself and your client) by taking on this task without already having the appropriate skills.
|
|
|
|
|
No offense taken. It's obvious to me that this task requires knowledge and skills that I don't have. However, my ignorance is vast and I need to get SOME education about recommended approaches to this problem so that I can help my client get the appropriate help.

OK - well, what you/they want to achieve is perfectly possible. However, I'd be wary about anyone telling what is the "best" approach. There are dozens of technologies and approaches one could take. and the best one for any developer is that with which he or she is most familiar! Just one technical point: if you want to keep the database in the office, rather than host it elsewhere, you should ensure that both the web application and the office database have their own unique IP addresses - this will enable you (or your developer) to set firewall and database access rules that will greatly enhance the system's security.

I need to create a chat application (Audio & Video), where chat room and users to be called from Sqlserver.
I went through XSocket.Net,SignalR, and Silverlight each one has their own pro's and con's, could some one suggest which technology will help us to link chat with Sqlserver and do Text, Audio and Video chat.

You'll need to evaluate which technology allows you to do everything you need to do and then if there is more than one still left I would suggest you go with whatever technology you are more familiar with. If you still can't narrow it down start researching them online and looking at what other people are doing with them.
In the end, you just have to pick what works best for you.

Hi All,
I'm using wkhtmltopdf.exe to convert HTML page to PDF. It is working fine when I run from solution and not working after hosting in IIS 7.5. I tried giving all permissions to that folder and tried with changing AppPoolIdentity but still not succeeded  . Please can anyone help me to resolve the issue.
Below is the code that I'm using to convert html to pdf.
protected string WKHtmlToPdf(string Url)
{
try
{
var p = new Process();
string footerURL = ConfigurationManager.AppSettings["Footer"];
string fileName = "TestReport.pdf";
string switches = "-q -n";
switches += "--print-media-type ";
switches += "--margin-top 15mm --margin-bottom 15mm --margin-right 15mm --margin-left 15mm ";
switches += "--page--size A4";
switches += "--redirect-delay 100";
switches += " --orientation Landscape " + Url + " --footer-html " + footerURL + " " + fileName + "";
var startInfo = new ProcessStartInfo
{
FileName = Server.MapPath("~\\Utilities\\wkhtmltopdf.exe"),
Arguments = " --orientation Portrait " + Url + " --footer-html " + footerURL + " " + fileName,
UseShellExecute = false,
RedirectStandardOutput = true,
RedirectStandardError = true,
RedirectStandardInput = true,
WorkingDirectory = Server.MapPath("~\\Html")
};
p.StartInfo = startInfo;
p.Start();
p.WaitForExit(60000);
int returnCode1 = 0;
try
{
returnCode1 = p.ExitCode;
}
catch (InvalidOperationException)
{
}
p.Close();
return (returnCode1 == 0) ? fileName : null;
}
catch(Exception ex){
throw ex;
}
}
Thanks & Regards

Try two things (separately!):
1. run wkhtmltopdf from command-line
2. move wkhtmltopdf to bin folder of your site
I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is. (V)

are you running in on a server core with no gui?
you need the minimum gui to run shell command apps in the cmd window, or else it executes and never does anything.
