I am looking for a tutorial or more information on creating a Templating system to allow a user to edit the template of a ASP.Net website, Such as creating his or her own 'Skin'.point me in the right direction.
I am working at a site not orginally devleoped by me. The problem is that all the pages are working fine and have no problem at my local site. but the site is not showing any content at live site from database. Niether it shows an error for it. How can I find the problem?
I'm about to begin designing the architecture of a personal project that has the following characteristics:
Essentially a "game" containing several concurrent users based on a sport. Matches in this sport are simulated on a regular basis and their results stored in a database. Users can view the details of a simulated match "live" when it is occurring as well as see results after they have occurred. I developed a similar web application with a much smaller scope as the previous iteration of this project. In that case, however, I chose to go with SQLite as my DB provider since I also had a redistributable desktop application that could be used to manually simulate matches (and in fact that ran as a standalone simulator outside of the web application). My constraints have now shifted to be only a web application, so I don't have to worry about this additional level of complexity.
My main problem with my previous implementation was handling concurrent requests. I made the mistake of using one database (which was represented by a single file on disk) to power both the simulation aspect (which ran in a separate process on the server) and the web application. Hence, when users were accessing the website concurrently with a live simulation happening, there were all sorts of database access issues since it was getting locked by one process. I fixed this by implementing a cross-process mutex on database operations but this drastically slowed down the performance of the website. The tools I will be using are:
ASP.NET for the web application. SQL Server 2008 R2 for the database. probably with an NHibernate layer for object relational mapping. My question is, how do I design this so I will achieve optimal efficiency as well as concurrent access? Obviously shifting to an actual DB server from a file will have it's positives, but do I need to have two redundant servers--one for the simulation process and one for the web server process?
I will shortly be going live with a new .net web application. It will be deployed to a load balanced environment over 5 servers.Before go live there is a holding site on all the 5 servers to which the domain is currently pointing ->Prior to go live, I would like to deploy the new site to 5 servers and for the holding site to remain and for it to be what the public sees. And when the time comes, I can put the new site live with a flick of a switch. I also want the new site to be on the servers so that I can test it prior to go live.I am running in IIS7. This is common practice I presume so what is the easiest way doing that above and achieve installing the new site on the servers will not affecting the holding site. The new site be accessible to me but the holding site be viewed by the general public.
After going through few asp.net 2.0 books surfacially, I want to accomplish most of the task using c# code and Sql database.
1.we can access and update data using various ways like using sqldatasource code, data reader,command object,dataset,datatable etc.But which one to use in which situation?I am very confused.what do you prefer most,why?
2. How to code professional way? I mean how to separate code using different classes and how to link all togerther?
3.I want to design a webform for entering/editing user input using c# code and use presentation control like gridview and detailsview for viewing,paging and sorting only.Is this possible?
Is it OK to use css optimizers to before to make site live. When we can't to any other server side compression techniques (gzip, combining, sass, less etc)I want to make CSS file short and readable. How to use these tools without loosing css functionality. what options we should use and what not.
I've got a really good idea for a service I'd like to create for the web, but since I'm new to ASP.NET I'd like to get everything up and running before I go and buy hosting etc.
What I'm curious about is the database side of things.
I don't quite understand how I can create a datebase on my computer for the sake of testing and practicing (Presumably through mssql server) and then just transfer it to a hosting account when I'm ready.
I guess the main part I don't understand is how can I connect to a database on my computer via my application and then change the connection so that it points to the web version when I'm ready.
I know that when you create the database and include it in your project it's not technically inside your project (Right?), but it just seems that the application is very rigid once you've specified the connection.
I have a intranet site with Windows Authentication. I have 'Administrator' pages in an 'Administrator' folder that will only show for those in the admin group (windows security group) These pages work
I have a folder with sub folders containing reports. These permissions are broken down for each type of report. They have similar role priveleges. When I test the application, I can navigate to the pages. When I deploy the site live on the intranet the links don't return a page. Error missing link 404. Do I need to set something in IIS?
Thing is, if I run this locally and drop my internet connection the web service returns a 500 error (like I want it to do) and deleteCustomer(customer.id); is not called. However, on the live site if I drop my connection the web service does not return an error and deleteCustomer(customer.id); is called even if I don't have a connection to the internet (customer gets deleted from local database without being posted to the web server).
I want to include Microsoft AntiXss V1.5 library on my live site running in a medium trust setting.However, I got an error something like:Required permissions cannot be acquired.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Security.Policy.PolicyException: Required permissions cannot be acquired.I tried this in full trust setting on my development machine and everything works good.Looks like this will run only in full trust configuration.
when a user enters a bad email I am doing a check on this and throwing an exception message as follows, this works fine on the test site but for some reason the same code on the live site gives a "internal server error" (http code 500). The code below:
This is my third site that I use role management, but the first time this happens. I have two roles: Member and Admin. If Admin user login, Admin node on sitemap shows. It works very well on my local machine in Visual Studio Express 2008 and in Visual Studio Team 2008. But once I deploy files to live site, even admin login, the Admin node doesn't show. I have a Member management page from which I may see member's role, and I can see that user name is in the role Admin. What could be wrong?
I used ASP.Net Configuration manager to create roles, users, and access roles. Here is the code:

I'm trying to figure out a logical and quick way to implement the "PRG" design style in a small site I'm doing, and I'm finding an issue I can't think of a good way to solve.I have a form. It has 2 fields (first and last name). When the user submits the form, I check to make sure that they have data in them before I save it to the database. If they do not, then I show them a nice little error message and leave what little they have entered still in the form.However, in order to correctly implement PRG, as I understand it
So i was thinking on using an image and a literal control. The questions i have is
1)Is there a better control to use than literal?I am using it because the text would have html and i must render it.
2)How i will achieve putting text beside the picture(the site uses a <strong> as i see in firebug but i cannot view the css and after that everything is simple text and some <br> )?
If i put the literal beside with <strong> and have a specific div size will the text automatically go below when reach the div limit?I'm asking because it will be html so i don't know if it(html) can surpass the main div container.
I have a web app with a table of statistics on our salesmen's customers, and each row has a sparkline graph showing the general trend of the sales data for the last 12 months. Each page shows a particular salesman's customer list, and some of them can have an enormous number of customers = an enormous number of rows = an enormous number of sparklines (e.g. one in particular has 125 and takes 15 seconds to load).
For this reason, jQuery sparklines could not be used - they completely pinned the CPU of a user accessing a page with a lot of sparklines with IE.
So I moved on to using the Google Chart API, which worked much better, except for two issues: 1) it's on a secure site, and the Google Chart API URL is only served over HTTP (solved by using a small wrapper script to download the graph dynamically and re-serve it from our secure server); and 2) on a page with 125 sparklines, it was still very slow due to the number of requests (even when the 0-9 server prefixes are used to maximize the # of available connections).
So my next step beyond this was to try to make each of the "download/grab/re-serve image" method calls asynchronous - and it worked!
...but only on my dev box running in debug mode.
When I pushed it up to the live site, it was faster, but it left some of the images unloaded, which is of course unacceptable.
So here is what I was hoping some SO hotshot would know:
1) Why are my asynchronous method calls working while debugging, but not working on the live site?
2) Is there any easier way to get a large number of sparklines of some sort to load quickly on a secure server without making me want to tear my hair out?
2a.) Does anyone have any experience using the ASP.NET Chart Library? Is this something I should investigate?
2b.) A co-worker suggested I make my own sparkline routine using a 1x1 CSS background image and varying the height. The problems are a) it is completely un-extensible in case we want to make changes; b) it seems hacky as hell (leaves about a bajillion DIVs per sparkline in the markup); and c) I have no idea if it will be fast enough when there are 100-200 of them on one page - what are your thoughts on the feasibility of the 1x1 sprite approach?
Live Chat is a very famous tool on websites, and the operators use a special web/windows interface to talk to the clients.What I want to implement is to specify some email accounts, and when the client click's the live chat and starts typing, his/her instant messages are delivered to the available email account. My operators can talk back to them as if they are on their friends list.I don't need to require any login or registration for clients to use this Live Chat.So are there any ideas about how to implement such a thing? Are there any good third-party-modules that already do that?
I am using a generic handler (indicator.ashx) to create a graphic that is overlayed from information from a table (called LIVE) from our SQL database. This is working very well and I am very happy with the results.
However I am having an undesirable issue where the query string that is used for this is also being accessed by another page (called ReceiveLive.aspx) which is populating our LIVE table with data when we don't want this. I have been able to track this issue down to our generic handler that seems to populate this table with data whenever the handler is accessed.
The query string that is used to access our graphic through our generic handler is http://mydomain.com/indicator.ashx?ID=ABC001.
Our other page that writes data to our LIVE database used the query string http://mydomain.com/live.aspx?ID=ABC001 which is normally only accessed by a small piece of software that sits on the users PC and sends the data when necessary.
My question is this: How do I prevent data from being written to our LIVE table via the Live.aspx page everytime a query string is processed by my indicator.ashx is accessed?
