MVC :: Comparison Against Other Programming Environments Or Techniques?
Jan 28, 2010
what MVC stands for,but if I'm already developing .NET websites without it,is there any reason I would need/want to use it?is it designed for people who already have experience with developing in an MVC environment and wanted a ".net"version of it?Is there some "head-to-head" comparison of MVC against other programming environments or techniques that have been written? It seems like what I might gain in development speed I might lose in flexibility.maybe I just don't understand what all the fuss is about.hence this post!
but I am rather confused about what to invest in. I heard that server-side code translates into client-side code. So, if you have an .aspx file, it will be converted to HTML/CSS/JavaScript. I have experience with the latter three technologies put into a rather dull text file and rendered by a web browser. My question is how much HTML/CSS/Javascript coding would I have to do when server-side programming? In other words, can someone using ASP.NET program purely on the server side and not bother to write for the client side? Of course, I don't care about server-side being translated into client-side, but I am wondering if client-side programming needs to be done explicitly and to what degree.
Scenario: I have a complex Asp.net app serving various units through programmatically constructed control collections in HttpModules. Some of these controls use Asp.NET Ajax.
Across many different units, ScriptResource.axd averages a transfer size of ~27k.
I have a ceiling that only allows ~3k for it.
There definitely isn't time to retrofit all the Ajax functionality with jQuery or hand-rolled js functions or whatnot. We already have the .axd coming over with gzip encoding (uncompressed it's more like 97k). It's often cached, but that doesn't matter: I have to hit a hard, low, externally-imposed limit on first-request total transfer size... markup, scripts, images & all summed up a-la firebug. I've been avoiding the .axds, but there really isn't anywhere else to shave bytes, and I have 24k to go.
Possible approaches: I'm not yet using Asp.NET 3.5 SP1's compositescript functionality, but I figure that would only save on request/response headers, and I'm not even sure headers count against me.
I don't have any other ideas other than something radical, like creating a response filter that uses reflection & some dictionaries to figure out what js functions are actually needed, and only emit those. I could cache the resulting list for each unit, since I have a low response time ceiling as well, and I don't think the .axds change from one request to another. Is this feasible? Any other ideas? ...what if I buy beer for the hero with a solution?
I have created an ASP.NET website which accesses a DB. The DB can will be alrady installed at target machine. It can be anything from SQL server 2000 to SQL server 2008. Further more the target OS can be anything from Windows server 2000 to Windows 7. I have kept the target .Net framework version as .Net 2.0 to keep matters simple. Also, the target machine can be x86 or x64 or Itanium. Do I need to create separate builds for different target platforms? How do I create an Installer which will : Put this website on a Virtual Directory of IIS server(can be any IIS version) Detect the target platform and install the appropriate build. I need to do this either using the standard MSI installer of VS2008 or using WiX or any open source installer for that matter.
I am trying to load test a web application, but I am having a hard time finding good tools that are affordable. I cam across Web Performance Load Testing Tool which is pretty cool, but limits you to 10 users and after that it costs thousands. any good techniques for load testing a web application?
This question is for ASP.NET and SQL Server developers. What are your best practices with respect to setting up your development and test environment? I'm interesting in the following issues:
1. How many tiers do you recommend and what goes on on each tier? Just dev, test, and production or perhaps dev, test, staging, and production?
2. Which types of applications and/or servers should run on actual physical hardware and which can get away with a VM?
3. What are your strategies for loosely coupling users from web sites, web developers from their web/app/DB servers, and DB developers from their DB servers?
4. How do developers stay "DRY?"
5. What are the pros and cons to putting web, app, and DB servers on their own machines? Does putting servers on separate machines in order to minimize contention for a machine's resources trump any NIC and network latencies that might be introduced by putting them on different machines?
6. How do you configure your web apps to minimize contention for resources (e.g. virtual directories, separate application pools, etc.)
7. How and how often do you refresh your databases on each tier? Do you just refresh the data or both the data and objects?
We deployed our legacy ASP.NET application to production after successful test deployments to our staging environment. The application makes use of RequiredFieldValidators on one particular registration page. On our development and stage environments, the validators successfully detect empty fields when "Submit" is clicked, error messages are displayed, and form submission is prevented. But on production, the validators do not display error messages. Clicking submit will cause a postback, the code-behind checks for Page.IsValid and correctly detects the form has missing fields, but the registration form is redisplayed with no error messages (ie "Please enter an email") to the user.Sample: (note I dont explicitly declare EnableClientScript or SetFocusOnError)
<asp:requiredfieldvalidator id=Requiredfieldvalidator1 runat="server" CssClass="NormalRed" Display="Dynamic" ErrorMessage="Please enter an email." ControlToValidate="txtEmail"></asp:requiredfieldvalidator>
Both environments (stage and production) are identical: Win2K3 Server and IIS 7, SQL Server 2008, and ASP.NET 1.1 runtime (embarrassingly).
What is the best way to store/access connection strings and most importantly the URLs for different environments (dev, validation, production). I'm using ASP.NET 1.1.
I am in the process of building a survey using asp.net and store these results into a database. Now this is what I am trying to achieve: - The survey is fairly long but will be split up in sections. - the way I have been told to develop this is to save each section into the database when the user clicks on a next button for example rather than clicking a final submit button and then submitting the results all in one go to the database. The reason being is for example, the user's browser crashes etc or if they accidentally close it down. I need to build it such a way that survey can remember who the person is.
I can't use windows authentication as it will be externally based, is there anyway I can uniquely identify people when they arrive on the web application e.g. by using a guid? Can it be guaranteed that the person who arrives on the application with a guid on that machine be exactly the same when he/she arrives again?
I have seen the examples on how to switch between connections strings for development and production enviroments. My web.config also calls out a connection string for <roleManager and membership><providers>. Can this be setup to switch between the two connection strings?
I'm currently in the process of creating a library app to use inconjunction with websites. Note: NOT JUST ASP.NET SITES. I say this because i've made the dll available to COM and it works, I can reference it from VB6 and see the types/functions/enums etc...My question though is this: I like using List<type> in c# and I know if this dll was only to be used with .net sites then there would be no issue but how would a List<type> be returned to a different environment. Can they recognize this?
In my project i'm using the concept of impersonation to implement "File Upload functionality".i.e.
to save the file uploaded to a network share.This n/w share is accessible to an application id only.So i'm impersonating with that user id when uploading a file. I'm importing "advapi32.dll" and using the LOGONUSERA method of that dll to validate the user and get the token for that userid and then impersonate using the Token returned. THis approach is working fine in the development environment but LOGONUSERA always fails in TEST and PRODUCTION environments. It always return "0" which means user id is invalid and the token is zero hence i cannot impersonate. Is it something related to accessing the dll in other environments? Any suggestions to resolve this issue will be a great helpp for us. We are hung with this issue for the past 5 days.
since asp.net contains multiple threads that are executing at the same time.so if 2 threads access an object (simple or complex) that i got from the the asp.net httpcontext Cache.can't this lead to state problems on that object if these 2 theads tried to modify/read it at the same time?so what kind of precautions should i implement?for example i am thinking maybe locking the object while working with it? (wont this cause performance problems?)or maybe when i retrieve some object from the cache i should create a copy from it? or maybe i dont need to worry about this issue at all?
developing an application or simple script in asp.net which basically checks the md5 checksum of a file which will be my web application, and i want it to be compared with the original and be able to alert me of any changes ie defacement.
Question: Anybody has experience with ZedGraph / MS-Chart controls ?
I am thinking about which to use ?
Basically, I have a tendency to ZedGraph, because I need .NET framework 2.0 while MS-Chart is 3.5 (and I don't know how well a 3.5 assembly works on 2.0) and because I could use it privately, too (I use Linux privately).
But I don't know if MS-Charts offers more. Does ZedGraph for example offer reasonable quality 3d piecharts ? And reasonable color design, like gradient colors ? And if it does, is it as simple (or nearly as simple) as MS-Chart controls ? And does ZedGraph offer databinding, e.g. a datatable from a database ?

I hate webform that no matter what action is done with a client side page(such as clicking a dropdownlist to only see the Items), it cause a postback&re-rendering of the whole page and all of the page events is raised( page_init,page_load....complete....).
We know that the server side .cs page shoudnt have to go through all the events and many methods(such as "IsPostback",viewstate), in fact,it just have to do only one thing:get data from DB for the dropdownlist and show it to us, other part of the page just doesnt have to change.
We may achieve this effect using Ajax, but the key is I dont wanna raise too many useless event .
seems MVC can handle such a problem, one action of browser side is replied by exactly one method,and time isnot waste by raise event...
I am looking for an open source CMS for ASP.NET MVC. I have found MvcCms, N2, and AtomicCMS. I'm looking for any advice, anecdotes, resources or articles comparing the different open source projects so I can find the best one for my project. I'd like to find information about the features, extensibility, relative reliability and continued development of the different projects.
I have two data tables, Results1 and Results2. Results1 are used to hold records that matches with the user selection criteria. Results2 holds records that matches with the user selection criteria with one search criteria omitted.
The two tables have identical fields. I need to get all the records that match Field 2, Filed 3 and Field 4 in both of the tables.
Can compare one record at a time with all the ohers but would like to find a more computationally easier method to do this....
What is the preferred way to handle this? Delegates? I have a dropdown box of comparison operators = <, <=, > , >=, == which is used to set up a filter. The filter expression is exactly the same for every case other than the operator. I can do it through a switch, but I am sure there is a one liner that can handle to entire problem. Just not sure what it is?
