MVC / Ninject - Single Instance Per Request For Multiple Constructors?
Oct 9, 2010
Im trying to implement an unit of work pattern by passing an unit of work instance into my repositories.
Relevant code from Global.asax.
[code]....
What i want is that a maximum of 1 instance of SqlUnitOfWork is created per request and is passed into my repositories (via their respective constructors).
Is the InRequestScope() method on the IUnitOfWork binding enough? If not how can i achieve this?
1.) What is the name of the OS process in which App Domain resides.
2.)if suppose There are Three Windows application hosted on a same envoirment and two instance is working for each application at a Time, means now total instance are six .what will happen among the below written cases :
a.) There will be six different app domain in a single OS process
b.) There will three app domain(one for each application) in a single OS process and some Parallel thread will be executed in each app domain for another instance.
c.) There will be Three OS process corresponding to each application.
3.) If eveything will remain same except there are three web application in place of windows in point 2, will there be any change in functioning.
I'm trying to learn the ropes of ASP.NET MVC and so far so good. One thing which I haven't seen addressed yet is the 'right' or most elegant way to pass multiple data models to a view. To help put the question in context, take this example: Say I was making a blog. When I log in I want the home screen to display a list of all new unapproved comments, as well as a list of recently registered users, and a list of the most recently submitted blog posts.
Most discussions I've seen suggest strongly-typing the view page so it can be called with something like "return View(RecentComments)" and iterate through the comments in the view, or to cast the data model like "var NewUsers = (MembershipUserCollection) ViewData.Model". What I'm ideally after is the 'right', or at least a 'right-enough', way of passing multiple models while still maintaining appropriate logic separation.
I have a stored procedure that returns 3 tables within the single recordset it returns. If I set a SqlDataSource to get data from this procedure, it works, but it only returns the first table. I want to have a GridView display the data from the 2nd or 3rd table using a SqlDataSource, but I can't figure out how to specify a particular table.
While there are some posts discussing this out there, I can't get a definitive answer about whether or not this is even possible (?). In a worst-case scenario, I can create another SP that only returns the 3rd table - but that creates a little maintenance headache that I would prefer to avoid.
I have a question in gridview, I want to combine my two or more records into a single cell with two rowsfor Example i have a ID, Name, Year Start, and Year End for Column name in database and i want call it into my gridview that the Year Start and Year End will combine to Year like:
I am developing the web site, It consists of device name list and related Build Button. When one click the Build button the one process will run in server. When more than ten user click the Build button more processes will create at that server will hang. How can send all request from client to single process in server.
I have an ASP.NET HttpModule that is distributed as a DLL. I badly need a plugin architecture so I can isolate some heavyweight, rarely used features into external .dlls, and speed up/slim up the core functionality.I've experimented with (1) reflection and (2) static constructors.It seems GoDaddy and a few other web hosts prohibit use of Reflection, making #1 useless..NET 4.0 now calls static constructors lazily, eliminating #2.
How can I have a generic plugin registration system that doesn't require C# or VB code to register the plugins? Even a web.config plugin registration list would be fine, but I don't know how to do that without using reflection.
Update: I need this to work in .NET 2.0 as well as higher versions
i have a page in my webapp, in which a pdf is created. When the page is loaded, parameters are read from the querystring and the process of building the pdf starts. This contains two xslt transformations and one antennahouse-fo-formatter call. The result of the first xslttransformation is written into an memorystream, which is the source for the second transformation. The result from the second transformation is the source for the pdf-generation. Our live-system is an loadbalanced-system containing two servers. The page works for a while, but at once the page fails on one server with the following exception:
I am trying to create a simple page with a drop down list which has 3 items. Choosing any of those 3 items calls for a specific constructor in the script. Using VB 2008
public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e) { if (DropDownList1.Text == "Coupe") { //Response.Write("You chose the Coupe"); string Engine; string Transmission; string Wheels; string Safety_Features; string Key_Systems; string Interior; string Mileage; Altima A1 = new Altima(Engine, Transmission, Wheels, Safety_Features, Key_Systems, Interior, Mileage); Response.Write(A1.displayAuto()); } if (DropDownList1.Text == "Hybrid") { Response.Write("You chose the Hybrid"); } if (DropDownList1.Text == "Sedan") { Response.Write("You chose the Sedan"); } } public class Altima { //private member variables private string Engine; private string Transmission; private string Wheels; private string Key_System; private string Safety_Features; private string Interior; private string Mileage; //public accessor methods public void displayAuto() { System.Console.WriteLine(Engine, Transmission, Wheels, Safety_Features,Key_System, Interior, Mileage); } //constructors public Altima(string Engine, string Transmission, string Wheels, string Safety_Features, string Key_System, string Interior, string Mileage) { this.Engine = Engine; this.Transmission = Transmission; this.Wheels = Wheels; this.Key_System = Key_System; this.Safety_Features = Safety_Features; this.Interior = Interior; this.Mileage = Mileage; string Engine = ("2.5-litre DOHC engine with 175 HP and 180 lb-ft of torque or 3.5-litre DOHC engine with 270 HP and 258 lb-ft of torque"); string Transmission = ("-speed manual transmission or available Xtronic CVT® with manual mode"); string Wheels = ("17 inch 5-spoke aluminum-alloy wheels (2.5 S) or 18 inch 5-split spoke aluminum-alloy wheels (3.5 SR)"); string Safety_Features = ("Six standard air bags as part of Nissan Advanced Airbag System (AABS)"); string Key_System = ("Nissan Intelligent Key® with Push Button Ignition"); string Interior = ("Leather"); string Mileage = ("Up to 5.6 L/100 km on city with eCVT"); }//coupe -------> First constructor public Altima(string Engine, string Transmission, string Safety_Features, string Mileage) { this.Engine = Engine; this.Transmission = Transmission; this.Safety_Features = Safety_Features; this.Mileage = Mileage; string Engine = ("2.5-litre DOHC engine with 175 HP and 180 lb-ft of torque or 3.5-litre DOHC engine with 270 HP and 258 lb-ft of torque"); string Transmission = ("-speed manual transmission or available Xtronic CVT® with manual mode"); string Safety_Features = ("Six standard air bags as part of Nissan Advanced Airbag System (AABS)"); string Mileage = ("Up to 5.6 L/100 km on city with eCVT"); }//sedan -----------> Second Constructor public Altima(string Engine, string Transmission, string Mileage) { this.Engine = Engine; this.Transmission = Transmission; this.Mileage = Mileage; string Engine = ("2.5-litre DOHC engine with 175 HP and 180 lb-ft of torque or 3.5-litre DOHC engine with 270 HP and 258 lb-ft of torque"); string Transmission = ("-speed manual transmission or available Xtronic CVT® with manual mode"); string Mileage = ("Up to 5.6 L/100 km on city with eCVT"); }//hybrid -----------> Third constructor } }
how do I ouput the values from the constructors when I choose the specific list box item?
my solution in VS 2008, consisting of a dozen projects, does not compile because it gives me errors on constructors of a couple of classes, telling me that lacks the constructor that takes one parameter, which lacks the parameterless constructor, and so on.Actually I have all the correct constructors, and other times I compile without problems.I'm not understand why I have these random problems, that it is practically impossible to replicate.
"With ASP.NET I've found that request are processed sequentially, one at a time, at least on a server with one CPU. If one request blocks for some reason, maybe on a long database query, then all users must wait until it completes, for their request to process."
Is this true? Do multi-core processors effect this? Also if you do ahve more than one CPU will it stop processing sequentially automatically or is the default always sequentially?
I have a webservice, it has few webmethods. when i create a client proxy and invoke the methods to check its response, i am getting this error. Can someone tell me what things can i check to know the cause of this? The error is not saying much hence blocked on this.
I have 3 Databases that I am pulling data from for my web site. 2 of the databases are in the same SQL instance, however the 3rd one is in a different SQL instance. Both of the SQL instances are installed on the same server, one of them is a Named instance and the other is installed under the default instance. So my connection strings look something like this:
I'm in the process of moving this application from the Development Server to the Production Server when I noticed this issue. Previously the ABC and BCD connectionStrings where pointing to a different server and instance. So my question is how do I get this wo work with the server names being the same but the instances being different?
I am using forms authentication in asp.net application. This is working fine in internet explorer. Opening application in firefox is also fine but when i login in second instance of firefox, application in first instance logs out. Following is my code for creating ticket and cookie.
FormsAuthenticationTicket objTicket = new FormsAuthenticationTicket(1, sUserName, DateTime.Now, DateTime.Now.AddMinutes(60), false, "");
i have to use two different Ajaxfileupload controls in a page .But when i upload file through second control the second event doesnot get fired(UploadComplete) everytime first event is fired.
Ive searched everywhere, i can't seem to find a way to implement ninject in my project. Ive heard of deriving MvcApplication to the NinjectHttpApplication. But NinjectHttpApplication isnt found even if i add the lib to the reference. I can't find Ninject.Web.Mvc. Does anyone have a guide somewhere in order to make this work, all i want to do is be able to bind my interface from my domain to existing implementation.
I have a web application using window authentication. There are a search page and a edit page in the application. In search page, user can enter some search criterias in the textboxes and the search result will be displayed in the gridview by clicking the "Search" button. User can select any row from the gridview and it will take him to the edit page. In the edit page, there is a "Back" button to take the user back to the search page. I use session variables to remember what the search criterias the user entered in the textboxes and what page number the user was in the gridview. So when the user goes back to the search page, the textboxes are pre-populated with the search criterias and the gridview is displayed in the correct page number.
The problem is: If user1 opened one browser window and did a search using search criterias1, then user1 opened a 2nd browser window and did a search using search criterias2. When the user1 went back to the search page from the edit page using the first browser window, all the textboxes and page numbers are from the 2nd browser window, instead of the 1st one. Can anyone explain this problem to me and how to prevent it? It will be helpful too if you can give me some links about the similar problem. I am thinking if the same user logged on two different machines and did the search on each machine, what is the result?
