View 2 RepliesI'm trying to create a webpage, that on clicking a button on a webform invokes a command line program like
ProcessStartInfo startInfo = new ProcessStartInfo(@"program.exe");
startInfo.Arguments = @"parameters";
Process.Start(startInfo);
morestuff();
The program takes about 3 secs or more to complete it's process running via command prompt. This creates a file that is then read by the next method morestuff(); My problem is that after Process.Start() it moves over to the method morestuff and the file is still not created and throws an error - file does not exist. How do I make sure that the process.start is complete before executing the method morestuff()?
Please share resources to see, how MVC + WCF + EF work together.
View 3 RepliesI'm in the middle-end of written a big website that work a lot with the db.
In every call a page runs 5-12 different queries.What I did was build an execute class that uses MySqlConnector API, which get string that represent the sql and the parameters and then just execute the query and return DataTable. In addition to that I have a class that hold all the function that call the execute class functions. For example in the class I have getAllProducts, getOldestProducts etc... and in each and every one of them theres sql statements.
Recently I watch the LINQ video series(How Do I with LINQ - on this site) and it looked good.As I sees it my way is very good because it just open connection execute the sql get the result and close the connection.The question is what is the best performance wise way to build this site? Is it my way that I use all along? Is it using LINQ? Or working with DataSet/TypedDataSet is the preferred way?
System.NullReferenceException: Object reference not set to an instance of an object

In Windows XP, I used the following command line to tie a particular website to a particular version of .Net Framework:
C:WindowsMicrosoft.NetFrameworkv2.0.50727 aspnet_regiis -s w3svc/1/root/sdcrrlf (sdcrrlf is the website and is written in ASP.NET 2.0; hence uses v2.0.50727; some other of my sites use V1.1.4322)
This command line does not work in Windows 7 with IIS 7.0; error message says path is incorrect.
I've been reading recently about EF4, and how to build an architecture for asp.net web forms application using it.
I explored using POCOs (self tracking entities), with WCF, but found out that my application will be deployed on a single box (i.e. one tier), so I started reading about logical separation of layers, and came up with the following solution:
DAL layer that contains EDMX model and EF APIs, and also generated context object.Entities DLL that holds all generated POCO entities using ADO.NET POCO entity generator. (for persistence ignorance, and decoupling entities from DAL).Business layer that contains a façade for each related group of business functions, the façade will be aware of and using DAL layer. And in each function, it will initiate context and uses different entities to carry out specific job (i.e. function).UI layer that only calls the business layer façade classes. With no awareness of DAL, but it will be aware of entities (i.e. using entities DLL), as the business layer will return results basically as entity collections.
I want to know what you think about this architecture.
I also read about an architecture that uses repository and unit of work patterns, but what I understand that context object is already implementing a UOF pattern, and also object sets are implementing repository pattern (correct me if I'm wrong), so the only advantage of using additional abstraction over them is to make the business layer communicates to my classes, not EF classes, and this is good only if the DAL strategy might change (i.e. by using another tool other than EF, which is not my plan).
Can you give me an scenario example how you have used polymorphism in your project. With new and override keyword.
give me an example from a finance domain/ecommerce domain. I am looking from a UML Model Perspective.
I have a requirement below;Step 1: I must insert and update record with "xx" Running Number into Tables in Database.Step 2: I must send "xx" Running Number from Step 1 go with Web Service and wait the response.Step 3: If Step 2 has a error. I must roll back Step 1 data that I do in Step 1. But If Step 2 is success, everything is Ok.How can I solve this requirement? and How can I write asp.net code?

If I have a variable that contains text information (say taken from a textarea), how can I read the text content held in a string variable line by line?
The text entered in the text area will have (enter key) to separate the line.
I insert a text box, change the parameters to multi line and then pass the string to sql. Users insert comments etc, using line breaks, however because I just pass this as a string the line breaks are not there when they view the text box after input. Example: Here is a well formatted comment. as I typed in the text box today. Inserted in to sql as a string, returns this on select:

i want to create a centralised business or Service authendication architecture in .net. for example, we have a clients like c1, c2, c3, c4, ... etc. everybody logins seperatly as well as grouply. ie, if client "C1" logins [with login authentication] he can access c2 , c3, c4 also without login authendication. So its like a google. if we enters gmail account, we can access orkut, picasa like that.. i need the cetralised architecture.
And, client "c1" seperately asks seperately how will be the authendication architecture.
so give me the single solution for both these two scenarios. how will be the architecture for these two and how is the Data Base (Login) Structure.
recently i've studied on ADO.NET's Entity Model Framework and say 'wow' as ORM is one of the fevourite pattern i practice..but suddenly i've come to an ambiguous situation when i'm going to start. i usually follow the following 3-tier architecture..
1. UI Layer
2. BLL - business logic layer
3. DAL - Data Access Layer
a. DTO / DAO
b. Gateway (contains the sql query/stored procedure and connection with DB)
now when i'm going to use the Entity Model Design,where the DBML/ .edmx File should be placed? Because many a times i'm using the DBML file as DTO because of the mapped objects.. in the same time, sometimes DBML ( .edmx file in .NET 4.0) contains CRUD methods and stored procedured method as well as methods with different selection operations,- which should be in Gateway. so where the .edmx file should be placed !?!! IN DTO namespace !? or in Gateway namespace!
moreover sometimes there is no need for the BLL which breaks the rules of inter-layer-communication (UI > BLL > DAL.Gateway)! what makes me confuse is, what should be the ideal n-tier architecture when i'll use the ADO.NET Entity Model Design Framework
