Reserve Methods For The Data Mapper?
Feb 10, 2010
I have a situation where I have two assemblies - one called "business objects" and another called "data mapper". This is to allow me to swap out the data mapper if necessary with no change to business logic.
When loading objects from the database, there are certain methods and properties within these objects that it's convenint to allow the data mapper to access directly so as to simplify the process of construction. However, I'd like to make sure that these methods are only available to the data mapper - because otherwise you can guarantee that some developer will go and use them, short circuiting the business logic.
Even if I prefaced the method names with eg DatamapperOnly, I'd bet that someone would be stupid enough to use them "because we needed to get the application out in a hurry".
Can anyone think of any way to prevent this? For example, is it possible to create a custom <datamapperonly> attribute to be applied to methods which would cause the application to warn the developer at compile time unless the calling program implemented an interface called IDataMapper?

We are developing SOA based application using .NET 3.5 and WCF & WPF.
One common issue we are facing is mapping between WCF enum and WPF enums. We had to do mapping between WCF enums to WPF enums. Following is sample code
Switch(WCFServiceObject.Status)
{
Case WCFServiceStatus.Married[code]....
You can see that we have to do mapping WPF and WCF enums. Is there any easiest way to achieve this mapping without writing tedious switch statements? One way of doing this is using Dictionary, but apart from this, is there any good way? We have lots of enums for which have to do mappings.

I have an extension method as follows:
public static class PageExtensions
{
public static int GetUserId(this Page targetPage)
{
var user = Membership.GetUser(targetPage.User.Identity.Name);
return (int)user.ProviderUserKey;
}
}
Now in a page I need to use this method in a static WebMethod, so I have added another 'extension method' to PageExtensions:
public static int GetUserId()
{
return (int)Membership.GetUser(HttpContext.Current.User.Identity.Name).ProviderUserKey;
}
and I call it as follows in my WebMethod: PageExtensions.GetUserId()

I am beginner in web applications development. I started one little project and host it on source forge "https://homoco.svn.sourceforge.net/svnroot/homoco". And I started implementing authentication in this application to learn how it works. From my experience people never use out of the box things so I want to implement this stuff alone (like in real world projects). So some questions:
1) Is there any reason to use membership out of the box? To use database table schema, stored procedures etc. that tool generate for developer. I think that this lower control over code and I decided to implement it my self. I don't know if I am right.
2) Is my approach in this demo project good or bad (if someone have time I like to do just a little code review)? I created database based on business rules. Not using database schema that membership provider require. Extend "MembershipProvider" class to satisfy my needs. Implement queries to database myself.
3) Now, this question is a little wired but I have to ask it. If we make custom Membership Provider and do sql queries alone, implement all MembershipProvider class methods ourselves, and in application use Membership.blabla() why is this approach different from not extending MembershipProvider class and putting all this methods in some unique class and call its methods then? I hope that someone understand what I ask here.
I am sorry for three questions, but I really trying to find the best way to implement this feature in my demo project like it is a real world application.

1)usign execute scalar i will get 1st col and 1st row value.
2)using dataset i will get whole table.. if my stored proc has 2 queries then i will get 2 tables within same dataset.. i can reference therese using ds.tables(0).rows(value).
3)suppose i use a datareader then i will get multiple-rows. i want to know how to get these each separate rows coloumn values into variables. below is the reader aspx.vb
reader = cmd.ExecuteReader();
while (reader.Read()) {
4)what is it mean by data reader is forward only method of getting data.
5)why do we do readeritem.tostring()
6) can you tell me the basic how is this reader,ds,scalar works.i mean i know to use but donot know basics esspecially the dataadpapter.why do we fill it when using dataset.

I am making updatable pages for my website. I am new to asp.net so I want to find the best method to pull one record from the database. The record will consist of page name and page text. I have test information set up in the database which works of an ID and have constructed a database connection. But I want to use a database control which willl have minimum overhead for pulling out just one record. I won't require any features such as editing or pagination. I was thiking of using the data repeater.

I'm getting ready to start a C# web application project and just wanted some opinions regarding pulling data from a database. As far as I can tell, I can either use C# code to access the database from the code behind (i.e. LINQ) of my web app or I can call a stored procedure that will collect all the data and then read it with a few lines of code in my code behind. I'm curious to know which of these two approaches, or any other approach, would be the most efficient, elegant, future proof and easiest to test.

My requirement is to show a page with multiple filters to apply to grid data.
Suppose we are talking about Orders and an order has the following attributes
public class Order {
public int OrderID
public DateTime OrderDate
public DateTime ShipmentDate
public int OrderTotal
public int OrderStatus
}
Inside the jqgrid object I am showing all the attributes except the OrderStatus
The requirement is to create a view that has the jqGrid on the left part a panel on the right
Inside the right panel the user will see a list of checkboxes that represents every possible OrderStatus value and he want to search using both methods (for example selecting the checkbox "Shipped Orders" and then filtering the grid with Amount greater than a value)
I have already configured the advanced filtering (multiplesearch:true) inside the jqGrid object and I am able to create complex filters combining fields and logical operators.
how I can submit even the data from the right panel when the user press the search button?
Update 1:
Preamble: Oleg sample is fantastic but unfortunately does not fits requirements of my customer :(
@Oleg: I do not understand why you think that:
If the data are outside of the grid you will be show the order details on the right pane only for selected row. So the user will have not so good overview of the data.
maybe my description was not so clear but I am not going to show any order detail. To better clarify my requirement I have modified your sample to show you the desired final UI which is as in the following image:
The customer want to filter the data in the grid using two methods or both together:
Using the multiplesearch facilities provided by the grid itself (thanks for the workaround mention) Using the custom Search Panel (the one with the checkboxes on the right) provided
From a functional point of view the requirement is very easy to express: When the user click on a checkbox or make a search using the native multiplesearch I should post values to the server including also the checkboxes state.
To summarize I should:
Add the checkboxes state when a post is made through the native multiplesearch
Add the current multiplesearch state (if any) when the user click on a checkbox

I am developing a web application, which has Data Access Layer and this layer has only one class, in which all methods are static methods like static Insert, static Update, static Search. It has no properties. I am using these methods in my Bussiness Logic class for my users who are visiting my website.Now my question is : 1. Is it right to use static methods in this scenario ?2. What will happen if 10 users call Insert method at the same time ?

I have created a table adapter in DAL. I have created a gridview in the page and want to fill the gridview with a table data by calling a method. My table has 11 columns but i want to display only 2 columns of the table. My getSong() method has a query as Select title, category from Muisc. But it diaplyas all columns with no data except title and category and the autoincrement primary key column with negative values. The pic is given below. How can i solve it?

I am seriously at a loss here. The three things that will not change in this project are the fact that we are using the Entity Framework to do our data access, the fact that we want thorough unit testing and that our UI is asp.net. My question is how the hell do you make this work in Asp.net? E.g. You can use an ObjectDataSource to connect a method to a control, but if this control is a FormView you have all these problems [URL] to deal with and it simply doesn't work.
Furthermore, with grids, you don't get paging or sorting out of the box unless you use an EntityDataSource which basically circumvents your entire application. I can't be the only person who cries at this. What do you do?

Presently we have converted a project from vs 2005 to vs 2010,
we have using typed dataset as our business object in separate project
after converting that dataset to vs 2010 dataset, datatable is been changed to System.Data.TypedTableBase<dataRow>,
because of that all project getting error saying method/properties not found default method/properties provided by datatable like select,rows, columns.. etc. are not able to access outside that project, but can be accessed with in that project.

which is better approach from performance point of view, is it better to use one web-service method to load data by passing Database Table name and keys or is it better to use separate method for each database table! knowing that i'm using .net asmx through ajax requests.it's obvious that one method is better from OO perspective since it have one function type 'data loading' but what about performance? does IIS affected by that or not? also is it better to make multi web-services 'asmx files' or just one!

I developed a DLL in C# When I am trying to call it I get: System.EntryPointNotFoundException: Unable to find an entry point named: It means that DLL doens't export any methods visible from DLL. Dumpbin doesn't show any methods either:
dumpbin.exe -exports ActiveXTest.dll
Dump of file ActiveXTest.dll

What's wrong? The DLL looks ok.. according to documentation:
Csharp Code:

Here is how I call it:
Csharp Code:
