1) I want to know what is the recommended way to create & return a DTO for an object which has 10 attributes and I only want to return 2 with my DTO object.
2) Should DTO's have their own namespace ? If yes, how do we organize them ? Each DTO inside a single class file or all DTO's inside a single class ?
I have a Google spreadsheet that I am reading data from and I want to load the data into a list object so I can use but I am having some issues.
Google Spreadsheet
-Worksheet name: Charts
-Tab: Color_Summarized
-Column 1: ColorSummary
-Column 2: ChildID
-Column 3: ParentID
sample rows:
Aqua|29|28
Blue|49|23
Yellow|55|28
My results are
Yellow Color_Summarized FH 55 28
How do I need to set it up so it keeps all the data loaded instead of just the last instance? Is there a better way then putting in class?
My code:
Code:
Imports Microsoft.VisualBasic
Imports System.Data
Imports System.Collections.Generic
Imports Google.GData.Spreadsheets

I need to add some attributes [URL] to the tag in an ASP.NET Page object. Note: I cannot do this in a declarative manner and have to use the server side object model to do it.
To add some additional information:
I need to do this within the ASP.NET Page rendering life cycle.
I need to add the attribute to the root element in the page.
I am using C# & mvc and have an aspx view page where I am trying to use inline code to set the style of a div elemnet:
<div id=MyDiv>
<%= MyDiv.Attributes.Add("class", "MyClassStyle") %>
</div>
But when I type the inline code in I get the error
"Cannot implicitly convert type 'void' to 'object'".
Whereas some of the Attrbute methods work fine like
<%= MyDiv.Attributes.Count %>
What is the void it is refering to, is it possible to set the styles like this inline,
Is it possible to add attributes in a linq query along with the other object data?

I am accessing this xml file by using LINQ to XML in asp.net by using C#. I am able to access all the attributes of an XML node by explicitly specifying the name of the attribute. I want to write query on this xml file which reads all the attribute values of the xml node (In our example the node is SERVER) dynamically means I want to write the query which can read the read the value of the attribute Name & ID from first node, only name from second row, Name, ID & Parent from the third row , Name & ID from the fourth row, Name, Parent & Value from the fifth row & only Name from the sixth row without modifying the existing code every time. Once I add one of the attribute ( for example if I add the attribute ID in the sixth row ) in the above xml file then I dont need to modify my LINQ to XML query. My query should dynamically fetch the total number of attributes & display their values. Is their any way to do this ?
I think the title pretty much says what I'm trying to do. I'm trying to make several applications with C#, ASP.NET, and active directory. Right now, I'm trying to create a report for my manager that shows all the active directory attributes of the current user. Could someone show me the code for this. I would want to add a new row into a datagridview for each attribute.

What's this ? How to instantiate object of my classes ?
View 4 RepliesI'm a little green when it comes to streaming and serialization...but what i wanna do is make the Upload method on the server return a serializable object to the client (it is void right now). I have a public class ServiceResult that i decorate with [Serializable], and a public class FileTransferService that implements IFileTransferService
[ServiceContract()]
public interface IFileTransferService
{
[OperationContract(IsOneWay = false)]
string Upload(FileTransferRequest request);
}
The implementation does its thing, and then at the end i create and serialize the object and try to return the string
return ServiceResultSerializer.SerializeAnObject(result);
On the client side i call this service using this class
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0")]
[System.ServiceModel.ServiceContractAttribute(ConfigurationName = "IFileTransferService")]
public interface IFileTransferService
{
// CODEGEN: Generating message contract since the wrapper name (FileTransferRequest) of message FileTransferRequest does not match the default value (Upload)
[System.ServiceModel.OperationContractAttribute(IsOneWay = false, Action = "http://tempuri.org/IFileTransferService/Upload")]
string Upload(FileTransferRequest request);
}
I'm basically taking this project found on this blog: [URL] And trying to make it return a value that the client caller can use I get an error right now that says: The operation 'Upload' could not be loaded because it has a parameter or return type of type System.ServiceModel.Channels.Message or a type that has MessageContractAttribute and other parameters of different types. When using System.ServiceModel.Channels.Message or types with MessageContractAttribute, the method must not use any other types of parameters. Which i have no idea what it means :P I think cuz im trying to change the Service paramaters.
I have the following ActionResult() method:
[Code]....
The method is called once the <form> is submitted. If the validation is good, it moves on to create a new user Once the new user is created, I want to redirect the user to a "ThankYou" page passing along the newly created user (object). The TempData["User"] trick seems to work like a charm! Then inside my ThankYou ActionResult() I do the following:
[Code]....
The problem I have is once the user has been redirected to the "ThankYou" page. If he decides to refresh (F5) his browser, the value in the TempData is lost.
What are my possibilities to overcome this issue?
Instead of passing an entire object to my "ThankYou" page, I initially thought of passing the ID of the newly created user and re-query my database to get the object.
The only problem is that the ID will be seen in the QueryString allowing the user to simply change the ID value and try to find other users...
Is my only other alternative to simply place the user object inside a Session? Is that my only other option?
Is there any way to return object from Session when Select is called on ObjectDataSource? Specifically, I have Products object and saved in Session. Now on another page I have ObjectDataSource which will call same bussiness object method to get Products object. Here I want to hook up any event like Selecting and I would like to return Products object from Session to Select method of ObjectDataSource.

View 1 Repliesmy controller, I'm generically deserializing Xml. The object being deserialized to could end up being any number of different types. This, of course, won't be known at compile time. I've created a number of partial views, each of which are strongly typed to a different object that is a possible outcome of the Xml deserializaton.My problem is that I'm struggling with a good way to return the right view. I could always switch on some property in the object, or use a Key/ViewName Dictionary mapping to get the right view name, but I was hoping for something a little more generic than that.Does anyone know of a way that I could implicitly say, "return the view that is typed off of the object I have."?

I have a products table whereby I want to return a single row via a product id and use it as a data object.
I have used a .xsd dataset and a product class where I return a dataset and add the values into the product object that I created but I don't like having to write code like
"Product[0].ProductDescription" to get the product description. Is there a way of returning is straight as an object rather than a dataset?
How would I go about checking a page for form objects and returning all of the object ID's? I don't even know how to return page source.
View 10 RepliesIf I'm returning an object, then it's pretty straight-forward. However, if I'm just trying to return whether or not the method was successful or not, what's the best option? Sure ... bool seems obvious - but what if you need to debug or get some additional details out of the method than just "yes/no"? Well that's where a string becomes more obvious, right? You can leave it empty to say that the method was successful or chock it full of details in the case of an error. But this can make it less intuitive to others who may have to run your functions and it also jumbles up everything you wanted to pass back into one large string.
