No mapping exists from object type System.Web.UI.WebControls.Label to a known managed provider nativ

  
 I'm making the leap to move from vb.net to C#, and I'm getting this crazy error when I try to execute one sp, set a value, and then execute another sp based on the value.   Any suggestions??? proc_GetSectionDetails is my first stored procedure.  From that, I get a value for SectionID, and then use it for the second sp called  proc_GetSectionDetails protected void getSectionContent() { SqlConnection conn = default(SqlConnection); SqlCommand comm = default(SqlCommand); SqlDataReader reader = default(SqlDataReader); string connectionString = ConfigurationManager.ConnectionStrings["123"].ConnectionString; conn = new SqlConnection(connectionString); comm = new SqlCommand(); comm.Connection = conn; comm.CommandType = System.Data.CommandType.StoredProcedure; comm.CommandText = "proc_GetSectionDetails"; comm.Parameters.AddWithValue("SubSectionID", Request.QueryString["SubSectionID"]); conn.Open(); reader = comm.ExecuteReader(); if (reader.Read()) { lblName.Text = Convert.ToString(reader["SubSectionName"]); lblDesc.Text = Convert.ToString(reader["SubSectionDescription"]); Label SubSectionParentID = new Label();

chart object in toolbox vs 2010

  

Hi,

I am trying to use the chart object provided in vs 2010. 

Specifically, I am trying to use the chart object to create a web part.

I noticed that the chart object did not appear in the toolbox when I opened it. I found a link that suggested I run an install program to add the chart object in. I now have the chart object appearing in the toolbox, but when I attempt to drag it onto the form I keep getting messages about "Error Creating Control" - Object reference not set to an instance of an object.

Where should I go from here? Is the chart a bit unstable? Do I need to reinstall from elsewhere?

 

Thanks.

 


No mapping exists from object type System.Xml.Linq.XDocument to a known managed provider native type

  

Hello,

I am using XML in getting client data in 3-tier architecture, using XDocument in passing XML among layers.

But when I use it in inserting this XML in XDocument, it throws the following error:

No mapping exists from object type System.Xml.Linq.XDocument to a known managed provider native type. 

I am using the following code, it throws the exception at the bold line:

 public void DALInsertXML(XDocument x)
        {
            SqlConnection connection = new SqlConnection(connection1);
            connection.Open();
            _command = ne

Thinking about new C# method prototypes: object as dictionary

  
I recently had to write a small Flickr API. I know many .Net API for Flickr already exist but I needed one for a Silverlight application. Whatever, it's only about building some querystrings so I did it by myself. It's been an opportunity to think again about a classical question: how to pass parameters to a method ?

Imagine you have a generic method to call some Flickr functions.

C# Object Oriented Programming

  
So far in C# Essentials we have looked at the basics of programming in C# such as variable types and flow control. Although it would be possible to write a functional program using these techniques, there is much more to becoming a proficient C# programmer. C# is, above all, an object oriented programming language and as such any C# programmer will be expected to create object-oriented applications using this language.

Object Oriented Programming

  
Four core concept of OOP Object Oriented Programming. 1.Inheritance, 2.Polymorphism, 3.Abstraction and 4.Encapsulation

Object-Oriented Programming Concepts

  
This is the first in a series of articles describing the use of object-oriented programming techniques as implemented by the C# programming language. This series follows the C# Fundamentals tutorial that beginners are advised to read first.

Overview of SharePoint Object Model

  
SharePoint offers a set of structured server-side objects those are widely used to program SharePoint Applications. These objects are hierarchically arranged and you can drill down through the object hierarchy to obtain the object that contains the components of SharePoint Application you need to use in your code.

What is the difference between "dynamic" and "object" keywords?

  
Let's take a quick look at the object keyword first. I'm not going to talk a lot about it because it's been around since C# 1.0. This keyword is nothing more than a shortcut for System.Object, which is the root type in the C# class hierarchy. (However, as Eric Lippert pointed out in his blog post, not everything in C# derives from object.) This is a powerful mechanism, since you can assign almost any value to instances of this type.

How to bind GridView and DropDownList controls using DataTable object

  
In .net framework 2.0, you can load a DataTable in memory by consuming a data source using a DataReader. In this version you will find the flexibility in accessing the DataReader means write access code once and use again and again using DataReader. To see the functionality of DataTable consider an example that is created using VS2005.

Jscript error: Object does not support property or method

  

 Hi, i have little knowledge on javascript but i need to use this code get from somewhere for a jquery to work.

I face this "Jscript runtime error: Object does not support property or method" whenever im trying to run this page.

In my experience, im get this error msg 9 out of 10 times i use javascript in my system.

Im using Microsoft Visual web developer 2008, i wonder if this is related to my problem, i not sure there is anything i need to add as reference or update anything.

But anyway, in short, i just couldn't use javascript code when using this development tool because of this sort of error.

Anyway, it happen that last time i tried use the same type of jquery code in another project and it seems to work well without an error.

But now when im try to use it again in this recent project i created, it come out with this error and i have no idea how to solve it even look through google and this forum.

It doesn't really seems like its the code problem itself although im not sure, because any javascript code just couldn't work.

So below is my code that i need to use.

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" ></script>
<script type="text/javascript" src=&quo

Pass ASP.NET membership identity object across domain?

  

I am trying to figure a way to SSO with ASP.NET membership and role model.

I can implement custom membership provider which consume web services hosting on a server.

With encryption of data. No problem.

But my question is, If I sign on a website with my provider, got my identity object on that application,

could I pass it to another website on another domain which use the same provider and by doing so, do not need to login again?


If this is possible, I am going to implement this solution. Please tell me what's your take on this.
