What is C Sharp Using statement

The Using statement in C# allows you to define the scope of an object lifetime, when the end of the using satament is reached  the object Dispose() will be called immediatly.

using (SqlConnection conn = new SqlConnection(connString))
{
     SqlCommand cmd = conn.CreateCommand();
     cmd.CommandText = "SELECT * FROM Customers";
     conn.Open();
     using (SqlDataReader dr = cmd.ExecuteReader()) {
          while (dr.Read())
          // Do Something...
     }
}

This is extremly useful when we need to release a resourece intensive object, like database connection object or a transaction scope

Sharepoint 2010 Connectable webparts

 This post describes how to create connectable webparts in Sharepoint 2010

A webpart that provides a string and another webpart that consumes and displays the value of the string.
These are the tasks to be followed :

1. Creating an interface to define the string that is being provided.
2. Creating a webpart from Visual Studio Webpart item template
3. Creating a provider webpart that defines a string
4. Creating a consumer webpart that uses and displays a string
5. Creating a webpart page and connecting the provider and consumer webpart.


A)  Creating an empty sharepoint project :

1. Start Visual Studio 2010 in administrator mode.
2. On the File menu, point to New, and then click Project. If Visual Studio is set to use Visual Basic development settings, on the File menu, click New Project.
3. In the New Project dialog box, expand the SharePoint node under the language that you want to use, and then select the 2010 node.
4. In the Templates pane, select Empty SharePoint Project.
5. For the name of the project, type ConnectableWebParts, and then click OK.
6. In the What local site do you want to use for debugging? drop-down list, select the local site that you want to use for debugging.
7. Select Deploy as a farm solution, and then click Finish

 B) Creating an Interface : (what is an Interface?)

   

          public interface ITextBoxString

          {

             string TextBoxString { get; set;}

          }  

C) Creating a Provider Webpart

1. In Solution Explorer, click the ConnectableWebParts project.
2. On the Project menu, click Add New Item.
3. In the Installed Templates pane, expand the SharePoint node, and then click 2010.
4. Click Web Part, type StringProvider for the name of the Web Part, and then click Add.
5. In the StringProvider.cs or StringProvider.vb code file, add the following code to indicate that the StringProvider class implements the ITextBoxString interface.

  public class StringProvider :Webpart, ITextBoxString
  
   6. Add the following code to create a text box, string and a button
 
     private TextBox myTextBox;
     private String _textBoxString = String.Empty;
     private Button myButton;

   7.  Implement the get and set method of the ItextBoxstring interface by adding the following code:
  

 
  [Personalizable()]
public string TextBoxString
{ get
    {
        return _textBoxString;
    }
    set
    {
        _textBoxString = value;
    }
}

                                               (what is personlisation)

  8. CreateChildControls(): instantiates controls and adds new control to the webpart
   
protected override void CreateChildControls()
{
    Controls.Clear();
    myTextBox = new TextBox();
    Controls.Add(myTextBox);

    myButton = new Button();
    myButton.Text = "Change Text";
    Controls.Add(myButton);
    myButton.Click += new EventHandler(myButton_Click);
}

9. Code to handel Click event

protected override void CreateChildControls()
{
    Controls.Clear();
    myTextBox = new TextBox();
    Controls.Add(myTextBox);

    myButton = new Button();
    myButton.Text = "Change Text";
    Controls.Add(myButton);
    myButton.Click += new EventHandler(myButton_Click);
}
10. Create a method to return tothe ITextBoxString object to share to other webpart.  Apply the ConnectionProviderAttribute attribute to identify the callback method that acts as the provider in a Web Parts connection.


[ConnectionProvider("Provider for String From TextBox", "TextBoxStringProvider")]
public ITextBoxString TextBoxStringProvider()
{
    return this;
}


D) Creating a Consumer Webpart

1. In Solution Explorer, click the ConnectableWebParts project.
2. On the Project menu, click Add New Item.
3. In the Installed Templates pane, expand the SharePoint node, and then click 2010.
4. Click Web Part, type StringConsumer for the name of the interface, and then click Add.
5. In the StringConsumer.cs or StringConsumer.vb code file, add the following code to create objects for an ITextBoxString provider and a text box.

private ITextBoxString _myProvider;
private Label myLabel;

protected override void OnPreRender(EventArgs e)
{
    EnsureChildControls();
    if (_myProvider != null)
    {
        myLabel.Text = _myProvider.TextBoxString;
    }
}

protected override void CreateChildControls()
{
    Controls.Clear();
    myLabel = new Label();
    myLabel.Text = "Default text";
    Controls.Add(myLabel);
}

 [ConnectionConsumer("String Consumer", "StringConsumer")]
public void TextBoxStringConsumer(ITextBoxString Provider)
{
    _myProvider = Provider;
} 

E) Connecting the Provider and Consumer Webpart

1. In Solution Explorer, click the ConnectableWebParts project.
2. On the Project menu, click Add New Item.
3. In the Installed Templates pane, click Code.
4. Click Interface.
5. Type ITextBoxString for the name of the interface, and then click Add.
6. In the ITextBoxString.cs or ITextBoxString.vb code file, mark or verify that the ITextBoxString class is public

How to force uninstall a program you cannot uninstall

1. Click Start and choose Run in the menu (If you're using Windows Vista then press Win+R on your keyboard).
2. Type regedit and hit Enter.
3. On the left side is the registry settings tree, use it to go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
4. Inside that key you'll find a lot of keys that belong to different programs. Some are named after the program's name, others as a mix of numbers and letters that makes no sense. Look through each of them until you find one that has the key DisplayName (on the right) with your program's name in it.
5. Notice the key UninstallString - this key points to the uninstall program, and the log file usually resides in the same folder as that program.
6. If you delete the key in which you've found the DisplayName key with the value equal to your program's name, then your program won't appear on the Add/Remove programs list

What is CAML

Collaborative Application Markuup Languae is the XML-based language that is used to build and customize web sites based on Sharepoint team Services

CAML can be used to do the following:
 Provide schema definition to the web site provisioning system about how the site looks and acts
 Define views and forms for data and page rendering or execution.
Pulling a value from a particular form

Why do we use CAML:
CAML allows you the ultimate flexibility and extensibility with your Web sites based on SharePoint Team Services from Microsoft. If you want to make a universal change to all the sites that you are creating within your company — for instance, you want to change the logo to match your own company logo, or you want to add an Employee ID field to your document libraries — you must use CAML to do it

Location of CAML:  ( read more )

CAML Query tool :
Collaborative Application Markup Language (CAML) is an XML-based language that developers can use to create custom views and query SharePoint lists. Because it can be difficult to write anything other than basic queries, many tools have been developed to simplify this task. Several of these tools allow developers to write CAML queries within a designer. This is similar to the way developers write SQL queries for many commonly used databases.
