OData provides patterns for HTTP, JSON, data access

Is OData ready for prime time? Open Data Protocol, OData, is rapidly evolving. This Web protocol used for querying and updating data gives users a way to unlock data, freeing it from silos in today's applications. It defines a set of patterns for working with data based on HTTP, AtomPub, and JSON. OData originated at Microsoft, but more companies are jumping on the bandwagon. IBM, eBay, Facebook and Netflix are all OData enthusiasts, using this protocol to better serve their users.

Using SqlMethods.Like method

The System.Data.Linq.SqlClient namespace includes a helper class called SqlMethods, which can includes a method called Like, that can be used in a Linq to SQL query:

var query = from c in ctx.Customers

            where SqlMethods.Like(c.City, "L_n%")

            select c;

This method gets the string expression to check (the customer's city in this example) and the patterns to test against which is provided in the same way you'd write a LIKE clause in SQL.

Using the above query generated the required SQL statement:

SELECT CustomerID, CompanyName, ...
FROM    dbo.Customers
WHERE  City LIKE [L_n%]

Binding Data to Silverlight 4.0 Controls Using ASP.NET MVC 2.0

Silverlight is a browser plugin that promotes a collaborative development environment of rich online media content that enables developers and designers alike to integrate multimedia and graphics into web pages within the context of the managed environment of Microsoft .NET framework. Over the past few years, Silverlight, formerly known as Windows Presentation Foundation (WPF), has quickly become the technology of choice for developing the next generation of cross-browser, cross-platform Rich Internet Applications (RIAs). ASP.NET MVC Framework is a platform that enables you to design and implement applications that are based on the MVC design pattern. This article takes a look at how ASP.NET MVC Framework 2.0 applications can be used to bind data to Silverlight 4.0 data controls.

ASP.NET caching with Web services

In ASP.NET 2.0, the HTTP method of the test page has changed from GET to POST. However, POSTs are not ordinarily cached. Implementing proper caching in your web services can increase scalability and performance. One of the easiest ways to implement caching systems is with the CacheDuration property of the WebMethod attribute.

Eg.
[WebMethod(CacheDuration=100)]


public string GetCacheEntryTime(string Name)

{

StringBuilder sb = new StringBuilder("Hi ");

sb.Append(Name);

sb.Append(", the Cache entry was made at ");

sb.Append(System.DateTime.Now.ToString());



return(sb.ToString());

Cannot resolve collation conflict for column 2 in SELECT statement

In MS SQL SERVER, the collation can be set in column level. When compared 2 different collation column in the query, this error comes up. Following article gives you details on fixing the collation problems.

http://blog.sqlauthority.com/2007/06/11/sql-server-cannot-resolve-collation-conflict-for-equal-to-operation/

In addition select statement can also be a cause for the above problem

E.g.
SELECT  P.ID,P.PASSENGER_NAME  +' '+ISNULL(P.LAST_NAME,'')  [PASSENGER_NAME],P.BAG_COUNT 
    FROM am.PASSENGER P

In the above table both PASSENGER_NAME and LAST_NAME columns has datatype of nvarchar(50). When I ran the above query the collation conflict error occured and following way I was able to fix it.


SELECT  P.ID,
P.PASSENGER_NAME  +' '+ISNULL(P.LAST_NAME,'')  COLLATE DATABASE_DEFAULT [PASSENGER_NAME],
P.BAG_COUNT 
    FROM am.PASSENGER P

Preventing Users From Copying Text From and Pasting It Into TextBoxes

Many websites that support user accounts require users to enter an email address as part of the registration process. This email address is then used as the primary communication channel with the user. For instance, if the user forgets her password a new one can be generated and emailed to the address on file. But what if, when registering, a user enters an incorrect email address? Perhaps the user meant to enter me@example.com, but accidentally transposed the first two letters, entering em@example.com. How can such typos be prevented?

Calculating Date Difference in C#

The direct and simplest way to achieve this is by using the Microsoft.VisualBasic namespace and invoking the DateDiff method.

E.g.
long nYears = Microsoft.VisualBasic.DateAndTime.DateDiff(Microsoft.VisualBasic.DateInterval.Year, dt, dtNow, Microsoft.VisualBasic.FirstDayOfWeek.System, Microsoft.VisualBasic.FirstWeekOfYear.System);

There are some arguments over using this. Have look at the following link.
http://www.c-sharpcorner.com/UploadFile/DipalChoksi/DateDiff_CS_DC09132006172429PM/DateDiff_CS_DC.aspx

Microsoft Net.Framework 3.5 is necessary for launch the prog

Instructions :

1.) Disable Kaspersky's 'Self-Defense' feature and finish your kaspersky product before download Kaspersky trial resetter ( because it's a false positive )

Find the control inside the contenttemplate of the device specific?

In my mobile application i wanted to find a control that was in a devicespecific tag. I am surprised there was no dirac way to find that control and following work-around solved my issue.

public Control GetControl(string ID, Control cstart)
    {
        Control co = new Control();
        Type t = typeof(System.Web.UI.MobileControls.TemplateContainer);
        if (cstart.HasControls())
        {
            foreach (Control c in cstart.Controls)
            {
                if (co != null)
                {
                    if (t.IsInstanceOfType(c))
                    {
                        co = c.FindControl(ID);
                    }
                    else
                    {
                        if (c.HasControls())
                        {
                            co = GetControl(ID, c);
                        }
                    }
                }

            }
        }

        return co;
    }

If you want to find a dropdownlist named "ddlItems" inside devicespecific tag use

DropDownList ddl= (DropDownList)GetControl("ddlItems",this );

I am still searching for a simpler way to do this. In the time hope this will help in some way.

Enable/Disable Internal Webpage Scrollbar

To set the scrollbar for an elemnt with a web page You can try the "overflow" property in CSS/styles.

<div style="overflow:auto">...content...</div>

If you have content that is larger than the box (in this case the DIV layer) where you place the links, there will be a scrollbar to scroll to the rest of the links.

If you set overflow:hidden the the scroll bar won't be displayed for the element.

error executing child request for chartimg.axd

{
  Manager=1,
  Lecturer=2,
  AdminOfficer=3
}

Here is the iteration of Enum
foreach ( int val in Enum.GetValues(typeof( Employee)) )
{
  strin text=Enum.GetName( typeof(Employee),val); // gets Manager,Lecturer....etc
   Console.WriteLine(text + " value" + val.ToString()); //val is the actual value in Enum 1.2....etc
}

Set tooltip at the controls like Checkbox list or list items ?

These controls doesn't have  a property to directly set a tool tip. In such cases following code can be useful

int i=0;

foreach (ListItem li in checkboxList.Items) {

 li.Attributes.Add("title","Tooltip " + i.ToString());
 i++;

Google Adsense Terminology

Page impression: A page impression is generated every time a user views a page displaying Google ads. We will count one page impression regardless of the number of ads displayed on that page. For example, if you have a page displaying three ad units and it is viewed twice, you will generate two page impressions and six ad unit impressions.

Clicks:# The number of times an ad was clicked on in the given reporting period.

Page CTR (Clickthrough Rate): The number of ad clicks divided by the number of impressions for the page of ads that appears when a link unit is clicked.

Page eCPM (Effective Cost Per Thousand Impressions): Calculated by dividing earnings by number of page impressions and multiplying. This makes it easier to compare multiple sites to see which are performing better.

Earnings: Total revenue earned to date. More detail about earnings is available in the AdSense Help Center.

Order By union

Unions are used to display joined results from two queries with the same list of fields.
Ex:
Select f1,f2 --f1,f2 are the fields
from tbl1 --table
where f1<1
union
Select f1,f2
from tbl1
where f1>1

If you want to order the displayed results you'd have definitely tried following way

Select f1,f2
from tbl1
where f1<1
order by f1
union
Select f1,f2
from tbl1
where f1>1
order by f1

Sadly this is not going to work. If you want to order the displayed results the above query should be modified as follows

SELECT * FROM
(
SELECT f1,f2
from tbl1
where f1<1
order by f1
union
SELECT f1,f2
from tbl1
where f1>1
order by f1
) A
ORDER BY f1,f2

Numeric Text box

I have seen many people asking about using a textbox that accepts only numbers. Here I am providing some thoughts on that. I have seen many solutions diffent people have provided. But for me none of them was satisfactory. eventhough most of the textboxes allow only numbers, text valu can be pasted from right clicking mouse buttton and past option.
The solution for that is disabling paste on mouse right cliking.
'this class 'disables paste on text box

Dim NewVal As String
NewVal = Mid(tb.Text, 1, tb.SelectionStart) & str & Mid(tb.Text, tb.SelectionStart + tb.SelectionLength + 1, Len(tb.Text))
'NewVal will contain the future value of the textbox, if we would let
' what user wanted to paste to actually paste there...
If IsNumeric(NewVal) Then
' The result will be a numeric value. So go ahead and paste it!
tb.SelectedText = str
End If
' We're done, so we exit the sub (not letting the default WndProc() to
' paste the original string user tried to paste.
Exit Sub
End If
End Select
