Reading BLOBs from SQL Server and 
display it in a Windows Form PictureBox
To convert from memorystream blob to bmp image:
private void PictureFormat(object sender, ConvertEventArgs e)
{
    // e.Value is the original value
    Byte[] img = (Byte[])e.Value;
    MemoryStream ms = new MemoryStream();
    int offset = 78;
    ms.Write(img, offset, img.Length - offset);
    Bitmap bmp = new Bitmap(ms);
    ms.Close();
    // Writes the new value back
    e.Value = bmp;
}

Read / Write BLOBs from / to SQL Server using C# .NET DataReader
Command.ExecuteReader method has an overload which will take a
CommandBehavior argument to modify the default behavior of the
DataReader. You can pass CommandBehavior.SequentialAccess to the
ExecuteReader method to modify the default behavior of the DataReader
so that instead of loading rows of data, it will load data
sequentially as it is received. This is ideal for loading BLOBs or
other large data structures. Note that this behavior may differ
depending on your data source.
= SequentialAccess Provides a way for the DataReader to handle rows that
contain columns with large binary values BLOBs. Rather than loading
the entire row, SequentialAccess enables the DataReader to load data
as a stream
= When accessing the data in the BLOB field, use the GetBytes or
GetChars typed accessors of the DataReader, which fill an array with
data.

%%const
- make reference parameter not change
- function that does not change object
- return value is const and cannot be changed

%%constructor

see destructor 
constructor function must have the same name as the class, and cannot
have any return type; not even void.

default constructor has no arguments, unless you define any
constructor, in which case the default is not provided. 

also default: the copy constructor, the copy assignment operator, and
the default destructor.

CRectangle::CRectangle (int a, int b) {
  width = a;
  height = b;
}

%%copy constructor

//make new object as copy of another
//if shallow copy works, you don't need copy constructor
Person q("Mickey"); // constructor is used to build q.
Person r(p);        // copy constructor is used to build r.
Person p = q;       // copy constructor is used to initialize in declaration.

Point::Point(const Point& p) {

}


%%destructor

The destructor must have the same name as the class, but preceded with
a tilde sign (~), no value.

  pair  myfloats (100.0,75.0);
  cout << myints.module() << '\n';
  cout << myfloats.module() << '\n';
  return 0;

The specialization is part of a template, for that reason we must
begin the declaration with template <>. And indeed because it is a
specialization for a concrete type, the generic type cannot be used in
it and the first angle-brackets <> must appear empty. After the class
name we must include the type that is being specialized enclosed
between angle-brackets <>.

general namespace. In order to access these variables from outside the

%%expression tree

http://msdn.microsoft.com/en-us/library/bb397951.aspx

Expression trees represent code in a tree-like data structure, where
each node is an expression, for example, a method call or a binary
operation such as x %lt y.

You can compile and run code represented by expression trees. This
enables dynamic modification of executable code, the execution of LINQ
queries in various databases, and the creation of dynamic queries.

In .NET Framework 4, the expression trees API also supports
assignments and control flow expressions such as loops, conditional
blocks, and try-catch blocks. By using the API, you can create
expression trees that are more complex than those that can be created
from lambda expressions by the C# and Visual Basic compilers. The
following example demonstrates how to create an expression tree that
calculates the factorial of a number.

// Creating a parameter expression.
ParameterExpression value = Expression.Parameter(typeof(int), "value");

// Creating an expression to hold a local variable. 
ParameterExpression result = Expression.Parameter(typeof(int), "result");

// Creating a label to jump to from a loop.
LabelTarget label = Expression.Label(typeof(int));

// Creating a method body.
BlockExpression block = Expression.Block(
    // Adding a local variable.
    new[] { result },
    // Assigning a constant to a local variable: result = 1
    Expression.Assign(result, Expression.Constant(1)),
    // Adding a loop.
        Expression.Loop(
    // Adding a conditional block into the loop.
           Expression.IfThenElse(
    // Condition: value > 1
               Expression.GreaterThan(value, Expression.Constant(1)),
    // If true: result *= value --
               Expression.MultiplyAssign(result,
                   Expression.PostDecrementAssign(value)),
    // If false, exit the loop and go to the label.
               Expression.Break(label, result)
           ),
    // Label to jump to.
       label
    )
);

// Compile and execute an expression tree.
int factorial = Expression.Lambda>(block, value).Compile()(5);

Console.WriteLine(factorial);
// Prints 120

%%lamda expression

    int j = myDelegate(5); //j = 25

    int oddNumbers = numbers.Count(n => n % 2 == 1);

%%abstract class vs interface


link
Good post by Mangesh Pote Associate Technology Level 2 @ Sapient from linked in

Interface is a contract for the client i.e. user of a class. This
class has implemented an interface.

Abstract class is a class which has defined as well as non-defined
members(functions/properties etc).

The members which are non-defined should be preceded with 'abstract'
keyword and so the class must be declared as abstract. Abstract class
is a class that has no direct instances, but whose descendants may
have direct instances.

Variables can be declared in abstract class, it is not allwed in
interface. Interface contains only abstract members. Access modifiers
are not allowed for interface members. Bydefault interface members are
public virtual.

A class may inherit several interfaces but it can inherit only one
abstract class.

Abstarct class can have constructor, interface cannot have
constructor.

Abstract class is used as a root in inheritance hierarchy, whereas
interface can be mixed up with hierarchy at any place.

@@Scrum


http://www.sdtimes.com/content/SDTimesPDFEdition.aspx?File=sdtimes252.pdf

The Scrum Alliance lists four core principles based on 2001’s Agile
Manifesto:

• Individuals and interactions over processes and tools

• Completed functionality over comprehensive documentation

• Customer collaboration over contract negotiation

• Responding to change over following a plan

The ceremonies are:

• Sprint planning: The team meets with the product owner to prioritize
the work to be delivered during a sprint

• Daily scrum: The team meets each day to share struggles and progress

• Sprint reviews: The team demonstrates to the product owner what it
has completed during the sprint

• Sprint retrospectives: The team looks for ways to improve the
product and process

The artifacts are the product backlog, the sprint backlog and the
burndown chart.  The product backlog is a list of items that can be
added or deleted from the project at any time. The backlog is
prioritized, with highest-priority items worked on first. The
lowerpriority items are loosely defined but are revisited and refined
as they work their way up the priority list.

Section I: Are you doing iterative development?

• Iterations must be time-boxed to less than four weeks

• Software features must be tested and working at the end of each
iteration

• The iteration must start before the specification is complete

Section II: Are you doing Scrum?

• You know who the product owner is

• There is a product backlog prioritized by business value

• The product backlog has estimates created by the team

• The team generates burn-down charts and knows its velocity

• The are no project managers (or anyone else) disrupting the work of
the team

Here are a series of interview questions
http://blog.sqlauthority.com/2008/09/20/sql-server-2008-interview-questions-and-answers-complete-list-download/

http://www.geocities.com/xtremetesting/SQLinterviewQuestions.html

%%Delete / Truncate / Drop

Delete = deletes WHERE records
Truncate = delete all records, but keep empty table
Drop = destroy table, breaking any references to table

%%Inner Join

from
http://www.geocities.com/xtremetesting/SQLinte
rviewQuestions.html

4. Q. What kinds of joins do you know? Give examples.
   A. We have self join, outer joint (LEFT, RIGHT), , cross-join ( Cartesian product n*m rows returned)
Exp:
outer joint
SELECT Employee.Name, Department. DeptName 
FROM Employee, Department
WHERE Employee.Employee_ID = Department.Employee_ID;

cross-join
SELECT * FROM table1, table2;

self join
SELECT e1.name | |’    ‘ | | e2.ename FROM emp e1, emp e2 WHERE e1. emp_no = e2.emp_no;

The following summarizes the result of the join operations:
 The result of T1 INNER JOIN T2 consists of their paired rows where the
join-condition is true.
 The result of T1 LEFT OUTER JOIN T2 consists of their paired rows where
the join-condition is true and, for each unpaired row of T1, the
concatenation of that row with the null row of T2. All columns derived
from T2 allow null values.
 The result of T1 RIGHT OUTER JOIN T2 consists of their paired rows
where the join-condition is true and, for each unpaired row of T2, the
concatenation of that row with the null row of T1. All columns derived
from T1 allow null values.
The result of T1 FULL OUTER JOIN T2 consists of their paired rows and,
for each unpaired row of T2, the concatenation of that row with the null
row of T1 and, for each unpaired row of T1, the concatenation of that row
with the null row of T2. All columns derived from T1 and T2 allow null
values.


%%Join

JOIN TWO TABLES
SELECT lastname, firstname, tag, vehicles.class
FROM drivers, vehicles
WHERE drivers.location = vehicles.location
AND drivers.class = vehicles.class

Notice that in this example we needed to specify the source table for
the class attribute in the SELECT clause.  This is due to the fact
that class is unambiguous – it appears in both tables and we need to
specify which table’s column should be included in the query results.
In this case it does not make a difference as the columns are
identical and they are joined using an equijoin.  However, if the
columns contained different data this distinction would be critical.
Here are the results of this query:

lastname     FirstName      Tag         Class
--------     ---------      ---         -----
Baker        Roland         H122JM      Car
Smythe       Michael        D824HA      Truck
Jacobs       Abraham        J291QR      Car


JOIN MORE THAN TWO TABLES
http://databases.about.com/od/sql/a/multiple_joins.htm
could bring a third table into your query by extending the JOIN
statement as follows: 

SELECT lastname, firstname, tag, open_weekends
FROM drivers, vehicles, locations
WHERE drivers.location = vehicles.location
AND vehicles.location = locations.location
AND locations.open_weekends = 'Yes'

lastname firstname tag open_weekends
-------- --------- --- -------------
Baker Roland H122JM yes
Jacobs Abraham J291QR yes
Jacobs Abraham L990MT yes

This powerful extension to the basic SQL JOIN statement allows you to
combine data in a complex manner.

BCP

This is one of the options that is mostly widely used.  One reason for
this is that it has been around for awhile, so DBAs have come quite
familiar with this command.  This command allows you to both import
and export data, but is primarily used for text data formats.  In
addition, this command is generally run from a Windows command prompt,
but could also be called from a stored procedure by using xp_cmdshell
or called from a DTS or SSIS package.

Here is a simple command for importing data from file
C:\ImportData.txt into table dbo.ImportTest.

bcp dbo.ImportTest in 'C:\ImportData.txt' -T -SserverName\instanceName
For more information about bcp click here.

BULK INSERT This command is a T-SQL command that allows you to import
data directly from within SQL Server by using T-SQL.  This command
imports data from file C:\ImportData.txt into table dbo.ImportTest.

BULK INSERT dbo.ImportTest 
FROM 'C:\ImportData.txt' 
WITH ( FIELDTERMINATOR =',', FIRSTROW = 2 )
For more information about BULK INSERT click here.

OPENROWSET This command is a T-SQL command that allows you to query
data from other data sources directly from within SQL Server.  By
using this command along with an INSERT INTO command we can load data
from the specified data source into a SQL Server table.

This command will pull in all data from worksheet [Sheet1$]. By using
the INSERT INTO command you can insert the query results into table
dbo.ImportTest.

INSERT INTO dbo.ImportTest 
SELECT * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
'Excel 8.0;Database=C:\ImportData.xls', [Sheet1$])
Here is another example where data is pulled from worksheet [Sheet1$] by using a SELECT * FROM command. Again, by using the INSERT INTO command you can insert the query results into table dbo.ImportTest.   The query can be any valid SQL query, so you can filter the columns and rows by using this option.

INSERT INTO dbo.ImportTest 
SELECT * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
'Excel 8.0;Database=C:\ImportData.xls', 'SELECT * FROM [Sheet1$]')
For more information about OPENROWSET click here.

OPENDATASOURCE This command is a T-SQL command that allows you to
query data from other data sources directly from within SQL Server.
This is similar to the OPENROWSET command.

INSERT INTO dbo.ImportTest 
SELECT * FROM OPENDATASOURCE('Microsoft.Jet.OLEDB.4.0', 
'Data Source=C:\ImportData.xls;Extended Properties=Excel 8.0')...[Sheet1$]
For more information about OPENDATASOURCE click here.

OPENQUERY Another option is OPENQUERY.  This is another command that
allows you to issue a T-SQL command to select data and again with the
INSERT INTO option we can load data into our table.  There are two
steps with this process, first a linked server is setup and then
second the query is issued using the OPENQUERY command.  This option
allow you to filter the columns and rows by the query that is issued
against your linked data source.

EXEC sp_addlinkedserver 'ImportData', 
   'Jet 4.0', 'Microsoft.Jet.OLEDB.4.0', 
   'C:\ImportData.xls', 
   NULL, 
   'Excel 8.0' 
GO
INSERT INTO dbo.ImportTest 
SELECT * 
FROM OPENQUERY(ImportData, 'SELECT * FROM [Sheet1$]')

For more information about OPENQUERY click here.

Linked Servers
Here is yet another option with setting up a linked server and then issuing a straight SQL statement against the linked server.  This again has two steps, first the linked server is setup and secondly a SQL command is issued against the linked data source.

EXEC sp_addlinkedserver 'ImportData', 
   'Jet 4.0', 'Microsoft.Jet.OLEDB.4.0', 
   'C:\ImportData.xls', 
   NULL, 
   'Excel 8.0' 
GO
INSERT INTO dbo.ImportTest 
SELECT * FROM ImportData...Sheet1$

%%remote data base

LINKED DATA BASE
q: I'm trying to copy data from one table on a remote database to my
local database. I'm using sql 2005 management studio express.
I'm looking for an example that uses t-sql to select the data from
the remote table into the local table.


a: IF you have the remote server set up as a 'LINKED SERVER' (see
Books Online: Linked Servers), you can use a query similar to this one:
 
INSERT INTO MyLocalTable
 
   (  Column1,
 
      Column2,
 
      {etc}
 
   )
 
   SELECT 

      Column1,
 
      Column2,
 
      {etc}
 
   FROM MyLinkedServer.RemoteDatabase.dbo.RemoteTable
 
   WHERE {any filter criteria goes here}


source: 
http://social.msdn.microsoft.com/forums/en-US/transactsql/thread/b00b25c5-6df7-4b2a-a2df-e9a089ecc68e

LINKED SERVER
You can add linked server and use it to copy the table data across server.
Creating linked server is done using sp_addlinkedserver:

EXEC sp_addlinkedserver 'RemoteServer', N'SQL Server'

Based on security settings you may need to map remote server logins. This is
done using sp_addlinkedsrvlogin:

EXEC sp_addlinkedsrvlogin 'RemoteServer', 'false', 'LocalUser',
'RemoteUser', 'RemotePassword'

Then you just run a normal query referencing the linked server table with 4
part name:

INSERT INTO TargetTable
SELECT 
FROM RemoteServer.RemoteDB.dbo.RemoteTable

If you can set up a linked server the other way around (from your remote
server to the local server), then executing the query on the remote server
will have no problems setting IDENTITY_INSERT ON. The option cannot be set
permanently and it has to be set in the same session as the INSERT
statement.

Alternative is to use BCP or Bulk Insert to insert the data which have
option to keep identity.

MUTEX WORK ACROSS PROCESS, TIMEOUT, NOTIFY ON ABANDON
CRITICAL SECTION IS FASTER
http://www.microsoft.com/msj/archive/S1DA0.aspx
- mutexes can synchronize threads across process boundaries, you can
wait on a mutex by specifying a timeout value, and mutexes notify a
thread when they are abandoned.
- critical sections are faster.
Mutex objects are kernel objects and as such the functions that
manipulate them (WaitForSingleObject and ReleaseMutex) require the
transition from user mode to kernel mode.

%%Semaphore

Win32 supports two types of semaphores: mutual exclusion (mutex) and
counting. A semaphore is a resource that contains an integer value.
Semaphores allow synchronization of processes by testing and setting
the integer value in a single atomic operation.

A semaphore is similar to a mutext, except that it involves a state of
signaled or not signaled.  

A counted semaphore is a semaphore with a signal count. Typically this
involves a semaphore and a count.  So if you have a limited resource
of say five items, you allow threads to get exclusive control of the
item for upto 5 threads. The 6th thread will block waiting to get
access. When one of the other users of the resource releases it, then
the waiting thread will get it.

a binary semaphore is better known as a mutex
