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;
}


http://www.akadia.com/services/dotnet_read_write_blob.html
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.

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 <>.

In this case, a and b are normal variables integrated within the general namespace. In order to access these variables from outside the namespace we have to use the scope operator ::. For example, to access the previous variables we would have to put:

%%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.

%%Interview Questions

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

%%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.

Visual Studio provides two kinds of templates:
•Project Template: This template will allows us to create a new
project based on the exported project. This template will be
accessible from New Project dialog window.
•Item Template: This template will allows us to add our exported item
as a part of their project.

Questions and Answers What is VxD?  A VxD, or Virtual Device Driver,
is a 32-bit multiplexing device driver that manages data exchanges
between Windows applications and system services.  It runs in ring
0 so it can execute any instruction, and it is more powerful than 
a DLL. You can use it to call a windows 3.0 or Win95 process from
DOS

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


@@Winforms

WinForms Data Validation Controls have validate event the
CausesValidation property set to true to another control that has the
CausesValidation property set to true, e.g. from a TextBox control to
the OK button. The Validating event gives the handler the chance to
cancel the move of focus by setting the CancelEventArgs.Cancel
property to true.

SOAP Implementations as Frameworks
SOAP, by itself, is about as useful as a paper envelope. That is, anything can be put inside, with no rules guiding the process.

There have been several initiatives to formalize certain parts of the SOAP specification to provide interoperability and reliable messaging.
