[.net] use keyword "as" to cast object in C#

here is the piece of code:

// Put user code to initialize the page here
// add login module dynamicly
//control1 = LoadControl("Modules\\Login\\Login.ascx");

Frame based lay out can be instead by using "user control"

Create user controls as different components and place them on the form in default.aspx. These user controls can be orginized by using table.

compare package in Java and C#

From

http://www.ondotnet.com/pub/a/dotnet/2001/06/07/csharp_java.html?page=3


Conceptually, Java packages are the same as .NET namespaces. However, implementations are different. In Java, package names are also a physical thing that determines the directory structure where your .java files must reside. In C#, there is a complete separation between physical packaging and logical naming, so the name for your namespace has nothing to do with the physical packaging. In C#, each source file can contribute to multiple namespaces and can take multiple public classes.

The physical packaging in .NET is called assembly. Each assembly contains a manifest that enumerates the files that are contained in the assembly, controls what types and resources are exposed outside the assembly, and maps references from those types and resources to the files that contain the types and resources. Assemblies are self-contained and an assembly can be contained in a single file or be split among a number of files. This packaging mechanism solves the problem with DLL files, notoriously known as DLL Hell.

Checkpoints: Use Case

(Copy from RUP. IBM)
Is each concrete use case involved with at least one actor? If not, something is wrong; a use case that does not interact with an actor is superfluous, and you should remove it. For more information, see Guidelines: Use Case.
Is each use case independent of the others? If two use cases are always activated in the same sequence, you should probably merge them into one use case.
For an included use case: does it make assumptions about the use cases that include it? Such assumptions should be avoided, so that the included use case is not affected by changes to the including use cases.
Do any use cases have very similar behaviors or flows of events? If so - and if you wish their behavior to be similar in the future - you should merge them into a single use case. This makes it easier to introduce future changes. Note: you must involve the users if you decide to merge use cases, because the users, who interact with the new, merged use case will probably be affected.
Has part of the flow of events already been modeled as another use case? If so, you can have the new use case use the old one.
Is some part of the flow of events already part of another use case? If so, you should extract this subflow and have it be used by the use cases in question. Note: you must involve the users if you decide to "reuse" the subflow, because the users of the existing use case will probably be affected.
Should the flow of events of one use case be inserted into the flow of events of another? If so, you model this with an extend-relationship to the other use case.
Do the use cases have unique, intuitive, and explanatory names so that they cannot be mixed up at a later stage? If not, you change their names.
Do customers and users alike understand the names and descriptions of the use cases? Each use-case name must describe the behavior the use case supports.
Does the use case meet all the requirements that obviously govern its performance? You must include any (nonfunctional) requirements to be handled in the object models in the use-case Special Requirements.
Does the communication sequence between actor and use case conform to the user's expectations?
Is it clear how and when the use case's flow of events starts and ends?
Behavior might exist that is activated only when a certain condition is not met. Is there a description of what will happen if a given condition is not met?
Are any use cases overly complex? If you want your use-case model to be easy to understand, you might have to split up complex use cases.
Does a use case contain disparate flows of events? If so, it is best to divide it into two or more separate use cases. A use case that contains disparate flows of events will be very difficult to understand and to maintain.
Is the subflow in a use case modeled accurately?
Is it clear who wishes to perform a use case? Is the purpose of the use case also clear?
Are the actor interactions and exchanged information clear?
Does the brief description give a true picture of the use case?

[SQL] use Information Schema Views

In SQL Server, we can use information schema Views to get meta information about tables.
Such as, to get the number of columns:

SELECT count(column_name)
FROM Information_Schema.Columns
WHERE Table_Name = 'Projects'

[SQL]Use variable in FROM clause in SQL Server

Problem: Try to implement:
Declare @tbName text
SELECT * FROM @tbName;

That will cause error. The soluthion is using dynamic SQL:

EXEC ( 'SELECT * FROM ' + ' " ' + @tbName + ' " ')

Put double quote to prevent the table name contains space.

Stored Procedure and SQL query:

CREATE PROCEDURE titles_cursor @titles_cursor CURSOR VARYING OUTPUT
AS
SET @titles_cursor = CURSOR
FORWARD_ONLY STATIC FOR
SELECT name
FROM sysobjects
WHERE xtype = 'U'
ORDER BY name

OPEN @titles_cursor
GO

--------------
use "Capital Improvement Projects"
GO

DECLARE @MyCursor CURSOR

EXEC titles_cursor @titles_cursor = @myCursor OUTPUT
DECLARE @tbName VARCHAR(200)
FETCH NEXT FROM @MyCursor INTO @tbName

WHILE (@@FETCH_STATUS = 0)
BEGIN
PRINT 'SELECT * AS '+'"'+@tbName+'" '+' FROM ' + @tbName
EXECUTE ('SELECT COUNT(*) AS '+'"' + @tbName+ '" ' + ' FROM ' + '"' + @tbName + '"')
FETCH NEXT FROM @MyCursor INTO @tbName
END
CLOSE @MyCursor
DEALLOCATE @MyCursor
