Difference between where and having clause

1. The WHERE clause specifies the criteria which individual records must meet to be selcted by a query. It can be used without the GROUP BY clause. The HAVING clause cannot be used without the GROUP BY clause.
2. The WHERE clause selects rows before grouping. The HAVING clause selects rows after grouping.
3. The WHERE clause cannot contain aggregate functions. The HAVING clause can contain aggregate functions.
 The HAVING clause allows you to filter the results of aggregate functions,
such as COUNT() or AVG() or SUM(), or MAX() or MIN(), just to name a few.
HAVING provides you a means to filter these results in the same query,
as opposed to saving the results of a WHERE clause SQL statement to a temporary table
and running another query on the temporary table results to extract the same results.

Create EXE or Setup File in .NET Windows Application

Setup projects allow you to create installers in order to distribute an application. The resulting Windows Installer (.msi) file contains the application, any dependent files, information about the application such as registry entries, and instructions for installation. When the .msi file is distributed and run on another computer, you can be assured that everything necessary for installation is included; if for any reason the installation fails (for example, the target computer does not have the required operating system version), the installation will be rolled back and the computer returned to its pre-installation state.

The following steps will gives the elegant guidance to create an exe or installer file.

1, Go to file menu > click Add > new project >now “Add New Project” dialog will appear.

2.Select the “Other Project Types” and click “Setup and Deployment” projects,Choose “Setup Project”give name project name in name text box finally click OK.

3.New project appear in solution explorer,for eg., you have give the name “MyEXE” file will be displays with given name.

4.Right click the MyEXE > go View > click “File System”

5.You can see the “File System on TargetMachine”under three folders
Application Folder
User’s Desktop
User’s Program Menu

6.Select Application Folder and right click Add>Project Output>select Primary output

7. Select User’s Desktop richt click on the second window>click create new shortcut>select output file from Application folder>change the file name from primary output name to MyEXE

next >>


same procedure follows the user’s program menu also

8.If you want to change the Manufactures name for exe,just right click the project go to properties

change the properties as per you requirement
9.Finally Build the new project After successfully Build the project myEXE(Setup) will be appear in Application Debug or Release folder(depend upon the properties settings)

EXE or installer will be available on his physical path…

When you want to install the EXE on the client machine,you should be installed .NET Framework on that machine because, Applications and controls written for the .NET Framework v2.0 requires the .NET Framework Redistributable Package version 2.0 to be installed on the computer where the application or control runs.

What is the difference between a property a method and an event? Give an example of each

1. Text1.color ------ is a property  

2. Text1.text   ------- is Method     
3. button 1. Click  -- is an event

What is the difference between a property a method and an event? Give an example of each.  

*Property are a type of method that shows state of an Object 
like Caption, backcolour  etc.
*Methods/Functions are for changing Or doing something on 
the Object Like Move,Remove, Add etc.
*Event are Objects which means that something happend for 
which the object must respond to. And for this very reason 
we write method like 
button1_Click( sender Object, event Object)
The event Object(Delegate) is related with the method of 
that responder Object(Button)
