Response.Redirect Vs Server.Transfer

Server.Transfer: Transferring to another page using Server.Transfer conserves server resources. The transfer takes place on the server instead of forcing the browser to redirect to a new page. This means fewer HTTP requests coming through and can make your applications run more efficiently. Server.Transfer maintains to original URL in the browser.

Note:Only data transferred to a second ASP page are the ASP built-in objects and the ASP Error object values from the first request. Any variables declared by the first ASP page are not available in the second ASP page.

Server.Transfer has several advantages over Response.Redirect:
1) Because it saves a round trip between the server and the browser it's faster and reduces the load on the Web server.
2) The Response querystring and form collections are preserved during the transfer. As a result, you don't need to worry about reposting form and querystring data to the new page.

However, Server.Transfer does have a few disadvantages:

1) You can only use Server.Transfer to redirect to a page on the same Web server.
2) You can't pass a querystring to the new page. (However, remember that the querystring passed to the page executing the transfer will automatically be passed along to the new page.) If you try to pass a querystring to the new page, you will trigger an ASP error.
3) The browser is never notified of the new page, which can cause problems with relative links in some cases.
Note: Please 3rd point to noted very carefully

VBScript - ByVal Vs ByRef

Passing Parameters ByRef and ByVal

In VBScript, there are two ways values can be passed:
1) ByVal

2) ByRef

Using ByVal, we can pass arguments as values whereas with the use of ByRef, we can pass arguments are references.
ByVal:

the parameter is passed by value, thus the subroutine works with a copy of the original.
ByRef:

the parameter is passed by reference, thus the subroutine works directly with the original.

Example: Parameters By Value

Function GetValue( ByVal var )
var = var + 1
End Function

Dim x: x = 5

'Pass variable x to GetValue function ByVal
GetValue x

Response.write "x = " & x

Output: x = 5


Example: Parameters By Reference:


Function GetReference( ByRef var )
var = var + 1
End Function

Dim x: x = 5

'Pass the variable x to the GetReference function ByRef
GetReference x

Response.write x

Output: 6

Create Array in New Style Using VB Script / Java Script

Now we can create Array in modern style in VB script and JavaScript also, using this way we can reduce line of code, to make our program efficiency. For Example:
Create Array in JavaScript:

Var NakshtraName
NakshtraName = new Array("Ashwini", "Bhairini", "Krittika", "Rohini", "Mrigashirsha", "Aardhra", "Punarvasu", "Pushya", "Ashlesha", "Magha", "Purva Phalguni", "Uttara Phalguni", "Hastha", "Chitra", "Swati", "Vishaka", "Anuradha", "Jyestha", "Moola", "Purva Ashadha", "Uttara Ashadha", "Shravana", "Dhanista", "Shathabhisha", "Purva Bhadrapad", "Uttara Bhadrapada", "Revati");

Create Array in VB Script:

Dim NakshtraName

NakshtraName = Array("Ashwini", "Bhairini", "Krittika", "Rohini", "Mrigashirsha", "Aardhra", "Punarvasu", "Pushya", "Ashlesha", "Magha", "Purva Phalguni", "Uttara Phalguni", "Hastha", "Chitra", "Swati", "Vishaka", "Anuradha", "Jyestha", "Moola", "Purva Ashadha", "Uttara Ashadha", "Shravana", "Dhanista", "Shathabhisha", "Purva Bhadrapad", "Uttara Bhadrapada", "Revati")

environments, including Web client scripting in Microsoft IE version 3.0 and Web server scripting in Microsoft Internet
Information Server version 3.0.

Class, refers to any object that you create using the Class ... End Class statement.
Class User
' declare private class variable
Private m_userName
' declare the property
Public Property Get UserName
UserName = m_userName
End Property
Public Property Let UserName (strUserName)
m_userName = strUserName

7. What is Dictionary object?
The Dictionary object are those objects who stores name and value in pairs in an array. Value pairs means key and item
Write the below code in a notepad and save it with .vbs extension and run it from
Command Prompt.

Beers.Add "a", "Strauss"
Beers.Add "b", "Kingfisher"
Beers.Add "c", "Budweiser"
Msgbox ("The value corresponding to the key 'b' is " & wine.Item("b"))
Dictionary object properties:Count, Item, CompareMode etc.
Dictionary object methods:Exists, Add,Keys etc.

11. What is difference between VBScript and VBA?
Visual Basic is a standalone tool for creating separate
software components such as executable programs, COM
components and ActiveX? Controls. It is useful when

an existing application and is the best option for
customising software that already meets most needs.
VBScript is a lightweight version of the Visual Basic
language designed specifically for use on web pages. While
VBScript can sometimes be used for simple automation, VBA
is the premier technology designed specifically for
application automation.

Basic of Canvas Element in HTML5

HTML5 Canvas

Canvas element is useful for draw graphics on a web pages. With the help of canvas element we can draw rectangular area, and also control each and every pixels. It have various methods to draw any graphics.
Whenever we are going to draw any graphics first of all we should create Canvas element like:
< canvas id="CanvasID" width="100" height="100">< /canvas>
Canvas element have no drawing capability. So we must be done it in javaScript method like:

< script type="text/javascript">
var canId=document.getElementById("CanvasID");
var cantext= canId.getContext("2d");
cantext.fillStyle="#FF0000";
cantext.fillRect(0,0,180,95);
< /script>
Basically JavaScript uses id to find the canvas element:

Classic ASP Objects Part 1

Classic ASP Object:

Response Object:
Basicaly we are using ASP Response object to send output to the user from the server.
response.write alternate syntax <%= %>
Example:

<% response.write("Hello New Programmer...!") %>.
Method for Response Object

1)AddHeader:- Adds HTTP header abd HTTP response

2)AppendToLog:- Adds a string to the end of the server log entry

3)BinaryWrite:- Writes data, without any character conversion

4)Clear:- Clears any buffered HTML output

5)End :- Stops the current processing a script.

6)Flush:- Sends buffered output immediately

7)Redirect:- Redirects the user to a different URL intrire a application

8)Write:- Writes a specified string

Request Object:

Request Object:
Request object is used to get information from a user or visiter.
There are various collection for Request Objects:
Requesr.form("name")
Request.QueryString("name")
Request.cookies("cookiesname")
Request.ServerVariables (server_variable)
There are only ine method for Request object
BinaryRead : Retrieves the data sent to the server from the client.
<% dim a,b a=Request.TotalBytes b=Request.BinaryRead(a) %>

ASP Application Object:

ASP Application Object:

The Application object holds information that will be used by many pages in the application (like database connection information). The information can be accessed from any page. The information can also be changed in one place, and the changes will automatically be reflected on all pages.

<% Dim DailyHoroscope Application("DailyHoroscope")="Good day filled with happiness. All commitments and financial transactions need to be handled carefully. A lack of communication with someone you care will leave you depressed. tree in autumn. If travelling make sure you carry all-important documents. " Response.write(Application("DailyHoroscope")) %>

ASP Session Object:

Session Object: The Session object stores information about a user. session is logicaly objects to preserve data accross subsequence HTTP request.
<% Session("username")="Deepak madheshiya" Session("age")=24 %>

Checking for Browser Support HTML 5

Checking for Browser Support

Before you use the canvas element, make sure there is support in the browser or not. Using this way, you can provide some alternate text in case there is no support in their antique browser.
Example:
try {
document.createElement("canvasId").getContext("2d");
document.getElementById("browsersupport").innerHTML =
"Wow… HTML5 Canvas is supported in your browser.";
} catch (e) {
document.getElementById("browsersupport ").innerHTML = "Sorry… HTML5 Canvas is not supported
in your browser.";
}

In this example, you try to create a canvas object and access its context. If there is an error, you will
catch it and know that Canvas is not supported. A previously defined support element on the page is
updated with a suitable message to reflect whether there is browser support or not.
This test will indicate whether the canvas element itself is supported by the browser. It will not
indicate which capabilities of the Canvas are supported. At the time of this writing, the API is stable and
well-supported, so this should generally not be an issue to worry about.
