Validation Controls in ASP.net
ASP.Net provides validation controls which a rich amount
of validation services that saves your work to make
java script code because at a huge level java script is used to validate client side
validation. for perform validation using java script you must have knowledge of
java script.
But you can perform powerful validation using ASP.net Validation
Controls with knowledge of java script..
RequiredFieldValidator Control
Evaluates the value of an input control to ensure that the user enters a value.
Use the RequiredFieldValidator control to make an input control a mandatory field. The input control fails validation if the value it contains does not change from its initial value when validation is performed. This prevents the user from leaving the associated input control unchanged. By default, the initial value is an empty string (""), which indicates that a value must be entered in the input control for it to pass validation.

Server Side code :

{
Label1.Text = "Running Server code";
}
RangeValidator Control
Evaluates the value of an input control to determine whether it is between the specified upper and lower boundaries.
The RangeValidator control allows you to check whether a user's entry is between a specified upper and a specified lower boundary. You can check ranges within pairs of numbers, alphabetic characters, and dates. Boundaries are expressed as constants.

Print a character in Notepad,Excel,Power Point using ASCII code
Notepad is windows platform text editor.
You can enter value in notepad within a ASCII range
but You can also provide input using ASCII code
because keyboard has not all key which can print all ASCII Code
Steps

How to make popup menu in VB 6.0
Hi...
Popup menu is menu which appeared when we right click from mouse
on a form. You can see it when you right click on desktop a menu appeared
which is pop menu.
There're many uses of popup menu in windows development
Popup menu provide many flexible option front of user its really make
an application more user friendly because user choose their option frequently
as you can see in image that you must make a menu and make it visible property false
otherwise it'll not appear on form.
You have to visible it on mouse right click . So we can use form mouse up event.
For Detect right click button of mouse you can use Button value which initialize by event handler
if button value is 2 then its rdenotes right click otherwise 1 if user clicked on left button
Now you can make its visibility true as in code....
Private Sub Form_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single)
If Button = 2 Then
PopupMenu mnedit
End If
End Sub

Tree Using Opration Using C language
Tree
a tree is a widely used data structure that simulates a hierarchical tree structure with a set of linked nodes.
A tree can be defined recursively (locally) as a collection of nodes (starting at a root node), where each node is a data structure consisting of a value, together with a list of nodes (the "children"), with the constraints that no node is duplicated. A tree can be defined abstractly as a whole (globally) as an ordered tree
Menu based program for tree operation (Add,Delete,inorder,preorder,postorder print).

Double Link List Using C Language
Double Link List..
a doubly linked list is a linked data structure that consists of a set of sequentially linked records called nodes. Each node contains two fields, called links, that are references to the previous and to the next node in the sequence of nodes. The beginning and ending nodes' previous and next links, respectively, point to some kind of terminator
Advantage
A doubly linked list can be traversed in both directions (forward and backward). A singly linked list can only be traversed in one direction.
A node on a doubly linked list may be deleted with little trouble, since we have pointers to the previous and next nodes. A node on a singly linked list cannot be removed unless we have the pointer to its predecessor.

A node on a doubly linked list may be deleted with little trouble, since we have pointers to the previous and next nodes. A node on a singly linked list cannot be removed unless we have the pointer to its predecessor.
On the flip side however, a doubly linked list needs more operations while inserting or deleting and it needs more space (to store the extra pointer).

Queue Using Single Link List Using C Language
Queue
a queue is a particular kind of abstract data type or collection in which the entities in the collection are kept in order and the principal (or only) operations on the collection are the addition of entities to the rear terminal position and removal of entities from the front terminal position. This makes the queue a First-In-First-Out (FIFO) data structure. In a FIFO data structure, the first element added to the queue will be the first one to be removed.

Stack Operation using C Language
Stack......
a stack is an area of memory that holds all local variables and parameters used by any function
One way of describing the stack is as a last in, first out (LIFO)
The push operation adds a new item to the top of the stack, or initializes the stack if it is empty
If the stack is full and does not contain enough space to accept the given item, the stack is then considered to be in an overflow state. The pop operation removes an item from the top of the stack. A pop either reveals previously concealed items, or results in an empty stack, but if the stack is empty then it goes into underflow state (It means no items are present in stack to be removed)

#include<stdio.h>
#include<conio.h>

Singal Link List Operation using C Language
In computer science, a linked listis a data structure consisting of a group of nodes which together represent a sequence. Under the simplest form, each node is composed of a datum and a reference (in other words, a link) to the next node in the sequence; more complex variants add additional links. This structure allows for efficient insertion or removal of elements from any position in the sequence.
#include<stdio.h>

Database operation ASP.net using SQL Server 2000
The ADO.NET architecture is designed to make life easier for both the application developer and the database provider. To the developer, it presents a set of abstract classes that define a common set of methods and properties that can be used to access any data source. The data source is treated as an abstract entity, much like a drawing surface is to the GDI+ classes.
Controls :
- Three Textbox
- Three Button
- One GridView
- SqlDataSource
Setting Gridview :
- Add Gridview select auto format if you want to use available style for gridview select a style click ok
- Choose data source select < New Data source.. >
- Select Database from Configuration Wizard
- Click New Connection and change database type from Add Connection wizard
- Choose SQL Server click ok
- Enter Server name I have have used . for local client server
- Select Database Click ok
