Introduction
VB has numerous built-in string functions for
processing strings. Most VB string-handling functions return a string, although
some return a number such as the Len function which returns the length of a
string and functions like Instr and InstrRev which return a character position
within the string. The functions that return strings can be coded with or
without the dollar sign ($) at the end, although it is more efficient to use the
version with the dollar sign. The String class of the .NET framework provides
many built-in methods to facilitate the comparison and manipulation of strings.
It is now a trivial matter to get data about a string or to create new strings
by manipulating current strings. The Visual Basic .NET language also has
inherent methods that duplicate many of these functionalists.
String operations in VB
- Comparison : Used to compare two string.
- Concatenation : Used to add two string.
- Containment : To find out if one string is
a substring of another use the InStr function.
- Indexing and Substrings : Strings can be
used almost as if they were lists of characters.
- String constants : String constants can be
declared like any other constant.
Example : Simple example
comparison of string in VB.
Code
Option Explicit
Dim strTom as
String
Dim strTom2 as String
strTom = "manish"
strTom2 = "manish"
If StrComp(strTom, strTom2) = 0 Then
Debug.Print
"The strings are the same.
