concatenation, string, string compare in qtp, string comparison in qtp, String Functions, string manipulation in qtp



String Functions
Len Function
Len : Returns the number of characters in a string or the number of bytes required to store a variable.
 Syntax: Len(string | varname)

 Arguments:
 string:  Any valid string expression. If string contains Null, Null is returned.
Varname:  Any valid variable name. If varname contains Null, Null is returned.

Example yu:
1.       Str="Welcome to the World of QTP"
Print Len(Str)         
' Output --> 27

2.       Print  Len("Good Morning") 
' Output--> 12
________________________________________
LCase Function
LCase: Returns a string that has been converted to lowercase.
 Syntax: LCase(string)

 Arguments:
 String:  Any valid string expression. If string contains Null, Null is returned.

 Example:
1.       Str="Welcome to the World of QTP"
Print LCase(Str)
'Output --> welcome to the world of qtp

2.       Print  Lcase("Good Morning")  
'Output --> good morning
________________________________________
UCase Function
Ucase : Returns a string that has been converted to uppercase.
 Syntax: UCase(string)

 Arguments:
 String:  Any valid string expression. If string contains Null, Null is returned.

 Example:
1.       Str="Welcome to the World of QTP"
       Print Ucase(Str)
      'Output --> WELCOME TO THE WORLD OF QTP

2.       Print  Ucase("Good Morning")             
       'Output --> GOOD MORNING
________________________________________
Left Function
Left: Returns a specified number of characters from the left side of a string.
Syntax: Left(string, length)

 Arguments:

 String:  String expression from which the leftmost characters are returned. If string contains Null, Null is returned.

length:  Numeric expression indicating how many characters to return. If 0, a zero-length string("") is returned. If greater than or equal to the number of characters in string, the entire string is returned.

 Example:

1.       Str="Welcome to the World of QTP"
print  Left(Str,3)                                                  
'Output --> Wel

2.       Print Left("Good Morning",4)                             
'Output --> Good
________________________________________
Right Function
Right: Returns a specified number of characters from the right side of a string.
 Syntax: Right(string, length)

 Arguments:

 String:  String expression from which the rightmost characters are returned. If string contains Null, Null is returned.

length: Numeric expression indicating how many characters to return. If 0, a zero-length 
string is returned. If greater than or equal  to the number of characters in string, the entire string is returned.

 Example:

1.       Str="Welcome to the World of QTP"
print  Right(Str,12)                                               
'Output --> World of QTP

2.       Print Right("Good Morning",7)                                           
'Output -->  Morning
________________________________________
Mid Function
Mid: Returns a specified number of characters from a string.
 Syntax: Mid(string, start[, length])

 Arguments:

 String:  String expression from which characters are returned. If string contains Null, Null is returned.

Start:     Character position in string at which the part to be taken begins. If start is greater than the number of characters in string, Mid returns a zero-length string ("").

length: Number of characters to return. If omitted or if there are fewer than length characters in the text (including the character at start), all characters from the start position to the end of the string are returned.

Replace Function
Replace: Returns a string in which a specified substring has been replaced with another substring a specified number of times.
 Syntax: Replace(expression, find, replacewith[, start[, count[, compare]]])

 Arguments:

 expression:  (Required) String expression containing substring to replace.

find: (Required) Substring being searched for.

replacewith: (Required) Replacement substring.

start: (Optional) Position within expression where substring search is to begin. If omitted, 1 is assumed. Must be used in conjunction with count.

count: (Optional) Number of substring substitutions to perform. If omitted, the default value is -1, which means make all possible substitutions. Must be used in conjunction with start.

compare: (Optional) Numeric value indicating the kind of comparison to use when evaluating substrings. See Settings section for values. If omitted, the default value is 0, which means perform a binary comparison.

Split Function
Split: Returns a zero-based, one-dimensional array containing a specified number of substrings.
 Syntax: Split(expression[, delimiter[, count[, compare]]])

 Arguments:

 expression: (Required) String expression containing substrings and delimiters. If expression is a zero-length string, Split returns an empty array, that is, an array with no elements and no data.

delimiter: (Optional) String character used to identify substring limits. If omitted, the space character (" ") is assumed to be the  delimiter. If delimiter is a zero-length string, a single-element array containing the entire expression string is returned.

count:   (Optional) Number of substrings to be returned; -1 indicates that all substrings are returned.

compare: (Optional) Numeric value indicating the kind of comparison to use when evaluating substrings.

 Example:

'Space as Delimiter
Str="Welcome to the World of QTP"
'Split
SArray=Split(Str," ",-1)
For  i= 0 to UBound(SArray)
    Print  SArray(i)
Next

'Comma As Delimitter
Str="Welcome,to,the,World,of,QTP"
'Split
SArray=Split(Str,",",-1)
For  i= 0 to UBound(SArray)
    Print  SArray(i)
Next

StrComp Function
StrComp: Returns a value indicating the result of a string comparison.
Syntax: StrComp(string1, string2[, compare])

 Arguments:

 string1: (Required) Any valid string expression.

string2: (Required) Any valid string expression.

compare:  (Optional) Numeric value indicating the kind of comparison to use when evaluating strings. If omitted, a binary comparison is performed.

 Example:

Str="Welcome to the World of QTP"
StrComp
Str1 = "QTP"
Str2 = "qtp"                                  
Print StrComp(Str1, Str2, 1)                          
'Output--> Returns 0 , which means Str1 is equal to Str2 for  textual comparison
Print StrComp(Str1, Str2, 0)                          
'Output--> Returns -1 , which means Str2 is  greater than  Str1 for  Binary comparison

Print StrComp(Str2, Str1)                              
'Output-->Returns 1, which means Str2 is  greater than  Str1 for  Binary comparison
Print StrComp(Str1, Str2)                                
'Output-->Returns -1, which means Str1 is  less than  Str2  for  Binary comparison

StrReverse Function
StrReverse: Returns a string in which the character order of a specified string is reversed.
 Syntax: StrReverse(string1)

 Arguments:
 string1: string whose characters are to be reversed. If string1 is a zero-length string (""), a zero-length string is returned. If string1 is Null, an error occurs.

Example:

Str="Welcome to the World of QTP"
StrReverse
print  StrReverse(Str)                                
'Output-->PTQ fo dlroW eht ot emocleW
