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:
Str="Welcome to the World of QTP" Print Len(Str) ' Output --> 27 Print Len("Good Morning") ' Output--> 12
⇒LCase Function
LCase: Returns a string that has been converted to lowercase.
Syntax: LCase(string)
Aruguments:
String: | Any valid string expression. If string contains Null, Null is returned. |
Example:
Str="Welcome to the World of QTP" Print LCase(Str) 'Output --> welcome to the world of qtp 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:
Str="Welcome to the World of QTP" Print Ucase(Str) 'Output --> WELCOME TO THE WORLD OF QTP 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:
⇒Right Function
Str="Welcome to the World of QTP" print Left(Str,3) 'Output --> Wel 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:
⇒Mid Function
Str="Welcome to the World of QTP" print Right(Str,12) 'Output --> World of QTP Print Right("Good Morning",7) 'Output --> Morning
⇒Mid Function
Mid: Returns a specified number of characters from a string.
Syntax: Mid(string, start[, length])
Aruguments:
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. |
Example:
⇒Replace Function

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. |
Example:
⇒Space Function
Str="Welcome to the World of QTP" print Replace(Str, "to","into") 'Output --> Welcome into the World of QTP Print Replace("Good Morning","Morning","Night") 'Output --> Good Night Print Replace("Quick Test ProfeSsional","s","x",5,3,0) 'Output --> k Text ProfeSxional Print Replace("Quick Test ProfeSsional","s","x",5,3,1) 'Output --> k Text Profexxional
⇒Space Function

Arguments:
number: | number of spaces you want in the string. |
Example:
⇒Split Function

⇒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:
⇒StrComp Function
'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. |

'InStr Print Instr(1, Str, "DO", 1) 'Output--> 5 , which means it found the string in 5th position for textual comparison Print Instr(1, Str, "DO", 0) 'Output--> 12 , which means it found the string in 12th position for binary comparison Print Instr(6, Str, "do", 0) 'Output--> 0 , which means it didnot found the string after the 6th position for binary comparison
⇒InStrRev Function
InStrRev: Returns the position of an occurrence of one string within another, from the end of string.
Syntax: InStrRev(string1, string2[, start[, compare]])
Arguments:
string1: | (Required) String expression being searched. |
string2: | (Required) String expression being searched for. |
start: | (Optional) Numeric expression that sets the starting position for each search. If omitted, -1 is used, which means that the search begins at the last character position. If start contains Null, an error occurs. |
compare: | (Optional) Numeric value indicating the kind of comparison to use when evaluating substrings. If omitted, a binary comparison is performed. |
Example:
Str="How do you DO ?" 'InStrRev Print InStrRev(Str,"DO",-1,1) 'Output--> 12 , which means it found the string in 12th position for textual comparison Print InStrRev(Str,"do",-1,0) 'Output--> 5 , which means it found the string in 5th position for binary comparison Print InStrRev(Str,"DO",13,0) 'Output--> 12 , which means it found the string in 12th position for binary comparison Print InStrRev(Str,"DO",10,1) 'Output--> 5 , which means it found the string in 5th position for textual comparison
