use the split and left function and if u dint get i il give 
the code

please write the code.

it is not possible

after R & D in Qtp i found the solution guys, use Instr() 
function is useful for find the text .

One method is 


a="Raju want to marry"
b="want"

if instr(1,a,b) then
    msgbox("Exists")
else
   msgbox("Does not exists")
end if

another method is 
use regular expression. this is a bit lengthy

var="Raju want to marry"
var1=InStr(1,var,"want")
if var1>0 then
  MsgBox "String Exists"
Else
  MsgBox "Doesn't Exists the String"

Exact Answare Replay me if possible on no1lmahesh@krify.com
var="raju want married"
var1=InStr(1,var,"want")
MsgBox var1
var2=Mid(var,var1)

MsgBox var2
var3=Left(var1,4)
MsgBox var3

n=InputBox("Enter name")
var=Split(n," ",-1,1)
nam=var(1)
msgbox nam

If  nam="want" Then
	Services.LogMessage nam,OutputMsg
	Else
	Services.LogMessage"Failed",OutputMsg
End If

It is also possible through Text Check Point.

can put exceptional handling as"* want *"
so it'll check for many char before & after want & by
putting text check point

yes preeti you are correct. you can use regular expression.
like "srinkv@gmail.com" if you want to check "srin" in the 
syntex it is "srin*" in vbscript & /srin*/ in jscript.

Agree with your comment

editbox_val="raju want married"
expected_val="want"
d=split(editbox_val," ")
   ( ...since d is an array....here d(0) contains "raju")
   ( ..here   d(1) contains "want")
   ( ...here d(2) contains "married")

 for i=0 to ubound(d)
     act_val=d(i)
      if (expected_val=act_val) then 
           msgbox "want is present - pass"
           exit for
       else 
           msgbox "fail - not present"
      end if 
 next

str="raju wants marriage"
a=instr(1,str,"wants")
If a<>0 Then
	msgbox "Required text existed "
	Else
	msgbox "Required text not existed"
End If

Hi mahesh,
Small correction!!!

var="raju want married"
var1=InStr(1,var,"want")
MsgBox var1
var2=Mid(var,var1)

MsgBox var2
var3=Left(var2,4)'you placed var1 i repaced var2
MsgBox var3

Hi Friends, Pls check this answer:

s= "raju want married"
d="want"
x= split (s," ")
if Instr(d,x(1))<> 0 then
	msgbox "Passed"
	else
	msgbox "Failed"
End If

Thanks,
Sri

This can be easily checked with the help of Text Area
Checkpoint as this checkpoint can check the particular
Text/String in the paragraph, particular area can be
selected and checked for the Text/String.
