VB SCRIPT OPERATORS

Operator precedence

a=10+20*2

msgbox a '50

a=(10+20)*2

msgbox a '60

1) Arithmetic

a) ^ Exponentiation

b) * multiplication

c) / division

d) \ Integer division

e) Mod operator

f) + Addition

g) - subtraction

h) & concatenation

Example:

Dim a,b,c

a=10

b=3

c=a^b

msgbox c '1000

c=a*b

msgbox c '30

c=a/b

msgbox c '3.33333333

c=a\b

msgbox c '3

c=a mod b

msgbox c '1

c=a-b

msgbox c '7

Dim a,b,c

a=10

b=2

c=3

d=c*a^b

'c=a+b

msgbox d '1000

Addition (+) operator

Dim a,b,c

a=10

b=2

c=a+b

msgbox c '12  (if both are numeric, then it adds)

a="10"

b=2

c=a+b

msgbox c '12  (one is string another numeric, then it adds)

a="10"

b="2"

c=a+b

msgbox c '102 (if both are strings, then it concatenates)

a="hydera"

b="bad"

c=a+b

msgbox c 'hyderabad

a="gagan"

b=2

c=a+b

msgbox c 'error

Concatenation Operator

Dim a,b,c

a=10

b=2

c=a&b

msgbox c '102

a="10"

b=2

c=a&b

msgbox c '102

a="10"

b="2"

c=a&b

msgbox c '102

a="hydera"

b="bad"

c=a&b

msgbox c '102

2) Comparison Operators (have equal precedence)

a) =

b) <

c) <=

d) >

e) >=

f) <>

Example:

Dim a,b,c

a=10

b=2

c=a=b

msgbox c 'false

c=a<b

msgbox c 'false

c=a>b

msgbox c 'true

3) Logical (have equal precedence)

a) Not (Logical Negation)

If not window("Flight Reservation").Exist (3)  Then

SystemUtil.Run "D:\Program Files\HP\QuickTest Professional\samples\flight\app\flight4a.exe","","D:\Program Files\HP\QuickTest Professional\samples\flight\app\","open"

Dialog("Login").Activate

Dialog("Login").WinEdit("Agent Name:").Set "fsdfsf"

Dialog("Login").WinEdit("Password:").SetSecure "4bda42ce3f38c716e0de9aadc2cdb242d58a0d1d"

Dialog("Login").WinButton("OK").Click

End If

For ord= 1 to 5

Window("Flight Reservation").Activate

Window("Flight Reservation").WinButton("Button").Click

Window("Flight Reservation").Dialog("Open Order").WinCheckBox("Order No.").Set "ON"

Window("Flight Reservation").Dialog("Open Order").WinEdit("Edit").Set ord

Window("Flight Reservation").Dialog("Open Order").WinButton("OK").Click

Next

b) and (Logical conjunction)

          Exp 1 Exp2  Result

          True   True   True

          True   False  False

          False  True   False

          False  False  False

Dim a,b,c

a=100:b=20:c=30

If a>c and a>b Then

          msgbox "a is a big number"

          else

msgbox "a is Not a big number"

End If

c) or (Logical disjunction)

d) xor (Logical exclusion)
