Byval refers to the actual value of the variable. ByRef
refers to the location of where the value is stored.
Passing.

Answer / sagar mitra

ByRef refers to the location, ByVal refers to the actual value. Also, if you are passing parameters with "ByVal" then even if the parameter values are changed, the original argument values will remain intact. But if you pass using "ByRef" then if the parameter values are changed, then the original argument value is also modified

Answer / akshitha

is passed & if the value of that argument is modified within
that method,orginal argument is not modified

byref-when a method is called by reference & an argument is
passed & if the value of that argument is modified within
that method,original argument is modified

Answer / manjunathareddy

ByVal :- Byval is address the actual value of the variable.

Ex:- Function abc(Byval var)
var=var+1
End Function

Dim x:x=2
abc x
Msgbox x

In Above example 2 is the Actual value so it address the
actual value,the Result is 2.

ByRef:- ByRef is address the Location of the Stored variable.

Function abc(ByRef var)
var=var+1
End Function

Dim x:x=2
abc x
Msgbox x

In above example it 2 actual value but in byref it refers
the location of the stored variable the result is 3.

Answer / fgf

Small correction: we have to call the function

Function abc(ByRef var)
var=var+1
End Function

Dim x:x=2
Call abc(x)
Msgbox x
