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 / 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.
