addresses.
Variant:
If a variable data type is not specified in definition, VBA take it as Variant
data type variable. So it can store other data type values and stored as
16-byte data value
What is the default data type in VBA?
Variant
data type
What is the data type of Var1 and Var2 in below variable
definition?
Dim Var1, Var2, Var3 As Integer
Data type
of Var1 and Var2 is Variant

value for an Object data type variable in VBA is Nothing
What is the importance of Option Explicit statement in VBA?
Option
Explicit makes the declaration of variables mandatory in VBA. To make explicit
declaration of all variables mandatory, Option Explicit statement must appear
before any procedures at file level. Option Explicit ensures that all variables
are explicitly declared within that respective module and if an attempt is made
to use undeclared variable, compile time error occurs.
What is the use of Option Base statement in VBA?
Option
Base statement is used at module level. It declare the default lower bound for
Array subscripts. For example, if we use Option Base 1, it will make the
lower bound of each Array in that module to start from 1 instead of 0. Option
Base statement has no impact on ParamArray parameter type used in procedures or
functions. The array variable declared as a ParamArray has a lower bound value
of 0, regardless of Option Base statement setting at module level
Specify the difference between passing variables ByRef and ByVal?
If an
argument or variable is passed ByRef, it means a reference or memory
address of that argument is passed to the called procedure in that particular
case. If the value of the argument changes in the called procedure, the
modified value of that argument reflects in calling procedure.
If an
argument or variable is passed ByVal, it means actual value of variable is
passed to the called procedure in that particular case. If the value of the
argument changes in the called procedure, the modified value is only limited to
the called procedure and the new value does not reflects in calling procedure.
What is the default method of passing parameters in a procedure?
By
default, parameter is passed by reference i.e. ByRef.
Can we pass an Array by value (i.e. ByVal) to procedure?
No.
Arrays are always passed by reference.
What will happen if we try to pass an Array by value to a
procedure?
If we try
to pass an Array by value, it will generate a compile time error.
What will happen if we use ReDim without Preserve?
Using ReDim without Preserve resizes
a dynamic array but destroys its existing contents.
Is it possible to change a static array into a dynamic array?
No. It is
not possible.
What will happen if we try to use ReDim for a static array?
Since
size of static array is fixed, it will generate a compile error, if an attempt
is made to resize the static array using ReDim statement.
Specify difference between SUB procedure and FUNCTION procedure?
- SUB procedure cannot return
a value but FUNCTION procedure return a value.
- SUB procedure cannot be
invoked directly from a worksheet cell , whereas FUNCTION procedure can be
invoked directly from a worksheet cell.
- SUB procedure can change the
contents or format of any cell, whereas FUNCTION procedure cannot change
the contents or format of any cell.
