Passing parameters - VBA

-

Hello Readers,

Welcome to Coding by Learning !!! 😀 

Most of the programming languages has the concept of passing parameters to functions in different ways. Python, C, C++ and Java programming languages have the concept in the name of Call by value and Call by reference.

In VBA , It is arrived using keywords ByVal and ByRef.


Difference between ByVal and ByRef




















Now lets see the concepts with an example

Here in the example, I have written a sub procedure for calculating sum of 2 numbers. I have created 2 functions "add2Numbers_byval" and "add2Numbers_byref" for differentiating the concepts.








Output as follows :-














Look at the output. The value of iNum2 is same using ByVal and It is modified using By Ref.

Happy learning & Happy Coding !!!
