suresh Understanding the Difference Between ByVal and ByRef in Visual Basic
In Visual Basic, ByVal and ByRef are two different ways to pass arguments to a function or a subroutine.
ByVal:
When a parameter is passed by value (ByVal), a copy of the value is passed to the function or subroutine. Any changes made to the parameter within the function or subroutine will not affect the original value outside of it.
ByRef:
On the other hand, when a parameter is passed by reference (ByRef), the actual memory address of the variable is passed. This means that any changes made to the parameter within the function or subroutine will directly affect the original value outside of it.
It is important to consider the use of ByVal and ByRef based on the specific requirements of the program. Generally, ByVal is used when you want to prevent changes to the original value, while ByRef is used when you want the changes to reflect back to the original value.
Understanding the difference between ByVal and ByRef in Visual Basic and knowing when to use each one can greatly impact the functionality and performance of your program.
