suresh The Difference Between ByVal and ByRef Parameters in Visual Basic
When working with Visual Basic, it is essential to understand the difference between ByVal and ByRef parameters. The focus keyword for this topic is "ByVal and ByRef parameters in Visual Basic."
ByVal: When a parameter is passed by value (ByVal), a copy of the original data is passed to the function or subroutine. Any modifications made to the parameter within the function do not affect the original data outside of the function.
ByRef: In contrast, when a parameter is passed by reference (ByRef), the memory address of the original data is passed to the function or subroutine. This means that any changes made to the parameter within the function will directly affect the original data outside of the function. ByRef parameters allow for two-way communication between the calling code and the function.
It is important to choose the appropriate parameter passing method based on the requirements of your program. By understanding the distinction between ByVal and ByRef parameters in Visual Basic, you can ensure that your code behaves as intended and avoid unexpected results.
