ByVal is a VB keyword that specifies a variable to be passed as a parameter BY VALUE. In other words, if the function or sub changes the value of the internal variable, it does not change the value of the external variable that was passed to it.

ByRef is a VB keyword that specifies a variable to be passed as a parameter BY REFERENCE. In other words, the pointer to the variable is passed and any change to its value made within the function or sub will change its value outside the function/sub.
