Event Driven Programming

• ReDim is using for declaring or resizing the array size.
• The control array to be added must be an element of the existing array created at design
time with an index value of O.

7.5 Keywords

Dynamic array: The size of the array can be changed at the run time size changes during the
program execution.
Fixed-size array: The size of array always remains the same-size doesn’t change during the
program execution.
LBound and UBound functions: The LBound and UBound functions to retrieve the lower and
upper indices. If the array has two or more dimensions.
Multidimensional arrays: Multidimensional arrays is to represent tables of values consisting of
information arranged in rows and columns.

UDT structures: UDT structures can include both static and dynamic arrays.
