Example. The following Visual Basic code illustrates use of the Initialize

method to dimension struct arrays.

Sub foo ()

Dim x As MWStruct

Dim y As MWStruct

On Error Goto Handle_Error

'Create 1X1 struct arrays with no fields for x, and y

Set x = new MWStruct

Set y = new MWStruct

'Initialize x to be 2X2 with fields "red", "green", and "blue"

Call x.Initialize(Array(2,2), Array("red", "green", "blue"))

'Initialize y to be 1X5 with fields "name" and "age"

Call y.Initialize(5, Array("name", "age"))

'Re-dimension x to be 3X3 with the same field names

Call x.Initialize(Array(3,3))

'Add a new field to y

Call y.Initialize(, Array("name", "age", "salary"))

Exit Sub

Handle_Error:

MsgBox(Err.Description)

End Sub

Property Item([i0], [i1], …, [i31]) As MWField

The Item property is the default property of the MWStruct class. This property

is used to set/get the value of a field at a particular index in the structure array.
