Question

what does putting “()” after a word do? sometimes it doesn’t work

Answer 1

To expand on what Mehrdad said:

The following lines use “()” to declare arrays:

'dynamic array w/o pre-set length'
Dim Doubles() As Double

'array of length 11'
Dim Doubles(10) As Double

'array of Strings initialized with three items'
Dim Strings() As New String() {"String1", "String2", "String3"}

The following line does NOT declare an array:

'here the "()" are treated as a call to the MyObject constructor'
Dim MyObjects As New MyObject()
