Expand|Select|Wrap|Line Numbers
  1. Public Sub MyFunction(ByVal Filename as String, Optional FileData as Byte())
  2.  
The optional keyword requires me to set a default value - which is understandable, but I cannot figure out the syntax to do that here...

Expand|Select|Wrap|Line Numbers
  1. Public Sub MyFunction(ByVal Filename as String, Optional FileData as Byte(){0})
  2.

1. Best practice is to use an overloaded function/sub rather than an optional parameter anyway.

2. If you must, then set the default to Nothing

  1. Public Sub MyFunction(ByVal Filename as String, Optional FileData as Byte()=Nothing)
  2.
