Optional Byte Array Parameter
I canNOT get this right. I just want my first parameter to be an optional byte array. The most recent code I've tried is below, and the syntax error I get is "Constant expression is required".
How the heck do I supply a default value for this optional byte array, so that it's an empty byte array by default? (Ubound(a) = 0, or better yet, Ubound(a) < 0)?
Thanks a bunch.
Private Function StartXMLDecompressorThread
Optional ByRef ByteArrayData() As Byte = New Byte() {}, _
Optional ByVal sEXEPath As String = "", _
Optional ByVal sXMLPath As String = "", _
Optional ByVal sOutputPath As String = "" _
) _
As Integer

Did you ever consider altering this to be an overloaded function? Or is it just too many optional arguments to consider (maybe rework it a bit)?

Man, do I feel like an idiot. I keep forgetting that EVERYTHING in .NET is an object, and so can be legitimately set to Nothing.
Thanks for the help.
Thanks for the help.
And have you tried:
Optional ByRef ByteArrayData() As Byte = Nothing
