So, I'm basically looking to know how to turn this
BYTE *b
func(b);
into VB6 when b is a dynamic array that has already been redim'ed. Would it be
func(b)
or
func(VarPtr(b))
Thanks, iDomo.

You can do both, really.
But the easy way is func(b), where func is something like func(b() as byte). The b array is then passed by reference.

What if the function's parameter needed to be a pointer to the array of bytes, in Long form?

@iDomo Is the function a native VB function, or is it
Declared?iDomo
It's a native C compiled function. Private Declare Function ReadProcessMemory Lib "kernel32" (hProcess As Integer, lpBaseAddress As Long, lpBuffer As Long, nSize As Long, lpNumberOfBytesRead As Long) As Integer

@iDomo Then you shoud have phrased your question in a completely different way, as both the current question and answer have no relation to what you actually need. The function would be
Private Declare Function ReadProcessMemory Lib "kernel32.dll" (ByVal hProcess As Long, ByVal lpBaseAddress As Long, ByRef lpBuffer As Any, ByVal nSize As Long, ByRef lpNumberOfBytesWritten As Long) As Long, and you would pass b(lbound(b)) for the third param. The function will receive the pointer to the first byte of the array. Do not omit ByVals, they are important.
