Convert C++ struct to VB type...

[MerrionComputin]

Hi,

There's this C++ struct that I want to make into a VB type, but it has a syntax that I haven't seen before:

struct {      DWORD BaseMid  :8;

What does :8 mean?

Thanks in advance,
Duncan

It is a bitfield. Means there are 8 bits (seems a bit odd, if someone wanted 8 bits, they should have used a char).

It's a way to skip over to useful bits. Merrion left off part of the statement.

What I find weird is the 'DWORD' part. Maybe it wasn't skipping over. The problem with DWORD is the sign bit. I would have thought ULONG was more appropriate.

Merrion - you can't do bit fields in VB, you have to OR individual groups of bits, messing with RtlMoveMemory.

Could you explain a bit more on this? I think I have used bitfields all of once =).
