Attempting to pass a VBScript Array of Bytes to a C# Managed COM object has
resulted in some very undesirable and strange behavior. When definining a
method in my C# COM class as "void Write(byte bBytes)" or "void
Write(byte bBytes, int nLen)" or "int Write(byte bBytes, int
nLen)"VBScript returns a "Invalid procedure call or argument" exception.
However when I define the method as "int Write(byte bBytes)" it works just
fine. Unfortunately...

I’ve got a C# library that I’ve built into a COM component that will be used
from a VC++ 6 application and while the creation of the COM object side of
things seem to be working fine, using the object fully is another matter.
On the C# side of things I’ve got an object defined like so:
public class PID : IPID
{
private string type;

Hi all,
I need to implement an unmanaged function that gets a SafeArray and
hands it over to a managed function having the managed array-type.
Using MarshalAs I can call unmanaged functions having SafeArray from
managed code. But here I need this vice-versa...
I assume it is doable with MarshalAs magic, but how?
Thanks
Christian

I'm using VC6.
i have a DLL written in VC6 and used by VB6( and VBA Excel),
i use SafeArray as parameter, the array is created(declared), in VB
and C++ fill it.
now i need VC++ to get an array of array of different sizes, and VB
can't know the size of these arrays, so the arrays will be 'created'
in VC.
here the code that i use(and it crashes):

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
