This is a repost with an update
Does any one know how to pass a function pointer as a function parameter
from VB .NET to a C dll?
Currently I'm passing it this way
Public Delegate Sub DSCUserInterrup tFunction()
Public Declare Function dscUserInt Lib "dscud.dll" (ByVal board As Short,
ByRef dscuserint As dscUserInt, <MarshalAs(Unma nagedType.Funct ionPtr)> ByRef
functions As DSCUserInterrup tFunction) As Byte
Public Sub count()
dscUserInt(boar d, dscuserint, AddressOf count)
But this isn't working. My program just crashes and exits. Any ideas?
Thanks.

Try the AddressOf()
it might work ;)

Another related question
How do I keep the garbage collector from collecting the AddressOf count or
my funct variable below?
dim func as DSCUserIntFunct ion
func = AddressOf count
Thanks

Dear all,
I thought I understood passing parameters ByVal and ByRef but I
clearly don't! If I define a simple class

Public Name as String
Public Age as Integer
End Class

I was under the assumption that if you pass an object as a param to a method
and inside that method this object is changed, the object will stay changed
when returned from the method because the object is a reference type?
my code is not proving that. I have a web project i created from a web
service that is my object:

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.
