Help with Unmanaged Class

[Rick]

We have an class sent to us by a vendor in a .h file. This class controls
access to a subsystem for gathering data. Currently we are using C++ 6.0 to
access this class. Now we want to move to .net. The class sent to us can not
be compiled as managed code so I have built a managed wrapper class... here
is the general code

#using <mscorlib.dll >

#pragma once

using namespace System;

#pragma unmanaged

#include "VendorData .h"

#pragma managed

namespace rvimrh

{

public __gc class rvimrh

{

private:

VendorData __nogc* objimrh;

public:

rvimrh() : objimrh(new VendorData)

{

}

~rvimrh(void)

{

if(NULL != objimrh)

{

delete objimrh;

objimrh = NULL;

}

}

My question is - We want to call this from a VB.net program - is there
anyway to call the functions in the unmanaged class without setting up
"driver" calls from the managed class for example one of the functions in
the unmanaged class is

void ServerIP ()

{

char * ip;

}

if I setup a function in the managed class as

void ServerIP ()

{

char * ip;

ip = objimrh->ServerIP();

}

I can call this function from the VB program and it then calls the function
in the unmanaged class but there are about 75 functions in the unmanaged
class and I would hate to have to code everyone of them if I don't have
to... Obviously we can't change the vendor code as they send us the new
class whenever changes are made

Any help or references to documentation pertaining to this would be most
appreciated

Thanks
