Host CLR

Hi all,

I'm trying to use a .net api from unmanaged MFC code.
I'm trying to use ClrCreateManage dInstance api, but as shown above,
my
var pDisp equals null before the ClrCreateManage dInstance call.
Can you correct my code ? (Or any other way to do that ?)
#include "mscoree.h"
#pragma comment (lib, "mscoree.li b")
CComPtr<IDispat chpDisp;
HRESULT hr = S_OK;
hr = ClrCreateManage dInstance(L"Sys tem.Windows.For ms.MessageBox,
System.Windows. Forms, Version=2.0.507 27.42, Culture=neutral ,
PublicKeyToken= b77a5c561934e08 9",IID_IDispatc h, (void**)&pDisp) ;
Thansk in advance for your help,
Best,
S.

Let me add some information, if i try with System.Random that is part
of mscorlib
this :
hr =
ClrCreateManage dInstance(L"Sys tem.Random,msco rlib,PublicKeyT oken=b03f5f7f11 d50a3a",
IID_IManagedObj ect, (void**)&pWrap) ;

is working :)
but if i try with my own assembly :
hr = ClrCreateManage dInstance(L"MyA ssembly.Class1, MyAssembly",
IID_IDispatch, (void**)&pDisp) ;

i have the hresult : E_NOINTERFACE value

Nb : my assembly isn't strong signed

Thanks for your answer

What compiler version is your assembly built with? Did you call
CorBindToRuntim eEx? If not, the documentation indicates that the .NET 1.0
runtime gets loaded and you won't be able to load newer assemblies.

Maybe ClrCreateManage dInstance doesn't load the assembly for you. Try
loading System.Reflecti on.Assembly from mscorlib, and call Assembly.Load.
See http://msdn2.microsoft.com/en-us/lib...ft(VS.80).aspx

Have you set the COMVisibleAttri bute on your class?

You can't instantiate S.W.F.MessageBo x, because it has a private constructor
:-)
