creting event handler client in vc++ for Source c# event

[Mayur]

Hello all,

Can any one have the source of How to add event handler in unmanaged MFC
application for
event source which is in Managed(c# class library).

Here is the Event Source code
:
namespace ircConnect

{

public class IrcConnection

{

public delegate void MessageEventHan dler(object sender,MessageE ventArgs e);

public event MessageEventHan dler MessageIncome;

}End Class



Event Client

void CADONET_MFCDlg: :OnFilling() //This is the MFC dialog box event

{

#pragma push_macro("new ")

#undef new

try

{

m_IrcConnection =new IrcConnection() ;

FileWatcherEven ts *f=new FileWatcherEven ts();

m_IrcConnection->add_MessageInc ome=new
IrcConnection:: MessageEventHan dler(m_IrcConne ction,OnMessage Income);

};

im using gcroot template
gcroot<IrcConne ction*m_IrcConn ection;

gcroot<IrcMessa ge*m_IrcMessage ;

void static OnMessageIncome ( Object* sender,
IrcConnection:: MessageEventHan dler* e );

but the compile time error generated as follows

error C3363: 'void CADONET_MFCDlg: :OnMessageIncom e(System::Objec t __gc
*,ircConnect::I rcConnection::M essageEventHand ler __gc *)' : cannot create a
delegate handler for 'ircConnect::Ir cConnection::Me ssageEventHandl er' from a
non-member function or a member of an unmanaged class

THis is not a C# issue, please post C++ questions to the vc NG
<microsoft.publ ic.dotnet.langu ages.vc, that said, the error message tells
it all, your MessageEventHan dler' delegate must be created from a managed
class.
