IB Ax from C# to C++/CLI

I would like to know if someone use the IB AX with the C++/CLI language,
I don't know what to declare in C++/CLI, in order to get the same think as C#.(in C# it generates the event method automaticcaly with multi tab button)

C++/CLI code:

void cIB::Init_AxTWS(AxTWSLib::AxTws^ temp)
{
axTws1 = temp;

axTws1->errMsg += gcnew ::_DTwsEvents_errMsgEventHandler();

}


C# code:

public bool Init_AxTWS(AxTWSLib.AxTws temp)
{
// Set the ActiveX
axTws1 = temp;
axTws1.errMsg += new _DTwsEvents_errMsgEventHandler(axTws1_errMsg);

}
void axTws1_errMsg(object sender, _DTwsEvents_errMsgEvent e)
{

}
