No errors, just don't know how can I make the sink object 'see' the main form or its controls.

Here's the sink that is created in:


public __gc class Form1 : public System::Windows::Forms::Form -style form.

Connecting to COM and reveiving an event is no problem, but how do I pass the parameter received in 'OnEvent' into a control on the form?


#ifndef __SINKBASE
#define __SINKBASE

#include <atlbase.h>
#include <atlhost.h>

#import "xxx.dll" named_guids raw_interfaces_only
#include "xxx.h"

template <UINT nID, class T, const IID* pdiid>
class SinkBase : public IDispEventSimpleImpl<nID, T, pdiid>
{
public:
SinkBase()
{
}

// fill in the _ATL_FUNC_INFO structured depending on DISPID
virtual HRESULT GetFuncInfoFromId(const IID& iid, DISPID dispidMember, LCID lcid, _ATL_FUNC_INFO& info)=0;
};

class MySink : public SinkBase<0, MySink, &DIID__IxxxEvents>
{
public:
MySink()
{

}

BEGIN_SINK_MAP(MySink)
SINK_ENTRY_EX(0, DIID__IxxxEvents, 1, OnEvent)
END_SINK_MAP()

HRESULT GetFuncInfoFromId(const IID& iid, DISPID dispidMember, LCID lcid, _ATL_FUNC_INFO& info)
{
if (InlineIsEqualGUID(iid, DIID__IxxxEvents))
{
info.cc = CC_STDCALL;

switch(dispidMember)
{
case 1:
info.vtReturn = VT_I4;
info.nParams = 1;
info.pVarTypes[0] = VT_BSTR;
return S_OK;

default:
return E_FAIL;

}
}
return E_FAIL;
}

HRESULT __stdcall OnEvent(BSTR eventString)
{
return S_OK;
}
};
