DSO Framer - not firing Events in C# - SOLUTION!!!!!

The Microsoft Dso Framer control is a container that can house Office
documents. The control is really great. However I needed to trap the
events that it fired in C#. They worked fine in VB6, not in C# or
VB.NET.
The issue was the way the events were fired. The fix required only
minor changes to the code.
How do I get Microsoft to integrate these changes into the next version
of the framer control?
Thanks,

There are changes to 3 .cpp files

The main change is to utilities.cpp

The code to DsoDispatchInvoke was changed and all calls to it it were
changed:
Change to utilities.cpp
////////////////////////////////////////////////////////////////////////
// DsoDispatchInvoke
//
// Wrapper for IDispatch::Invoke calls to event sinks, or late bound
call
// to embedded object to get ambient property.

STDAPI DsoDispatchInvoke(LPDISPATCH pdisp, LPOLESTR pwszname, DISPID
dspid, WORD wflags, DWORD cargs, VARIANT* rgargs, VARIANT* pvtret)
{
HRESULT hr = S_FALSE;
DISPID dspidPut = DISPID_PROPERTYPUT;
DISPPARAMS dspparm = {NULL, NULL, 0, 0};

CHECK_NULL_RETURN(pdisp, E_POINTER);

dspparm.rgvarg = rgargs;
dspparm.cArgs = cargs;

if ((wflags & DISPATCH_PROPERTYPUT) || (wflags &
DISPATCH_PROPERTYPUTREF))
{
dspparm.rgdispidNamedArgs = &dspidPut;
dspparm.cNamedArgs = 1;
}

SEH_TRY

hr = pdisp->Invoke(dspid, IID_NULL, LOCALE_USER_DEFAULT,
(WORD)(DISPATCH_METHOD | wflags), &dspparm, pvtret, NULL, NULL);
if (!SUCCEEDED(hr)) {

if (pwszname)
hr = pdisp->GetIDsOfNames(IID_NULL, &pwszname, 1,
LOCALE_USER_DEFAULT, &dspid);

if (SUCCEEDED(hr))
hr = pdisp->Invoke(dspid, IID_NULL, LOCALE_USER_DEFAULT,

}

SEH_EXCEPT(hr)

return hr;
}
