Passing C++ Class pointers via C# to another C++ Class

[AHSommer]

Hi.

I have a C# application that is in need of fetching a C++ class pointer held within a COM object and pass that through to another COM object to populate an equivilent C++ class pointer.

ie:
COM class One creates a class Apple.
COM class Two needs to use COM Class one's instance of Apple.

However, C# application is only link between them.

I have created the ref/out methods on the COM object to pass out the Apple class pointer. Conversely, the other COM object has a method to accept by reference an object.

The trick is what object??

this is the class that sends and needs the pointer
STDMETHODIMP CLogger::get_logClassPtr(LONG ** pVal)
{
*pVal = (LONG*)&pLog;
return S_OK;
}

STDMETHODIMP CLogger::putref_logClassPtr(LONG * newVal)
{
fCreatedInternally = false;
pLog = (CCQLog *)newVal;
return S_OK;
}

this is the link between them
ILogger pLog;
pLog = new CLoggerClass();
ICLIWrapper pDB;
pDB = new CCLIWrapperClass();
pDB.setLogClass = pLog.get_logClassPtr();

(I'm a c++ person, not a c# person ;) )
