Greetings.  What I need to do is pass the underlying ADO _Connection * from a TADOConnection to a Microsoft DLL so that I can use the connection from the borland app in an MS DLL.  

Here are some things that I have tried:

In the borland app.
--------------------------
assume that dllcall is some function in the dll that takes one param (an ADO _Connection *)

TADOConnection *someConnection = new TADOConnection(NULL);

(dllcall)((_Connection *)someConnection->ConnectionObject);
--------------------------


in the MS dll
--------------------------
__declspec(dllexport)
void dllcall(_Connection * conn)
{
    _ConnectionPtr c = conn;
    c->Execute(... /*assume valid params*/)
}
---------------------------

everything works fine until the call to ->Execute.  I then get an access violation at address 5.  Any ideas on what I'm doing wrong or other ways to do this?  thanks!
