If I BUILD the code below, all works fine. But if I REBUILD the solution
at any time, the following errors are found in the WrapperCOMEXE.i dl:
1) error MIDL2337 : unsatisfied forward declaration :
IQBEventCallBac k
[Coclass 'MyWrapper' ] --> This error occurs within the
MyWrapper Coclass
definition at the line that reads: "[default] interface
IQBEventCallBac k;"
2) warning MIDL2015 : failed to load tlb in importlib: :
sdkevent.dll -->
This warning occurs in the importlib statement that reads:
"importlib("sdk event.dll");".
Here's the WrapperCOMEXE.i dl code:
// EventWrapperCOM EXE.idl : IDL source for EventWrapperCOM EXE

Presumably sdkevent.dll is built for a previous project in your
solution. Ensure you make that project a dependency for this
project, so the DLL (its output) is already built.

I am not a C++ programmer. The sdkevent.dll is already created. How do I
make it a dependency?

How do you forward declare a class that is *not* paramaterized, but is
based on a template class?
Here's what I thought should work, but apparently doesn't:
