Hour 21

   

1:

If you use a .NET object within a COM-based application, do you need to release any interface pointers you obtain or does the common language runtime still perform garbage collection?

A1:

Because your COM object is not running within the confines of the common language runtime, you must release your interface pointers.

2:

What happens when a parameter to a method within a .NET object is a custom data type that you created and you wish to build a type library using the assembly that contains this custom data type?

A2:

You will have to implement a custom marshaler.

3:

If TlbImp.exe creates an assembly, then what does the tool TlbExp.exe do and how is it different from the RegAsm.exe tool used during this hour?

A3:

TlbExp.exe creates a type library from an assembly. RegAsm.exe does the same, but it also registers that type library, whereas TlbExp.exe does not.
