We are working on a new library version that contains some UI controls that are used by other applications. Some of these controls have new features that the old applications don't know about. We will disable the new features by default, but there are specific apps for which we'd like to enable them. The apps are likely to exist on th...

I have written a COM component in unmanaged C++ to provide customers access to our database. When using it from an unmanaged language the database connections are correctly cleaned up as the objects go out of scope.
