Strcmp requires that both strings be terminated with a null character When the allowedTags array is defined each element has a null character appended automatically, but the tag value had a null character appended manually before being passed to the findTag function If a match is found the function returns the ID of the tag, which is simply the number of the row in the allowedTags array in which the match was discovered with 1 added to it The reason for this is that array elements are numbered from 0 but we want the first entry to be called 1, the second to be 2, and so on, and for the value 0 to represent no match found.

To expose a managed class to COM like this, the class must have a public default constructor. This is a constructor without any parameters. Unless you explicitly add a default constructor and make it private, or add your own parameterized constructor, you get one for free without actually specifying one in code. Without this constructor, you are unable to activate an instance of the class via COM. Of course, you can add other parameterized constructors to the class, but these are visible only to managed code and are not exposed to COM clients. The class must also be public and cannot be abstract. In other words, you must be able to create an instance of the class. As long as you are able to live with the limitations of the generated class interface, this is a workable approach to COM interop. By setting a couple of project options, you are able to quickly expose your managed class to COM clients. The limitations include the following: This approach is safe only when using late binding as demonstrated here. It is possible to generate a class interface that supports early binding, but that exposes you to a number of potential problems. Using early binding with a class interface is discussed in detail in the next recipe.
