Without knowing details of your COM library, I'd look into creating a facade class in .Net and exposing it to COM, if necessary.
Your facade would take a double[,,] and have an indexer that will map from [] to [,,]. |

How should I handle autolinking in wiki page content? |

For basic data retrieval I would be going for Linq without hesitation.

A simple & fair algorithm for shuffling would be to assign a random floating-point number (e.g., between 0 and 1) to each card in the deck, then sort the deck by the assigned numbers.

If you don't actually need any of the features of macros (`__FILE__`, `__LINE__`, token-pasting, etc.) you may want to consider writing a variadic function using `stdargs.h`. Instead of calling `printf()`, a variadic function can call `vprintf()` in order to pass along variable argument lists. |

Doing that is only safe if you are not running on a 64 bit version of windows. The LONG type is 32 bits, but the HANDLE type is probably 64 bits. You'll need to make your code 64 bit clean. In short, you will want to change the LONG to a LONG_PTR.
