“The most important choice in writing is not what you say. It’s what you don’t say.” Eric Gunnerson<\/a> gave me that advice when I was writing my book<\/a>. It’s sort of the writing version of “You don’t know what you do until you know what you don’t do<\/a>.”<\/p>\n

That’s why I’ll write<\/a><\/p>\n

Of course, you probably wonder this magical pfl<\/code> comes from. It comes from the Multilanguage Object in mlang.<\/p>\n

  IMLangFontLink2 *pfl;\r\n  CoCreateInstance(CLSID_CMultiLanguage, NULL,\r\n                   CLSCTX_ALL, IID_IMLangFontLink2, (void**)&pfl);\r\n  ...\r\n  pfl->Release();\r\n<\/pre>\n<\/blockquote>\n
and not<\/p>\n
\n
The pfl<\/code> variable we’ve been using is an interface pointer to the IMLangFontLink2<\/code> interface. We obtain this pointer by calling the CoCreateInstance<\/code> function, asking for the object whose class ID is CLSID_CMultiLanguage<\/code> (defined in the mlang.h<\/code> header file) and specifying the interface ID (IID) of IID_IMLangFontLink2<\/code>. The interface ID is a 128-bit value that uniquely identifies an interface; we use it here to specify that we wish to have access to the IMLangFontLink2<\/code> interface. Since COM uses explicit reference counting, we must remember to call the IUnknown::Release<\/code> method when we are finished with the interface pointer. Each call to the IUnknown::Release<\/code> method decrements the reference count by one, and when the reference count drops to zero, the object is destroyed.<\/p>\n
  IMLangFontLink2 *pfl;\r\n  CoCreateInstance(CLSID_CMultiLanguage, NULL,\r\n                   CLSCTX_ALL, IID_IMLangFontLink2, (void**)&pfl);\r\n  ...\r\n  pfl->Release();\r\n<\/pre>\n

This is why I hate reading technical books. People think it’s better to write fifty words when ten are enough, that you should explain everything in excruciatingly tedious detail just in case there’s a reader out there who sees the word CoCreateInstance<\/code> and says, “Gosh, I don’t know what that is, and I’m going to declare this book useless unless it explains everything from first principles.”<\/p>\n
What next? “The left open brace begins a block of statements”?<\/p>\n","protected":false},"excerpt":{"rendered":"
