array. When dllgetclassobject requests a factory class object, it searches for this array to see if there is a factory class object that matches clsid. When it finds a matched CLSID, it creates a class factory object and returns the class factory pointer to cogetclassobject. Then the client can call iclassfactory based on the class factory pointer returned :: the createinstance method creates a component, and the class factory creates a COM component based on the methods defined in the array.

, cparticle is not very complicated. It has a series of public variables, the attributes of the particles-set the default value through the constructor, And the inline function executes the update. Don't worry about updating functions-you will know how it works later. Now let's look at cparticle's mother cparticleemitter. Cparticleemitter This class contains our particle array, using particle attributes (gravity, texture, etc) Class cparticleemitter {Public: cparticleemitter (); Virtual ~ Cparti

Link to xmllite. lib and include the xmllite. h header file in the Windows SDK to access them. The generated com style interface uses the familiar iunknown interface method to manage the lifetime. The com istream interface also plays a role and indicates memory. In addition, there is no com dependency; no
