invoke    (IMalloc PTR [eax]).Free,@stMalloc,@pidlParent
invoke    (IMalloc PTR [eax]).Release,@stMalloc

书上写的是个COM接口，用来实现选择目录的通用对话框
我不懂COM接口上面的那些看不懂不知道怎么写
我现在想把他用C++实现，上面那些代码要怎么写？
求教，顺便帮解释下COM接口之类的，谢了哈

masm的宏汇编本类就和C语言结构类似

如函数声明
IMalloc_AllocProto typedef proto :DWORD, :DWORD
其实就是
IMalloc_AllocProto(DWORD,DWORD)
结构体也很清楚啊

externdef IID_IUnknown:IID这句
这个东西我换成extern IID IID_IUnknown没用额，别的文件也找不到有这个声明

invoke (IMalloc PTR [eax]).Release,@stMalloc
还有这里的(IMalloc PTR [eax]).Release不清楚什么意思

这里貌似和虚函数表有关，不用去管寄存器的细节，只管调函数就行
