推荐答案

您正在编写控制台应用程序这一事实应该是无关紧要的.您要实例化一个COM对象并调用一个方法.

您可以用困难的方式做到这一点， [ ^ ]或让IDE帮助您. [ [ ^ ]

The fact that you''re writing a console application should be irrelevent. You want to instantiate a COM object and invoke a method.

You can do it the hard way,[^] or let the IDE help you out.[^]

You don''t say if you''re using managed or unmanaged C++ which will make a big difference, so I can''t really point you to a tutorial, but here''s a start.[^]

如果其中嵌入了类型库，则相当容易

if it''s got a type library embedded in it, it''s fairly easy

// get ATL''s client templates
#include <atlcomcli.h>
// import the typelibrary direct from the dll
#import "<name of your com dll here>" raw_interfaces_only no_namespace

这将在您的输出目录中创建一个.tlh文件-查看对象和接口声明的文件

然后使用该com对象

That will create a .tlh file in your output directory - have a look at that for the object and interface declaration

then to use that com object

// declare com ptr
CComPtr<IwhateverTheInterfaceIs> comInterfacePtr;
// cocreate an instance
comInterfacePtr.CoCreateInstance(__uuidof(theCoClassFromTLHfile))
// then use methods
comInterfacePtr->Method()
