预定义的IDL FILE中没有类型定义 [英] No type definitions in pre-defined IDL FILE

问题描述

首先，

使用普通 C ++，而没有ATL，MFC尝试使用COM Object接口.

Using plain C++, without ATL, MFC attempting to use COM Object interface.

使用 oleview (OLE/COM对象查看器)-用于设计IDL代码.

Using oleview (OLE/COM Object viewer) - used to engineer the IDL code.

在此阶段，使用 MIDL 编译器，现在我在尝试生成以下内容时遇到麻烦:

At this stage, using MIDL Compiler, now I'm having trouble trying to produce the following:

cmd行上的语法:

midl/nologo/env win32/tlb.\ S8_.tlb"/h.\ S8_.h"/iid.\ S8_i.c" S8.idl

midl /nologo /env win32 /tlb ".\S8_.tlb" /h ".\S8_.h" /iid ".\S8_i.c" S8.idl

• 对应的.TLB(类型库)
• .H(标题)
• IID定义包括文件(* _i.c)
• 代理(* _p.c)

• A corresponding .TLB (Type Library)
• A .H (header)
• An IID definitions include file (*_i.c)
• A proxy (*_p.c)

MIDL编译器错误:

MIDL compiler error:

S8.IDL(513):错误MIDL2025:语法错误:期望在"S8SimObject"附近输入类型规范

S8.IDL(513) : error MIDL2025 : syntax error : expecting a type specification near "S8SimObject"

    HRESULT LinkSimObjects(
                    [in] S8SimObject* SourceObject, ####line 513 ####
                    [in] S8SimObject* DestObject,
                    [in] float TravelTime);

推荐答案

MIDL编译器错误

S8.IDL(513):错误MIDL2025 :语法错误:在"S8SimObject"

MIDL compiler error

S8.IDL(513) : error MIDL2025 : syntax error : expecting a type specification near "S8SimObject"

在IDL文件的顶部添加前向声明-

Add a forward declaration - at the TOP of IDL file:

• 导入"ocidl.idl"；
• 接口S8SimObject;
