interface写法 ( 积分: 50 )

delphi中:
type
IPorte = interface
['{24F71F58-B71A-4430-86E6-6A4A183D7579}']
function Start(Device:byte) : boolean ;
procedure Shutdown();
function OpenDoor(Addr:byte) : boolean ;
function CloseDoor(Addr:byte) : boolean ;
function GetStatus(Addr:byte;var Status:word) : boolean ;
function GetCount(Addr:byte;
var Count:word) : boolean ;
function Reset(Addr:byte) : boolean ;
end;
翻译成c++:
typedef
__interface INTERFACE_UUID
["{3F969F98-1CC6-443F-9E1D-62AD08933925}"]
IPorte : public IInterface
{
virtual BOOL Start(unsigned char Device);
virtual void Shutdown();
virtual BOOL OpenDoor(unsigned char Addr);
virtual BOOL CloseDoor(unsigned char Addr);
virtual BOOL GetStatusGetStatus(unsigned char Addr,unsigned int *Status);
virtual BOOL GetCount(unsigned char Addr,unsigned int *Count);
virtual BOOL Reset(unsigned char Addr);
}
不对,该怎么写?

解决了,用BCB的COM向导.
新问题啊:我是写在DLL中的,如何输出接口啊:
extern "C"
XPORT_TYPE __stdcall IPorteCtl *CreatePorte;
不认啊

IPorte = interface
['{24F71F58-B71A-4430-86E6-6A4A183D7579}']
function GetStatus(Addr:byte;var Status:word) : boolean ;
function GetCount(Addr:byte;
var Count:word) : boolean ;
function Reset(Addr:byte) : boolean ;
end;

TPorte = class(TObject, IPorte)
function GetStatus(Addr:byte;var Status:word) : boolean ;
function GetCount(Addr:byte;
var Count:word) : boolean ;
function Reset(Addr:byte) : boolean ;
end;
翻译成c++:
__interface INTERFACE_UUID("{1DCCA889-3748-4FDA-8D4D-142BACC3BCF2}&quot
IPorte : public IInterface
{
public:
virtual bool __stdcall GetStatus(unsigned char Addr, unsigned int *Status);
virtual bool __stdcall GetCount(unsigned char Addr, unsigned int *Count);
virtual bool __stdcall Reset(unsigned char Addr);
};
class CPorte : public IPorte //这里不对的,多继承怎么写?public TObject, public IPorte 不对
{
CPorte();
~CPorte();
bool __stdcall GetStatus(unsigned char Addr, unsigned int *Status);
bool __stdcall GetCount(unsigned char Addr, unsigned int *Count);
bool __stdcall Reset(unsigned char Addr);
}
通过;以下未通过,请帮忙看看:
CPorte::CPorte()
{ //在这里提示共四个错: can't create instance of abstract class CPorte.
//class 'CPorte' is abstract because of '__stdcall IUnkown::Addref() = 0'
//type 'CPorte' may not be defined here
//constructor cannot have a return type specification
}
CPorte::~CPorte()
{
}

这句也没会写:
function CreatePorte : IPorte;
export;
stdcall;
翻译成c++:
#define XPORT_TYPE __declspec(dllexport)
extern "C"
XPORT_TYPE __stdcall IPorte *CreatePorte();//不正确,请教

终于完全解决:
头文件:
#include <system.hpp>
typedef
__interface INTERFACE_UUID(&quot;{1DCCA889-3748-4FDA-8D4D-142BACC3BCF2}&quot

virtual bool Status(unsigned char Addr, unsigned int *Status) = 0;
virtual bool Get(unsigned char Addr, unsigned int *Count) = 0;
virtual bool Reset(unsigned char Addr) = 0;
} IPorte;
extern &quot;C&quot;
XPORT_TYPE IPorte *CreatePorte();

那我接分！ []
你这种学习方法值得学习和赞扬，不依赖别人！
