COM/DOCM中的IDL文件问题
目前我要写一个客户端,与以有的DCOM服务器通信,接口函数是行业协会制定的,协会提供了接口标准,并提供了一个IDL文件和C++的头文件,格式如下:例子[
uuid(D94112AF-05A3-4294-AD76-7EA97F512592),
version(1.0),
helpstring("EasyDCOM Library")
]
library EasyDCOM
{
importlib("stdole2.tlb");
importlib("STDVCL40.DLL");
[
uuid(B5D53700-D644-43A6-832B-4FAF482CA277),
version(1.8),
helpstring("Dispatch inte易做图ce for HostInfo Object"),
dual,
oleautomation
]
inte易做图ce IHostInfo: IDispatch
{
[
propget,
id(0x00000001)
]
HRESULT _stdcall Info([out, retval] BSTR * Value );
};
[
uuid(342B12F3-EB07-4579-B026-B140DB1E468D),
version(1.0),
helpstring("HostInfo Object")
]
coclass HostInfo
{
[default] inte易做图ce IHostInfo;
};
};
怎么接上去?一般调入DCOM,需要.cpp和.h文件,但DCOM服务器厂家说与他们无关系,只要采用行业协会的通信标准就行了,也就是说他们不提供.cpp和.h文件,我考虑是不是通过IDL文件来调用,网上资料idl可通过midl.exe生成.h,.c等文件,生成tlb文件,再生成dll,我通过midl生成了tlb和dll文件,但没有生成.h,.c等文件,不知如何使用了,协会提供的C++头文件有点像写服务器时用的,现在我的问题是:能不能通过idl文件来调入,写程序,如果可以,怎么用,我用midl ***.idl时,直接生成了tlb文件,没有生成.h,c等文件,是不是idl文件格式不同,怎么修改?
我在CB版也发了贴,不知有没有违反规则 --------------------编程问答-------------------- 我用你的IDL代码放到工程中编译,出来.h和.c文件了
.h文件为:
