DCOM简单示例(01)

本篇文章介绍了如何写一个简单的DCOM服务端(EXE模式)。

1、VC新建工程,ATL->ATL Project(名称为ATLExe)->类型选择Executable(EXE)->Finish

2、工程视图,ATLExe工程,右键->Add->Class->ATL->ATL Simple Object->类名为JustATestExe,ProgID为ATLExe.JustATestExe

3、切换到类视图,ATLExe项目下的IJustATestExe接口上右键Add Method
名称:Add
参数1:[in]LONG a
参数2:[in]LONG b
参数3:[out,retval]LONG* c

4、类视图,ATLExe项目下的IJustATestExe接口上右键Add Method
名称:SayHiTo
参数1:[in]BSTR someOne
参数2:[out,retval]BSTR* retValue

5、打开JustATestExe.cpp完成两个函数

STDMETHODIMP CJustATestExe::Add(LONG a, LONG b, LONG* c)
{
	// TODO: Add your implementation code here
	*c = a+b;

	return S_OK;
}


STDMETHODIMP CJustATestExe::SayHiTo(BSTR someOne, BSTR* retValue)
{
	// TODO: Add your implementation code here
	CComBSTR sResult("Hi ");
	CComBSTR sName(someOne);
	CComBSTR sMark("!");
	sResult.AppendBSTR(sName);
	sResult.AppendBSTR(sMark);
	*retValue = sResult.Copy();

	return S_OK;
}

6、编译

7、注册

ATLExe.exe /regserver

8、反注册

ATLExe.exe /unregserver
