是否创建没有IDispatch支持的COM项目? [英] Creating a COM project without IDispatch support?

问题描述

我正在尝试编写示例COM.
VC ++ IDE提供了创建简单COM对象的向导.
但是，它始终创建具有IDispatch支持的COM对象.

由于某些原因，我需要创建一个实现以下IDL并具有以下要求的简单COM对象:
-必须是COM exe
-一定不能从IDispatch派生而只能是IUnknown
-必须是单身人士

Hi,

I am trying to write a sample COM.
VC++ IDE provides a wizard to create a Simple COM object.
However, it always creates the COM object with IDispatch support.

For some reasons, I need to create a Simple COM object implementing the following IDL with the following requirements:
-- Must be COM exe
-- Must not be derived from IDispatch but IUnknown only
-- Must be a singleton

// typelib filename: Sample.exe
[
  uuid(94EE69BF-4387-4078-B33F-1E9B471D128E),
  version(1.0),
  helpstring("Sample 1.0 Type Library"),
)
]

// library Sample
{
    importlib("stdole2.tlb");
    // Forward declare all types defined in this typelib
    interface ISample;
    [
      uuid(7CEBF979-C4EB-48eb-BE06-FBA1B4929FE7),
      version(1.0)
    ]
    coclass CSample
    {
        [default] interface ISample;
    };
    [
      odl,
      uuid(E3B868FC-7A58-4f28-B895-922D2BE7797F),
      oleautomation
    ]
    interface ISample : IUnknown
    {
        HRESULT _stdcall CreateTester([out, retval] IUnknown** ppTester);
        HRESULT _stdcall Initialize();
        HRESULT _stdcall Uninitialize();
        HRESULT _stdcall get_Name([out, retval] BSTR* Name);
        HRESULT _stdcall GetSettings([out, retval] IUnknown** ppSettings);
        HRESULT _stdcall GetList([out, retval] VARIANT* VarList);
        HRESULT _stdcall SetList([in] VARIANT VarList);
    };
};

我使用VC ++向导创建了一个ATL COM项目，并试图从中剥离IDispatch.
但是，事实证明放弃这项工作太困难了.

有人可以写一个满足上述要求的COM项目吗?

谢谢.

I created an ATL COM project this using VC++ wizard and tried to stripping off IDispatch out of it.
However, it turned out to be too difficult job to give up.

Can someone write a COM project satisfying the above requirements please?

Thank you.
