[id(1), helpstring("method SearchCust")] HRESULT SearchCust([in] BSTR bstrcustid,[out,retval] _Recordset **ptr);

由于用到_Recordset类型，所以必须

    importlib("C:\Program Files\Common Files\System\ADO\MSADO15.DLL");

于是整个idl文件应该改写为以下方式：

// FindCust.idl : IDL source for FindCust.dll

//

// This file will be processed by the MIDL tool to

// produce the type library (FindCust.tlb) and marshalling code.

import "oaidl.idl";

import "ocidl.idl";
