Hello all:
I write a component using ATL and it includes two interface:ISMath

and

IAMath,
and now I write client codes and want to the file tlb,Look:
#import "Com_01.tlb" no_namespace
#include <windows.h>
#include <iostream.h>

void main()
{
   HRESULT hr;
   hr=CoInitialize(NULL);
    if(FAILED(hr))
{
  cout<<"Initialize COM failed"<<endl;
        return;
}

   ISMathPtr spSFun;
   IAMathPtr spAFun;
   spSFun.CreateInstance(L"Com_01.SMath");
   long s=spSFun->Add(11,12);
   cout<<s<<endl;
   spSFun.QueryInterface(IID_IAMath,spAFun);//It displays this sentence

error
   s=spAFun->Sub(22,11);
   cout<<s<<endl;
   spSFun.Release();
   spAFun.Release();
   CoUninitialize();}

I compile and it displays: 'IID_IAMath' : undeclared identifier,why?how

do?
Thanks very much.

You can also include header file of component serevr

e.g. if the server header file name is Server.h

just copy that file to clients project and include it....instead of
importing tlb file
