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 is
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 to
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
