I defined the method GetAllTables through Type Library and if it occurs
exceptions I want to throw them to the client.
In the app server the code like this:
STDMETHODIMP TrdmBCBPubsImpl::GetAllTables(TVariant* vTables)
{
   try
   {
       //...
   }
   catch(...)
   {
      throw;
   }
}
If exceptions occured in the app server it throws.


In the client the code is:
   TCOMItestDCOM Server;
   Server = CotestDCOM::CreateRemote(WideString("server_name"));
   try

   {

      Server->GetAllTables(...);

   }

   catch(EOleException &E)

   {

      ShowMessage(E.Message);

   }

But the exception occured in the app server couldn't be cought.
