C++ ATL Server project

[devvvy]

I was working on a C++ ATL server project and been using m_HttpResponse object like "cin" object to stream response back to client. However, I can't find where this m_HttpResponse object comes from, I searched the entire handler class declaration. m_HttpResponse is nowhere to be found. And what's more interesting is that the handler class doesn't derive from anything!?? And there's no #include or#using statements at the top of the header file: #pragma once [ request_handler("Default") ] class CMyHandlerClass //Derive from nothing - no inheritance observed! { //m_HttpResponse declaration?? }; The code works fine, just not sure why/how it worked. norm

Erm, aren't all request handlers done as CRequestHandlerT< yourclass [, CComSingleThreadModel [,CHtmlTagReplacer< yourclass >]] > anyway? That means they that yourclass doesn't need to derive from it... Steve S [This signature space available for rent]

Note this line: norm wrote: [ request_handler("Default") ] From MSDN: "The request_handler attribute will usually add CRequestHandlerT as a base class. If the soap_handler attribute has been applied to this class, CSoapHandler will be added as a base class instead. If the class to which this attribute is applied already derives from IRequestHandler, then no base classes will be added." To be honest, I don't like these attributes - they hide too much IMHO.

Thanks. norm

:confused: I understand what you've said here, however I cannot find why I constantly receive the error: error C3358: 'CSoapHandler': symbol not found I have the code exactly like the sample OnlineAddressBook from the MSDN library yet I get the error whereas that app does not. Such simple things can stop a programmer for hours. Here is the code I am using. Note that the Web Service this code is in compiles fine, it's when I compile the SRF (ATL Server) project that the error occurs, let me know if you need to see more code. // DataConsumerWS.h : Defines the ATL Server request handler class // #pragma once namespace DataConsumerWSService { const wchar_t MYDATASOURCE[] = L"Provider=SQLOLEDB.1;Persist Security Info=False;User ID=me;Initial Catalog=mine;Data Source=SERVER;Use Procedure for Prepare=1;Auto Translate=True;Packet Size=4096;Use Encryption for Data=False;Tag with column collation when possible=False"; // all struct, enum, and typedefs for your webservice should go inside the namespace // IDataConsumerWSService - web service interface declaration // [ uuid("2E179D71-E436-42EE-A1D6-00758BF3D7AA"), object ] __interface IDataConsumerWSService { // HelloWorld is a sample ATL Server web service method.
