• Visual C++ Writing Scalable IOCP Socket Apps

  Ok, so I have done a fair amount of research, and I dont "get it". I understand IOCP is a huge and powerful concept, and relatively new. Anyway, I am having a LOT of problems while setting it up, and not sure if what I'm doing is what its supposed to be doing. Before you direct me to a link just yet, I'll show you were I have looked: http://msdn.microsoft.com/msdnmag/issues/1000/winsock/ http://win32.mvps.org/network/sockhim.html And an ungodly amount of time in the MSDN winsock functions/structs/etc. The problem with the first 2, is they give a good dive into it, but the example source code doesnt really show the steps of doing it. The 1st link doesnt go a ...Show All

• Visual C++ Change/Bug in CHtmlStream::Write() in MFC8/VC8???

  I have an MFC ISAPI DLL that calls CHtmlStream::Write() to write some binary data back to the client. For example: BEGIN_PARSE_MAP(CMyISAPIExtension, CHttpServer) ON_PARSE_COMMAND(Default, CMyISAPIExtension, ITS_RAW) DEFAULT_PARSE_COMMAND(Default, CMyISAPIExtension) END_PARSE_MAP(CMyISAPIExtension) void CMyISAPIExtension::Default(CHttpServerContext* pCtxt, void* pVoid, DWORD dwBytes) { pCtx->m_pStream->Write(buf, len); } In MFC 7.1, the client receives a buffer that is len in size but in MFC 8, the client receives a buffer that is len+2 in size. The first two bytes are '\r' and '\n'. Does anyone know what is causing this I can compile the same simple solution in both compiler versions and simply changing ...Show All

• Visual Studio 2008 (Pre-release) WCF using PNRP over VPN

  I tried creating a sample WCF (using .Net 3.0 RC1) app using PNRP and it works over the intranet, but not over VPN. The network admin thinks this happens because PNRP by default tries to use IPv6. Anybody knows how to configure it using IPv4 could there be another explanation for the problem Hi Javier, Your admin is correct that PNRP does not work over IPv4. It uses IPv6. However, the beauty of IPv6 is that: * On the Internet, you only need to enable it on the end machines and not all over the Internet. IPv6 has a mechanism by which it will tunnel through an IPv4 network. On Vista, IPv6 is enabled by default and you don't have to do anything. On XP, installation of the optional p2p component automatically installs IPv6 as well. ...Show All
