// SimpleDataObject.cpp : Implementation of DLL Exports.
// Note: Proxy/Stub Information
// To merge the proxy/stub code into the object DLL, add the file
// dlldatax.c to the project. Make sure precompiled headers
// are turned off for this file, and add _MERGE_PROXYSTUB to the
// defines for the project.
//
// If you are not running WinNT4.0 or Win95 with DCOM, then you
// need to remove the following define from dlldatax.c
// #define _WIN32_WINNT 0x0400
//
// Further, if you are running MIDL without /Oicf switch, you also
// need to remove the following define from dlldatax.c.
// #define USE_STUBLESS_PROXY
//
// Modify the custom build rule for SimpleDataObject.idl by adding the following
// files to the Outputs.
// SimpleDataObject_p.c
// dlldata.c
// To build a separate proxy/stub DLL,
// run nmake -f SimpleDataObjectps.mk in the project directory.

Len has been programming for over 30 years, having first started with a
Sinclair ZX-80. Now he runs his own consulting company,
JetByte Limited and has a technical blog

JetByte provides contract programming and consultancy services. We can provide experience in COM, Corba, C++, Windows NT and UNIX. Our speciality is the design and implementation of systems but we are happy to work with you throughout the entire project life-cycle. We are happy to quote for fixed price work, or, if required, can work for an hourly rate.
We are based in London, England, but, thanks to the Internet, we can work 'virtually' anywhere...
