For using _beginthread you have to use the multi-threaded runtime lib. In VC6 you can choose the runtime lib in Project Settings->Compiler Settings->Code Generation. Use multi threaded DLL in all your sub projects. And do not mix multiple versions of the runtinme lib. hope this helps Alex

Well pretty obviously you have to turn on multithreading support in your compiler before building the library: check out the code generation options in the IDE. John Maddock http://ourworld.compuserve.com/homepages/john_maddock/index.htm
