When i define _MT compile flag the compiling error goes off but i get lot of linker errors.
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
