UsingMFC.h File Reference
If you're building with the JetByte Tools libraries and mixing the code with MFC then you may have problems. See here
for more details on the likely problems. Including this file is likely to fix those problems as it fixes up the library link order. You only have to include this file once, usually in the 'main()' .cpp file. NOTE THAT YOU MUST INCLUDE THIS FILE BEFORE Admin.h.
