This project shoul be able to run "out of the box" ================================================== by pointing to file ...\MakeProbe\MakeProbe.dsw in Microsoft VS6 VC++. File MakeProbe_C.c is all that needed to recreate project in for another compiler. How this project was created: ============================= in VS6 VC++ created new workspace: name MakeProbe right click and added new project chosen Win32 console application name MakeProbeF what kind of project? answered: empty application in file view: added new file MakeProbe_C.c which was previously created as ...\MakeProbe\MakeProbeF\MakeProbe_C.c went to menu\Build\Set Active configuarations and set Release saved the job backed up top folder Clicked on menu\Build\Buid All Removed Release\Make_Probe_C.obj MakeProbeF.pch vc60.idb Folder Debug Made file: MakeProbeF.bat with contents: MakeProbeF.exe pause Ran test on Windows 98.
