After changing my axes incremental step buttons, i broke my Coolant on off buttons. I forgot that i changed the source files a while back when i was working on a different approach of turning coolant on and off.
Now iam trying figure out the coding i had that made the 2 buttons work.But i keep getting 2 errors when rebuilding in VS.

Error    1    error LNK2001: unresolved external symbol "protected: void __thiscall CKMotionCNCDlg::OnCoolant(void)" (?OnCoolant@CKMotionCNCDlg@@IAEXXZ)    KMotionCNCDlg.obj    KMotionCNC

Error    2    fatal error LNK1120: 1 unresolved externals    c:\KMotion432\KMotion\Release\KMotionCNC.exe    KMotionCNC


I still have a KMotionCNC.exe that both Coolant On and Off buttons work. Is there a way to open the source files from this .exe so i can see what i did in the KMotionCNCDlg.cpp file and other files?

Thanks,
Troy
