Masercam keeps Chook fileHandle open

[Nick Hinde 4D Eng (UK Reseller)]

Hi,

Has anyone noticed that Mr1 keeps the filehandle of the last run chook .dll open? That means if you are working on a Chook you have to quit Mastercam and restart every time you want to overwrite the .dll with the newly compiled version. I tried with the shipped Chooks, running one and leaving Mastercam running and then trying to delete/overwrite the chook I had just run and it was stil "open" even though Mastercam was now doing other stuff. If anyone can suggest what I am undoubtedly missing here I would be most grateful.

Thanks, Nick

You can try the setting the return value from your C-Hook’s m_main function.

 

extern "C" __declspec(dllexport) int m_main (int param)

{

AFX_MANAGE_STATE(AfxGetStaticModuleState());

 

RunApp();

return (MC_NOERROR | MC_UNLOADAPP);

}

 

 

Return values are defined in cgui_ch.h ---

 

code:

---

enum MC_RETURN { 

MC_NOERROR, /// Executed normally

MC_ESCAPE, /// Escape key hit

MC_EXITFUNC, /// Exit current task requested (from outside current task)

MC_ERROR, /// General error code

MC_UNLOADAPP = 0x80000000 }; /// Unload Application on return (you may OR this with other return types)

---

Note that if the C-Hook is referenced in an FT (Function Table) file (which makes it available for mapping to a toolbar and/or keystroke), the MC_UNLOADAPP will have no affect. X loads all the DLLs in the FT files on startup and holds on to them until you shutdown X.

Thanks Roger,

I should have looked in the headers for that one
