error 496 - Destination File Write Error

[lac la]

I am trying to convert QBasic to PBCC2.0 and PBDLL6.0 for a large
application. I need to how to unload the library so I can modify
and compile it while the application is running and load it everytime
it is needed.
I have tried to use FREELIBRARY to unload the DLL successfully but
the DLL is still Write-protected.

I use freelibrary/compile DLL/reload with the exe which calls the library still running all the time without any problems.

Note that if you have a DECLARE in the EXE which specifies the LIB, and the procedure is referenced in the EXE, option,that DLL does not not unload and the file remains write protected. (As far as I can figger it out).

If it makes a difference, I do not launch the "using" EXE from the IDE, I launch from Explorer.

To be more specific, if you need to be able to unload the library, you need
to load the library dynamically (using LoadLibrary). In that case, the calls
to the library routines must be done using CALL DWORD syntax rather than
through the implicit handling used with the DECLARE xxx LIB "zzz" approach.
If you search the Forums here for "LoadLibrary", you will find examples of
how this may be accomplished.
