Many users run the macro.... if I want to make some changes - the macro is locked? Can I add some commands to release the macro after the user run it?
Solidworks do not give me a warning "not saved" when save the changes in the macro editor.
This is if I want to rename a macro file - to replace with a new:
What I use to do was to write a macro that used the RunMacro2 method with option swRunMacroUnloadAfterRun to call the macro I really wanted to run (I think this is what Artem was referring too). This "locks" the first macro but frees up the second for editing after it has completed being run. Be aware if someone else edits the second macro then you will be locked out until they close their SW session.
Another possibility is to load code at runtime.
GitHub - erppdm/VBADC: A tool to load VBA code dynamically at runtime.
If you run the macro from the API, there is a flag to explicitly unload the macro after run, but I am not sure if the one exists if you run the macro manually (there is the one for VSTA, but I do not think it applies to the VBA macros).
Alternatively, you can use Toolbar+ utility as there is an option to unload macros after run
