How much Memory is being used?

[MorkenTheMonk]

Hey gurus,

Inherited a sizeable 16-bit VB3 application that's been resurrected and migrated across to VB6, with further development taking place to introduce new features. All going well (so far).

My question is, are there any tools / techniques available to interrogate how much memory is being used by the application? Specifically, I'd like to know how much memory the numerous Global arrays/variables are using, and whether the memory being used by Global or Local arrays/variables is being freed up when ReDim() or Procedures are exited.

I can use Task Manager to look at my VB6 compiled application Process, and this shows me the amount of Memory (Private Working Set). Currently sitting around 18,000K which doesn't seem too bad at all.

I've also installed Process Monitor from SysInternals, and filtered output to show only my VB6 application, however I'm too much of a novice to be able to interpret the output (!?)

No issues yet with memory on 64-bit Windows 7 / 10 machines, however I'd like the comfort of knowing we're not heading for a limit in the near future.

Thanks for any advice you can give.
