Current situation:
a) Start an application
b) during multiple file processing the available "Physical Memory" decreases to a level of about 120000K
c) as a result that application collapses with an "out of Memory"-error
d) freeing memory with something like this ...
FreeMem.vbswon't make it directly as the application rejects to go on processing without being reinitialised/restartet.

For that reason I wanna monitor the process via AHK's DllCall() function, using kernel32.dll's GlobalMemoryStatus function. Unfortunatley that function delivers its outcome to a structure (MEMORYSTATUS), which looks to me that I can't access/parse it to my needs. Any idea?

ich hab die Frage auch im Deutschen Forum gepostet. Irgendwelche D(ll)-Patrioten hier inkognito unterwegs ??

Wouldn't a simple "SetTimer - Reload" be sufficient?

I might have lost you but the reload is used to reload an AHK script (AFAIKTFM). If that would work regarding the system, I additionaly would have to face a following login procedure for the collapsed/terminated app. Therefore I would prefer to refresh the system before the target app will be impacted by a memory issue.

Thx for you contribution.

I assumed by "application" you meant ahk script. If that is the case, then a reload would presumably restore the memory. (unless ahk has a memory leak). Otherwise, I can't be of any help.

This gives you the percentage of the used memory vs. the total physical memeory

Check antonyb's implementation.

Thx gents.
While I've investigated the meaning of some pseudo cryptic aka "Ich versteh hier nur Bahnhof" parts of the given code, I felt ashamed a little . Right at the DllCall help page there's a paragraph: Structures and Arrays .
OMG, BoBo RTFM Nevertheless, it has needed samples like yours, to clearify in detail different aspects which would have been difficult to identify without them.
Thanks again. Much appreciated
