Processes memory usage problem

[zcecil]

I wrote a program which checks process lists regularly.
Timer1->Interval = 10 ms.

Code: Select all

DelphiInterface<IProcesses> processes = Processes("*");
void __fastcall TForm1::Timer1Timer(TObject *Sender)
{
    proc->RefreshItems();

    for( int i=0; i<proc->ItemCount; ++i){
        if( proc->Items[i]->IsValid() ) {
                // do nothing, just for test
        }
    }

}

The program's memory usage is growing when processes created or closed, and it doesn't seems to decrease.

Try minimizing the program and restoring it again. Does the memory consumption go back again then?

[zcecil]

The memory usage drops from 76xxK to 1xxxK when minimized, then it keeps growing slowly( same speed as not minimized).

After I restore and minimized again, it drops back to 1xxxK and then growing again.

What's the cause of this problem?

That's the typical behaviour of Delphi's/Windows' memory manager. It's no memory leak, it's just the way it is. Nothing to worry about, I think.
