- SystemEvents.LowMemory<DIV>SystemEvents.LowMemory doesn't seem to work, at least not the way it's documented.</DIV>
<DIV> </DIV>
<DIV dir=ltr style="MARGIN-RIGHT: 0px">I wrote a little app that added a handler for the LowMemory event:</DIV>
<BLOCKQUOTE dir=ltr style="MARGIN-RIGHT: 0px">

<DIV>It got up to 1035mb (which is past when I would have liked the event to fire) and then threw an OutOfMemoryException (without hitting the breakpoint I had in the <FONT size=2>SystemEvents_LowMemory <FONT size=3>handler</FONT>.</FONT></DIV>
<DIV> </DIV>
<DIV>I'd like to experiment with using “free“ memory (memory the system doesn't currently have another use for) as cache in my own apps, but I need to know when the system wants some memory back. Maybe there's another way.</DIV>
