*resolved* What's wrong with memory usage!!?

[MrPolite]

I have a simple program with only a list view in it...yesterday when I was running it, it was only using 3 MB of ram, but now when I run it, it uses 14MB of ram (I do garbage collection very often, so it's not because of that)

why is this like this?!!!

How do you do Garbage Collection? All you can do is schedule something for Garbage Collection from what I understand. When the VM decides that resources are getting low, it then will reclaim resources. So it doesn't really matter how much ram your using, if you need more, and there is stuff that still hasn't been removed from memory, then the collection process will free the needed resources. It is kind of weird, but it works.

I've noticed similar things with a variety of apps with a variety of controls, not just ListView. Seems like Windows FOrms just eats a lot of memory, although it's all tempory memory (minimize your app and watch memory usage go down to zeroish). I haven't worked with any projects big enough to bother me yet, partly because my work is so simply and partly because I have 512MB. Not sure how .NET apps would behave on a system that is tight for memory.

well I was forcing one:
GC.Collect()
GC.WaitForPendingFinalizers()


I removed this and I tested my app... I left the app open for like an hour and it works fine....the ram goes high, but it frees the memory oftern. Works fine I guess
