Slaying the 'virtual' memory monster [ Edited ]

[hjgode]

I always see, that many windows mobile programmers are not aware of memory limitations on limitted resources on windows ce 4.2 and 5 based devices.

Although Darren published a doc with many links but no information, here is a link to a very good (and old) article about memory in windows ce devices: http://blogs.msdn.com/b/hegenderfer/archive/2007/10/01/slaying-the-virtual-memory-monster-part-ii.as...

Do not miss the first article on that http://blogs.msdn.com/b/hegenderfer/archive/2007/08/31/slaying-the-virtual-memory-monster.aspx

And a great artcle at codeproject: http://www.codeproject.com/Articles/32297/Visualizing-the-Windows-Mobile-Virtual-Memory-Mons

Here a screen of the app at codeproject:

Regardless of how much program memory is left, NO process will get more than the what is free in the process's 32MB slot.

It would be nice if a moderator would pin this message.

Edit: Added some articles on profiling and memory usage of CF:

Hey Josef - excellent collection of information there, especially considering that's one of the biggest headaches for new (and often not so new) mobile developers - thanks!
