Nobody is interested? Then i'll tell you how to increase GDI 32-bit heap now. 32-bit GDI heap is 2MB by default, that's pretty much; but, GDI actively utilizes this heap for storing small images and discarding DCs there. While it's not that easy to fill this heap, it is possible. With default 2MB heap worst case filling scenario would be ~200 48x48 images or ~5000 DCs (only likely if you're using leaky programs). So it's good thing to increase GDI 32-bit heap size. It would be required for heap extender to go all-out, too. Remember, this value is maximum size, not commited-at-once size. Don't ever set it smaller than 2MB. You can change this value by adding line in win.ini section [windows] (value in KB)I would think of values like: <128MB of RAM: 4096 (4MB) 128-256MB of RAM: 8192 (8MB) 256-512MB of RAM: 16384 (16MB) >512MB of RAM: 32000 (~32MB, maximum value you can set). Not likely you often run into this limit, but this knowledge is nice to recall.
