How to handle OutofMemory exceptions??

sarabjit · 01-30-2006, 08:30 PM

Hello,

I am working on a project that requires me to generate long reports that can have 150 pages or more - Each of these pages are generated as an A4 image (~3500x2480pixels), which is then inserted into an ArrayList...

The problem however is that I'm repeatedly getting OutOfMemory exceptions that I seem to be unable to get rid of despite extensively clearing all objects i'm not using (using the Image.Dispose() method for example) as well as forcing the garbage collector (GC.Collect()) every now and then...

I'm constructing each of these images in the 1bpp pixel format that would mean that each of these images would be ~1MB on average... For 200 images, this (crudely) corresponds to a 200MB ArrayList.. I agree this is a size larger than many RAMs, but shouldn't my computer be able use the pagefile (my pagefile is set to 512MB)??

Any one has any ideas on how I can get rid of, or even handle, these OutOfMemory exceptions??

Thanks,

Sarab
