Big C++ Problem

hi, i have a problem, im not gunna post the source code cause its huge :angry:anyways i am writing a 3d model editor. i have 2 versions, materials and no materials.in my no materials version i can make as many polygons as i want, on my other one i can make three and then it crashes making a material for the fourth one. i originally thought it was a memory problem and i had too much on the heap, but then again its all pointers and stuff, so i must be running out of memory some other way, even though i have 120 mb ram free!if that made sense to anyone any ideas?greatly appreciated.

I have no idea about that.But even though you've got 128MB RAM,no one program can use up all of them.It's impossible to let one program control all of the RAM, the operating system controls this.In old time,DOS mode,It's only 64KB,or even less.

are you sure you don't have any memory leaks. You must close all objects after you are done using them otherwise they stay in memory. If you don't you could choose to use virtual memory (using the HD to story temporary stuff).

thanks timstockman, i think i may have had a memory leak. i had a constructor that deleted a pointer. the problem was that the pointer didn't point to anything i had created (if that makes sense) so i fixed this and my program seemed to work fine. thanks heaps for you help everyone cheers

yeah, i actually have 256 mb of ram, just i had 128 free when i was running it. this should allow my program to have a decent chunk of memory though right?anyways i have big plans for my model editor over the next few weeks, i'll post the website when its finished. thanks for your help everyone.
