I haven´t seen documenation about it, but it always fires on my screen when my code reads/writes to a unassigned memory block. This happens very usually when working with pointers and new/delete operators. Check all the rountines using dynamic memory allocation before the point that breaks the execution of your application.

it means your process does not have access to the memory it was trying to use. like the previous poster noted, this usually means you have a bad pointer. check all your pointers - make sure they have valid values. -c

Hi all, Thanx a lot for the help. I think i try to paint u all a better pic: In my prog, I have 2 arrays. The size of the array depend on the size of my image. One array use a "new" operator to declare and the other one is using the CArray. my program uses extensive recusive function to process the image. When i try my program on a small image (eg ard 100x100 pixel) it works perfectly fine. When i try it on large images the first-chance exception occur. when the error occur, there is a lot of the recusive function being called. And the error occur at the begining of the function (no code is there). Can anyone please enlighten me what has happened and any possible solutions ?? Thanx you ! bk

Hi Probably you are trying to access memory that is read only and it might be caused by using pointers in an unproper way (maybe you haven't initialized something or you are trying to access memory that you've just released). Try to use call stack to find out where have you made that mistake. Greetings

0xC0000005 is a GPF. You read or wrote memory you didn't have access to. Usually this is a bad, uninitialized, or dangling pointer. --Mike-- Just released - RightClick-Encrypt v1.4 - Adds fast & easy file encryption to Explorer My really out-of-date homepage Sonork-100.19012 Acid_Helm
