memory problem!

[jayjay60]

Hi everybody,

Perhaps a simple question but, i would like to suggest it o you:

In my application, i have an "access violation" message which appear to this following line:

*(pHistoDBNorm+ j- *(pInflex+i)- *pInflex), when i=0 and j=16, just with this indications, you will tell me to check if th e allocation is well done, but the problem is if i remove *(pInflex+i)- *pInflex (which is equal to 0), in the debug window, the following
*(pHistoDBNorm+ j) is evaluated correctly whereas
*(pHistoDBNorm+ j- *(pInflex+i)- *pInflex), always in the debug window couldn't be evaluated (instead of reading a value which would have to be the same than *(pHistoDBNorm+ j), i could read something like that:"expression couldn't be read..."

why??????

thanks in advance

It seems like pInflex is not initialized. To what value is it evaluated? Can you see *pInflex?

sorry it's right that i haven't specified that i could see *pInflex and *(pInflex+i) when the problem arrives they are equal to 15 (both because i=0)

May be you forgot parentheses:
*(pHistoDBNorm + j - (*(pInflex+i) - *pInflex))

you're right, sorry for this stupid mistake and thanks for your help
