Memory Overrun! in MFC

Didn't you get the memo, Zac? Today is guess-what's-wrong-with-my-code-without-seeing-it day. ;)

there is memory overrun error & i do not know how can i solve that!
Don't overrun the end of your allocated memory. Mark

HI Mark, could you explain it further do you mean something like this int* pnSize=new int[10]; pnSize[10]=10;// which is not available delete [] pnSize;

Actually I was wrong about your code being "well done"... The original poster said "i allocate very large data". Therefore, your code sample should be: int* pnSize=new int[100]; pnSize[100]=10;// which is not available delete [] pnSize; :doh: Have a great day, Mark

excuse me for this fault, i do not know when i ignore HTML tags , the messeage is correct:confused: Netmfile.z = sizeCB * N - (sizeCB-1) * (N/2); //double *smp2; smp2 = new double [Netmfile.z]; for (i=0 ; iN/2) { for ( j=p ; j>=i+1 ; j--) pichi [ j ] = pichi [ j - 1 ] ; pichi [ i ] = N/2; pichi [ i + 1 ] = m - N/2; m=0; p++; //beacause of increase of Pitch length in each atage } i++; } return (p);

Use
delete [] Pitchinstead. Allnew[]must have a matchingdelete[].

Hi, but there is not diffrence , i think before i must use delete [] when i create two dimensional array in heap such as this: vf_Weigth = new float* [nlayer2+1]; for ( i =0 ; i< (nlayer2+1) ; i++) vf_Weigth[i] = new float[nlayer1]; delete [] vf_Weigth; // but now i find i delete in these way: for (int i = 0; i < nlayer2+1 ; i++) delete vf_Weight[i]; is that code is correct? at last i say again delete [] Pitch is not work & my code have that serios error. Best Regards. M.J.M.

You need to gain a further understanding of how
new/deleteworks, specifically with the [] notation. See: http://www.informit.com/guides/content.asp?g=cplusplus&seqNum=36&rl=1[^] http://www.cplusplus.com/doc/tutorial/dynamic.html[^] http://www.glenmccl.com/bett_003.htm[^]
