This is not how you use the CArray class. Use the Add method to add a new
item and allow the CArray class to handle the memory allocations and
releases. You'll find it's quite good at it and that your issues will go
away if you allow it to do what it does.

Hi,
I am using VC++ 6.0, I have an issue while deallocating the memory using
CArray removeAll. The code for the allocation is

CArray <VoxelCoord,VoxelCoord> VoxCoordArray;

myPixVoxCoordArray = new VoxCoordArray * PIXVOXCOORDARRLEN];
for(int ii = 0; ii < PIXVOXCOORDARRLEN; ii++)
             {
                       myPixVoxCoordArray[ii] = NULL;
}

                   for(int i = 0; i < PIXVOXCOORDARRLEN; i++)
                   {
                       myPixVoxCoordArray[i] = new VoxCoordArray;
                   }
               }

the code for the deallocation is
if(myPixVoxCoordArray)
{
for(int i = PIXVOXCOORDARRLEN-1; i>=0; i--)
{
if(myPixVoxCoordArray[i])
{
myPixVoxCoordArray[i]->RemoveAll(); // exception happens here
delete myPixVoxCoordArray[i]; // exception happens here
myPixVoxCoordArray[i] = NULL;
}

}
if(myPixVoxCoordArray)
{
delete [] myPixVoxCoordArray;
}
myPixVoxCoordArray = NULL;

when i try to release the memory, exception is thrown only in release mode
and the dll is build using intel compiler .Please let me know any
suitable
solution for the deallocation of memory
