Passing a reference of "this" ?

[jase jennings]

Hi

Is it possible to pass a reference of "this" ? I am extending the MFC CStringArray class. I need to reference the string array using the [] operator, but i cannot do this on a pointer, it needs to be on a reference to the original object. I don't have access to the actual member data (as far as i can tell from the docs)

Am i making this clear ? Here's a code snippet which will explain.

void SortStringArray (CStringArray &csa, BOOL bDescending)
{
  int iArraySize = csa.GetSize();
  if (iArraySize <= 0)
     return;

  int iCSSize = sizeof (CString*);
  void* pArrayStart = (void *)&csa[0]; // i cannot do this on a pointer, so i cannot pass a "this" pointer to this func

  if (bDescending)
     qsort (pArrayStart, iArraySize, iCSSize, CompareDescending);
  else
     qsort (pArrayStart, iArraySize, iCSSize, CompareAscending);
}

void CSortStringArray::QuickSort(bool *pbCancel /* = false */)
{
	SortStringArray(this, FALSE); // can't pass "this".  Need to pass a reference ... but how ?
}

Thanks for any suggestions.
