Dynamically creating an array of structures

Hi all
Win 95; VC 5.0 SP3

I am trying to create an array dynamically. this sort of works but I am
having trouble with memory leaks when destrying the array. any ideas.

CScaleThread **  ScThread;

in OnInitialUpdate()
{
....
 if (pDoc->iNumScales)
  {
  ScThread = new CScaleThread *[pDoc->iNumScales];
  }

 for (int y = 0; y < pDoc->iNumScales; y++)
  {
  ScThread[y] = 0;
  }
....
 for (int x =0; x < pDoc->iNumScales; x++)
  {
  GetDialogSize(&R);
  ScThread[x] = new CScaleThread;
  ScThread[x]->CreateThread(CREATE_SUSPENDED);
// Other stuff here
  ScThread[x]->ResumeThread();
  }
...
}

In OnDestroy()
{
 CTestscrollDoc* pDoc = GetDocument();
 if (ScThread)
  {
  for (int x =0; x < pDoc->iNumScales; x++)
   {
   if (ScThread[x])
    delete ScThread[x];
   }
  delete [] ScThread;
  }
 ScThread = 0;
}

This leaves me with a whole host of memory leaks. Why?

You did not provide the definition of a CScaleThread.  It is possible that the ctor of this object allocates but the dtor does not free.

Also make sure that your OnDestroy() is in fact being called and when (put a break point there).  If it is not being called, put the delete stuff in the the dtor of the window object or call it from some other point in the program.

Hi Dan
Thank you for your input. By commenting you "took the blinkers" off my thinking. I found that the memory leak is comming from a "tested and working" portion of the code.

Though you did not answer the question directly (because the answer lay beyound the question asked) your invaluble comment helped be find the problem. Should you want the points, please replay with an answer indicating so. If not comment as such and I can delete the question.

Many thanks
Hylton
