The no of child thread depends on runtime.

CWinThread **Thread;
UINT ParentTh()

    ......
    int block;
    cnt=0;

    Thread[cnt]=(CWinThread *)malloc(sizeof(CWinThread));//gives access vilation
    .....
    while(block>0)
    {
        Thread[cnt]=AfxBeginThread(Child1...);
        cnt++;
        Thread[cnt]=AfxBeginThread(child2...);
        cnt++;

You could try something like this :) :

class CThreadPair
{
  CWinThread* m_pcThread1,
              m_pcThread2;
public:
  CThreadPair();
  ~CThreadPair();
  
  StartThreads();
  StopThreads();
}

{
  CPtrArray m_cThreadPairsArray;
  
  int iPairsCount(12);
  while (iPairsCount--) {
    CThreadPair* pcPair = new CThreadPair();
    if (pcPair) {
      pcPair->StartThreads();
      m_cThreadPairsArray.Add(pcPair);
    }
  }
  
  Sleep(20000);
  
  for (int i = 0; i < cThreadPairsArray.GetCount(); i++) {
    CThreadPair* pcPair = (CThreadPair*) cThreadPairsArray[i];
    if (pcPair) {
      pcPair->StopThreads();
      delete pcPair;
      pcPair = NULL;
    }
  }
  
  cThreadPairsArray.RemoveAll();
}
