So, when 1000 columns are added to the List Control using InsertColumn() function of MFC, memory usages increased by certain amount(For e.g Say by 500KB), but when we remove the added 1000 columns from the List Control using DeleteColumn() function, the memory is not freed...

With the help of Task manager.

So please suggest me some good tool which can tell me exact memory used by my application.

ITask *pITask;
  LPCWSTR lpcwszTaskName;
  lpcwszTaskName = L"Test App";
  hr = pITS->Activate(lpcwszTaskName,
                      IID_ITask,
                      (IUnknown**) &pITask);

     wprintf(L"Failed calling ITaskScheduler::Activate; error = 0x%x\n",hr);

}

I meant use Task Scheduler instead of writing a program.

class myClass
{
    private:
        static myClass* pThis;
    public:
	myClass();
//    .................
};

// static variables must be defined at file scope
myClass* myClass::pThis;

myClass::myClass()
{
    // access to the class variable can be made in any method
    pThis = this;
}
