error C2600: 'CWaitCursor::~CWaitCursor

How are you using the CWaitCursor ? Normal usage is to declare it on the stack at the beginning of a block/function and let it get destroyed automatically at the end of the block/function.

void f()
{
  CWaitCursor waitCursor;// create and display the wait cursor.

  //... do something long.

  // at the end of the function the waitCursor will be automatically destroyed and the previous cursor will be restored.

}
