Progress Bar Control 之 SetRange

通过两个消息设置进度条控件范围：

• PBM_SETRANGE
• PBM_SETRANGE32

本以为两个消息应该是大同小异，谁知连参数都变了，试了半天才发现：

• lResult = SendMessage(     // returns LRESULT in lResult
          (HWND) hWndControl,        // handle to destination control
          (UINT) PBM_SETRANGE,       // message ID
          (WPARAM) wParam,           // = (WPARAM) 0; not used, must be zero
          (LPARAM) lParam            // = (LPARAM) MAKELPARAM (nMinRange(默认0), nMaxRange(默认100))
          );

• lResult = SendMessage(      // returns LRESULT in lResult    
      (HWND) hWndControl,      // handle to destination control     
      (UINT) PBM_SETRANGE32,      // message ID    
      (WPARAM) wParam,      // = (WPARAM) (int) iLowLim;    
      (LPARAM) lParam      // = (LPARAM) (int) iHighLim; 
  );
