MFC VC ++ 2010 windows应用程序。 [英] MFC VC++ 2010 windows application.

问题描述

 我是在MFC VC ++ 2010中开发应用程序的新手。我必须开发 我项目中的一项要求。 

要求： 

我必须开发滚动条的代码。必须移动鼠标滚轮滚动。对，知道我可以通过评分来移动滚动条。但它也应该 用鼠标滚轮。

请告诉我如何实施。我也是已实施 一些代码粘贴在下面，但它不起作用。

请给我你的建议和意见。

BEGIN_MESSAGE_MAP（CMainFrame，CFrameWndEx）

        ON_WM_LBUTTONUP（）

ON_WM_MOUSEWHEEL（）

ON_WM_LBUTTONDOWN（）

END_MESSAGE_MAP（）

  void CMainFrame :: OnMouseMove（UINT nFlags，CPoint point）

{

// TODO：在此处添加您的消息处理程序代码和/或调用默认值

nFlags  = WM_MOUSEMOVE;

CFrameWndEx :: OnMouseMove（nFlags，point）;



}

void CMainFrame :: OnLButtonUp（UINT nFlags，CPoint point）

{

// TODO：在此处添加您的消息处理程序代码和/或调用默认值<
nFlags  = WM_LBUTTONUP;

CFrameWndEx :: OnMouseMove（nFlags，point）;



}

void CMainFrame :: OnLButtonDown（UINT nFlags，CPoint point）

{

// TODO：在此处添加您的消息处理程序代码和/或调用默认值<
nFlags  = WM_LBUTTONDOWN;

CFrameWndEx :: OnMouseMove（nFlags，point）;

}
