比方说,我MFC新建了一个单文档应用程序,我现在想查看"文件"下拉菜单项"打开"的消息响应的源代码,,,请问我应如何操作?...........谢谢

Answer 1

Find infiles ：输入OnFileOpen，点击望远镜即可到达消息响应处。
BEGIN_MESSAGE_MAP(CMultDrawApp, CWinApp)
//{{AFX_MSG_MAP(CMultDrawApp)
ON_COMMAND(ID_APP_ABOUT, OnAppAbout)
// NOTE - the ClassWizard will add and remove mapping macros here.
// DO NOT EDIT what you see in these blocks of generated code!
//}}AFX_MSG_MAP
// Standard file based document commands
ON_COMMAND(ID_FILE_NEW, CWinApp::OnFileNew)
ON_COMMAND(ID_FILE_OPEN, CWinApp::OnFileOpen)
// Standard print setup command
ON_COMMAND(ID_FILE_PRINT_SETUP, CWinApp::OnFilePrintSetup)
END_MESSAGE_MAP()

Answer 2

ON_COMMAND(ID_FILE_OPEN, CWinApp::OnFileOpen)

楼主还是看了孙鑫老师的vc++视频在问吧。

Answer 3

在对应菜单项上选择Add Event Handler，如果已经存在就会提示你Edit

Answer 4

在视类，文档类里有重写，重写里有响应菜单的事件
